Objective: This study aims to evaluate the effect of providing concentrate at different times on success artificial insemination in limousin crossbred cow. The material used cows as many 45 cows, 15 each treatment, cattle between 1,5-6 years old, (BCS) 4-6 (standard 1-9). Methods: research method uses experimental field trials. Data analyzed Completely Randomized Block Design (RCBD), grouping based body weight (BW). Analyzed by ANOVA continued Duncan Multiple Range Test (DMRT). Treatment T0: grass + Bio ATP, T1: 14 days before oestrus and 7 after estrus ATP T2: ATP. Results: result show that DM consumption T0 (7,74 kg), T1 (12,54 kg) T2 (12,56 CP (0,62 (0,72 (0,69 TDN (4,32 (5,23 (5,17 kg). NRR1 86,67%, 60%, 73,33%, NRR2 60% 66,67%. CR treatment (66,67%), (33,33%) (26,67%). 80%, 66,67% dan 40%. Conclusions: conclusion this is using has a lower percentage pregnancy 40% without 80%.
