卢氏绿壳蛋鸡育成期适宜能量水平的研究
|
摘要
试验旨在通过研究不同能量水平对卢氏绿壳蛋鸡育成期体尺、生长性能及屠宰性能的影响,得出其育成期能量的需要量。选用150只体重相近的8周龄卢氏绿壳蛋鸡,按能量水平(A组10.52 MJ/kg、B组10.90 MJ/kg、C组11.29 MJ/kg、D组11.70 MJ/kg、E组12.10 MJ/kg)随机分为5组(5个重复,每个重复6只鸡)。试验采取单因素试验设计,预试期1周,正试期10周。结果表明:不同能量水平显著影响卢氏绿壳蛋鸡育成期的胫长、胸宽和胸深(P<0.05)。D和E组的终末体重和平均日增重差异不显著(P>0.05),但均显著高于A、B和C组(P<0.05)。能量过高时(E组),终末体重和平均日增重又有所下降。不同能量水平对卢氏绿壳蛋鸡的屠宰性能影响显著(P<0.05)。在本试验条件下,日粮能量水平为11.70 MJ/kg时,更有利于提高卢氏绿壳蛋鸡育成期的生产性能和屠宰性能。
This experiment was conducted to investigate the effects of different dietary energy levels on body measurements, growth performance and slaughter traits of growing Lushi green-shell egg laying pullets, and to gain the energy requirement of pullets. A total of 150 Lushi green-shell egg laying pullets with similar weight aged 8 weeks were randomly allocated to 5 groups, each of which included 5 replicates of 6 pullets. Five experimental diets were formulated based on ME content of A(10.52 MJ/kg), B(10.90 MJ/kg), C(11.29 MJ/kg),D(11.70 MJ/kg) and E(12.10 MJ/kg). A single factor experimental design was adopted. The pre-trial period was one week, and the trial period was ten weeks. The results showed that different energy levels had significant influence on shank length, chest width and chest depth of Lushi green-shell egg laying pullets(P<0.05). There was no significant difference between group D and E on final weight and ADG(P>0.05), but both were significantly higher than group A, B and C(P<0.05). When the ME(group E) was excessive, the final weight and ADG decreased. Different energy levels had significant influence on slaughter traits(P<0.05). It is concluded that ME 11.70 MJ/kg in this study could improve the growth performance and slaughter traits of Lushi green-shell egg laying pullets during the growing period.
