Effects of the adsorption of bamboo-carbon and bamboo vinegar to the diets contaminated by DON on serum free amino acids content of weaned piglets

【Objective】This experiment was conducted to study the effects of adding bamboo-carbon and bamboo vinegar to the diets contaminated by deoxynivalenol (DON) on serum free amino acids content of weaned piglets.【Method 】A total of 28 crossbred (Duroc×Landrace×Large white) weaned piglets with an average body mass of (12.10±1.12) kg were randomly assigned to 4 groups, with 7 replicates per group and 1 piglet in each replicate. The 4 groups were as follows: control group (a basal diet), DON group (the basal diet+DON), bamboo-carbon group (the basal diet+DON+2% bamboo-carbon), bamboo vinegar group (the basal diet+DON+1% bamboo vinegar). The experimental period lasted for 37 d. 【Result and conclusion】 1）On the 15th day of the experiment, there was no significant difference between the experiment group and control group (P>0.05), besides 3MHis in DON group and bamboo-carbon group significantly decreased by 39.06%,40.62%（P<0.05）. 2）On the 30th day of the experiment, compared with the control group, Ile, Val, Cys, Hyp, 3MHis in DON group were significantly decreased by 26.60%, 25.96%, 73.38%, 44.61%, 26.09%（P<0.05）as compared to the control group, Cys, 3MHis in bamboo-carbon increased by 173.17%, 8.82%（P>0.05）, respectively; Hyp, 3MHis Cys in bamboo vinegar group increased by 55.96%（P<0.05）, 26.47%（P<0.05）, 170.73%（P>0.05）, respectively. 3）On the 37th day of the experiment, compared with the control group, Hyp in DON group significantly increased（P<0.05）; His, 1MHis in bamboo-carbon group significantly decreased（P<0.05）; His, Orn, 1MHis in bamboo vinegar group significantly decreased（P<0.05）; Hyp, Gln in bamboo vinegar group significantly increased（P<0.05）. Dietary supplementation with 2% bamboo-carbon or 1%bamboo vinegar could alleviate a part of serum free amino acids content, with a decrease or a significant decrease by DON challenge in weaned piglets. The weaned piglets have certain tolerant ability to DON with the time, dietary supplementation with bamboo-carbon and bamboo vinegar can give appropriate adjustment.
