Effect of Naturally Contaminated Feed with Aflatoxins on Performance of Laying Hens and the Carryover of Aflatoxin B1 Residues in Table Eggs

Eu3+‐labeled IgG‐based time‐resolved fluoroimmunoassay for highly sensitive detection of aflatoxin B1 in feed

“…Aflatoxins (AFs), toxic secondary metabolites, are mainly produced by Aspergillus species, A. flavus or A. parasiticus , including AFB 1 , AFB 2 , AFG 1 and AFG 2 . AFs are regarded as one of the most harmful contaminants in feed, due to their carcinogenic, hepatotoxic, teratogenic and mutagenic adverse effects toward animals . AFB 1 is one of the most toxic compounds, identified as a group 1 carcinogen and a key factor causing liver cancer by the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) .…”

Changes in the regulation and activity of glutathione redox system, and lipid peroxidation processes in short‐term aflatoxin B1 exposure in liver of laying hens

“…The result of the present study showed that short‐term aflatoxin B1 exposure did not have any effect on feed intake, absolute and relative liver weight, probably due to short period of investigation. In long‐term experiments with laying hens, AFB1 caused marked feed refusal and increased liver weight (Aly Salwa & Anwer, ).…”

Evaluation of total aflatoxin, nitrate and nitrite levels in layer feed samples of companies producing their own feed in Edincik and Bandırma province of Turkey

“…Although it generally takes relatively high levels to cause mortality, low levels can be detrimental if poultry have fed the contaminated feed for a long time. Laying hens generally can tolerate higher levels than young birds, but levels should still be less than 50 mg kg À1 (Yaling et al 2008;Salwa and Anwer 2009). In laying hens, the effects of exposure to AF include (1) a dose-dependent decrease in egg production and egg quality and (2) increased susceptibility to salmonellosis, candidiasis and coccidiosis (Celik et al 1996;Oliveira et al 2002).…”

“…In laying hens, the effects of exposure to AF include (1) a dose-dependent decrease in egg production and egg quality and (2) increased susceptibility to salmonellosis, candidiasis and coccidiosis (Celik et al 1996;Oliveira et al 2002). One must pay special attention to the use of contaminated corn in layer rations, because eggs are used as human food and aflatoxin metabolites have been found in egg yolks (Salwa and Anwer 2009).…”
