Both epidermal growth factor (EGF) and transforming growth factor (TGF) play an important physiological role in the processes of proliferation and differentiation of several different cell types. However, the expression profiles of these factors in domestic bitches endometrium are still poorly recognized. The aim of the present study was to identify and analyze the differential expression of th...

Managerial and economic efficiencies of cattle reproduction systems that are seasonal in nature are most likely to benefit from having a compact calving season. Effective replacement heifer development is a critical segment of the integrated management program in an efficient beef cow production system. The replacement heifer represents the future profitability and genetic improvement of the co...

Reproductive organ development, plasma sex steroid concentrations and fur growth patterns were determined for pubescent and adult mink of both sexes, at 1tc~ 8-week intervals, between July and the following June. Plasma estradiol concentrations and weights (mg/kg) of ovaries, oviducts and uteri decreased slightly in both pubescent and adult females during the first half of anestrus (July to Oct...

Background: The hair goat of Anatolia is a breed that has adapted to rugged and mountainous areas known be very resistant diseases. As the world faces problem climate change, we believe knowing hematological characteristics goats will provide great benefits for breeding. Objectives: This study was performed determine possible differences in blood parameters adult (male female) during out breedi...

Anestrus is essential to an unsuccessful pregnancy in dairy cows. One of the many factors that influences anestrus inactive ovary. To characterize detail plasma metabolic pro- file, cows suffering from ovaries were compared with those natural estrus. The Holstein 60 90 day postpartum intensive farm assigned into groups (IO, n=20) and estrus group (CON, n=22) according signs rectal palpation ova...

AIM This study was conducted to determine the incidence of major reproductive problems of dairy cattle reared under a semi-intensive system by small and marginal farmers in Meghalaya province of North-Eastern India. MATERIALS AND METHODS In a 3 years study, a total of 576 crossbred dairy cattle (212 Holstein Friesian cross and 364 Jersey cross) from all districts (n=11) of Meghalaya were asse...

The extracellular matrix of the cervix that comprises collagen, elastin, proteoglycans and glycosaminoglycans (GAGs) is thought to have an essential role in cervical relaxation. This study investigated the proportion of collagen and smooth muscle as well as the GAGs in cervices obtained from healthy bitches at different stages of the estrous cycle and bitches with open- and closed-cervix pyomet...

Objective: To describe the seasonal variations throughout year (day length), as one of main environmental cues used by ewes to determine most favorable time for breeding. Design/methodology/approach: A description factors affecting ewe reproduction (photoperiod, suckling, postpartum period, nutrition, sociosexual effects) was assessed a review documentary information. Results: The inhibition re...

The effect of treatment for anestrus in buffaloes with a PGF2α or GnRH injection and vitamin-mineral (Vit-M) supplementation for 1 to 2 months and some factors influencing the treatment effect were studied. In anestrus buffaloes with CL, an injection of PGF2α tended to show higher estrus detection and pregnancy rates within 17 days after treatment than Vit-M supplementation (P<0.10). In those w...
