Development and use of functional compound food in rabbit breeding

Complete, environmentally friendly feed with biologically active ingredients can improve the physiological condition of rabbits, increase their productivity and the quality of rabbit meat. The purpose of the work is to create and test a functional feed with prebiotic, antioxidant, immunostimulating properties and its effect on the amount of lymphoid tissue and the pH of chyme in the intestines of rabbits. For the experiment, two groups (experimental and control) of young rabbits of the Soviet chinchilla breed were formed by selecting analogue pairs of 12 heads (males) each. The duration of the experiment was 120 days. Dry feeding was used. To prepare the feed, aspen bark (Populus tremula L.), lactulose in the form of syrup, succinic acid, and lysozyme were used as natural raw materials. The main fraction includes: wheat, barley, oats, corn, dried meadow grass. The composition and technology for preparing mixed feed for rabbits “YarGAU-002-KR” with bifidogenic, antioxidant, and immunostimulating properties is proposed. The following biologically active ingredients were used: a carbohydrate complex containing the prebiotic lactulose, succinic acid, lysozyme and natural raw materials. The influence of the use of mixed feed on the number and area of lymphoid formations in the small intestine of rabbits and on the reaction of the chyme medium (pH) was studied.
