摘要

本试验旨在研究羟基蛋氨酸螯合锰/锌替代产蛋鸡饲粮中无机锰/锌对产蛋鸡蛋壳品质及微量元素沉积的影响。试验采用单因子设计,共设3个组,羟基蛋氨酸螯合锰/锌分别替代基础饲粮中相应无机锰、锌水平的0、50%和100%。每个组6个重复,每个重复10只60周龄、体重相近的海兰褐蛋鸡,试验期60 d,分为2个阶段。结果表明:1)饲粮中不同添加形态的微量元素对产蛋率、平均蛋重、日产蛋量、料蛋比和破蛋率无显著影响(P>0.05);2)使用有机微量元素,在减少微量元素的添加量情况下,不影响蛋品质(P>0.05);3)饲粮中添加有机微量元素可以显著减少粪便中微量元素铜、锌和锰的排放量(P<0.05)。由此可见,在蛋鸡产蛋后期使用有机微量元素有提高产蛋率、日产蛋量和降低料蛋比的趋势;使用有机微量元素在减少微量元素使用量的情况下,降低了粪中微量元素的排放量。

Abstract

This experiment was conducted to study the effects of partial replacement of inorganic [manganese (Mn) and zinc (Zn)] by methionine hydroxy analog chelated Mn/Zn (Mn/Zn-MHA chelated) on egg shell quality and deposition of trace elements of laying hens. Three groups were arranged to investigate the effects of substituting the mixture of Mn/Zn-MHA chelated for the mixture of corresponsive inorganic trace elements with different levels of 0, 50% and 100%. A total of 180 Rohman laying hens (60-week-old) with similar body weight were divided into three groups randomly with six replicates per group and ten hens per replicate. The experiment lasted for 60 days with 2 phases. The results showed as follows: 1) adding different type of trace elements in diets didn't significantly affect laying rate, average egg weight, daily egg production, feed egg ratio and the broken egg rate (P>0.05). 2) Using organic trace elements could reduce the dosage of trace elements, no significant difference was observed in egg quality between groups (P>0.05). 3) Adding organic trace elements in diets could significantly reduce the fecal excretion of copper (Cu), Zn and Mn (P<0.05). In conclusion, it is possible that using organic trace elements in peak period can improve the laying rate, daily egg production and decrease the feed egg ratio. Moreover, Mn/Zn-MHA chelated can reduce emissions of trace elements in feces with low dosage.

Key words： methionine hydroxy analog chelated Mn/Zn; laying hens; egg shell quality; deposition of trace elements
