“…Segundo Calazans et al (2016), as estirpes de rizóbios da Cratylia argentea, otimizou a incorporação de biomassa e nutrientes em sistemas produtivos no cerrado. Hirai et al (2015) avaliaram ganho de peso de novilhos levando em consideração o uso de pastagem de aveia branca, consorciado com a leguminosa ervilhaca (Vica sativa) e com suplementação energética. Os resultados utilizando suplementação energética foram superiores; porém, o uso de pastagem consociada com leguminosa mostrou-se relevante, trazendo bons resultados quando avaliado ao uso apenas da pastagem, e sendo uma boa alternativa para minimizar custos, quando a suplementação se torna de alto valor.…”

A pecuária ocupa lugar de destaque na economia brasileira, principalmente a bovinocultura de corte e leite, assim o sucesso desse setor é primordial para o crescimento do país. Porém, a produtividade deste setor está intimamente ligada a qualidade das pastagens, pois essas são a principal fonte alimentar dos bovinos, e cerca da metade das pastagens brasileira encontra-se com algum grau de degradação, diminuindo assim a produtividade e rentabilidade desse setor. Devido a isso, a busca por tecnologias de recuperação de pastagens vem sendo pesquisadas, sobretudo as que diminuam os custos no processo de recuperação, procurando aumentar a produtividade e qualidade das pastagens, preservar o meio ambiente e maximizar os lucros para os produtores. Visto isso, o uso de novas fontes de adubação e a implantação de sistemas silvipastoris tem sido amplamente estudado e aplicado para recuperação dessas áreas, dentre eles podemos destacar o uso de biossólido que um adubo orgânico proveniente do tratamento de esgoto sanitário, assim como a implantação de pecuária-floresta utilizando Moringa oleífera uma planta leguminosa a qual fixa nitrogênio no solo e pode servir como fonte alimentar para os animais. Sendo assim, nesse trabalho está descrito o cenário da degradação e pastagens brasileiras e o uso de biossólido e moringa na recuperação dessas áreas.

“…Searching for more options, besides animal supplementation, the grass-legume mixed pastures have been widely used in ICLS, which are usually grown in the off-season after soybean (PIRES et al 2021). Hirai et al (2015) compared grass-legume mixture with animal supplementation and observed that the mixture is viable for beef cattle production, as it is possible to achieve intermediate results on animal performance, which is a good option when energy supplementation is costly.…”

Animal supplementation and grass-legume mixture can increase the stocking rate and crop and animal waste in the soil. Our hypothesis is that these alternatives can increase the amount of nitrogen recycled in an integrated crop-livestock system. We analyzed in an integrated croplivestock system, whether the nitrogen recycling and the soybean crops are influenced by legume and animal supplementation (1% live weight) in beef cattle production. We evaluated animal nitrogen intake, the recycled through feces and urine, and the amount of nitrogen retained in beef cattle carcass. In summer, the rate of dry matter, and nutrient release from the residual biomass after grazing and feces of animals, the export of nitrogen by soybean crops, and grain production. It was possible to increase the stocking rate in 21% through supplementation and with this there was a 33% increase in the return of nitrogen through feces and urine compared to the control. This result interfered with the export of nitrogen in grains, which was 9% higher in paddocks where there was animal supplementation. The amount of nitrogen exporting by the animals, in 90 days of grazing, did not differ between treatments, averaging 8.18 kg ha− 1 of N. Nitrogen return in a complete cycle increased by 19%, where animal and legume supplementation was used. We concluded that the supplementation and use of legumes are alternatives to increase the nitrogen recycled in integrated farming systems. Of the total N exporting, about 3 to 4% are through animals, and 96 to 97% are through soybean grains.

This study aimed to evaluate the effect of a mixture of temperate and legume grasses with or without energy supplementation on the performance and feeding behavior of finishing beef steers. Eighteen Nellore-Zebu steers, average 23 months old and body weight (BW) of 380 kg, were used in a continuous grazing system, in a randomized block experimental design. Treatments were ORS: oat (Avena strigosa Schreb) + annual ryegrass (Lolium multiflorum Lam) + supplementation with corn bran; ORVS: oat + ryegrass + vetch (Vicia sativa L.) + supplementation with corn bran; and ORV: oat + ryegrass + vetch. Evaluations were conducted on pasture (forage mass, sward height, herbage accumulation, botanical composition, and chemical composition) and animal (performance and ingestive behavior). Stocking rate and forage mass were greater in treatments with energy supplementation (ORVS and ORS), thus presenting greater sward heights compared to the treatment without supplementation. There was greater participation of oats and ryegrass when vetch was absent (ORS). The presence of supplement (ORS and ORVS) increased the presence of oat stem. The presence of the supplement caused the contribution of the vetch to be lower, likely because of the higher animal load of these treatments. The higher presence of vetch increased crude protein content in the ORV treatment. The ORS exhibited greater gain per area compared to the ORV. Supplemented animals had lower grazing and greater idle time. The ORS treatment animals spent more time in other activities and consumed supplementation and less time grazing than the other treatments. The absence of supplement (ORV) caused the animals to spend more time grazing. Animals not supplemented showed a higher duration of daily chewing, number of chews per minute, number of daily chews, daily number of bites, and station numbers.
