Autor: Gebreyohannes, G. Tegegne, Azage Diedhiou, M.L. Hegde, B.P.

The study was conducted to evaluate the reproduction efficiency of zebu and crossbred cows measured by the inter-estrus and inter-service intervals using data from Bako Agricultural Research Center. The overall mean inter-estrus and inter-service intervals were 44.3 t 0.85 and 49.1 t 1.24 days, r...

Data on reproductive performance of Zebu and Friesian X Zebu crossbred cows reared under small-scale dairy farms were analysed and the effects of genotype, parity, body condition score (BCS), season, and year of calving were examined for a total of 246 calvings. Uterine involution was completed e...

Gonadal and extragonadal sperm reserves were determined in testicular and epididymal tissues obtained from 14 small highland Abyssinian Zebu (SHAZ) and from 15 Borana bulls slaughtered at the Debre Zeit abattoir. Bulls were mature and over six years of age. Body weight and scrotal circumference w...

Plasma progesterone profiles were used to monitor post-partum reproductive activity in 12 Small East African Zebu (Bos indicus) cows allocated to either supplementary or no supplementary feeding (control) with continious or restricted (twice daily) suckling regimes. Intact bulls were used for bre...

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...

The milk and meat productivity of Ethiopia's 27 million cattle is still low for the human population of 53 million, which grows at 2.9 percent yr and is expected to surpass 65 million at the end of this century. The present cattle population includes 40 percent (10.8 million) cows of breeding age...
