INTRODUCTION



A major problem in dairy cattle production in Indonesia is low quantity and quality of feed.



M ostly the feed of dairy cattle is roughage, however due to the lack

f land ownership the production

quality cultivated grass is low.



Green house fodder (GHF) can be used as an alternative to produce high quality fodder.



Benefits of GHF are: CP and digestibility increase, increased of availability some vitamin.

INTRODUCTION

 Green house fodder (GHF) or

hydroponic fodder is a vertical

planting system with hydroponic systems in greenhouses that produce high-quality forage



Used grain, such as: corn, wheat, barley, sorghum, act.



Aspect influence on yield and quality of GHF are:



nutrient solution, seed density, temp, light, watering system, etc.

 Bioslurry is effluent that produced from biogas digester containing rich nutrient for plant.

OBJECTIVES

 T

know the effect of bioslurry from biogas

digester as nutrient solution and seed density on production and quality of corn hydroponic fodder.

CONCLUSIONS

 GHF increased CP content of corn grain from 8% to 14%,

without significant CF change.

 The application of 25% bioslurry as nutrient source and

medium seed density (45 g/ 100 cm2) produced highest corn GHF yield and higher digestibility.
