Understanding Puberty and Postpartum Anestrus
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...
متن کاملPhysiological mechanisms controlling anestrus and infertility in postpartum beef cattle.
Postpartum infertility is caused by four factors: general infertility, lack of uterine involution, short estrous cycles and anestrus. The general infertility component is common to any estrous cycle and reduces potential fertility by 20 to 30%. Incomplete uterine involution prevents fertilization during the first 20 d after calving but is not related to anestrus. Short estrous cycles prevent fe...
متن کاملIncidence of postpartum anestrus among buffaloes in and around Jabalpur
Aim: Postpartum anestrus is one of the major problems in buffalo reproduction; the knowledge of its incidence may be helpful to adopt preventive and therapeutic measures for improvement of reproductive efficiency and thus production of the dairy animals. Materials and Methods: To investigate the incidence of postpartum anestrus, a total 6105 Murrah and upgraded Murrah buffaloes were surveyed in...
متن کاملUnderstanding Postpartum Anestrus and Puberty in the Beef Female
Management of the beef female for reproductive success, both before and after puberty, plays a major role in determining the efficiency of any beef production system. Two of the most critical physiological periods associated with female reproduction are the prepubertal and postpartum periods. Therefore, a general understanding of the processes that underlie developmental changes in the heifer d...
متن کاملComparison of pharmacokinetics and pathology for low-dose tacrolimus once-daily and twice-daily in living kidney transplantation: prospective trial in once-daily versus twice-daily tacrolimus.
BACKGROUND A prolonged-release formulation of tacrolimus (Tacrolimus QD) was developed to allow once-daily dosing and to have similar safety and efficacy profiles to twice-daily tacrolimus (Tacrolimus BID). This study compared the pharmacokinetics (PK) and renal pathology by protocol biopsy in de novo living kidney transplant recipients treated with either low-dose Tacrolimus QD or Tacrolimus B...
