摘 要:在相同的饲养管理条件下,观测了白羽、黑羽、花羽番鸭的生长性能,以筛选生长性能最佳的番鸭品系。白羽、黑羽、花羽公番鸭14、28、42、56、70、84、98日龄的平均日增重分别为9.0、9.4、9.7g,35.8、35.6、35.9g,58.4、58.0、59.3g,62.9、68.6、65.9g,46.9、47.6、42.5g,28.1、17.9、19.9g,7.1、7.5、7.4g;14、28、42、98日龄品系间差异不显著(P>0.05);56、70、84日龄品系间差异显著(P<0.05)。母番鸭56日龄平均日增重,白羽、黑羽、花羽分别为33.5、39.4、33.2g,品系间差异显著(P<0.05)。公母间的平均日增重,14、28日龄差异不显著(P>0.05),42、56、70、84、98日龄差异极显著(P<0.01)。公、母番鸭平均日增重最大值分别出现在56、42日龄。白羽番鸭适合于作杂交利用及配套系的父本。White,black,and piebald native muscovy ducks were studied under the same feeding conditions to select the best strain of muscovy duck.The average daily gains of male at 14,28,42,56,70,84,98 days old of white,black, and piebald mnseovy ducks were 9.0,9.4,9.7 g;35.8,35.6,35.9 g;58.4,58.0,59.3 g;62.9,68.6,65.9 g;46.9,47.6,42.5 gs 28.1,17.9,19.9g;7.1,7.5,7.4g,respeetively. Among the three strains at 14,8,42,98 days old there were not significant different (P〉0.05),and at 56,70,84 days of age there were different significantly(P〈0.05).The average daily gain of female at 56 days old of white,black,and piebald muscovy ducks were 33.5,39.4,33.2 g,respectively.There were different significantly (P〉0.05)among between the three strains.The average daily gains between male and female at 14,28 days of age were not different significantly (P〉0.05),which at 42,56,84,98 days old were different highly significantly (P〈0.01).The maximum average daily gains of male and female muscovy ducks were at 56 and 42 days old,respectively,White muscovy duck is suitable for male parent in utilization of heterosis and crossbreeding.
