Fertility response in postpartum anoestrus buffaloes (Bubalus bubalis) using modified Ovsynch based timed insemination protocols
BACKGROUND AND AIM Suboestrus constitutes the largest factor responsible for poor reproductive efficiency in buffaloes. Therefore, oestrus synchronization (OS) and fixed-time artificial insemination (AI) is considered an alternative approach to enhance reproductive efficiency in buffaloes. Thus, the present study was carried out to study the efficacy of modified Ovsynch protocol with fixed time...
متن کاملComparison of Pregnancy Rates after Timed Artificial Insemination in Ovsynch, Heatsynch and CIDR-Based Synchronization Protocol in Dairy Cows
The objective of this study was to compare the effects of three different estrus synchronization protocols on the pregnancy rates of lactating dairy cows. Group 1 (Ovsynch protocol; n= ) animals received 20 μg GnRH on day 0, 500 μg PGF2α on day 7 and 20 μg GnRH on day 9; Group 2 (Heatsynch protocol; n= ) received 20 μg GnRH on day 0, 500 μg PGF2α on day 7 and an injection of 1 ml estradiol cypi...

15 صفحه اولSynchronization of Bos Indicus-influenced Cattle for Timed Artificial Insemination
Developing successful methods for synchronizing estrus and ovulation in cattle has been a major research interest for at least the last 35 yr. Early objectives focused on the control of the corpus luteum (CL) and artificial insemination (AI) relative to estrus. Ultimately, the goal has been to achieve precise synchronization of ovulation so that cattle can be inseminated without regard to estru...
متن کاملApplication of timed artificial insemination protocols to grazing Japanese black cattle with long open period.
To investigate the viability of timed artificial insemination (TAI) protocols in grazing Japanese Black cattle with long open period, ovarian status and progesterone and estradiol-17 beta profiles of the animals during the protocol were monitored. In 1998, prosta-glandin F(2a) (PG) was administered to 36 animals seven days after GnRH injection. Three out of the 36 animals were inseminated after...
