Monitoring of fatty farming corives of extreme dairy pores of Ukraine

Aim. The “breed” was used as one of the genetic factors and as a result the genetic and mathematical analysis of fat content on cow’s milk and the output of milk fat depending on the origin mainly in Kharkiv region have been carried out. Methods. Studies were performed on materials pedigree registered in Kharkiv region agribusinesses and farms in Institute of Animal research, NAAN of Ukraine, on the cows of Ukrainian red and pockmarked and black and pockmarked breed. Results. The highest fatty dairy products are distinguished by animals of the Ukrainian red- and pockmarked milk breed (3.9 %), while the cows of Ukrainian black- and pockmarked milk are lower (3.81 %). As for the milk fat, there is a reverse trend, the cows of Ukrainian black- and pockmarked milk breed have a higher yield of milk fat in milk (167.4 kg) than cows of Ukrainian red -and- pockmarked milk (161.6 kg). Conclusions. The fat content in the milk of Ukrainian red -and- pockmarked currant dairy breeds is 3.9 %, while the cows of Ukrainian black- and pockmarked milk breed 3.81 %. The yield of milk fat from cows of the Ukrainian black- and pockmarked milk was 167.4 kg, while in cows of Ukrainian red- and pockmarked breed 161.6 kg. The "breed" factor has a significant (P > 0.999). Keywords: вlack- and pockmarked, red- and pockmarked, breed, factors, milk.
