“…Figure 4 illustrates the low extraction by Cu Tifton 85 grass. Lima and Miyada (2003) conducted an experiment with Cu in the form of cupric citrate, a more soluble source with greater utilization by the animal and less waste left in the excretions. Thus, they concluded that cupric citrate may replace the Cu sulfate, contributing to reducing this nutrient in the SW. SW in any of the doses could supply the manganese (Mn) needed for the production of Tifton 85 grass (Figure 4c).…”

Swine wastewater (SW) is considered as a source of nutrients for agriculture. The quantities and frequencies applied may vary according to the soil class, the nature and composition of the waste, the climatic conditions and the cultivated plant species. Therefore, this study aimed to evaluate the effects of application of five Swine wastewater doses (0, 500, 1000, 2000 and 2500 m³ ha-1) in the production of components and grass nutrient extraction Tifton 85 and changes in soil chemical properties after the end of the last application of swine wastewater. To achieve these goals, we evaluated the quantities of extracted nutrients, density and height of the pre-grazing grass, forage accumulation rate and carrying capacity. The experimental design was a randomized block. The production of dry matter was 18159.80 kg ha-1 , and the average height of 85 Tifton was 34.83 cm. The higher carrying capacity, 10 AU ha-1 was obtained with the dosage of 2500 m³ ha-1. While, the dose of 2000 m³ ha-1 supplied the nutritional needs of Tifton 85 in nitrogen, potassium, calcium, magnesium, copper, iron, zinc and boron. The quantities of extracted nutrients (kg ha-1) at grass Tifton 85 grazed were: N = 405.14; P = 57.77; K + = 387.69; Ca 2+ = 77.05; Mg 2+ = 49.68; S-SO4-2 = 31.48; B = 0.33; Cu 2+ = 0.20; Fe = 2.88; Mn 2+ = 4.61; Zn 2+ = 2.86. The application of increasing doses of SW promoted a linear increase in grass production components Tifton 85, as well, promoted changes in soil chemical properties and quantities of extracted nutrients.

RESUMO -Foram conduzidos dois experimentos para avaliar fontes orgânicas e inorgânicas de zinco e cobre nas dietas e seus efeitos no desempenho de leitões desmamados aos 21 dias de idade. Em cada experimento, foram utilizados 90 leitões em delineamento experimental de blocos ao acaso, com cinco dietas, seis repetições e três animais por parcela. As dietas utilizadas nos experimentos 1 e 2 continham 120 ppm de zinco e 10 ppm de cobre na forma de sulfato. No experimento 1, foram suplementadas com 0, 300, 600 e 900 ppm de zinco na forma orgânica ou 2.400 ppm na forma de óxido (ZnO) e, no experimento 2, com 0, 50, 100 e 150 ppm de cobre na forma orgânica ou 240 ppm de cobre na forma de sulfato (CuSO 4 H 2 O). No experimento 1, os níveis de zinco de fonte orgânica tiveram efeito linear no consumo de ração e no ganho de peso nos períodos de 0 a 15 dias e de 0 a 21 dias pós-desmame. O ganho de peso nas fases de 0 a 35 dias e de 0 a 42 dias pós-desmame e o consumo de ração dos leitões que receberam a dieta com 900 ppm de zinco de fonte orgânica não diferiram dos valores observados naqueles que receberam a dieta com 2.400 ppm de zinco na forma inorgânica. A suplementação da dieta com zinco na forma orgânica (900 ppm) ou inorgânica (2.400 ppm) aumentou o consumo de ração e o ganho de peso de leitões nas primeiras três semanas após o desmame. A suplementação da dieta com 2.400 ppm de zinco na forma inorgânica reduziu a incidência de diarreia nas primeiras três semanas pós-desmame. No experimento 2, os níveis de cobre de fonte orgânica tiveram efeito quadrático no consumo de ração dos leitões nos períodos de 0 a 31 e de 0 a 40 dias pós-desmame. A suplementação da dieta com cobre, tanto de fonte orgânica (90 ppm) como inorgânica (240 ppm), aumenta o consumo de ração e o ganho de peso de leitões nos primeiros 40 dias pós-desmame.Palavras-chave: desempenho, diarreia, minerais, suínos Organic and inorganic source of zinc and cooper as growth promoters for weanling pigletsABSTRACT -Two experiments were conducted to evaluate organic and inorganic sources of zinc and copper and their effects on performance of piglets weaned at 21 days of age. In each experiment, it was used 90 piglets in a randomized block experimental design with five diets and six replications and three animals per plot. The diets used in experiments 1 and 2 contained 120 ppm zinc and 10 ppm copper as sulfate. The diets of experiment 1 were supplemented with 0, 300, 600 or 900 ppm of zinc in organic form or 2,400 ppm as zinc oxide (ZnO) and in the experiment 2, the diets were supplemented with 0, 50, 100 and 150 ppm copper in organic form or 240 ppm copper as sulphate (CuSO 4 H 2 O). In the experiment 1, levels of zinc from the organic source linearly affected on feed intake and weight gain from 0 to 15 days and from 0 to 21 days post weaning. Weight gain in the 0 to 35 day phase and from 0 to 42 days post-weaning and feed intake of the piglets fed diet with 900 ppm zinc from organic source were not different from the values observed on those fed diet 2,400 ppm ...
