Abstract

The aim of this experiment was to evaluate the effects of dietary crude protein (CP) level on growth and development and serum biochemical indexes of Rugao yellow chickens aged from 3 to 8 weeks. Five hundred and forty 2-week-old Rugao yellow chickens were randomly assigned to 3 groups with 6 replicates per group and 30 chickens per replicate. The CP levels of each group were 17.50%, 19.00% and 20.50%, respectively. The experiment lasted for 6 weeks. The results showed as follows:1) with the dietary CP level increased, the body weight of hens at 5 and 8 weeks of age and the average daily weight gain (ADG) of hens aged from 3 to 5 weeks of age, 6 to 8 weeks of age and 3 to 8 weeks of age decreased linearly (P<0.05), while the average daily crude protein intake (ADCPI), ratio of crude protein to gain (CPCR) and ratio of feed to gain (F/G) of hens aged from 3 to 5 weeks of age, 6 to 8 weeks of age and 3 to 8 weeks of age, as well as the ratio of metabolic energy to gain (MECR) of hens aged from 6 to 8 weeks of age and 3 to 8 weeks of age increased linearly (P<0.05). 2) With the dietary CP level increased, the relative length of ileum increased linearly (P<0.05), while the relative weight of jejunum and relative length of duodenum showed an increased firstly and then decreased quadratically (P<0.05). 3) With the dietary CP level increased, the ratio of length and diameter of tibia and femur to weight increased linearly (P<0.05), while the diameter and strength of femur decreased linearly (P<0.05). 4) With the dietary CP level increased, the contents of glucose (GLU) and low-density lipoprotein cholesterol (LDL-C) in serum increased linearly (P<0.05), while the serum alanine aminotransferase (ALT) activity decreased linearly (P<0.05). In conclusion, under the experimental condition, low dietary CP level (17.50%) can meet the requirement for growth and development of Rugao yellow chickens, and the body weight, ADG, F/G, CPCR, MECR and serum biochemical indexes show advantage.
