This experiment was one part of a larger study investigating problems of aggression towards females by male broiler breeder fowl. To investigate causal mechanisms, we were interested in determining (1) if feed-restriction during rearing affects behaviour towards females at sexual maturity and (2) if aggressiveness towards females is correlated with general levels of aggressiveness. We compared ...

Severe myocardial necrosis was produced in virgin Sprague-Dawley rats without preexisting arteriosclerosis and in breeder Sprague-Dawley rats with various degrees of arteriosclerosis by giving two subcutaneous injections of isoproterenol; the virgin rats received 50 mg/100 g and the breeder rats 25 mg/100 g body weight. Breeder rats withstood the stress and shock of myocardial necrosis with few...

Scientific Solutions designed and fabricated a 14.5 GHz charge-breeder ECR source for the Texas A&M University Cyclotron facility. This charge-breeder source was designed as a charge-breeder from the start rather than as a conversion of an existing ECR system. In addition, the overall system was designed to be modular so that various components can be easily substituted to facilitate technology...

This study aims to determine the character and phylogenetics of β-lactamase Temoneira (blaTEM) gene in Escherichia coli isolated from reproductive tract Bali cattle with repeat breeder cases. was conducted June 2021 that used 16 female cases take their fluid using a plastic sheet gun. Isolation coli, Eosin Methylene Blue Agar identified by biochemical tests. Antibiotic susceptibility test on E....
