“…In the present study, an increase in LW and LL of M. maximus with the advance of the phenological stage was NDF content in blades increased from the first to the third cut, while ADF increased from first to second cut and then remained constant at the late stage except for the Vencedor genotype. These findings differ from those of Schnellmann et al 35 who reported significant increases in these parameters between different cutting intervals (30, 45, and 90 days). They mention that NDF is a fraction whose increase is associated with the advance of the phenological stage of the plant.…”

“…NDF and ADF content in stems increased from the first to the second cut and then remained constant at the late stage except for Vencedor and Mutale genotypes. Our results differ from those of Méndez-Martínez et al 34 and of Schnellmann et al 35 who found that these nutritional parameters increased as regrowth age advanced. In agreement with Stabile et al, 36 we observed genotypic variations for these nutritional parameters.…”

BackgroundMegathyrsus maximus is a forage grass native to Africa but widely cultivated in tropical and subtropical regions of the world where it is part of the grazing food chain. This study aimed to evaluate five M. maximus genotypes for the effect of maturity on their morpho‐agronomic traits, nutritional composition and digestibility, and to correlate their leaf blade and stem anatomy with their nutritional value.ResultsThe proportion of sclerenchyma tissues increased as maturity was reached, while lignin accumulation was differentiated between genotypes. Gatton, Green Panic and Mutale genotypes maintained their acid detergent lignin (ADL) values for leaf blades in the three cuts evaluated. In sacco ruminal dry matter disappearance was lower in Green Panic genotype at the vegetative stage for stems, but not for leaf blades. Significant positive correlations were found between dry matter disappearance and mesophyll tissues, and the latter were negatively correlated with neutral detergent fibre (NDF) and ADL.ConclusionOur results strongly indicate that cutting age and genotype affected the nutritional value of Megathyrsus maximus leaf blades and stems, with a more pronounced loss of quality in stems than in leaf blades. We recommend increasing the frequency of grazing at early stage or anticipating the stage of stem elongation in Green Panic to produce forage with better nutritional value.This article is protected by copyright.

En el trópico mexicano la ganadería está basada en sistemas de producción extensivos y es importante conocer el contenido nutricional de los forrajes, por ello el objetivo del presente estudio fue evaluar la composición química de: Cenchrus ciliaris L., Megathyrsus maximus cv Guinea, Ixophorus unisetus y Megathyrsus maximus cv Tanzania, gramíneas establecidas y utilizadas con frecuencia en el trópico para la alimentación animal. Las muestras provenientes del Rancho ‘San Luis Tenango’, Tonaya, Jalisco se analizaron en el Laboratorio de Nutrición Animal, Departamento de Zootecnia, Universidad Autónoma Chapingo. Se determinó: cenizas (Cen), proteína cruda (PC), extracto etéreo (EE), fibra detergente neutro (FDN), contenido celular (CC), fibra detergente ácido (FDA) y celulosa (Cel). El análisis de los datos se hizo con tres repeticiones y cada repetición se consideró una unidad experimental. Se realizaron la correlación de Pearson y la separación de medias por Tukey (p< 0.05). La PC resultó correlacionada positivamente con Cen y CC y negativamente con FDN y FDA (p< 0.05). Megathyrsus maximus cv Guinea fue la especie forrajera con mayor cantidad de PC (12.9 g (100 g)-1), seguida por (p< 0.05) Megathyrsus maximus cv Tanzania (8.7 g (100 g)-1). Megathyrsus maximus cv Guinea mostró el mayor porcentaje de Cen, 11.7 g (100 g)-1 y los valores más bajos valores de FDA y Cel y su valor de FDN (74.8 g (100 g)-1) fue bajo (p< 0.05), levemente superior al de Ixophorus unisetus (73.5 g (100 g)-1). Por tanto, Megathyrsus maximus cv Guinea fue la gramínea con mayor valor nutricional.

Megathyrsus maximus (Gatton panic) is a tropical grass highly valued both for its use as forage and for its biofuel potential. A major constraint in establishing pastures of this cultivar is the low viability and germination of seeds and the poor initial seedling establishment. We used non-thermal plasma (NTP, partially ionised gas) as a novel technology to treat seeds of this grass, aiming to improve their quality (i.e. germination traits). We also followed the performance of seedlings grown from NTP-treated seeds under field conditions by assessing seedling establishment, biomass production and forage quality during the first regrowth period, which is the critical period for pasture establishment. Two NTP treatments were performed through dielectric barrier discharges employing N2 as carrier gas. Non-treated seeds served as the control. Results showed that the viability of NTP-treated seeds was, on average, 1.5-fold higher than the control, and that germination energy and germination percentage of treated seeds was superior to the control by 2.1-fold and 2.2-fold, respectively. A field experiment showed that seedling establishment parameters (dynamics of cumulative emergence, emergence coefficient, and weighted average emergence rate) and pasture early productivity (represented by shoot dry matter) were enhanced by NTP treatment (phenolic sheet–polyester film barrier and 3 min exposure), showing 1.4–2.6-fold higher values than the control, confirming the results of the laboratory assays. Although NTP markedly increased the shoot dry matter production of the pasture, which was related to higher tiller population density and greater tiller weight, it did not affect the forage quality of the plants grown in the field. We conclude that NTP technology is suitable to improve seed germination of Gatton panic, in turn leading to improvements in seedling establishment and biomass production under field conditions without compromising forage quality.
