Retrospective studies were conducted in Kafta-Humera and Wukro areas of Tigray region of Ethiopia. A retrospective study was carried out on 12 herds consisting 2144 Begait cattle from pastoral and agro-pastoral areas to assess herd composition and calf-crop. To evaluate the reproductive performan...

Forty-five Bos indicus (Zebu) cows were blocked by body condition (BC) score at calving and allocated by body weight (BW) to three treatments: untreated controls (CON), and progesterone-releasing intra-vaginal device (PRID)-treated at either 45 (T45) or 60 days (T60) post partum. Cows were given ...

Slaughter data from 1547 male indigenous marketable goats (406 Afar, 389 Long eared Somali, 412 Arsi-Bale and 340 Woyto-Guji), were analyzed to compare carcass and edible-offal component yields. Dressing percentage (DP) was determined based on slaughter weight (SH). Percentage total edible offal ...

The purpose of this study was to investigate the effect of L. leucocephala supplementation on feed intake, water balance and water economy in highland sheep fed teff straw as basal diet. Sixteen young male sheep of uniform weight were assigned in a completely randomized design to the following fe...

Forage development is one of the strategies to address feed scarcity and low livestock productivity in Ethiopia. In line with government strategy, multiple actors took part in a forage development programme for six years (2004–09) in Alaba Special District, in southern Ethiopia. This paper analys...
