“…The range of iodine content in commercial cat foods varies by a factor of 30, with the largest variation being found in canned cat food (Ranz et al, 2002;Mumma et al, 1986;Johnson et al, 1992;Edinboro et al, 2013). Studies suggest that there is huge variability in the concentration of iodine in commercial cat foods because of the variability of iodine content of individual ingredients.…”

“…In euthyroid humans receiving high levels of dietary iodine, plasma T 4 and T 3 were decreased only slightly, with a compensatory increase in TSH value (Farwell and Braverman 2001); which suggest subclinical hypothyroidism. But studies in cats have incriminated excess dietary iodine as an important factor in the development of hyperthyroid (Tarttelin and Ford 1994;Ranz et al 2002). From the above, it would appear that the effect of excess dietary iodine intake is dependent on the animal species, just as has been observed for iodine requirements for animals (EFSA 2005).…”

Effect of iodine supplementation on thyroid and testicular morphology and function in euthyroid rats

Seventy-five male weaner euthyroid rats, randomly divided into three equal groups were used to evaluate the effect of iodine supplementation in the diet on growth and spermatogenesis. From the age of six weeks, the rat groups were fed normal diet containing 0.05 mg iodine/Kg diet (A); normal diet supplemented with 0.5 mg/Kg iodine (B) and normal diet supplemented with 3.0 mg/Kg iodine for a period of 90 days. Thereafter, all three groups were fed the normal diet for another 60 days. Body weight and feed consumption were determined; morphomeric studies of thyroid glands, testes and epididymes were carried out. Spermatogenesis was evaluated with epididymal (ESC) and testicular sperm counts (TSC). Increasing iodine intake significantly (p < 0.05) decreased mean body weight from day 30 of supplementation. Iodine supplementation influenced feed conversion ratio and efficiency in feed utilization in an inconsistent pattern. Supplementation did not significantly (p > 0.05) alter the size of thyroid glands, but increased the mean weights of the testes and epididymes to levels significantly (p < 0.05) higher than values for non-supplemented rats at specific stages of the study, especially at the highest (3 ppm) level of iodine supplementation. However, supplementation resulted generally in lower sperm counts, which was significant (p < 0.05) in the case of the epididymes. The results of the study show that iodine supplementation to weaner, non-iodine deficient euthyroid rats at 3ppm not only retard weight gain but could also reduce fertility by lowering epididymal sperm counts.

“…No presente estudo, em que foram avaliadas dietas secas e úmidas para gatos adultos, nenhuma amostra continha iodo em níveis menores que os sugeridos para gatos pelo NRC (2006) e os valores obtidos ficaram dentro dos limites relatados por Mumma et al (1986) (0,27 a 5,9 mg/kg/MS) e Johnson et al (1992) tanto em rações úmidas (menos de 0,09 mg/kg a 10,45 mg/kg) quanto secas (1,26 mg/kg a 1,75 mg/kg), bem como nos limites encontrados por Ranz et al (2002), cujas concentrações variaram de 0,22 a 6,4 mg de iodo/kg de ração úmida e 0,47 a 3,2 mg de iodo/kg na ração seca.…”

ResumoObjetivou-se avaliar os teores de iodo em dietas comerciais secas e úmidas para gatos adultos, comercializadas na cidade do Rio de Janeiro. Em 29 amostras, sendo 16 rações secas e 13 úmidas de diferentes sabores os teores de iodo variaram entre 2,7 e 3,4 (média 2,95 mg/kg/MS) nas rações secas e de 2,9 a 4,0 (média 3,4 mg/kg/MS) nas rações úmidas. Das amostras analisadas oito (27,6%) especificavam na embalagem o nível máximo de iodo, sendo uma seca (2,0 mg/kg da dieta) e sete úmidas (0,04mg/kg da dieta). Todas as amostras analisadas apresentaram teores de iodo acima dos valores especificados nas embalagens. Dos teores de iodo analisados, provavelmente os gatos alimentados com dietas comerciais úmidas consomem proporcionalmente mais iodo que gatos alimentados com dietas secas, embora ambas com níveis elevados de iodo. Palavras-chave: Iodo, ração, alimentação, nutrição, gatos AbstractWere analyzed 29 samples, 16 wet and 13 dry cat food of different flavors. The iodine levels ranged from 2.7 to 3.4 (average 2.95 mg/kg/MS) in dry food and 2.9 to 4.0 (average 3.4 mg/kg/MS) in the wet food. Eight samples (27.6%) specified on the package the assurance level (maximum) of iodine, with a dry (2.0 mg/kg/diet) and seven wet (0.04 mg/kg/diet). All non-compliant, because the values were higher than declared. Cats fed commercial diets consume proportionally more iodine in wet food than cats fed dry diets, but both with high levels of iodine. All samples analyzed were above the amounts stated on the labels. Accordingly, the wet and dry commercial food for cats show no reliable values with those reported, resulting in a possible excessive intake of this trace element for animals in question.
