| O objetivo deste trabalho foi avaliar os minerais séricos e as funções hepática e renal de frangos de corte, alimentados com dietas com aflatoxinas e dietas com aflatoxinas e argila clinoptilolita natural. Foram utilizados 528 frangos de corte machos, da linhagem Ross, distribuídos em seis tratamentos com quatro repetições cada: T1 - testemunha: ração sem aflatoxina ou clinoptilolita; T2 - ração com 5 ppm de aflatoxinas; T3 - ração com 0,25% de clinoptilolita; T4 - ração com 5 ppm de aflatoxinas e 0,25% de clinoptilolita; T5 - ração com 0,5% de clinoptilolita; e T6 - ração com 5 ppm de aflatoxinas e 0,5% de clinoptilolita. As aves foram submetidas aos tratamentos do 1º ao 42º dia de idade. Foram abatidos 72 animais, e foram analisadas as concentrações... |

| ABSTRACT Many kinds of feed additives can be used in chicken diets to stimulate intestinal morphological maturation and, consequently, intestinal function. The purpose of this study was to evaluate the effect of zeolite on broiler performance, gut morphology and gut digestive enzyme activity. The one-day old broiler chickens Ross 308 were assigned randomly into 3 groups with 30 birds per treatment. The 3 dietary treatments were: basal diet only (control group), basal diet + 2% zeolite, basal diet + 3% zeolite. Morphological and morphometric intestinal assessments were conducted using a light microscope. There was observed increase in villus height, villus perimeter, villus section area and crypt depth throughout duodenum and mid jejunum of the broilers fed... |

| The objective of the present study was to evaluate the effect of clinoptilolite and calcium levels on uric acid and calcium blood profile and bone quality of commercial layers. A total of 576 birds were distributed according to a completely randomized experimental design in a 3x4 factorial arrangement (calcium levels of 2.5, 3.1, or 3.7% and clinoptilolite levels of 0.0, 0.15, 0.25, or 0.50%), into 12 treatments with six replicates of eight birds per cage (experimental unit). The experimental period was 112 days. The experimental diets were based on corn and soybean meal. Results were submitted to analysis of variance and means were compared by the test of Tukey at 5% significance level using SISVAR statistical package. Blood uric acid was significantly... |

| In Brazilian agriculture, urea is the most commonly used nitrogen (N) source, in spite of having the disadvantage of losing considerable amounts of N by ammonia-N volatilization. The objectives of this study were to evaluate: N lossby ammonia volatilization from: [urea coated with copper sulfate and boric acid], [urea coated with zeolite], [urea+ammonium sulfate], [urea coated with copper sulfate and boric acid+ammonium sulfate], [common urea] and [ammonium nitrate]; and the effect of these N source son the maize yield in terms of amount and quality. The treatments were applied to the surface of a soil under no-tillage maize, in two growing seasons. The first season (2009/2010) was after a maize crop (maize straw left on the soil surface) and the second... |

| To study the effects of zeolite and selenium (Se) application on production and physiological attributes of three canola (Brassica napus L.) cultivars under water stress, an experiment was conducted in two growing seasons (2006 and 2007), at Karaj, Iran. The experimental design was randomized complete blocks in factorial split plot with three replications, and three factors: 1) irrigation: complete and restricted at stem elongation stage; 2) zeolite: 0 and 10 t ha-1; 3) Se (as sodium selenate): 0, 15 and 30 g L-1. These treatments were randomized into Zarfam, Okapi and Sarigol canola cultivars. According to the results, Zarfam cultivar showed the lowest electrolyte leakage and the highest biological yield due to zeolite application and 30 g L-1 Se. The... |

| Abstract Strains of Bacillus subtilis increase plant growth and yield. Consequently, the application of Mexican native strains of B. subtilis on greenhouse-grown melon (Cucumis melo L.) plants should induced a significant improvement on plant development and fruit quality. The objective of this study was to evaluate the effect of LAL-36, BEB-23, BEB-22 and BEB-13 B. subtilis strains, native to Mexico, on melon plant development and fruit quality. The strains were placed separately into the rhizosphere of melon plants under greenhouse conditions. Plants were grown in clinoptilolite type zeolite. Five treatments were evaluated: four inoculated with one of the four B. subtilis strains and one control without bacterial inoculum. A completely randomized design... |

| Abstract The objective of this study was to evaluate NBPT, zeolite and humic acid in different concentrations as inhibitors of the activity of the enzyme urease. The activity of the urease enzyme was quantified by the methods proposed by May and Douglas (1976) and Witte and Medina-Escobar (2001). For this reason, two experiments were conducted in a completely randomized design in split plots, in which the incubation periods are the plots and the fertilizers with the inhibitors at the different concentrations are the subplots with three replications. Fifteen fertilizers based on NBPT-coated urea, humic acid and zeolite were used in different concentrations. The two methods of analysis used in the experiment confirmed the efficiency of NBPT in inhibiting the... |
