| This study evaluated a phytogenic feed additive for broiler chickens. A total of 1,632 broiler chicks were distributed into four treatments: negative control (without growth promoter); positive control (avilamycine, 10ppm + colistin, 15ppm); and two alternative treatments with 150ppm of phytogenic additive, one with a reduced Ca and P levels diet (PA-R1) and the other with lower energy, and amino acids, besides Ca and P (PA-R2). The trial was conducted with 12 replicates, each consisted of a pen with 34 birds. The alternative diets showed body weight intermediate to the two controls at 42 days, with no significant (P>0.05) treatment effect on feed conversion ratio. No treatment differences (P>0.05) on carcass yield and composition was observed. There... |

| The chemical composition of 10 selected plant essential oils obtained by steam distillation was determined by GC and GC/MS. The antimicrobial activity of the essential oils was screened against 12 important food-related bacterial strains by agar disc-diffusion assay. MIC and MBC were determined for the essential oils that presented the highest activity in the agar disc-diffusion test. The most active essential oils against the tested bacteria were, in descending order, lemongrass (Cymbopogon flexuosus), basil (Ocimum basilicum), oregano (Origanum vulgare), cinnamon leaf (Cinnamomum zeylanicum), and laurel (Laurus nobilis). Except for S. Typhimurium, the tested bateria were inhibited at MIC values lower or equal to 0.62mg mL-1 by lemongrass (Cymbopogon... |

| O manejo pré-abate dos suínos, quando realizado de maneira inadequada, pode proporcionar perdas qualitativas e quantitativas. O objetivo deste trabalho foi avaliar o efeito do período de descanso dos suínos no frigorífico (PDF) (3, 5, 7 e 9 horas) e da posição do box na carroceria do caminhão (PBO) sobre a perda de peso corporal (PPC), o peso do estômago cheio (PEC) e vazio (PEV), o peso do conteúdo estomacal (PCE) e o escore de lesão na mucosa esofágica-gástrica (ELG). Foram utilizadas 192 fêmeas, com peso vivo médio de 130,0±9,9kg. Para a análise estatística, considerou-se no modelo os efeitos de bloco (BL), relativo à estação do ano e à granja avaliada o PDF, PBO e a interação entre PDF x BL. Não houve efeito significativo do PDF nas variáveis... |
