Effect of Eucommia Ulmoides Oliver on Meat Quality and Activities of SOD and Lysozyme to Allogyogenetics Silver Crucian Carp

An experiment was conducted to investigated the effect of adding Eucommia ulmoides Oliver on meat quality and non-specific immune function of allogyogenetics silver crucian carp.The fishes with body weight of 115.8±5g were fed with basal diet without(control group) or with adding 1% skin powder,leaves powder and skin extract for 60 days.Results showed that(1) The water loss rate and the myofibrillae lengthes of the four groups were 25.17%、21.77%、26.57%、17.80% and 28.81 mm、36.57 mm、34.22 mm、30.76 mm respectively.The hydroxyproline were 0.132 mg/g、0.222 mg/g、0.168 mg/g、0.185 mg/g.The water loss rate and the hydroxyproline were significantly improved by adding 1% skin powder and skin extract,the myofibrillae lengthes were significantly improved by adding 1% skin powder and leaves powder.(2) About non-specific immune index,serum SOD activities were significantly improved by adding leaves powder and skin extract,but lysozyme activities were not affected.Results above showed that,meat quality and serum SOD of allogyogenetics silver crucian carp could be improved by adding Eucommia ulmoides in diets.
