| Summary: | The experiment was conducted to study the effects of hexachlorocyclohexane (HCH) on growth performance, approach to the mechanism of effects by determining indexes of serum and hormone parameters. Seventy-two pigs, with equal number of barrows and gilts, the same genotype (Duroc × Landrace × Large White), were randomly assigned to three groups receiving the same basal diet, adding to 0, 0.4, 0.8 mg·kg<sup>-1</sup> HCH respectively for 90 days. This experiment was conducted to investigate the effect of HCH on Growth performance and Serum characteristics of growing/finishing pigs. The results indicated that the average daily gain (ADG) and feed conversion rate (F/G) in growing/finishing pigs were not significantly affected by HCH. However, at groups exposed to 0.4 mg·kg<sup>-1</sup> and 0.8 mg·kg<sup>-1</sup> HCH in diet, Serum T3 was increased by 49.9% and 41.7% (P<0.05), serum ALT activity was elevated by 11.2% (P>0.05) and 26.9% (P< 0.01), AKP activity was increased by 19.7% and 23.5% (P<0.01), serum Superoxide dismutase (SOD) was decreased by 10.05% and 14.35% (P<0.05) respectively. Serum Catalase (CAT) activity with 0.8 mg· kg<sup>-1</sup> HCH was decreased significantly by 14.21% (P<0.05). These indicated that HCH led to the turbulence of hormone metabolism and the somatic lesion. |
