概括

食子 (CS) 补充剂改善了日本长小鸟的体重增加. 对于生长和料效率来说,最佳的CS含量水平估计在21-35g/kg之间,这表明它作为自然生长促进剂的潜力.

科学领域:

动物科学动物科学
禽类的营养养
料添加剂料添加剂

背景情况:

日本的长是家禽肉的重要来源.
优化生长表现和尸体特征对于生产的经济可行性至关重要.
天然料添加剂越来越多地被探索为合成增长促进剂的替代品.

研究的目的:

为了评估食中子种子 (CS) 补充对日本长小生长和尸体特征的影响.
确定CS的最佳含量水平,以提高生长性能和料效率.
评估CS对母乳肉产量的影响.

主要方法:

这是一项完全随机的设计实验,对375只日本白幼 (7-28天) 进行.
进行了五种饮食治疗:0.0 (对照),10,20,30和40g/kg CS.
测量了生长表现 (体重增加,料摄入量,G:F比率) 和尸体特征. 使用回归分析来估计最佳的纳入水平.

主要成果:

随着CS补充,体重增加线性增加 (P=0.017).
随着CS水平的提高,料摄入量往往会下降 (P=0.133).
乳房肉的产量呈现了改善的趋势,随着CS纳入的增加 (P=0.073).
增长和料效率的最佳CS含量估计在21-35g/kg之间,乳房肉的产量在25-29g/kg之间.

结论:

食子种子补充剂有效地提高了日本的生长性能.
为了最大限度地提高生长和料效率,最佳含量水平大约是25-35g/kg的食.
子种子显示出作为自然生长促进剂的潜力,可以提高子生产效率.

关键词:

Cochran's Q Test

Cochran's Q Test

Cochran's Q Test is a nonparametric statistical test used to determine if there are potential differences in the outcomes of three or more related groups on a binary (yes/no) or dichotomous outcome. It is essentially an extension of the McNemar Test, which is limited to two related samples - Cochran's Q test can handle three or more related samples, making it more versatile in scenarios where subjects are measured under multiple conditions. The test statistic follows a Chi-Square...
