据流行病学调查,黄曲霉毒素(AFT)是致癌性的,鉴于其广泛存在于一般牲畜饲料中并可引起农畜的中毒症,因而由组织转移到肉中引起人的饮食性致癌作用是可能的。为了弄清AFT从饲料转移到猪组织中的程度,作者用加有已知量的AFT B_1、B_2、G_1和G_2的饲料,喂猪21天,屠宰后,对各种组织进行检查。试验是将来源于两窝体重各为24.5～26.3kg的8只杂交猪,随机分成对照与试验两组。两组饲料相同,只是在试验组每公斤饲料中分别加有662、273、300和285μg的AFT B_1、
According to epidemiological investigations, aflatoxins (AFT) are carcinogenic and due to their widespread presence in animal feedstuffs and their toxic effects on livestock and poultry, the carcinogenic effect of dietary transfer from the tissue to the human diet is possible. To understand the extent of AFT transfer from feed to pig tissue, the authors fed pigs in known amounts of AFT B_1, B_2, G_1, and G_2 for 21 days and after slaughtering, examined various tissues. The experiment is from the two bales each weighing 24.5 ~ 26.3kg 8 hybrid pigs were randomly divided into control and test two groups. The two groups of feed were the same except that 662, 273, 300 and 285 μg of AFT B_1 were added to the test group per kg of feed,
