Technical Cooperation Project – Development of technique for utilization of microbes to improve productivity of the chicken

39By Gilberto Silber Schmidt

Labex Korea – Rural Development Administration (RDA) seems to meet required knowledge and constitutes a potential partner to integrate the Applied Biotechnology area for human and animal feed additives, health and welfare.

The bio prospection of Brazilian resources for new metabolites (enzymes) for food and feed application is relevant because Brazil is one of the main animal protein producer and investments in this area could work in favor of a less expensive production and/or more sustainable production systems associated to a healthier and tastier food.

The development of probiotics and prebiotics for human and animal health and welfare has the objective to evaluate of National microbes (bacteria, yeast and moulds) with potential as probiotics. Such kinds of additives have been used in favor of animal and human health improvement. Considering the enormous bioresources in Brazil, it is believed that many potential not yet discovered microbes could be identified and used for this proposal. Some Embrapa R&D Centers have been already working in this area, i.e., Embrapa Wine and Grapes, Embrapa Food Technology and others.

The use of biotechnology for prebiotic development has become more common along the last years. Additives like gums, flavors, toxin binders, gut health enhancers and others have been developed. As mentioned in the previously, it is believed that Brazil has an enormous potential in terms of biodiversity unexplored so far for this proposal.

Considering a growing demand of food and feed, it is expected that a higher output of contaminants to the environment will happen. Based on this statement a need for efficient biodegration systems enriched with potential inoculants coming from national resources seems to be another important development area. Microbes that turn de degradation of animal manure, urban effluents, slaughter houses effluents and other processes residues faster can be of extreme benefit in the near future. 

Alternatives to antibiotic growth promoters have been a concern. So far, there are no isolated natural alternatives capable to result in the same efficiency than the traditional antibiotics used in animal production. However, it has been assumed that a synergistic package of natural resources could be an alternative tool. Following this idea, one option for the future, could be the association of biotechnological products, especially combining herbal extract to fermentation products.

Based on this statement, development of a project that combines several natural resources seems very promising.

This Project of Technical Cooperation (TCP) beteween RDA and Embrapa is centered in sharing of information of interest to both countries. The objectives of it are: a) To develop the techniques for selection, identification and utilization of beneficial microbes suitable to the environment of Korea and Brazil for the improvement of chicken productivity and b) To Compare two different production processes: Solid State Fermentation and Submerged Fermentation.
