The study was conducted to determine the influence of season on ejaculate characteristics and semen quality of artificial insemination bulls at NAPRI i.e bulls made up of charolis, Bunaji, Sokoto Gudali, Friesian and FRx Bunaji bulls, over a 2 year period. Semen was collected twice weekly and eva...

The live weight of Matabele does kept in seven communally grazed flocks in southern Zimbabwe were established by survey over a two-year period. The does showed a cyclical change in weight around the breeding cycle, the mean live weight at mating, immediately after kidding and 60 days after kiddin...
