This experiment was conducted to determine the performance and carcass yeld of broilers fed diets based on increasing whole rice meal levels (WRM), with or without multienzyme complex supplementation. Nine hundred and sixty Cobb chicks, males and females, were allocated in a completely randomized design with eight treatments and six replicates with 20 birds. Four levels of WRM (0%, 10%, 20% and 30%), with and without supplementation of a multienzyme complex composed of protease, pentosanase e phytase enzymes were used in the experiment. The diets had the same levels of energy, protein, calcium and phosphorus in all the treatments. With the use of increasing levels of whole rice meal, there was significant reduction (P 0.05), however, in the diets supplemented with enzymes, the bio-economic index was 1.4% higher than the diets without supplementation.

Este trabalho teve por objetivo isolar, identificar e selecionar isolado(s) de Fusarium spp. em sementes de pepino e verificar a sua influencia na qualidade fisiologica. Foram utilizados tres sublotes e os tratamentos consistiram em: testemunha absoluta; BDA + manitol - 0,8Mpa; BDA; BDA + manitol - 0,8Mpa + fungo; e BDA + fungo. A qualidade fisiologica foi avaliada atraves de testes em laboratorio e casa de vegetacao. Cinco isolados de Fusarium verticillioides foram identificados e a sua transmissao atraves das sementes para plantas nao foi possivel afirmar. A tecnica da restricao hidrica foi eficiente para proporcionar infeccao das sementes, sabendo que e o fungo influencia negativamente na qualidade fisiologica das sementes de pepino da cultivar Caipira.

The objective of this work was to study the effect of the growing levels of whole rice meal (WRM) on the performance of broilers chickens and to evaluate the reduction of the calcium (Ca) and phosphorus (P), when the diets were supplemented with enzymes exogenous. A total of 480 chicks (females) Cobb 12 days old were used, distributed in 8 treatments evaluating 4 levels of WRM (0%, 10%, 20% and 30%), with and without supplementation of a multienzyme complex, with 3 repetitions of 20 poultries for treatment. In the diets that contained enzymes, the levels of Ca and P were decreased in 0,1%, in all the development phases. With the addition of growing levels of Whole rice meal in the diets, there was a significant lineal regression (P 0.05). The enzymatic supplementation in the different levels of WRM didn’t present significant statistical difference. The use of low levels of Ca and P didn’t harm the acting of the birds.

The aim of this study was to evaluate the effect on the physiological performance of maize seeds (Zea mays L.) of micro-priming with Bacillus subtilis associated with techniques of water restriction and seed-coating. The micro-priming of the seeds, without any additional techniques, was carried out using a commercial product, Rhizoliptus ® (Bacillus subtilis). Water restriction was carried out using a PDA medium (Potato - Dextrose - Agar) with mannitol (-0.7 MPa), upon which the culture was grown for 48hours. One hundred sterilized corn seeds were placed in each dish. Once root protrusion occurred in one seed, the rest were removed and kept in a laboratory environment for 48 hours. The coating was carried out by the addition of Seed Polymer Color HE (50 ml kg -1 ) to the priming mixture containing theBacillus subtilis. The seeds were kept for 48 hours in a laboratory environment. A treatment which associated seed coating and water restriction was used on the micro-primed seeds, together with a control treatment without the addition of Bacillus subtilis. The Bacillus subtilis has no effect on the health of the seeds it; does however contribute to the growth and development of the maize seedlings, being influenced by the micro- priming technique used. The use of water restriction associated with seed coating provides better results when micro-priming with Bacillus subtilis.
