The objective of this study was to determine the crude protein requirements for juvenile jundiara fish, a hybrid of Pseudoplatystoma fasciatum X Leiarius marmoratus. A total of 240 juveniles of the hybrid, with an initial mean weight of 8.4 ± 1.41 g, were distributed in 15 fiberglass tanks (170 L) in a closed water recirculation and constant aeration system, with a density of 16 fish/tank. The experimental design was completely randomized with five treatments and three replications. The treatments consisted of diets with 32, 34, 36, 38 and 40% crude protein. Seventy days into the experiment the final fish weight and feed intake were measured. Two specimens from each experimental unit were collected for evaluation of carcass chemical composition, nutritional efficiency and blood parameters. The increase in crude protein content promoted the significant, increasing linear effect for mean weight gain, mean feed intake and specific growth rate, and decreasing effect for feed conversion. Significant differences were also observed in carcass chemical composition, nutritional efficiency, total plasma protein, glucose, cholesterol, triglycerides and lipase enzymatic activity. Thus, the increase in crude protein levels of up to 40% in jundiara diets promotes improvement in the productive performance of juvenile jundiara.

Abstract The compositions of lipopolysaccharides from the photoheterotrophic budding Rhodomi­crobium vannielii strains DSM 162, Rm5, E3 and 2/1 are reported. Common constituents of these lipopolysaccharides are glucose, mannose, glucosamine, glucuronic and galacturonic acids, 2-keto-3-deoxyoctonate (KDO) and the fatty acids 3-OH-C16:0, 3-OH-C14:0, C14:0, Δ14-C22:1, aside from strain specific differences. Two different, medium-dependent growth forms of strain DSM 162 are described. The vitamin/ yeast extract-concentration in the medium and/or the growth temperature were found as factors triggering the different growth forms. Lipopolysaccharides of the two growth forms had only quantitative differences in composition. Lipopolysaccharide from swarmer cells of strain Rm5 showed a chemical composition comparable to that of chain cells and from simple cycle cells of the same strain.

The aim of the study was to determine the influence of Cu-glycine chelate on the chemical composition of the liver and blood parameters of broiler chickens. A total of 250 one-day-old Ross 308 male chicks were allotted into 5 groups with 5 replicates of 10 birds each. Rearing of birds lasted 42 days. In the experiment Cu was added to the premix in the form of CuSO4 (16 mg, 8 mg Cu), and in the form of Cu glycine chelate (16 mg, 8 mg, 4 mg Cu). The parameters in the chickens’ blood remained within the range of physiological norms when lower levels of the analyzed elements were added. Adding lower levels of Cu (8 or 4 mg kg-1) in comparison with the recommended doses (16 mg kg-1) for broilers, in the form of highly assimilable organic sources, did not reduce the content of minerals Cu, Fe, and Zn in the chickens’ liver, but reduced the faecal Fe, Cu and Zn concentrations compared to CuSO4.

The analysis of literary data on the obtaining of cyclic carbonates based on the vegetable oils has been carried out. The influence on carbonation reaction the type of vegetable oil, the chemical composition and catalyst concentration, state of carbon dioxide, pressure and temperature have thus been considered. The carbonation process of epoxidized oils that are valuable renewable vegetable raw materials is studied insufficiently.
