| The hydroponic under Egyptian condition take more attention in the last decade. The experiment was conducted under net house in intensive hydroponic system and replicated three times during January and February 2017. The study was done to evaluate vegetative characteristics and quality properties of produced sprouting of six barley cultivars (Giza123,126,127,128,129 and130). The results observed that the sprouting can be produce in 8 days from planting to harvest using hydroponic technique under the net house conditions. The Highest green barley fodder was recorded with Giza 127 followed by 129 which gave 6.98, 6.83 Kg, respectively compared with other strain. The results indicated that the highest value of fresh sprout: seeds weight ratio was recorded significantly by Giza 127 followed by Giza 129 compared to the other four cultivars. The crude protein values in several green fodder barley species significant (P<0.05) increase (the range from 11.56 to 13.45%) compared with its grains (the range from 9.58 to 12.60%). The highest values CP% in green fodder barley recorded with (Giza 127) was (13.45% on DM basis). There were a significantly (P<0.05) increase for CF% between green fodder barley species (the range from 9.93 to 14.36) in 8- days sprouting compared with the several original barley grains (the range from 5.67 to 8.85%). Also, the EE were significant increased except (Giza 129 and Giza 130) were decreased. The highest significant values NDF was recorded (37.47%) with (Giza 123) compared several cultivator Green fodder barley species, but ADF was recorded (17.93) with (Giza 127). The highest significant values ADF and acid insoluble ash were recorded (5.91 and 1.78) with (Giza 130) compared several cultivator Green fodder barley species. The highest significant values hemicellulose was recorded (20.85%) with (Giza 123), celluloses was recorded (12.63%) with (Giza 126) compared several cultivator Green fodder barley species. however, significant increased NDF-cell soluble was recorded (80.88) with (Giza 130). The parameters of nutritive values are predication from chemical composition observed significant increase of DCP between seed barley and several cultivator Green fodder barleys except Giza (129) and (130). The highest result values of DCP cultivator Green fodder barley was recorded with (Giza127) the value increase from7.67% in seed to 8.44%in sprouting. The DDM and DMI were significantly decrease in all several cultivator Green fodder barleys compared with seed barley. Also, several cultivator Green fodder barley productions observed significantly decreased of TDN in all strains compared with its seeds. The parameters of energy values are predication from chemical composition of Egyptian barley for seed (Giza 128, Giza 127, Giza 130, Giza 129, Giza 126, and Giza 123) and it green fodder production observed significantly decreased of GE, NEL, NEM, NEg, DE and ME in all strains barely green fodder production compared with its seeds. Except the highest result prediction growth energy were recorded with seed Giza (129) compared with other barley strains, the values increase from 1.58 to 1.6 (MJ/Kg DM). Apparent dry matter and true dry matter digestibility by determination In-Vitro DaisyII incubator. The values in all several barleys green fodder was significant increase compared with its seeds. The highest values of seed barley were recorded with strain (Giza129) compared with other seed strains. Also, the best significant (P<0.05) values of data barley for green fodder production recorded with strains (Giza 129) compared with other strains (Giza 128, Giza 127, Giza 130, Giza 126, and Giza 123). Finally, the best significant (P<0.05) values of apparent dry matter and true dry matter digestibility of green fodder production was observed with strains (Giza129). The obtained results indicated that the highest values of economic production and profit were gained by Giza 127 and Giza 129 which gave 39.8 and 38.3LE/m2, 7.1 and 7.0 respectively with constant of other production costs. Conclusion This process takes place in a very versatile and intensive hydroponic growing unit, where only water and nutrients are used to produce a grass and root combination that is very highest values in nutrients, in physical characteristics, in digestibility analysis, high in protein and production costs. The best result recorded with Sprouted barley yield using Egyptian barley Giza 129 barely cultivar could be used animal’s diets as hydroponic green forage in short period (8 days – 3.5 production cycles /month) any time from year. Under the conditions of this experiment, the fodder strains (Giza 129) best results indicated could be used animal’s diets. These feeds are suitable for use at all types and categories of animals. | ||
