| The objective of this study was to evaluate intake, in vitro and apparent digestibility and ruminal parameters of Holstein cows that were confined and fed corn silage and concentrate containing: ground sunflower seeds (GS); ground sunflower seeds treated with 5% lignosulfonate (GSL); pelleted sunflower seeds (PS); or ground and pelleted sunflower seeds treated with lignosulfonate (PSL). Four lactating cows with 130±28 days of lactation and body weights of 569±63 kg were used. These animals were distributed in a Latin square design with four diets and four periods of 21 days each. There were no differences in the intakes (% body weight) of dry matter (DM), organic matter (OM), mineral matter (MM), crude protein (CP), neutral detergent fiber (NDF) or acid... |

| This trial was conducted aiming to evaluate the effects of Brachiaria brizantha vegetative seed harvest residues hay treated with anhydrous ammonia (NH3) or urea, and protein sources on the steers performance, and carcass quality. Twenty-four male beef cattle were (12 F1 Nellore X Aberdeen Angus and 12 F1 Nellore X Red Angus), distributed in four treatments, with six replications. Animal crossbreed type and initial body weight were considered blocks. The diets were: Untreated hay supplemented with non-protein nitrogen (UHNPN); untreated hay supplemented with cottonseed meal (UHCM), hay treated with 5% urea (HTU), hay treated with 3% anhydrous ammonia (HTA) of DM%. Diets were formulated to be isoproteic and isoenergetic. The initial body weight (kg), daily... |

| ABSTRACT The purpose of this study was to evaluate the effect of the chemical treatment with fungicide, insecticide, micronutrient and polymer on physiological and sanitary quality of soybean seeds during storage. The treatments were arranged in a 3 x 5 x 5 factorial scheme (cultivars x seeds treatment x storage period), in completely randomized design with four replicates. Three cultivars were used: NA 4823RG, BMX TurboRR and Fundacep 62RR. The treatments were: T1: no chemical treatment, T2: fungicide, insecticide and micronutrient; T3: fungicide, insecticide, micronutrient and polymer, T4: fungicide; T5: insecticide. After the chemical treatment, the seeds were stored under environmental conditions from May to December 2012, and seed quality was... |

| ABSTRACT: In this study, the aim was to determine the influence of potassium nitrate, using different concentrations and immersion times on the dormancy of the seeds of Brachiaria humidicola cv. ‘BRS Tupi’. Four experiments were performed adopting a factorial scheme (5x3+1) in different seed lots, for different post-harvest storage durations, during which the seeds were immersed in potassium nitrate solutions of different specific concentrations (0, 0.1, 0.3, 0.5 and 1% KNO3), for three exposure periods (12, 24 and 48h), plus one control (untreated), in a completely randomized design. The characteristics assessed included the imbibition curve, germination, first count and germination rate, as well as viability confirmed by using tetrazolium test. From the... |

| Four multiparous Holstein cows averaging 548 kg of body weight and 74 d in lactation were used in a Latin square design with four 21-d experimental periods to determine effects of feeding extruded versus non-extruded canola seed, with or without 50 g/kg lignosulfonate on rumen fermentation, nutrient flow to the omasum, and degradability of dry matter (DM) and N of each diet. The DM effective degradability increased with extrusion and lignosulfonate treatment had no effect. The effective degradability of N was similar between diets. Lignosulfonate treatment of extruded versus non-extruded canola seeds decreased ruminal and total tract apparent digestibility of organic matter. The lowest apparent ruminal and highest intestinal digestibilities of protein,... |

| The objective of this work was to evaluate, in bovines, the intake and apparent digestibility of nutrients, ingestive behaviour and content of total digestible nutrients (TDN) of diets based on sugar cane treated with calcium hydroxide. It was used four cows with average body weight of 412.06 kg ± 37.3 kg. The study included inclusion of calcium hydroxide at the doses 0, 8, 16 and 24 g/kg of sugar cane in natural matter basis fed in diets with 65% of roughage and 35% on concentrate, based on dry matter (DM). It was used a 4 × 4 Latin square experimental design with four treatments and four periods. Calcium hydroxide doses affected nutrient intake: DM intake was 7.88 kg/day at the dose of 14.99 g of calcium hydroxide, organic matter (OM) intake was 6.75... |

| Swine manure agricultural use is a common practice in Brazil. Their physic-chemical characteristics favor its use as biofertilizer, but the presence of pathogens may become a risk to human health. This research presents a qualitative study of the main alternatives of pig manure disinfection, analyzing efficiency, advantages and limitations of each procedure. The disinfection studies reported in literature are based on the following treatments: alkaline, thermal, biological, chemical, and physical. The greater efficiencies are in thermal treatment (> 4 log: 60 °C), chemical treatment (3 to 4 log: 30mg Cl- L-1; 3 to 4 log: 40 mg O3 L-1) and physical treatment (3 a 4 log: 220 mJ UV radiation cm-2). The biological treatment (anaerobiosis) also promotes the... |
