Abstract. An experiment was carried out for one year on six adult creole meat bucks todetermine if there were any seasonal variations in spermatogenetic activity, mating beha-viour or fertility.Every month the animals were weighed, their testicular diameters recorded, volumeand concentration of sperm of their ejaculates were measured, and sexual behaviour asses-sed. Fertility was measured in March, July and November after hand-mating.Liveweight (37.5 kg) and testicular diameter (42.9 mm) did not vary significantly withthe month but with the buck. The volume of the ejaculate (0.80 ml) did not vary with eitherthe buck or the month, and sperm concentration (3.45 x 109spz/ml) varied with the buckbut not with month.The number of matings (2.9) per behavioural test and the interval (98 s) between theonset of the test and first mating did not vary with the month or with the buck. Fertilityrate (79 %) did not vary with the season of mating.It was concluded that creole bucks are not seasonal breeders when maintained undergood management conditions. However, large variations between males would be animportant point to consider in a system where males are used intensively. |
