Reproductive performance of fixed-time artificial insemination in heifers supplemented with a homeopathic complex

For this study, ½ blood nelore × aberdeen angus heifers (n = 40; 14 months) were divided into two groups: control (n=20; 310 kg) and pró-cio 304 kg). for group, 20g of homeopathic product (pró-cio®, real h, campo grande, brazil) was supplied together with corn eighteen days prior (d-18) to the beginning fixed-time artificial insemination protocol (ftai). on d0, all females received an intravaginal p4 device 2 mg be. d5, afc assessed by ultrasound collected amh dosage. d8, removed; 300 iu ecg, 0.530 cloprostenol sodium 0.5 ec administered; estrus-identifying adhesive fixed at tail insertion diameter dominant follicle (df) measured. d10, inseminated, estrus manifestation preovulatory (pof) d20, cl area measured flow using doppler ultrasound. data analyzed student, mann-whitney or friedman test. rates heat expression, ovulation, score fisher’s exact test pregnancy rate binary logistic regression model (p ≤ 0.05). there no difference in dosage > group had greater diameters df (9.94 ± 0.42 mm) pof (11.61 0.56 than controls (df: 7.72 0.34 mm pof: 9.91 0.37 mm), as well a larger (3.26 0.26 versus 2.35 0.16 cm2) higher mean vascularization (3.06 2.26; p < significant 0.05) between conception groups. supplemented showed follicular end ftai better scores compared group.
