This study evaluated different cooking processes (roasted, cooked and fried) on total mercury (Hg) content in fish species most consumed by Manaus residents and surrounding communities, Amazon region. The results obtained for total Hg in natura and after the three types of preparation (roasted, cooked and fried) for 12 fish species showed a significant Hg concentration variation. In the present study the cooked and frying processes resulted in higher Hg losses for Pacu, Pescada, Jaraqui, Curimatã, Surubin and Aruanã fish species, most of them presenting detritivorous and carnivorous feeding habits. The higher Hg losses in the roasting process occurred for Sardinha, Aracu, Tucunaré, Pirapitinga, Branquinha and Tambaqui fish species, most of them being... |

O objetivo do trabalho foi estudar o efeito de diferentes soluções nutritivas sobre a nutrição de micronutrientes em mudas de goiabeira. Foram avaliadas duas cultivares, Paluma e Século XXI, e quatro soluções nutritivas, em esquema fatorial (2x4) com três repetições. Aos 90 dias de cultivo hidropônico, avaliou-se a massa seca e a nutrição de micronutrientes em mudas. As mudas de goiabeira da cultivar Paluma apresentou maior desenvolvimento e exigência nutricional em boro, ferro e manganês, comparado a cultivar século XXI. As soluções nutritivas estudadas não afetaram o acúmulo e também as eficiências de absorção e utilização de micronutrientes das mudas de goiabeira, exceto o cobre e zinco, independentemente da cultivar. |

This study aimed to evaluate the effect of feed restriction on the ingestive behavior of Guzerat and Sindhi heifers. A total of 36 heifers were used, 18 from each breed, randomly distributed in a completely randomized design, in a 2 x 3 factorial scheme. The treatments used were 20 and 40% restriction compared to intake by animals from the third group, which were fed ad libitum (without restriction). For the behavioral analysis, the scan sampling method was used by logging and recording times in five-minute intervals during 24 hours, thus estimating the time spent feeding, ruminating and idling. With regard to the imposed restrictions, it was observed that non-restricted animals showed greater feeding time and lower resting time (p < 0.05); the two... |

The objective of this study was to determine the effect of replacing FM with mealworm (Tenebrio molitor) on the growth performance and immunologic responses of white shrimp. In addition, the toxicity of such replacement to white shrimp was measured. Mealworm was incorporated to partially or totally replace fish meal in diets for white shrimp. Experimental groups of shrimp with an average initial body weight of 2.39 ± 0.49 g were fed each of 4 isonitrogeneous diets formulated to include 0, 25, 50 and 100% (control, MW25, MW50 and MW100 respectively) of mealworm substituted for fish meal. After eight weeks of feeding trials, shrimp fed diets MW25, MW50 and MW100 had higher live weight gain (10.05 ± 3.06, 11.41 ± 2.08, and 10.36 ± 1.57, respectively),... |

This study evaluated the effect of different levels of canola meal in the diet to laying Japanese quails on productive performance, egg quality and economic viability. A total of 120 80-day-old Japanese quails (Coturnix coturnix japonica) with average weight 146.54 ± 12 g were evaluated during 84 days. Dietary treatments consisted of the replacement of soybean meal with canola meal at 0, 10, 20, 30, 40 or 50%. We evaluated economic viability, productive performance, internal and external quality of eggs. Data were analyzed by polynomial regression at 5%. Body weight decreased linearly as the level of canola meal increased (p = 0.0055). Egg weight (p = 0.0032) and diameter (p = 0.0398) showed a quadratic response, increasing up to 30% substitution with... |
