Efficacy of Bactocell® and Toyocerin® as Probiotics on Growth Performance, Blood Parameters and Intestinal Morphometry of Turkey Poults

A feeding trial was conducted to investigate the efficacy of Pediococcus acidlactici (Bactocell®) or Baccillus cereus (Toyocerin®)-based probiotics on turkey’s performance, carcass yield, blood parameters and intestinal morphology. A total of 240 1- day-old male Nicholas turkey poults were allocated into three dietary groups with four replicates. A corn-soybean-based diet was used as a basal diet. The dietary groups were 1) control (basal diet), 2) basal diet plus Bactocell® (1×109 cfuof Pediococcus acidilactici/g of the diet) 3) basal diet plus Toyocerin® (1×109 cfuof Bacillus cereus/g of the diet). Poults assigned in a normal condition from 1 to 84 days of age. Birds raised on floored pen and in an environmentally controlled house. Birds given ad libitum access to water and diet. Poults weighted at every week by pen basis to determine average body weight. Feed intake per pen recorded at the same age and feed conversion ratio calculated for whole period. Eight birds per treatment randomly selected to measure the serum cholesterol, triglyceride, heterophil, lymphocyte levels and histomorphological measurements of small intestine on day 84. The result of this study shown that there was not a significant association between added probiotics to feed and weight growth, feed conversion ratio, cholesterol, triglyceride,high-density lipoprotein (HDL) andlow-density lipoprotein (LDL) levels (P>0.05). There was a significant result of decrease epithelium thickness, increase villus height and increase cell area of Goblet (P
