Effect of Using Different Heat Treatments Grass Pea Seed Lathyrus sativa of Secretion on Some Digestion Enzymes of Small Common Carp Cyprinus carpio L.

Abstract

AbstractThis study was carried out in the laboratories of Fish and Animal ResourceCenter/Agricultural Researchers Directorate/Technology and Science Ministry to study theexcretion of some digestible enzymes for amylase and protease under the effected the ofheat treatments and substitute ratio forGrass Pea Seeds Lathyrus sativa (GPS) in commoncarp Cyprinus carpio L. diets. The experiments of nutrition and digestion were done for 80days using three different treatments for GPS, roasting, autoclave and cooking. Formulated13 experimental diets were done as the following diets 1, 2 and 3 used GPS withouttreatment at ratio 8.25%, 16.75% and 25% from total diet and substitute ratio 33%, 66%and 100% from Soy Bean Meal (SBM), the diets 4, 5 and 6 used roasted GPS at the sameratio and substitute as above. The diets 7, 8 and 9 used cooked GPS at the same ratio andsubstitute as above and diet 13 for control without GPS. There is a significant difference ofdigestive enzyme in all studied parts of digestive tract, between after 5-days and 80-daysfeeding. The activities were (0.45, 0.544, 0.454, 0.454, 0.455 U/M) for amylase and (1.47,1.49, 1.49, 1.46 and 1.46 U/M) for protease, respectively. The activities of above enzymeafter 80 – days feeding trial revealed no significant differences between types of alltreatments and the control diets.Keyword:Lathyrus sativa, Cyprinus carpio Ant nutritional Factor.
