“…The average CP content was 7.24% DM, which is close to that found by Buso et al (2018) in a study evaluating corn hybrids for silage. There was a significant difference between CP levels in the different cutting height treatments; this is different from what was observed by Marquardt, Jobim, Bueno and Ribeiro (2017), who, when working with silage corn harvested at 20 and 40 cm above the ground, did not observe any difference between the levels of CP; however, none of these treatments came from intercropping systems with forages.…”

“…There was no difference (P> 0.05) in NDF content due to the cutting heights, corroborating the findings of Marquardt et al (2017), who evaluated cutting heights of 20 and 40 cm above the soil surface. For the ADF, the elevation of the cutting height had a positive effect (P <0.05), since the silages from the cut at 45 cm from the soil showed more satisfactory ADF values.…”

The objective of this study was to evaluate the yield and nutritional value of silage made from corn intercropped with marandu palisadegrass (Urochloa brizantha cv. Marandu) in an integrated crop-livestock system. The corn was harvested at different maturity stages and cutting heights and was processed or not before ensiling. The experimental design was a randomized block with four replications in a 2x2x2+1 factorial scheme. The treatments were composed of silage corn intercropped with marandu palisadegrass harvested at two cutting heights (20 or 45 cm) and two stages of maturity (1/4 of the kernel milk line or kernel physiological maturity) and subjected to two methods of processing (crushing or not crushing). A control treatment composed of conventionally grown corn silage was also included. The total dry matter yields of both crops did not differ significantly among treatments, demonstrating the viability of the intercropping system for both forage species. Although the dry matter content of the corn plants was higher at the time of ensiling, the fermentative and nutritive quality of the silages was not affected. Increasing the cutting height increased the grain content of the forage mass and also avoided harming the development of the intercropped grass. The silages from the physiological maturity treatment and from the processed treatment had the best quality.

“…Maiores valores de CEL foram observados quando a adubação foi feita em área total. Mesmo comportamento foi observado em silagens de milho em diferentes alturas de corte e uso de inoculantes por Marquardt et al (2017). De modo geral, o conteúdo de fibras é um dos principais fatores que limitam o valor nutritivo da silagem (Krakowsky, et al, 2006).…”

O consórcio de milho com leguminosas pode aumentar a qualidade da silagem e resultar em maior produtividade animal. Objetivou-se nesta pesquisa avaliar aspectos agronômicos das culturas consorciadas entre milho e soja, perfil fermentativo e bromatológico da silagem produzida, em função do arranjo espacial das plantas e tipos de adubação. Foram realizados dois ensaios com dois arranjos espaciais: ensaio 1 – arranjo simples com uma linha de milho alternada com uma linha de soja; ensaio 2 - arranjo duplo com duas linhas de milho alternada com uma linha de soja. O delineamento foi em blocos ao acaso em esquema fatorial 2x2+1, com quatro repetições. O primeiro fator constou de duas modalidades de adubação de semeadura na linha: somente no milho e em área total. O segundo fator pelas doses de 100 e 70 kg ha-1 de P2O5 e K2O, respectivamente; e de 150 e 95 kg ha-1 de P2O5 e K2O, respectivamente. O monocultivo de milho foi a testemunha. Após a colheita, o material foi ensilado por 60 dias. Não houve diferença estatística no rendimento de silagem entre tratamentos, apenas aumentos na produção de vagens de soja e na qualidade da silagem nas doses maiores de adubação. Os resultados mostram que a adição de soja na silagem de milho ocasiona maiores perdas durante o processo de fermentação, mas em contrapartida eleva os teores de proteína, extrato etéreo e de digestibilidade. Ressalta-se que um volumoso com essas características pode vir a suprir a suplementação proteica em dietas de ruminantes.

“…It is possible to infer that the crude protein content of the silage suffers greater interference from the use of bacterial inoculants according to the stratum of the silo in which the silage is found. The similarity in the protein content between the strata of the silo is fundamental (Marquardt, Jobim, Bueno, & Ribeiro, 2017), mainly in properties that use small amounts of silage daily and do not have mixers.…”

The objective of this work was to evaluate the chemical composition and rumen disappearance rate of dry matter of corn silages with inoculants combining L. buchneri strain LN40177 in different strata of the silo. The experimental design was a 3x2 randomized complete block design, with three treatments: Control: corn silage without inoculant; 11CFT: corn silage with inoculant which combines L. buchneri strain LN40177 (1.1 x 1011 CFU g-1) with L. casei (1.1 x 1011 CFU g-1); and 11C33: corn silage with inoculant which combines L. buchneri strain LN40177 (1.1 x 1011 CFU g-1) with L. plantarum (1.1 x 1011 CFU g-1) and Enterococcus faecium (1 x 1010 CFU g-1), associated with two strata of the silo (lower and upper). The silage inoculated with 11C33 presented higher contents of crude protein and NDF and lower hemicellulose content in relation to the control treatment and 11CFT. The use of both inoculants resulted in silages with higher concentrations of soluble nutrients. Lower stratum silage had a higher rumen disappearance rate of dry matter compared to the upper stratum. In general, the combinations of L. buchneri promoted nutritional improvements in corn silage, but in presence of L. casei, there were more outstanding improvements.
