Energy values and metabolizability of lipid sources of plant and animal origin in the diet of Japanese quail

ABSTRACT The objective of this study was to determine the energy values and metabolizability of different lipid sources in the diet of Japanese quail at the laying phase. The quail were distributed in a completely randomized design with ten replications of seven poultry per treatment, totaling six treatments: basal feed (control) and basal feed containing 10% soybean oil, corn oil, canola oil, sunflower oil, and poultry fat. The values of nitrogen-corrected apparent metabolizable energy (AMEn) and the metabolizability coefficient (MC%) were evaluated. No significant difference was found between the different lipid sources for AMEn (kcal/kg) and MC (%). The value of metabolizable energy corrected for nitrogen for soybean oil was 8,790 kcal/kg; 8,773 kcal/kg for corn oil; 8,784 kcal/kg for canola oil; 8,788 kcal/kg for sunflower oil; and 8,681 kcal/kg for poultry fat in laying Japanese quail. The digestibility coefficients were 93.88% for soybean oil, 93.53% for corn oil, 93.32% for canola oil, 93.74% for sunflower oil, and 93.06% for poultry fat.

摘要 本研究以产蛋期日本鹌鹑为试验对象，旨在测定其日粮中不同油脂来源的能量值与代谢率。试验采用完全随机设计，每处理组设置10个重复单元，每个单元饲养7只鹌鹑，共设置6个处理组：基础日粮对照组，以及添加10%大豆油、玉米油、菜籽油、葵花籽油与禽油脂的基础日粮组。本试验测定了氮校正表观代谢能（nitrogen-corrected apparent metabolizable energy，AMEn）与代谢率系数（metabolizability coefficient，MC%）。结果表明，不同油脂来源的AMEn（单位：kcal/kg）与MC（%）均无显著差异。在产蛋期日本鹌鹑日粮中，大豆油的氮校正代谢能值为8790 kcal/kg，玉米油为8773 kcal/kg，菜籽油为8784 kcal/kg，葵花籽油为8788 kcal/kg，禽油脂为8681 kcal/kg。各油脂的表观消化率系数分别为：大豆油93.88%、玉米油93.53%、菜籽油93.32%、葵花籽油93.74%、禽油脂93.06%。
