Effect of various concentration of butyric acid on growth performance, intestinal lesion scores, and body composition of broilers raised on used litter

There is still a need for the evaluation of alternative feed additives, including organic acids such as butyric acid, when fed in broiler diets without antibiotic growth promoters. The removal or limitation promoting antibiotics from commercial production changes opportunities additives poultry industry and allows replacement that may not have been cost effective are available. Therefore, an experiment was conducted to evaluate effects various concentrations (200 ppm, 400 800 ppm) coated acid on performance, intestinal lesion score, body composition 42-day-old broilers raised used litter. addition at ppm increased BW improved mortality corrected conversion ratio (FCRm) over 42-d period compared with negative control (NC) broilers. Although performance improved, lean mass fatty unchanged suggesting generalize response. No significant differences were observed scores duodenum jejunum overall low. Both able increase weight comparison NC birds, but required also improve FCRm birds.
