تأثير إحلال حبوب البيقيا الخام raw common vetch Vicia sativa بديلاً عن كسبة فول الصويا في علائق أسماك الكارب الشائع Cyprinus carpio L.

Abstract EN

This study carried out to evaluate of substitution of soybean meal by raw common vetch seed Vicia sativa L.

.

A total of 96 common carp Cyprinus carpio L.

with average weight 32 ± 2 gm / fish .

had distributed randomly over forth experimental diets with three replication for each diet .

which contain different rates of raw common vetch ; Zero % (Control diet .

diet 1) and three diet contained 15%.

30 % and 45 % of a total diet (2 .

3 and 4) respectively instead of 26 % .

55 % and 80 % of soybean meal .

Statistical analysis of results showed a significant differences (P > 0.05) in weight gain .

growth rate .

relative growth rate .

specific growth rate .

food conversion ratio .

protein efficiency ratio (PER) and protein productive value (PPV) between control diet and fish were fed at diet 3 and 4 .

whereas there were no significant differences were recorded among fish were fed at diet 2 for above criteria except that for protein efficiency ratio .

It will be concluded that possibility of replacing 26 % of soybean meal by common raw vetch (15 % of total diet) without impacting on studied characteristics with concerning growth and food utilization .
