Adoption of automated monitoring devices (AMD) affords the opportunity to tailor reproductive management according cow's needs. We hypothesized that a targeted (TRM) would reduce use hormones while increasing percentage cows pregnant 305 d in milk (DIM). Holstein from 2 herds (n = 1,930) were fitted with an AMD at 251.0 ± 0.4 gestation. Early-postpartum estrus characteristics (EPEC; intense heat index ≥70; 0 minimum, 100 maximum) multiparous evaluated 40 (herd 1) or 41 2) DIM and EPEC...

Abstract The objectives of this experiment were to evaluate the effects supplementation Nellore ( Bos indicus ) cows with β‐carotene + vitamins A D3 E biotin on body condition score (BCS), oestrus, pregnancy, and foetal morphometry. Lactating n = 497) from two herds balanced for BCS calving period [early (EC); late (LC)] assigned randomly to: Control 251)—supplementation a mineral supplement; SUP 246)—supplementation supplement fed control (150 mg/day) vitamin (40,000 IU/day) (5000 (300 (20...

Abstract The aim was to evaluate the effects of beta-carotene and vitamins (A, D3, E biotin) on reproductive performance grazing Nellore cows calving in different moments. A total 497 multiparous (5.68 ± 0.11 parities) were homogeneously divided 4 paddocks (Brachiaria brizantha spp.) according BCS (2.8 0.27), following a completely randomized design 2 x factorial arrangement, being factors: moment [CM = early October (EO; 1st-15th) or late (LO; 16th-31st)]; supplementation (SUP): control...
