饲粮钙水平对贵妃鸡生长性能、体尺性状及趾骨特性的影响
Influence of Dietary Calcium Level on Growth Performance, Body Measurements and Toe Quality of Princess Chickens
摘要
Abstract
This experiment was conducted to investigate the effects of different dietary calcium(Ca)levels on growth performance,body measurements and toe quality of princess chickens. A total of 240 1-day-old prin-cess chickens were randomly assigned to 5 groups with 6 replicates of 8 birds each,and were fed a corn-soy-bean diet(available phosphorus 0.51%)containing 0.65%(basal diet),0.80%,0.95%,1.10% and 1.30%of Ca,respectively. The experiment lasted for 49 days. The results showed as follows:1)dietary Ca level had a significant influence on growth performance(P<0.05). The average daily gain and average daily feed intake showed the broken-line and quadratic effects with the increasing of Ca level( P<0.05). But the leg paralysis occurrence and mortality were not significantly affected by the Ca level(P>0.05). 2)The dietary Ca level had significant influences on the percentages of leg muscle and abdominal fat(P<0.05)except for other carcass in-dices and meat quality. With the increasing of dietary Ca level,the percentage of abdominal fat was linearly de-creased(P<0.05),but the percentage of leg muscle tended to show a quadratic effect( P = 0.072). 3)The shank length showed the broken-line effects( P<0.05),while the body length and metatarsus circumference showed the quadratic effects(P<0.05)with the increasing of dietary Ca level. 4)Dietary Ca level had signifi-cant influences on the ash and Ca content in toe ash(P<0.05),which showed the quadratic effects with the in-creasing of dietary Ca level( P <0.05). In conclusion,average daily gain,average daily feed intake,body length,shank length,metatarsus circumference,toe ash and Ca content in toe ash are suitable for evaluating Ca requirement for princess chickens. The appropriate level of dietary Ca for princess chickens during the age of 1 to 49 days is recommended to be 1.10%(available phosphorus 0.51%).关键词
