Factors that influence upon the quantity of the somatic cells in cow‘s milk

Somatic cells are one of the factors which determines the quality of milk. The increased milk somatic cells affects technological properties of milk a reduction in fermentation, lactic acid and rennet operation, the milk is not thermostable. According to the somatic cell count in milk to diagnose mastitis, usually common and expensive disease of dairy cows. Genetic correlation between somatic cell count and mastitis is very high, so one feature allows you to set a different character. Financial loses due to high somatic cell count, which affects the decline in milk production and milk quality degradation is the main reason to encourage vaterinarians and breeders, monitor and analyze this indicator, as well as to invastigate and control the factors that influence somatic cell count in cows' milk. Goal of work: 1. Evaluate and analyze the factors that have an impact on the quantity of the somatic cells in cow's milk. 2. To describe the collected data by setting the diversity of breeds of cows under observance and evaluating the greatness of farm. 3. To estimate statistically and describe the impact of such factors as breed, age, season, greatness of farm, type of sample collection and the person taking it, impact on the quantity of somatic cells in the milk of the observed cows. Methods: 1. Control cow assistants involved in control of milk, take a milk sample, complete set from of documents; 2. Milk sample survey; 3. Data processing and storage. All of the factors set out the methodology that were selected for analysis, had asignificant effect in somatic cell count. Statistically, the breed and age of an animal influence upon the quatity of the somatic cells in milk. The least number of the somatic cells can be detected in the milk of the cows that are young or used to the local keeping and feeding conditions: 1. Animal species and age significantly influenced the number of somatic cells milk. The minimum number of somatic cells in the young, have adapted to the local housing conditions and feeding cow's milk varieties. 2. The greatest quality milk from the perspective of the somatic cells in aschieved in grand farms that keep over milking cows. 3. The influence of the person taking a sample on the quantity of the somatic cells in milk is confidential statisticaly. The right order of taking a sample has a crucial meaning to the further investigations on the productivity of cows
