<b>Technical and economic viability and nutritional quality of mombasa guinea grass silage production

Abstract: ABSTRACT. The objective of this study was to evaluate the viability of pasture with high production capacity and the potential for production of silage using different sources and doses of nitrogen (N) by quantifying the productivity of dry matter (DM), some qualitative characteristics, the total cost of production (TC) and total operating cost (TOC) of silage production. The experimental design was randomized block in a factorial scheme with four replications including two sources of nitrogen (urea and ammoni… Show more

“…Tropical grasses, such as Mombasa guinea grass, can produce very high seasonal forage surplus, as observed in this study, with the average DMY in summer and autumn more than double winter production and 30% more than spring production. These seasonal surpluses could either be made into silage for feeding in winter and spring or fenced off to provide standing hay for feeding in the months of forage shortage (Galindo et al 2018).…”

“…However, forage plants are usually not fertilized and over time pasture decline occurs with reduction in both quality and quantity of forage (Silveira et al 2015). Most Brazilian pastures show some degradation degree, as and little technology is adopted, especially in the Cerrado region, where approximately 40% of the Brazilian livestock population is concentrated (Dupas et al, 2016;Galindo et al 2018). The use of pasture fertilization practices has resulted in higher performance indices (1) Ŷ =10,972 + 4.53x (R 2 = 0.86**); (2) Ŷ = 9,290 + 4.50x (R 2 = 0.65*); (3) Ŷ =4,055 + 2.10x (R 2 = 0.84**); (4) Ŷ =7,291 + 11.13x -0.01x 2 (R 2 = 0.97**); (5) Ŷ = 30,995 + 7.61x -0.002x 2 (R 2 = 0.96**); (point of maximum) PM = 1903 kg N/ha, 159 kg/ha/cut and 477 kg/ha/season; and (economical dose) ED = 1,383 kg/ha, 115 kg/ha/cut and 345 kg/ha/season).…”

“…A pecuária é uma importante fonte de renda para a população rural nos países do Hemisfério Sul, contribuindo para ao aumento da renda através da produção de carne, leite e couro (ZHANG et al, 2018). No Brasil, as pastagens são de extrema importância para a produção de carne bovina, e ocupam uma ampla extensão do território do país, cerca de 180 milhões de hectares (GALINDO et al, 2018). Elas são consideradas a base da alimentação dos bovinos e o meio menos oneroso para produzir proteína para o consumo humano GUERRA et al, 2018).…”

“…Atualmente aumentou a competição pelo uso da terra entre os usos pecuário e agrícola, na busca por melhor retorno sobre o capital investido. Assim, buscam-se tecnologias complementares de produção para integrar benefícios aos sistemas produtivos (GALINDO et al, 2018). O uso de fertilizantes pode aumentar significativamente a produção de forragem, a taxa de lotação animal e o ganho de peso ou a produtividade de leite por vaca, resultando no aumento da produção de carne e leite por unidade de área.…”
