A static model for predicting either the growth rates or digestible organic matter (DOMI) required to meet predetermined levels of growth is developed. Parameters in the model were derived using data collected in ILRI-DZ laboratory from 6 growth studies (involving a total of 242 Ethiopian Menz sh...
Sixteen rumen fistulated Ethiopian Menz type sheep were used in a completely randomized block design in experiment 1. Unchopped teff straw was fed alone or supplemented with either 100, 150 or 200 g/d of sun-dried vernonia leaves. The chemical composition of fresh, boiled, water-soaked and sun-dr...
Twenty five rumen fistulated Ethiopian Menz sheep were used in a completely randomized block design to determine roughage utilization when different types of supplements (sesbania, leucaena, cotton seed cake (CSC) and forms (fresh or dry leucaena) were fed. The chemical composition, intake, diges...
The effect of Acacia angustissima on rumen fermentation was evaluated. Acacia angustissima was fed to two groups of cannulated Ethiopian highland sheeOne group (three animals) was directly supplemented with 300 g per head day-1 of sun-dried A. angustissima. These animals died after 9 and 21 days ...
In vitro gas production, dry matter and nitrogen degradabilities of fresh and sun-dried foliages of four fodde trees (FTs) (Sesbania sesban, Leucaena leucocephala, Chamaecytisus palmensis (tagasaste), Vernonia amygdalina) and of teff straw were estimated. In Experiment 1, feed samples were incuba...
A series of trials were conducted to study the effect of either nitrogen source or supply pattern on the growth, rumen fermentation pattern and utilisation of straw by Ethiopian Menz sheeAll experimental sheep were given teff straw basal diet (CON). Irrespective of the trial, treatment sheep were...
The effect of five multipurpose trees (MPTs), Acacia angustissima, Acacia saligna, Chamae-cytisus palmensis, Leucaena pallida and Sesbania sesban on ciliate protozoa was investigated in rumen cannulated Ethiopian sheeBoth entodiniomorphs and holotrichs were counted. The protozoa counts from S. se...
Nine different accessions of Sesbania sesban were examined for their toxicity to ciliate protozoa from sheep receiving a mixed grass hay-barley/fishmeal concentrate in Aberdeen, Scotland. Several accessions were much more toxic than those (ILRI 10865, ILRI 15036) identified and tested in a previo...
Thirty-six male Ethiopian Menz sheep, given maize stover supplemented with either cottonseed cake, noug cake or sunflower cake with or without maize grain, were used in an 88-day study comprising growth and balance trials. There was no significant interactions. Sheep consumed significantly more s...
