Effects of four different basal diets on the carcass composition of finishing Borana bulls

Twenty four Borana bulls (average weight 218 ± 6.3 kg) were randomly assigned to 4 finishing diets to study the effects of basal diets on carcass composition. Diets were: R1 (teff straw 30%, local hay 10%, haricot bean straw 10%, molasses 20%, corn grain 20% and haricot bean grain 10%), R2 (teff straw 10%, haricot bean straw 20%, maize stover 10%, molasses 15%, corn grain 25%, noug cake 10% and linseed cake 10%),...

Anopheles species abundances, composition and vectoral competence in six areas of Lagos: Nigeria

Malaria is a problem in Nigeria and the risk exists throughout the country. Anopheles mosquitoes have been incriminated as the major malaria vectors. Vectors competence, however, differs from one species to another and from place to place. The present study reports the species abundance, composition and vectoral competence of Anopheles species in six areas of Lagos in Nigeria. The human blood index (HBI) and...

Isolation and cloning of IGF-1R gene in bovine

Gene cloning, or molecular cloning, has several different meanings to a molecular biologist. A clone is an exact copy, or replica, of something. Molecular biologists exploit the replicative ability of cultured cells to clone genes. Recent advances in the Restriction enzymes technologies have opened up new opportunities in biotechnology and facilitate the way to isolate any gene from any source of cells. Many...

Effects of season on the quality and in vitro maturation rate of Egyptian buffalo (Bubalus bubalis) oocytes

Recent advances in in vitro maturation, fertilization and culture technology allowed progress in an increasing the number of off springs produced from genetically superior females but this progress still has important factors affect the yielding and quality of the oocytes. It was referred that, there is a distinct similarity in season profile between an in vitro and in vivo reproductive traits. The influence of season...
