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...

using melatoninin ewes of iran black breed, this study aimed to compare the reproduction and production performances in lambing program of two and three times per years for duration of two years. a hundred ewes allocated to two parallel groups: group a (ewes in three lambing managing system using melatonin) and group b (ewes in two lambing managing system without using melatonin). to induce the...

in sheep industry, pregnancy rate after artificial insemination (ai) declines due to the complex anatomy of the cervix in ewes, such that it might prevent effective intrauterine insemination. at estrus, cervical relaxation occurs to some degree in ewes, which is regulated by the changes in the levels of reproductive hormones. this study aimed to evaluate the effects of estradiol and intravenous...

this study was carried out at sakha animal production research station, during the period from oct., 2009 to sept., 2010. forty rahmani ewes were divided into three treatment groups: the 1st, 2nd and 3rd treatment groups were intramuscularly injected (day 0) with 1 ml gnrh analogue followed by an intramuscular injection with 0.7 ml pgf2α5 (g1), 6 (g2) or 7 (g3) days later. a second dose of 1 ml...

the aim of this study was to determine the effects of ecg, pgf2α and gnrh hormone on improvement of reproduction performance of cidr synchronized zandi ewes in breeding season. 500 ewes with age of 2.5-4 years and same nutritional condition were selected for this study and received cidr for 12 days. then these ewes were assigned to five equal groups. first group received no hormone (control gro...

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...

the objectives of the present study were to investigate the prevalence of histologic thyroids lesions and the respective thyroid hormones changes of ewes in an endemic goiter region and to find out any impact of this condition on the fetal thyroid structures and serum thyroid hormones. in the present study a total number of 100 pregnant ewes and their fetuses slaughtered at slaughterhouse were ...

The present study was aimed to improve the reproductive performance of Corriedale ewes by nutritional flushing. Forty Corriedale ewes were divided into four treatment groups (TC, T1, T2 and T3) with 10 ewes in each group (n=10). At the beginning of the breeding season extra feeding (flushing regime) was started for approximately 34 days such that two estrus cycles were covered. First group i.e....
