Ruminants adapt to periodic fluctuation in feed resources by accumulating fat stores during favourable periods. Thus, genetic variations, among ruminant genotypes, in the capa city to deposit fat could be exploited through breeding to improve animal productivity in traditional tropical production...

The effects of breed and dietary protein supplementation on the development of resistance and resilience to gastrointestinal nematode parasites (endoparasites) were examined in artificially infected Horro and Menz lambs from 4 to 12 months of age. The factorial design involved two breeds, two inf...

Effect of supplementation with non-conventional agro-industrial by-products on rumen fermentation pattern and microbial nitrogen supply was studied in sheep fed grass hay for 9 days. Diets consisted of hay alone (control); hay supplemented with tela atella (traditional brewery residue); katikala ...

Data from 454 Menz and Horro male sheep at Debre Berhan Research Station, Ethiopia, were evaluated for slaughter characteristics. Rams were born from October 1992 to July 1996 and reared together from birth to slaughter at about 17 months of age. Pre-slaughter live weight (PSW) was about 25 kg, w...

This study characterized the degradability of cowpea (Vigna unguiculata) and Dolichos lablab (Lablab purpureus) hays (trial 1) and the effect of these legumes on rumen ammonia concentration (RAC), particulate passage rate (K1) and intake (trial 2) and the degradability of teff (Eragrostis tef) st...

Urban and peri-urban dairy production systems are among the many forms of dairy production systems in the tropics and sub-tropics. The systems involve the production, processing and marketing of milk and milk products that are channelled to consumers in urban centres (Rey et al., 1993; Staal and ...

Postpartum ovarian activity was investigated in dairy cows in urban/peri urban dairy production systems in and around Addis Ababa using milk progesterone profiles. Nineteen crossbred (Friesian x Zebu) dairy cows which calved between March and June 1998 were used for the study. Milk samples were c...
