ABSTRACT Deoxynivalenol (DON), a mycotoxin synthesised by the Fusarium, is known to affect the growth of pigs. This effect can be attenuated with sodium meta-bisulphite (SBS). The aim of this study was to evaluate the effect of SBS with antioxidant blend on nutrient digestibility in pigs fed a diet contaminated naturally with DON. Six crossbred castrated pigs fitted surgically with single-T cannulas in the distal ileum received one of four barley-corn-soybean diets with or without SBS. After 8 d of feeding, faeces and ileal digesta were collected for 2 d. Apparent ileal digestibility (AID) of the dry matter (DM), energy, nutrients and DON, and apparent total tract digestibility (ATTD) of DM, acid detergent fibre (ADF), neutral detergent fibre (NDF), energy and DON were evaluated. The AID of phosphorus, calcium and some amino acids was increased (p < 0.05) in the DON diets whereas the ATTD of DM and energy tended to decrease (p = 0.064 and p = 0.071). SBS reduced the AID of DM, energy, ADF, ether extract, phosphorus and DON (p < 0.05) but had no effect on the ATTD of DM, energy, fibre or DON. These results show that DON improved the AID of some nutrients but tended to reduce the ATTD of energy, which could explain, although anorexia is the main effect of DON on live weight gain, the reported negative effect of DON on pig growth. Finally, SBS with antioxidant blend had reduced AID of some nutrients and intestinal absorption of DON.

脱氧雪腐镰刀菌烯醇和偏亚硫酸氢钠对生长猪养分消化率的影响

摘要 脱氧雪腐镰刀菌烯醇 (DON) 是一种由镰刀菌合成的真菌毒素,已知会影响猪的生​​长。这种影响可以用偏亚硫酸氢钠 (SBS) 减弱。本研究的目的是评估 SBS 与抗氧化剂混合物对饲喂天然受 DON 污染日粮的猪的营养消化率的影响。六头杂交去势猪在回肠远端通过手术安装了单 T 插管,接受了四种大麦 - 玉米 - 大豆饮食中的一种,有或没有 SBS。饲喂8 d后,收集2 d的粪便和回肠食糜。评估了干物质 (DM)、能量、营养素和 DON 的表观回肠消化率 (AID),以及 DM、酸性洗涤纤维 (ADF)、中性洗涤纤维 (NDF)、能量和 DON 的表观全消化道消化率 (ATTD) . 磷的助剂,DON 饮食中钙和一些氨基酸增加(p < 0.05),而 DM 和能量的 ATTD 趋于降低(p = 0.064 和 p = 0.071)。SBS 降低了干物质、能量、ADF、醚提取物、磷和 DON 的 AID(p < 0.05),但对干物质、能量、纤维或 DON 的 ATTD 没有影响。这些结果表明,DON 提高了某些营养素的 AID,但倾向于降低能量 ATTD,这可以解释,虽然厌食是 DON 对猪增重的主要影响,但据报道 DON 对猪的生长有负面影响。最后,含有抗氧化剂混合物的 SBS 降低了某些营养素的 AID 和 DON 的肠道吸收。05) 但对 DM、能量、纤维或 DON 的 ATTD 没有影响。这些结果表明,DON 提高了某些营养素的 AID,但倾向于降低能量 ATTD,这可以解释,虽然厌食是 DON 对猪增重的主要影响,但据报道 DON 对猪的生长有负面影响。最后,含有抗氧化剂混合物的 SBS 降低了某些营养素的 AID 和 DON 的肠道吸收。05) 但对 DM、能量、纤维或 DON 的 ATTD 没有影响。这些结果表明,DON 提高了某些营养素的 AID,但倾向于降低能量 ATTD,这可以解释,虽然厌食是 DON 对猪增重的主要影响,但据报道 DON 对猪的生长有负面影响。最后,含有抗氧化剂混合物的 SBS 降低了某些营养素的 AID 和 DON 的肠道吸收。
