    Determining the effects of duration and recency of exposure to environmental enrichment2016Inngår i: Applied Animal Behaviour Science, ISSN 0168-1591, E-ISSN 1872-9045, Vol. 176, s. 163-169Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Experience can help animals adapt their behaviour to fit the environment or conditions that they find themselves in. Understanding how and when experience affects behaviour is important for the animals we rear in captivity. This is particularly true when we rear animals with the intent of releasing them into the wild as part of population rehabilitation and conservation efforts. We investigated how exposure to a changing, more complex environment promotes behavioural development in juvenile trout. Four groups of fish were compared; (i) fish that were maintained without enrichment, (ii) fish that were exposed to an early period of enrichment, but were then returned to a plain environment, (iii) fish that were maintained in plain conditions, but were then exposed to enrichment towards the end of the rearing phase, (iv) a group that were kept in enriched conditions throughout the 12 week rearing period. We then assessed fish anxiety levels, their spatial learning ability, and the capacity of the fish to find their way through a barrier where different routes were presented across 4 different trials. Fish that experienced enriched conditions for the longest duration had superior spatial learning abilities, and they were better at finding the correct route to get past the barrier than fish from the remaining three treatments. Positive effects on behaviour were, however, also found in the fish that only experienced enrichment in the last part of the rearing period, compared to the control, or fish exposed to early enrichment. No effect of enrichment was found on levels of anxiety in any of the groups.

    Handling and Welfare of Bovine Livestock at Local Abattoirs in Bangladesh2014Inngår i: Journal of Applied Animal Welfare Science, ISSN 1088-8705, E-ISSN 1532-7604, Vol. 17, nr 4, s. 340-353Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The World Organization for Animal Health (OIE) allows rope casting and the tying of legs for nonhuman animals laughter without stunning. Thehandling and welfare of bovine livestock (Bosindicus and Bubalus bubalis) were studied in 8 local abattoirs in 5 districts of Bangladesh. A totalof 302 animals were evaluated. At the local abattoirs, approximately 1/3 of the cattle and water buffalo were eithere maciated orinjured/sick. The size and vigor of the animals determined the casting method. Small and weak animals were cast on concrete floors by lifting a foreleg followed by pushing, or simply by twisting the head of the animal and then binding the legs with rope. Vigorous animals such as buffalo were castusing ropes and human force. Bleeding was slow and flaying was sometimes initiated before the animals were unconscious. Pulling and tearing of the trachea and pouring of water into the exposed trache a shortly after cutting were also observed in some cases.The over all animal handling was unnecessarily rough and he OIE standards were not implemented. Animals are subjected to considerable mistreatment, and there is an urgent need for the training nde ducation of the staff in a battoirs concerning humanes laughtering practices as well as a need to build moderns laughtering plants in Bangladesh.

    Follow Up of Maternally Derived Antibodies Titer against Economically Important Viral Diseases of Chicken2018Inngår i: POULTRY SCIENCE JOURNAL, ISSN 2345-6604, Vol. 6, nr 2, s. 149-154Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The study was conducted to know the rate of maternally derived antibodies (MDAs) transfer from parents to their offspring and declining the MDAs in their chicks at 0, 7, 14, and 21 days of age against four major poultry viruses like Newcastle disease virus (NDV), Infectious bronchitis virus (IBV), Infectious bursal diseases virus (IBDV), and Avian Reo virus (ARV). The MDAs was studied on Grandparent (GP) to Parent stock (PS), and Parent stock (PS) to broiler at 30 weeks and 50 weeks of age in Cobb-500 broiler strain chicken. The MDAs was measured from serum antibody titer by indirect ELISA test. The MDAs transfer rate against NDV from GP to PS at 50 weeks of age was higher (68.82%) than at 30 weeks of age but in case of PS to broiler it was higher (66.01%) at 30 weeks of age and its persistent rate also higher (7.96%) up to 21th days of age. Against IBV, MDAs transfer rates were higher in PS to broiler than GP to PS of both ages and highest rates were revealed in PS to broiler at 30 weeks of age as 70.72%. On the other hand, among all lines MDAs transfer rates against IBDV was higher (86.94%) in GP to PS at 30 weeks of age. For ARV, the MDAs transfer rates were highest in GP to PS in both ages than PS to broiler and within GP to PS at 50 weeks of age, it was highest (94.87%) than 30 weeks of age. Accordingly, the poultry producer may help to develop an effective vaccination schedule by considering the MDAs from above experiment.

