Abstract
This investigation was carried out to utilize common vetch Vicia sativa in formulating diets for 84 common carp Cyprinus carpio L. with initial weight 28±2g/fish were distributed randomly over seven experimental diets with three replications for each. The fish fed experimental diets for 56 days contained 30% and 45% of common vetch Vicia sativa of total diets which treated with germinated for 5 days (diet 2 and 3), 7 days (diet 4 and 5) and the last diets contained crude vetch (diet 6 and 7). The statistical analysis of data showed that the fish fed at diet 3 was significantly different (P≤0.05) compared to fish fed at another diets in total weight, total weight gain, relative growth rate, specific growth rate and feed conversion ratio. It is in conclusion germinated common vetch seed can be successfully used as an inexpensive plant protein source at level of 45% (germinated seed for 5 days) in common carp diets without adverse effect on fish performance.
Highlights
84 common carp Cyprinus carpio L. with initial weight 28±2g/fish distributed randomly over seven experimental diets with three replications for each
This study was designed to determine the potential nutritional value of germinated common vetch Vicia sativa seeds for five and seven days at different levels in spite of soybean meal in diet as plant protein source for common carp Cyprinus carpio L. depending up on the results of Khadom [18] who found a higher reduction in trypsin and phytic acid activity at 7days of germination for both tested seed groups this results indicated that 30% substitution of germinated seeds have no negative effect on growth criteria for common carp fish
Chemical component: Crude protein was increased at the number of days of germination of common vetch (CV) increased to 7 days (Table, 2) and was higher (P≤0.05) than the crude protein content of beans from the control groups
Summary
This investigation was carried out to utilize common vetch Vicia sativa in formulating diets for 84 common carp Cyprinus carpio L. with initial weight 28±2g/fish distributed randomly over seven experimental diets with three replications for each. This study was designed to determine the potential nutritional value of germinated common vetch Vicia sativa seeds for five and seven days at different levels in spite of soybean meal in diet as plant protein source for common carp Cyprinus carpio L. depending up on the results of Khadom [18] who found a higher reduction in trypsin and phytic acid activity at 7days of germination for both tested seed groups this results indicated that 30% substitution of germinated seeds have no negative effect on growth criteria for common carp fish. Fish fed at seven experimental diets which contained crude and germinated common vetch Vicia sativa at levels 30% and 45% instead of 0% (control diet), 55 and 80% of soybean meal for each level of experimental substitution (Table, 1).
