چکیده انگلیسی


- Behavioral and ovulatory features of estrus-induced dairy goats are reported.
- An alternative AI technique with goat in a standing position is described.
- The AI technique provides a high degree of intrauterine semen deposition.
- The AI technique described allows quick and safe semen deposition.
- The AI technique described facilitates a good pregnancy rate.

This study evaluated reproductive features and role of Flunixin-Meglumine at timed artificial insemination (AI), using a new technique of standing position with cervix immobilization. In Experiment 1, 10 goats (n = 5 nulliparous [Null] and 5 pluriparous [Plu]) were evaluated after estrus induction by recorded reproductive parameters to define the ideal time for AI. In Experiment 2, goats were artificially inseminated 51-54 h after sponge removal with frozen-thawed semen. At AI, 1 mL saline (CONTROL; 18 Null and 14 Plu) or 50 mg Flunixin-Meglumine (FLUNIXIN; 15 Null and 18 Plu) was administered i.m. Location of semen deposition was recorded for both groups. In Experiment 1, all sexual behavior and ovulatory parameters were similar between Null and Plu for estrus response and ovulation (100%), interval from sponge removal to ovulation (∼64.2 h), largest ovulatory follicle diameter (∼6.6 mm), and number of ovulations (∼2.0). In Experiment 2, pregnancy rate was superior (P < 0.01) for CONTROL (62.5%; 10 Null and 10 Plu) than FLUNIXIN (30.3%; 3 Null and 7 Plu) goats. Regardless of the treatment, intrauterine AI was more frequent (P < 0.01) in Plu (100.0%; 32/32) than in Null (69.7%; 23/33) goats. Moreover, AI was more time-consuming (P < 0.01) in Null (44 ± 37 s; 4-139 s) than in Plu (21 ± 19 s, 4-78 s) goats. Therefore, administration of Flunixin-Meglumine at the time of AI adversely affected pregnancy rate. High rates of intrauterine cervical penetration were obtained, achieving good pregnancy rates in goats not receiving Flunixin-Meglumine.
