A study was conducted at the Asella Station in the Arsi Region of Ethiopia to investigate the dairy performance of purebred indigenous Arsi and Friesian x Arsi crosses under different pre- and post-partum supplementary feeding regimes. Lactational performance of both genotypes was not affected by...

Milk yield, milk composition and body weight change of crossbred dairy cows (Holstein Friesian X Zebu) were studied in the urban and peri-urban dairy production systems in the Addis Ababa milk shed between December 1997 and November 1998. Ninety-seven cows, with parities above two and at the begi...

This paper presents the results of a comparative study conducted to characterize the oestrous phenonenon in Zebu and crossbred cattle and to determine oestrus detection using both androgenized cows and entire bulls. The study was conducted at ILRI Debre Zeit Research Station during the dry season...

Metabolizable energy (ME) and crude protein (CP) of the stall-fed resources met half of the requirements of crossbred cows in the Central Ethiopian highlands. The average supply of ME and CP from stall-feeding supported a milk yield of 850 kg or 55 percent of the lactation yield. The additional M...

Overall performance of smallholder crossbred dairy herds was assessed by administering semi-structured questionnaires on 20 sample herds with crossbred and indigenous cattle in Degem. Reported average lactations yields of crossbreds were at least five times greater than that for indigenous cows; ...

The effect of levels of upgrading of indigenous Ethiopian cows on the reproductive performance and herd life of crossbreds with different levels (50, 75, and 87.5%) of European inheritance were evaluated. Genetic and non genetic factors affecting herd life and reproductive performance traits such...

The effects on crossbred steer liveweight gain of alternating the same quantities of Napier grass and barley straw at five day intervals over a 40 day period was studied (Sanda et al, 1999. These animals lost significantly more weight (p<0.05) than animals on one and ten day frequencies of alter...
