Preventing pigs such as wild pigs (Sus scrofa) from accessing the farm can be blocked by installing fences or repellent to make them feel reluctant to access the farm. Most wild pigs were captured to prevent crop damage and incidence of African swine fever (ASF). Still, there is a limit to capturing them due to the rapid population growth. A study was conducted using "To Nature" repellent with an active ingredient of Methyl anthranilate (MA) to assess the effectiveness of MA as a pig repellent and determine its effect on feeding behavior and production performance. A total of eight female pigs [(Landrace x Yorkshire) x Duroc] were randomly arranged and used in the experiment for five weeks. Each treatment was replicated four times, having one pig in every replication. The feeders' position with MA repellent was shifted weekly with a ratio of 0.25% and mixed with 10kg of feed. The number of approaches of pigs to the feeder was monitored daily using a full HD CCTV 5-megapixel camera. A significantly lower number of approaches, feed intake, and total time spent feeding in the feeding trough was recorded from the feeder with MA repellent mixed in the diet. Regression analysis revealed a positive relationship in the feeding behavior of pigs in the feeder mixed with MA repellent in the diet. Therefore, 0.25% MA repellent can be used as pig repellent without adverse effects on the production performance of growing pigs.
