INFLUENCE ON THE MORPHOMETRY AND MORPHOLOGICAL RATIO OF THE HAIR OF THE THERAPEUTIC AND PROPHYLACTIC COMPLEX OF DLK IN TOXASCARIOSIS IN SILVER FOX FEMALES
The influence of a new therapeutic and prophylactic complex "DLK" (dironet, lactobifadol, keratin) on the thickness of the skin and the morphological ratio of the hair of various categories of skins of female arctic foxes of silver cellular content, during spontaneous invasion by nematodes Toxascaris leonina, was studied. The studies were carried out on females culled from the main herd (age 5-7 years) of the silver fox type Saltykovsky, bred in the conditions of LLC "Animal Breeding Farm "Vyatka" of the Kirov region. 4 (female) groups were formed, the animals of the experimental groups received additional " DLK " with the diet, with the exception of control and invasive animals. After the maturation of the winter hair cover (November), the animals were killed and the thickness of the skin and the morphological ratio of the hair of various categories were determined, the softness of the hair cover on the skins of female silver foxes was calculated. The results of the studies showed a positive effect of the complex of drugs (DLK) on the thickness of the skin, the density and morphological ratio of hair of various categories in fresh-dry raw materials. It was found that the thickness of the skin, the thickness of the hair and the ratio of the hair of the studied categories, the 1st control group, in all topographic areas of the skins did not have a significant difference in comparison with the experimental groups 3 and 4, who received therapeutic and prophylactic food with food. DLK drug. Also, according to these parameters, a significant difference was revealed between the 1st control and 2nd experimental group of silver fox females spontaneously infested with T. leonina. The difference in skin thickness in all three topographic areas was 30.6% on the side, 15.4% on the ridge, 10.8% on the rump. Difference in hair density in topographic areas: side -13.2%; ridge -13.8%; rump -11.5%, and the average value for the group was -12.8%. The difference on the skins of silver fox females in the ratio of hairs of various morphological types was: awn 31.1% (including guiding hairs) and underfur 10.9%, and the ratio of guard hair to down hair was 1: 46.4 pcs. versus 1: 34.9 pcs.
