The Animal Science Department from Faculty of Agrarian and Veterinary Sciences, UNESP (Jaboticabal/Sao Paulo/Brazil) offers a Postdoctoral opportunity (for Brazilians and foreigners) with a grant.
Requirements of candidate
Candidates should have Ph.D. degree for no more than 7 years in Animal Science or Veterinary Medicine, may not have employment relationship, should dedicate exclusively to the research project, have proven experience on research related to protein and amino acid requirements for poultry and have advanced knowledge on writing, reading and speaking English, or have studied abroad in an English speaking country.

Documents should be attached in an email to the coordinator of the project, Dr. Nilva Kazue Sakomura (). Any questions about this opportunity, please contact Nilva Kazue Sakomura ().
The selected candidate will work in the development of thematic project "Modeling production and nutritional requirements of poultry and fish" (Fapesp Process 2013/25761-4). The activities to be performed are: - Develop the research project “Mechanistic modeling to predict amino acid intake for broiler chickens”, related to the thematic project, according to abstract below; - Participate in the development of new methodologies that will be standardized during the course of the project; - Develop activities related to the thematic project, supporting students on the development of thesis and dissertations, contributing to the development and appropriate conduction of studies, as well as writing reports and scientific papers.
Abstract of the research project to be conducted
Currently, the software Avinesp considers the growing of two compartments, body and feathers in order to calculate the ingestion of amino acids. Both compartments are considered separately, although it is assumed only one value for the efficiency of utilization to calculate the amino acid deposition on body and feathers. Nevertheless, to elaborate mechanistic models proposed in this thematic, the efficiency of utilization from body and feathers must be considered separately. In this context, the goal of this project is to elaborate mechanistic models, according to the partial efficiency of utilization from body and feathers, to predict amino acid intake of broiler chickens. The studies that are being developed in this thematic project (n0 2013/25761-4) will allow the elaboration of a model to predict the amino acid intake classified mathematically as deterministic, dynamic, and mechanistic. The initial model will be deterministic, explaining the response of an individual. Moreover, the model will be turned to dynamic, using the chickens growing curves and the amino acids deposition in body and feathers for each chickens strains evaluated on the thematic project (n0 2013/25761-4). The mechanistic model to be developed, will integrate the equations of body growth, feathers and the respectively efficiency of utilization of amino acids. Furthermore, the models will be rewritten in Excel language as a way to turn the knowledge accessible, didactic and to disclose the use of mechanistic modeling, consolidating the scientific understanding between nutrition and protein metabolism. The spreadsheet will be a didactic tool with a simple understanding, aiming academic and poultry producers, encouraging its use. In this sense, one more product will be available for academic and poultry producers’ community as a result of a thematic project (process Fapesp n0 2013/25761-4).
