Evaluation of microbial omega-3 long chain polyunsaturated fatty acid supplement in animal feeds

Changes in consumers’ lifestyles and food preference as well as increasing population growth increase demand of meat consumption. Environmental considerations, globalization influences, competition and political intervention have also impacted livestock and aquaculture industries. Increased consumption of omega-3 fatty acid has been associated with beneficial effects for the prevention of different pathologies, mainly the cardiovascular diseases, and inflammatory processes. Approaches to support the substantial growth in domestic-animal production by enrichment of omega-3 fatty acid in animal meat products using microbial omega-3 supplement diet feeding have been applied.

Our previous study has supported by Cluster and Program Management Office (CPMO), NSTDA indicated benefits of omega-3 long chain polyunsaturated fatty acids producing Aurantiochytrium limacinum BCC52274 as feed supplement on growth performance of post-larvae shrimp and enhanced product quality with a high level of docosahexaenoic acid (DHA) deposition in muscle tissue of juvenile shrimp in laboratory scale as well as the preliminary test in chicken. The purpose of this project with a Biowealth co., Ltd. collaboration is to obtain further field trial data to demonstrate efficiency of microbe supplemented feed on growth performance and product quality of shrimp, chicken and cow. The results will lead to application and development of supplement products in the feed industry as well as promoting the bio-based technology for the sustainable domestic farming in Thailand.
