Genotypic reaction of foxes (vulpes vulpes l.) on the inclusion in the diet of succinic acid

The genotypic reaction of foxes (Vulpes vulpes L.) of two genotypes: silvery-black (bb) and red (AABB) to inclusion of succinic acid in the diet was investigated. The drug was added to the feed of young animals starting with the deposition from mothers at the age of two months (beginning of July) and ending with the slaughter of animals at the age of seven months (end of November) to obtain skins. Succinic acid was included in the diet at the rate of 5 mg per kg of live weight for 10 days at the beginning of each month from July to November (5 months, 50 injections of drug). Quality indicators of the skin were determined in accordance with GOST 2790-88. Succinic acid has had a significant impact on the size of the skins: zero size was 12.5% of the foxes silver-black genotype, a 3.35% of red foxes were the size 00, to 6.65% - size of 0, indicating a significant influence of succinic acid on the consolidation of red foxes. The number of defect-free skins silver black genotype was 75% compared to 70% of the red foxes, which indicates the improvement of the quality of the fur of silver foxes. Objective evaluation of the influence of succinic acid on the overall distribution of skins in size groups and defects allows to make a test on the quality: foxes silver-black genotype in the control group received 102,58% vs 103,60% of individuals in the experimental group, respectively, on the genotype of the red foxes the drug also had a positive impact - of 105.25% vs 106,30%, respectively. Thus, foxes of different genotypes react differently to the inclusion of succinic acid in the diet. Silvery-black fox reacts to the introduction of the drug mainly by accelerating the formation of the skin and its derivatives, red fox - increasing live weight.
