The effect of genotype (50%, 75% and 87.50, levels of milk (2 and 3 1/day) and types of housing (Barn and Hutch) on growth and survival were examined using thirty four crossbred calves Boran x Freisian (Bos Taurus x Bos indicus). Calves had access to a complete diet supplement (180 g/kg CP and 10...

Based on the promising results obtained from on-station, the cow traction study was further taken to on-farm for verification under the Ethiopian smallholder farmers management conditions. The study was undertaken in Holetta area between 1992 and 1996 by involving 14 farmers. Mean dairy milk yiel...

This study examined estrus response, estrus response interval and pregnancy rate of Bos indicus and B. indicus x B. taurus crossbred cows and heifers after oestrus synchronization. A total of 101 non-pregnant and cycling animals, composed of 63 Boran (46 heifers and 17 cows) and 38 Boran-Simmenta...

Evaluates the growth performance of calves born to Boran cows and weaned at either six or eight months. Early weaned calves were further divided to either receive supplementary feed until eight months of age or serve as controls. There was no significant differences between Boran and crossbred ca...

Persistency of lactation in indigenous and crossbred cows was studied using milk data collected at Bako Agricultural Research Centre. Persistency was measured using three methods vis a vis as the ratios of milk yield during the second (P2:1) and third (P3:1) 100 days of lactation to milk yield du...
