Abstract [en]

Mastitis is one of the most frequent and costly diseases in the dairy industry. The sickness has been treated with antibiotics for decades, resulting in undesirable consequences for processors and consumers. Hence, it is vital to find a cheap and efficient solution for farmers to treat the cows before mastitis occurs or in early stages of the disease.

The main purpose of this study was to understand the effect of liniments on cows and find one with high efficiency to prevent mastitis. Agricam is the first company working with early detection of mastitis. Although it is known that the use of cameras serves as a useful tool for an earlier attention to the problem and potential treatment28, no studies have been done before on liniment effect with this kind of technology until now.

However, by analyzing currently existing data on a farm using Agricam liniment, it is possible to make conclusions if the liniment has had any significant effect. A normal distribution curve was performed followed by two-tailed t-test to compare the significant difference before and after treatment. The data was obtained on 100 individuals during a one-month period. Software programs Python 3.6 and Spyder 3.1.2. were used.

The results showed that the data was normally distributed for all the data that was analyzed. The t-tests showed significant effects before and after treatment with liniment A and Agricam liniment for sick and healthy cows. Similarly, the test showed a significance in non-treated cows when analyzing the temperature differences. The significance indicates an increase of temperature in healthy cows and a drop of temperature in sick cows as a long-term effect.

Same result is seen in treated cows as in non-treated cows (drop of temperature). With the current test analysis, it is concluded that there is no significant difference between non-treated, Agricam liniment treated and Liniment A treated sick cows. Same result was held for healthy cows treated with Agricam liniment and Liniment A, i.e. no significant difference.
