Embryonic mortality in pubertal gilts

Creator:: Archibong, Anthony Effanga
Abstract:: An experiment was conducted to compare the reproductive performance and serum concentrations of progesterone and estrogen of mated first (n=18) and third (n=18) estrous gilts slaughtered in equal numbers on days 3, 15 and 30 postmating. Fertilization rate did not differ between mated first and third estrous gilts. Embryonic survival...

Influence of protein supplementation frequency on cows consuming low-quality forage : performance, grazing behavior, and variation in supplement intake

Creator:: Schauer, Christopher Scott
Abstract:: Our objective was to determine the influence of CP supplementation frequency (SF) on cow performance, grazing time, distance traveled, maximum distance from water, cow distribution, DMI, DM digestibility, harvest efficiency (HE), percentage of supplementation events frequented, and CV for supplement intake for cows grazing low-quality forage. One hundred-twenty pregnant (approx....

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...

Some effects of estradiol on ovine luteal function

Creator:: Akbar, Abulfatah Maqsood, 1938-
Abstract:: Some effects of 171β-estradiol on ovine luteal function were studied in five experiments. Estradiol injected into ewes on days 11 and 12 of the estrous cycle caused luteal regression in both intact and unilaterally hysterectomized ewes indicating that the presence of one uterine horn permits estradiol to cause luteolysis comparable...

Glutathione peroxidase and selenium distribution in semen and reproductive tissues of farm animals

Creator:: Alabi, Nathaniel Sigismund
Abstract:: This study was conducted to investigate the distribution of glutathione peroxidase (GSH-Px) and selenium in semen of the boar, bull, ram and stallion, and in the reproductive tissues of the boar, bull and ram. The effect of repeated noncryoprotective freeze-thawing on GSH-Px activity was also studied. Both hydrogen peroxide (H₂0₂)...

Supplementation with lasalocid three times weekly to stocker cattle on pasture

Creator:: DelCurto, Timothy
Abstract:: Two experiments were conducted to study the efficacy of feeding lasalocid to cattle on pasture on a three times weekly basis. In experiment 1, 72 crossbred yearling steers were stratified across a randomized block design of 12 pens including three replications of four treatments. Treatments consisted of: (1) .45 kg...

Studies on luteinizing hormone and gonadal steroids in male and female llamas (Lama glama)

Creator:: Reed, Pamela J.
Abstract:: A series of studies was performed to more clearly evaluate gonadal function in llamas. Luteinizing hormone (LH) and progesterone (P₄) concentrations were compared following natural or hormone-induced ovulation. Luteal regression was evaluated following administration of the prostaglandin F₂α analog cloprostenol. The interaction of age, season and castration on testosterone (T)...
