Abstract

In order to explore the relationship between feather and early development of body weight in fast- and slowfeathering groups of Dahen broiler, the body weight and feather growth rate (covert, primary and tail feather) of 1-10 weeks old Dahen broilers were measured and analyzed. The results showed that there was no significant difference in body weight between fast feathering and slow feathering broilers aged 1-10 weeks; Before 4 weeks of age, the main wing feathers of fast feathered chickens were significantly longer than those of slow feathered chickens (isometric slow feathering, inverted slow feathering, unexplained slow feathering) (P < 0.05 or P < 0.01), and the difference gradually decreased with the increase of age, but there was no significant difference at the end of brooding; At the age of 10 weeks, the overlying wing feathers of the inverted and equal length slow feathered chickens were significantly longer than those of the fast feathered and unexplained slow feathered chickens (P < 0.05); Before 2 weeks of age, the main wing feather of fast feathered chicken was significantly longer than that of slow feathered chicken, the main wing feather of isometric slow feathered chicken was significantly longer than that of inverted slow feathered chicken and unexplained slow feathered chicken (P < 0.05), and the main wing feather of inverted slow feathered chicken was significantly longer than that of other three phenotypes (fast feathered, isometric slow feathered and unexplained slow feathered chicken) (P < 0.05 or P < 0.01); The tail feathers of fast feathered chicken and slow feathered chicken were significantly longer than that of slow feathered chicken at the same week of age. There was no significant difference in the length of tail feathers among the three different phenotypes of slow feathered chicken; The results showed that the growth of wing feather before 2 weeks old could be used as an auxiliary method for fast and slow feather identification of Dahen broiler.
