Protein and carbohydrates fractionation in Paiaguas palisadegrass intercropped with grain sorghum in pasture recovery

Abstract

Paiaguas palisadegrass was released in order to meet the requirements of the different production systems. However, little is known about the quality of the forage. The goal of this study was to evaluate the protein and carbohydrate fractionation of the Paiaguas palisadegrass after intercropping with grain sorghum in the pasture recovery, through the integration of crop and livestock production. The experiment was conducted in the municipality of Rio Verde, State of Goias. The experimental design was a randomized complete block design with four replications. The treatments were composed of the following forage systems: Paiaguas palisadegrass in monocropped, sorghum intercropped with Paiaguas palisadegrass in the row, sorghum intercropped with Paiaguas palisadegrass in the interrow, and sorghum intercropped with oversown Paiaguas palisadegrass. The evaluations were carried out in the four climatic seasons of the year (winter, spring, summer, and fall) in the same plots, over a period of one year, in 16 paddocks under continuous stocking system. The results showed that forage systems did not influence protein and carbohydrate fractionation. The winter season presented higher values of protein and carbohydrate fractionation, negatively affecting the animal performance.

Effects of nitrogen fertilization on protein and carbohydrate fractions of Marandu palisadegrass

“…The NFC fraction can be rapidly degraded in the rumen, and is necessary to maintain adequate carbohydrate and protein degradation synchrony, and promote adequate microbial growth 17 . Variations in climatic conditions, such as precipitation, alter the production of leaves and stems, and, consequently, cause changes in the concentrations of soluble sugars, starches, and pectins 22 . Our results are in agreeance with those of Santos et al 22 , who observed high NFC when the highest precipitation occurred.…”

“…To apply the CNCPS to forages, it is necessary to characterize carbohydrates and N fractions 10 , 11 . Previous research has characterized protein fractions of various forage species from temperate areas 12 , 20 , including warm grasses [such as bermudagrass, stargrass, and bahiagrass] 21 and guinea grass 22 . However, information related to the effects of N fertilization and annual changes in the carbohydrate and protein fractions of Brachiaria is limited.…”

Chemical and Mineral Composition, Kinetics of Degradation and in vitro Gas Production of Native Cactus

“…The determination of the minerals, fractions of carbohydrates and proteins and the kinetic parameters of ruminal degradation is of utmost importance for nutritionists (Kalegowda et al, 2015;Alves et al, 2017). This information can be used in modern feed formulations for ruminants to maximize the synchronization of degradation of carbohydrates and nitrogen compounds, minimizing energy and nitrogen losses due to ruminal fermentation and promoting a greater efficiency of microbial synthesis (Boufennara et al, 2016;Santos et al, 2019). Therefore, it is necessary to further study the fractions of chemical components of such foods and the kinetics of degradation of the compounds present in such plants to optimize their use for the diet of ruminants.…”

SEMILLAS DE Brachiaria ruziziensis EN DIFERENTES TIEMPOS Y NIVELES DE MEZCLA CON UREA PARA LA FORMACIÓN DE PASTO

“…INTRODUCCIÓN Los sistemas de integración cultivo-ganadera representan una alternativa de producción racional para suelos pobres, como los arenosos. Entre los tipos de sistemas integrados se encuentra la asociación de plantas graníferas o ensiladoras, como el maíz y el sorgo, en combinación con plantas forrajeras, especialmente las brachiarias para la generación de pastos o rastrojo en labranza de conservación (FREITAS et al, 2018;COSTA et al, 2018).…”

“…Entre los factores, se encuentra el tiempo de contacto de las semillas con los fertilizantes, ya que cuanto mayor es la exposición de las semillas, mayor es el proceso de pérdida de calidad fisiológica (MATEUS et al, 2007;CODOGNOTO et al, 2019). Se pueden citar otros factores, como el fertilizante utilizado y sus cualidades intrínsecas, como el nivel de salinidad, las condiciones ambientales de almacenamiento de mezcla (temperatura y humedad del aire), la calidad fisiológica y física inicial de los lotes de semillas, la presencia y calidad de la cobertura de semillas (BEWLEY et al, 2013;SILVA et al, 2018;JOHANN et al, 2019).…”
