“…Copper is usually fed commercially at much higher pharmacological levels (125 to 250 mg/kg) because of its growth promoting properties, which is caused by its antibacterial properties (Pesti and Bakalli, 1996). In the present study, Cu resulted in a significant increase in BW gain during 21 to 42 and overall.…”

An experiment with 495 one-day-old male broiler chicks was conducted to investigate the effects of different dietary levels of canola meal (0, 10, 20%) and copper (0, 125, 250 mg/kg) on performance, carcass characteristics and some blood parameters. A completely randomized design with 3×3 factorial arrangement was used with 5 replicates from 1 to 42 of age. Feed intake was not significantly affected by treatments during 1 to 21 d, 21 to 42 d and throughout the study (P＞0.05). The body weight gain and feed conversion ratio was significantly impaired (P＜ 0.05) when 20% canola meal was added in the diets between 1 to 21 d. Addition of copper significantly improved body weight gain (P＜0.01) and feed conversion ratio (P＜0.05) of the birds during the 21 to 42 d and throughout the study. Carcass yield significantly (P＜0.05) increased due to addition of 250 mg/kg of copper. Proportion of thyroid glands (P＜0.0001), breast, liver, gizzard, pancreas and cecal significantly (P＜0.05) were affected by 20% canola meal. Plasma alkaline phosphatase and blood glutathione peroxidase activities were unaffected (P＞0.05) by dietary treatments. An added level of 20% canola meal was significantly reduced plasma zinc concentration. Levels of copper supplementation increased (P＜0.001) plasma copper and decreased (P＜0.05) plasma zinc levels. Plasma lipids altered by supplementation of copper, so that decreased plasma triglycerides (P＜0.01) and cholesterol (P＜ 0.05) concentrations and also increased high density lipoprotein (P＜0.05). In conclusion, the results of this study indicate that no effects of added canola meal up to 20% of the diet on the growth performance. In addition from this study it can conclude that supplementation with dietary copper had beneficial effects on growth performance and plasma biochemical characteristics of broiler chickens.

“…Este resultado contraria o obtido por Pesti & Bakalli (1996), que observaram melhor valor de conversão alimentar (1,496) em frangos de corte aos 21 dias de idade ao utilizarem 250 mg de sulfato cúprico pentahidratado nas rações. Os resultados de conversão alimentar obtidos neste estudo foram piores que os citados no Manual de Criação (Granja Planalto, 2006), de 1,36.…”

RESUMO -Objetivou-se avaliar os efeitos de diversos níveis de alho e cobre sobre o desempenho produtivo, as características de carcaça e os teores de colesterol no soro e nos tecidos de frangos de corte. Foram utilizados 400 pintos machos Cobb nos primeiros 21 dias de idade, distribuídos em delineamento inteiramente casualizado em esquema fatorial 3 × 3, composto de três níveis de alho (0, 1,5 e 3,0%) e três de cobre (0, 125 e 250 mg/kg ração), na forma de sulfato de cobre. Foram realizados dois abates -o primeiro aos 21 dias e o segundo aos 42 dias de idade das aves -para coleta de sangue e tecidos e determinação dos teores de gordura e colesterol. Os resultados obtidos comprovaram que a suplementação de alho e cobre nas rações, apesar de prejudicar a conversão alimentar das aves na fase de 1 a 21 dias de idade, promoveu reduções dos teores de gordura no peito(1 a 21 dias) e de colesterol sérico (22 a 42 dias).Palavras-chave: alimentos, avicultura, colesterol, desempenho produtivo, gordura, produtos alternativos Use of garlic and copper in the feeding of broiler chicksABSTRACT -Four hundred male Cobb chicks were used in an experiment to study the effects of different dietary levels of garlic and copper on the performance, carcass characteristics and serum and tissue cholesterol levels of broiler chicks. The experimental period was comprised between the first 21 days of age of the birds. A completely randomized design was used in a factorial 3 × 3 with the following levels: garlic (0, 1.5, and 3.0%) and copper (0, 125, and 250 mg/kg of ration), in the form of copper sulfate. Two slaughters were realized, the first at 21 days, and the second at 42 days of age of the chicks. Samples of blood and tissues were collected to the determination of fatty acids and cholesterol. The results showed that the supplementation of garlic and copper in the diets may be done without great effects on the performance of the birds and it can result in reduction on serum and cholesterol tecidual of the broilers.

“…Copper is often added to poultry feeds in increased quantities for preventive purposes because it stimulates the weight gain (Pesti & Bakalli 1996). In practice, however, there is often a copper deficiency in turkeys, with the reason being the presence of phytates and phosphates in feed as well as the antagonism with some chemical elements, for example, between Zn and Cu (Pang & Applegate 2007).…”

The paper presents results of research on the effects of different doses of copper in the form of CuSO 4 ·5H 2 O and Cu chelate and lysine (1:2), also with 0.4% lactic acid in drinking water on weight gain of turkeys. The study sample consists of 20 experimental groups of 120 birds each. The addition of lactic acid to the feed (excluding copper) contributed slightly to the reduction of the weight gain of turkeys. In contrast, a significant decrease in body weight gain of turkeys was observed, using lactic acid along with inorganic form of copper. Turkeys fed with the feed containing only organic form of copper at a dose of 20 mg reached the greatest weight gain. Lactic acid and different doses and forms of copper significantly differentiate the body weight gain of turkeys. The combination of the lactic acid and copper added resulted in lower weight gains of birds; it was only the administration of the 50 mg copper dose in organic form that increased the weight gain to the level comparable to the weight gains obtained for birds fed without the lactic acid addition. The use of feed supplements requires the selection of an appropriate dose to the form of copper. ARTICLE HISTORY
