Offered Papers Theme A: Efficient Production from Grassland
Description
Annual ryegrass (Lolium multiflorum) swards are being used increasingly in Southern Brazil as animal forage (Carvalho et al., 2001). As observed elsewhere, reduced forage availability and quality during dry or cold seasons often limits the efficacy of pasture utilisation. As reported by Meissner et al. (1992), this demands breeding efforts to improve forage nutritive value. However, lack of concurrent examination of large number of samples for important nutritional parameters, like water-soluble carbohydrate (WSC) levels, which could lead to more precise selection strategies, is a common constraint of those programs. This study aimed to verify the suitability of using autoclave-assisted WSC extraction for concurrent screening of seedlings of annual ryegrass genotypes, aiming to establish early selection criteria.
