Improved reproductive efficiency is the outcome of herd management and could involve a decision to choose between artificial insemination (AI) and natural service (NS). The objective of the present study was to determine the time of ovulation and pregnancy rate (PR) following timed AI (TAI) and NS, and frequency of TAI of two different management systems in oestrus synchronized Kedah-Kelantan (...

Buffalo reproduction is considerably affected by late maturity, poor oestrus symptoms and long postpartum periods. This study was undertaken to evaluate the efficiency of Eazi Breed controlled internal drug release (CIDR), an intravaginal progesterone-releasing device, in relation to oestrus and fertility. Five hundred true anoestrus buffalo cows, in the age group 4-6 years in 10 villages of Dh...

We hypothesize that insemination with fresh extended semen will improve the AI pregnancy rate due to its prolonged longevity in female reproductive tract compared to frozen thawed semen. The objective of this trial was to determine the effect of fresh and frozen semen on fixed-time AI pregnancy rate in beef cows synchronized with progesterone based CO-Synch protocols and inseminated at differen...

The number of large innovations per year has been increasing rapidly since the start of the new millennia (Figure ??). From Hadoop and big data, to internet of things, to millennial startups, to visualization, to deep learning, each new innovation has left an undeniable mark on society, and ultimately, the world. Although the database community may not have led the charge in these innovations, ...

 Though conception rates within 2 weeks of Eazi-BrEEd CIDR removal were lower for treated cows (27.7% vs 36.2% for controls, P < 0.083), overall pregnancy rates did not differ between treatment groups (P = 0.32). [Conception can be reduced by: 1) an older, unknown-aged egg being ovulated after an extended progesterone period; 2) vaginitis, so cleanliness and proper insertion technique are impo...

For assessing the impact of melatonin pre-treatment in summer anestrous Murrah buffaloes on subsequent reproductive activity a fixed time artificial insemination (FTAI) protocol, 83 were subcutaneously inserted 2x4 mm size absorbable (MT) implants (18 mg/50 kg b wt) at base left ear and 38 used as non-implanted controls. On day 35 post-MT, treatment control group subjected to FTAI protocol (Ovs...

The present study was aimed to evaluate the efficiency of estradiol cypionate, benzoate and gonadotropin-releasing hormone during fixed-time artificial insemination (FTAI) protocols in multiparous Murrah buffaloes. A total 35 buffaloes were used between September November 2021 subjected a synchronization protocol. On day 0, insertion an intravaginal progesterone device (CIDR, 1.38 g) made with ...

Yearling Bos indicus × Bos taurus heifers (n = 410) from three locations, were synchronized with either the Select Synch/CIDR+timed-AI (SSC+TAI) or 7-11+timed-AI (7-11+TAI) treatments. On Day 0 of the experiment, within each location, heifers were equally distributed to treatments by reproductive tract score (RTS; Scale 1-5: 1 = immature, 5 = estrous cycling) and body condition score. The 7-11+...

The world currently faces significant hydrologic changes associated with global climate change, such as in precipitation patterns, rising surface temperature, and increases the frequency intensity of floods droughts, which will affect design capacity operating characteristics dams/reservoirs. This brings new challenges to current water management strategies. research is aimed create, apply, pro...

Reproductive performance was evaluated in non-lactating crossbred ewes to which were administered the exogenous GnRH and PMSG. The ewes were randomly allocated in three treatment groups (n=40).After accurate detection of estrus and 2 hours prior to mating, 2.5 mL of distilled water and 2.5 mL of GnRH were injected intramuscular to each ewe of the first (control) and second group, respectively. ...
