The objective of this study was to evaluate the effects of the addition of different percentages of urea or calcium oxide (CaO) on the fermentative characteristics and chemical composition of the by-product of sweet corn silage, without whole kernel corn. The experimental design was completely randomized in a 2 × 5 factorial scheme, with two additives (CaO or urea) and five inclusion levels (0, 0.5, 1.0, 1.5, and 2.0% in natural matter of by-product of sweet corn silage). There was interaction between the type of additives and addition levels (CaO or urea) for pH values (P < 0.05). The mean pH values ranged from 3.40 to 5.36 in the additive silage. For effluent production, the additive type interaction and addition levels were significant (P < 0.05). The addition of CaO independent of the level used was not effective in reducing dry matter (DM) losses during ensilage. The total losses of DM presented a significant increase with the levels of addition of CaO, varying from 91 to 177% in relation to the control silage. The addition of urea to all levels had a satisfactory effect on the total loss of DM, ranging from 38 to 69% improvement in the reduction in relation to the control silage. The additive CaO was not efficient in reducing the fermentation losses and preserving the silage. However, urea was efficient in the recovery of DM in the ensilage process.

The objective of this work was to evaluate the chemical composition and rumen disappearance rate of dry matter of corn silages with inoculants combining L. buchneri strain LN40177 in different strata of the silo. The experimental design was a 3x2 randomized complete block design, with three treatments: Control: corn silage without inoculant; 11CFT: corn silage with inoculant which combines L. buchneri strain LN40177 (1.1 x 1011 CFU g-1) with L. casei (1.1 x 1011 CFU g-1); and 11C33: corn silage with inoculant which combines L. buchneri strain LN40177 (1.1 x 1011 CFU g-1) with L. plantarum (1.1 x 1011 CFU g-1) and Enterococcus faecium (1 x 1010 CFU g-1), associated with two strata of the silo (lower and upper). The silage inoculated with 11C33 presented higher contents of crude protein and NDF and lower hemicellulose content in relation to the control treatment and 11CFT. The use of both inoculants resulted in silages with higher concentrations of soluble nutrients. Lower stratum silage had a higher rumen disappearance rate of dry matter compared to the upper stratum. In general, the combinations of L. buchneri promoted nutritional improvements in corn silage, but in presence of L. casei, there were more outstanding improvements.

Due to the seasonal cycle of forage, the use of silage to feed animals provides nutrients throughout the year. However, its quality can be improved with the inclusion of additives and other products. Glycerol is a rich source of energy and present a high efficiency of utilization by animals. The purpose of this work was to evaluate the effect of glycerol inclusion on the chemical and fermentation characteristics of corn and sunflower silages. Two silage sources (maize and sunflower) were used and four levels of glycerol inclusion (0, 15, 30 and 45%) based on dry matter were carried out. The experimental design was completely randomized in a 2 x 4 factorial arrangement with five replications. The pH values and chemical composition of corn and sunflower silages were determined. In both silages there was increment of dry matter, non-fiber carbohydrates and total digestible nutrients (TDN) added to a reduction of crude protein, neutral detergent fiber and acid detergent fiber due to the glycerol inclusion. The corn silage required 45% glycerol to achieve the TDN level of the sunflower silage. The glycerol addition contributed to the increase in the nutritional value, offsetting loss of quality in the ensiling process.

It was evaluated intake, total apparent digestibility, performance and feeding behavior of bovine fed diets constituted of corn silage, crushed sugar cane given fresh or crushed and given 72 hours after storage, ensilaged sugar cane with or without 1% of calcium oxide and concentrate at the proportion of 1% of the body weight. It was used 35 bovines, distributed in a random block design, with 5 treatments and 6 repetitions. The animals were housed in collective stalls with troughs individualized by electronic gates. The animals fed diet with corn silage presented greater intake of all nutrients and greater total digestibility of dry matter, organic matter, neutral detergent fiber and total digestible nutrients, as well as greater weight gain and subcutaneous fat thickness. Animals fed diet with fresh sugar cane presented greater nutrient intake as well as better dry matter digestibility, ether extract and TDN content and a superior performance in relation to animals fed ensilaged sugar cane diets. Animals fed silage of sugar cane with calcium oxide presented greater digestibility of organic matter, NFC and content of TDN but they did not differ on performance in relation to the use of silage of sugar cane without calcium oxide. Intake and performance of animals did not change with or without storage of sugar cane. It was concluded that animals fed diets with corn silage present performances superior to the ones which are fed sugar cane based diets, and animals fed fresh sugar diet are superior to the animals fed diets with sugar cane silage.

