Hypo and hyper thermic stress effects on Moringa extract extender from male tukeys administered Moringa leaves and seeds extracts.

Résumé

The thermic effects on semen samples of male turkeys administered Moringa leaves and seeds extracts were examined after being diluted with Moringa extract as an extender at different levels (0%, 50% and 100%). A total of 36 male local turkeys were used for the experiment. The male turkeys were administered aqueous extract from Moringa olerifera seeds and leaves. The turkeys were assigned into four treatment groups consisting of T1 (0% extract), T2 (100%seed extract) T3 (50%seed and 50%leaf extract) and T4 (100% leaf extract). The treatments was replicated three times. Each treatment had nine turkeys with three turkeys per replicate. Semen collection was done using locally fabricated tools. The collected semen were subjected to thermal stress at 370C (hypo) and 460C (hyper) for a period of 90minutes. Progressive motility was evaluated very 30minutes with an aliquot of each treatment sample under a warm microscope. The semen was combined with the extender at the rate of 1:5 (semen: extender). The result showed that there were no significant (p > 0.05) on the extenders as well as the temperature variation effect from the water bath. However there were significant difference (P<0.05) on sub group effect of on hyper thermic conditions, which is an indication that the administered extract had a significant positive effect on the motility rate of sperm cells of local turkeys in the hyper thermic (460C) condition. The leaves extracts alone (T4) were significantly highest, while the seeds extracts (T2) was better than the combination effect (T3) when
compared with the control (T1). Therefore since there were no significant difference among the extenders (B, C) and the control (A). It then becomes imperative to conclude that; to reduce cost and use locally available materials, using Moringa leaves and seeds extracts will go a long way to boost local turkey production by an average Nigerian farmers at the rate of 50% Moringa extract to real extender at 460C.
