“…High levels of Cu have also been used in broiler diets because of increases noted in production, such as improved weight gains. Johnson et al (1985) found that diets containing 125 mg Cu kg −1 (as copper sulfate) resulted in improved weight gains. They found that the mold counts in litter of birds grown with additional Cu were 95% lower than that of the control diet and suggested that high levels of Cu in the litter (600 mg Cu kg −1 ) resulted in reductions in mold, which was the cause of improved weight gains.…”

Arsenic (As) and copper (Cu) runoff from fields fertilized with poultry litter has received increasing attention in recent years, although it is not known if heavy metal runoff from poultry litter poses a significant threat to the environment. The objective of this study was to determine the main factors affecting As and Cu concentrations in runoff water from pastures receiving poultry litter applications. Rainfall simulation studies were conducted to determine the effects of the following treatments on metal runoff: (i) aluminum sulfate (alum) additions, (ii) diet modification using phytase or high available phosphorus corn, (iii) fertilizer type, (iv) poultry litter application rate, and (v) time until the first runoff event occurs after poultry litter application. Results showed that alum additions to poultry litter significantly decreased As and Cu concentrations in runoff water. Copper concentrations were highest in runoff from poultry litter from birds fed phytase diets compared with other diets; however, this effect may have been a result of wet storage conditions rather than diet. Triple superphosphate applications resulted in the lowest heavy metal concentrations in runoff water among all fertilizer treatments, while normal poultry litter resulted in the highest concentrations. Arsenic and Cu concentrations increased in runoff water as poultry litter application rates increased and decreased with increasing time until the first runoff event. These data indicate that adding alum to poultry litter, a cost-effective best management practice, which also results in lower P runoff and ammonia emissions, may also be an effective tool in reducing metal runoff.

“…Various elements are added to poultry rations, such as As, Co, Cu, Fe, Mn, Se, and Zn (Moore, 1998). Copper sulfate is often added to the diet of broilers to increase weight gain and avoid diseases (Johnson et al, 1985). Other elements are added to feed so that young birds can tolerate various stresses under high‐population conditions in the house (Tufft and Nockels, 1991).…”

An understanding of the long-term cycling of trace elements in soil with broiler litter fertilization under various forage utilization strategies is needed to develop sustainable agricultural production systems. We evaluated differences in Cu, Mn, Zn, and six other trace elements in response to 5 yr of bermudagrass [Cynodon dactylon (L.) Pers.] management varying in fertilization and harvest strategies on a Typic Kanhapludult in Georgia. Chicken (Gallus gallus) broiler litter was a significant source of trace elements that led to 3.4 +/- 0.5 times higher Cu, 2.0 +/- 0.3 times higher Mn, and 2.1 +/- 0.2 times higher Zn in the surface 3 cm of soil than when forage was fertilized inorganically. There were variable effects of broiler litter fertilization on other trace elements, depending upon element, depth of sampling, and forage utilization strategy. Concentrations of all trace elements in soil were below levels considered toxic to plants. Soil at a depth of 0 to 3 cm under grazed paddocks had 33 +/- 5% greater Cd, 18 +/- 1% greater Cr, 53 +/- 24% greater Cu, and 24 +/- 7% greater Zn compared with unharvested and hayed management. Trace elements in soil were unaffected whether forage was unharvested or removed as hay. These results suggest that broiler litter is a significant source of several trace elements and that ruminant processing of forage and subsequent deposition of excreta on the paddock allow these trace elements to accumulate more at the soil surface where they might interact with the high concentration of organic matter.

“…Johnson et al (1985) tested the effect of 125 mg Cu kg -1 (cupric sulfate) in broiler chicken diet on the performance and the concentration of this mineral in the litter, and its effects on the microflora in four successive trials carried out during a 12-month period, without changing the bedding. The authors did not find differences in bird growth and feed conversion efficiency for the first and second trials.…”

Feeding cupric citrate as alternative to cupric sulfate to broilers has been suggested in the literature. Day-old male broiler chicks (1,200) were used in an experiment to evaluate the efficacy of cupric citrate supplementation (75 mg Cu kg , 1-42 d). A randomized block design was used, with five treatments, six replicates and 40 birds per pen. The diets, based on corn and soybean meal, and water were offered ad libitum during the 42-day experimental period. Over the entire period, there was no effect of copper supplementation (P > 0.05) on bird live weight, weight gain, feed intake, feed conversion and mortality. Cupric citrate supplementation on the 22-42 d period resulted in worse feed conversion as compared to broilers receiving cupric sulfate (2.014 vs. 1.967, P < 0.05). Copper residues in the litter were reduced when broilers were fed cupric citrate, as compared to cupric sulfate (P < 0.01). The absence of response to copper supplementation can be attributed to the environmental and sanitary rearing conditions.

Este trabalho avaliou a eficácia do citrato cúprico em diferentes fases da criação de frangos de corte. Foram utilizados 1200 pintos machos, em um experimento em blocos casualizados, com cinco tratamentos, seis repetições e 40 aves por parcela. Os tratamentos consistiram de uma dieta não suplementada ou suplementada com citrato cúprico anidro (75 mg Cu kg -1 ) de 1 a 21 dias, de 22 a 42 dias ou de 1 a 42 dias, ou com sulfato cúprico pentahidratado (200 mg Cu kg -1 ) de 1 a 42 dias. Foram avaliados o desempenho das aves e o resíduo de cobre na cama. Dietas, à base de milho e farelo de soja, e água foram fornecidas à vontade durante todo o período experimental. Não houve efeito da suplementação de cobre (P > 0,05) sobre o peso vivo, ganho de peso, consumo de ração, conversão alimentar e mortalidade mais refugagem. Os frangos que receberam citrato cúprico na ração a partir dos 22 dias tiveram, no período 22-42 dias, conversão alimentar pior que aqueles que receberam sulfato cúprico ( 2,014 vs. 1,967, P < 0,05). O resíduo de cobre na cama das aves que receberam citrato cúprico na dieta foi reduzido em comparação às que receberam sulfato cúprico (P < 0,01). O cobre não resultou em efeito promotor de crescimento em função das condições ambientais e sanitárias do experimento. Palavras-chave: aves, cobre, cama de frango, desempenho
