The research aimed to evaluate the influence of irrigation and sequential grazing day on chemical composition and "in vitro" digestibility of Napiergrass and Mombaça-guinea grass. The irrigation supplied the previous ten-year mean daily evapotranpiration (ET0). It was adopted the rotational grazing, with grazing period of four days, resting period of 32 days and variable stocking, with grazing ...

Phosphorus and phytase levels for layer hens

REZENDE, J. C. R. et al. [2013-]

The objective of this research was to evaluate the performance and bone quality of laying hens after peak production fed diets containing phosphorus levels and phytase. An experiment was conducted with 384 Hy-line distributed in a completely randomized in a factorial 4 x 3 with 4 levels of available phosphorus and 3 levels of phytase. The experimental period was divided into four periods of 28 ...

28 and 42 days) in three cultivars of Cynodon (Tifton 85, Jiggs and Vaquero) for two seasons (summer and winter), through growth analysis. The experimental design was completely randomized with four replications. Harvesting every 42 days resulted in higher Culture Growth Rate - CGR (30.9 g DM/m2/day) in the summer. In winter the CGR was higher under the 14 (11.6 g DM/m2/day) and the 28 days af ...
