چکیده (انگلیسی):

Objective: To evaluate the effect of an important dietary supplement on sperm quantity
and quality breeding rams of the three main breeds of sheep at the artificial insemination
center, called Belhandjir, in the region of Naama in Algeria.
Methods: Twenty-four breeding rams of the three major breeds in Algeria, namely
Ouled Djellal, Hamra and Rumbi breeds are divided into two groups CR and SR, and
subjected to two different diets. The first group CR followed a regime R based on barley
and fodder and the second SR group to follow a regime R + a vitamin and mineral dietary
supplement for 15 weeks of collection. Analysis of sperm quality (motility) and quantity
(volume, concentration and doses produced) were followed after collection.
Results: The quantitative effect was more significant in supplemented rams SR, volume
and concentration were higher in rams SR. Therefore, the doses produced differ significantly
compared to the group of control rams CR. Results of motility were more mixed,
motility showed a significant difference in rams supplemented of Ouled Djellal breed
only; however, the other two breeds Hamra and Rumbi, showed no significant
differences.
Conclusions: Supplementation could significantly improve the characteristics of quantitative
sperm in the breeding rams of the three main Algerian sheep breeds. Motility, only
qualitative parameter studied, was not significantly improved.
