Assessment of sperm morphology in Zebu bulls, under field conditions in the tropics
(Blackwell, 2001)
Sperm morphology was studied in 302 extensively managed Zebu bulls (aged 1.5-9 years), classified as sound (n = 166) or unsound (n = 136) for breeding, under field conditions in the dry tropics of Costa Rica. Single semen ...
Comparison of the antibody response in adult cattle against different epitopes of Brucella abortus lipopolysaccharide
(Blackwell, 2001)
The comparison of serological responses in a sample of adult, vaccinated and held-infected bovines with Brucella abortus is reported. Indirect enzyme immunoassav (EIA) titration curves and Western blotting tests for ...
