The effect of EM-4 dosage in fermentation on the quality of soy milk waste (SMW) as an alternative feed ingredient to increase production cost efficiency in the poultry business

Abstract

The increasing consumption of soy milk, especially in European countries, has an impact on high soy milk production. This causes increasing the waste and it will have an impact on environmental pollution. This research aims to obtain the best dose of EM-4 in fermented soy milk waste (SMW) as an alternative feed to increase production cost efficiency in the poultry business. This research was conducted with laboratory experiments using a completely randomized design (CRD). This research used 5 levels of EM-4 (0; 2.5; 5; 7.5 and 10%) and each treatment was repeated 4 times. Statistical analysis showed that the EM-4 level was very significant (p<0.01) in increasing the quality of texture, moisture content, temperature, sugar and crude protein; reduce crude fiber; and significantly (p<0.05) improved SMW color. The average SMW texture score ranges from 1.00-3.00; moisture content (12.75-15.10%); temperature (27.68-29.33°C); sugar concentration (0.00-5.00%); crude protein (13.66-18.68%), crude fiber (5.07-9.67) and color score (2.50-3.75). It was concluded that fermentation using EM-4 as an inoculum could improve the quality of soy milk waste (SMW) as an alternative feed to increase production cost efficiency in the poultry business. The best quality of SMW was obtained in fermentation with an EM4 level of 7.5%
