Technical Abstract: In this chapter, the anatomy and histology as well as the growth and ontogeny of the digestive system in the pig are reviewed briefly. The developmental patterns of porcine gastric, pancreatic and intestinal enzymes and gastric acid during the fetal, postnatal and postweaning periods are also described. Physiological and nutritional regulations of secretions by salivary glands, liver, pancreas, stomach, small intestine and large intestine in the pig are discussed. The species and metabolism of gastrointestinal microflora along with their effects on the nutrient utilization and energy requirement of the pig are described. Quantitative measurements of nutrient digestion and absorption based on the sum of the end products from the actions of enzymes secreted by the pig and the gut microflora are also discussed. This chapter further provides a short review on feed intake control in pigs and it ends with some thoughts for using the pig in biomedical research of the digestive system. |
