Increasing resistance in infectious pathology of foxes

The aim of the study is to reveal the effect of vitamin and mineral feeding on the indicators of the content of sulfur, nitrogen and their ratio in the blood and hair in case of fox mycoses (for example, trichophytosis). 20 puppies (by the analog method) of silver-black foxes at the age of 3.5-4 months were selected. We used feeding for 2 months to healthy and sick animals against the background of control ones (5 animals in each group). Scheme of application: a week - feeding in a dose of 2.05 g per one animal, a week - rest. An important aspect of the disease under study (trichophytosis) was revealed - a violation of sulfur and nitrogen metabolism in the body of animals. Applying the developed feed for fur-bearing animals containing sulfur-containing substances, as well as essential minerals and vitamins, we helped to normalize the exchange of sulfur and nitrogen. An improvement in the general condition of animals, their activity, good digestibility of feed were noted. In healthy foxes that received additional feeding, the sulfur content by the end of the experiment increased in blood serum and hair by 32.8 and 16.2 %, respectively; in sick animals by 7.6 and 7.2 %; in comparison with the control in the experimental group in healthy animals - by 47.1 and 30.9 %, in patients - by 21.8 and 23.9 %. In healthy foxes that received additional feeding, the nitrogen content increased in blood serum and hair, respectively, by 3.6 and 4.7 %; in sick animals - by 1.8 and 3.2 %; in comparison with the control group in the experimental group of healthy foxes - by 2.1 and 4.5 %; in sick animals - by 0.17 and 0.65 %. In healthy foxes that received additional feeding, by the end of the experiment, the ratio of sulfur and nitrogen in blood serum and hair, respectively, was 1:9.54 and 1:3.81; in sick animals that received additional feeding, the ratio was 1:11.5 and 1:3.93; in the control - 1:14.7 and 1:4.83.
