Effect of Alfalfa Medicago sativa and Apricot kernel Prunus armeniaca extracts on growth performance survival rate enzymatic activity and body composition of common Carp Cyprinus carpio communis Linnaeus 1758

Abstract

The primary requisite for a successful and sustainable aquaculture setup is to provide the optimum level of dietary macro- and micro-nutrients for maintaining disease free rearing units. This study focused on determining the optimum protein requirement and evaluating the possible use of alfalfa and apricot kernel extracts as feed additives in fingerlings of common carp. Fish with equal mean weight were randomly distributed in different treatment groups and fed with experimental diets containing varying amounts of protein and plant extracts. The results at the end of the feeding trials revealed that when fed on 38% of the dietary protein together with an enhanced dosage of dietary alfalfa and apricot kernel extract supplements, fish displayed improved growth and health as evidenced by increased feed utilization efficiency, enhanced digestive enzyme activity, improved gut histomorphometry and disease resistance. In conclusion, the present study strongly indicates that the alfalfa and apricot kernel extract has anti-oxidant and immune-enhancing potential which might be very helpful in improving growth and combating bacterial infections in fish. newline
