FELUCENE AND ISIDIVIT INFLUENCE ON REPRODUCTIVE FUNCTION OF SERVICING BULLS

Abstract

The studies were carried out on breeding servicing bulls of JST «RCBA «Assyl Tulik»» of Tselinograd district, Akmola region. Before the start of the studies, laboratory tests of blood, evaluation of the quality of sperm were carried out. The studied bulls were divided into 4 groups according to their reproductive abilities (high, good, low reproductive ability and unable to reproduce). Felucene in the form
of pellets 350-400 grams daily with concentrates was prescribed to the bulls of the group with good reproductive ability, and Felucene at the same dose, and a comprehensive immunosuppressive drug Isidivit, which was used intramuscularly 5 times with an interval of 3 days to 10 ml were prescribed to the groups of animals
with low reproductive capacity and incapable of reproduction. As a result of the use of the feed additive Felucene, the volume of ejaculate increased by 1.03-1.5 times in group II bulls, and by 1.03 - 1.2 times in 66.6% of group III bulls. In terms of sperm motility, group II bulls had an increase of 1.01-1.2 times, while group III bulls only
had an increase of 1.2-1.4 times in 33.3%. The concentration of sperm in the ejaculate in group II bulls increased by 1.1-1.2 times. When using a feed supplement and the introduction of a complex vitamin from group III, only 16.6% of bulls had an increase in the concentration of sperm by 1.3 times. As a result of the prescription of
Felucene to group II bulls, the glucose content increased by 3.29 times, and the calcium content increased by 1.86 times. When using Felucene and Isidivit in bulls of group III, an increase in blood glucose by 2.64 times, calcium by 1.1 times, and in animals of group IV, glucose by 2.8 times and calcium by 2 times was observed.
