- Abstract
The purpose of this study is to explore the effect of adding Roselle in the diet on the production and blood biochemical parameters of laying hens in high temperature season. Hibiscus sabdariffa Linnaeus, also known as Roselle, is a cash crop with antioxidant properties. It is expected that Roselle can reduce the effects of heat stress in laying hens in summer. It is expected that Roselle can reduce the effects of heat stress in laying hens in summer. Add 0.1% and 0.2% Roselle to the feed, start the test for eight weeks at a temperature higher than 28°C, record the egg yield daily, and check the blood biochemical parameters such as ALP, AST, ALT and blood cholesterol every two weeks. The analysis results indicated that in the second week of the test, the ALT of the 0.1% Roselle group was significantly lower than that of the control group (P < 0.05), but there were no significant differences in other blood biochemical parameters and egg yield. According to the test results, the effect of Roselle on alleviating the heat stress of laying hens in summer does not seem to be high. If the feed cost permits, we can try to increase the amount of Roselle and carry out further discussion in the future.
