Twenty four male yearling Tigray Highland sheep with mean body weight (BW) of 21±2.6kg (mean±S.D.) were used to investigate the effect of different protein sources on feed intake, nutrient digestibility, BW change and carcass parameters in a study comprising of 90 days feeding trial, followed by

Goats were grazed during daytime and milked in the evening only. Kids were allowed to suck their dams during the night up to 90 days and then weaned. Milk yield and lactation length increased gradually and almost linearly by increasing level of supplementation, while fat percentage and total solids percentage declined. Differences (P < 0.05) in average daily milk yield were found between Treatments 1 and 4 for both goat breeds in both years. Milk yield was significantly higher, but fat and SNF contents were lower for Begait than for Abergelle goats. When calculated as energy corrected milk (ECM)/kg metabolic BW, no breed differences were found. There were no significant differences for calcium and phosphorus contents in milk between the breeds. It is concluded that vetch hay supplementation increased milk yield by up to 50%, but decreased percent fat and total solids in the milk of both Begait and Abergelle goats.

Kids were allowed to suck their dams freely up to 20 days of age. From day 21 after kidding, complete hand milking once a day during evenings was applied. The kids were allowed to suck for about 2 h after milking, up to day 90, when they were weaned. Vetch hay supplement at 0% BW (treatment 1), 0.5% BW (treatment 2), 1.0% BW (treatment 3) and 1.5% BW (treatment 4) was provided to both dams and kids. Body weights were recorded from birth up to maturity age (at day 270) at every 2 weeks interval.There were significant (P < 0.05) differences in birth weight of kids between the supplemented and non-supplemented group for both breeds and the tendency was consistently in favour of higher levels of supplementation. Weaning weight (at day 90) of the first experimental year was 8.0, 8.3, 9.0 and 10.4 kg for Begait and 6.0, 6.5, 6.8 and 7.2 kg for Abergelle kids and treatments 1–4, respectively. Corresponding figures for the second experimental year were 8.0, 9.2, 10.0, 10.8 and 6.3, 7.0, 8.0, 8.9 kg.Differences (P < 0.05) in weaning weight were found between treatments except in treatments 1 and 2 for both breeds. Mature weight (at day 270) of the first experimental year was 13.9, 14.5, 17.5 and 18.2 kg for Begait kids and 10.5, 13.3, 15.4 and 16.3 kg for Abergelle kids on treatments 1–4, respectively. Corresponding figures for the second experimental year were 14.7, 15.2, 16.4, 19.1 and 11.3, 13.5, 15.5, 16.4 kg. Differences (P < 0.05) in maturity weight between treatments for both Begait and Abergelle goats in both years were observed. Weight at 90 and 270 days of age increased significantly by increasing level of supplementation in both breeds and both years. Begait kids were heavier than Abergelle kids at all stages.
