Abstract

Effect of growth period at about 15 and 25 kg body weight on amino acid ileal digestibility in young pigs

Highlights

There is limited information on digestion and absorption of nutrients in the small intestine of young pigs given natural feeds, there have been extensive studies on piglets between 7 and 35 d of age (Wilson and Leibholz, 1981a,b,c)
The authors found that substitution of milk protein by soyabean protein reduced digestibility of nutrients
A detailed study showed that the apparent digestibility of dry matter, N and amino acids (AA) to the ileum of ILEAL AA DIGESTIBILITY IN YOUNG PIGS

Summary

Introduction

There is limited information on digestion and absorption of nutrients in the small intestine of young pigs given natural feeds, there have been extensive studies on piglets between 7 and 35 d of age (Wilson and Leibholz, 1981a,b,c). Piglets given soyabean protein increased with increasing age of pigs, while no changes in the digestibility was observed in milk-fed piglets. In an investigation on the digestibility of carbohydrates, protein and fat in the small intestine of 8-12 week-old piglets with ileal cannulas, Gdala et al (1997) found no significant changes in digestibility during four weekly periods when pigs were fed two diets with a relatively high dietary fibre content: cereal-soyabean meal diet or cereal-pea-soyabean meal-rapeseed cake diet.
