The effect of lasalocid on fall calving beef cows

Creator:: Hopman, Bruce T.
Abstract:: Forty-two fall-calving crossbred cows were equally allotted to six pens of seven cow-calf pairs each. Two treatments (0 and 200 mg lasalocid/head/day) with three replications were used to determine the effects of lasalocid on fall-calving beef cows. The cows were fed grass hay, haylage and pasture ad libitum. The cow-calf...

Oxytocin synthesis and release by the bovine corpus luteum

Creator:: Abdelgadir, Salaheldin Eltigani
Abstract:: Four experiments were conducted to determine oxytocin concen tration of bovine luteal tissue at different stages of the estrous cycle and to study the effects of prostaglandins F₂α (PGF₂α), E₂ (PGE₂), luteinizing hormone (LH), cycloheximide, colchicine and cytochalasin B on oxytocin synthesis and release in vitro. In experiment 1, luteal...

Gonadotropin releasing hormone-induced secretion of luteinizing hormone during the milk ejection reflex in the postpartum beef cow

Creator:: Jaeger, John Ralph
Abstract:: 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...

Gonadotropin releasing hormone-induced alteration of corpus luteum function in beef heifers

Creator:: Rodger, Lynn Dian
Abstract:: 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...
