In an experiment lasting from 1.5 years before, first calving until third parturition, 24 purebred indigenous Bos indicus (Boran) cows and 24 Boran crosses will; Holstein (proportionately 0.50 and 0 75 Holstein blood level) were given a diet composed of Bermuda grass hay and wheat bran (0 65: 0 3...

Presents results of a data collected over a 10-year period on 1,778 service intervals in 1,111 Arsi (Bos indicus) cows at the Ethiopian Ministry of Agriculture ranch to analyse conception rate at first service, interval between services in animals returning for insemination, the number of short c...

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.

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...

This study tested the hypothesis that purebred Boran (Bos indicus) cows and crossbreds of Boran and Holstein respond differently to long-term changes of feeding level in nutrient partitioning to milk and body fat stores. A total of 27 cows of these two genotypes were subjected either to a low or ...

This study examined the effects of lablab hay and graded levels of wheat bran supplementation on feed intake, feed degradation characteristics, apparent digestibility, milk yield and milk composition of crossbred cows fed forages from cereal crops+legume intercropping (maize/lablab (ML) stover or...