    Candidate genes underlying heritable differences in reproductive seasonality between wild and domestic rabbits2015Inngår i: Animal Genetics, ISSN 0268-9146, E-ISSN 1365-2052, Vol. 46, nr 4, s. 418-425Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Reproductive seasonality is a trait that often differs between domestic animals and their wild ancestors, with domestic animals showing prolonged or even continuous breeding seasons. However, the genetic basis underlying this trait is still poorly understood for most species, and because environmental factors and resource availability are known to play an important role in determining breeding seasons, it is also not clear in most cases to what extent this phenotypic shift is determined by the more lenient captive conditions or by genetic factors. Here, using animals resulting from an initial cross between wild and domestic rabbits followed by two consecutive backcrosses (BC1 and BC2) to wild rabbits, we evaluated the yearly distribution of births for the different generations. Similar to domestic rabbits, F1 animals could be bred all year round but BC1 and BC2 animals showed a progressive and significant reduction in the span of the breeding season, providing experimental evidence that reduced seasonal breeding in domestic rabbits has a clear genetic component and is not a simple by-product of rearing conditions. We then took advantage of a recently published genome-wide scan of selection in the domesticated lineage and searched for candidate genes potentially associated with this phenotypic shift. Candidate genes located within regions targeted by selection include well-known examples of genes controlling clock functions (CRY1 and NR3C1) and reproduction (PRLR).

    A fatal case of Listeria endocarditis in a man following his tending of goats suggests an epidemiological link which is not supported by the results1997Inngår i: Journal of Veterinary Medicine Series B-Infectious Diseases and Veterinary Public Health, ISSN 0931-1793, E-ISSN 1439-0450, Vol. B 44, nr 1-10, s. 253-256Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A man died in endocarditis due to listeriosis in the late autumn. He had been looking after two goats during the summer. Listeria monocyto?enes was isolated from a rectal swab from one of the goats. The goat faeces isolate and the human blood isolate were of identical serovar. The two isolates, however, were shown to be different by multilocus electrophoretic enzyme analysis and ribotyping, as well as by biotyping, Thus, these results do not support the hypothesis that the man was infected by the goat.

    Exposure of Farm Laborers and Dairy Cattle to Formaldehyde from Footbath Use at a Dairy Farm in New York State2014Inngår i: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 487, s. 65-71Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Formalin footbaths are commonly used in the dairy industry to prevent cattle hoof diseases. Although formalin is a well-documented disinfectant, it is also a carcinogen and irritant. The aim of this study was to estimate the exposure of farm workers and dairy cattle to formaldehyde from footbaths located in a milking facility and a heifer facility at a dairy farm in western New York, USA. The dairy farm included approximately 3900 dairy cattle including young stock; of these, 1670 cows were milked three times per day in a 60-stall carousel milking parlor, and approximately 800 heifers were located at the heifer facility where footbaths with formalin were in use. The formaldehyde concentration of the air was measured using a Formaldemeter™ htV approximately 50 cm above the 3% formalin footbaths in the milking (one footbath location) and heifer (three footbath locations) facilities on three consecutive days. The measured formaldehyde concentrations varied between 0.00 and 2.28 ppm, falling within the safety guidelines established by the Occupation Safety and Health Administration (OSHA) of the United States. Significant differences were found in the formaldehyde concentrations at the different footbath locations in the heifer facility, potentially due to the varying levels of ventilation at each location. Changes in the ambient temperature during the 3-day sampling period did not significantly affect the concentrations. We believe that the substantial ventilation at both the heifer and milking facilities ensured that the formaldehyde concentrations did not exceed OSHA guidelines, thus permitting the safe use of formalin footbaths in this farm.

