Efficiency of the introduction of different Ca levels in broiler chicken diets as part of dietary fiber extrudates

Abstract

Abstract One of the main tasks of industrial poultry farming is the introduction of new technologies that reduce the cost of obtaining products through the use of non-traditional feed components. The aim of the research is to study the effectiveness of the technology of extrusion processing of feed components at the stage of interaction with the biome of the poultry digestive system. It was found that the inclusion of extruded bran in the diet is accompanied by a significant increase in the number of Lactobacillus. Moreover, the most significant growth was observed in the intestines of a bird receiving an extrudate with an input of 20 % calcium. This group was also characterized by a maximum growth of Escherichia 7.3 times in comparison with the control. The introduction of an extrudate with a content of 10 % calcium is associated with a decrease in the number of E. coli in the cecum of chickens. Thus, pretreatment of non-starch polysaccharides together with calcium in the extruder stimulates abdominal digestion of chickens, which indicates the possibility of their use in industrial production.
