The data on 60 Ethiopian Boran and 428 Boran‐Friesian crosses spread over 15 years (1990‐ 2004) were used to predict first lactation milk yield (FLYD) based on earlier expressed traits using multiple regression analysis and principal components analysis. In the prediction of FLYD in Ethiopian Bor...

Breed additive and non-additive effects, and genetic parameters of lactation milk yield (LYD), 305-day milk yield (305YD), lactation length (LL), milk yield per day of lactation (DM) and lifetime milk yield (LTYD) were estimated in Ethiopian Boran cattle and their crosses with Holstein in central...

Conventional productivity evaluation criteria are inadequate to evaluate subsistence livestock production, because: (1) they fail to capture non-marketable benefits of the livestock; and (2) the core concept of a single limiting input is inappropriate to subsistence production, as multiple limiti...

A comparative study on the response of four indigenous cattle breeds of Ethiopia, namely Abigar, Horro, Sheko and Gurage, to natural challenge of trypanosomosis in the Tolley–Gullele area of the Ghibe valley has been undertaken from August 2000 until August 2004. Fifty female yearlings each of Ho...

We used a partial-budget analysis to evaluate profitability of different management strategies of three genotypes of sheep in a 2 × 2 × 3 factorial experiment conducted at Debre Berhan research station in the central highlands of Ethiopia. This involved two anthelmintic-treatment levels (treated ...

Genetic diversity is the basis for present day diversified living systems and future genetic improvement needs. This diversity should be properly utilized, improved and conserved. Conservation and improvement strategies ought to be based on proper genetic characterization in association with phen...
