The influence of feeding on semen quality of livestock

The aim of this research is evaluate the quality of bull semen, that are fed different diets. Research goal of the paper: 1. Analyze and evaluate different breeding bull rations; 2. Analyze bull’s semen quality; 3. Evaluate the influence of different diets on breeding bull semen quality (semen volume, concentration, percent viable sperm, directly moving spermatozoa percent). The results of different bull’s diet show that bulls of farm B got more mineral and vitamin needed for reproductive system than bulls from farm A. The breeding bulls of farm B were given 16.4 MJ 52.35 crude protein, 20.66 g of phosphorus, 40.9 mg of copper, 859.2 mg of zinc, 28,290 IU of vitamin D and 122 700 IU of vitamin A more than bulls from farm A. This material is particularly important for the reproductive system and sperm quality. Breeding bull’s sperm quality indicators showed that the semen characteristics (volume, concentration, and right-moving sperm) were on average superior to those bulls whose diets were additionally given mineral - vitamin supplements. The semen quality of bulls is changing dependent on different bull semen volume released. It showed that increasing volume of the sperm determine decreasing in sperm concentration mln/cm3
