Method of live animal express assessment of sheep fur raw materials based on bioelectric potential of biologically active centers

Sheep breeding has historically been the leading branch of agricultural production in Russia, characterized by low cost and high environmental safety of the products. Based on the results of the established correlations, one can judge the functional state of the whole organism of animals and their individual systems. It was found that the level of bioelectric potential of superficially localized biologically active centers (LBPSLBAC) of rams and indicators of fur coat productivity are interrelated. LBPSLBAC was measured in rams according to the indicated methods. After measurements of LBPSLBAC, the rams were killed, the sheepskin was removed. The animals of the control group, which were characterized by a low LBPSLBAC, had a lower weight of raw sheepskin and, accordingly, its area, in comparison with similar indicators of rams of the experimental group, respectively, by 3.7 kg and 5.42 dm2, with statistically significant differences. It was found that the animals of the control group, which had a lower UBPSLBAC by 4.20 mkA as compared to the animals of the experimental group, which had a skin thickness indicator lower by 0.01 mm, with unsubstantiated differences. In the rams of the experimental group, the density of fur tended to increase by 1.3 thousand per 1 cm2, higher than in the control. From the obtained data, it can be observed that the length of the awn - by 0.8 cm, the length of the under hair - by 1.2 cm and the height of the coat - by 0.6 cm in the rams of the experimental group were higher than in the control group.
