Changes in milk productivity and quality of goat milk when including cake and probiotic in the diet

Relevance . One of the solutions to reduce food waste is to try to get the most out of food waste and byproducts. The experiment assessed the milk productivity and milk quality of lactating Nigerian goat goats when using hemp cake on the background of a probiotic substance. Methodology . The research was carried out in 2 stages: in the 1st experiment, the effect on the digestibility of nutritional components of feed was studied as a result of the inclusion of waste from the fat and oil industry in the diet of goats in the amount of 5% hemp (QL) cake, in the 2nd experiment, the enzymatic probiotic drug “Cellobacterin+” (“Biotrof” LLC) was additionally included in the experimental group at a dosage of 10 g/goal /day. Results . According to the research results, it was found that the inclusion of hemp cake in the diet of lactating goat goats did not have a negative effect on milk yield and milk quality, and contributed to a reduction in the cost of its production. The additional introduction of the probiotic drug “Cellobacterin+” into the diet contributed to an increase in milk yield in goats, in the conditions of the Southern Urals, and improved the chemical composition of milk, in particular, increased fat and protein content.
