Abstract
This study investigated by the aim of 60 percent guar crumpled replacement by soy from 345 number of fry Onchorhynchus mykiss Growth and survival indexes by mean weight (82±2 gr) in 5 doze and three replicated (0,25,50,75 and100%) equal to(0,3.88,7.8,11.63 and 15.5% guar crumpled as an protein equivalent within same amount of energy and proteins of diet. Biometries have done from five samples of each treatment once fifteen days till 60 days of study. At The End of test by meager and calculated of final and, increasing weight, amount of diet as fed , food concentration ratio(FCR),special growth rate(SGR) ,protein efficiency ratio (PER) , condition of fattening(CF) and survival rate(SR) results showed; there is significant difference for all growth index except initial weight by replacing guar crumpled in the diet (P>0.05). There is high significant difference in amount of diet as fed, weight increasing and survival rates between treatments brightly (P<0.01). So on, to achieve the useful providing efficiency by the suitable process guar crumpled had less amount of anti feeding effects and could be replaced by soy crumpled as a herbal protein resource.
