【摘要】:試驗旨在研究不同發(fā)酵時間對乳酸菌發(fā)酵飼料中主要營養(yǎng)物質(zhì)、乳酸菌和乳酸含量的影響。利用植物乳桿菌和嗜酸乳桿菌發(fā)酵由玉米、菜籽粕、棉籽粕組成的混合飼料,發(fā)酵30 d,每隔5 d取樣檢測發(fā)酵飼料中的主要營養(yǎng)物質(zhì)、乳酸菌和乳酸含量。結(jié)果:乳酸菌發(fā)酵飼料粗蛋白、氨基酸、賴氨酸、蛋氨酸、鈣、非植酸磷、氯和鈉等營養(yǎng)物質(zhì)含量顯著高于未發(fā)酵飼料(P0.05);發(fā)酵飼料總能和表觀代謝能顯著低于未發(fā)酵飼料(P0.05);發(fā)酵飼料乳酸菌數(shù)量和乳酸含量顯著高于未發(fā)酵飼料(P0.05),隨著發(fā)酵時間延長,乳酸菌數(shù)量呈明顯下降趨勢。發(fā)酵至第5天,發(fā)酵飼料粗蛋白、代謝能、乳酸菌數(shù)和乳酸含量分別為20.42%、6.19 MJ/kg、19.0×10~7g和137.15 mmol/kg,第10天分別為19.57%、6.13 MJ/kg、12.67×10~7g和147.29 mmol/kg。而且隨著發(fā)酵時間的增加,飼料中粗蛋白、氨基酸、蛋氨酸、總能、代謝能、乳酸菌活菌數(shù)及乳酸均呈二次曲線關(guān)系。提示乳酸菌發(fā)酵飼料在發(fā)酵后5~10 d內(nèi)使用比較適宜。
[Abstract]:The purpose of this study was to study the effects of different fermentation time on the main nutrients, lactic acid bacteria and lactic acid content in the fermented feed of lactic acid bacteria. A mixture of corn, rapeseed meal and cottonseed meal was fermented by Lactobacillus plantarum and Lactobacillus acidophilus. After 30 days of fermentation, the main nutrients, lactic acid bacteria and lactic acid in fermented feed were detected every 5 days. Results: raw protein, amino acid, lysine, methionine, calcium, non-phytate phosphorus were fermented by lactic acid bacteria. The contents of nutrients such as chlorine and sodium were significantly higher than that of unfermented feed P0.05N, the total energy and apparent metabolic energy of fermented feed were significantly lower than that of unfermented feed P0.05N, the amount of lactic acid bacteria and the content of lactic acid in fermented feed were significantly higher than that of unfermented feed P0.05N, and with the increase of fermenting time, The number of lactic acid bacteria decreased obviously. On the 5th day, the crude protein, metabolizable energy, lactic acid bacteria number and lactate content of fermented feed were 20.42MJ / kg 19.0 脳 10 ~ (7) g and 137.15 mmol / kg respectively, and 19.57 ~ 6.13 mg / kg ~ 12.67 脳 10 ~ (7) g and 147.29 mmol / kg 路kg ~ (-1) on the 10th day, respectively. With the increase of fermentation time, the relationship between crude protein, amino acid, methionine, total energy, metabolic energy, number of live lactic acid bacteria and lactic acid was conic. It was suggested that lactic acid bacteria fermentation feed was more suitable to be used within 10 days after fermentation.
