Aflatoxicosis in Egyptian sheep 2- clinical chemistry and carcass quality

Abstract: Twenty eight Rahmani lambs aged 5 months old with an average live body weight 28.7 Kg were used in feeding trail to examine the ability of the row bentonite and aluminosilicate to detoxify aflatoxin in naturally contaminated concentrate feed mixture and berseem hay. Lambs were divided randomly into four equal groups. Group 1(G1), as control negative, fed on aflatoxin free ration; group 2 (G2) as a control positive on aflatoxin contaminated ration; Group 3, (G3), Fed on the eame aflatoxin contaminated ration but with 1.5% bentonite and Group 4 (G4), Fed also on the same aflatoxin contaminated ration but with 1.5% aluminosilicate. The feeding experiment lasted 126 days. Blood samples were collected 3 times during the experiment starting from the end of the 2nd month with one month interval peroid for clinical bichemical analysis. At the end of the experiment, 3 lambs from each group were slaughtered. In comparison with G1, the obtained results revealed that aflatoxin contaminated ration without clays (G2) significantly altered all tasted blood parameters in all tested periods, induced significant decrease in carcasses weight, and caused significant increase in liver and kidney weights of the slaughtered lambs. Also, higher levels of aflatoxin B1 and its metabolites was recorded in muscles, liver and kidney tissues of G2 slaughtered lambs in contrast to G1 lambs. The addition of both clays to the contaminated ration diminished the alteration caused by aflatoxin contaminated ration in all tested blood parameters as well as in both carcasses and organs weights of G3 and G4 lams in comparison with that of G2. Also the higher values for the residue of aflatoxin B1 and its metabolites which recorded in different tested tissues in G2 lambs were effectively reduced in tissues of G3 and G4 slaughtered lambs. The previous findings indicated that bentonite and aluminosilicate has high ability to detoxify aflatoxin, and the addition level of 1.5% of these clays to the contaminated ration of sheep can effectively provide a highly protection against many of the negative-toxic effects of aflatoxin on the growing lambs.
