Slaughter data from 304 Menz and 153 Horro ram lambs were analyzed to determine between breed differences in yields of carcass and edible non-carcass components. Average age at slaughter was 515 days. Total edible non-carcass component yield (ENCC) was obtained as the sum of weights of blood, lun...

Associations among chemical properties, in vitro digestibility and ruminal degradability characteristics of herbaceous legumes, browse species and oilseed cakes were studied using correlation analysis based on a total of 50 feedstuff samples. Chemical properties were poorly related to in vitro or...

The effect of subclinical artificial nematode parasite infection on dry matter intake (DMI), apparent digestibility (AD), efficiency of feed utilisation (EFU), plasma protein (PPC) and albumin concentrations (AC) was examined in lambs of the Horro and Menz breeds. The factorial experimental desi...

Milk yield, milk composition and body weight change of crossbred dairy cows (Holstein Friesian X Zebu) were studied in the urban and peri-urban dairy production systems in the Addis Ababa milk shed between December 1997 and November 1998. Ninety-seven cows, with parities above two and at the begi...

In Ethiopia, the agricultural sector is a cornerstone of the economic and social life. The sector employs 80-85 per cent of the population and contributes 40 per cent to total GDP. Smallholder farmers dominate the agricultural sector. The highlands hold about 95 per cent of the cropped area and s...

A study was carried out to investigate the reproductive management and reproductive performance of dairy herds in the intensively managed urban and peri-urban dairy production systems of the Addis Ababa milk shed between September 1997 and January 1998. Fifteen dairy farms from intra-urban, 20 ...

An on-farm monitoring study was carried out in the urban and peri-urban dairy production systems in the Addis Ababa milk shed to assess variations in on farm nutrient intake of dairy cows (Holstein Friesian X Zebu) and feed balance. Ninety seven cows, with parities above two and at the beginning ...

The effect of dietary protein supplementation on the resistance of lambs to endoparasites was examined in Horro and Menz lambs artificially infected with Haemonchus contortus. The experimental design involved 2 breeds, 2 infection treatments (infected Vs non-infected) and 3 nutrition treatments. ...
