Southland Organics has released the results of a case study involving the product Big ole Bird (Biology Optimized for Birds) as favorable. The goal of the case study was to investigate Big ole Bird’s effectiveness in reducing or eliminating the effects of Enteritis caused by Clostridium.

The case study was conducted by Southern Poultry Research. To perform the research, the team chose to use Cobb-Vantress broiler chickens (Cobb 500). These chickens were gathered from Cobb-Vantress in Cleveland, Ga. The chickens were treated with routine vaccinations and only completely healthy chickens were used to complete the study. Upon retrieval, the chickens were separated into three categories: the Control Group, the Infected Group and the Study Group.

The Control Group received no water additive and were not challenged with Clostridium. The Infected Control Group received no water additive and were challenged with Clostridium broth. The Study Group were challenged with Clostridium and received Big ole Bird probiotic water treatment. The chicks challenged with Clostridium were given the Clostridium broth for three days (Days 19, 20, & 21), which included the Infected Control Group and the Study Group.


At the conclusion of the study, the results were favorable towards those treated with Big ole Bird. The chickens infected with Clostridium and treated with Big Ole Bird showed a 0.8% decline in feed intake, 7.1% improvement in feed conversion and a 6.7% improvement in weight gain over the Infected Control Group. Mortality was also improved by 6.2% in the group treated with Big ole Bird.

The results of the study prove that Big ole Bird provides lower mortality, better feed conversion and more substantial weight gain across the flock.
