background: this study aimed to assess follicle survival after xenotransplantation of sheep ovarian tissue into male and female immunodeficient rats. we evaluated the effects of gonadotropin treatment on follicular development in the transplanted tissue. materials and methods: in this experimental study, sheep ovarian cortical strips were transplanted into the neck back muscles of 8 male and 8 ...

The adaptive nature of sociality has long been a central question in ecology and evolution. However, the relative importance of social behavior for fitness, compared to morphology and environment, remains largely unknown. We assessed the importance of sociality for fitness (lamb production and survival) in a population of mark6d bighorn sheep (Ovis canadensis) over 16 years (n = 1022 sheep-year...

The study was conducted to determine the effect of cabbage and carrot wastes supplementation on performance, blood chemistry, carcass economic evaluation sheep. Twenty four West African dwarf male sheep about 8 – 9 months old with average initial weight 9.00 ± 0.94kg were randomly allotted dietary treatments six per treatment, in a completely randomized design. received 60% guinea grass 40% con...

In the present study, real time-polymerase chain reaction was applied to analyze the expression of IGF-I and MyoG genes in Hu sheep longissimus dorsi at different growth stages and their association with meat traits. Expression of the IGF-I gene in Hu sheep differed significantly between males and females at the two day-old (0.01 < P < 0.05), one-month old (0.01 < P < 0.05), and three month-old...

Sarcocystis is one of the most prevalent parasites of domestic ruminants worldwide. This study was aimed to determine prevalence of Sarcocystis infection and molecular discrimination of Sarcocystis gigantea and Sarcocystis medusiformis infecting domestic sheep. Tissue samples from 638 sheep slaughtered at Urmia abattoir were randomly collected from February 2011 to January 2012. Genomic DNA ext...

Adonis aestivalis (summer pheasant-eye) is an annual plant with a crimson flower, distributed in southern Europe and Asia. The plant has large buttercup-like blossoms and soft, fern-like leaves. It blooms in spring and is often found as a weed in cereal fields. Like other Adonis spp., the plant produces cardiac glycosides. It is used in remedies for mild weakness of the heart, especially when a...

Haemostasis is a physiological process that prevents excessive blood loss. In laboratory, the prothrombin time (PT) and the activated partial thromboplastin time (aPTT) are used to examine clotting systems. However, the influence of sex on PT and aPTT values is unknown. The present work aimed to determine the values for PT and aPTT in adult sheep and to evaluate their dependence on the sex of t...

This study was conducted for explaining the use of combined inactivated pneumo-3 vaccine (bovine viral diarrhea, bovine herpes virus -1 and parainfleunza-3 viruses) as a diluent for sheep pox virus vaccine to be used as a vaccine for goats in one shot. 16 balady adults’ male goats were used which were seronegative against each virus used in this study. All goats were randomly divided into four ...

This paper presents (1) a brief overview of several concepts important to predator-prey behaviors of coyotes, (2) results of an enclosure study of sheep-attack, -immobilization, and -ingestion responses involving 12 male coyotes (Canis latrans) that were paired with sheep after observing various sheeppredation events by conspecifics, and (3) an analysis of sheep predation based upon operant lea...

Rice straw with abundant availability becomes very potential to be used as local sheep feed. Fermentation needs done improve the nutritional quality of rice which is quite low. The content considered in order support productivity sheep. Local one livestock commodities that provide meat. This study aimed determine digestibility dry matter and organic feed based on (oryza sativa) fermented ecoenz...
