Performance, efficiency and estimated maintenance energy requirements of Bos taurus and Bos indicus cattle

  • Chapter

Abstract

The NRC (2000) concluded that maintenance requirements of Bos indicus cattle were about 10% lower than those of Bos taurus cattle, however other reports do not support any difference between breed types (Tedeschi et al., 2002). A recent focus on genetic selection for increased feed efficiency has led to greater efforts to quantify individual feed intakes on farms and research institutes. This study has combined several of those data sets, including B. indicus and B. taurus cattle, in high and low efficiency categories, in order to revisit the maintenance issue.
