1. Nutritional, physicochemical and anatomical evaluation of creole corn varieties from the region of the Costa Chica of Guerrero
Abstract Corn (Zea mays) is the most consumed cereal in México, so it is necessary to know the nutritional and anatomical quality of the grains, which have been the main conservation and consumption criteria of the prehispanic peoples. This practice has allowed to preserve varieties of Creole corn, however, due to the lack of knowledge of these characterist

3. Evaluating early selection in perennial tropical forages
Abstract Perennial grass hybrids of Urochloa are evaluated for at least two years during the screening stage trials (SS) and advanced trials (AD) in breeding programs, an expensive and time-consuming process. In this study, we aimed to evaluate the potential for early selection of cultivars in this breeding scheme. We used multiple measurements of agronomic

5. Production and nutritive value of pastures in integrated livestock production systems: shading and management effects
ABSTRACT This study aimed to evaluate the production characteristics of pastures in integrated livestock production systems. For that, an experiment was carried out in São Carlos, SP, Brazil, from 2013 to 2015. Forage development, production and nutritive value were evaluated in five beef cattle production systems: extensive continuous stocking (Urochloa de

8. Productivity and nutritive value of elephant grass pastures under organic and conventional production systems
Abstract: Elephant grass (EG) (Pennisetum purpureum Schum.) have great importance in tropical and subtropical climates, especially on dairy farms. Normally, EG is established alone under high fertilization levels. EG in organic production system can improve low production costs and environmental issues, are still little known. The aim of this research was to

10. Canopy structure and forage nutritive value of elephantgrass subjected to different stocking rate and N fertilization in the “Mata Seca” ecoregion of Pernambuco
ABSTRACT The objective was to evaluate the effect of three stocking rates (2, 3.9, and 5.8 animal units ha−1) and three fertilization levels (0, 150, and 300 kg N ha−1 yr−1) on herbage mass and nutritive value of elephantgrass (Pennisetum purpureum Schum.) cv. IRI-381. The experiment was conducted from May to August of 2009 and 2010 in Itambé, PE, Bra

11. Evaluating rumen fermentation kinetics and nutritive value of sunflower seed meal supplemented with acetonic extract of pomegranate peel using in vitro gas production technique
ABSTRACT. This study was conducted to investigate effects of supplementing different levels (0.0, 0.5 and 1.0% of buffered rumen fluid) of acetonic extract of pomegranate peel on rumen fermentation kinetics of sunflower seed meal (SFM), using in vitro gas production technique. The samples were incubated in syringes containing rumen liquor obtained from three

12. Protein and carbohydrate fractionation of Jiggs Bermudagrass in different seasons and under intermittent grazing by Holstein cows
ABSTRACT. Jiggs bermudagrass has presented competitive production potential over other forages. However, there is a lack of information about the nutritional value of this forage with important relevance in ruminant nutrition. This study aimed to evaluate the protein and carbohydrate fractionation of Jiggs bermudagrass in different seasons of the year under
