Fifty one dairy buffaloes in their last two months of gestation were selected at seven peri-urban commercial farms located within a radius of 70km around Peshawar. These animals were monitored from parturition until 150 days post-partum. After parturition, rectal examination of reproductive organs was carried out. Estrus detection was made through visual signs and use of intact bulls. Milk samp...

After parturition, the somatotropic axis of the dairy cow is uncoupled, partly because of reduced concentration of liver-specific GH receptor (GHR) 1A. Estradiol-17 beta(E(2)) concentrations increase at parturition and E(2) upregulates suppressors of cytokine signaling-2 (SOCS-2) mRNA expression, potentially inhibiting GH signaling. Therefore, we hypothesized that SOCS-2 mRNA is upregulated aft...

Fluctuations in Zn metabolism throughout gestation and lactation might affect Zn requirements. However, scientific data on Zn requirements for breeding sows are limited. The objective of the present study was to assess the Zn status of primiparous and multiparous sows using different Zn status biomarkers, to identify periods of critical Zn status throughout the reproductive cycle at different p...

To evaluate the effect of intrauterine cephapirin on treatment of endometritis 39 Holstein dairy cows that affected with postpartum endometritis were selected and randomly assigned to two experimental designs. In experiment 1, 6 out of 14 cows were 25 to 30 days after parturition were treated by intrauterine oxytetracycline. Another 8 cows were treated by intrauterine cephapirin (Metri-Care). I...

151 effects of the metabolic changes on, for example, fertility are not fully understood. The aim of this study was to assess the relationship between liver TAG and metabolic homeostasis. Fifteen pregnant, multiparous Holstein-Friesian cows were included in the study, which started at six weeks before the expected calving date. All animals had free access to tap water and were individually fed ...

The objectives were to determine the effect of dietary fish oil (FO) on uterine secretion of PGF2alpha, milk production, milk composition, and metabolic status during the periparturient period. Holstein cows were assigned randomly to diets containing FO (n = 13) or olive oil (OO, n = 13). Cows were fed prepartum and postpartum diets that provided approximately 200 g/d from 21 d before the expec...

A determination was made of the gestational interval over which the Subhuman Primate Pregnancy Test, a hemagglutination inhibition test for urinary chorionic gonadotropin, accurately indicated conception and the continuation of pregnancy in an orangutan (Pongo pygmaseus). The initial positive diagnostic test response occurred about 8 months before parturition and positive responses continued th...
