Última Estimate of the optimal level of concentrates for dairy cows on tropical pastures by using the concept of marginal analysis R. Bras. Zootec. Oliveira,André Soares de; Campos,José Maurício de Souza; Lana,Rogério de Paula; Detmann,Edenio; Valadares Filho,Sebastião de Campos. It was adopted in this work a methodology to estimate the optimal level of concentrate food for dairy cows on tropical pastures based on the theory of marginal analysis. An empiric model was developed and validated for application of the methodology using a database composed of 62 means of treatments from 32 studies in which milk production was evaluated regarded to the levels of concentrate feeding. Milk production (MP) showed quadratic behavior in response to concentrate intake (CI): MP (kg/cow/day) = 10.554 + 1.5855CI - 0.0552CI². Evaluation of the MP values observed over the predicted ones pointed the non-rejection of the null hypothesis, indicating that the model can be applied on the prediction of milk production, and consequently, on the optimal...
