Selected features of copper metabolism in the cat.

摘要: In separate experiments, domestic short hair kittens were fed diets based on soy or egg white protein containing from 1.98 to 9.64 0.58 9.8 micrograms Cu/g diet, respectively. Moreover, also nursed queens either 12 of diet. each experiment, copper was analyzed in liver, spleen, lung, heart, muscle and brain samples. The liver concentration the most responsive changes dietary intake. For example, weanling 24 45 micrograms/g wet weight, Likewise, levels hepatic Cu,Zn-superoxide dismutase reduced low However, concentrations zinc, iron manganese brain, kidney not consistently changed response intakes. Anemia a consistent feature copper-deficient cat kitten, but signs connective tissue lesions observed born weaned less than 1 Based these observations data for growth differing copper, requirement kitten estimated be 4-5 diet (energy content approximately 5 kcal 21 kJ per gram).
