IMPROVING REPRODUCIVE FUNCTION OF BOARS FEEDING L-KARNITIN
The paper presents the results of research on feeding biologically active additive L-Karnitin in mixed fodders to boars. The animals of control group were fed with a basic diet, boars of experiment group I - a basic ration with L-Karnitin at a dose of 150 mg/kg of mixed fodder, boars of experiment group II - 250 mg/kg and experiment group ІІІ - 350 mg/kg of mixed fodder. It was established that feeding biologically active additive L-Karnitin at a dose of 250 mg/kg of mixed fodder to boars contributed to increase of ejaculate volume by 13.28 % (P≤0.01). The highest sperm cells activity was noticed in animals of experiment group II and amounted 8.52 scores, what is by 10.08 % higher than in control group. On concentration of sperm cells boars of experiment group II surpassed analogues of control group and experiment groups I and III by 24.95 % (P≤0.05), 19.71 and 6.01 %, respectively. On sperm cell density the animals of experiment group II surpassed boars of the control group by 11.09 % (P≤0.01). It was also noticed that sperm doses quantity was higher in animals of experiment group II than in analogues of the control group by 1.38 % (P≤0.05). Doses of biologically active additive L-Karnitin 150 mg/kg and 350 mg/kg of mixed fodder influenced less on reproductive functions of boars. Thus, feeding boars with the additive L-Karnitin in compound of mixed fodder at a dose 250 mg per 1 kg of mixed fodder contributes to the increase of quantitative and qualitative characteristics of sperm.
