Abstract

Two types of fodder crops were evaluated in this study, maize (Zia maize) and black gram (BG) (Vigna mungo) and in maize, non-descriptive local maize (LM) and hybrid maize (HM) verity were used. LM was considered as control and changes of the nutritional composition according to the type of fodder (leguminous and non-leguminous) and the day was evaluated. For comparative nutritional analysis, dry matter (DM), crude protein (CP), ether extract (EE), crude fibre (CF), acid detergent fibre (ADF), neutral detergent fibre (NDF), and total ash were analyzed and the biomass yield was measured using weight balance and root and shoot length of experimental fodders. Results revealed that among three types of forages total DM was significantly (P<0.01) higher in HM and significantly (P<0.01) lower in BG. Considering total CP and NDF, it was significantly (P<0.01) higher in BG and HM than LM. The highest biomass yield and shoot length were observed in BG and the lowest biomass yield was observed in HM. Moreover, with the increment of days, all fodder sprouts DM% was constantly decreasing, however, CP% maintained the same level from day 1 to 5. Although from day 6 to 9, CP% increased moderately for HM and BG, CP% decreased slightly for LM. Therefore, farmer can use BG and HM for maximum utilization of nutrients and considering DM and CP% for LM day 6 was the best time for harvesting; however, for HM and BG, day 9 or more than 9 was the best time for harvesting. Res.

Summary

Introduction

Green fodder is a prerequisite; many reasons are hindering green fodder production. Different types of grain such asmaize (Zea mays), oats (Avena Sativa), barley (Hordeum Vulgare), wheat (Triticumae stivum), alfalfa (Medicago sativa), cowpea (Vigna unguiculata), sorghum (Sorghum bicolor), black gram (Vigna mungo L.) seed can be used for hydroponic fodder production (Masood et al, 2014; Rachel et al, 2018; Ghazi et al, 2012) This technology has a 6-7 times higher biomass conversion ratio compared to conventional green fodder production, along with enabling bioactive enzymes, essential fatty acids and minerals by converting complex nutrients into a simple component which is essential for animal growth and proliferation (Naik et al, 2015). Hydroponic is a highly profitable technique for fodder production in some particular areas of Bangladesh (Uddin and Dhar, 2018)
