Stability of the Broiler Antibody Under Heat Stress Using Dry Rice

This study examines the impact of using dry rice, characterized by low calories and high resistant starch content, on broiler performance under heat stress conditions in Indonesia. Broilers face challenges related to stress, particularly heat stress, which can compromise their immunity. The research investigates the potential of resistant starch in dry rice to enhance broiler digestion performance and immunity. The experiment, conducted at Zakiyah Farm and the Laboratory of the Wates Veterinary Center, Yogyakarta, involved three treatments (T1, T2, and T3) with five replications each. Observed variables included water consumption, carcass weight, Packed Cell Volume (PCV), bursa fabricius weight, and Hi-Test Nd antibody levels. Results showed no significant impact on water consumption, carcass weight, and PCV across all treatments. However, a decrease in bursa weight in T1 and T3 indicated an increased level of stress. The lowest seropositive Hi-Test Nd values in T1 and T3 suggested that the use of dry rice through the sowing method might alleviate heat stress on broilers. In conclusion, this research emphasizes the potential of dry rice to maintain the stability of broiler antibodies under heat stress conditions, emphasizing the need for further exploration of alternative dietary components.
