Morphogenetic and structural traits of Ipyporã grass subjected to nitrogen fert...
Camargo,Francisco Carlos; Difante,Gelson dos Santos; Montagner,Denise Baptaglin; Euclides,Valéria Pacheco Batista; Taira,Carolina de Arruda QueirozABSTRACT: This study examined the effects of annual nitrogen (N) rates of 100 and 200 kg ha-1 on the morphogenetic and structural traits of Ipyporã grass (Brachiaria brizantha × Brachiaria ruziziensis) under intermittent grazing during the seasons of the year. The experiment was laid out in a randomized-block design with two treatments and three area replicates. Ipyporã grass pastures were grazed by beef cattle...
Effect of supplementation of ewes in the final third of gestation on the develo...
Campos,Nathália Rafaela Fidelis; Difante,Gelson dos Santos; Gurgel,Antonio Leandro Chaves; Costa,Carolina Marques; Montagner,Denise BaptaglinABSTRACT This study examined the effect of different supplementation strategies for ewes in the last third of gestation, kept on a deferred Brachiaria brizantha cv. Marandu pasture, on their performance and the growth curve of their lambs. A total of 54 ewes, of no defined breed, with an average weight of 41.10±3.10 kg, were used in a completely randomized design, divided into three groups (18 ewes per treatmen...
Principal component analysis of steers performance and structural and nutrition...
Gurgel,Antonio Leandro Chaves; Difante,Gelson dos Santos; Montagner,Denise Baptaglin; Euclides,Valeria Pacheco Batista; Araujo,Alexandre Romeiro deABSTRACT: There is little information about whether the increased secondary productivity observed in pastures fertilized with high nitrogen rates is attributable to fluctuations in the nutritional value or pasture structural characteristics, or both. This study aimed to identify a set of factors (structural and nutritional characteristics) that best explain the performance of beef steers grazing Mombasa grass p...
Mathematical models to adjust the parameters of in vitro cumulative gas product...
Gurgel,Antonio Leandro Chaves; Morais,Jucileia Aparecida da Silva; Santana,Juliana Caroline Santos; Difante,Gelson dos SantosABSTRACT: This study examined the use of the Gompertz, Groot, monomolecular, Richards and two-compartment-logistic mathematical models to investigate the kinetics of in vitro gas production of diets composed of combinations of Gliricidia hay or silage. In addition, the effects of Gliricidia hay or silage inclusion on the in vitro cumulative gas production of these diets were evaluated. Rumen fermentation kineti...
