This study was conducted to evaluate management strategies in Mombaça grass pastures (Panicum maximum) under intermittent grazing subjected to different residual heights. A randomized-block design with two treatments (two post-grazing residual heights: 30 and 50 cm) and three replications was adopted. Pasture heights pre- and post-grazing, forage mass and accumulation, rest and occupation periods, pasture morphological components, milk yield and quality forage were evaluated. The data were submitted to analysis of variance and the means were compared by the F test at 5% probability. A longer grazing interval was observed in the treatments under the more severe grazing intensity. For forage mass post-grazing, larger production and higher percentage of...

Repeatability and phenotypic stabilization of Panicum maximum accessions
Provedor de dados: 2
Autores: Martuscello, Janaina Azevedo; Braz, Thiago Gomes dos Santos; Jank, Liana; Cunha, Daniel de Noronha F. V. da; Lima, Bruno Patrick da Silva; Oliveira, Leandro Pereira de.
The experiment aimed at determining repeatability coefficients for four methods (analysis of variance, principal components-correlation and covariance matrices and structural analysis), number of harvests necessary to increase accuracy and phenotypic stability of yield characteristics of accessions of Panicum maximum. The experiment was conducted in a completely randomized design with 35 genotypes and three replications. Five cuts were made and material was weighed and dried to obtain total, stem, leaf and dead forage dry matter yields. The repeatability coefficients in the different methods, for the evaluated characteristics, ranged from 0.1867 and 0.6583. The estimates of repeatability coefficients obtained for the evaluated characteristics by analysis...

Macauba palm cake as additive in elephant grass silage
Provedor de dados: 2
Autores: Silveira, Hugo Vinícius Lelis; Braz, Thiago Gomes dos Santos; Rigueira, João Paulo Sampaio; Santos, Márcia Vitória; Gusmão, Jéssica Oliveira; Alves, Matheus Almeida; Martuscello, Janaina Azevedo; Mourthé, Mário Henrique França.
The aim of this study was to evaluate the addition of macauba palm cake (Acrocomia aculeata) on the chemical composition, fermentation and aerobic stability of elephant grass silages (Pennisetum purpureum). The experiment was performed in a completely randomized design with four replicates. The treatments were composed of six levels of macauba palm cake (0, 6, 12, 18, 24, 30%) as additive to elephant grass silage. Dry matter and ethereal extract content of the silage increased linearly with the inclusion of the additive. Addition levels of 15.54% would provide 35% of dry mass, and the limit of 7.00% of ethereal extract in the silage could be obtained with 10.47%. The neutral detergent fiber content reduced linearly from 68.97 to 52.59%, but lignin...
