中文摘要:黄曲霉毒素B1(AFB1)是常见的饲料污染物,给家禽性能及产品质量带来不利影响。本研究将600只7日齡鹌鹑按完全随机化设计,随机分成八个实验组,每个实验组5个重复,每个重复15只鹌鹑。实验处理包括给7-35日齡的鹌鹑提供两种水平的AFB1(0和2.5mg/kg)及四种水平的黑种草(NS) (0、0.5、1.0及1.5%日粮)。研究表明,NS作为一种生物解毒剂可以相对减轻AFB1对鹌鹑的负面影响。
外文摘要:Aflatoxin B-1 (AFB(1)) is a common feed contaminant that adversely affects bird performance and product quality. A total of 600 7-day-old quail chicks were randomly allotted to eight experimental groups in a completely randomized design with five replicate pens and 15 quails per pen. Experimental treatments including two levels of AFB(1) (0 and 2.5mg/kg) and 4 levels of Nigella sativa (NS) (0, 0.5, 1.0 and 1.5% of diet) were offered from 7 to 35days of age to quail chicks. Although feeding of AFB(1) impaired gain (G) and feed conversion ratio, dietary NS increased G (p<0.05). Relative weight of bursa of Fabricius increased with incremental levels of NS (p<0.05). AFB(1) decreased the size of heart, but incremental levels of NS increased the relative weight of heart (p<0.05). The liver hypertrophy was observed in birds receiving AFB(1) (p<0.05). The birds in AFB(1) group had smaller testes than other groups (p<0.05). Hematocrit value in birds fed AFB(1) was lower than that in other groups (p<0.05) and incremental levels of NS increased blood hematocrit (p<0.05). Amount of malondialdehyde (MDA) in meat samples of the birds fed AFB(1) was higher than those did not receive toxin but incremental levels of NS decreased the MDA concentration in affected birds (p<0.05). AFB(1) suppressed the humoral immunity of the birds while NS augmented the antibody titres against sheep red blood cell and Newcastle disease virus antigens (p<0.05). AFB(1) decreased lactic acid bacteria (LAB) and spore-forming bacteria (SFB) but increased Escherichia coli (E.coli; p<0.05). However, NS increased LAB and SFB but decreased the E.coli populations (p<0.05). This study revealed that NS as a biological detoxifier could relatively attenuate the negative effects of AFB(1) inquails.
