Özet

In this study, the proximate composition and some amino acid profiles of the marsh frog (66.54 +/- 6.75 g) grown using marsh frogs (Pelophylax ridibundus) collected from nature (62,613 +/- 15,86 g) and the pellet food containing 35% crude protein were examined in this study. This study has been carried out on female frogs, particularly for the fact that in the same age female ones weigh more than their male counterparts. As a result of the study, it was determined that the amount of crude protein in the leg meat of the female cultured frogs was higher than that of the female wild frogs and that these values are 19.69 +/- 0.17 g / 100 g and 18.88 +/- 0.48 g / 100 g without a statistically significant difference (P> 0.05) between them.

As a result of the study, it was determined that the amount of crude protein in the leg meat of the female cultured frogs was higher than that of the female wild frogs and that these values are 19.69 +/- 0.17 g / 100 g and 18.88 +/- 0.48 g / 100 g without a statistically significant difference (P> 0.05) between them. 

It was evaluated that the amount of fat in female frogs raised in the farm was 0.71 +/- 0.03 g and that of the wild frogs was 0.82 +/- 0.03 g and that the difference between these amounts was not significant (P> 0.05). Sixteen amino acid analyses indicated that the amount of amino acids in the female frogs cultivated was higher than in the wild and it was determined that the difference between the amounts of amino acids other than isoleucine, leucine, valine and alanine was significant (P <0.05). The high amounts of lysine, glutamic acid, aspartic acid and leucine were respectively detected in the meat of female frogs, both from the nature and from farms. Of these sixteen amino acids, while nine are essential amino acids (lysine, histidine, arginine, threonine, valine, methionine, isoleucine, leucine and phenylalanine), lysine has been identified as the essential amino acid with the highest concentration in female frogs found both in nature and in farms. As a result, it has been determined that P. ridibundus is a worthwhile crop and a rich source of nutrients for humans.
