Causes for pre-implantation embryo loss, which can be as high as 50% or more of fertilized embryos, are multifactorial and largely undescribed. Studies in cattle using mastitis as a model indicate that one cause of early embryonic loss is infectious

Problem Infertility can accompany mastitis in cattle. Involvement of tumor necrosis factor-alpha (TNF-alpha) in this phenomenon is suggested by observations that circulating concentrations of TNF-alpha are elevated after intramammary infection or inf

During summer, 34 cows received daily injections of placebo or 25 mg of bST and were placed in a thermoregulated or a heat stress environment. Heat stress increased rectal temperatures, respiration rates, and plasma cortisol concentrations and decrea

Increases in SCC are an expression of inflammation events in the udder. Inflammation events are sporadic, of variable amplitude and duration, and can be analyzed by computer programs designed to evaluate pulses of hormone secretion. Baseline values f

Objectives were to determine 1) in vitro effects of bST on function of polymorphonuclear leukocytes and lymphocytes and 2) in vivo effects of bST on leukocyte function of heifers fed to maintain medium or high growth rates. When administered in vitro

PROBLEM Mastitis and immunization against constituents of organisms causing mastitis can reduce fertility of cattle and sheep, respectively. For the current experiments, it was hypothesized that these effects are mediated via actions of lipopolysacch

Function of polymorphonuclear leukocytes (PMNL) and proliferation of lymphocytes after stimulation with mitogens were evaluated in vitro at incubation temperatures of 38.5 and 42 C, and after in vivo heat stress of lactating Holstein cows. Cytochrome
