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.

Use of a cashew nut shell liquid resin as a potential replacement for phenolic resins in the preparation of panels - a review

The Cashew Nut Shell Liquid (CNSL) can be considered as a versatile raw material with wide applications in the form of surface coatings, paints and varnishes, as well as the production of polymers. Within this context, the chemical constituents of CNSL (anarcadic acid, cardanol, 2-cardol and methylcardol) become promising in the development of new materials components. Once separated, CNSL can be used in the research and development of additives, surfactants, pharmaceuticals, pesticides, polymers, resins and others. Being a byproduct, CNSL used in the preparation of new materials is characterized as a truly technological innovation.

Valor nutricional de silagem de capim-mombaça com aditivos agroindustriais

It was aimed to evaluate the chemical composition of grass silage-mombasa associated with different additives in four times of opening the silo. The experiment was conducted in UFGD. After harvesting the forage, biomass in natura crushed, was taken to the lab, homogenized and enriched on the basis of natural mass, with the following additives: 5% wheat bran, 5% of waste (broken grain and soy ice cream cone) of soybean, 5% urea in natural matter and the witness (without additive). The silos were opened after (unprocessed material), 15, 30 and 45 days, for the analysis of chemical composition. The data obtained were analyzed through the statistical programme SISVAR and averages were compared to 5% of probability, by Skott-Knot. The grass silage-mombasa without additive presented major (P<0.05) dry matter content compared to other treatments at time 0 and 30 days of silage and did not differ (P>0.05) of grass silage- mombasa associated with 5 of urea in 15 days and 45 of silage. The grass silage-mombasa with 5% urea showed the highest crude protein content at time 0 and differed from other treatments. The silage of mombasa associated with 5% urea provided greater in vitro digestibility of dry matter to 15 days of silage.

Comportamento ingestivo de novilhas Nelore em pastejo recebendo suplemento a base de própolis ou monensina sódica

We evaluated the effect of additives the basis of propolis and monensin on ingestive behavior (grazing -GRA, rumination lying -RLY, rumination in foot -RFO, rumination -RUM; idleness lying -ILY, idleness in standing -IDS, idleness -IDL, walking -WAL, posture standing -POS, posture lying -PLY, intake of supplement and water -ISW) of heifers in Tifton 85 grazing. The treatments were: no additive (NAD); propolis - PRO (33.24 mg animal-1 of total flavonoid in apigenin), and monensin -MON (100 mg animal(-1)). Were used five heifers treatment(-1) for evaluation of ingestive behavior during 12 hours of total valuation, which was divided into three periods. Used a factorial design into 3 x 3 for evaluation of ingestive behavior as a function of the evaluation periods. Were utilized three paddocks of 2.9 acres of grass Tifton 85. The additives and mineral supplement (50 g animal(-1)) were provided with 200 g of corn meal to 17 hours. For all activities of the ingestive behaviors observed the effect of period on the time spent on of different activities. The activities of GRA and ISW were higher in the third period (15hours to 19hours) compared to the first period (7hours at 11hours). For IDL and PLY, there was a higher time in minutes for heifers treatment with PRO in the period of 7hours at 11hours, compared to other treatments (NAD and MON). Thus, it is concluded that the use of the additive based on propolis enables sodium monensin replacement, to heifers maintained on pasture without changing eating behavior as well as providing greater idleness during the day the without affecting animal performance.
