Abstract

Artificial insemination in dairy cows is for improving genetic quality and replacement so that high pregnancy success is needed. This research was conducted on a smallholder farm in the Pujon sub-district, Malang Regency, Indonesia. The materials used were 100 cows, 100 in AI using a single dose of BCS 2.5–4 (with a range of 1–5), had given birth. In carrying out the research, the cows have shown signs of heat were injected with Bio ATP. Prior to AI, the estrus character was observed, which was distinguished by the color of the vulva, which was divided into evenly red, uneven red, and pale. The vulvar temperature was distinguished from < 38 ℃ and > 38 ℃. Cervical mucus = cervical mucus was abundant and thick, cervical mucus was abundant and watery, cervical mucus was slightly thick and cervical mucus was slightly watery. Swelling of the vulva, consisting of a swollen vulva and a non-swollen vulva. After one cycle, NRR-1 was observed and not in heat, it was considered pregnant after 2 months of pregnancy examination using ultrasound (USG). The results showed that the highest non-return rate and conception rate values in FH crossbreds were in the red vulva color, 33 cows (33%) and 30 heads (20%) were not evenly distributed. Temperature > 38OC as many as 62 animals (62%) and 38 animals (38%), in the amount of thick mucus 31 (31%) and 19 individuals (19%), vulvar swelling was swollen 68 (68%) and 43 (43%).
