Breeding soundness of semen producing bulls, their semen quality and inter relationship of functional tests with spermatozoa motility percentage

This work was conducted to study the breeding soundness of semen producing bulls, their semen quality to functional tests and the inter relationship of these functional tests with spermatozoa motility percentage for the semen produced at National Animal Genetic Improvement Institute (NAGII). A total of 14 breeding bulls (Boran = 4, Crosses of 75% Holstein Frisian × 25% Boran = 4 and Holstein Frisian = 6) with...

Growth performance and rumen fermentation characteristics of West African Dwarf bucks fed dietary Cochlospermum planchonii rhizome

A study was conducted to investigate the optimum inclusion level of Cochlospermum planchonii in diets of West African Dwarf (WAD) goats. Twenty five (25) WAD bucks aged 6 to 8 months and assigned to five treatments (T1- T5) of five goats each were used. Goats in T1 were given normal diet and served as the control, while those in T2, T3, T4 and T5 were respectively given diets with inclusion levels of 5, 10, 20 and 40%...

Cardiopulmonary and stress responses of xylazine, acepromazine or midazolam sedated West African dwarf goats to different body positioning

West African Dwarf (WAD) goats are important source of animal protein, ubiquitous in rural Nigerian households and undergo necessary surgical procedures. Induction of general anaesthesia in goats is associated with resultant severe systemic side effects due to position-induced stress. This study investigated cardiopulmonary and stress responses of WAD goats to three sedatives in different body positioning. Six adult WAD...

Brucellosis infection dynamics in cattle and the impacts on production and reproduction in pastoral settings of Tanzania

Brucellosis is endemic in pastoral settings of Tanzania with significant socio-economic implications. However, comprehensive studies to establish its impacts had not been elucidated. A longitudinal study was conducted in order to elucidate the dynamics and its impact on production and reproduction. Initially, 464 animals were enrolled with baseline seroprevalence in each herd. Animals were bled every three months to...
