Nutrition Key to Increasing Productivity in Intensive Breeding

The Beef Site - Improving the productivity of Brazilian livestock means not only finding ways to make the cattle produce more meat or more milk, but also addressing issues such as diseases.

Another focus of the group is the study of cattle adaptation methods. For example, the researchers attempted to ascertain the ideal transition time with regard to grazing animal nutrition in containment areas.

"Fourteen days is the minimum window we have observed for removing the animal from pasture and ensuring that it eats close to 80 per cent or 85 per cent concentrate. It is the interval for transitioning the animal - changing its diet gradually in an effort to prevent digestive problems like acidosis," Dr Millen said.

During FAPESP Week Nebraska-Texas, a symposium that gathered researchers from the United States and Brazil from September 18 to September 22 in the cities of Lincoln (Nebraska) and Lubbock (Texas), Millen showed to the audience at the University of Nebraska-Lincoln the results from his studies with nutritionists and from his research on ruminants feed, based on a model developed by Professor Michael Galyean, currently Provost of Texas Tech University - which took part in FAPESP Week. The goal of Millen's lecture was to provide a clearer understanding of the developments in nutritional recommendations and management practices in the production of feedlot cattle in Brazil.
