“…During dry season Tobiatá,Mombasa,Tanzania,Vencedor,and Massai had 7.09,6.24,6.13,6.72, and 7.82% of protein content. These values were higher than those found in commercial cultivars in important tropical livestock areas (Costa et al, 2017Silva T.V.S et al, 2017Silva et al, 2018. However, in the same research location where the experiment took place, and with a similar number of recovery days and average height in Massai, obtained results were higher than 14.20% (Ruiz et al, 2015).…”

Background: Nutritional quality of forages is a strategy of continuous research in animal feeding to help mitigate the environmental impact generated by Tropical livestock. The aim of this study is to describe and classify the nutritional profile of the M maximus collection in Dry Tropics as a contribution to the selection of high-quality grassland for sustainable livestock production. The selection criteria were based in the potential of materials to mitigate climate change effects and to support plant breeding processes. For this, the nutritional composition of 129 CIAT accessions of Megathyrsus maximus was evaluated in representative cultivation conditions of Colombian Dry Tropical Forest by means of Near-Infrared Spectroscopy (NIRS) technique, Crude Protein (CP), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), and in vitro Dry Matter Digestibility (IVDMD) was determined with rainy and dry seasons as fixed effects. Results: genotype and precipitation affect the nutritional value. However, there is relative nutritional steadiness in the NDF, ADF, and IVDMD among seasons for some accessions. According to the nutritional composition index (ICN), half of the evaluated collection had nutritional potential. From this group, 15 accessions showed higher values during rainy and dry seasons. Conclusions: M. maximus has an adequate nutritional profile for animal feeding in dry tropics agroecosystems. It generates alternative materials to project and sustain eco-efficient livestock production in the tropics.

These values were higher than those found in commercial cultivars in important tropical livestock areas (dos da Silva et al, 2018). However, in the same research location where this experiment took place, and with a similar number of regrowing days and average height in Massai, Ruiz et al (2015) showed 14.20% CP.…”

The diversity and use of tropical forages for cattle feeding are the protagonists in livestock systems. The production and nutritional quality of forages represent a strategy of continuous research in animal feeding to help mitigate the environmental impact generated by tropical livestock. The objective of this study was to classify the nutritional behavior in contrasting seasons and the relationship with agronomic traits of a collection of 129 CIAT (Centro Internacional de Agricultura Tropical) accessions of Megathyrsus Maximus established in the Colombian dry tropics. By means of the near-infrared reflectance spectroscopy (NIRS) technique, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and in vitro dry matter digestibility (IVDMD) were determined under rainy and dry seasons as fixed effects. We measured plant height, dry matter biomass (DMB) and flowering in field. Aspects such as plant height and DMB did not show correlation with nutritional aspects, whereas flowering was correlated with the content of structural carbohydrates. Despite genotype and precipitation affecting nutritional value, there is relative nutritional steadiness in NDF, ADF, and IVDMD between seasons for some accessions. According to the cluster analysis carried out for each season, it was evidenced that from the total collection, 51.2% of the accessions during the dry season and 19.4% of the accessions during the rainy season were classified with a better nutritional profile, thus, showing a higher number of materials with better nutritional behavior in the dry season. Both the genotypic characteristics of M. maximus and environmental conditions during contrasting seasons are factors that might influence the variability of the nutritional content, productive parameters, and flowering. Additionally, fodder material classification under Hotelling's T-squared test and Nutritional Classification Index suggests accessions that might be promising for resilient nutritional quality and adequate DMB, which proves that M. maximus could become an alternative for animal feeding and sustainable livestock production during critical dry periods in tropical agroecosystems.
