“…The values implying better nutritional value for the forage, including higher CP and TDN concentrations and lower NDF as observed in the winter, are associated with the presence of ryegrass during the vegetative period. The mean CP, TDN and NDF values were 160, 560 and 680 g/kg DM, respectively, which are similar to values obtained in the same region, with ryegrass overseeding on Coastcross-1 bermudagrass (Diehl et al ., 2014). For the CP of Tifton 85 bermudagrass in the summer, the season in which this pasture was predominant, the mean value between grazing systems, 139 g/kg DM, was lower than that observed in a study in which this grass was mixed with forage legumes (Olivo et al ., 2019).…”

The inoculation with Azospirillum brasilense has the potential to reduce the use of mineral fertilizers with efficient capacity to promote plant growth and yield. Most studies on the Azospirillum–plant association have been conducted on cereals and annual grasses. More studies are needed in perennial pastures, such as bermudagrass (Cynodon dactylon (L.) Pers.) that require substantial nitrogen (N) fertilization to maximize their production potential. Therefore, pastures based on Tifton 85 bermudagrass in association with annual ryegrass (Lolium multiflorum Lam.), which were inoculated with A. brasilense and fertilized with increasing amounts of N fertilizer and grazed by lactating Holstein cows were evaluated. Three grazing systems were evaluated: (i) Tifton 85, inoculated + 180 kg N/ha per year; (ii) Tifton 85 + 230 kg N/ha per year; and (iii) Tifton 85 + 280 kg N/ha per year. Forage samples were collected before and after grazing to evaluate the responses of the plants and animals. The forage yields of the systems were 21.0, 20.8 and 22.1 t DM/ha per year and the stocking rates were 3.9, 3.8 and 4.0 animal unit/ha per day, respectively. Crude protein, total digestible nutrients and neutral detergent fibre concentrations were 162, 560 and 667 g/kg, respectively. Inoculation in pastures planted with Tifton 85 bermudagrass in combination with ryegrass (plus 180 kg N/ha per year) had a positive effect, providing forage yield and nutritional value equivalent to those with fertilization with 230 kg N/ha per year.

“…Após 36 meses a serapilheira e a pastagens começaram a ser coletadas mensalmente durante 1 ano e submetidas a avaliação de produtividade e o teor de nutrientes: N, P, K, Ca, Mg e S. Exceto o P, todos outros nutrientes tiveram maior deposição nos tratamentos em sistemas agrossilvipastoris, com destaque para os tratamentos com o plantio de acácia que promoveu maior deposição de N no solo, mostrando que a espécie leguminosa aumenta a produção de serapilheira e de nutrientes no solo, sendo mais eficiente na recuperação e manutenção de pastagens degradadas. Diehl et al (2014) avaliaram três diferentes sistemas agrossilvipastoris: capim elefante (CE) + azevém (AZ) + espécie de crescimento espontâneo (ECE), CE + AZ + ECE + amendoim forrageiro (AM) e a terceira CE + AZ + ECE + trevo vermelho (TV). Foram coletadas amostras de pastos simulando o pastejo para determinar os teores de proteína bruta (PB), fibra em detergente neutro (FDN), digestibilidade in situ da matéria seca (DISMS) e da matéria orgânica (DISMO).…”

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.

Plant and animal responses of elephant grass pasture-based systems mixed with pinto peanut

The effects of growing pinto peanut mixed with elephant grass-based pastures are still little known. The aim of the current research was to evaluate the performance of herbage yield, nutritive value of forage and animal responses to levels of pinto peanut forage mass mixed with elephant grass in low-input systems. Three grazing systems were evaluated: (i) elephant grass-based (control); (ii) pinto peanut, low-density forage yield (63 g/kg of dry matter – DM) + elephant grass; and (iii) pinto peanut, high-density dry matter forage yield (206 g/kg DM) + elephant grass. The experimental design was completely randomized with the three treatments (grazing systems) and three replicates (paddocks) in split-plot grazing cycles. Forage samples were collected to evaluate the pasture and animal responses. Leaf blades of elephant grass and the other companion grasses of pinto peanut were collected to analyse the crude protein, in vitro digestible organic matter and total digestible nutrients. The pinto peanut, high-density dry matter forage yield + elephant grass treatment was found to give the best results in terms of herbage yield, forage intake and stocking rate, as well as having higher crude protein contents for both elephant grass and the other grasses, followed by pinto peanut with low-density forage yield + elephant grass and finally elephant grass alone. Better results were found with the grass–legume system for pasture and animal responses.
