This experiment aimed to evaluate the effects of environmental temperature and feed restriction on performance and characteristics of fiber types in the flexor hallucis longus muscle of male broilers. Three hundred twenty four five-day-old male chicks were allotted to a split plot design, where the main treatments were three feeding programs (ad libitum, early restriction – 8-14 days; later restriction – 29-35 days) and three environmental temperatures of growth (heat, termoneutral and cold) in a completely randomized factorial 3 x […]

This trial aimed to study the nutritive value of three Elephant grass clones (Cameroon, Roxo de Botucatu and Mott) and an Elephant grass with pearl millet hybrid (HV-241) cultivated under two different humidity conditions (with and without water stress). A randomized block design with split plots and three replicates was used. In the main plot, the effect of the humidity regimes was studied and in the split plot, the different clones. The dry matter (DM); crude protein (CP) and of […]

This work was carried out to evaluate the cutting effect at 0, 15, 30 and 45 cm height, on the chemical composition of elephant grass (Pennisetum purpureum, Schum.) cv. Roxo in dry and rainy seasons. The samples were obtained from an useful area of 8,4 m2 from each parcel. After the uniformity cut two cuts in dry season with 90 days interval, and three cuts in rainy seasons with 60 days interval. A sample of 3 or 5 tillers was […]

ABSTRACT – The chemical composition and in situ dry matter (DM) and neutral detergent fiber (NDF) of bulky fraction (stall and sheets) degradation of 28 corn hybrids in 1996, and 21 hybrids, in 1997, were studied to establish the correlation among the analyzed factors. From the 21 hybrids selected in 1997, 13 were part of the experiment in 1996. The model for the evaluation of in situ DM degradation kinetics (McDonald, 1981), and the model to analyze the in situ […]
