COMBATING POULTRY STRESS:Is Spray-Dried Plasma the best protein alternative?

摘要

Aseries of stress factors such as disease (necrotic enteritis, coccidiosis and others) or environmental and production conditions or factors (litter quality, heat stress, stocking density, etc.) can have negative impacts on poultry production. Depending on the nature and extent of the stress, various consequences such as increased mortality, higher feed/weight gain ratios, bodyweight reduction or reduced pigmentation can occur, which all influence the profitability of the system. Stress factors can have subclinical effects in the body, including, the overreaction of the immune system that can cause impairment of the intestinal barrier function and reduce utilisation of nutrients for productive functions.
