Abstract

Little is known about the macromineral requirements of goats and there are no publications which compare the requirements among different sexes. In this sense, the objective of internship abroad is to estimate Ca, P, Mg, Na and K requirements for maintenance and gain of intact male, castrated male and female Saanen goat kids. The growth requirements will be estimated using data from Fapesp project (2014/07327-8) and different models will be evaluated. The linear allometric equations will be used to predict macromineral concentration of the empty body weight (EBW) (kg) through of the logarithms of allometric equations recommended by ARC (1980). To innovate in the data analysis, the macromineral concentration of the EBW will be estimated using non-linear equations. A linear regression of the retained minerals (Ca, P, Mg, K and Na; g of mineral/kg of EBW) in the body tissue on mineral intake (g of mineral/kg of EBW) will be used to calculate the net mineral requirements for maintenance. In addition, the graduate student will follow the activities developed by foreign team, which will contribute for learning of different methodologies from those found in Brazil, contributing for human resources formation of quality. At the end of the internship abroad, the graduate student will have written and submitted a scientific paper, contributing to visibility and impact of the Brazilian science. The internship abroad will be developed at Texas A&M University located in the United States of America, under the supervision of professor Dr. Luis O. Tedeschi, from March to September 2015. (AU)
