摘要: A 50 day feeding trial was conducted with White Leghorn (WL) laying hens, 42 weeks old, to determine if of varying levels aflatoxin (AF), ochratoxin (OA) or their combinations has any effect on performance and egg quality parameters. Feeding T4, T7, T 8, 9 T10 caused significant reduction in feed intake hens. Hen productions were significantly reduced at all the toxins except 0.5 ppm AF. Maximum production noticed 2 4 AF OA, respectively. Average body weight not affected by toxin feeding. The efficiency terms net consumed per dozen produced higher both combinations. Feed consumption for 1 kg mass remained uninfluenced due whereas increase value same level OA combination (T9 T10), Various (1-4 ppm) two (T8, T9 T10) altered shape index eggs shell thickness (2 ppm), combination. Albumen index, Haugh Unit yolk unchanged incorporation diet. It is concluded that AF, either singly could depress significantly. parameters i.e. also affected. (Asian- Aust. J. Anim. Sci. 2003.
