APPLICATION OF CHELATE ADDITIVE "GIDROLAKTIV" FOR INCREASE OF REPRODUCTIVE CAPACITY OF FEMALES OF MINKS
We studied the effect of multicomponent chelate preparation GidroLaktiV on the reproductive capacity of female of pastel minks. The composition of GidroLaktiV along with chelating compounds - lactate macro-(Ca, Na, K, Mg, P) and trace elements (Co, Cu, Fe, Zn, Mn, Cr, Ni, Se) include vitamins (C, E, B <sub>1</sub>...B <sub>7</sub>, B <sub>9</sub>...B <sub>12</sub>), pro-vitamins (beta-carotene, ergosterol), oligopeptides, free amino acids, polysaccharides, various organic acids and other biologically active substances, as well as a live probiotic culture of Lactobacillus (mainly <i>Lactobacillus bulgaricus</i> and <i>Lactobacillus acidophilus</i>). The study was conducted on the base of mink farm «Pioneer» of company «Northern fur» (Leningrad region). The integrated product GidroLaktiV used in feeding females of pastel minks, since the period of mating (March), including the birth (April-May) and before separate of young minks from mothers (June). To conduct the experiment in one brigade was formed two groups of adult females of the main herd at the age of 2 to 3 years to 50 goals in each group. The ratio of age gradation in groups was similar. Mode of feeding and technology in the control and experimental groups were identical. In accordance with the scheme of the experiment the females of experimental group in addition to the diet received GidroLaktiV. The preparation is introduced into the daily feed rate of 1 g per head per day. Primary data obtained from the results of the experiment, were systematized and consolidated into a table, a statistical analysis of continuous random variables (fertility, obtained puppies on the main female and etc.) was limited to verifying the hypothesis of equality of two population averages for two samples using t-statistic of Student. The experiment results in the experimental group reported significantly (p <0.05) decrease in the proportion of stillborn pups, number of which amounted to 0.08 goals in terms of primary female that is essential to 77.78% compared with the control. In general, the use of food additive GidroLaktiV on 10.37% increase the number of obtained puppies on the main female to separate of young minks from mothers. At the same time in the group with GidroLaktiVa more than twice declined separate of young minks from birth to registration, respectively, 7.85% and 3.56% of the total number of live puppies in each group. The experiment results indicated positive effects of this preparation on the reproductive capacity of females of minks.