The objective of the present study was to perform a meta-analysis that compared the chemical composition of corn silage produced for different experimental purposes, i.e., by research groups that studied corn silage (SCS) or by research groups that only used corn silage (UCS) as a form of roughage. We analyzed 203 papers that were published between January 1994 and December 2014 and contained a total of 647 treatments and the analysis of 1701 silos. We found a significant difference (P < 0.0001) in the dry matter (DM) content of SCS silage (33.00%) and that of UCS silage (30.64%). The DM contents of neutral detergent fiber for the SCS and UCS silage were high (54.72 and 55.14% DM, respectively) but were not significantly different from one another (P = 0.5936), and the acid detergent fiber content of the UCS silage (31.04% DM) was higher than that of the SCS silage (29.65%, P = 0.0214), which indicated that the UCS silage was less digestible than the SCS silage. This was also corroborated (P = 0.0064) by the mean content of total digestible nutrients (64.18% DM) in the UCS silage, which likely results from the lower level of care taken when using standard silage production methods, compared to that taken by SCS researchers. Therefore, we concluded that the corn silage produced by research groups in Brazil are not analyzed in full and that, as a result, there is a paucity of important information, such as the content of organic acids. In addition, we also found that corn silage produced in Brazil contains a high level of neutral detergent fiber.

The objective of this study was to evaluate the efficiency of different types of sealing on the physical losses of dry matter, chemical and fermentation characteristics and in situ digestibility of the dry matter of corn silage stored in the feed out face (ramp) of trench silos. The experimental design used randomized blocks, composed of three treatments, namely: T1 - corn silage preserved with double-sided polyethylene of 110 μm thickness (conventional seal); T2 - corn silage preserved with double-sided polyethylene of 200 μm thickness (double-sided); and T3 - corn silage preserved with oxygen-impermeable film composed of double-sided polyethylene of 80 μm thickness on a translucent vacuum polyamide film of 20 μm thickness (double sealing), with four repetitions each. The use of double-sided polyethylene with 200 μm thickness (double-sided) and oxygen impermeable film composed of double-sided polyethylene and polyamide (double sealing), were effective in preserving the chemical composition, fermentation profile, raw protein composition and fiber quality, in addition, the use of these polymers resulted in greater ruminal digestibility of dry matter and reduced the pH, temperature, temperature gradient and physical losses of corn silage from the feed out face (ramp) of trench silos compared to the conventional sealing.

This study aimed to evaluate the fermentation characteristics, losses and the chemical composition of two pearl millet genotypes silages submitted to nitrogen fertilization. The experimental design was a completely randomized blocks in a split plot scheme 2x5 (two nitrogen genotypes doses x five doses of nitrogen), with four replicates. Nitrogen doses were 0, 20, 40, 60, 80kg ha-1 and the pearl millet genotypes were the variety ADR300 and the hybrid ADR7010. The hybrid ADR 7010 showed average lactic acid content higher than the variety ADR 300, at all doses of N, recording values ranging from 4.09 to 10.46dag kg-1. There was an interaction between nitrogren doses and genotypes for the neutral detergent fiber, which ranged from 51.81 to 63.63dag kg-1 of dry matter. Dry matter recovery decreased linearly with increasing nitrogen doses only for hybrid ADR7010, the same did not happen for the ADR300. The nitrogen fertilization does not favor the fermentation characteristics and increases DM losses of the hybrid ADR7010.

