Abstract

Objective: This study aimed to investigate effects of apparent metabolizable energy (AMEn) levels in diets on productivity, fat deposition, and biochemical parameters of Woorimatdag1 (WMD1) breeder pullets.

Methods: A total of 240 four-week-old WMD1 breeder pullets were divided into four dietary groups with five replicates (12 birds per replicate). These groups had the following dietary energy levels: standard ME (SME), SME-200, SME-100, and SME+100 (diets containing 2,800, 2,600, 2,700, and 2,900 kcal AMEn/kg, respectively). These pullets were provided with diets and water ad libitum until 16 weeks old.

Results: Weight gain was significantly (p < 0.05) higher in SME-100, SME, and SME+100 groups than in the SME-200 group. SME+100 and SME groups exhibited significantly (p < 0.05) improved feed conversion ratio compared to the SME-200 group. Laying ages of 30% egg production occurred significantly (p < 0.05) earlier in SME-100, SME, and SME+100 groups than in the SME-200 group. SME and SME+100 groups had significantly (p < 0.05) higher liver fat (%) than the SME-200 group. Additionally, the SME+100 group had higher (p < 0.05) abdominal fat (%) than other groups. However, blood parameters were not significantly different among dietary groups.

Conclusion: SME-100 (2,700 kcal AMEn/kg) might be suitable for improving productivity and fat deposition of WMD1 breeder pullets.

日粮能量水平对 Woorimatdag1 种小鸡生产率、脂肪沉积和生化指标的影响。

研究目的本研究旨在探讨日粮中表观代谢能（AMEn）水平对 Woorimatdag1（WMD1）种小蓝耳鸡生产性能、脂肪沉积和生化指标的影响：将 240 只四周龄的 WMD1 种小鸡分为四个日粮组，每组五个重复（每个重复 12 只鸡）。这些组的日粮能量水平分别为：标准 ME（SME）、SME-200、SME-100 和 SME+100（日粮中的 AMEn 含量分别为 2800、2600、2700 和 2900 千卡/千克）。这些小鸡在16周龄前自由采食日粮和饮水：SME-100、SME和SME+100组的增重明显高于SME-200组（P < 0.05）。与 SME-200 组相比，SME+100 组和 SME 组的饲料转化率明显提高（p < 0.05）。与 SME-200 组相比，SME-100、SME 和 SME+100 组 30% 产蛋率的产蛋日龄明显提前（p < 0.05）。SME 和 SME+100 组的肝脏脂肪（%）明显高于 SME-200 组（p < 0.05）。此外，SME+100 组的腹部脂肪（%）也比其他组高（p < 0.05）。结论：SME-100（2,700 千卡）和 SME+100 组的血液指标没有明显差异：结论：SME-100（2,700 千卡 AMEn/千克）可能适用于提高 WMD1 代种鸡的生产性能和脂肪沉积。
