| This work was realized to evaluate the effect of natural additives as propolis or essential oils addition on animal performance, feed intake, apparent digestibility and carcass characteristics of bulls finished in feedlot. Thirty bulls (½ Aberdeen Angus vs. ½ Nellore) were randomly assigned in one of three diets (control – CON, propolis – PRO and essential oils – OIL) and kept in feedlot (individual pen) during 55 days. CON diet consists of 45% corn silage, 40% concentrate (cracked corn, soybean meal, limestone and mineral salt) and 15% glycerine. The PRO group received same diet that control plus 3 grams to animal day-1 of propolis dry added to the concentrate. The OIL oils group received same diet that control and 3 grams to animal day-1 of essential... |

| Abstract Isotope-ratio mass spectrometry (IRMS) is a potential tool that provides time-integrated estimate of assimilated and not just ingested nutrients. This feature turned possible its application to evaluate the effects of dietary nucleotides and glutamate on carbon turnover (δ13C) in the brain of weanling piglets. Eighty-seven piglets weaned at 21-day-old were used, being three piglets slaughtered at day-0 (prior to diet-switch) and, the remaining 84 randomly assigned in a complete block design with a 2 x 2 factorial arrangement of treatments (two nucleotide levels: 0% and 0.1% and, two glutamate levels: 0% and 1%). On trial days 3, 6, 9, 14, 21, 35 and 49, three piglets per treatment were also slaughtered. The samples were analyzed by IRMS and... |

| ABSTRACT Organic acids are used as feed additives to promote growth of weaned piglets since they prevent the occurrence of diarrhea. Thus, performance and digestibility assays were conducted and economic viability of diets was evaluated. In the performance assays, 64 hybrid piglets weaned with a mean weight of 5.87±0.31kg were divided in a randomized block design consisting of 4 treatments, 8 repetitions and 2 piglets per experimental unit (1 castrated male and 1 female). In the digestibility assay, 24 castrated male hybrid piglets with a mean weight of 8.21±0.79kg were individually assigned to 4 treatments and 6 repetitions. The treatments in the two assays were as follows: control, basal diet without addition of an acidifier; blend: inclusion of 0.5% of... |

| ABSTRACT Fermentation profile and microbial population were assessed in soybean silages without any additive (control), with inoculant (I), with I + powdered molasses (I+M), and with powdered molasses only (M). Soybean plants were harvested at the R6 stage and ensiled in 2kg-capacity laboratory silos. The additives were added to the natural matter base of silages. The assessed fermentation periods were 1, 3, 7, 14, 28, and 56 days. A 4 × 6 factorial arrangement (4 additives × 6 fermentation periods) in a completely randomized design with 3 replicates was used. Lactic, acetic, and butyric acids concentrations were influenced by additives and periods (P< 0.05). It was observed higher lactic acid values to control silages, on the 56th day. Lower average... |

| ABSTRACT The aim of this paper was to evaluate the effects of including virginiamycin (VM), sodium monensin (MON) or the association (VM+MON) in the energetic mineral supplement, on the intake and performance of beef cattle on pasture. Forty Nellore heifers with 24 months of age and initial body weight (BW) of 251.5±16.6kg, were distributed in four treatments in a randomized block design. Treatments consisted of adding VM, MON or VM+MON to the supplement (CONT). Additive concentrations were defined to reach a dose of 40 to 45mg/100kg BW. The herbage allowance was not a limiting factor for the animals’ intake. Supplement intake was lower than expected, with 33.0, 18.8 and 26.3mg per 100kg BW for VM, MON and VM+MON, respectively. Dry matter intake (DMI,... |

| Abstract Honey must supplementation is necessary for mead production due to the deficiency in nitrogen materials in this feedstock, despite its high fermentative sugar content. The nitrogen limitation can halt or slow fermentation and lead to the production of unpleasant sensorial compounds, such as sulfur derivatives. The yeast JP14, a Saccharomyces cerevisiae isolated from Jataí bee’s pollen, was inoculated in 25 °Brix honey must with – 0 (control); 0,3; 0,7 and 1,0 g∙L-1 – of di-ammonium phosphate (DAP) and ammonium sulfate (AS). The addition of both supplements resulted in increased cell viability in the first 5 days of fermentation at 20 °C, but did not affect the final acidity of the produced meads. Supplementation also leads to increased sugar... |

| ABSTRACT: Cat food formulation should not only meet the animal's nutritional needs, but also take into account food attractiveness. Our aim was to assess the palatability of food coated with sodium pyrophosphate and yeast extract, alone or in combination, and 20 adult cats were used in a two-bowl preference test. The preference for the experimental foods was tested by external application of sodium pyrophosphate (0.3%), yeast extract (0.2%), and a blend (0.5%) containing pyrophosphate and yeast extract in a same basal diet. In the present study, the cats showed preference for the blend (0.5%) containing sodium pyrophosphate and yeast extract. |

| ABSTRACT: This study was conducted to evaluate the effects of additives on the fermentation characteristics, chemical composition and in vitro digestibility of tetraploid black locust (TBL). The TBL leaves silage was either untreated (control) or treated with 1 × 106 cfu/g FM Lactobacillus plantarum (L), 1% glucose (G), 3% molasses (M), a combination of 1% glucose and Lactobacillus plantarum (L+G), or a combination of 3% molasses and Lactobacillus plantarum (L+M). Fermentation quality, chemical composition and nutrient digestibility were then analyzed. Ethanol and acetic acid concentrations were the dominant fermentation products in all silages except L+M silage. The L, G and L+G treatments failed to influence the fermentation. The M treatment increased... |

| Chemical additives are used extensively in the offshore oil industry. For secondary oil recovery, the biopolymer xanthan has been recommended as a viscosifying agent but its use may provoke microbial problems. The effect of adding xanthan to marine sediments on the growth and metabolic activity of sulphate-reducing bacteria (SRB) was studied. In all instances, its addition resulted in an increasing in SRB numbers of up to 250-fold. This was accompanied by a marked increase in the electron transport activity of the sediments when these were incubated under either aerobic or anaerobic conditions. The products formed as a result of the biodegradation of the polymer by indigenous heterotrophic bacteria in these sediments appear to have acted as suitable... |

| Abstract: The objective of this work was to evaluate the effects of dietary glutamine and glutamic acid supplementation on carbon turnover (δ13C) in the muscles of piglets, on animal performance, and on feed economic feasibility. The diets consisted of: control (C), 1% glutamine (G), and 1% glutamic acid (GA). In experiment I, 111 piglets were used to assess carbon turnover in the Masseter, Psoas major, and Abdominal internal oblique muscles in terms of their isotopic composition and 13C substitution over time. In experiment II, 72 piglets were assigned randomly to blocks (eight replicates per treatment and three animals per experimental unit), in order to evaluate animal performance and feed economic feasibility. The GA diet promoted the best 13C... |
