Valor nutricional da soja integral tostada e extrusada para poedeiras comerciais

An experiment was conducted to determine the apparent nitrogen-corrected metabolizable energy (AMEn) values and the coefficients' metabolization of the: dry matter, ether extract, calcium and phosphorus availabilities of experimental layer diets containing toasted (TSB) and extruded (ESB) soybeans. The soybean meal (SBM) was substituted at 0, 50, and 100% by TSB and ESB whole soybeans. The whole soybeans utilization in layer diets did not adversely affect calcium and phosphorus availability. The SBM and ESB, in diets with crude protein at 17%, showed the best ether extract coefficients of metabolization. When TSB replaced all SBM in the diets, it was observed the worst value for AMEn.

Efeito de Diferentes Níveis de Manganês e Fósforo Sobre o Desempenho e a Qualidade da Casca dos Ovos de Poedeiras Comerciais

The objective of this experiment was to evaluate the different levels of manganese and phosphorus (P) on the performance and eggshell quality and on determined blood constituents of 96 laying hens Hy-Line W36, with 60 weeks of age, distributed in 24 lots with four hens each. A completely randomized experimental design was used in a factorial arrangement (3x2), manganese levels (70, 140 and 210 ppm) and total phosphorus levels (.35 and .55%), totalizing six treatments with four replicates each. The experimental diets were isoproteic (16.0% CP), isocaloric (2800 kcal ME/kg), isocalcium (4.0% Ca) and isosodium (.16% Na). The manganese levels did not alter the production and eggshell quality. However, when hens were fed diets containing .35% of total P, there were observed decreases in the egg production, egg weight and egg mass, without alterations in eggshell quality characteristics. The supplemental manganese levels were not effective to improve eggshell quality at the final phase of production. The total phosphorus level of .35% was inadequate for the laying hens to express the normal production characteristics.

Comparação de métodos de determinação da gravidade específica de ovos de poedeiras comerciais

The objective of this work was to compare the results of measuring the specific gravity (SG) of laying hen eggs by using a weighing apparatus and the saline flotation method (SFM). Two hundred eggs from two genetic lines were distributed randomly into two groups of 50 eggs per genetic line and were submitted to two different sequences of SG measurement. Not significant differences were found between the two methods. The weighing apparatus measured the SG of the eggs accurately as the SFM.

Testes de biocompatibilidade in vitro de duas formas comerciais do agregado de trióxido mineral

Recently, regular and white mineral trioxide aggregate (MTA) are being used in Dentistry as retrofilling materials. Genotoxicity and cytotoxicity tests form an important part of cancer research and risk assessment of potential carcinogens. Thus, the goal of this study was to examine the genotoxicity and cytotoxicity of regular and white MTA in vitro by the single cell gel (comet) assay and trypan blue exclusion test, respectively. Mouse lymphoma cells were exposed to two presentation forms of MTA at final concentrations ranging from 1 to 1,000 μg/mL for 3 h at 37°C. The results showed that both compounds tested did not produce genotoxic effects at all concentrations evaluated. Likewise, no statistically significant differences (p > 0.05) were observed in cytotoxicity. Taken together, our results suggest that regular and white MTA are not genotoxins and are not able to interfere in cellular viability as assessed by single cell gel (comet) assay and trypan blue assay, respectively.

Digestibilidade de uma dieta caseira e dois alimentos comerciais, econômico e super-prêmio, para cães

They were compared the coefficients of apparent digestibility (CAD) and the fecal quality of dogs fed a home-made diet and two dog foods, standard and super-premium. Six adult dogs were distributed in a double latin square desing (3 × 3), with three treatments and three periods, in a total of six replications per treatment. Tukey's test was used to compare the means. The home-made diet presented the highest CAD, not differing only of the CAD of acid ether extract of the super-premium food. The standard food was the lowest digestive, producting more feces. Fecal dry matter of dogs fed home-made diet was lower than in the standard and super-premium foods, which did not differ among then. Fecal score presented low variability among treatments, remaining in the considered ideal range. Home-made diet can be an alternative in the feeding of dogs.
