Optimization of Technological Parameters and Quality Evaluation of Compound Feed for Weaned Piglets by Solid-state Fermentation with Probiotics
Solid anaerobic fermentation of compound feed for weaned piglets was carried out by compound probiotic combined fermentation technology,and the effects on the quality of fermented feed were explored through different process parameters:inoculation amount,fermentation temperature,fermentation moisture and fermentation time.The results showed that different parameters had a significant impact on the quality of compound feed.The use of 5.0%inoculation amount,35%fermentation moisture,37℃fermentation temperature and 72 h fermentation time could effectively increase the content of crude protein,lactic acid,free amino acids and the number of probiotics in compound feed,reduce the number of molds in fermented feed,improve the flavor and quality of fermented feed,and prevent feed mildew and insect moth.After fermentation,the compound feed was golden in color,aromatic in smell,loose in texture and not sticky.
