The role of nutrition on the enteric health of broilers

摘要

Nutrients with effects on intestinal microflom include protein and amino acids, energy from either starch or fat, fibre, dietary mineral levels and electrolyte balance. The effect of specific raw materials, additives and processing techniques are highlighted and include cereals, optimal use of feed enzymes, fats, feed grist size, gizzard development, pelleting and extrusion. Maintaining good litter quality is critical for successful broiler rearing especially during the more challenging winter months. Opportunities exist for the nutritionist to influence litter conditions. Litter quality will be influenced by any enteric related disorders and may be related to the removal of antibiotic growth promoters and the removal of animal proteins and fishmeal from broiler diets in some countries. The degree and severity any disorders vary depending on the region, the poultry operation and the time of year.
