Foliage of four multipurpose trees (Calliandra calothyrsus, Chamaecytisus palmensis, Leucaena diversifolia and Vernonia amygdalina) and a woody leguminous perennial (Lablab purpureus) were evaluated for their potential as protein supplements for sheep fed maize stover ad libitum. The chemical c...

Forty-eight heifers of two genotypes, Boran (Bos indicus) and Holstein×Boran, were allocated to three feeding levels equivalent to 1.0, 1.2 and 1.4 times calculated metabolisable energy requirements for maintenance (MEm). The experiment started at the onset of reproductive activity, when the Bora...

This study was aimed at determining the effects of feeding an energy source on nitrogen utilization by Ethiopian Menz rams. Intake, digestibility, teff straw degradation, rumen pH and ammonia-nitrogen, nitrogen balance and purine derivatives were measured in the digestibility and nylon bag studie...

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 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...

The diurnal changes in plasma concentration and urinary excretion of purine derivatives (PD) were examined in 4 steers given feed in 1 or 2 meals daily in 2, 18-day periods. In period 1, 2 steers were fed once daily (at 08.00 h) and the other 2 twice daily (at 08.00 and 16.00 h). In period 2, the...

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...

Twenty four Ethiopian highland Zebu (Bos indicus) oxen were allocated to 6 groups of 4 animals each on the basis of liveweight, age and body condition. The animals were group-fed an experimental diet consisting of 551g/kg concentrate and 449 g/kg teff straw, at the rate of 2.5 kg per 100 kg of li...
