| Abstract: The objective of this work was to determine the correlation of the physical attributes of corn and the mycotoxins present in its grains with the severity of tongue lesions in broiler breeder roosters. The occurrence of the aflatoxin, vomitoxin, zearalenone, T-2 toxin, and fumonisin mycotoxins was detected in the corn grains used in the feed formulation for breeder chickens. The percentages of moisture and broken grains were positively correlated (Pearson’s correlation) with the presence of aflatoxin. Milder lesions (grade 1) are positively correlated with aflatoxin and negatively correlated with fumonisin, and the most severe lesions (grade 3) are positively correlated with vomitoxin, fumonisin, and T-2 toxin. |

| This paper has the main goal of analyzing and evaluating the structure and dynamics of the market from the exporting section of Brazilian chicken raising, from 1996 to 2004. Concentration rates were calculated in order to measure the market share which are dominated by the main companies. The dynamics of the sector position (turnover) was also checked. The reached results point that the sector concentration is higt, and great investments are necessary to the performance in the international market; the placement of the companies was changed mainly due to the ones which had lost positions compared to the first year. However, the concentration has decreased, and there is evidence that the market power hasn’t been used by the companies in a sense of reducing... |

| The entrance of poultry products into the trade world requires changes in the configuration of these products, such as programs that ensure their quality and biosafety for the consumers. This article aims at presenting new perception on poultry biosafety programs in broiler breeder farms from an ecological perspective, making these programs more efficient and cost-effective, i.e., more competitive. Using literature review, some convergences were found between ecology concepts and biosafety programs. One of these convergences is understanding the farm as an open ecosystem, integrating through adaptation the natural environment with the exotic environment. This also allows understanding how the production area interacts with the environment as to energy... |

| ABSTRACT The objective of this study was to evaluate the sustainability of a broiler chicken production system, with confinement in Darkhouse sheds, by energetic analysis. Energy flows of a complete production cycle, 56 days, were considered, of which the energy inputs and outputs were computed in direct and indirect forms, by estimating the energy coming from the quantity of feed, water, machinery and equipment, human labor, sheds, silos, among other components of the productive system, multiplied by their respective energetic coefficients. The total energy demand of a system in a production cycle for the production of 1 kg of live chicken and its energy efficiency coefficient were determined. The studied system had energy conversion coefficient of 95%,... |

| The reduction of the available phosphorus (avP) content in the broiler diet must be followed by the supplementation of adequate phytase. One experiment was conducted with broilers from 15 to 28 days of age to determine the level of necessary phytase when the mashed diet is formulated with 0.213% of avP to enable the results of performance, tibia ash content, and calcium (Ca) utilization similar to those determined for birds fed with diet formulated to meet their nutritional requirements. Thus, 120 broilers were distributed in (4+1) x2 factorial arrangement corresponding to four deficient diets in avP (0.213%) supplemented with phytase (0; 750; 1,500 or 2,250FTU kg-1) plus one positive control diet without phytase (0.426% of avP), supplied to male and... |
