Two groups of 24 Hampshire and 26 Suffolk purebred ewes each were used to study effects of cohabitation with cyclic white-faced (WF) ewes on estrous activity in June. Ewes lambed in January, February and March and had been isolated from mature rams since the previous fall breeding. From June 1 to July 2, treated (T) ewes were exposed to vasectomized rams and to 65 WF ewes; control (C) ewes were...

In late pregnancy, energy deficits in ewes can induce a metabolic imbalance, which often results in pregnancy toxaemia. This metabolic disorder is characterised by hypoglycaemia, hyperketonaemia, an increase in plasma concentrations of free fatty acids and by fatty infiltration in the liver. The purpose of the present study was to identify alterations in lipid and triglyceride-rich lipoprotein ...

The objective of this study was to compare weight and quality of fleeces of different F1 ewe types produced from breeds with a broad range of fleece types. Weights of 629 fleeces produced during 1988 through 1991 from F1 ewes that were daughters of Suffolk and Targhee dams and Finnsheep, Combo-6, Booroola Merino, St. Croix, and Barbados sires were recorded. Staple length was measured on the mid...

St. Croix White hair sheep ewes lambing in July (n = 20) or November (n = 26) were used to evaluate the effect of ram exposure on uterine involution and postpartum luteal function. Ewes were exposed to an epididymectomized ram (EXPOSED) beginning on d 7 after lambing (d 0) or kept isolated from rams (CONTROL) through d 63. The width of each uterine horn was measured using transrectal ultrasonog...

Studies were conducted to evaluate uterine motility and fertility of ova in ewes either given or not given supplemental selenium/vitamin E (SSE or NSE, respectively). The ewes were maintained on either an adequate plane of nutrition (APN) or an inadequate plane of nutrition (IPN). In a fertility study, 60 ewes were allotted to four treatment groups, (15 ewes per group): SSE-APN, NSE-APN, SSE-IP...

________________________________________________________________________________ Abstract This study was conducted to evaluate the effect of breed types and lactation status on reproductive performance of hormonally-treated Awassi ewes. A total of 282 ewes were treated with intravaginal progestagen sponges and equine chorionic gonadotropin. Ewes were mated with fertile rams following sponge rem...