    Genetic Heteroscedasticity for Domestic Animal Traits2014Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Animal traits differ not only in mean, but also in variation around the mean. For instance, one sire’s daughter group may be very homogeneous, while another sire’s daughters are much more heterogeneous in performance. The difference in residual variance can partially be explained by genetic differences. Models for such genetic heterogeneity of environmental variance include genetic effects for the mean and residual variance, and a correlation between the genetic effects for the mean and residual variance to measure how the residual variance might vary with the mean.

    The aim of this thesis was to develop a method based on double hierarchical generalized linear models for estimating genetic heteroscedasticity, and to apply it on four traits in two domestic animal species; teat count and litter size in pigs, and milk production and somatic cell count in dairy cows.

    The method developed is fast and has been implemented in software that is widely used in animal breeding, which makes it convenient to use. It is based on an approximation of double hierarchical generalized linear models by normal distributions. When having repeated observations on individuals or genetic groups, the estimates were found to be unbiased.

    For the traits studied, the estimated heritability values for the mean and the residual variance, and the genetic coefficients of variation, were found in the usual ranges reported. The genetic correlation between mean and residual variance was estimated for the pig traits only, and was found to be favorable for litter size, but unfavorable for teat count.

    Estimation of breeding values for mean and dispersion, their variance and correlation using double hierarchical generalized linear models2012Inngår i: Genetics Research, ISSN 0016-6723, Vol. 94, nr 6, s. 307-317Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The possibility of breeding for uniform individuals by selecting animals expressing a small response to environment has been studied extensively in animal breeding. Bayesian methods for fitting models with genetic components in the residual variance have been developed for this purpose, but have limitations due to the computational demands. We use the hierarchical (h)-likelihood from the theory of double hierarchical generalized linear models (DHGLM) to derive an estimation algorithm that is computationally feasible for large datasets. Random effects for both the mean and residual variance parts of the model are estimated together with their variance/covariance components. An important feature of the algorithm is that it can fit a correlation between the random effects for mean and variance. An h-likelihood estimator is implemented in the R software and an iterative reweighted least square (IRWLS) approximation of the h-likelihood is implemented using ASReml. The difference in variance component estimates between the two implementations is investigated, as well as the potential bias of the methods, using simulations. IRWLS gives the same results as h-likelihood in simple cases with no severe indication of bias. For more complex cases, only IRWLS could be used, and bias did appear. The IRWLS is applied on the pig litter size data previously analysed by Sorensen & Waagepetersen (2003) using Bayesian methodology. The estimates we obtained by using IRWLS are similar to theirs, with the estimated correlation between the random genetic effects being −0·52 for IRWLS and −0·62 in Sorensen & Waagepetersen (2003).

    Genetic Control of Residual Variance for Teat Number in Pigs2013Inngår i: Proc. Assoc. Advmt. Anim. Breed. Genet., AAABG , 2013, s. 538-541Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The genetic improvement in litter size in pigs has been substantial during the last 10-15 years. The number of teats on the sow must increase as well to meet the needs of the piglets, because each piglet needs access to its own teat. We applied a genetic heterogeneity model on teat numberin sows, and estimated medium-high heritability for teat number (0.5), but low heritability for residual variance (0.05), indicating that selection for reduced variance might have very limited effect. A numerically positive correlation (0.8) between additive genetic breeding values for mean and for variance was found, but because of the low heritability for residual variance, the variance will increase very slowly with the mean.

    Early experiences modulate stress coping in a population of German shepherd dogs2013Inngår i: Applied Animal Behaviour Science, ISSN 0168-1591, E-ISSN 1872-9045, Vol. 146, nr 1-4, s. 79-87Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Early experiences may alter later behavioural expressions in animals and these differences can be consistent through adulthood. In dogs, this may have a profound impact on welfare and working ability and, it is therefore interesting to evaluate how experiences during the first weeks of life contribute to shaping the long-term behaviour. We analysed data from 503 dogs from 105 litters, bred at the Swedish Armed Forces Dog Kennel. For each dog, the data comprised information on dam and sire, sex, litter size, sex ratio of litter, date of birth, and weight at birth, and at 10 days of age. Between the ages of 377 and 593 days, the dogs were tested in a temperament test, assessing their suitability as working dogs. The behaviour test comprised 12 different sub-tests, and was scored on a behavioural rating scale. A principal component analysis showed that the test performance could largely be attributed to four principal components (explaining 55.7% of variation), labelled Confidence, Physical Engagement, Social Engagement and Aggression. We analysed the effects of the different early life variables and sex on the principal component scores (PC scores) using linear modelling. PC scores on Confidence were affected by parity, sex and litter size, and Physical Engagement was affected by parity, growth rate, litter size and season of birth. Social Engagement was affected by growth rate and sex, and Aggression was affected by sex. Some of these effects disappeared when they were combined into a single linear model, but most of them remained significant also when controlling for collinearity. The results suggest that the early environment of dogs have long-lasting effects on their behaviour and coping styles in a stressful test situation and this knowledge can be used in the work with breeding of future military or police working dogs.

