ABSTRACT This survey was conducted to assess the fermentation profile and nutritional composition of tropical grass silages on beef farms. Grass silage samples were collected from 51 beef cattle operations located in four Brazilian states (MT, MS, SP, and PR). Additionally, a questionnaire about silage production and utilization was completed. The lack of correlation between the concentration of n-butyric acid and the IVDMD (P = 0.368) indicated that fermentation pattern and nutritional value were independent and therefore required separate grouping […]

The objective of this experiment was to evaluate the effects of nitrogen doses (0, 100, 200, 300, and 400 kg ha-1 year-1), with or without dolomitic lime covering application, on the potassium (K) soil content at depths varying form 0 to 5, 5 to 10, and 10 to 20 cm, and the potassium concentration in the plant. The experiment was carried out in a rhodic ferralsol with a slightly rolling relief, in a 5 × 2 factorial arrangement, in a […]
