The objective of this study was to evaluate the flow of nitrogenous compounds, protein degradability, rumen degradation of total carbohydrate and organic matter and microbial efficiency in heifers subjected to diets containing corn silage, sugarcane or Tifton. For this purpose, the 2,6-diaminopimelic acid (DAPA) technique was adopted and analytical procedures for amino acids by HPLC were adapted. Six rumen-fistulated Holstein-Zebu heifers with 480 kg of initial BW and at 24 months of age kept in individual tie stalls were assigned […]

The effects of enzyme complex SSF (solid state fermentation) on growth performance and the availability of sucrose and monosaccharides in the chyme of Nile were involved. The study included 360 fish (70g±4.43) in a completely randomized design with six dietary treatments (0, 50, 100, 150, 200 and 250 ppm of SSF) arranged in six replicates, with 10 fish per replicate. Every 15 days, one tilapia of each experimental unit was sacrificed for analyses of carbohydrate in the chyme. On day […]

Factors that limit the digestion of tropical forages are associated to the dynamic of cell wall phenolic acids. The study of these compounds in forages may be facilitated by the availability of sensible methods that permit processing large amounts of samples. The present paper describes a method for determining phenolic acids in forage cell wall through high-performance liquid chromatography (HPLC). Sugar cane bagasse, elephant grass and cassava leaves were used as experimental samples. To remove soluble low molecular weight products, […]