    Analyses of pig genomes provide insight into porcine demography and evolution2012Inngår i: Nature, ISSN 0028-0836, E-ISSN 1476-4687, Vol. 491, nr 7424, s. 393-398Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    For 10,000 years pigs and humans have shared a close and complex relationship. From domestication to modern breeding practices, humans have shaped the genomes of domestic pigs. Here we present the assembly and analysis of the genome sequence of a female domestic Duroc pig (Sus scrofa) and a comparison with the genomes of wild and domestic pigs from Europe and Asia. Wild pigs emerged in South East Asia and subsequently spread across Eurasia. Our results reveal a deep phylogenetic split between European and Asian wild boars approximately 1 million years ago, and a selective sweep analysis indicates selection on genes involved in RNA processing and regulation. Genes associated with immune response and olfaction exhibit fast evolution. Pigs have the largest repertoire of functional olfactory receptor genes, reflecting the importance of smell in this scavenging animal. The pig genome sequence provides an important resource for further improvements of this important livestock species, and our identification of many putative disease-causing variants extends the potential of the pig as a biomedical model.

    Purebred Dogs and Canine Wellbeing2013Inngår i: Journal of Agricultural and Environmental Ethics, ISSN 1187-7863, E-ISSN 1573-322X, Vol. 27, nr 3, s. 417-430Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Breeders of purebred dogs usually have several goals they want to accomplish, of which canine wellbeing is one. The purpose of this article is to investigate what we ought to do given this goal. Breeders typically think that they fulfil their wellbeing-related duties by doing the best they can within their breed of choice. However, it is true of most breeders that they could produce physically and mentally healthier dogs if they switched to a healthier breed. There are a few breeds that are healthier than other breeds as well as mutts; we could maximize wellbeing for the next generations by focusing all our breeding resources on those. However, in the long run such a strategy would severely deplete the canine gene pool. If we are to breed for wellbeing in the long run, we must thus weigh the benefits of selection against physical and mental problems against the benefits of genetic diversity. The optimal breeding strategy for canine wellbeing is to preserve many breeds, though not all of them. Furthermore, we ought to combine strict health programs with looser barriers between breeds. Such a policy conflicts with the goal of breed preservation, at least if we think of breeds as populations registered within kennel clubs rather than types of dogs, but not with the goal of producing good working dogs capable of performing various tasks.

