Cortisol and Postpartum Luteal Function in Cattle
The present study investigated serum cortisol in response to postpartum ovarian resumption and luteal function. Postpartum ovarian resumption was detected based on a rise in progesterone (P4) concentrations during three weeks after calving. Twenty two Holstein cows in a semi-closed dairy farm in Qena city, Egypt were used. The study was carried out from late March to early June; the period char...
متن کاملEstrous activity detection device in mammals.
Control of estrus is essential for the efficiency of any breeding program in farm animals, artificial insemination, hand mating and prediction of parturition dates. The present study is providing new evidence about determination of silent estrus in Damascus does. Since many D. does do not show any interest toward the male across seasons compared with spontaneous estrus detected by buck goat (BG...
متن کاملLuteal blood flow and luteal function
BACKGROUND Blood flow in the corpus luteum (CL) is associated with luteal function. The present study was undertaken to investigate whether luteal function can be improved by increasing CL blood flow in women with luteal phase defect (LFD). METHODS Blood flow impedance in the CL was measured by transvaginal color-pulsed-Doppler-ultrasonography and was expressed as a resistance index (RI). The...
متن کاملInducing Early Estrous and Ovulatory Cycles
The goal of any breeding operation is to maximize reproductive efficiency and minimize the cost of producing live offspring. The reproductive performance of broodmares can be assessed by determining pregnancy and foaling rates for a season or, preferably, for each cycle. Mean pregnancy rates per cycle are 50% to 60% under current management conditions. However, the rates vary widely depending o...
متن کاملLuteal phase support in intrauterine insemination cycles
Intrauterine insemination (IUI) treatment aims to increase the rate of conception by increasing the chances that the maximum number of healthy sperm reach the site of fertilization. IUI with controlled ovarian stimulation is frequently used in assisted reproduction practice. Although widely used, the efficacy of luteal support in IUI remains controversial. In this article, we aimed to review wh...
