Reproduction function and natural resistance of sire bulls when including «Seltoxorb» sorbing product in diet

Abstract

Mycotoxins have now become the main pollutants to grain and its processed products, causing significant damage to all agriculture. This paper presents the results of studies of efficiency of use of “Seltoxorb” sorbing product in the diet for sire bulls. It has been determined that developed product adsorbs aflatoxin В1 by 100%, fumonine В1 by 99, ochratoxin A by 95.4, Т-2 toxin by 86.89, DON by 69.8 and zearalenone by 60.92%. Studies have proved that “Seltoxorb” sorbent product used in the amount of 0.15% by the compound feed weight (or 6 g per animal per day) in the diet for sire bulls contributed to activation of reproductive function, which is confirmed by the increase in ejaculation volume by 5.3%, spermatozoa concentration - by 9.2%, spermatozoa count in ejaculation - by 15.2%, fertilizing ability of sperm - by 5.9 p.p., calves yield from uterus - by 6.6, daughters productivity index - by 4.0 p.p. and reduction of spermdoses rejection by 1.2 p.p. The introduction of the developed mycotoxin adsorbent into diet for sire bulls has a positive effect on body's natural resistance, which was expressed in increase in bactericidal activity of blood serum - by 11.4 p.p., lysozyme activity of blood serum - per 0.7 and phagocytic activity of neutrophils - per 5.9 p.p. The economic evaluation of the efficiency of using mycotoxin adsorbent showed that the profit from sperm sales increases by 5.2%.
