Tegegne, AzageMukasa-Mugerwa, E.Franceschini, R.Sovani, S.[Nutritional influence on Corpora lutea function and fertility in Boran (Bos indicus) heifers bred at first oestrus or after three oestrous cycles]Nutritional influence on Corpora lutea function and fertility in Boran (Bos indicus) heifers bred at first oestrus or after three oestrous cycles

A study was carried out at the International Livestock Research Institute (ILRI) Debre Berhan Research Station in Ethiopia from 1992 to 1995 to compare the peri-parturient rise (PPR) in faecal nematode egg counts (FEC) in ewes of two indigenous sheep breeds. A total of 1439 Menz and 1347 Horro ew...


Tembely, S.Lahlou-Kassi, A.Rege, J.E.O.Mukasa-Mugerwa, E.Anindo, D.O.Sovani, S.Baker, R.L.[Breed and season effects on the peri-parturient rise in nematode egg output in indigenous ewes in a cool tropical environment]Breed and season effects on the peri-parturient rise in nematode egg output in indigenous ewes in a cool tropical environment

The effects of breed and dietary protein supplementation on the development of resistance and resilience to gastrointestinal nematode parasites (endoparasites) were examined in artificially infected Horro and Menz lambs from 4 to 12 months of age. The factorial design involved two breeds, two inf...

The effects of breed (Menz and Horro), season (wet and dry), and the breed by season interaction on production and response to naturally acquired gastro-intestinal (GI) nematode parasite infections (predominantly Longistrongylus elongata and Trichostrongylus spp. and a small proportion of Haemonc...

Although the importance of bull reproduction in enhancing genetic progress and influencing cow herd fertility has long been recognized in many parts of the world, there has been very little attention paid to bulls in Ethiopia. Proper management of young bulls aims to improve growth rate so that t...


Tegegne, AzageKassa, T.Mukasa-Mugerwa, E.[Aspects of bull reproduction with emphasis on cattle in Ethiopia. I. Sexual Development and onset of puberty]Aspects of bull reproduction with emphasis on cattle in Ethiopia. I. Sexual Development and onset of puberty

The efficiency of cattle breeding and production depends to a large extent on the reproductive performance of the herd, with the bull playing a major role. Large differences in fertilizing ability between bulls exists, and such differences are due to the characteristics of individual bulls rather...

Genetic resistance to artificially acquired gastrointestinal parasites was studied in 49 Horro and 103 Menz breeds of Ethiopia. The experimental design involved 2 breeds, 2 infection treatments (Infected vs Non infected) and 3 dietary protein treatments using 152 lambs assigned to the 12 treatmen...

Data collected on 3256 lambs born to Horro and Menz breed ewes single-sire mated to 71 rams at the International Livestock research Institute (ILRI) Debre Berhan station between September 1992 and June 1996 were analysed for rates of survival and growth from birth to weaning. A significantly lowe...

The luteolytic effect of prostaglandin F2á (PGF2á) during the confirmed luteal phase of the oestrous cycle was evaluated in ten Boran and ten Boran x Friesian cross-bred heifers. Following injection with 25mg Lutalyse, animals were bled every 6 h for 96 h and plasma progesterone (P4) determined ...
