摘要
This study was conducted to investigate the effects on fermentation characteristics of rumen microorganism by different types and levels of lignosulfonate treated soybean meal (LSBM) in in vitro test and rumen simulation continuous culture (RSCC) system in dairy cows. The experiment I was control and 12 treatments (each with 3 replications) in vitro test to demonstrate composition of different types of treatments with lignosulfonate (Desulfonate, Na, Ca and solution) and levels (2, 4 and 8%) of soybean meal in the dairy cow diet. LSBM source treatments in the dairy cow diet showed pH value, -N concentration and total VFA concentration lower than control at all levels and incubation times (p<0.05). Dry matter digestibility of LSBM source treatments showed lower than control (p<0.05). Gas production and rumen microbial synthesis was decreased by rumen microbial fermentation for incubation times. Undegradable protein (UDP) concentration of all LSBM treatments was decreased for incubation times, and significantly higher than control (p<0.05). In the experiment II compared diets of the control, LSBM Na 2%, LSBM Sol 2%, which are high performance to undegradable protein (UDP) concentration experiment I in vitro test, and heated treatment lignosulfonate (LSBM Heat) 2% in the dairy cow diet from four station RSCC system ( Latin square). A rumen microbial fermentation characteristic was stability during 12~15 days of experimental period in all treatments. The pH value of LSBM treatments was higher than control treatment (p<0.05). The -N concentration, VFA concentration and rumen microbial synthesis of LSBM treatments were lower than control (p<0.05). The undegradable protein (UDP) showed LSBM Na 2% (45.28%), LSBM Sol 2% (43.52%) and LSBM Heat 2% (43.49%) higher than control (41.55%), respectively (p<0.05). Those experiments were designed to improve by-pass protein of diet and milk protein in the dairy cows. We will conduct those experiments the in vivo test by LSBM treatments in dairy cows diet.

本研究旨在探讨不同类型和水平的木质素磺酸盐处理豆粕（LSBM）在奶牛体外试验和瘤胃模拟连续培养（RSCC）系统中对瘤胃微生物发酵特性的影响。实验我是对照和12个处理（每个重复3次）体外测试，以证明木质素磺酸盐（脱磺酸盐，钠，钙和溶液）和豆粕水平（2,4和8％）的不同类型处理的组成奶牛的饮食。奶牛日粮中的LSBM源处理显示在所有水平和孵育时间的pH值，-N浓度和总VFA浓度低于对照（p <0.05）。 LSBM源处理的干物质消化率显示低于对照（p <0.05）。瘤胃微生物发酵培养时间减少了气体产生和瘤胃微生物合成。所有LSBM处理的不可降解蛋白（UDP）浓度在孵育时间下降，并且显着高于对照（p <0.05）。在实验II中比较对照饮食，LSBM Na 2％，LSBM Sol 2％，这是高性能至不可降解蛋白（UDP）浓度实验I体外试验，并在乳品中加热处理木质素磺酸盐（LSBM Heat）2％来自四站RSCC系统（拉丁方）的牛饮食。瘤胃微生物发酵特性在实验期间的12~15天内均为稳定性。 LSBM处理的pH值高于对照处理（p <0.05）。 LSBM处理的-N浓度，VFA浓度和瘤胃微生物合成均低于对照（p <0.05）。不可降解蛋白（UDP）分别显示LSBM Na 2％（45.28％），LSBM Sol 2％（43.52％）和LSBM Heat 2％（43.49％）高于对照（41.55％）（p <0.05）。这些实验旨在改善奶牛的饮食和乳蛋白的旁路蛋白质。我们将通过LSBM治疗奶牛饮食进行体内试验。
