| Foi realizado um experimento objetivando avaliar os efeitos de promotores de crescimento sobre o desempenho e a temperatura corporal de frangos de corte, no período de 1 a 42 dias de idade. Os tratamentos consistiram de uma ração basal não suplementada (Controle), ou suplementada com 200 mg de Cu/kg de sulfato cúprico pentahidratado (Sulfato), 75 mg de Cu/kg de citrato cúprico anidro (Citrato), 20 mg/kg de virginiamicina (VM), ou a associação Citrato + VM, em um experimento em blocos casualizados com seis repetições de 40 aves, criadas sobre cama reutilizada. Não se observou efeito de tratamentos na fase inicial. Na fase final os tratamentos não afetaram o consumo de ração e o ganho de peso, enquanto a conversão alimentar foi melhor para o VM comparado ao... |

| There are some evidences described in the literature showing reduced energy metabolizability of ingredients for newly hatched chicks. Hence, a metabolism trial was carried out with the objective of determining the metabolizable energy of corn grain, soybean meal and micronized full fat soybean for newly hatched chicks. The method of total excreta collection was used in an experiment with 192 male chicks from one to seven days, distributed in a completely randomized design with four treatments and four replicates of twelve birds. Excreta were collected from four to seven days of age. The treatments included a reference diet, two test-diets consisting of 60% of the reference diet and 40% of the test ingredients: corn grain (CG) and soybean meal (SM), and one... |

| ABSTRACT In order to evaluate the antioxidant effects of barbatimão (BAR) or pacari (PAC) on chicken meat oxidative stability and quality, seven dietary treatments containing in three different BAR and PAC concentrations (200, 400 and 600ppm) plus a negative control (CONT) were fed to 350 broilers from 1 to 41 days of age. Ten birds per treatment were slaughtered to collect breast and thigh meat to evaluate pH, color (L*, a*, b*), cooking weight loss (CWL), and shear force (SF) 24 hours postmortem, and TBARS levels in precooked meatballs stored chilled for 8days. The dietary supplementation with BAR and PAC extracts did not affect pH and color, but reduced (p<0.05) SF in breast meat compared with CONT suggesting improved tenderness. PAC200 increased... |

| ABSTRACT The aim of this study was to evaluate the effect of digestible threonine supplementation in the starter diet on the performance, intestinal parameters, and nutrient metabolism of broilers derived from breeders of different ages. In total, 480 one-day-old Cobb chicks, derived from 38-or 49-week-oldbreeders, were housed in experimental battery cages until 21 days of age and fed four different threonine levels (800, 900, 1,000, or 1,100 mg/kg) in the starter feed. A completely randomized experimental design in a 2x4 factorial arrangement (breeder age x threonine levels) was applied, totaling eight treatments with five replicates of 12 birds each. Broilers from older breeders fed 800 mg digestible threonine/kg of diet presented higher weight gain,... |

| Este estudo foi desenvolvido com a finalidade monitorar a qualidade da farinha de carne e ossos (FCO), durante o armazenamento prolongado (10 semanas), e avaliar os efeitos da adição do BHT (500mg/kg) a esta farinha. Um lote fresco de FCO (41,12% PB e 9,14% EE) foi dividido em seis partes iguais, sendo uma não tratada (CONTROLE) e as demais tratadas com BHT em diferentes tempos de armazenamento (nos dias 0, 7, 14, 21 e 28: BHT/0, BHT/7, BHT/14, BHT/21 e BHT/28, respectivamente). As FCO foram armazenadas em ambiente diariamente monitorado e sua qualidade foi avaliada por amostragens semanais, com determinação do índice de peróxidos, cujo nível máximo obtido foi de aproximadamente 80meq/kg (CONTROLE). A partir da 4ª semana de armazenamento, foi conduzido um... |

| ABSTRACT An experiment was conducted to evaluate the addition of the oil resins ofsucupira (Pterodon emarginatus Vog.) and copaiba (Copaifera langsdorffii) to broiler diets on chicken meat composition, quality, and lipid peroxidation. 350 one-d-old broiler chicks were submitted to seven treatments, consisting of the diets supplemented with copaiba (COP) or sucupira (SUC) resin oils at three different concentrations (500, 900, and 1300 ppm) plus a negative control diet (CONT). At 37 days of age, 10 birds per treatment were selected according to the average weight of the experimental unit and slaughtered to collect breast and thigh meat, which was stored at 4°C for 24 hours to evaluate pH, color (L*, a*, b*), cooking weight loss (CWL), and shear force (SF).... |

| Feed is responsible for about 70% of broilers production costs, leading to an increasing number of studies on alternative dietary products that benefit bird performance and lower production costs. Since the 1950s, antimicrobial additives are the most frequently used performance enhancers in animal production and their positive results are observed even in high-challenge conditions. Since the 1990s, due to the ban of the use of some antibiotics as growth promoters and the growing trend of the public to consume natural products, plant extracts have been researched as alternatives to antibiotic growth promoters. The first study that evaluated the antibacterial activities of plant extracts was carried out in 1881; however, they started to be used as flavor... |

| O experimento avaliou o desempenho de frangos de corte suplementados em 4% na ração com três fontes de gordura: óleo ácido de soja (OAS4) e sebo bovino (SEBO4), óleo de soja (SOJA4) e misturas de 2% entre estas: (OAS2/SEBO2), (OAS2/SOJA2) e (SOJA2/SEBO2). Foram utilizados blocos casualizados, com 6 tratamentos, 6 repetições e 40 aves por parcela. Foram avaliadas as variáveis: consumo de ração (CR), ganho de peso (GP), peso vivo (PV), conversão alimentar (CA), fator de produção (FP) e viabilidade (VB), aos 42 dias de idade. Para análise, foram utilizados contrastes não ortogonais: 1- SOJA4 X (OAS4 + SEBO4 + OAS2/SEBO2); 2- SOJA4 X (OAS2/SOJA2 + SOJA2/SEBO2); 3- OAS2/SOJA2 X SOJA2/SEBO2; 4- OAS4 X OAS2/SOJA2; 5- OAS4 X OAS2/SEBO2. No contraste 1, observou-se... |

| This study was conducted to determine the effect of microbial or antimicrobial additives on the performance and organ morphology of broilers raised in batteries or in floor pens. The effect of microbial additives on the presence of oocysts in the litter was also studied. Experiments 1 and 2 consisted of four treatments (non-supplemented control diet or diet supplemented with avilamycin, bacitracin methylene disalicylate or enramycin) and six repetitions in a randomized block design. In Experiment 1, 288 day-old chicks were housed in heated batteries in a environmentally controlled room, 12 chicks per cage; in Experiment 2, 1,200 day-old chicks were housed in a curtain-sided experimental house, with concrete floor and rice hulls as litter material, 50... |
