Aim: The aim of present study was to determine the seroprevalence of Neospora caninum infection in aborted sheep population from Hamedan province of Iran. Materials and Methods: 358 serum samples of aborted ewes were evaluated for IgG-antibodies to N. caninum using enzymelinked immunosorbent assay (ELISA). Results: 8 samples (2.2%) were found seropositive for this infection (2.05< Confidence in...

Rift Valley fever virus (RVFV) is a zoonotic bunyavirus that causes abortions in domesticated ruminants. Sheep breeds exotic to endemic areas are reportedly the most susceptible to RVFV infection. Within the scope of a risk assessment program of The Netherlands, we investigated the susceptibility of a native breed of gestating sheep to RVFV infection. Ewes were infected experimentally during th...

Insulin-like growth factors (IGF) promote follicle development, ovulation, and embryonic development affect placental fetal in many mammalian species. Therefore, this study aimed to determine the relationship between birth type, plasma concentration, mRNA expression of IGF-I Bafra ewes. A total 30 ewes, which have single (n=15) or twin gestation at least gave 2, been used as experimental animal...

OBJECTIVE The objective of this study was to investigate the effects of seasonal changes on the superovulation in Black Suffolk ewes, particularly the ovulation rate and embryo quality. DESIGN Black Suffolk ewes were superovulated either in May (n=22) or in September (n=21), 2013. After estrus synchronization with CIDR, the donor ewes were superovulated with PMSG and seven decreasing doses of...

the influence of melatonin receptor 1a gene on litter size was studied in 150 ewes from zel (n=100) and naeini (n=50) sheep breeds. two restriction fragment length polymorphism (rflp) analyses were done to determine all genotypes occurring by variations at mnli and rsai restriction sites. the m and c were the most frequent alleles in both of these breeds. the mm genotype was predominant in zel ...

This article describes the beneficial economic characteristics-productivity, exterior characteristics and growth development of offspring fleshy-woolly sheep Uzbekistan in different breeding periods. In terms wool yield, ewes outperformed native breed ewes. this case, amount at shearing is 1.26 kg (49.6%), weight after washing 0.97 (67.8%), length 2.13 cm (19.2%) higher. Lambs obtained from exp...

Iran is one of the most important mohair-producing countries in the world. Markhoz goat is the only breed producing mohair in Iran that is showing endangerment trend in its native breeding region. The aim of this study was to evaluate the genetic diversity of Markhoz goat and its color types using ISSR markers. Four primers were designed and two of them were selected based on their number of ba...
