Influence of new lactulose-containing fodder additives on basic morpho-biochical indicators of blood and resistance of broiler chicken

Abstract

In modern industrial broiler poultry farming, the issue of combating the uncontrolled use of antibiotics in the process of growing poultry is being actively addressed. Currently, scientists are looking for an alternative solution to the issue of eliminating the use of antibiotics for prophylactic purposes. In this connection, researchers are intensively working on the development of innovative feed additives that can solve the problem with the immunostatus of the organism of poultry grown in conditions of great crowding. The article discloses the data of experimental experience on the use of new innovative lactulose-containing additives of domestic origin "Kumelakt-1" and "Laktuvet-1". Their positive effect on the morpho-biochemical parameters of the blood and the resistance of the poultry organism has been established. This information allows to predict in vivo the indicators of the safety of the poultry population and are indicators of the quality of the products obtained. New lactulose-containing innovative additives as a regulator of intestinal microflora improved the morpho-biochemical blood index and increased the resistance of the poultry organism. Namely: increased on average in I and II experimental groups in comparison with the control group, the hemoglobin index by 9.7%, erythrocytes by 10.8%, hematocrit by 5.6%. An increase in the level of urea in the blood serum was established by 10.4 and 9.7% (P <0.01), glucose - by 6.5 and 4.8 6.1 and 9.0% (P <0.05), phosphorus - by 8.2 and 6.6% (P <0.01), magnesium - by 9.9 and 9.1% (P <0.05), potassium - by 1.3 and 1.6% (P <0.05), iron - by 1.4 and 1.6% (P <0.05), respectively. The indicators of phagocytic activity in the experimental groups were determined, it was found that, on average, this indicator increased by 5.2% (P <0.05).
