Synchronization of estrus and fertility in Zebu beef heifers treated with three estrus synchronization protocols

Theriogenology, 1999
The effects on estrus and fertility of 3 estrus synchronization protocols were studied in Brahman beef heifers. In Treatment 1 (PGF protocol; n=234), heifers received 7.5 mg, i.m. prostianol on Day 0 and were inseminated after observed estrus until Day 5. Treatment 2 (10-d NOR protocol; n = 220) consisted of norgestomet (NOR; 3 mg, s.c.

Induction and synchronization of estrus in dogs

Theriogenology, 2005
Indications for estrus induction in the bitch include missed breeding opportunities or conception failure, the treatment of primary or secondary anestrus and synchronization of ovulation for embryo transfer programs. Reported methods for canine estrus induction include the use of synthetic estrogens (diethylstilbesterol), dopamine agonists ...

Estrus synchronization in sheep with synthetic progestagens

Tropical Animal Health and Production, 2009
Sixteen female sheep of Degua breed were assigned to receive either the full dose of norgestomet ear implant and injectable solution containing norgestomet and estradiol valerate (n = 8) or half the dose (n = 8). The ear implants were removed in both groups on day 12.

Synchronization of estrus in cattle for embryo transfer

Theriogenology, 1977
Abstract Two groups of donors (31 animals) receiving 2,000 to 3,000 IU of PMSG followed by 30 to 33 mg of prostaglandin F2α-THAM salt 48 hours later showed an average interval to estrus of 44 ± 2.7 and 51 ± 5.7 hours after prostaglandin treatment. Three groups of donors (32 animals) receiving the above treatment plus 500 μg estradiol 32 to 38 hours ...

Synchronization of estrus in beef cattle

Theriogenology, 1978
Abstract A series of 11 trials involving 735 heifers and 425 cows were conducted in an effort to improve synchronization of estrus using a 9-day progestin implant and an injection of estrogen and/or progestin. Ninety-five percent of 42 heifers treated during the first 5 days of the estrous cycle with an ear implant containing 6 mg of 17α-acetoxy-11β ...

A review of synchronization of estrus in postpartum cattle.

Journal of Animal Science, 1990
Estrus has been synchronized in cattle with progestogens, prostaglandins (prostaglandin F2 alpha and its analogues), progestogen-estrogen combinations and progestogen-prostaglandin combinations. Progestogens administered for 14 to 20 d are effective in synchronizing estrus; however, fertility at the synchronized estrus is subnormal.
