Probiotic yeast improves animal intestinal digestion

Improving feed efficiency is a powerful tool for improving ruminant sustainability. A good way to achieve this goal is to increase the fiber digestibility of local forages. Yeast probiotic 益生菌 益生菌 supplements have helped farmers achieve this goal. New data on local pastures in Vietnam are explained here.提高饲料效率是提高反刍动物可持续性的有力手段。实现这一目标的一个好方法是提高当地牧草的纤维消化率。酵母益生菌补充剂帮助农民实现了这一目标。这里解释了越南当地牧场的新数据。

Many trials have shown that yeast probiotics 酵母益生菌 酵母益生菌 improve rumen conditions, as measured by redox potential (Eh), which is an indicator of the rumen fermentation process. By enhancing the anaerobic rumen environment, lactic acid utilizing bacteria and fibrinolytic bacteria increase, thereby reducing the risk of rumen acidosis and improving fiber digestibility.许多试验表明，酵母益生菌改善了瘤胃条件，通过氧化还原电位(Eh)来测量，这是瘤胃发酵过程的一个指标。通过改善瘤胃厌氧环境，增加乳酸利用菌和纤溶菌，从而降低瘤胃酸中毒风险，提高纤维消化率。

The increase in fiber digestibility directly affects animal performance and efficiency. They investigated the relationship between neutral detergent fiber digestibility (NDFD) and animal production performance.They estimated that an increase in in vitro or in situ NDFD by 1 unit was associated with an increase in dry matter intake (DMI) by 0.17 kg/d, an increase in milk production by 0.23 kg/d and a 4.0% increase in fat by 0.25 kg/d-corrected milk (FCM) ) .纤维消化率的提高直接影响动物生产性能和生产效率。研究了中性洗涤纤维消化率(NDFD)与动物生产性能的关系。他们估计，体外或原位NDFD每增加1单位，干物质采食量(DMI)增加0.17 kg/d，产奶量增加0.23 kg/d，脂肪增加4.0% (0.25 kg/d校正乳(FCM))。

Various forages with different NDF contents were tested试验了不同NDF含量的饲料

Ruminal fluid was collected from 3 Holstein dry cows fed a standard cow diet consisting of high fiber and low starch, and further used in an in vitro fermenter. Ruminal juice was removed from all 3 cows and mixed to obtain an average sample to minimize variability in individual microbiomes. The researchers aimed to compare the rumen degradability of local Vietnamese forages with that of French/European pastures and secondly to assess the effect of yeast probiotics 酵母益生菌 酵母益生菌 on rumen degradability of Vietnamese forages.选取3头饲喂高纤维低淀粉标准奶牛日粮的荷斯坦干奶牛，收集瘤胃液，并在体外发酵罐中使用。将所有3头奶牛的瘤胃汁液取出并混合以获得平均样品，以尽量减少个体微生物组的差异。本研究旨在比较越南当地牧草与法国/欧洲牧草的瘤胃降解率，并评估酵母益生菌对越南牧草瘤胃降解率的影响。选取3头饲喂高纤维低淀粉标准奶牛日粮的荷斯坦干奶牛，收集瘤胃液，并在体外发酵罐中使用。将所有3头奶牛的瘤胃汁液取出并混合以获得平均样品，以尽量减少个体微生物组的差异。研究人员旨在比较越南当地牧草与法国/欧洲牧草的瘤胃降解率，其次评估酵母益生菌酵母益生菌酵母益生菌对越南牧草瘤胃降解率的影响。

The fermenters were then "fed" a lactation diet consisting of a complete mixed ration (TMR) to simulate rumen fermentation. After 2 weeks of acclimation, the digestibility of the different forages was calculated. Two in vitro techniques were used in this experiment: double flow and daisy incubator.然后给发酵罐“喂食”由完全混合日粮(TMR)组成的哺乳日粮，以模拟瘤胃发酵。驯化2周后，计算不同饲料的消化率。本实验采用双流培养和雏菊培养两种体外培养技术。然后给发酵罐“喂食”由完全混合日粮(TMR)组成的哺乳日粮，以模拟瘤胃发酵。驯化2周后，计算不同饲料的消化率。本实验采用双流培养和雏菊培养两种体外培养技术。

