Herbage Mass, Forage Accumulation and Nutritive Value of \u3cem\u3eBrachiaria decumbens\u3c/em\u3e in a Silvopastoral System
The use of silvopastoral systems has been suggested to ensure sustainability in animal production systems because of their potential to increase soil fertility, improve forage quality, promote animal thermal comfort and provide income diversification for the producer (Paciullo et al. 2011). Nevertheless, the shade provided by trees may affect plant growth and nutritive value of forage (Sousa et al. 2010).
This study aimed to assess the impact of shading on the allocation pattern of dry matter and on herbage nutritive value, under various shading regimes, in a silvopastoral system, during both the dry and rainy seasons
Simulation and risk analysis of the use of elephant grass silage cultibrate BRS CapiaƧĆŗ compared to corn silage for dairy cows.
Given the high production of dry matter that can be obtained by the cultivar BRS CapiaƧu compared to corn for silage, there is a great economy of area used. with the BRS CapiaƧu cultivar, in addition to its perenniality. Even when ensiled with corn meal, the silage of the BRS CapiaƧĆŗ cultivar remains competitive in relation to corn silage, and can be used for cows producing around 30 kg of milk/day without any loss in production, provided that supplemented with well-formulated concentrates. It was observed that the silage-based system of the BRS CapiaƧĆŗ cultivar, added to corn meal produced a net profit at present value/hectare/year, three and a half times greater than the system based on corn silage. Risk analyzes showed that investment in the BRS CapiaƧu cultivar does not offer risks when replacing corn silage
