Evaluation of a herbal extract in the diet on the productive behavior of heat-stressed pigs
The exposure of pigs to heat stress (HS) affects the integrity of intestinal epithelia, compared to thermal neutral (TN) pigs, partially due to overproduction of free radicals. Herbal extracts (HE) from Capsicum spp., Pipper nigrum y Zingiber officinales possess antioxidant activity. The effect of adding this HE to the diet was analyzed on performance of 42 pigs (27±3 kg). The treatments were: TN-C, TN pigs with control diet, TN-P, pigs with control diet plus 0.02% HE; HS-C, HS pigs with control diet; and HS-P, HS pigs with control diet plus 0.02% HE. The experiment consisted of two periods; in period 1, all pigs were adapted to the control diet during 8 days under TN conditions, followed by a 7-day experimental period. Daily weight gain and feed intake were higher (P <0.05), and feed conversion ratio tended (P<0.10) to improve in HS-HE pigs compared to HS-C pigs. In conclusion, adding HE to the diet can improve some productive parameters in pigs exposed to HS conditions.
