Simulating the effect of climate on star grass growth and quality and its capacity to support milk production in the tropical regions of Mexico Ciência Rural
Angel,Gilberto Yong; Silveira,Vicente Celestino Pires; Nova,Francisca Avilés; Ortega,Octavio Alonso Castelán.
The objective of the present study was to simulate the effect of the seasonal variation of climate on the nutritional value and dry matter yield of star grass and its capacity to support milk production alone or with concentrate supplementation in small-scale milk production systems in the tropical regions of Mexico. Two mathematical simulation models were used, the first model simulates the growth and yield of star grass (Cynodon plectostachyus), and the second model simulates the productive performance of dairy cows. Both models were integrated in a decision-making support system (DSSTROP). Model's predictions were validated by a calibration exercise for each data set from three experiments on the effect of concentrate supplementation on milk yield. The...
