Performance of beef cattle fed diets containing Stylosanthes and corn silages

摘要

Reports of the use of tropical legumes in silage production are scarce as these legumes have high contents of crude protein, low water soluble carbohydrate and high buffering capacity, which inhibit the production of silages with good fermentation andnutritional characteristics. Recent research has, however, shown that it is possible to produce good quality silages using tropical legumes (Pereira et al. 2012). Souza et al. (2012) concluded that silage produced from Stylosanthes cv. Campo Grande {Stylosanthes capitata + Stylosanthes macrocephald) at 60% proportion of the dry matter of the diet can replace corn silage in diets for beef cattle in feedlots without altering their intake and productive performance. However, the ideal proportion of this silage in the diets for beef cattle is still unknown. Thus, the objective of this study was to evaluate the intake and performance of beef cattle fed diets with Stylosanthes and corn silages.
