Relationships between blood biochemical indices and egg-laying performances in muscovy ducks

WANG Chang kang, LI Ang, ZHENG Nen zhu(College of Animal Science, Fujian Agriculture and Forestry University, Fuzhou, Fujian 350002, China)  
In order to provide a scientific basis for early selection, egg laying performances of muscovy ducks were recorded individually by abdominal palpation method. 60 female muscovy ducks of 56 weeks old were divided into high, medium, low groups by egg production, 20 ducks in each group. Nine blood biochemical indices were measured at the age of 56 weeks, and the relationships between blood biochemical indices and egg laying performances were investigated. The results showed: (1) No significant correlation between serum GOT, AKP, LDH, TG, CHOL or LDL C and egg laying performances was found ( r =0.008-0.210). (2) GPT had a significant negative correlation with the age of first laying (AFL) ( p 0.01 ), a slight negative correlation with the body weight at first laying (BW1) ( p 0.05), and a significant postive correlation with the egg production at the age of 43 weeks (EN 43) or 56 weeks (EN 56). (3) There was a significant correlation between TP and EN 56 ( p 0.05), while no correlation was obsersed between TP and other egg laying performances. (4) HDL C had a significant postive correlation with AFL ( p 0.01) or BW1 ( p 0.05), a significant negative correlation with EN 43 or EN 56 ( p 0.01).
