“…The addition of copper sulphate (up to 250 ppm) to pig diets improves growth performance and increases serum copper concentration (3,18,29). Copper is believed to stimulate growth performance due to its bacteriostatic properties (15).…”

“…Carrier status frequently occurs in poultry and pigs, with special reference to industrial breeding and production plants (6). In particular, swine can often carry Salmonella in both the intestinal tract and the mesenteric lymph nodes (15). Modern slaughter procedures potentially involve many risks of both direct and cross-contamination of carcasses and meat surfaces.…”

SUMMARYIn a cohort study, 40 pig finishing herds were selected twenty pig herds with a low and twenty pig herds with a high prevalence of several pathological lesions recorded at slaughter in a six-month period before the start of the study. Blood samples were taken from 20 pigs per herd at the end of the finishing period to investigate haematological and clinicochemical profiles. There was only a significant difference in serum albumin concentration between the low and high lesion prevalence groups. There were distinct differences in blood profiles between pig herds, but also between batches of pigs within a herd housed in different compartments. Differences between castrated males and gilts were also demonstrated with respect to mean values of the blood variables haemoglobin, iron, copper,fl-globulin, eosinophils and segmented neutrophils. However, the differences were not of a biologically important magnitude. The mean values of the blood variables pepsinogen and lymphocytes differed significantly between pig herds from the two participating integration groups.

Hawbaker et al (1961) The mechanism by which the addition of copper to diets affects the performance of growing pigs is poorly understood, although it has been suggested that the action is bactericidal or perhaps anthelmintic in nature (Hawbaker et al 1961 Castell and Bowland (1968b …”

This study was conducted to investigate the effects of dietary supplementation of Cu-sulfate, Cu-methionine chelate (Cu-Met) and Cu-soy proteinate (Cu-SP) on the performance, blood parameters and mineral contents of muscle. It was conducted with a total of 1,000 one d old broilers chickens (Ross Ⓡ ) which were assigned to four dietary treatments; Control, Cu sulfate (200 ppm Cu as CuSO4․5H2O), Cu-Met (200 ppm Cu as Cu-methionine chelate), Cu-SP (200 ppm Cu as Cu-soy proteinate). There were significant differences (p<0.05) among treatments in weight gain. Weight gain of Cu treated groups were higher than the control during 3～5 wk. There were significant differences (p<0.05) among treatments in feed intake during 0～3 wk. Cu-Met was significantly (p<0.05) lower than the control but the differences among Cu treatments were not significant. There were significant differences (p<0.05) among treatments in feed conversion rate (FCR). Cu treated groups were lower than the control during the whole period. Production efficiency factor (PEF) was significantly higher (p<0.01) in Cu treated groups than the control. Nutrient availabilities of diets were not significantly different among the treatments. The count of white blood cell (WBC) and eosinophil (EO) were lower in Cu-SP treatment than in the control. Copper concentration in the liver was significantly (p<0.01) higher in Cu treated groups than the control. Zinc concentration in the breast and wing muscle was lower in Cu treated and that of leg muscle was higher in Cu-Met than the control. The result of this experiment showed that Cu supplementation at the level of 200 ppm as Cu sulfate, Cu-Met and Cu-SP improves weight gain (4～5 wk), FCR and PEF. Differences among Cu sources were not significant.
