Abstract:

The purpose of the research was to study the feasibility of using by-products of the industrial processing of fruits for the production of full-feed mixed fodders with the possibility of using these mixed feeds as the only feed in the diets of herbivorous fur animals (nutria, brown muskrat, steppe marmot). Studies of chemical composition and nutrition have shown that non-traditional ingredients can be included in the composition of feed. At their expense, you can save up to 30% of leguminous feed, 9% – cake, 1% – meat and bone meal. This allowed us to reduce the cost of the studied batches of feed by 18–21%. Experiments have shown the effectiveness of using such feed in the diets of herbivorous fur-bearing animals. The inclusion of compound feed in the diet allowed to increase the number of commercial offspring per female muskrat by 0.8 heads, compared to the control group. The safety of young animals until the moment of depositing puppies from their mothers was approximately equal in both groups. Young muskrats of the experimental groups had 5.5–6.8% higher values of average daily increments, compared to control analogues. A similar pattern is established in male nutria. Marmots of the experimental group from the very beginning of the experiment were outnumbered by control animals. In July, these differences reached statistically significant values: 4,085 ± 71 g vs. 3,736 ± 73 g (p < 0.01). Thus, the marmots of the experimental group recovered faster after winter hibernation.
