Four groups (each of 8 laying hens plus one cock) were offered commercial laying mash contaminated with 100 ppb of aflatoxins, citrinin, patulin or uncontaminated (control) for 6 weeks. The mycotoxin-contaminated diets led to some significant changes in egg characteristics and composition such as ash and calcium contents of the egg shell. The noticeable changes including also the relative weights of adrenal glands. Blood profile reflected too alterations (P greater than 0.05) in urea content and activity of both glutamic oxaloacetic transaminase and alkaline phosphatase as well. The mycotoxins affected significantly moisture and fat contents of the red muscle and protein content, texture and percentage of lean meat in both types of muscles (red and white). Patulin toxicosis was responsible for the strongest alterations in moisture, fat and vitamin A contents of the laying hen's liver and for the lowest calcium content of egg shell besides the shape alteration of the eggs. Laying hens fed on aflatoxin-contaminated diet produced hatched chicks with higher weight (P less than or equal to 0.05) than those from the controls. Citrinin residues were 10 ppb in the fresh muscles and egg yolk and 6 ppb in egg white.
将四组(每组8只产蛋母鸡加1只公鸡)分别投喂被100 ppb黄曲霉毒素、桔霉素、展青霉素污染的商品蛋鸡配合饲料或未受污染的饲料(对照组),为期6周。受霉菌毒素污染的日粮导致蛋的特性和组成出现一些显著变化,如蛋壳的灰分和钙含量。显著变化还包括肾上腺的相对重量。血液指标也反映出尿素含量以及谷氨酸草酰乙酸转氨酶和碱性磷酸酶活性的改变(P>0.05)。霉菌毒素显著影响了红肌的水分和脂肪含量以及两种肌肉(红肌和白肌)的蛋白质含量、质地和瘦肉百分比。展青霉素中毒导致产蛋鸡肝脏的水分、脂肪和维生素A含量变化最为明显,除了蛋的形状改变外,还导致蛋壳钙含量最低。饲喂受黄曲霉毒素污染日粮的产蛋鸡所产的孵化雏鸡体重高于对照组(P≤0.05)。新鲜肌肉和蛋黄中的桔霉素残留量为10 ppb,蛋清中为6 ppb。
