Track 2-1-2: Forage Conservation, Value Addition and Balanced Nutrition
Description
Systems of ruminant production in the Andean highlands of Ecuador are dominated by monoculture grasses, where producers do not allow association with other plants such as weeds. These systems have small areas of land and the peasants would be wasting feed resources (association) with high nutritional content and secondary compounds that may be beneficial for feeding ruminants improving the nutritional value of grassland. In this context, Castelán et al. (2003) mention that the use of weeds in ruminant nutrition by small producers in temperate areas of Mexico, it becomes the main natural forage resource for livestock to feed round the year, as there great availability. For farmers with limited financial resources this practice is very common, because it represents feeding efficiency with low production costs, because they use non-conventional feed resources. Weed species such as Sicyos deppei G., Jaltomata procumbens (Cav.), Drymaria laxiflora Benth y Lopezia racemosa Cav. contain high levels of ruminal fermentation and high crude protein content, as well as low levels of fiber (Castelán et al., 2003). Under this background, the objective of this research is to determine the chemical composition and in situ ruminal degradation of weeds with forage potential that exist in the grasslands of the Andean highlands of Ecuador.
