Abstract

The objective of this study was to evaluate the impact of the determination methods (free feeding [FF] and tube feeding [TF]) on the available energy of ingredients (wheat, paddy, and brown rice). A total of 101 adult Hy-Line Brown roosters (35 weeks old) with an initial body weight of 2.72 ± 0.21 kg were used, in which 96 roosters were randomly assigned to the FF group and TF group, and the remaining five birds were selected to determine the endogenous energy loss. Each group consisted of 12 dietary treatments. In the FF group, each diet treatment comprised 2 replicates with 2 birds per replicate and 4 replicates with 1 bird per replicate for each diet in the TF group. The 12 dietary treatments included a basal diet (BD) and 11 test diets, in which wheat, paddy, and brown rice replaced 30% corn, soybean meal, and wheat bran in the BD. The experiment was performed three times. There was a significant effect of source on apparent metabolizable energy (AME) and true metabolizable energy (TME) in paddy (p < 0.05). Results showed that AME in wheat, paddy, and brown rice measured by the FF method were greater than those values gained by the TF method (p < 0.05). The average AME and TME values were 3537, 3140, and 3893 kcal/kg dry matter (DM) and 3555, 3163, and 3933 kcal/kg DM for wheat, paddy, and brown rice, respectively, measured by the FF method. The means of AME and TME evaluated by the TF method were 3270, 2988, and 3764 kcal/kg DM and 3642, 3357, and 4135 kcal/kg DM for wheat, paddy, and brown rice, respectively. In conclusion, the determination method has a considerable effect on available energy, and the TF method underestimates the AME of ingredients.

通过自由采食和管饲法测定的公鸡体内小麦、稻谷和糙米的代谢能值比较
本研究的目的是评估测定方法(自由采食[FF]和管饲[TF])对原料(小麦、稻谷和糙米)可利用能量的影响。研究共使用了 101 只初始体重为 2.72 ± 0.21 kg 的成年海线褐公鸡(35 周龄),其中 96 只被随机分配到 FF 组和 TF 组,其余 5 只用于测定内源性能量损失。每组包括 12 种日粮处理。在 FF 组中,每种日粮处理包括 2 个重复,每个重复 2 只;在 TF 组中,每种日粮处理包括 4 个重复,每个重复 1 只。12 种日粮处理包括基础日粮(BD)和 11 种试验日粮,其中小麦、稻谷和糙米取代了基础日粮中 30% 的玉米、豆粕和麦麸。实验共进行了三次。在稻谷中,来源对表观代谢能(AME)和真实代谢能(TME)有显著影响(p < 0.05)。结果表明,用 FF 法测得的小麦、稻谷和糙米的表观代谢能高于用 TF 法测得的数值(p < 0.05)。用 FF 方法测定的小麦、稻谷和糙米的平均 AME 和 TME 值分别为 3537、3140 和 3893 千卡/千克干物质(DM),以及 3555、3163 和 3933 千卡/千克 DM。用 TF 法评估的小麦、水稻和糙米的 AME 和 TME 平均值分别为 3270、2988 和 3764 千卡/千克 DM,以及 3642、3357 和 4135 千卡/千克 DM。总之,测定方法对可利用能有相当大的影响,TF 法低估了原料的 AME。
