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...

objective: different studies have shown an association of tlr4 polymorphisms with susceptibility/resistance to malaria disease. in the current immunogenetic study, we assessed the tlr4 genotypes formed by the two common single nucleotide polymorphisms (snps) (asp299gly and thr399ile) in the co-segregate state in baluchi plasmodium falciparum infected and healthy populations from malaria hypoend...

This study included 6 groups of pregnant ewes with a change-over design. In period 1 group 1, 2 and 3 had access to the water nipples 4, 5 bowls vice versa in 2. all six both types dispensers. The ewes’ intake was significantly higher when drinking only from (3.27 ± 0.29 l/ewe day) than (2.04 0.22 (F = 78.28, P < 0.001). wastage for 36% usage negligible bowls. When offered dispensers ewes' tend...

Breeding programs for sheep in Norway are based on cooperatives of ram circles (RC). The key features of RC are selection of rams across member flocks and their rotation among RC flocks during the mating season. Genetic gains are disseminated to flocks outside RC (ORC). In both groups, natural service and AI are practiced. The objectives were to investigate 1) connectedness within and across RC...

the present study was carried out to compare different random regression models to estimate variance components of lamb&apos;s average birth weight per lambing (abwll) in mehraban sheep. the data were 5,559 abwll records of 2,244 mehraban ewes. the random regression models consisted of namely, flock-year-season of lambing as fixed effect, a fixed regression to fit average trajectory of the popu...

Baluchi sheep is the dominant fat-tail breed in Iran. We studied the microbial communities in the rumen of four Baluchi lambs fed a high concentrate conventional diet. Using DNA extracted from the rumen samples, we found the partial ribosomal rRNA of bacterial and archaeal were amplified by polymerase chain reaction (PCR). The amplicons were sequenced using 454 Titanium pyrosequencing and the d...

the aim of this study is to investigate antioxidant enzymes, oxidative stress biomarkers and the acute phase proteins levels for subclinical and clinical pregnancy toxemia and to determine the effect of early diagnosis on the success of curing. according to the results of clinical and biochemical parameters, from 39 ewes, 10 were healthy ewes (control group), 13 ewes had subclinical pregnancy t...

Granulocyte macrophage-colony stimulating factor (GM-CSF) increases ovine interferon-tau (oIFNtau) secretion by ovine conceptuses, but endometrial production of GM-CSF has not been characterized. Endometrial GM-CSF expression was evaluated in ovariectomized ewes implanted with estradiol-17beta (E(2)) and/or progesterone (P(4)) for 14 days, in day 14 cyclic and day 14 pregnant ewes. Relative lev...
