The present study aimed to compare the composition on the label of dry complete food for adult cats with the nutritional composition determined by chemical analysis, to determine the occurrence of aflatoxins, and to list the most used ingredients. The determined parameters were: crude protein (CP), ether extract in acid hydrolysis (EEA), mineral matter (MM), moisture (MO), crude fiber (CF), calcium (Ca), phosphorus (P), sodium (Na), calculated metabolizable energy (ME) and aflatoxins. In assessing the levels guaranteed on the label, MO, CP, CF, MM and P remained within the range, but with a variation on the limits. The metabolizable energy varied from 3,712 to 4,136 kcal/kg. There was a divergence in the levels of two diets, with Ca above and EE below the values declared on the label in relation to composition obtained by chemical analysis, and both non-compliant in 20% foods tested. Regarding sodium, the diets showed levels 130 -384% higher than stated on the label. Aflatoxin was found in 90% samples from zero to 4.37 ppb. The wide variation observed in the composition within the same super premium segment can cause losses due to the lack or excess of essential nutrients for the animal.
O objetivo do trabalho foi definir as necessidades nutricionais de cães machos reprodutores através de publicações científicas e, a partir destas, verificar alimentos completos e suplementos comerciais que atendam essa categoria. Foram identificadas oito publicações com 124 cães avaliados. Os nutrientes avaliados foram: Vitamina E, Selênio, Ômega 3 e Ômega 6. Os parâmetros usuais na avaliação de qualidade de sêmen foram: volume; motilidade, vigor espermático e concentração espermática. O estudo mostrou que o ideal para cães machos reprodutores será seguir as tabelas oficiais de exigências nutricionais, uma dieta com: 3.750 kcal/kg; proteína bruta de 24%; Cálcio de 1,113%; Fósforo de 0,905%; Selênio de 0,408%; Vitamina E de 40 mg/kg e Ômegas 3 e 6 de 5500 e 300 mg, respectivamente. Para suplementação, além das exigências nutricionais, recomenda-se: Vitamina E: 50 mg/kg; Selênio: 0,60 mg/kg; Ômega 3: 7,2 mg/kg; Ômega 6: 25 mg/kg de peso corporal durante média de 60 dias. Foram encontrados cinco alimentos completos comerciais que atendem as necessidades. Os alimentos necessitam de suplementação. Foram identificados três suplementos que atenderam, as recomendações estimadas.
