RESUMO
tThe objective was to evaluate the influence of the largest follicle diameter (DMF) in the TAI D10pregnancy rate of Nelore PO cows. 36 females were used, divided into two groups (≤ 10mm and> 10mm) in thefollowing protocol. In the D0 was introduced intravaginal P4 implant (DIB® 1g; Zoetis) and applied 2mL BE(Gonadiol®; Zoetis) IM. In D8 was removed the implant and applied 300 IU (1.5 mL) of eCG (Novormon®;Zoetis) and 2.0 mL of PGF2a (Ciosin®, Zoetis). In the D9 was applied 1mL BE (Gonadiol®; Zoetis) and 24hafter TAI was made. Females were subjected to ultrasound examination by transvaginal the D10 formeasurement of DMF. Pregnancy diagnosis was performed 30 days after TAI. Data were evaluated using SASsoftware (2009) and the pregnancy rate was compared using the chi-square test (P < 0.05). The pregnancy ratefor the group with DF ≤10 mm was 16.6% (6/36) and> 10 mm was 27.7% (10/36) with no statistical difference(P > 0.05).(AU)

The aim of the study was to evaluate the influence of follicular population (PF) in the TAI of D0 in thepregnancy rate of Nelore PO cows. 36 cows were used, divided into two groups (≤ 10 and> 10 follicles) weresubmitted to the following protocol. In the D0 was introduced intravaginal P4 implant (DIB® 1g; Zoetis) andapplied 2mL BE (Gonadiol®; Zoetis). In D8 was removed the implant and applied 300 IU (1.5 mL) of eCG(Novormon®; Zoetis) and 2.0 mL of PGF2a (Ciosin®, Zoetis). In the D9 was applied 1mL BE (Gonadiol®;Zoetis) and 24h after TAI was made. The cows were subjected to ultrasound examinations Transvaginal in D0 toPF score. Pregnancy diagnosis was performed 30 days after TAI. The data were analyzed by SAS software(2009) and the pregnancy rate was compared using the chi-square test (P < 0.05). The pregnancy rate for PF≤10 group was 54.55% and the PF group> 10 was 28.57% in the D0, with no statistical difference (P > 0.05).(AU)
