Effects of Compound Acidifiers on Growth Performance and Intestinal Microbial Communities of Weaned Piglets
摘要
Abstract
The study was conducted to evaluate bacterial inhibition activity and acid-binding capacity of three acidifiers constituted of lactic acid, citric acid, malic acid, tartaric acid and phosphoric acid. To study the effect of acidifiers as antibiotics alternative on growth performance and intestinal bacterial communities, 96 weaned piglets (DurocxLandraeexYorkshire) were allocated to four dietary treatments in a randomized complete block design.The dietary treatments were control group including antibiotics, treatments of A, B and C without antibiotics, but adding acidifier A, B and C, respectively. The result showed that pathogenic bacteria Escherichia coli, Salmonella and Staphlococcus aureus were inhibited by acidifier A, B and C diluted in water at 0.25%, respectively. The three acidifiers inclusion in the diet at 1.25 kg/t significantly decreased the acid-binding capacity and pH value of feed (P<0.05). There were no significant difference in feed intake, average daily gain and feed to gain ratio among the control and treatments with acidifier A or C (P>0.05). The total number of DGGE bands and Shannon index of diversity, H' were significant higher in pigs fed the diet containing acidifier than that in control pigs with antibiotics, but with no significance (P>0.05).关键词
