ABSTRACT Cadmium (Cd) as cadmium chloride was added to the basal diet of 8-week-old swine at levels of 0, 50, 150, 450 and 1350 ppm for a 6-week comparison period. Growth rate was decreased as a function of Cd level, having ceased in the 1350 ppm group. Hematocrit values were the most sensitive measurement of toxicity and were decreased in all Cd-fed animals. Serum phosphorus was decreased in animals receiving 450 and 1350 ppm Cd, while serum calcium was not affected by Cd intake. Bone ash content was decreased as a function of Cd intake. Leucine aminopeptidase (LAP) activity was depressed in renal cortex from the groups receiving 150 ppm Cd or more, but serum LAP was unaffected by Cd intake. The kidney, liver, spleen and teeth contained the highest concentrations of Cd. Kidney Cd increased with dietary Cd level but appeared to reach a near maximal level in the 450 and 1350 ppm Cd groups. This renal Cd content was directly related to the level of cadmium-binding protein isolated from kidney cortex by gel filtration chromatography. 30 references, 2 figures, 6 tables.

    ABSTRACT: The chemical composition of wild boar meat from wild boar parks with various habitats and different feeding facilities was analysed. Samples were collected from m. serratus anterior – during the winter hunting period. The protein, the total fat, the saturated and unsaturated fatty acid content were measured and also and those elements which have great importance on human alimentation. The results were compared with other author's data of the same parameters of pork. The aim of the study was to compare the effect of different feeding systems on the ingredients of wild boar meat, and the accidental analogy with the ingredients of pork. There was no difference in protein content. The value of miristic acid (C14:0) in the samples of extensively and intensively fed group was more favourable than that of pork. Pork contains more MUFA (palmitoleic acid – C16:1). The semi-intensively fed wild boar's meat and pork contained linoleic acid (C18:3 n3) almost on the same level. The greatest difference was detected in the level of arachidonic acid (C20:4 n6). The samples from all wild boar groups contained more of this fatty acid than it was published about domestic pigs. Out of the microelements, the iodine and zinc had higher value in wild boar meat than in pork.

    ABSTRACT: 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, DurocLandraceYorkshine, 27.671.33 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
