Impact of copper (Cu) at the dose of 50 mg on haematological and biochemical blood parameters in turkeys, and level of Cu accumulation in the selected tissues as a source of information on product safety for consumers

Growth rate, metabolic parameters and carcass quality in turkeys fed diets with different inclusion levels and sources of supplemental copper

“…However, in the present study, the replacement of Cu-SUL with Cu-NP and the decrease in the dose of supplemental Cu from 20 mg/kg to 10 and 2 mg/kg did not affect the growth performance or the carcass quality of turkeys. In one of the few experiments performed on growing turkeys, the supplementation of bird diets with 50 mg Cu-SUL/kg did not induce changes in growth performance (Makarski et al, 2014). In the present experiment, the growth performance of birds and slaughter yield were similar in the compared treatments, regardless of the dose of supplemental Cu.…”

“…In broiler chickens, plasma Hb levels increased when diets were supplemented with 75-150 mg Cu/kg relative to the control group, whereas a decrease in plasma Hb levels was noted in response to the highest Cu dose of 250 mg/kg (Samanta et al, 2011). In an experiment performed on growing turkeys (Makarski et al, 2014), a dietary Cu-SUL dose of 50 mg/kg decreased Hb levels relative to the control group where the diet was not supplemented with Cu. In the present study, diets supplemented with up to 30 mg Cu/kg did not induce changes in Hb levels in growing turkeys.…”

Fattening turkeys with the addition of lactic acid and copper

“…The dead weight higher by 7% was obtained in the group supplemented with 30 mg of copper in the form of copper chelate with lysine, which correlates with own research. Higher copper levels in feeding stuffs are reflected in the higher concentration in tissues, which, as indicated by Makarski et al (2014), can constitute a valuable source of this element in everyday human diet and, consequently, can prevent diseases related to Cu deficiency. Probiotic milk acid bacteria show positive effects in the bird's digestive system.…”

Contenido De Metales Pesados (Cr, Cu, Zn, Pb Y Cd) en Sangre Y Plumas De La Codorniz (Coturnix Coturnix Japonica) Y Su Relación Con El Peso Y El Sexo De Las Aves

“…Sin embargo, ya que en muchos casos las aves están protegidas deontológicamente, es conveniente utilizar técnicas no invasivas para determinar contaminantes en sus tejidos, por ejemplo, a través de la obtención de pequeñas muestras de sangre y plumas (Burger, 1993). Las plumas tienen ventajas sobre otros tejidos pues son fáciles de recolectar y almacenar, ya que no necesitan refrigeración y se pueden extraer en vivo (Makarski et al, 2001;Adout et al, 2007). Por su parte, la sangre brinda información sobre la frecuencia de exposición, la…”

“…Las aves de corral han jugado un papel muy importante en el estudio de toxicidad por MP (Suganya et al, 2016), como ha sido demostrado en diversos estudios en pato (Anas platyyrhynchos L. 1758) (Szymczyk & Zalewski, 2003;Kinabo & Lyatuu, 2009;Binkowski & Meissner, 2013;Vega et al, 2011); pavo (Meleagris gallopavo L., 1758) (Makarski et al, 2001;Mikulski et al, 2009), codorniz (Coturnix coturnix japonica Temminck & Schlegel, 1849) (Debacker et al, 2001, El Okle & Lebda, 2014, Hamidipour et al, 2016, aunque siendo más ampliamente analizada en pollos para consumo, gallos y gallinas (Gallus gallus domesticus L., 1758) (Baykov et al, 1996;Demirbas, 1999;Uluozlu et al, 2009;Yang et al, 2011;Abduljaleel et al, 2012;Abduljaleel et al, 2013;Thirulogachandar et al, 2014;Manjula et al, 2015).…”
