“…In tropical conditions, especially in the Midwest region of Brazil, the forage production shows a marked variation over the year (ABOT et al, 2015). Thus, in hot and rainy months, there is availability of pastures in quantity and quality; however, in cold and dry months, fodder become mature and present decline in vegetative growth, reduction in protein, minerals and soluble carbohydrates, and increase in indigestible fiber content, due to the physiological process of lignification.…”

ABSTRACT:The aims of this study were to evaluate forage production and nutritional quality of the elephant grass, leucaena and pigeon pea beans, grown in monocrop or in intercropping systems in Cerrado / Pantanal ecotones in both, dry and rainy, seasons. Experimental design was completely randomized with five treatments and five repetitions. The treatments were: elephant grass, leucaena and pigeon pea all of these in monocrop; intercropping elephant grass with Leucaena; intercropping elephant grass with pigeon pea. During the rainy season, it was carried out three cuts at intervals of 60 days, and in the dry season a single cut with 180 days. In the rainy season, the biomass produced of the forages elephant grass, leucaena and pigeon pea corresponded respectively to 72, 64, 76% of the annual production. Under intercropping system, fodder behaves similarly, with the average of 72% of annual production. During this period, the nutritional quality of the forages was also higher than the dry season. In the dry period, there was decreased the production of biomass and a reduction in the proportion of leaves in all the forage, regardless of cultivation system. In both seasons (rainy and dry), the forage grown under intercropping system showed higher dry matter production in relation to monocrop system, with most of this production coming of elephant grass. The intercropping elephant grass with the pigeon pea has the highest production of dry matter, while the intercropping elephant grass with Leucaena has better nutritional quality.

The objective of this study was to assess the effect of cutting time on the nutritional composition and dehydration rate of stargrass, as well as the nutritional value of the hay as a function of storage time. Two plant cutting times were analyzed: at 13:00 (H13) and 17:00 (H17). After cutting, the dehydration rate of both the plant and its fractions until baling was monitored. The bales were checked for nutritional composition and digestibility after 30, 60, 90 and 120 days. At the time of cutting, a difference was observed for the concentrations of ethanol-soluble carbohydrates, which were higher for H17 (90.3 g kg-1) compared to H13 (52.9 g kg-1). Leaf dehydration rates were higher in the H17 treatment. Cutting time had no influence on the nutritional value of the hay. With storage time, there was an increase in the levels of neutral detergent fiber and acid detergent fiber, and a reduction in the content of ethanol-soluble carbohydrates. It was concluded that cutting at 17:00 allows for a greater accumulation of soluble carbohydrates in the plant. Cutting time does not change the time required for dehydration and the nutritional value of the hay. Storage time reduces soluble components and increases fibrous constituents
