| This study was conducted with the object of evaluate forage species that produce grains and chemical composition of their silages under the conditions of the Brazilian Northeast. They were evaluated four forages: maize, millet, sorghum and sunflower. It was determined the dry dead forage mass (DDFM), total dry mass of grain (TDMG), total dry mass of leaf (TDML) and total dry mass of stem (TDMS). Silage produced with the species was rated to the ammonia nitrogen, losses gases (G), losses effluent (E), dry matter yield (DMY), dry matter (DM), crude protein (CP), ether extract (EE), mineral matter (MM), neutral detergent fiber (NDF) and acid detergent fiber (ADF). Sorghum showed higher (p<0.05) accumulation of DDFM, TDMG and TDMS than maize, millet and... |

| Pornunça is a species of the genus Manihot that has been cultivated as an option for animal feeding in the Brazilian semi-arid. Leaf area (LA) is important to determine forage plant growth, whose evaluation model has to meet the following characteristics: practicality, precision and low cost. The objective of this study was to set a model to determine the leaf area in Pornunça (Manihot sp.) from morphometric measurements of the leaf. The experimental design was in randomized blocks with three methods for determination of leaf area, and three blocks, with 144 replicates (leaves). For the determination of LA, the direct method (FAReal), treadmill leaf area meter (Li-Color 3100©) and linear dimensions were used. Data were subjected to regression analysis.... |

| This study evaluated the replacement of Tifton hay with xiquexique (0, 12, 24 and 36%) on feeding behavior of lactating dairy cows. To this end, eight cows with average milk production of 15 kg milk day-1 and average body weight of 465.2 ± 39.4 kg were distributed in a double 4x4 Latin square. Each experimental period lasted 16 days, ten for adaptation and six for data collection. The record of behavioral variables was made every five min. for 24 hours. The times spent in feeding, ruminating and total chewing, expressed in hours day-1, as well as feeding (FE) and rumination (RE) efficiencies, expressed in g NDF h-1, the number of cuds and cud chews per day showed a linear decrease according to the levels of xiquexique in the diet. There was a linear... |