Dual flow 二元流 二元流

The in vitro model was designed to simulate rumen fermentation for at least 3 weeks. pH values were changed similarly, for example, by periodically injecting artificial saliva into the rumen for microbial fermentation. Physicochemical, fermentation and microbiological parameters are monitored in real time and continuously. The dual-flow digestion simulator feeds a complete TMR daily, just like a normal cow's diet.体外模型模拟瘤胃发酵至少3周。pH值也发生了类似的变化，例如，通过定期将人工唾液注射到瘤胃中进行微生物发酵。物理化学，发酵和微生物参数的实时和连续监测。双流消化模拟器每天喂养完整的TMR，就像普通奶牛的饮食一样。体外模型模拟瘤胃发酵至少3周。pH值也发生了类似的变化，例如，通过定期将人工唾液注射到瘤胃中进行微生物发酵。物理化学，发酵和微生物参数的实时和连续监测。双流消化模拟器每天喂养完整的TMR，就像普通奶牛的饮食一样。

Daisy Incubator 黛西孵化器 黛西孵化器

This in vitro model is designed to simulate the degradability of feed components in the rumen. Ruminal inoculum is divided into 4 digestive anaerobic tanks instead of the individual flasks or test tubes seen in traditional methods. The jars were kept at a constant temperature (39.5°C) and stirred well for 48 hours. Samples from the study (#100) were sealed in filter bags and incubated in the fermenters.该体外模型旨在模拟饲料成分在瘤胃内的降解率。瘤胃接种物分为4个消化厌氧罐，而不是传统方法中单个的烧瓶或试管。在恒温(39.5°C)下搅拌48小时。研究样品(#100)密封在过滤袋中，并在发酵罐中孵育。该体外模型旨在模拟饲料成分在瘤胃内的降解率。瘤胃接种物分为4个消化厌氧罐，而不是传统方法中单个的烧瓶或试管。在恒温(39.5°C)下搅拌48小时。研究样品(#100)密封在过滤袋中，并在发酵罐中孵育。

Degradability differences降解性差异

The results of the in vitro experiments showed significant differences in the degradability of the forages with higher fiber content (> 50% NDF) in terms of rumen dry matter (DM) degradability体外试验结果表明，高纤维含量(> 50% NDF)的牧草瘤胃干物质(DM)降解率差异显著体外试验结果表明，高纤维含量(> 50% NDF)的牧草瘤胃干物质(DM)降解率差异显著

Secondary correlations showed a correlation between %NDF of pasture and degradability of additional rumen DM when added to yeast probiotic products. Interestingly, yeast probiotics had a more significant effect on pastures with higher NDF content. The degradability of NDF was significantly increased by the addition of yeast probiotics. Correlation between %NDF of forage and rumen DM degradability. Not surprisingly, forages with higher NDF content exhibited lower rumen degradability. However, when the yeast probiotic product was added, it showed a more significant effect on the degradation of higher NDF percentages of forage.次级相关性表明，添加酵母益生菌产品时，牧草NDF %与瘤胃DM的可降解性相关。有趣的是，酵母益生菌对NDF含量越高的牧场效果越显著。添加酵母益生菌可显著提高NDF的降解率。饲料NDF %与瘤胃DM降解率的相关性。不出意外，NDF含量高的饲料瘤胃降解率较低。然而，当添加酵母益生菌产品时，对较高NDF百分比的饲料的降解效果更为显著。次级相关性表明，添加酵母益生菌产品时，牧草NDF %与瘤胃DM的可降解性相关。有趣的是，酵母益生菌对NDF含量越高的牧场效果越显著。添加酵母益生菌可显著提高NDF的降解率。饲料NDF %与瘤胃DM降解率的相关性。不出意外，NDF含量高的饲料瘤胃降解率较低。然而，当添加酵母益生菌产品时，对较高NDF百分比的饲料的降解效果更为显著。
