The objective of this study was to evaluate the genotypic stability of agronomic traits in hybrids of Panicum maximum. Hybrids originating from the crosses between two sexual parents and cultivars Mombasa and Tanzania were evaluated in an incomplete-block design. Evaluated traits were total dry matter, leaf dry matter, stem dry matter, percentage of leaves, and leaf:stem ratio. These traits were evaluated in six harvests. Overall, higher repeatability was observed for the traits total dry matter and leaf dry matter, especially […]

The objective of this trial was to develop simple regression equations for estimating the chemical body composition of Nellore steers by using the chemical composition of the 9-10-11th ribs cut. Twenty-seven feedlot Nellore steers varying from 338.0 to 503.6 kg of BW and from 21 to 31 months of age were used. Six reference animals were slaughtered at the beginning of the trial to estimate the initial chemical body composition. Contents of water, protein, EE, and ash of the 9-10-11th […]
