“…Similar results were observed in the study of Chmielnicka et al (1996). On the other hand, studies indicated that increased copper supplemented in feed could promote retention of cadmium in tissues of swine (Rambeck et al, 1991;Rothe et al, 1994). In their experiment, weanling pigs received for 3 months a diet containing 1 mg/kg cadmium, as well as 0, 50, 100 or 200 mg/kg copper.…”

This experiment was conducted to investigate the effect of cadmium levels on weight gain, nutrient digestibility and the retention of iron, copper and zinc in tissues of growing pigs. A total of one hundred and ninety-two crossbred pigs (barrows, Duroc×Landrace×Yorkshine, 27.67±1.33 kg of average initial body weight) were randomly allotted to four treatments. Each treatment had three replicates with 16 pigs per pen. The corn-soybean basal diets were supplemented with 0, 0.5, 5.0, 10.0 mg/kg cadmium respectively, and the feeding experiment lasted for eight-three days. Cadmium chloride was used as cadmium source. The results showed that pigs fed the diet containing 10.0 mg/kg cadmium had lower ADG and FCR than any other treatments (p<0.05). Apparent digestibility of protein in 10.0 mg/kg cadmium-treated group was lower than that of other groups (p<0.05). There was lower iron retention in some tissues of 5.0 mg/kg and 10.0 mg/kg cadmium treatments (p<0.05). However, pigs fed the diet 10.0 mg/kg cadmium had higher copper content in most tissues than that of any other groups (p<0.05). There was a significantly increase of zinc retention in kidney of 10.0 mg/kg cadmium additional group (p<0.05) and zinc concentrations in lymphaden, pancreas and heart of 10.0 mg/kg cadmium treatment were lower than those of the control (p<0.05). This study indicated that relatively high cadmium level (10.0 mg/kg) could decrease pig growth performance and change the retention of iron, copper and zinc in most tissues during extended cadmium exposure period.

“…Cadmium contamination levels seem to be very low in Galicia (Caridad-Cancela et al, 2005) (EFSA, 2004a) are similar for ruminants (mean 11, range 0.03-0.85 mg/kg dry matter) and pigs (means for different ages 0.07-0.16, range 0.01-0.50 mg/kg dry matter). It is possible that the higher cadmium levels in pigs could be related in part to the widespread practice in intensive production systems of giving copper and zinc supplements (Rambeck et al, 1991). Experimental studies have demonstrated that in pigs receiving a conventional intensive diet, cadmium concentrations in the liver and kidney were twice as high as in animals that received high copper supplements (Rothe et al, 1992) compared to the control animals.…”

“…The European Commission has established maximum admissible levels for cadmium in liver, kidney and muscle of 0.5, 1 and 0.050 mg/kg fresh weight respectively (European Commission, 2001); none of the pigs sampled in this study exceeded these levels in any of the tissues analysed. Although cadmium accumulation rates are high in pigs compared to other livestock, especially when receiving copper supplementation (Rambeck et al, 1991), the fact that these animals are slaughtered very young generally means that cadmium levels in offal do not exceed the maximum limits.…”

The aims of the study were to evaluate toxic and essential metal concentrations in meat and offal from pigs in north-west Spain to compare these with reported metal concentrations in pigs in other countries and in cattle in this region, and to relate the observed concentrations to maximum acceptable concentrations. Samples from 63 pigs aged 6 months were randomly collected at slaughter. After acid digestion, levels of metals were determined by ICP-OES and ICP-MS. As regards the toxic metals, mean concentrations in liver, kidney and muscle were 0.073, 0.308 and 0.009 mg kg(-1) fresh weight for cadmium, 0.004, 0.008 and 0.003 mg kg(-1) for lead, 0.013, 0.011 and 0.003 mg kg(-1) for arsenic, and 0.001, 0.002 and 0.001 mg kg(-1) for mercury. These concentrations can be considered low, and in general similar to those reported in similar studies in recent years. In addition, maximum admissible concentrations established by the European Union were not exceeded in any sample. As regards the essential metals, concentrations in liver, kidney and muscle were 14.9, 5.63 and 6.85 mg kg(-1) for copper, 81.3, 28.9 and 42.5 mg kg(-1) for zinc, 195, 51.6 and 26.5 mg kg(-1) for iron; 1.17, 2.51 and 0.656 mg kg(-1) for selenium, 3.32, 1.56 and 1.01 mg kg(-1) for manganese, 0.023, 0.027 and 0.003 mg kg(-1) for cobalt, 0.120, 0.077 and 0.131 mg kg(-1) for chromium, 0.009, 0.027 and 0.026 mg kg(-1) for nickel, and 1.62, 0.683 and 0.140 mg kg(-1) for molybdenum. These concentrations are all within the accepted adequate-safe ranges for this animal species, and in general are in line with those previously reported in the literature.

Der Einfluß von Vitamin C und Zink auf die durch Kupfer erhöhte Rückstandsbildung von Cadmium beim Schwein

In commercial pig fattening, copper is added to the feed in amounts that greatly exceed the requirements of the animals. On the one hand, this improves weight gain, but on the other, as we were able to recently prove, the retention of the heavy metal cadmium rises in the kidney, in the liver and in muscle. In a feeding experiment with female and male castrated piglets, we tried to counter the copper-induced rise in cadmium (175 mg Cu/kg feed) by adding zinc or vitamin C to the diet. While addition of 100 or 200 mg zinc per kg of diet had no influence, the addition of 1000 mg vitamin C reduced the elevated cadmium values in the kidneys and livers to values only determined with a low copper supplementation of 35 mg copper per kg of feed. This positive vitamin C effect not only occurs in cases of high copper supplementation (175 mg Cu/kg feed); when the pigs were given only 35 mg copper per kg of feed, vitamin C also reduced the cadmium content in the organs by 35 to 40%. This indicates that vitamin C improves the quality of food gained from animals for human consumption in both conditions.
