A study was conducted to determine the effect of the milk ejection reflex on exogenous gonadotropin releasing hormone (GnRH)- induced release of luteinizing hormone (LH) after short term calf removal. Twenty-four postpartum multiparous beef cows were assigned 3 randomly to groups arranged in a 2[superscript 3] factorial design to be...
The littoral zones of seven reservoirs in the southern Willamette Valley of Oregon were sampled with a boat electroshocker during the summer months of 1995 and 1996. Shoreline substrates were inventoried before sampling sites were randomly selected. Sampling sites consisted of 9 of 12 possible habitat types including four substrate...
Nursery plants are often harvested, stored, and shipped bare-root for easier and more economical handling. Some species of woody and herbaceous perennials are less tolerant of postharvest handling than others. Desiccation stress during the handling of bare-root plants has been identified as a major problem contributing to poor survival and...
Clostridium perfringens is a spore-forming pathogenic bacterium that causes a variety of diseases in human and animals. C. perfringens type A isolates produce enterotoxin (CPE) causing food poisoning (FP) and non-food-borne (NFB) gastrointestinal (GI) diseases including antibiotic-associated diarrhea and sporadic diarrhea. C. perfringens type A food poisoning currently ranks as...
Two experiments were conducted to evaluate the effects of
gonadotropin releasing hormone (GnRH) on the function of the bovine
corpus luteum during the estrous cycle. In Experiment 1, 10 heifers
were assigned randomly into two groups with each heifer serving as
her own control. Heifers in Group I (n=5) were...
