Zaanen breed goats dairy productivity in the Krasnoyarsk SAU zoofarm conditions

The purpose of the research is to study the dairy productivity of goats of the Zaanen breed and determine the prospects for processing goat milk in the butter and cheese making industry. Research objectives: to study the milk yield for 305 days of lactation, the content of fat and protein, the amount of milk fat and protein of Zaanen goats, to recalculate the milk of the actual fat content and protein-milk content to the basic one, to determine the coefficient of the ratio between fat and protein, the yield of cheese and butter The experiment involved Zaanen goats. The system of keeping in the experiment was a stall-pasture system; in feeding the goats, rationed feeding was used, taking into account the physiological characteristics of the animals. The composition of the diet during the stall period included roughage (hay, straw), succulent (silage, root crops) and concentrated feed (compound feed). In the summer, the animals were in the pasture. Control milking of goats was carried out once a month (the amount of milk for the period of control milking was calculated with an accuracy of 0.1 kg). The selection of milk samples and research of the studied parameters were conducted by standard methods; the amount of milk fat and protein, recalculation of milk of the actual fat content and protein-milk content, the coefficient of the ratio between fat and protein, the yield of cheese and butter – by calculation methods. It was found that in Zaanen goats the milk yield for 305 days of lactation was 441 kg, the content of fat and protein was 4.5 and 3.2 %, respectively, the amount of milk fat and protein for 305 days of lactation was 19.8 and 14.1 kg, respectively. Recalculation of milk of actual fat content and protein-milk content in the base rate showed an increase in the test weight by 135 kg. The coefficient of the ratio between fat and protein in the milk of goats of the studied breed was 1.41; cheese yield – 5.4 %; oils – 11.1 %.
