Presents results of a study undertaken to investigate the relationship of Packed Cell Volume (PCV) and Eggs Per Gram (EPG) to performance, and to estimate the repeatibility of the two measurements in a monthly parasite monitoring scheme. Includes data on body score, live weight of milk teeth male...
A selection programme (PNSO) was set up in 1983 in Cote d'Ivoire to increase growth and liveweight of the indigenous Djallonke sheep, using open nucleus breeding system. Selection was based on male individual weight at 80, 180 and 365 days of age. 10,417 records on 80 day weights (WT80) of lambs ...
The Menz and Horro highland sheep breeds are being evaluated at the ILCA Debre Birhan research station in Ethiopia for between-and within-breed genetic variation for resistance to internal parasites. The experimental design involves mating, for each breed, 150 ewes with 10 rams to lamb at the beg...
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...
Research in Kenya has confirmed that Red Maasai sheep are more resistant to gastrointestinal parasites than Dorper sheep and has shown that Small East African goats are more resistant than Galla goats. There is no difference in resistance between the Menz and Horro sheep breeds in Ethiopia. Herit...
Africa is well endowed with a diversity of breeds and strains of livestock, which have proved remarkably suited to survive and produce under prevailing environmental rigours. Over 90 percent of the ruminant population in Africa is indigenous, although the numbers of distinct breeds of cattle, she...
Investigates environmental sources of variation influencing growth traits of the Dorper and Dorper X Red Maasai sheep with special reference to the relative performance of various geneotypes. Lamb traits studied were weights from birth to yearling and absolute growth rates between adjacent stages...
Ensuring that locally adopted breeds are a functional part of production systems is the most national and sustainable way to conserve animal genetic resources. This can only be possible if sustainable breeding strategies for such animals are developed which take into account their economically im...
