@article{Huque_Roy_Das_2017, title={Biometrical Ranking of Fodder Crops for Sustainable Livestock and Clean Air Production}, volume={5}, url={https://ajouronline.com/index.php/AJAFS/article/view/4868}, abstractNote={The study was conducted with the objectives to develop a professional forage quality ranking scale by considering their efficiency of biomass production (X<sub>ddm</sub>), animal production response (X<sub>ap</sub>), enteric methane emission reduction (X<sub>CH4</sub>) and benefit to cost ratio of their production (X<sub>bc</sub>) in proportion to a typical fodder: maize, considering its constant efficiency of 1.0. Available fodder crops were cultivated following standard agronomical practices and conserved to develop database for calculating X<sub>ddm</sub>, and X<sub>bc</sub>. Considering maize as a control roughage, a series of feeding trials on the native cattle of Bangladesh was conducted to calculate X<sub>ap </sub>andX<sub>CH4</sub>. The maize index (M<sub>i</sub>) of a test fodder crop was calculated as: M<sub>i</sub> =  . The M<sub>i </sub>of Moringafeed was found the highest (1.64), followed by Maize (1.00), Australian sweet jumbo (0.99) and Napier- Bajra (0.82). The German, Napier-Hybrid, Napier Arusha and Andropogon had the M<sub>i</sub> of between 0.80 and 0.50 (0.72, 0.63, 0.57 and 0.50, respectively). Next, the M<sub>i</sub> of Sugargraze jumbo, Splendida, UMS (Aus), and Para fall between 0.49 and 0.40 (0.45, 0.43, 0.42, 0.41 and 0.40, respectively). The least Mi (below 0.40) was found in UMS (Aman), local grass and Plicatulum (0.39, 0.35 and 0.35, respectively). The M<sub>i</sub> of UMS (Aman), local grass and Plicatulum was below 0.40. The M<sub>i</sub> may be used for the ranking of fodder crops for their cost effective production and feeding to animals and help reduction of enteric methane emission in the rumen.}, number={3}, journal={Asian Journal of Agriculture and Food Sciences}, author={Huque, Khan Shahidul and Roy, Biplob Kumer and Das, Nani Gopal}, year={2017}, month={Jun.} }
