Sažetak
In modern poultry production animals are subject to various forms of stress from the moment they hatch to the finishing phase of the production cycle. Ongoing stress is a cause of many negative aspects in poultry production like reduced performance, and increased incidence of infectious and noninfectious diseases. Considering recent EU policy of excluding antibiotics and other medicinal products from animal feed, because of the well known dangers of resistant microorganisms, nutritional solutions will gradually become the most likely alternative in intensive production systems. Nutritive solutions include the use of biologically active components of feed which are called nutricines or functional food. Most important nutricines include different molecules like antioxidants, enzymes, emulsifiers, carotenoids, organic acids and non-digestible oligosaccharides. The function of nutricines in the animal organism can be described in several different ways. Organic acids and antioxidants maintain feed quality, while enzymes help with the digestion and the level of nutrient utilization. Carotenoids have a stimulative effect on the immune system which reduces the incidence of disease. Non-digestible carbohydrates and organic acids modulate the micropopulation of the digestive tract by supporting the proliferation of beneficial microorganisms and reducing the incidence of digestive disorders. By controlling oxidative stress, antioxidants have a direct effect on the health of the animals in the intensive production, and have a certain effect on meat quality. This review article will focus on recent findings in interaction of nutricines and stress, and their influence on health and performance in intensive poultry production systems.
