Control of Oestrus and Ovulation in Cows
Although the methods and techniques that will be used to synchronize follicle growth and ovulation in the future may yet to be discovered, many tools that are needed may already exist. Once synchronous growth of a competent dominant follicle occurs, ovulation can be induced at a predictable time by applying drugs or hormones that induce LH release, or by administration of exogenous LH. Developm...
متن کاملRelationship between peri-oestrus progesterone levels and time of ovulation by echography in pigs and influence of the interval between ovulation and artificial insemination (AI) on litter size.
Two methods for the determination of ovulation were compared to one ultrasonography performed 5 times a day. Time of ovulation by echography was 40 +/- 5.8 h (mean +/- SD) after the onset of oestrus. Preovulatory LH rise (two blood samples per day) began near the onset of oestrus but, in our conditions, this parameter could not be used to predict ovulation. The basal level of progesterone (two ...
متن کاملIntrauterine artificial insemination of swine with different sperm concentrations, parities, and methods for prediction of ovulation
This study compared the reproductive performance of sows that were submitted to cervical artificial insemination (CAI) using concentrations of 3.5 x 10 spermatozoa per dose or intrauterine artificial insemination (IUAI) with 2, 1, or 0.5 x 10 spermatozoa per dose. Within all treatments, females were inseminated either after conventional estrus detection or after ultrasound-guided ovulation diag...

امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
15 صفحه اولsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
