Provedor de dados: 96
Autores: Caetano,Graciele Araújo de Oliveira; Villela,Severino Delmar Junqueira; Oliveira,Margarida Maria Nascimento Figueiredo de; Leonel,Fernando de Paula; Tamy,Wagner Pessanha.
The objective of this study was to determine the kinetics of in situ degradability parameters of the dry matter (DM) and neutral detergent fiber (NDF) and the passage of materials originating from the ensilage of the waste from pineapple cultivation (aerial parts). The four treatments utilized were silage of pineapple waste compacted at 600, 700, 900 and 1000 kg/m³. After ensiling the material from the pineapple cultivation, the particle-transit and rumen-degradation kinetics were analyzed. For the analysis of particle transit, chromium was utilized as a marker to mark the fiber. Passage rates were determined by retrieving the markers in the feces of the animals. In the degradation assay, samples were incubated in nylon bags for 0, 6, 18, 48 and 96 hours....

Kinetics of transit and degradation of the fiber from guinea grass silages enriched with waste from soybean pre-cleaning
Provedor de dados: 96
Autores: Fialho,Filipe Ton; Villela,Severino Delmar Junqueira; Leonel,Fernando de Paula; Tamy,Wagner Pessanha; Araujo,Raphael Pavesi; Machado,Henrique Valentim Nunes.
The objective was to study the kinetics of transit and degradation of the fiber from guinea grass and the waste from soybean pre-cleaning (WSPC), ensiled with different proportions of mass (0, 100, 150, and 200 g WSPC/kg total mass). Four crossbred (Gyr × Holstein), fistulated cattle with an average body mass of 400±50 kg were organized in a 4 × 4 Latin square experimental design. The fiber utilized in the study of the transit kinetics was stained with chromium mordant, whereas the in situ technique was adopted for the degradation kinetics. The level of inclusion of WSPC only affected the true digestibility and the mean retention time. The addition of waste from soybean pre-cleaning to the silage of guinea grass is beneficial, in terms of kinetics of...

Rumen degradation and passage kinetics of silage made from different corn hybrids
Provedor de dados: 96
Autores: Araújo,Karoline Guedes; Villela,Severino Delmar Junqueira; Leonel,Fernando de Paula; Tamy,Wagner Pessanha; Gomes,Raphael dos Santos; Abreu,Matheus Lima Corrêa.
The objective of the present study was to evaluate the parameters related to the digestion of the fiber from silages of four corn hybrids (BX1280, SHS4070, 2B433, and DKB390) developed for silage production. Four rumen-cannulated castrated Holstein × Zebu crossbred cattle with approximate initial weight of 400 kg were distributed in a Latin square design. To determine the fiber passage rate and degradability, the techniques of chromium-mordant and in situ incubation of the neutral detergent fiber of the silages in nylon bags were used. The profiles of concentration of the marker in the feces were described by the generalized two-compartment model. Corn hybrid DKB390 is the most indicated for production of better-quality silages, because its fiber is more...

Yield and quality of silage of maize hybrids
Provedor de dados: 96
Autores: Araújo,Karoline Guedes; Villela,Severino Delmar Junqueira; Leonel,Fernando de Paula; Costa,Patrícia Monteiro; Fernandes,Leonardo de Oliveira; Tamy,Wagner Pessanha; Andrade,Vinícius Raimundi.
The objective of this research was to identify the potential of maize hybrids for the production of silage. Hybrids 1671B, 2B433, 20A78, SHS4070, BX1280 and DKB390 were tested in a randomized block design with three replications. The hybrids yields were evaluated (average plant height, height of ear insertion, number of broken and lodged plants/ha, leaf:stem and ear:plant ratio and production of of DM, CP and TDN/ha). There was no difference between hybrids for the variables studied, except for the height of ear insertion. With respect to chemical characteristics, N-NH3/NT organic acids, and pH, there was also no difference between cultivars and hybrid silages are rated as of very good quality.
