Forty-five Bos indicus (Zebu) cows were blocked by body condition (BC) score at calving and allocated by body weight (BW) to three treatments: untreated controls (CON), and progesterone-releasing intra-vaginal device (PRID)-treated at either 45 (T45) or 60 days (T60) post partum. Cows were given ...

Assesses the effect of cow-calf association and continuous suckling on the resumption of oestral activity; and monitors the temporal patterns of plasma progesterone during the post-partum period in grazing Ethiopian Small East African Zebu cows under uncontrolled mating.

Hybridization between wild and domestic bovine species occurs worldwide either spontaneously or by organized crossing. We have analysed hybridization of banteng (Bos javanicus) and zebu (Bos indicus) in south-east Asian cattle using mitochondrial DNA (PCR-RFLP and sequencing), AFLP, satellite fr...

Approximately 390 East African Zebu calves from birth to 3 years of age and their dams were monitored monthly from 1986 to 1992 in nine village herds in an area of high trypanosomiasis risk in southwest Ethiopia where there was resistance to all available trypanocidal drugs. Cattle were individua...

An experiment was carried out to evaluate dairy performance and rumen fermentation from a forage-based diet supplemented with Leucaena leucocephala (leucaena) and maize bran. Bos indicus (Ayrshire/Brown Swiss) X Bos taurus (Sahiwal) cattle were offered Pennisetum purpureum (napier grass) ad libit...

The paper evaluates the effects of forage type and level of concentrate supplementation on forage intake, diet apparent digestibility, purine excretion and milk production. Twelve crossbred cows (Bos taurus X Bos indicus), in early lactation were allocated to the following six dietary treatments:...

Analyses reproductive data on 4123 inseminations from 2332 breeding records of 1237 Arsi (Bos indicus) cows, collected between 1982 and early 1989 from the Gobe ranch of the Ethiopian Ministry of Agriculture where cows were kept under similar management; and concludes that long post partum anoest...
