Optimizing Broiler Production in Urban Area Using Liquid Premix

High temperature in narrow areas can cause heat stress in broiler. In this condition, broiler performance will decrease, so efforts are needed to deal with these negative impacts. One of them is by providing premix as a supplement. This study aims to find the best dose of commercial premix containing vitamins C, E, and micronutrients to improve the performance of broilers reared in areas with ambient temperatures above thermoneutral. The study used a total of 160 Cobb strains day old chick (DOC) with 4 treatments and 5 replications. Each replication consisted of 8 chicks. The treatment was a premix dose consisting of P0 (0 mL); P1 (0.1 mL); P2 (0.15 mL); and P3 (0.20 mL). The ambient temperature was 29-30 °C and 70% humidity. The observed data were the body weight, the average body weight gain, feed consumption, water consumption intake, and feed conversion ratio (FCR). The data c were analyzed by completely randomized design. Results of this study showed that the use of premix as a feed supplement did not significantly different (P>0.05) on the broiler performance. The average body weight gain at 28 days was 1689 grams, 132 grams of feed intake, 320 mL of drinking intake, and FCR 1.55. The use of premix with dose up to 0.20 mL as a feed supplement for broiler in narrow areas has not shown a significant improvement in performance.
