Effects Of CAN On Adsorbing Hexachloridebenzene In The Diet Of Fishing Pigs

This work was carried out to estimate the effect of CAN on absorbing hexachloridebenzene (BHC) in corn-soybean diet of fishing pigs. Ninety-six fishing pigs which weighed 25. Okg were divided into 5 treatment groups, each of which included three replicates of eight pigs. The five dietary treatment were basal diet only(control, containingO. 05mg/kg), basal diet+0. 40mg/kg BHC+0. 5%CAN(T1), basal diet+0. 80mg/kg BHC +0.5% CAN(T2), basal diet+0. 40mg/kg BHC (T3), basal diet+0. 80mg/kg BHC (T4). Six pigs from treatment were selected according to live weight after 90d of feeding. Samples(liver, kidney, hair, fatty, muscle, cord, serum) were colected to determine the residual of BHC. The activities of GOP, GPT, ALP, TchE and the concentitions of CHL, TG, TP, SUN, Ca, P were analysed.. Liver GST, SOD enzyme activities and MDA concentition were assied.The results of BHC residual showed that addition of 0. 5%CAN to the diets containing either 0. 45mg/kg BHC or 0. 85mg/kg BHC , The residuals in liver, kidney, hair, fatty, muscle, cord and serum all significently decreasd (P<0.01).The results from feeding trial showed that addition of 0. 5%CAN to the diets containing either 0.45mg/kg BHC or 0.85mg/kg BHC significently increased ADG by 12. 2%(P<0. 05), 10. 5%(P<0. 05) ; F/G reduced by 12.6% (P<0. 05), 10.7% (P<0. 05), respectively.The results of tissue organ relative weight showed that the kidney relative weight of pigs fed on CAN-treated diet including 0. 45mg/kg or 0. 85mg/kg BHC were decreased by 15.2%(P<0.01) and 14. 3%( P<0. 05) ,respectively.The results from biochmical parameters analysis indicated the addition of CAN to the 0. 45mg/kg or 0. 85mg/kg BHC-supplement diet significently decreased the activities of GPT, TchE, ALP (P<0.01), significently increased the activities of GST, SOD and the concentition of MDA in liver(P<0. 01).
