Potential Mechanisms and Challenges to Regulate Fertility in Dairy Cows
نویسندگان
چکیده
In ruminants, regression of the CL is due to a positive feedback loop between endometrial prostaglandin (PG) F2α (PGF2α) and luteal oxytocin secretion (Flint et al. 1992). The common factor associated with luteolysis in cattle and sheep appears to be an increase in endometrial sensitivity to oxytocin due to presence of oxytocin receptor (OTR) that may lead to initiation of luteolysis (McCracken et al., 1999).

Animal Factors Condition Milk Performance and Quality of Grazing Dairy Cows
The base of this review is to consider the relevant role that animal factors (potential milk yield, body weight, body condition score, state of lactation, parity and fertility) play on milk performance (considering the energy balance and the rumen function across the full lactation curve of animals) and milk quality (milk protein content, milk fat content, milk lactose content, vitamins, minera...

The daily challenge of getting cows pregnant is nothing new to any dairy producer. What is new is the variety of approaches that researchers are taking to understand the mechanisms underlying this problem and propose effective solutions to it. Our applied reproductive research program is focused on controlling ovarian physiology to optimize fertility of lactating dairy cows. Our goal is to deve...

Objective: Ceftiofur, a third-generation cephalosporin, is used as a usual antimicrobial drug in veterinary medicine. Positive efficiency of ceftiofur for treatment of retained fetal membrane (RFM) and acute puerperal metritis has been previously reported. Thus, this study was conducted to evaluate the efficiency of ceftiofur hydrochloride (CH) in prevention of uterine postpart...

The objective of this study was to determine the effects of two different time of GnRH injection after artificial insemination (A.I) (d 6 and d 12) on reproductive performances of Holstein cows during the warm season. Cows randomly assigned to treatments 1) No GnRH injection (control, n = 300),2) GnRH injection at day 6 after A.I (G6, n=300) and 3) GnRH injection at day 12 after A.I (G12, n=30...
