| Objetivou-se com este trabalho avaliar o efeito de aditivos promotores de crescimento (prebiótico, probiótico e simbiótico) em substituição ao antibiótico sobre o desempenho e características de carcaça (cortes nobres, órgãos e gordura abdominal), em dietas para frangos de corte de um a 42 dias de idade. Foram utilizados 384 pintos de um dia de idade alojados sobre cama reutilizada. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro tratamentos e seis repetições, sendo: PRO - suplementação com probiótico (2 kg t-1), ANT – suplementação com antibióticos (flavomicina 10% - 4 ppm e halquinol 60% - 15 ppm), PRE – suplementação com prebiótico (5 kg t-1), SIMB – suplementação com probiótico e prebiótico (2 e 5 kg t-1,... |

| Abstract This study aimed to evaluate the intestinal morphology, performance and financial analysis of the inclusion of additives in the feed during the productive period of 360 Japanese quails distributed in a completely randomized design in a split plot scheme in time with five treatments and eight repetitions of nine birds each. The treatments were: control, antibiotic, prebiotic, probiotic and synbiotic. The variables were: height, width and width/height ratio of the villi, crypt depth and villus/crypt ratio, feed intake, egg production, egg weight average, egg mass, feed conversion per mass and per dozen eggs and viability, internal rate of return, net present value and cost benefit. The additives in the feed increased height and width of the villi,... |

| Endophytes are symptomless fungal or bacterial microorganisms found in almost all living plant species reported so far. They are the plant-associated microbes that form symbiotic association with their host plants by colonizing the internal tissues, which has made them valuable for agriculture as a tool in improving crop performance. Many fungal endophytes produce secondary metabolites such as auxin, gibberellin etc that helps in growth and development of the host plant. Some of these compounds are antibiotics having antifungal, antibacterial and insecticidal properties, which strongly inhibit the growth of other microorganisms, including plant pathogens. This article reviews the endophyte isolated from different plants, mode of endophytic infection and... |

| This work aimed to evaluate the effects of probiotic associated to prebiotic on performance, carcass and cut yields, qualitative traits of meat, development and score of lesions due to coccidiosis in digestive tract of broiler chickens raised in a free-range system during 85 days. One thousand, six hundred and ninety-six day-old male broiler chicks from naked-neck ISA S757-N Label Rouge line were used in a randomized block design with factorial scheme of 4x2 and four repetitions. The effect of four additive (1 - biologic promoter + coccidiosis vaccine; 2 - biologic promoter + anti-coccidiosis; 3 - chemical promoter + coccidiosis vaccine; 4 - chemical promoter + anti-coccidiosis) and two breeding systems from 35th day of age (one with no-access to pasture... |
