A total of 35 herds of cattle from 2 inistitutional farms, and 6 privately-owned farms which were semi-intensively managed, and 17 nomadic Fulani herds were studied between January 1984 and December 1993 to evaluate the age of first calving (AFC) in the three major indigenous breeds of the Savann...

Ruminants adapt to periodic fluctuation in feed resources by accumulating fat stores during favourable periods. Thus, genetic variations, among ruminant genotypes, in the capa city to deposit fat could be exploited through breeding to improve animal productivity in traditional tropical production...

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...

Milk Production and milk constituents were studied in 95 ewes of two purebred groups, Ossimi(O) and Saidi (S), and two F1crosses with Chios(C) (CO and CS) from September 1991 to April 1993 at the Experimental Animal Farm, Faculty of Agriculture, Minia University, Egypt. Breed of ewe had an effect (p
