this study was conducted to determine the effects of different levels and sources of copper supplementation on hematological values, ceruloplasmin and plasma copper, zinc and iron status in mehraban male lambs. twenty growing lambs were randomly allotted to four different treatments. treatments consisted of 1) 10 mg/kg cu in the form of cuso4, 2) 20 mg/kg cu in the form of cuso4, 3) 10 mg/kg cu...

serum level of zinc, copper, β-carotene, vitamin a, and concentrations of zn and cu in hoof of 97multiparous holstein dairy cows with different locomotion scores (lss) were evaluated. simultaneously, znand cu concentrations of close up, fresh and high yielding cattle rations were 77, 94, 75 and 31, 28, 22 ppm, respectively. based on lss, despite normal serum copper levels in all three groups, w...

in order to study the effect of different levels of nitrogen and copper on yield and nutrients concentrations and nitrate in broccoli head, an experiment was conducted based on a factorial combinations of five levels of nitrogen (0, 100, 200, 300 and 400 kg/ha) and three levels of copper (0, 2.5 and 5 kg/ha) that were applied to soil as ammonium sulfate and copper sulfate respectively, in three...

To determine the efficiency of copper (Cu) supplementation, a feeding experiment was carried out with 240 day old broiler chicks (vencobb-100). Birds were divided into four dietary treatments: i) C no additives, ii) T1-75 mg inclusion of Cu/kg diet, iii) T2-150 mg inclusion of Cu/kg diet, iv) T3-250 mg inclusion of Cu/kg diet. The present study was carried out in the Department of Animal Physio...

the effect of different levels of zinc and copper organic supplements on performance, plasma copper plus zinc status, serum alkaline phosphatase (alp), ceruloplasmin (cp) activity as well as vitamin ¬a concentration was studied in 25 mehraban male lambs each of 5-6 months of age and 30/64±3/47kg of live weight. the following five dietary treatments were used: 1) control (base diet with no addit...