    The importance of the DMRT3 'Gait keeper' mutation on riding traits and gaits in Standardbred and Icelandic horses2015Inngår i: Livestock Science, ISSN 1871-1413, E-ISSN 1878-0490, Vol. 176, s. 33-39Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Previous studies have shown that a single base-pair mutation, a change from cytosine (C) to adenine (A), in the DMRT3 gene affects both the ability to show ambling and lateral gaits in a wide range of horse breeds, as well as racing performance and trotting technique in Standardbred and Nordic trotters. The variant allele is present in gaited breeds but is absent, or found at a very low frequency, in breeds used for Western-European style riding and flat racing, like the Swedish Warmblood and Thoroughbreds as well as in draught horses. This indicates that the variant allele might have a negative effect on certain riding performance traits in horses. Therefore, one aim of this study was to investigate whether the DMRT3 variant affects canter in Standardbred trotters, and to test if heterozygous horses (CA) were better suited for Western-European style riding than homozygous horses (M). Riding traits were studied in 115 Standardbred horses, and a similar study was also performed with data from 55 Nordic trotters. The results showed that CA Standardbreds had significantly better balance in canter, both collected and extended canter, than M horses. The CA horses also got significantly higher scores for transitions in collected canter. For the rhythm we found no significant differences between the genotypes. In the Nordic trotters we were unable to establish any significant difference for canter ability. Another aim of this study was to investigate the effect of the variant allele on riding abilities and gaits in the Icelandic horse (n=446). Practically all horse breeds considered to be three-gaited have a CC genotype, in contrast Icelandic CC horses can show tolt We therefore tested whether the variant influenced how difficult it was to initiate tolt training for these horses. It was also investigated whether the variant affects which gaits Icelandic horses choose, both at liberty and during initial training. Icelandic CC horses were significantly more difficult to train to tolt compared to CA and AA horses. The M Icelandic horses showed the lateral gaits tolt and pace significantly more frequent, both at liberty and during initial training, than CA or CC horses. The majority of the Icelandic CC and CA horses chose trot at liberty and during initial training.

    Rennomadismens dilemma: det rennomadiska samhällets förändring i Tuorpon och Sirkas 1760-18601989Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The areas of study for this dissertation are the Turopon and Sirkas lappbyar (communities) in the parish of Jokkmokk during the period 1760—1860. The starting point for discussion is a decrease in population through migration to Norway, from 667 inhabitants in 1781, to 353 in 1868. The primary cause was the ecological instability of reindeer herding with recurring crises caused by poor grazing, adverse snow conditions, epizootics, and predators. The stability in reindeer herding is finally determined by the numbers of grazing animals and the carrying capacities of the pastures. A disturbance in the balance between people and animals could occur if competition from the settlers limited available pastures, or the government through taxes appropriated so much of the surplus that the subsistence level was markedly increased. A closer examination reveals, however, that no outside influences can be indicated as being responsible for the population decline.

    Attention must thus be directed toward the inner social processes of this pastoralist society. While the reindeer herding population diminished, the total number of reindeer remained on a relatively constant level. The resulting process of accumulation consolidated the reindeer into the hands of fewer owners. While these conclusions indicate an economically differentiated society, the marriage pattern shows that the social distance between the economic groupings was very small.

    By promoting economic differentiation, trade had an important potential as agent of social stratification. This potential was, however, not fully realized. The equalizing factors were stronger than the differentiating forces.

    Moocall – en sensor med koll på kalvningar2018Rapport (Annet vitenskapelig)
    Abstract [en]

    It may be a challenge for beef and dairy farmers to predict when a cow is close to calving, to move her to a calving pen in time and to properly monitor and assist the calving. The objective was to evaluate how a calving alert system, attached to the tail, affects the cow. The system monitors the tail’s movements, and the farmer is notified via a text message approximately one hour before calving. 

    A case-control and an interview study with farmers were carried out. In the case-control study, cow behaviour was observed during and after the procedure attaching the calving alert system on the tail. Controls were equally prepared, but the sensor was first attached and immediately removed again. The ethogram protocol contained for example back arching, tail lifting, fidgeting and kicking. 

    The case-control study had to be discontinued due to sensors causing damage on the tail. Results from the interview study shows that 80% of the interviewed farmers stated that the cows behaviour reaction was negative when the sensor was attached to the tail and that it lasted up to one hour. Almost all farmers had observed damages on the tails after using the sensor and 20% had observed such severe damage that amputation was necessary. 

    The studied sensor functioned well technically according to the interviews, but the observed tail damage indicates that the cows experienced discomfort by the sensor and that using the sensor is associated with welfare problems for the cows.

    Abstract [en]

    Biosecurity is important for a healthy livestock production; it may be defined as the prevention of disease causing agents entering or leaving any place where livestock including poultry are present. A number of biosecurity measures are available to minimize the risk of introducing and of spreading diseases of which some are zoonotic; i.e. diseases transmissible between animals and humans.

    This report provides information on biosecurity measures safeguarding animal health and animal welfare and it highlights topics such as barriers and motivation to  biosecurity, training and education, value of partnership and economy.

