Title: Effects of Microencapsulated Compound Acidifier on Acidity and Development of Gastrointestinal Tract in Weaning Piglets
Abstract:The effects of different types of compound acidifiers (encapsulated and non-encapsulated) in maize-soybean basic diets on acidity and development of the gastrointestinal tract in weaning piglets were ...The effects of different types of compound acidifiers (encapsulated and non-encapsulated) in maize-soybean basic diets on acidity and development of the gastrointestinal tract in weaning piglets were investigated in this study. 64 28-day-old weaned Landrace×Yorkshire hybrid piglets with average weight of (7.00±0.10) kg were selected and grouped into four treatments with four pigs (half boars and half sows) in each repeat of four repeats in each treatment based on single-factor test design principles, and the pre-test period was 3 days but the test period was 35 days. The results showed that compared with acid-free diet group, encapsulated compound acidifier could reduce pH of stomach and intestinal in weaning piglets significantly (P0.01), while Test group 1 could also increase the relative weight of stomach and intestinal in piglets significantly (P0.05). Compared with non-encapsulated acidifier, encapsulated compound acidifier could greatly decrease pH in jejunum and ileum of weaning piglets (P0.05) or relative weight of stomach in piglets (P0.05), while Test group 1 could also enhance the relative weight of intestinal in piglets significantly (P0.01). In addition, encapsulated compound acidifiers significantly increased the ratio between the villus height and crypt depth of jejunum (P0.01). Accordingly, the microencapsulated compound acidifier in diets of weaning piglets can promote the development of gastrointestinal tracts for piglets by reducing pH of gastrointestinal tracts.Read More
