The effect of caffeine administration to diluted semen on the progeny in rabbit.

Abstract:

The effect of two caffeine preparations was studied on lhe reproductiva parameters (conception rale, litler size and weighl, sex ratio of the offspring) in rabbits. In the experiment, Al was carried out on 78 lactating females (divided into 3 groups). Group A was inseminated with diluted semen containing 1 mg Coffeinum Natrium Benzoicum per millilitre, group B was inseminaled wilh diluted semen containing 1 mg Coffeinum Natrium Sallcylicum per millílitre, group C was inseminated with caffeine free diluted semen. The caffeine salicylate improved the conception rate (73.08, 100, 71.88 %) (P<0.01). There was no effect of caffeine on the litter size and weight. In the treated groups the rate of new-bom male rabbits increased significantly (65.97 and 63.06 vs. 49.26 %) (P<0.01).
