- Nutritional value of dual-purpose wheat genotypes pastures under grazing by dairy cows Mauricio Pase Quatrin Clair Jorge Olivo Vinicius Felipe Bratz Vinicius Alessio Fabiene Tomazetti dos Santos Priscila Flores Aguirre Agrociencias winter cereal digestibility crude protein nitrogen uptake Triticum aestivum In the south of Brazil, one of the major limitations to milk production is the low forage availability during autumn and early winter. The use of dual-purpose wheat genotypes is one alternative to minimize the impact of low forage availability in addition to produce grains. Therefore, this study aimed to evaluate the nutritional value of two dual-purpose wheat genotypes (BRS Tarumã and BRS Umbu). Structural composition and forage nitrogen uptake were evaluated. The nutritional value of the forage was analyzed for mineral matter (MM), organic matter (OM), neutral detergent fiber (NDF), crude protein (CP), total digestible nutrients (TDN), in situ organic matter digestibility (ISOMD) and in situ dry matter digestibility (ISDMD). Differences in NDF (49.03 vs. 46.44%), CP (24.4 vs. 27.4%), ISOMD (83.53 vs. 85.45%), ISDMD (83.59 vs. 86.65%) and TDN (75.37 vs. 78.39) for BRS Umbu and BRS Tarumã genotypes were detected, respectively. The BRS Umbu genotype had a lower leaf blade proportion and forage nitrogen uptake. The dual-purpose wheat genotype BRS Tarumã was superior in nutritive value. 2017 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303153751012 https://www.redalyc.org/journal/3031/303153751012/ https://www.redalyc.org/journal/3031/303153751012/html/ https://www.redalyc.org/journal/3031/303153751012/303153751012.epub https://www.redalyc.org/journal/3031/303153751012/movil 10.4025/actascianimsci.v39i3.34420 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
