Termination of pregnancy (abortion) was successful in four of four bitches that received PGF(2)alpha (125 mug/kg bid s.c.) and in two or four bitches that received bromocryptine (62.5 mug/kg bid po) for up to 6 d beginning 43 to 45 d post ovulation. Four sham-treated controls whelped normally at ter...

Botulism was believed to be the cause of progressive symmetric myasthenia in 8 horses on a farm in North Carolina. One horse was found dead, 6 were euthanatized after becoming recumbent, and 1 affected horse recovered. Cecal and colonic contents of 2 horses were determined to contain Clostridium bot...

The objective of this study was to investigate the effects of selenium (Se) and alpha-tocopherol supplementation on uterine involution and ovarian function in dairy heifers fed a prepartum diet containing low concentrations of Se and alpha-tocopherol. Twenty-four pregnant Friesian heifers were rando...

The objectives of this experiment were to determine the effects of 0.5 mg estradiol benzoate, administered intramuscularly 24 h after removal of CIDR-B progesterone containing intravaginal devices, on the time to estrus, ovulation and peak LH concentration in dairy heifers. Ovulatory responses and p...

Elective termination of midterm pregnancy was successful in four mares using a single intra-allantoic infusion of dexamethasone solution. Duration of gestation in the experimental animals ranged from 167 to 174 days. All mares responded within 72 h, with a mean of 53.5 h from treatment to abortion. ...

The reproductive performance of cows of high and low body weight lines was evaluated in 1992-97. In the 2 lines respectively, the interval from calving to ovulation averaged 28 and 31 days (P<0.05). In cows older than 2 years, the CRs to 1st insemination were 58.8 and 70.0% respectively..

The objectives of this trial were to determine the effects of 0.5 mg estradiol benzoate administered intramuscularly 24 h after the removal of progesterone-containing intravaginal devices on the occurrence and timing of estrus, synchronized pregnancy rate and synchronized conception rate in dairy he...

The effect of supplementation with selenium and/or iodine on growth rate, mohair production and plasma concentrations of thyroid hormones in goats was studied. Male Angora goats, 3-4 months old, were treated with 0 or 1 intraruminal Se pellet, or treated intramuscularly with iodized oil at 0, 200 or...

A single preoperative dose of antibiotic proved as effective as a preoperative and 7-day postoperative course in reducing complications following rumenotomy in cattle. Exploratory rumenotomy was performed on 29 healthy Angus steers, which were allotted to the following treatment groups: (1) no antib...

The objective of this study was to examine the effect of selenium (Se) supplementation on voluntary feed intake in Se-deficient Angora goat kids and its temporal relationship to alterations in the concentrations of thyroid hormones in plasma and the activity of glutathione peroxidase in serum. Angor...

Selenium (Se) deficiency has been associated with lowered resistance to mastitis in dairy cattle. However, little published data exists on the effect of Se supplementation before calving on udder health of pastured dairy heifers. Further, the relative efficacy of injectable barium selenate and oral ...

All cows in 6 spring-calving herds were examined for pregnancy using rectal palpation, real-time ultrasonography or enzyme immunoassay of milk samples for oestrone sulfate content [date not given]. A complete set of results was obtained from 2139 cows, of which 1906 (98.1%) were pregnant and 233 (10...
