Small East African Zebu cows which calved during the dry season were used to determine the effects of postpartum nutritional supplementation and suckling intensity on body weight, body condition score, reproductive performance and on calf mortality and preweaning growth performance. Cows were all...

Gondal and extragonadal sperm reserves were determined in testicular and epididymal tissues obtained from ten Small East African Zebu (SEAZ), ten unimproved Borana and nine improved Boran bulls. Bulls were mature and were between 6 and 8 years of age. Body weight and scrotal circumference differe...

A total of 64 bull calves, composed of 27 Boran and 37 Boran X Friesian, were weaned at 6 months of age and divided into supplement or control groups within breed. All bulls were kept in one paddock and grazed on natural pasture. Supplement groups received 1.5 kg per head day of a diet containing...
