| Os produtos de origem animal destinados ao consumo humano representam um papel importante na epidemiologia das salmoneloses humanas. Mesmo com tantos avanços tecnológicos e a modernização das indústrias, a carne de frango é passível a contaminação bacteriana, especialmente por microorganismos do gênero Salmonella, que podem estar alojados no trato intestinal das aves. A prevalência da salmonelose é diferenciada nas diversas regiões do país e sua epidemiologia e controle são bastante complexas. A decorrência disso é a condição de criação dos animais, padrões de higiene e biossegurança, nível de contaminação do alimento, fatores sócio-ambientais e fatores ambientais. Assim o seu controle torna-se um grande desafio para o setor avícola, pois há uma... |

| The design of additives for animal feed or growth promoter is associated with the incorrect notion of elements harmful to food security. Many additives can have a beneficial effect on health of the animal without interfering with their nutrition, being called nutraceuticals. Many of these additives play an important role in the production of animal protein, especially in pig and poultry industry. This review will be studying two nutraceuticals, also called evaluated micro, antimicrobials and prebiotics in animal diets. |

| The swine nutrition in recent years has been the focus of several experimental studies, especially in relation to protein and amino acid nutrition. In this context, arginine is one of the amino acid in increasing research, which metabolism is dynamic, participating in several metabolic pathways and generating numerous compounds. The arginine synthesis occurs primarily in the intestinal-renal axis, where lining cells from the small intestine produce citrulline and proximal tubule cells from kidney extract citrulline from the bloodstream, converting it into arginine, returning it to circulation. Arginine is chemically named 2-Amino-5-Guanidopentanoic Acid, and it is a conditionally nonessential amino acid for pigs, considering that is required primarily... |

| This study aimed to evaluate different digestible lysine levels in diets for broilers chickens from different commercial strains, from 49 to 56 days of age, on performance and carcass characteristics. A total of 432 male broilers from 49 days old were used, with an average weight of 3560±250 g. It was used a completely randomized design in a factorial arrangement 3x4, and the birds, from three strains (Cobb 500, Hubbard Flex and Ross 308) were divided into four levels of digestible lysine (0.800, 0.950, 1.100 and 1.250%), with four replicates of 12 birds each. It was evaluated the weight gain, feed intake, feed conversion ratio, carcass yield, breast yield, breast meat yield and the yield of the thigh and drumstick. There was no interaction between lysine... |

| The aim of this study was to determine the proper drying thickness and time in the sun, on cement floor, brewery waste. For the experiment was used brewery residue obtained in industry located in the municipality of Toledo - PR, which had DM content of 20.60%. The waste was distributed over the concrete surface with the aid of 26 frames with 2, 4, 6 and 8 cm thicknesses, corresponding to treatments, with six replications. The waste was exposed to sunlight for three days (9 o'clock on day 11 hours on the second day and 11 hours on the third day), and trashed every two hours of exposure to sun and covered during the night, to avoid deposition dew. Significant variation was observed for dry matter (DM), organic matter (OM), mineral matter (MM), crude protein... |

| The objective of this study was to evaluate the carcass yield of broilers fed diets containing different levels of energy and digestible lysine in the growth phase from 21 to 42 days old. We used 768 male Cobb broilers, 21 days old, divided in a completely randomized design containing 16 treatments (four lysine levels x four energy levels), three replicates of 16 birds each. The lysine levels were 0.9, 1.0, 1.1 and 1.2%, and the energy levels were 2800, 2950, 3100 and 3250 kcal kg-1. The different levels of digestible lysine increased linearly (P <0.05) carcass yield of broilers at 42 days, while the metabolizable energy level had no effect (P> 0.05) on this variable. There was no interaction between levels studied on the yield of breast, thigh and... |

| Introdução A produção de frangos de corte representa grande importância para a economia brasileira, sendo um potente gerador de emprego e renda. Nos últimos anos, tem apresentado avanços no aspecto produtivo, parte destes associados ao melhoramento genético e ao avanço do conhecimento nas áreas de manejo, de alimentação e de nutrição (ALBINO et al., 2007). Desta maneira, a nutrição desempenha importante papel, que abrange desde a formulação de dietas que visam atender às exigências nutricionais, como busca pelo incremento no aproveitamento dos nutrientes presentes nos alimentos, em geral a base de milho e soja. Assim, o dinamismo da nutrição animal vem buscando novas estratégias para melhorar a digestibilidade dos alimentos e proporcionar condições... |
