    The objective of this study was to determine the effects of timely injections of flunixin meglumine (FM) or vaginal application of prostaglandin E2 (PgE(2)) on pregnancy, fertility, fecundity, and prolificacy rates in Saanen goats. One hundred and sixty-three nonlactating Saanen does were treated with a flugestone acetate (20 mg)-containing intravaginal sponge for 12 days. They also received eCG (400 IU) and a PGF(2 alpha) analogue (50 mu g) 10 days after progestagen priming. Does detected in estrus were mated and assigned randomly to one of three treatment groups. The PgE(2) group (N = 40) received PgE(2) (2.5 mg) intravaginally 15 days after mating. The FM group (N = 54) received flunixin meglumine (total dose, 100 mg) intramuscularly 15 days after mating. Flunixin meglumine was administered at 9:00 AM. Animals in the control group (N = 69) received no treatment. Pregnancy was diagnosed using transrectal ultrasonography (B-mode at 8 MHz) 30 days after mating. The pregnancy rate was significantly greater (P < 0.01) after 30 days in goats treated with PgE(2) and also in the control group than in those treated with FM (67.5%, 59.4%, and 42.5%, respectively). The pregnancy rate did not differ between the PgE(2) and the control group. The pregnancy and fertility rate were lowest in the FM group compared with the other groups. There was no significant difference in the prolificacy rate among experimental groups. In conclusion, our results showed that FM administration during a late luteal phase is detrimental to early pregnancy in goats. (C) 2014 Elsevier Inc. All rights reserved.

    Estrous Synchronization with Used CIDR-G Devices in Ewes During Non-Breeding Season
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2009) Gungor, Orsan; Ozyurtlu, Nihat; Pancarci, Suekrue Metin; Kaya, Mehmet; Zonturlu, Abuzer Kafar; Oral, Hasan; Cetin, Yunus
    The objective of this study was to investigate the efficacy of used controlled internal drug release devices (CIDR-G) on estrous synchronization in ewes. This investigation was conducted in 58 fat-tailed ewes during the non-breeding season. Ewes were divided in to four groups. In Group I, CIDR-G devices were inserted to vagina for 12 d (CIDR group). In Group II, previously used CIDR-G devices were inserted into the vagina for 12 d (U-CIDR). After the intravaginal devices had been removed 500 IU equine chorionic gonadotropin (eCG) was injected intramuscularly (i.m.) into ewes of the CIDR and U-CIDR groups. Ewes in Group III (eCG group), 500 IU eCG was injected im. Ewes in Group IV, served as control and received an injection of 3 mL 0.9% NaCl ( C Group). None of the control ewes expressed estrus. It was found that, 13/15 (86.67%), 10/15 (66.67%) and 1/13 (7.69%) ewes expressed estrus in CIDR, U-CIDR and eCG groups, respectively. The pregnancy rates in the CIDR, U-CIDR and eCG groups were 8/15 (53.33%), 9/15 (60%) and 1/13 ( 7.69%) at first breeding, respectively. The interval from eCG application to onset of estrus was 42.6+/-1.01, 40.13+/-1.35 and 74 h in the CIDR, U-CIDR and eCG groups, respectively. Average progesterone (P4) levels during P4 treatment were 3.28+/-0.28 and 2.62+/-0.14 ng/ml in the CIDR and U-CIDR groups, respectively. It is concluded that, CIDR-G that have been previously used for 12 d could be used for the synchroniation of estrus in ewes during non-breeding season.
