“…Based on the data of the present study, there was an improvement in the weight gain of infected lambs that were treated with copper (G3 and G4) when compared with G1 and G2. This result is similar to that reported in a previous study, in which sheep supplemented with copper exhibited an increased feed conversion rate when compared to untreated groups [ 28 ].…”

“…Kumar et al [ 27 ] observed no changes in the protein profile of uninfected lambs treated with different concentrations of selenium. Dezfoulian et al [ 28 ] found no differences in the red blood cells, hemoglobin and hematocrit of uninfected animals treated with different concentrations of copper. Therefore, the alterations in the protein profile observed in the present study occurred as a result of the parasitic infection and/or the additional effect from both Cu and Se on the immune system in response to the infection.…”

“…A copper deficiency has been associated with impaired macrophage respiratory burst capacity and lower prostaglandin and leukotriene formation, causing a greater risk of infections [ 33 ]. Copper supplementation promoted an increase in serum globulin levels in lambs, possibly due to an increase in gamma globulin, which tends to improve the immune response to parasites [ 28 ].…”

BackgroundGastrointestinal nematodes cause significant economic losses in the sheep industry, with frequent reports of anthelmintic resistance. Therefore, alternative methods to control these parasites are necessary. Thus, the aim of the present study was to assess the effect of treatment with selenium and copper on the protein profile of sheep that were experimentally infected with Haemonchus contortus.MethodsTwenty-eight lambs were experimentally infected with H. contortus and divided into four experimental groups as follow: G1 - untreated animals; G2 - treated with sodium selenite; G3 - treated with copper; G4 - treated with sodium selenite and copper. The serum protein, body weight and egg count per gram of feces (EPG) were assessed at the baseline and after 20, 40, 60 and 80 days. The parasite burden was assessed 80 days after the beginning of the experiment.ResultsHigher levels of total protein and gamma globulin were observed in the lambs treated with sodium selenite and copper on D80. Copper acted as a growth promoter. The copper-supplemented groups exhibited higher daily and total weight gain. The association of selenium and copper altered the protein profile of sheep. Copper and selenium supplementation reduced EPG and worm burden at the end of the experiment. To the best of our knowledge, this is the first study to demonstrate the positive effect of the combined parenteral supplementation of Se and Cu on H. contortus infection.ConclusionsThis injectable supplementation could be used as an auxiliary method to control H. contortus in sheep.

“…of life sciences [18,19]. Copper is one of the essential trace mineral elements in the animal body, which plays an important role in growth and development [20]. New organic copper sources have become the focus of current industry; they are better utilized than the inorganic ones, which solve problems related to using high doses of inorganic copper [21,22].…”

This study investigated the influence of dietary supplementation with some antibiotic alternatives on growth performance, intestinal barrier, and immunity of lipopolysaccharide (LPS) challenged chicks. Wenshi females, aged 4 days, were allocated randomly into eight groups, each with six replicates of 20 birds (n = 120/treatment), which received a basal diet supplemented with 0 (control), 0 (LPS), 200 mg/kg aureomycin, 50 mg/kg mushroom polysaccharide, 100 mg/kg mushroom polysaccharide, 500 mg/kg nano-copper, 300 mg/kg copper loaded chitosan, and 500 mg/kg lysozyme for 21 days. On day 18 and 20, the control birds were injected with 0.5 mL saline solution, the other treatments were injected with 0.5 mL saline containing 500 µg LPS/kg body weight (BW). The results indicated that LPS treatment reduced the BW, average daily gain (ADG), and daily feed intake (ADFI) than the controls (p < 0.05), and the antibiotic and the tested alternatives could not retrieve the normal BW, ADG, and ADFI. The tested additives reduced several negative effects of LPS; they reduced diamine oxidase activity and inflammatory mediators in plasma, jejunal mucosa, spleen and thymus, increased content of immunoglobulin in plasma and jejunal mucosa, and decreased gene expression of inducible nitric oxide synthase and Cyclooxygenase 2 in jejunal mucosa.

Antioxidantes 2. Colesterol 3. Enzimas 4. Minerais. I. Título. 12 months for study of oxidative stability. After that, steaks of m. longissimus were collected and exposed to "display life" (DL) (4°C) to study oxidative stability which was accompanied by TBARS values on days 0, 3 and 6. The copper supplementation resulted in higher concentration and accumulation of Cu in the liver (P<0.05), however, the concentration of Cu in muscle was not altered by supplementation (P>0.05). There was no significant effect (P>0.05) for fat thickness, serum triglycerides, total cholesterol, HDL and LDL between control and copper supplementation regardless of the source. The copper supplementation altered the fatty acid profile of the meat (P<0.05), with an increase in the proportion of lauric acid (C12: 0) in the control group compared with the other treatments (P<0.05). Copper supplementation reduced cholesterol concentration in m. longissimus (P<0.05) in supplemented lambs compared to the control group, this reduction was accompanied by reduction concentrations of GSH (P<0.05) and increasing of oxidized glutathione (GSSG) in the liver (P<0.05). There was no effect of Cu supplementation for TBARS in the liver however, there was significant effect on m. longissimus collected during sawing (P<0.10). There was no effect of Cu supplementation for TBARS in the m. longissimus exposed in the "Display Life after 12 months vacuum freezing (P>0.05), but there was a linear increase in TBARS values during this period. Cu supplementation increased the activity of SOD and GP-x (P<0.05) in the liver. These results suggest that copper can be used to improve meat quality without affecting the oxidative stability.
