Les donnees recueillies en 1990 et 1991 sur 200 petits elevages de chevres suivis dans le cadre du Projet caprin de Ngozi ont mis en evidence un pic de mortalite entre mars et juillet chez des chevreaux ages de moins de 6 mois. Afin de simuler la survie de cohortes de chevreaux independamment des...
A study was conducted at the Asella Station in the Arsi Region of Ethiopia to investigate the dairy performance of indigenous purebred Arsi and Friesian X Arsi crosses under different pre-partum and post-partum supplementary feeding regimes. A total of 343 first-lactation animals were involved in...

Weight of lambs weaned (at 150 days) per ewe per year (Index D, per kg liveweight of ewe per year (Index II), per kg metabolic body weight (W0.73) of ewe per year (Index III), and per lifetime of ewe regardless of ewe weight (Index IV), were computed for 3022 ewes at Malya and West Kilimanjaro re...
Twenty-five year (1965-89) data on the Blended goats from Malya Research Centre totalling 4799 records were analysed for live weights and growth traits from birth to 72 weeks of age. The Blended goat developed in Malya, Tanzania, is a stabilised three-way cross of the Kamorai (55%), Boer (30%) an...
