“…In the specialized dairy systems of Colombia, the predominant feed base is grazing of Kikuyu grass (Cenchrus clandestinus) and the use of supplementation with commercial concentrates, the latter representing a significant percentage of the total production costs (∼37%) (Cárdenas, 2003;Campuzano et al, 2018;Castillo et al, 2019). Kikuyu grass, although with good characteristics in terms of adaptability and productivity (biomass production), is affected by frost and grass bugs (Collaria scenica) (Campuzano et al, 2018). It also has nutritional limitations that can affect the production and compositional quality of milk, such as high levels of soluble nitrogen and low levels of non-structural carbohydrates (Correa et al, 2008).…”

“…It also has nutritional limitations that can affect the production and compositional quality of milk, such as high levels of soluble nitrogen and low levels of non-structural carbohydrates (Correa et al, 2008). In addition, the production systems based on Kikuyu are associated with deficient pasture management, mainly in terms of fertilization (Campuzano et al, 2018), and residual grass management, restricting both levels of production and productivity. This leads to impacts at the environmental level, since soil and water are being contaminated with nitrogen (N) that is not usable by the animal and released with the urine (given the levels of soluble N in Kikuyu, the inadequate management of grazing and low levels of supplementation) (J.…”

“…These studies have focused on seeking strategies for soil recovery and renovation of pastures, establishment and management of forage grazing systems, and production of forage crops for ruminant feeding systems (Castillo et al, 2019). Although there is no germplasm improvement and evaluation program specifically for the higher tropics, the research processes carried out by Agrosavia have led to the release of six oat cultivars in the country since the 1960s: ICA Bacatá (Avena fauta) (1963), ICA Soracá (Avena byzantina) (1965), ICA Gualcalá (Avena byzantina) (1968), ICA Cajicá (Avena sativa) (1976), Avena Obonuco Avenar (Avena sativa) (2003) and Avena Altoandina (AV25; High-Andean Oat) (2018) (Bustamante, 1965;Arias et al, 1972;Bolaños-Alomía et al, 2003;Campuzano et al, 2018). Despite its release over 45 years ago and the release of other cultivars thereafter, ICA Cajicá still predominates on the market and is one of the most used oats for animal feeding (through silage).…”

“…The cultivar Altoandina, released in 2018, is the most recent oat made available to dairy producers, and is the result of an evaluation process which began in 2005. Compared to the previously released materials and commercial oats used in the region, Altoandina stands out for its higher biomass production, better nutritional quality, and greater resistance to rust and overturning (Campuzano et al, 2018(Campuzano et al, , 2020, making it a promising alternative for supplying the forage deficit of the prairies in times of scarcity (drought) and improving the productivity of the specialized dairy systems in the Colombian higher tropics. In general terms, oats stand out as a forage crop widely used as a source of animal nutrition throughout the world, especially in European countries and the United States (Fraser and McCartney, 2004;Suttie and Reynolds, 2004;Harper et al, 2017).…”

“…The technical evaluation of oats in Colombia is being led by Agrosavia, which has focused on evaluating the effects of using it as a supplementation strategy in critical times (through silage) on the production and composition of milk in the higher tropics (Barahona et al, 2003;León et al, 2008;Mojica et al, 2009;Campuzano et al, 2018Campuzano et al, , 2020. Although variable effects on production have been reported, most of these studies have shown how the use of oats allows maintaining milk production stable when compared to feeding strategies solely based on Kikuyu grass (León et al, 2008;Mojica et al, 2009;Campuzano et al, 2018Campuzano et al, , 2020. Studies on the economic viability of including oat varieties in cattle systems were, however, not conducted yet for Colombia.…”

In the Colombian high-altitude tropics (2,200–3,000 m.a.s.l.), Kikuyu grass (Cenchrus clandestinus) is the main feed source for the dairy system. This grass species has good characteristics regarding adaptability and productivity, but is affected by frost, grass bugs (Collaria spp.) and precipitation-related production seasonality. Forage deficits might thus be a problem at several times in a year. As a strategy to maintain production stable, dairy farmers use commercial feed concentrates increasing their production costs. Agrosavia, as a response to this, started in 2005 with the evaluation and selection of new forage species for the Colombian high-altitude tropics. The oat Avena sativa AV25-T was identified as promising alternative to supply the requirements of dry matter in times of deficit and released as cultivar in 2018 under the name Altoandina. The objective of this study was to evaluate the economic viability of Altoandina in Colombia's high-altitude dairy systems. Altoandina (Aa) was provided as silage in two different diets: 35%Aa−65% Kikuyu (Yellow Diet) and 65%Aa-35% Kikuyu (Red Diet). The diet for comparison was traditional grazing with 100% Kikuyu grass (Blue Diet). All diets were supplemented with 6kg commercial feed concentrate, 0.5 kg cotton seeds and 0.5 kg Alfalfa meal per cow/day, respectively. To estimate economic indicators, we used a cashflow model and risk assessment under a Monte Carlo simulation model. Including Altoandina incremented productivity per hectare by 82.3 and 220% in the Yellow and Red Diets, respectively. According to the results of our economic model, the Yellow Diet is the best alternative. Its average Net Present Value (NPV) was superior in >80% and showed a lower variability. The indicators Value at Risk (VaR) and probability (NPV < 0) show the Yellow Diet to have the lowest risk for economic loss under different yield/market scenarios. The Yellow Diet also has the lowest unit production costs and uncertainty of productive parameters. According to our findings, supplementation with Altoandina at 35%, i.e., during critical times, has high potential to improve efficiency and profitability. This information is key for the decision-making process of dairy farmers on whether to adopt this technology.

La producción de semillas de cereales como la avena, la cebada y el trigo constituye una estrategia fundamental para promover la sostenibilidad de los sistemas de producción bovina en el trópico alto colombiano. En este contexto, el presente manual presenta las investigaciones y experiencias acumuladas por AGROSAVIA en el ámbito de la producción de semillas, con el objetivo primordial de incrementar la productividad y garantizar la calidad de la semilla, especialmente orientada a pequeños y medianos productores. El manual abarca de manera integral la descripción, generalidades, importancia y principales características de la avena, la cebada y el trigo. A continuación, se detalla el proceso de producción de semillas, desde la planeación del cultivo hasta el almacenamiento de esta, incluyendo la selección y preparación del terreno, el establecimiento del cultivo, su desarrollo y mantenimiento, la cosecha, la poscosecha y el almacenamiento adecuado de la semilla. Finalmente, el documento realiza un análisis exhaustivo de los costos de producción de semilla de acuerdo con el proceso descrito. Toda la información contenida en este manual se sustenta en la amplia experiencia e investigación desarrollada por AGROSAVIA en el campo de los cereales, con un enfoque particular en el altiplano cundiboyacense.
