Abstract
The present investigation was undertaken to study the protective actions of
seabuckthorn (SBT) seed oil and glucomannan (GM) in aflatoxin (AF) treated broiler chicks.
A total of 210, day old broiler chicks were used for studying the growth performance,
biochemical parameter and antioxidant status for the period of 4 weeks. The seabuckthorn
seeds oil was collected, SBT oil was fed orally to the broiler chicks @ 0.5 ml/kg bwt. and 1.0
ml/kg bwt. GM was mixed with the feed @ 1g/ kg whereas, AF was added @ 400ppb. The
AF treatment significantly (P<0.05) reduced weight gain and increased FCR. The SBT oil as
well as GM significantly (P<0.05) improved the growth performance. AF treatment produced
a significant (P<0.05) decrease in total serum proteins, albumin, globulin, cholesterol,
triglycerides and HDL and significant (P<0.05) increase in AST, ALT, ALP, LDH and total
serum billirubin. However, SBT oil as well as GM significantly (P<0.05) restored these
biochemical parameters to control levels. In aflatoxin treated groups the malondialdehyde
(MDA) level of liver, kidney and blood were significantly (P<0.05) increased whereas GSH,
Catalase, SOD and GPx levels were significantly (P<0.05) decreased, while there was no
significant (P>0.05) change in these parameters were found following only SBT oil
administration. The combined dietary supplementation of SBToil+AF and GM+AF produced
significant (P<0.05) decrease in lipid peroxidation and an increase GSH, catalase, SOD and
GPx level of liver, kidney and blood respectively than that of AF treated groups. The
histopathological lesions in the liver were severe in AF treated group and were least severe in
SBToil+AF followed by GM+AF groups and there were no lesions in only SBT oil alone
treated groups. On the basis of growth performance, biochemical parameters, antioxidant
activity and histology of the liver tissues, it is be concluded that oral supplementation of
seabuckthorn oil @ 0.5 ml/kg bwt. has provides protection against aflatoxicosis in broilers.
