  Background and Objective: Aflatoxins are among the top common courses of aflatoxicosis in poultry. In addition to the huge economic implications of aflatoxicosis to the poultry industry, aflatoxins are life-threatening to birds when present above the standard tolerable limit in poultry feed. Despite several reports on the levels of aflatoxin present in tested feed samples, natural cases of aflatoxicosis in poultry are rarely reported. The present study was conducted to report a natural case of aflatoxicosis in two different poultry farms where laying hens were fed with an aflatoxin contaminated feed. Materials and Methods: We collected a sample of poultry feed suspected to be contaminated with aflatoxins for analysis. Direct competitive ELISA using AgraQuant® total aflatoxin (TA) test kit was used to quantify the total aflatoxin level in the collected feed sample. Results: Laboratory analysis of the feed sample showed a high level of total aflatoxin of up to 320 ppb (parts per billion). This is 15 times above the FAO action point (20 ppb) for total aflatoxin in finished poultry feed. A post-mortem examination of the affected birds revealed typical lesions associated with aflatoxicosis. Interestingly, hens raised in a deep litter system showed more resistance to the same level of aflatoxin exposure when compared to hens raised in the cage system. Conclusion: We conclude that there is a surge in the natural cases of aflatoxicosis in poultry due to high level of aflatoxins in poultry feed, especially in developing tropical countries like Nigeria. We postulate that physical exercise could affect the rate of aflatoxin metabolism in poultry.

  Fifteen (15) nuliparous Savanna Brown does aged 6-8 months with a mean live weight of 9.55 kg were randomly allotted into five dietary treatments comprising of three animals per treatment. Five different diets with varying levels of flamboyant tree seed meal were fed as supplement at the rate of 0.50 kg/head/day. T1 which had no flamboyant tree seed served as control while diet T2, T3, T4 and T5 which served as the treatment diet had 25, 50, 75 and 100% flamboyant tree seed meal, respectively. The animals were managed semi-intensively. 5 mls of blood samples were collected via jugular vein puncture into well labeled EDTA bottles and were immediately placed in an ice-chest containing ice cubes and analyzed within 2 h of collection for blood glucose, protein and plasma urea. The average total blood glucose and protein were significantly (p<0.05) different with diets T1 and T2 recording higher values while plasma urea level did not differ significantly (p<0.05) among the treatment groups. All the values obtained were within the recommended normal range. It is therefore concluded that up to 100% level of inclusion of flamboyant tree seed meal in the diets of Savanna Brown does was not deleterious on the blood parameters.