Twenty lactating cows were used over two growing seasons to compare three complete feeds containing corn silage, alfalfa grass silage or ground hay, with long hay as the control. The roughage to concentrate ratio was 6:4 in experiment 1, and 4:6 in experiment 2. There were no significant (P < 0.05) differences m dry matter and total digestible nutrient (TDN) intake among roughage sources except for corn silage in experiment 1. The molar percentage of acetic, butyric, valeric, isobutyric and isovaleric and the molar proportion of acetic to propionic were not affected (P < 0.05) by different sources of roughage. In experiment 1, TDN, dry matter, crude protein and nitrogen-free extract (NFE) digestibility was lower (P < 0.05) for the corn silage diet. However, in experiment 2 there were no significant differences (P < 0.05) in TDN, dry matter, crude protein and NFE digestibility among the experimental treatments. Blood glucose and urea concentrations were not affected by roughage sources. The mean daily (experiment 1) milk yields of cows fed long and ground hay mixtures were greater (P < 0.05) than those of cows fed the alfalfa grass silage mixture; however, the mean daily fat-corrected milk (FCM) yield was not affected (P < 0.05) by the source of roughage (experiment 1). The mean daily milk yield and FCM yield were not affected significantly (P < 0.05) by roughage source (experiment 2). The percentage of milk fat, and solids-not-fat, were not influenced (P < 0.05) by roughage source (experiments 1 and 2). Roughage source appeared to have little effect on molar ratios of fatty acids found in the milk fat.

Agroindustrial co-products are a viable alternative for use in animal nutrition. Tests were conducted using eight different types of co-products and feed to evaluate the chemical composition, in vitro digestibility of dry matter, crude protein and neutral detergent fiber, and gas production by them. The co-products tested were: coffee hulls; pelleted citrus pulp; grape residue; soybean hulls; cottonseed; cassava foliage; and foods usually supplied to ruminants: corn silage and ground corn concentrate. Data of in vitro digestibility of dry matter, crude protein and neutral detergent fiber were tested by analysis of variance using the least square method; the results of gas production were interpreted by a non-linear regression by the Gauss-Newton method; and the effects of treatments were evaluated by the Tukey’s test. The coefficients of in vitro digestibility of dry matter, crude protein and neutral detergent fiber of co-products were different. Gas production was also different between co-products and feeds evaluated for the volume of gas produced from the fast and slow degradation fractions, degradation rate, bacterial colonization time, and the total volume of gas produced. The evaluated co-products exhibited greater in vitro dry matter digestibility compared to corn silage, except for cottonseed, grape residue, and cassava foliage. Co-products showed higher values of in vitro crude protein digestibility compared to corn silage, and a reduced in vitro digestibility of neutral detergent fiber, except for pelleted citrus pulp and soybean hulls. Corn silage produced larger volume of gas from the fast degradation fraction compared to the co-products and corn concentrate. Co-products analyzed had appropriate nutritional characteristics according to the techniques applied and can be included in ruminant diets.

The present study aimed to evaluate the chemical composition of carbohydrates and nitrogenous fractions of late-crop corn silages with different specific masses (SM; 90, 134, 172, and 214 kg dry matter m-3). The silage was held in 20-L mini-silos, and the experimental design was completely randomized, with four replications (mini-silos) per treatment. Fractionation was performed according to The Cornell Net Carbohydrate and Protein System (CNCPSv5.0). The SM of the silage significantly affected the contents of ether extract ( ? = 1.718 + 0.0041?SM; P = 0.009; R2 = 39.2), soluble sugars ( ? = 0.9502 - 0.003445?SM; P < 0.001; R2 = 59.9), and soluble fiber ( ? = -0.4731 + 0.01158?SM; P = 0.025; R2 = 31.2). In addition, SM also affected carbohydrate fraction B1 in a linear manner ( ? = 14.88 + 0.2566?SM; P = 0.043; R2 = 38.4), whereas the remaining fractions were unaffected. Furthermore, no change was observed in total N ( ? = 2.003 - 0.01065?SM + 0.000036?SM2; P = 0.041; R2 = 38.8), non-protein N ( ? = 1.436 - 0.01103?SM + 0.000036?SM2; P = 0.060; R2 = 35.1), soluble N ( ? = 1.715 - 0.01450?SM + 0.00005?SM2; P = 0.024; R2 = 43.8), or neutral detergent insoluble N ( ? = 0.4979 - 0.001057?SM; P < 0.001; R2 = 70.6). The results also contributed to the differences in fractions A ( ? = 66.47- 0.5291?SM + 0.00174?SM2; P = 0.095; R2 = 30.4), B2 ( ? = 6.78 + 0.05857?SM; P = 0.076; R2 = 20.8), and B3 (? = 19.03 - 0.05565?SM; P = 0.018, R2 = 34,1) of the Cornell model. In the present study, differences in the compression (i.e., SM) of corn silages caused changes in the contents of soluble sugar and nitrogenous constituents; however, SM alone did not explain the entire preservation of the ensiled material.
