Abstract

كان استخدام النباتات المائية المجففة كبروتين يومي للحيوان والأسماك موضوع البحث في هذه الدراسة. تحليلات لنباتات مختلفة (صفير الماء ، طحلب البط ، اللوتس) في المختبر. هذا لتقييم إمكاناتها في تكوين الحيوانات والأعلاف. أظهر التحليل التقريبي أن المحتوى الرطوبي تراوح من 6.25٪ في النبات إلى 32.5٪ للدهون الخام ، وأقل قيمة من 2.5 إلى 5.4 في النبات بأكمله ، بينما تراوحت نسبة الألياف الخام من 4.5 إلى 11.1٪ في كامل النبات. تراوحت نسبة البروتين الخام من 8.55٪ إلى 14.2٪. في نبات الطحلب البطي بكامله ، يمكن استخدام النبات المفضل كمصدر غذائي لتغذية الحيوانات والأسماك ثم صفير الماء واللوتس. إجمالي الأحماض الأمينية كمية كبيرة في ماء صفير من اللوتس والطحلب (397.638 ، 175.98 و 95.915 مجم / جم).

Highlights

Aquatic plants grow copiously in different aquatic bodies such as lakes and waterways all around the world (Muhammed et al, 2012)
Considerable attention has been devoted to the replacement of fish meal with plant protein sources such as soy-bean meal (Oliva-Teles et al, 1994); Refstie et al, 1998), mucuna seed meal (Siddhuraju and Becker, 2001) Globally, the food research emphasis on the production of high quality food and feeds of plant origin as the green plants are recognized as excellent source of protein, fats and pharmacological active and secondary metabolism
For example, stems and rhizomes as fresh vegetables; seeds as dessert and medicine; flowers as religious ornaments, and several parts as raw materials to produce cosmetics (Yi et al, 2002).To enhance the full utilization of those weed, the evaluation of its nutritive value in this study has the objectives to evaluate based on its nutritive value, its potentials in fish feed and animal feed of the various plants

Summary

Introduction

Aquatic plants grow copiously in different aquatic bodies such as lakes and waterways all around the world (Muhammed et al, 2012). Compared with most other plants, duckweed leaves contain little fiber percentage of (5% in dry matter for cultivated plants) and little to almost zero indigestible material even for mono gastric animals (Chaturvedi et al, 2003) This contrasts with the compositions of many crops such as soy beans, rice, and maize, approximately 50% of whose biomass comprises residues high in fiber and low in digestibility. For example, stems and rhizomes as fresh vegetables; seeds as dessert and medicine; flowers as religious ornaments, and several parts as raw materials to produce cosmetics (Yi et al, 2002).To enhance the full utilization of those weed, the evaluation of its nutritive value in this study has the objectives to evaluate based on its nutritive value, its potentials in fish feed and animal feed of the various plants (water hyacinth ,duckweed and lotus)