    Broadly speaking biosecurity describes the process and objective of managing biological risks associated with food and feed production in agriculture and fisheries.

    Den lyckliga pensionathunden: Tillståndspliktiga hundpensionat och hunddagis i Skåne2015Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Länsstyrelsen i Skåne ville ha bättre översikt och skapa sig en bättre uppfattning om hur många hundpensionat och hunddagis som finns i länet idag. För att uppnå detta ville man genomföra en undersökning av hur det ser ut i dagsläget. Därför valde vi att göra en inventering av samtliga verksamheter inom området.

     

    För att djurskyddet ska hålla samma kvalitet över hela landet och för att inspektionen ska hålla en jämnare standard gick ansvaret för djurskydd över från att vara kommunernas ansvar till att bli länsstyrelsens den 1 januari 2009. Länsstyrelsen är idag den enhet som ansvarar för att tilldela tillstånd att bedriva verksamheter som till exempel hunddagis och hundpensionat och även se till att dessa verksamheter uppfyller kraven som ställs i Djurskyddslagen (1988:534) samt föreskriften Statens jordbruksverks föreskrifter och allmänna råd om hållande av hund och katt (SJVFS 2008:5). Om länsstyrelsen ska klara detta behövs en god kännedom om de verksamheter som finns och hur det bedriver sin verksamhet.

     

    För att inventera hunddagis och hundpensionat började vi med att ringa till Skånes 33 kommuner för att begära ut de tillstånd de hade utfärdat och godkänt innan ansvaret gick över till länsstyrelsen. Vi jämförde länsstyrelsens register med kommunernas och sorterade ut de verksamheter som inte länsstyrelsen fått in i sina diariesystem från kommunerna. Slutligen gjorde vi en genomsökning på sociala medier för att få fram de verksamhetsutövare som annonserade om sina tjänster på internet.    

     

    De hunddagis och hundpensionat som vi befarade bedrev sin verksamhet olagligt åkte vi, tillsammans med länsstyrelsen, ut och gjorde en inspektion på. I resultatet kan vi visa att det finns verksamheter som inte har tillstånd idag av olika anledningar och vi kan presentera alla verksamheter som bedrivs i Skåne idag samt kortfattat beskriva de verksamheter vi gjort en kontroll på. Utförliga beskrivningar av verksamheterna bifogas som kontrollrapporter. För att belysa varför det är viktigt med en god tillsyn av dessa verksamheter har vi också genomfört en litteraturstudie av hur hundar påverkas av att vistas på hundpensionat eller hunddagis. Litteraturgenomgången visar att hundar kan bli stressade i hundpensionatmiljö och hur man med enkla medel kan förhindra att stressnivån blir så pass hög att den påverkar hundens välmående.

    Effects of an odor or taste stimulus applied to an artificial teat on the suckling behavior of newborn dairy calves2018Inngår i: Journal of Animal Science and Technology, E-ISSN 2055-0391, Vol. 60, artikkel-id 16Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: In their first days of life, dairy calves in artificial rearing systems often have difficulty using an artificial teat for feeding. Methods: We examined the age at which calves are able to stand up voluntarily and suckle as well as their suckling behavior when presented with a plain dry teat versus a dry teat modified with a presumably attractive odor or taste substance. Single-housed newborn dairy calves (n = 51) were presented for ten consecutive days with a two-minute two-choice test, in which suckling time was recorded for 1) a plain (control) teat versus a glucose-coated teat (taste test) and 2) a plain teat versus a teat with a "Freshly Cut Grass" odor (odor test). Results: On average, the calves were able to stand up voluntarily and suckle from the second or third day of age on. The "Freshly Cut Grass" odor had no significant effect on their suckling behavior. In contrast, the calves showed a significant preference for suckling the glucose-coated teat and displayed a significantly longer total suckling time in the taste test compared to the odor test. There were no significant differences between sexes regarding suckling behavior. Conclusion: The results of the present study show that glucose had a significant effect on the calves’ teat preference and significantly increased total suckling time with a dry artificial teat. As such, glucose may increase suckling motivation in non-efficient drinkers or ill calves with low motivation to suckle
