MCQ (Single Correct) +3 −1

Quality of dry fodder can be improved by treatment of :

सूखे चारे (पुआल / कड़बी) की गुणवत्ता किसके उपचार द्वारा सुधारी जा सकती है ?

Common salt साधारण नमक के उपचार द्वारा Urea यूरिया के उपचार द्वारा Potassium permanganate पोटेशियम परमैंगनेट के उपचार द्वारा DAP डी.ए.पी. के उपचार द्वारा

Urea treatment (urea ammoniation) is a proven, cost-effective technology to improve the nutritive value of poor-quality dry cereal straws (paddy straw, wheat straw, sorghum stover).
Dry straw is treated with a 4% urea solution (4 kg fertilizer-grade urea dissolved in 40-50 liters of water sprayed per 100 kg straw) and sealed airtight under polythene or in a stack for 3 to 4 weeks.
Microbial and urease enzymes hydrolyze urea into ammonia gas ($NH_3$), which breaks ligno-cellulosic bonds, increases straw digestibility by 10-15%, and raises crude protein equivalent from 3% to 7-9%.
Thus, Urea treatment (Option 2) significantly improves the quality of dry fodder.

सूखे चारे (जैसे गेहूँ का भूसा या धान का पुआल) की गुणवत्ता और पौष्टिकता बढ़ाने के लिए 'यूरिया उपचार' (Urea treatment) सबसे प्रभावी एवं प्रचलित विधि है।
इसमें 100 किग्रा सूखे भूसे पर 4 किग्रा यूरिया को 40-50 लीटर पानी में घोलकर समान रूप से छिड़क दिया जाता है तथा 3-4 सप्ताह के लिए ढककर बंद कर दिया जाता है।
उत्पन्न होने वाली अमोनिया गैस लिग्निन-सेल्यूलोज बंधों को तोड़कर चारे की पाचकता बढ़ाती है तथा चारे में कच्चे प्रोटीन की मात्रा 3% से बढ़कर 7-8% हो जाती है।
अतः सूखे चारे की गुणवत्ता यूरिया के उपचार द्वारा सुधारी जा सकती है (विकल्प 2)।
