Variations in semen characteristics rams of Ouled Djellal breed have received an important dietary supplement after regular and intensive collection

Abstract

Abstract Objective To evaluate the effect of an important dietary supplement on sperm quantity and quality breeding rams of artificial insemination center Belhandjir in region of Naama in Algeria. Methods Ten breeding rams of the white arab breed, called Ouled Djellal are divided into two groups CR and SR, and subjected to two different diets, the first group CR followed a regime R based of barley and fodder and the second SR group to follow a regime R + a vitamin and mineral dietary supplement for a 15 weeks of regular collections followed by 12 weeks of intensive collections. Analysis of sperm quality and quantity were performed to normal and intensive collection. Results The quantitative effect is more significant in rams supplemented SR, volume and concentration were higher in rams SR (respectively+40% and ±, therefore the doses produced differ significantly compared to the group of control rams CR (+70%). Results of qualitative parameters were more mixed, motility showed a significant difference in rams supplemented with against the rate of dead semen and the rate of anomalies did not show significant differences in sperm. Conclusion Supplementation could significantly improve the quantitative semen characteristics in rams breeding Ouled Djellal. Collections of semen on the rams may be daily without sperm quantity is affected.
