Effect of Cadmium in Feed on Organs and Meat Colour of Growing Pigs

Abstract

One hundred and ninety-two barrows (Duroc x Landrace x Yorkshire, initial weight 27.7 kg) were used to investigate the effects of cadmium in feed on the function of selected organs and meat colour of growing pigs. The pigs were randomly allocated into four different treatments. Each treatment included three replications with 16 pigs per replicate. The animals were fed corn-soybean basal diet and supplemented with 0, 0.5, 5.0, 10.0 mg/kg cadmium (as CdCl(2)), respectively. The feeding trial ended when the average body weight of the pigs reach 90 kg. The results showed that, compared with controls, addition of 10 mg/kg cadmium to the diet resulted in significant elevations of relative weight of liver and spleen by 18.3% (p<0.05) and 19.7% (p<0.05) respectively, and of serum glutamic-pyruvic transaminase (GPT) and glutamic-oxaloacetic transaminase (GOT) activities by 17.8% (p<0.05) and 27.4% (p<0.05) respectively; and significant decreases of Na(+)/K(+)-ATPase activity in the liver by 24.6% (p<0.05), the redness of longissimus dorsi by 26.6% (p<0.05) and 24.9% (p<0.05) at 0.75 h and 16 h post mortem, respectively, and of the myoglobin content of longissimus dorsi by 19.4% (p<0.05). No changes were found in these indices above when the pigs were fed the diet supplied with 0.5 or 5 mg/kg cadmium (p>0.05), nor in renal functions among cadmium-treatment treatments (p>0.05) as indicated is the activities of urinary N-acetyl-beta-D-glucosaminidase (NAG) and alkaline phosphatase (ALP) and the content of urinary protein. The study indicated the adverse effects of 10 mg/kg cadmium in feed on liver functions and meat colour of growing pigs.

Alteration in the activity of oxidative enzymes in the tissues of male wistar albino rats exposed to cadmium

“…Horiguchi et al [16] observed hepatosplenomegaly and kidney swelling after subcutaneous administration of Cd in rats. Similarly, a Cd-induced increase in liver and spleen weight has also been observed by Tu et al [28].…”

Sorption of tetracycline to sediments and soils: assessing the roles of pH, the presence of cadmium and properties of sediments and soils

“…Cadmium (Cd), a nonessential element, can have various adverse effects on animals and humans because of its accumulation in the environment through the use of animal manures, phosphorus fertilizers, sewage sludge, or atmospheric deposition [19,20]. A high content of Cd may be present in livestock additives because of contamination of mineral supplements (e.g., some limestone added to laying hen feeds), which is excreted without any metabolization [21].…”

Survey Detection of Trace Heavy Metals in Potato Chips and Ice Cream From Assiut Governorate, Egypt

“…The cadmium concentrations in potato may be due to the soil in which the potato was grown (Bahemuka & Mubofu, 1999). In ice cream, a recent study suggested that the main inputs of cadmium to animal feed in farmed animals are feeding crops, trace element premixes, fish meal, and minerals such as, limestone and phosphate (Tu et al, 2007;Bilandzˇic´ et al, 2011 ).…”
