摘要

本研究旨在评价1200 μg/kg黄曲霉毒素B1 (AFb1)、黄曲霉毒素B2 (AFb2)和三种真菌毒素吸附剂对肉鸡生产行为、新城疫抗体滴度、血液化学和组织病理学病变的影响。192只1日龄鸡随机分为4个处理,每个处理3个重复,每个处理16只鸡,试验42 d。评估治疗:T1 =基础饮食;T2 =基础饲粮中AFb1和AFb2含量1200 μg/kg;T3 =基础饲粮中AFb1、AFb2和吸附剂1.200 μg/kg (A);T4 = 1200μg / kg的饮食AFb1和AFb2吸附(B)。结果表明,鸡使用吸附到1200μg / kg的AFb1和AFb2、改进其食品conversion(简历)、增加证券抗体为纽卡斯尔(那么)21和42天,disminuyo aspartato transaminasa (AST) 21天、增加其albumina (A)和总proteinas (PT) 21和42天。尿酸(ua)在42天下降。但无论治疗如何,鸡的组织病理学病变都是相似的。上述浓度下的黄曲霉毒素B1和B2和吸附剂(A)与上述剂量下的黄曲霉毒素联合使用42 d可降低CV、增加TAN、降低AST、降低AU、提高A和PT,而吸附剂(B)则不能。本研究的目的是评价1200 μg/kg黄曲霉毒素B1 (AF B1)、黄曲霉毒素B2 (AF B2)和三种吸附真菌毒素对肉鸡生长性能、抗纽卡斯尔抗体滴定剂、血液化学和组织病理学损伤的影响。= =地理= =根据美国人口普查,这个县的面积为,其中土地面积为,其中土地面积为。评估治疗:T1 =基础饮食;T2 =基础饲粮,含1200 μg/kg AFbj和AFb2;T3 =基础饲粮,含1200 μg/kg AFb1和AFb2加吸附剂(A);T4 =的健怡with 1200μg / kg of AFb1和AFb2 plus adsorbent (B)。结果表明,接种禁饮食adsorbent (A)和1200μg / kg of AFb1和AFb2,改善其feed conversion (FC),增加了its antibody titers Newcastle (nwt) at 21和42天,decreased The aspartate transaminase (AST) at 21 days and it增加its albumin (A)共计protein (TP) at 21和42天。尿酸(UA)在42天内减少。不管治疗方法如何,鸡的组织病理学病变是相似的。结论,B1和B2 at a和多元化of the aflatoxins 1200μg / kg and the adsorbent (a)可以减少FC,增加nwt for 42天,减少了AST,减少非盟和提高a和TP,然而this was not the case for adsorbent (B) when is combined with the aflatoxins In the level事先提过。

Comportamiento productivo y toxicosis en pollos de engorde alimentados con aflatoxinas B1, B2 y tres adsorbentes de micotoxinas
