“…According to Kebede et al [67], the most significant factor affecting DM production of Napier grass is the environment, followed by genotype by environment interactions and then the genotype. However, the genotype is still important and the DM yield of Napier grass has been demonstrated to be superior to other tropical forages including Guinea grass (Megathysus maximus) and Rhodes grass (Chloris gayana) [68].…”

Napier grass (Pennisetum purpureum Schumach.) is a fast-growing perennial grass native to Sub-Saharan Africa that is widely grown across the tropical and subtropical regions of the world. It is a multipurpose forage crop, primarily used to feed cattle in cut and carry feeding systems. Characterization and diversity studies on a small collection of Napier grasses have identified a moderate level of genetic variation and highlighted the availability of some good agronomic traits, particularly high biomass production, as a forage crop. However, very little information exists on precise phenotyping, genotyping and the application of molecular technologies to Napier grass improvement using modern genomic tools which have been applied in advancing the selection and breeding of important food crops. In this review paper, existing information on genetic resources, molecular diversity, yield and nutritional quality of Napier grass will be discussed. Recent findings on characterizing disease resistance and abiotic stress (drought) tolerance will also be highlighted. Finally, opportunities and future prospects for better conservation and use arising from the application of modern genomic tools in Napier grass phenotyping and genotyping will be discussed.

“…Grass species in the study areas showed no differences in ADF and NDF content, which fell within the ranges of 363-715 g/kg and 684.7-814.9 g/kg, respectively. According to Kebede et al [4], high ADF and NDF content, coupled with lower CP content indicate grass species of low nutritive value. Both ADF and NDF values in the current study fall within the range reported by Evitayani et al [58] for mature grasses.…”

“…Usable communal rangelands continue to shrink due to overgrazing-induced degradation as well as conversion to other uses, such as crop production [1,2]. The reduction in size and health of communal rangelands negatively affects livestock productivity, which manifest as weight losses, delayed calving and high levels of mortality [3,4]. The functional and operational management systems for communal rangelands are reportedly limited by a lack of empirical data to support decision-making [5].…”

Contribution of Soil Type to Quantity and Nutritional Value of Grass Species on the South African Highveld

The biggest threat to cattle production in most South African communal areas is poor management of grazing, which negatively affects vegetation and soil structures. This study was conducted to assess the spatial variation of grass species density, production potential and quality in Breyten (Hutton soil type), Davel (Avalon soil type), and Wesselton (Clovelly soil type) communal rangelands in the highveld region of Mpumalanga province. Three 100 m transects per grazing area, placed at 50 m intervals (0, 50, and 100 m) were used to collect soil samples at 200 mm depth. A 100 m permanent line point method, replicated three times (50 m apart) per site, was used to identify and collect grass species samples. Grass species were classified according to life form, palatability, ecological status, and abundance. Grasses species were also harvested for chemical composition and in vitro ruminal dry matter degradability determination. Soils from the study areas had an acidic pH range (3.5–4.5). Hutton soil had the highest (p < 0.05) nitrate (N-NO3) concentration (0.770 mg/kg) compared to Clovelly (0.030 mg/kg) and Avalon (0.533 mg/kg) soil types. Thirty-one grass species composed of 28 turf perennials, two weak perennials and one perennial creeping grass were identified across the study areas. About 16% of identified grass species were classified as highly palatable, 39% as moderately palatable, and 32% as unpalatable. Across all the soil types, Digitaria eriantha had the highest (p < 0.05) crude protein (CP) (106.5 g/kg DM) content when compared to other grass species. In the Avalon soil type, D. eriantha had the lowest (p < 0.05) neutral detergent fiber (NDF) (696.4 g/kg DM). Across all soils, D. eriantha, Aristida congesta, Eragrostis curvula, Eragrostis gummiflua, and Eragrostis plana grasses had the same (p > 0.05) 48-h in vitro ruminal dry matter degradability Hutton soil had a higher proportion of common and dominant grass species as well as more palatable species with higher crude protein content than Avalon and Clovelly soils. However, for all three rangelands, there is a need for supplementary feeding to enhance the production efficiency of livestock given that the nutritive value of grasses was low.

“…Por otro lado Nava et al, (2013) evaluaron el rendimiento y composición química del pasto Pennisetum purpureum establecido a dos densidades y en dos fechas de siembra diferentes, encontraron una digestibilidad in vitro de la materia orgánica que varió entre 62.7 y 64.9%, valores que también resultaron mayores en comparación con lo encontrado en el presente estudio. Kebede et al, (2016) Recientemente Vega, (2016) realizó un estudio en el cual buscó establecer el mejor método para la determinación de la digestibilidad y la determinación de la composición química de cinco pajas de mayor uso en los sistemas de producción de leche en pequeña escala del noroeste del Estado de México, encontrando una correlación positiva entre la técnica de incubación con líquido ruminal y la técnica de digestibilidad enzimática, por lo tanto el autor concluyó que no existen diferencias significativas en cuanto a la comparación de ambas técnicas (P>0.05). El promedio obtenido de digestión en la técnica de incubación con líquido ruminal fue de 515 g/kg MS en contraste a la técnica de digestibilidad enzimática en donde el resultado fue de 520 g/kg MS. Posada et al, (2012) Desde otra perspectiva Noguera et al, (2011) compararon el líquido ruminal vacuno y caprino como fuente de inóculo en la técnica in vitro producción de gas, sin encontrar diferencia estadística (P>0.05) entre los dos, en cuanto a la cinética de degradación de la materia seca y la materia orgánica.…”

Comparación de la digestibilidad de tres especies forrajeras estimada mediante diferentes técnicas 15 ARTÍCULO ORIGINAL/ORIGINAL ARTICLE Comparación de la digestibilidad de tres especies forrajeras estimada mediante diferentes técnicas Comparison of the digestibility of three forage species estimated by different techniques Comparação da digestibilidade de três espécies forrageiras estimadas por diferentes técnicas AbstractThis research was conducted in the Villavicencio city, at the Universidad de los Llanos, whose objective was to determine the digestibility of three forages for cattle through four different techniques: one in situ and three in vitro (inoculation with ruminal fluid, gas production, and enzymatic), in order to validate the techniques and equipment that are being used for these procedures; the forage species were evaluated: Pennisetum purpureum, Hibiscus rosa-sinensis y Gliricidia sepium, in addition it was evaluated both in all techniques: the curve and rate of degradation of dry matter (DM), neutral detergent fiber (NDF) and crude protein (PC) (0 to 72 hours). A repeated measures design was used, under which the analysis of variance was performed to determine the ranges of deviation between the techniques and thus establish the trend of the data; the variables evaluated were the digestibilities of DM, NDF and PC of the three forages of the four techniques; after verifying the differences between the variances of the digestibilities, and check the assumption of sphericity with the Mauchly test, the multiple comparison was performed with the Bonferroni test. The digestibility of DM, NDF and PC varied and 42.00-66.54% respectively in the PP, HR and GS forages, depending on the technique used for their estimation. Despite finding statistically significant differences among several of the comparisons made in the techniques of digestibility, it was found a high determination coefficient and correlation between estimates in vitro: inoculation with ruminal fluid, gas production and enzymatic with respect to the in situ estimate.
