Microbiology of the gastrointestinal tract of turkey fed fermented and non fermented liquid feed
Abstract
The microbiology of the gastrointestinal tract of turkey fed fermented and non- fermented liquid feed was investigated in an experiment that lasted for 12 weeks. Sixty five day old poults were used for the experiment. In a Completely Randomized Design each treatment was replicated 3 times with 7 birds per replicate. Commercial poultry starter and growers diets were used such that T1 is dry feed, T2 diet was non fermented liquid diet while T3 diet was fermented with lactobaccilus acidilactici. Non fermented feed (T2) was prepared daily by mixing the dry feed with water in a feed to water ratio of 1:2 while the fermented liquid feed (T3) was prepared by the addition of lactobacillu acidlactici, a strain of lactic acid bacteria for a period of 24hrs at temperature of 3oC . The birds were given ad liitum access to experimental diets and water. Data was collected on the pH value of feed, Lactic Acid Bacteria: coliform ratio, coefficient of correlation. indicates; significant (p < 0.05) higher concentration of lactobacillus spp in T3 (0.00021 CFU), significant (p<0.05) higher lactobacillus- coliform ratio in T3 (7.04 CFU), higher concentration of salmonella spp in T1 (0.000042) and higher concentration of sacharomyces spp in T2 (0.00060 cells/ml). Cost benefit analysis indicated higher cost of production in T2 and T3 with mean values of ₦1743.42 and ₦1770.26 respectively. Similarly, higher revenue was generated in T2 and T3 turkeys with mean values of ₦696.58 and ₦1014.74 respectively. Results for coefficient of correlation of GIT bacteria to body weight of turkey shows that lactobacillus and lactobascillus- coliform ratio were positively correlated while coliform, salmonella and saccharomyces spp were negatively correlated to body weight of turkey. This study therefore concluded that turkeys fed T3 diets fermented with lactic acid bacteria culture had a better microbial profile, highest Body weight, better cost benefit ratio and better result for correlation.
