Abstract

This experiment was conducted to investigate the effects of dietary benzoic acid on the growth performance, serum biochemical parameters, nutrient digestibility and digestive enzyme activities of jejunal digesta in weaner piglets. A total of 72 healthy weaner piglets (Duroc譒andrace譟orkshire, weaned at 24 days of age) with an initial body weight of (6.03?0.78) kg were randomly divided into 2 groups with 6 replicates (pens) per group and 6 piglets per pen. The piglets were fed a basal diet (control group) and the basal diet+5 000 mg/kg benzoic acid (benzoic acid group), respectively. The whole trial lasted for 42 days. The results showed as follows: compared with the control group, diets supplemented with 5 000 mg/kg benzoic acid significantly decreased the feed/gain during the whole trial period (P<0.05), and significantly increased calcium and triothyrone contents in serum on day 42 and the digestibility of dry matter, crude protein, ether extract, calcium, phosphorus, energy and ash (P<0.05 or P<0.01). Compared with the control group, diets supplemented with 5 000 mg/kg benzoic acid significantly increased the activities of trypsin, lipase, amylase, maltase, sucrase and lactase of digesta in jejunum on day 14 and activities of lactase and sucrase of digesta in jejunum on day 42 (P<0.05 or P<0.01). In conclusion, diets supplemented with 5 000 mg/kg benzoic acid can improve the growth performance, serum biochemical parameters, nutrient digestibility and digestive enzyme activities of digesta in jejunum of piglets.

Key words： benzoic acid; growth performance; nutrient digestibility; digestive enzyme activities; piglets
