Relationship of ejaculate quality and selected biochemical parameters of blood in cockerles of three laying lines
Original language description
Ejaculates and blood plasma were sampled from cocks of three laying lines:Barred Plymouth Rock (BPR),Sussex Light(SU), and Rhode Island Red(RIR).Ejaculates and blood plasma were sampled four times during the laying period of hens.The motility of spermatozoa of the cocks was 47.0%(BPR),47.7%(RIR) and 48.3%(SU),respectively. The highest volume of ejaculate was found in BPR line(0.66 cm3),the lowest one in SU line(0.46cm3,P?0.01);the highest sperm concentration was in SU line(2.46 x 106/mm3),the lowest onein RIR line(1.96x106/mm3,(P?0.01).The number of morphologically abnormal sperm cells was similar in all lines-47.0%BPR,47.7%RIR and 48.3%SU,respectively.Negative correlations were found between the level of magnesium in blood plasma and numbers of morphologically defective spermatozoa in the ejaculate,defective heads and defective connecting pieces(rp=-0.33,P?0.01;rp=-0.23,P?0.05;and rp=-0.26,P?0.05).Level of magnesium was positively correlated to sperm motility(rp=0.26,P?0.05).However,
