What is the best additive to use at the ensiling of sugarcane SP81-3250?

Our objective was to determine the best additive to use for the ensiling of sugarcane SP81-3250 based on the nutritional properties and aerobic stability of the silages. The additives evaluated were (1) and (2): salt (NaCl) at rates of 1.0 or 2.0 kg/100 kg fresh sugarcane (as-is basis), respectively; (3) and (4): quicklime (CaO) at rates of 1.0 or 2.0 kg/100 kg fresh sugarcane, respectively; (5) and (6): commercial inoculants Silobac (R) and Maize All (R); and a control treatment. The addition of quicklime reduced the NDF and ADF contents of the silages by 11% compared with the control treatment, but did not increase the digestibility. On the other hand, after 24 h of in vitro fermentation, the application of 1.0 and 2.0% salt reduced the gas production by 34.15 and 33.55 mL/g OM, respectively, and the IVOMD was reduced 5.74 and 5.90%, respectively, compared with the untreated silage. Moreover, the addition of quicklime elevated the pH of the sugarcane silages, with a trend towards an increase in the DM recovery. In contrast, the bacterial inoculants did not alter the pH values, but there was an upward trend for a DM recovery. After the silos were opened, the silages that were treated with salt (independent of the dose) and 1.0% quicklime exhibited greater stability. We recommend applying 1.0 kg of quicklime to each 100 kg of sugarcane at the time of ensiling to improve the nutritional characteristics of sugarcane silage variety SP81-3250.

Consumo, digestibilidade e balanço de nitrogênio de cordeiros alimentados com alto teor de amido ou fibra solúvel em detergente neutro associados ao óleo de girassol

The aim of this study was to evaluate the effect of different carbohydrate sources associated with sunflower oil on intake, digestibility of nutrients and nitrogen balance in diets of lambs. Twenty lambs were used, assigned in a completely randomized design with a 2 x 2 factorial arrangement of treatments with two sources of neutral detergent soluble carbohydrate, starch and neutral detergent soluble fiber, with and without the inclusion of 4.2% sunflower oil. The dry matter intake was not affected by carbohydrate sources and the inclusion of oil. Diets with a high percentage of starch provided higher digestibility of dry matter, starch and ether extract. The different sources of carbohydrates had no interference on digestibility of organic matter, crude protein, neutral detergent soluble fiber, nonfiber carbohydrates, neutral detergent fiber, hemicellulose and acid detergent fiber. The addition of oil in the diets increased the digestibility of ether extract. The combination of 4.2% oil in the diet high in soluble neutral detergent fiber had no influence on the nutrient digestibility, otherwise, the addition of oil at high starch diet caused a significant reduction in the digestibility of organic matter, neutral detergent fiber, hemicellulose and nonfiber carbohydrates. The quantities of nitrogen intake, absorbed and retained, did not differ as sources of carbohydrates and oil inclusion in the diet. The association of 4.2 % sunflower oil to the different sources of carbohydrates in the diet does not affect consumption and nitrogen metabolism in lambs. The addition of 4.2 % oil in the diet with high starch (28% of DM diet) promotes reduction in digestibility of organic matter, of fibrous and nonfibrous carbohydrate in the diet.
