Investigation of Broiler Chicken (Ross-308) Response Rates to Food Additives (Probiotics and Natural Acetic Acid)

Abstract

The main goal of this study was to see how well broiler chicks responded to food additives like probiotics and Natural acetic acid. a total of 150 broiler chicks were randomly assigned to three treatment classes, Ross-308 at one-day old. with 50 chicks for each replication. chicks in the first treatment received a control diet, chicks in the second treatment were fed on a diet supplemented with local probiotic-containing yeast Saccharomyces Cerevisiae added to the feed at a level of 4 Kg per ton feed while chicks in the third treatment received organic acetic acid at the level of 4 ml acid/100 L water in drinking water. the findings showed that chicks in T3 who obtained vinegar with drinking water had significantly higher body weight and feed intake at the marketing age (p ≤005) (8 weeks). No substantial differences have been observed in terms of feed conversion between T2 and T3 at 8 weeks old. In contrast with the control group, chicks receiving probiotic T2 or vinegar T3 had substantially (p ≤o.o5) less morality and a greater dressing percentage. the data also showed substantial dominance in organic acid and local probiotics. the findings also showed a significant presence of local probiotic and organic acid in reducing the percentage of mortality and the rise in the percentage of dressing relative to control treatment at the age of 8 weeks, although there were no major differences between them in the control group at feed efficiency at 4.8 weeks.
