不同日龄樱桃谷鸭生长性能及肉品质测定
Growth Performance and Meat Quality of Cherry Vally Duck at Different Ages
摘要
Abstract
The aim was to clarify the changes pattern in meat quality of Cherry Valley Duck at different ages,which provides scientific basis for determining the reasonable slaughter age.In this research,Cherry Valley Duck was selected as experimental materials,growth performance,normal meat quality and nutrient content of muscle were determined at the age of 28,38,42 and 45 days.As a result,body weight,breast weight,leg weight and the sheering force of breast muscle and leg muscle was lowest at the age of 28 days;and no significant differences were observed in the weight and sheering force of leg muscle at the other 3 ages.Besides same trend of changes was found in the protein content of breast muscle and leg muscle at all ages,which were shown to rise first and then fall.The protein content of breast muscle differed had significant difference among four ages and it reached highest at the age of 38 days.We found same trend of changes in fat content,which fell early,however,fat content of leg muscle had significant difference at four ages and the fat content of breast muscle differed from each other at the age of 28,38 and 45 days.In conclude,the meat quality of Cherry Valley Duck achieved its highest at the age of 42 days and slaughtering earlier or later will affect the deposition of muscle nutrients.关键词
