BIOCHEMICAL PARAMETERS CHANGE INDUCED BY ADDING A MIXTURE PROBIOTIC FOOD MEAT CHICKENS

Abstract

Probiotics are live microorganisms that, when administered through the digestive tract, have a positive impact on the host's health. Microorganisms used in animal feed are mainly bacterial strains belonging to different genera, e.g. Lactobacillus, Enterococcus, Pediococcus and Bacillus. This experiment was conducted to biochemical study the effects a mixture of five Lactobacillus cultures (which belong to two species) included in broiler chickens diet. The study was realized on two groups of broiler chickens one-day (Ross 308) as follow: group M (50 chickens) – received only standard food – and group E (50 chickens) – received standard food with an addition of 0,1% mixture probiotic (1x10 viable cells per gram). The basal diet was a corn-soybean diet formulated to meet nutrient requirements. The experiment was carried out for 42 days. At age of 14, 28 and 42 days blood samples was taken to determine glucose, total proteins, albumin, triglycerides and cholesterol. Biochemical profile indicates a reduction in the level of cholesterol and triglycerides as a result of probiotic addition, the action of Lactobacillus on lipid metabolism in birds and effect on intestinal absorption of the end products of metabolism.
