Abstract

The protective effects of various feed supplements against the harmful effect of ochratoxin A on egg production and sexual maturation of two-weeks old Plymouth Rock female chicks designed for laying hens were studied. A significant protective effect of the feed additives or materials: water extract of artichoke (WEA), sesame seed (SS), Roxazyme-G (RG) and l-beta phenylalanine (PHE) against the suppressive effect of ochratoxin A (OTA) on egg production of laying hens was found. A similar protection was also seen on the toxic effect of OTA on various internal organs of the same hens. A significant protection was found against the decrease of the weight or the quantity of eggs as well as against the delay of the beginning of the laying period of chicks, both of which were provoked by ochratoxin A. These protective effects were strongest in chicks treated with SS or WEA, but were slightest in chicks treated with l-beta PHE.

摘要

研究了各种饲料添加剂对蛋鸡用两周龄布罗米奇母雏鸡生产和性成熟的黄曲霉毒素 A 有害影响的保护作用。研究发现，饲料添加剂或物质水芹提取物（WEA）、芝麻（SS）、Roxazyme-G（RG）和 L-β-苯丙氨酸（PHE）对黄曲霉毒素 A（OTA）抑制蛋鸡产蛋的作用有显著的保护作用。对 OTA 对同一母鸡各种内脏器官的毒性作用也有类似的保护作用。发现对雏鸡体重或蛋量的减少以及产蛋期开始的延迟有显著的保护作用，这两者都是黄曲霉毒素 A 引起的。在 SS 或 WEA 处理的雏鸡中，这些保护作用最强，但在 L-β-PHE 处理的雏鸡中，这些保护作用最弱。
