Effect of spineless-cactus mucilage on the in vitro rumen fermentation of cellu...
Pinho,Ricardo Martins Araujo; Santos,Edson Mauro; Oliveira,Juliana Silva de; Loureiro,Alexandre Henrique Remigio; Macêdo,Alberto Jefferson da SilvaSUMMARY The aim of this study was to evaluate the effect of the levels of spineless-cactus mucilage on the in vitro rumen fermentation of cellulose, starch, and protein. A completely randomized experimental design was adopted with a 5 × 3 factorial arrangement consisting of five levels of spineless-cactus mucilage (0, 5, 10, 20, and 40%) and three substrates (carboxymethylcellulose, starch, and trypticase). Tre...
Sorghum cultivars of different purposes silage
Pinho,Ricardo Martins Araujo; Santos,Edson Mauro; Oliveira,Juliana Silva de; Bezerra,Higor Fábio Carvalho; Freitas,Poliane Meire Dias deThis study aimed to assess the fermentation profile, losses and chemical composition of the silages of five sorghum cultivars. A completely randomized design with five replicates was used. The experimental treatments were represented by five sorghum cultivars (Sorghum bicolor (L). Moench): 'BRS Ponta Negra' , 'BRS 610', 'BRS 655', 'BRS 800' and 'BRS 810'. There was variation (P<0.05) for the pH in the cultivars...
Silages of pearl millet submitted to nitrogen fertilization
Pinho,Ricardo Martins Araujo; Santos,Edson Mauro; Campos,Fleming Sena; Ramos,João Paulo de Farias; Macedo,Carlos Henrique OliveiraThis study aimed to evaluate the fermentation characteristics, losses and the chemical composition of two pearl millet genotypes silages submitted to nitrogen fertilization. The experimental design was a completely randomized blocks in a split plot scheme 2x5 (two nitrogen genotypes doses x five doses of nitrogen), with four replicates. Nitrogen doses were 0, 20, 40, 60, 80kg ha-1 and the pearl millet genotypes...
Fenos de capim-buffel amonizados com ureia
Bezerra,Higor Fábio Carvalho; Santos,Edson Mauro; Oliveira,Juliana Silva de; Pinho,Ricardo Martins Araujo; Perazzo,Alexandre FernandesObjetivou-se quantificar a população de mofos e leveduras, avaliar as perdas de matéria seca e a composição bromatológica de fenos de capim-buffel amonizados com ureia. Utilizou-se um delineamento inteiramente casualizado, com cinco tratamentos e cinco repetições. Os tratamentos compreenderam aos níveis de ureia (0; 0,5; 1,0; 2,0; 4,0%), que foram adicionados aos fardos de feno com base na matéria seca. A inclu...
Carcass characteristics of lambs fed diets containing silage of different genot...
Suassuna,Juraci Marcos Alves; Santos,Edson Mauro; Oliveira,Juliana Silva de; Azevedo,Paulo Sérgio de; Sousa,Wandrick Hauss deThirty-five feedlot lambs (without defined breed, aged between 5 and 7 months, with average live weight of 17.7±3.7 kg) were used in a completely randomized design to evaluate the effect of diets containing different genotypes of sorghum on morphometric measurements and qualitative characteristics of carcass and yields of primal cuts. The animals stayed in individual indoor pens for 42 days and slaughtered at a...
Agronomic evaluation of 32 sorghum cultivars in the Brazilian semi-arid region
Perazzo,Alexandre Fernandes; Carvalho,Gleidson Giordano Pinto de; Santos,Edson Mauro; Pinho,Ricardo Martins Araujo; Campos,Fleming SenaThe objective of this study was to evaluate agronomic characteristics of 32 sorghum cultivars (Sorghum bicolor(L). Moench) in the Brazilian semi-arid region. The experimental design was set up in randomized blocks with three replications. Treatments were the 32 sorghum cultivars. The evaluated variables were: plant height, stem diameter, tiller density, number of green leaves per tiller, average leaf length, dr...
Effect of whey fermented by Enterococcus faeciumin consortium with Veilonella p...
Bezerra,Higor Fábio Carvalho; Oliveira,Juliana Silva de; Santos,Edson Mauro; Queiroz,Augusto César de; Mantovani,Hilário CuquettoThe objective of this research was to evaluate the effect of whey fermented by Enterococus faecium in consortium with Veilonella parvula in vitro on ruminal microorganisms in different substrates, with or without monensin. The first experiment was carried out in a completely randomized design, in a 6 × 3 factorial arrangement (six substrates × three whey levels) with two replicates. In experiment two, a 2 × 3 ×...
Avaliação de genótipos de milheto para silagem no semiárido
Pinho,Ricardo Martins Araujo; Santos,Edson Mauro; Rodrigues,José Avelino Santos; Macedo,Carlos Henrique Oliveira; Campos,Fleming SenaObjetivou-se com esta pesquisa avaliar o rendimento forrageiro, as características agronômicas e morfométricas das plantas e as perdas, perfil fermentativo e composição bromatológica de silagens de genótipos de milheto. Para avaliação das características agronômicas e morfométricas dos genótipos utilizou-se o delineamento experimental em blocos casualizados, com cinco repetições. Na fase de avaliação dos silos ...

Microbial and fermentation profiles, losses and chemical composition of silages...
Pinho,Ricardo Martins Araujo; Santos,Edson Mauro; Carvalho,Gleidson Giordano Pinto de; Silva,Ana Paula Gomes da; Silva,Thiago Carvalho daThe present study evaluated the microbial population, fermentation profile, losses and dry matter recovery, and chemical composition of silages of buffel grass at different cutting heights. To evaluate the microbial fermentation dynamics, the treatments resulted from a 4 × 5 factorial combination consisting of 4 cutting heights and 5 fermentation periods, in a completely randomized design with three replication...
