Resumo
We evaluated the biostimulation and temporary weaning aiming follicular dynamics, conception rateand pregnancy rate in Nellore cows. Are used two groups of 75 cows. NESD: control without biostimulation andcalf at foot and BEDT56: biostimulation and temporary weaning for 56 hours. The interval between thebeginning of the treatment and emergency surge in days was 3.37 ± 0.50 for NESD and 3,40 ± 0,27 for BEDT56.The gap between the implant removal and ovulation in time was 60,85 ± 3,10 (NESD) and 66,75 ± 1,35(BEDT56). The larger diameter of the ovulatory follicle of the new follicular wave, cows with a diameter >8,0mm, was 12,1 ± 1,0 mm in NESD and BEDT56 15,2 ± 0,7 mm. The conception rate and pregnancy 37,3%(28/75) in NESD and 69,3% (52/75) in BEDT56. The association of biostimulation and temporary weaningincreases follicular development, conception rate and pregnancy rate in Nellore cows.(AU)
