The Effect of Different Floor Levels on the Microclimate Conditions and Physiological Responses of Broilers in Open Houses

Abstrak

The purpose of this study was to determine the differences in microclimate conditions and physiological responses of broiler chickens in a multi-tier open house system. The research material used 150 broiler of the Cobb strain consisting of 15 pens on each tier, with each pen containing 5 birds. The method used was an experimental method with 2 treatments: T1 = lower tier and T2 = upper tier. Data were analyzed using an Independent Samples T-test and Mann-Whitney test according to the data distribution. The observed variables included temperature, humidity, heat stress index (HSI), heart rate, respiratory rate, panting, and rectal temperature. The results showed that temperature, humidity, and HSI were not significantly different (T>0.05) between tiers. The difference in tier level had a significant effect on heart rate, respiratory rate, and panting (T<0.05), with higher values observed in the upper tier, while rectal temperature was not significantly different (T>0.05). It is concluded that the difference in tier level in an open house system increases physiological heat stress in broiler chickens, as indicated by the increase in heart rate, respiratory rate, and panting.
