This research was conducted to determine the reproductive performance of sows that are kept intensively at the level of smallholder farming. The research method used was a direct interview with pig farmers in Kalasey Village. The data obtained were analyzed descriptively. The results showed a birth rate (litter size) of around 12 piglets, 110 days of pregnancy, 21 days of estrous cycles with 42 hours of estrus duration. With these results, it can be concluded that the reproductive performance of sows in the Kalasey Village is relatively good and according to normal standards.

Summary
The goal of raising pigs is to produce meat and make a profit. Feed, disease and management will affect the resulting production. The reproductive ability of pigs is very high compared to other livestock, which can produce many children at each birth. Skills in detecting estrus and the process of marrying pigs are key to the success of livestock production and productivity. Reproductive performance is a general description of the success of an enterprise in the livestock sector. The results of the study by Ohin [11] show that there is no difference in reproductive performance between Landrace and Duroc breeds. The pig population in North Sulawesi in 2018 reached 418,297 heads [2]. To increase the population and production of pigs, a description of the reproductive performance of livestock is needed. Namely to see how the reproductive performance of sows in the farms in Kalasey Village.
