Influence of nutritional value of complete feed on the chemical composition of rabbit meat

Abstract

Rabbit breeding, one of the oldest branches of animal husbandry, provides man with a wide range of agricultural products, the main one being dietary meat. Many domestic and foreign scientists pay great attention to the chemical composition of rabbit meat and the factors affecting it. It is known that the protein content in rabbit meat increases with age, but no significant difference in the protein content in rabbit meat of different breeds has been established. The article shows the dependence of the chemical composition of rabbit meat on the ratio of nutrients in the diet with a dry type of feeding. In a scientific and economic experiment on young rabbits of the Soviet chinchilla breed, the influence of the ratio of nutrients in a complete granulated feed on the chemical composition of meat at slaughter at the age of 90 days was established. It was formed on the principle of analogs of the 2nd group of young animals at the age of 45 days, 60 heads in each: group 1 - control, 2 - experiment. The rabbits were fed with full-feed granulated feed (FGF), consisting of the same plant and mineral components: barley, oats, corn, grass flour, sunflower meal, feed chalk, monocalcium phosphate, table salt. The composition of the FGF 1 of the control group contained 1% of the vitamin and mineral premix P 90-2T; the composition of the FGF of the experimental group contained no vitamin and mineral premix. The diets of the control and experimental groups differed in the ratio of protein, fat and fiber. As a result of laboratory studies by the method of full zootechnical analysis, it was found that the chemical composition of rabbit meat from the hip part does not depend on the nutritional value of the diet, and the neck part does, and the protein content is inversely related.
