This Report compares the efficacies of three anthelmintics, each belonging to one of the broad spectrum groups. It also identifies the genera of resistant worms through larval culture. The study was conducted on a commercial farm where anthelmintics had been used intensively. The results show cle...
The economic and biological efficiency of cotton seed cake (CSC) and molasses urea block (MUB) supplementation to control gastrointestinal nematode parasites was examined in artificially infected Horro and Menz lambs from 3 to 12 months of age. The factorial O.xperimental design involved 2 breeds...
There is a large and diverse range of sheep and goat breeds in the world and some of these, particularly the indigenous tropical breeds, appear to have some unique genetic ability to resist or tolerate diseases. This paper reviews the information available on between-breed genetic variation for r...
Red Maasai [Masai] and Dorper sheep were evaluated for their resistance to gastrointestinal nematode parasites (predominantly Haemonchus contortus), productivity and efficiency in experiments undertaken at the Kenyan coast (humid environment) and the Kenya highlands (semiarid environment). It was...
This study is evaluating the resistance of Red Maasai sheep to endoparasite infections relative to Dorper sheep and a range of Red Maasai x Dorper crosses. The results confirm previous Reports that both Red Maasai ewes and lambs are more resistant to endoparasites (predominantly Haemonchus contor...
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...
The paper reviews the limited data available on both between-and within-breed genetic variation for resistance to helminthiasis in cattle, sheep and goats in the tropics. Topics covered include criteria of resistance, resilience or tolerance, parasite species and mode of infection, parameters to ...
