| The elephant grass presents problems during the fermentation of the ensiled material, being necessary use of additives. This study aimed to evaluate the population of yeast and filamentous fungi, enterobacterias, contents of acetic and butyric acids and ethanol production, in elephant grass silages added with different levels of macaúba cake at opening times. This was a 3 x 6 factorial completely randomized experimental design, with three inclusion levels of the macaúba cake (0, 10 and 20%) and six opening times (1, 5, 10, 20, 40 and 60 days after ensiling), with four replications. For all the studied variables, there was a difference in the interaction among levels and times, and an increasing linear behavior only for the contents of acetic acid, for the... |

| The present experiments were conducted to assess the effects of barley, Lactobacillus bacteria and lactic acid bacteria (LAB) and enzyme mixture supplementations on chemical composition and some quality parameters of naturally frosted maize silage. The treatments were as follows; T1: Control (no supplementation, C); T2: barley 20 g kg-1, B20; T3: barley 40 g kg-1, B40; T4: 1.5 g ton-1, a mixture of LAB; and T5: 2 g ton1, a mixture LAB+enzyme, LEN. Barley supplementation to frosted maize increased dry matter (DM) (p < 0.01). The pH value was higher in LAB group (p < 0.01). Treatments supplemented LAB and LEN significantly reduced crude protein contents (p < 0.001). Lactic acid contents decreased in all treatments as compared to control group and... |

| ABSTRACT Preserving forage plants adapted to a semi-arid climate as silage may minimize the animal feed deficit during drought. The objective of this study was to evaluate the effects of different quantities of grape pomace added to Calotropis procera silage on its fermentation, in vitro digestibility, total digestible nutrients and microbiology. A completely randomized experimental design was used with four treatments (0, 10, 20 and 40% fresh matter) and four replicates. The silos were opened after 90 days of ensilage, and the soluble carbohydrate, ethanol, organic acid and ammoniacal nitrogen concentrations; pH; fermentation loss; dry matter (DM) recovery; DM density, and microbial populations were determined. The pH (3.96-3.87) was adequate for ensiling... |

| Phenolic compounds and anthocyanins content in grape juices varies in the cultivar, ripening and climate characteristics. The objective of this work was to characterize and evaluate antioxidant activity of grape juices produced in southwestern Minas Gerais. Grapes were harvested, sanitized and the juices from cultivars 'Bordô', 'Isabel Precoce', 'BRS Violeta' and 'BRS Rúbea' were produced in artisanal equipment by steam extraction and stored for 120 days. The following analyzes were performed during storage: color (L *), pH, soluble solids, titratable acidity, anthocyanins, antioxidant activity (DPPH and β-caroteno/linoleic acid), total phenolics, vitamin C and organic acids. Among the cultivars evaluated, the consumption of grape juice from cultivar 'BRS... |

| Jaboticaba is a Brazilian fruit, native to the Atlantic forest, which belongs to the Myrtaceae family. In this work we describe the effect of the thinning of "flower", "fruit" and "flower & fruit" compared to non-thinned fruit (control) and of edible coatings with respect on nutritional composition, overall acceptability and shelf-life of jaboticaba ‘Sabara’, grown in an irrigated commercial orchard. "Flower and fruit" thinning allows fruit with higher quality as diameter, volume and mass. Non-thinned fruit shows higher yield, however fruit have lower quality. As a result of the improving quality at harvest, the shelf life was twice (~8 days) for thinned fruit. The lack of change in concentration of soluble sugar and absence of formation of... |

| Abstract Guava is very delicate and alluring fruit which is being ignored since very long time despite of highly nutritious fruit and rich source of Vitamin C. It contains Vitamin C 2-3 times more than orange. Naturally the guava fruit is enriched with vitamin C and polyphenoles. Guavas fruits after harvesting were dunked in solutions of CaCl2 (1, 2 and 3%) at room temperature for 5 minutes and stored for 24 days in 5% CO2 level at temperature of 10±1°C, while the humidity level of storage chamber were 80%. The stored fruits were analyzed at 6 days of interval for sugars (glucose, fructose and sucrose g/100g) total phenolic contents (mgGAE/100g), antioxidant activity (µmolTE/g), and organic acids (citric, tartaric, ascorbic, and malic acids mg/100 g). The... |

| ABSTRACT: The use of nitrogen fertilizers in corn crops for silage can improve both production and, theoretically, nutritional quality, especially carbohydrate and protein fractions, thereby optimizing animal production. Thus, the aim of this study was to evaluate the effect of increasing levels of nitrogen fertilization in carbohydrate and protein fractionation on the resulting corn silage (Zea mays L.). Nitrogen fertilization was carried out in the urea form (45-00-00) in V5 stage, at the following doses: T1: 0kg N ha-1; T2: 45kg N ha-1; T3: 90kg N ha-1; and T4: 135kg N ha-1. Crops were harvested at R4 stage and submitted to ensiling in experimental PVC silos. The chemical composition of the resulting silage was evaluated after silo opening. There was no... |

| ABSTRACT: This experiment was conducted to evaluate the effect of growth promoter additives an alternative to antibiotics on performance, intestinal morphology and on microbiota of 21-to-35-day-old piglets. A total of 160 commercial crossbred piglets (males and females) with initial weight of 6.10±0.709kg were allotted in a completely randomized design with five treatments: Basal diet - Negative Control (NC); Basal diet + antibiotic (PC); Basal diet + mannanoligosaccharides (MOS); Basal diet + organic acids (OA), Basal diet + mannanoligosacharides + organic acids (MOS+OA), eight replicates and four piglets per experimental unit. The inclusion of additives in the diets had no effect (P>0.05) on the final average weight of piglets. Similarly, no effects... |

| La inocuidad es un requisito importante de aceptación en el jitomate (Lycopersicum esculentum L.), para permitirle abrir nuevos mercados. En los que además, el fruto debe cumplir con ciertos estándares de calidad relacionados con sus propiedades físicas y químicas. El presente trabajo tuvo como objetivo determinar las propiedades físicas y químicas del fruto de jitomate almacenado a diferentes temperaturas en presencia de Escherichia coli (ECET). Se utilizaron frutos de jitomate variedad Charleston, cultivados en invernadero de hidroponía en el Municipio de Aquixtla, Puebla. Los frutos se sometieron a dos temperaturas de almacenamiento (7 y 22°C), inoculados con 7 log10UFC/mL de E. coli (ECET). Se evaluaron algunas propiedades físico-químicas como color,... |
