Abstract

This study aimed to determine the optimal concentration of mulberry leaf powder (MLP) supplementation and to evaluate the impact of different seasons on the growth performance, carcass characteristics, and blood lipid levels of Pradu-Hang-Dam chickens. One-week-old chickens were assigned to three groups: a control group (without MLP) and two groups receiving diets supplemented with 0.5% and 1.5% MLP, respectively, over a 10-week period. The results indicated that during the cool season, the control group exhibited the highest feed intake, average daily gain, and superior carcass characteristics (P < 0.05). In the rainy season, chickens supplemented with 1.5% MLP achieved the highest feed intake, while those supplemented with 0.5% MLP showed the highest average daily gain and the lowest feed conversion ratio (P < 0.05). Furthermore, the 1.5% MLP group demonstrated superior carcass characteristics compared to the control group during the rainy season (P < 0.05). Analysis of blood lipid metabolism revealed that the group supplemented with 0.5% MLP during the cool season had the lowest levels of triglycerides, cholesterol, and high-density lipoprotein. In conclusion, the cool season is the most favorable for raising Pradu-Hang-Dam chickens in Thailand. Additionally, supplementing diets with at least 0.5% MLP during the rainy season can improve growth performance, carcass characteristics, and blood parameters.
