Organ Weights and Intestinal Morphology of Broiler Chickens Fed Diets Containing Different Supplements

The present study was evaluated the effect of dietary inclusion of various feed supplements and their combination on the performance index, glucose and serum cholesterol for 6 weeks. Day-old broiler chicks (n=252) were randomly assigned to seven treatment groups, each with 3 replicates. The first treatment was designated as control (T0) in which no supplement was added to the feed, while in treatments T₁; organic mineral mixture (Organomin forte), T₂; organic mineral mixture (Vannamin), T₃; probiotics (Microguard), T₄; enzyme (Brozyme -XPR) and probiotics, T₅; emulsifier (Lipigon) were provided through feed. In the T₆ group, 3 percent less energy was given through feed. The weight of vital organs viz. heart, liver, gizzard, and spleen were significantly (P<0.05) increased by the feed supplements of which were in the normal range. The gut morphology was also favorably altered due to feed supplementations. This indicates that the organic mineral mixtures, probiotics, enzymes and emulsifiers, and their combinations can be used as a growth promoter in broiler diets and can improve gut health. These products show promising effects as alternatives for antibiotics as pressure to eliminate growth-promoting antibiotic use increases.
