The objective of this experiment was to evaluate the yield, nutrimental and in vitro ruminal fermentation profiles of maralfalfa grass (Cenchrus purpureus Schumach.) Morrone, at four harvest frequencies.
The objective of this research was to evaluate tiller population of orchard grass seeded with perennial ryegrass and white clover in different proportions and single. Treatments consisted of the associations: 20-70-10, 70-20-10, 100-00-00, 40-40-20 % of orchard grass (OG), perennial ryegrass (RG) and white clover (WT) respectively. Treatments were distributed in a randomized complete block with three replications. The association 70-20-10 of OG-RG-WT had greatest tiller density of OG with an average of 3,750 tiller m-2, and the lowest in 100-00-00 with an average of 2,400 tiller m-2 (P<0.05).
The objective was to evaluate the in vitro fermentation in silage of ripe mango with pangola grass hay and levels of sugar cane molasses as additive. The treatments were: 0 (T0%), 3 (T3%), 6 (T6%) and 9% (T9%) molasses. The ensilage was fermented for 21 days. Dry matter (DM), pH values, lactic acid, crude protein (CP), neutral detergent fiber
(NDF), acid detergent fiber (ADF), and ashes (As), partial and the accumulated biogas and methane production, DM degradation (DMD) and NDF degra dation (NDFD) were determined in the ensilages. Variables were analyzed in a completely random design.

Nutritional blocks (NB) are a supplement strategy for ruminants, and regional food ingredients such as mango (Mangifera indica L.) are included in their preparation. Due to its rapidly fermentable sugars, mango pulp (MP) may be used to substitute sugar cane molasses in the elaboration of NB. The objective of the present experiment was to evaluate the kinetic of gas production in vitroand the fermentative characteristics of the partial substitution of sugar cane molasses (Saccharum officinarum L.) with MP in the elaboration of NB. The experimental design was completely
randomized and the treatments were MP0, MP10, MP20 and MP30, which was the level of substitution of molasses with MP. The variables determined in the sample of each treatment were: dry matter (DM), crude protein, ash, neutral detergent fiber (NDF) and acid detergent fiber (ADF).
