Abstract

In the Us and Brazil, consolidation of large numbers of animals into small land areas to improve the efficiency of meat and milk production may contribute to environmental problems unless animals are fed and managed properly. Any animal operation that does not have proper nutrition, feeding, management and waste-disposal program has the potential to pollute the environment. Several research projects that are being carried out at UNESP deal with understanding of nutritional requirement of livestock, particularly goats and poultry. The researchers at UC Davis have been involved in mathematical modeling of biological systems for few decades. The expertise they bring is in carrying out statistical and mechanistic modeling using state-of-the-art tools. Therefore, there is a natural fit between researchers at UNESP and UC Davis to work together in coming up new and update nutrient requirement models for goats and poultry. The exchange activities will focus on using the considerable amount of data is collected by UNESP researchers for modeling purposes by post-doctoral fellows in conjunction with researchers at both institutes. The nutrient models are expected to have an impact on the livestock industry and help producers achieve not only economic benefit but also environmental benefit by allowing them to provide their livestock accurate amount of nutrients to meet their requirements. The projects entitled “Development of Models for Predicting the Nutritional Requirements for Growing Goats” (2014/14734-9) and “Modeling production and nutritional requirements of poultry and fish” (2013/25761-4) are directly related to the exchange activities. The statistical approaches that will be worked during the exchange activities will be relevant in improving the quality of the results, and ultimately will make possible to apply state-of-the-art statistical analysis in the data. The main products of the exchange activities will be 2 collaborative scientific papers for publication in a reputable journal. Furthermore, the approaches applied in the project will play an important role in the establishment of the collaboration and in the impact of the future publications. In addition, the PIs will organize a workshop of “Understanding of Nutritional Requirement to Reduce Environmental Impact of Livestock” in December 2017, which will be held in Brazil and will be important in disseminating the results of the collaborative work.
