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...

Twenty-four multiparous Zebu × Friesian crossbred cows, were fed maize-lablab stover as basal diet and allocated to four graded levels of lablab hay (0%, 0.4%, 0.8% and 1.2% BW) treatments in a study to investigate effects of levels of lablab supplementation on body weight changes and reproductiv...

The study investigated the effect of work on the postpartum estrous cycle length and ovarian activity of crossbred dairy cows used for draught. Sixteen dairy cows were assigned to two dietary feeding regimes (i.e. diet 1=9 MJ ME/kg DM; diet 2=10 MJ/kg DM). The cows in both diets started to work a...

Livestock are central to the livelihoods of livestock-dependent systems in Africa, particularly pastoralists and agro-pastoralists. Over the years, however, climatic extremes in this sub-region have impacted the agricultural production systems including livestock - dependent systems and hence th...

This study was carried out to assess feed resources and nutritional management of dairy cows in market oriented urban and peri-urban dairy production systems in and around Addis Ababa between September-November, 1998. Three sub dairy production systems, i.e. intra-urban, large peri urban and urba...

Genetic resistance to artificially acquired gastrointestinal parasites was studied in 49 Horro and 103 Menz breeds of Ethiopia. The experimental design involved 2 breeds, 2 infection treatments (Infected vs Non infected) and 3 dietary protein treatments using 152 lambs assigned to the 12 treatmen...

African animal trypanosomosis constrains agricultural production in areas of Africa that hold the continent's greatest potential for expanded agricultural production. Previous studies indicate that the incidence of trypanosomosis: (i) reduces calving rates by 1-12 percent in tolerant breeds and b...
