Nutritional evaluation of commercial dry dog foods available on the Czech market
Popis výsledku v původním jazyce
The evaluation of the quality of commercial diets is a topic of interest to dog owners and veterinarians. The aims of the study were to determine proximate analysis, metabolizable energy and some amino acids in dry dog diets for different ages, divided into three groups G1 (low price, grains included), G2 (medium price, grains included) and G3 (high price, grain-free). The hypothesis was tested that there are significant differences in the analysed values between dry dog diets from different price categories and between grain-free and grain-containing diets. Furthermore, the analysed values were compared with AAFCO and FEDIAF recommendations and with label values guaranteed by manufacturers to see whether there are any deviations. We analysed 60 samples of complete dry dog diets purchased in the Czech Republic, using the standard AOAC methods of proximate analysis. Metabolizable energy was calculated using the NRC equation, and 30 samples were analysed for selected amino acids. The results showed that there are significant differences in protein and amino acid contents between grain-free (G3) and grain-containing (G1,2) dog diets. G3 diets had significantly (p < 0.01) higher crude protein and essential amino acid contents. No significant differences were found between grain-containing diets G1 and G2. The results may indicate a higher proportion of animal components and a lower content of carbohydrates in G3 diets. Most of the tested dog diets met the AAFCO and FEDIAF recommendations. There were only a few deviations in threonine in G1 and G2 diets for growing dogs.
