“…The Cu concentration in healthy pigs is ~1.1 ppm (parts per million) (Drouliscos, Bowland and Elliot 1970; Schultze, Elvehjem and Hart 1936), which agrees with the data we extracted through ASV and ICP-OES. More studies are required to validate these new methods, including reproducibility studies.…”

Whole blood is a complex mixture of biological and chemical species. Its pretreatment, which is often conducted by dry ashing, is needed before the analyses of trace metals in whole blood. Recently photo-Fenton Advanced Oxidation Process (AOP) process has been used in the pretreatment of whole blood. Two new AOP processes using simple heating and microwave irradiation have been developed in the current work to pretreat blood samples. The treatments are based on a Fenton-like AOP with acid deactivation of the enzyme catalase. The first treatment is performed with a lab oven over 5 h, while the second uses microwave irradiation for 6 min. These methods allow for either cost-effective pretreatment through the use of the lab oven, or time savings through the use of the microwave oven. The degradations of blood and pure hemoglobin samples are compared through UV/visible spectroscopy, and the copper concentration in the treated samples were analyzed via anodic stripping voltammetry as a demonstration of analyzing trace metals in the pretreated whole blood.

“…Copper is used as feed additive in some countries (up to 250 mg Cu per kg feed) in order t o improve growth performances. Cu-values between 643 and 1575 mg were reported in pig faeces o r pig slurry by some authors (Drouliscos et al, 1970;Gracy et al, 1976). Holland et al, 1975) and should not limit solids in ruminant nutrition.…”

Flachowsky, G., Richter, G. H. and Lohnert, H.J. 1995. Composition and in sacco degradability of variously treated pig slurry solids before and after anaerobic digestion. J. Appl. Anim. Res., 7 : 161-168.The fresh and digested pig slurry was separated into a solid and liquid phase by centrifugation. The solids of the slurry (fresh and digested) were treated with urea andlor NaOH and used for the estimation of chemical composition and dry matter degradability (DMD). Anaerobic digestion did not significantly influence chemical composition except iron content. The DMD of anaerobicallydigested solids was significantly lower (34.8%) than that of the influent material (48%). Chemical treatment of solids from the influent increased DMD from 48.0 to 54.5 (2% urea), 60.2 (2% NaOH) and 62.0% (2% urea and NaOH each); DMD of effluent was increased from 34.8 to 46.4, 49.4 and 51.3%, respectively. Pig slurry solids from the effluent of anaerobic digesters contain low energy for ruminants and should primarily be used as manure.

“…These results agree with those for pigs as regards food intake and rate of gain, but with pigs, food conversion is usually more efficient in females (Elliot and Bowland 1968, l97O Underwood (1962) noted that the rat maintains a low liver copper level in spite of a relatively high absorption of copper from the diet. Pigs fed identical diets to those used in the present study displayed increased liver copper levels (Drouliscos et al 1970 (Table 3).…”
