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

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.
