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...

This study examined the effect of lablab hay supplementation of crossbred cows fed forages from cereal+forage legume intercropping (maize–lablab (ML) stover or oats–vetch (OV) hay) basal diets on feed intake, apparent digestibility, milk yield and milk composition of crossbred cows. Forty eight m...

Effects of supplementation with graded levels of lablab hay on voluntary food intake, digestibility, milk yield and milk composition of crossbred cows fed maize-lablab stover or oats-vetch hay ad libitum]Integration of forage legumes with cereal crops. I. Effects of supplementation with graded levels of lablab hay on voluntary food intake, digestibility, milk yield and milk composition of crossbred cows fed maize-lablab stover or oats-vetch hay ad libitum

This study evaluated the synergism between oilseed (50:50 noug (Guizotia abyssinica) and groundnut) cake (OSC) and tanniferous feeds (pods of Acacia albida and Sesbania sesban leaves) in two experiments. S. sesban has a lower content of soluble phenolics than A. albida pods (196 vs. 270 g/kg). Di...

This study examined the interaction of high energy substrates (ES: crushed maize grain (MG) and wheat bran (WB) with forage legumes (FLs), such as Lablab purpureus hay, sun dried leaves of Sesbania sesban and tagasaste (Chamaecytisus palmensis), on ruminal microbial activity (indexed by the degra...

This study investigated the effect of feeding oats hay alone or with 250 g of dolichos lablab (Lablab purpureus, 50 percent flowering at harvest) hay, wheat middlings, leaves of sesbania (Sesbania sesban) or tagasaste (Chamaecytisus palmensis) on the growth of 66 Ethiopian Menz sheep and the nutr...

Thirty-six crossbred cows were used in a 2 X 2 factorial arrangement in a randomized block design to evaluate forages from two cropping systems (1 and 2) and feeding levels (ad libitum, (Level1)) or 80 percent of ad libitum (Level 2) on milk yield, live weight, and reproductive performance. Crops...

Thirty Ethiopian highland rams with an average body weight of 23.7 kg (S.D = 1.23) and age of 18 months and 25 East African bucks with an average body weight of 18.6 kg (S.D. = 2.06) and age of 14 months were used to study the long term effects of supplementation with the leaves of Leucaena palli...

This study (conducted in Debre Zeit, Ethiopia in 1993) examined (i) the effect of source of inoculum on in vitro dry matter (DM) digestibility (IVDMD) and gas production (GP) and (ii) the IVDMD, GP and in sacco degradability as predictors of in vivo DM digestibility (DMD( and intake. Six ruminall...

Two studies were conducted between 1991 and 1993 to assess the impact of grazing improved natural pasture at different stocking densities on animal and vegetation responses. In the first grazing season, goats of the West African Dwarf (WAD) breed were grazed at four stocking densities. Wet-season...
