Abstract

The objective of this meta-analysis was to analyze the effect of feeding live yeast (Saccharomyces cerevisiae) on feed intake (FI), lactation performance (LP), rumen fermentation (RF), and rumen microbiota (RM) in dairy cattle. We performed a literature search using the Boolean search approach with MeSH keywords, including live yeast, Saccharomyces cerevisiae, S. cerevisiae, feed intake, lactation, performance traits, rumen, fermentation, microbiota, and cattle. Twenty-five (25) articles published contained at least data on feed intake, lactation performance or milk production parameters, rumen fermentation or digestibility, and rumen microbiota measured for experiments involving dairy animals have been selected. Microsoft Excel performed data extraction and organization, and statistical analysis was performed using SPSS. Few studies have observed a negative impact of the LY on the FI (8%), LP (12%), RF (4%), and RM (8%), but the majority of the selected studies reported a positive impact of adding LY (FI: 36%, LP: 52%, RF: 52% and RM: 40%). Cows supplemented with LY showed a marginal decrease in feeding rate; min/d (0.13 vs. 0.14; p=0.65), interval between meals; min (142.1 vs. 1603, p=0.09), meal size; kg of DM/meal (3.4 vs. 3.8, p=0.09), meal duration; min/meal (32.5 vs.35.3, p=0.39), lying boots; no/d (9.5 vs. 9.6, p=0.83), eating boot; bout/day (80.7 vs.8.26, p=0.24), and lying time; min/d (671.1 vs. 697.5, p=0.51). However, LY increases feeding duration; min/d (232.0 vs.226.6, p=0.65), meal frequency; meal/d (9.0 vs.7.8, p=0.07), rumination; min/d (570.3 vs. 344.9, 344.9, p=0.08), and meal criterion with significance; min (20.0 vs. 25.8, p=0.04). Meta-regression of the covariate effect shows that using live yeast products in the cattle diet significantly increased the Lactation Performance (p=.001) and Feed Intake (p=.001). However, it enabled a higher average ruminal Fermentation (p=.005) and microbiota (p=.003). Furthermore, the timing of live yeast culture before calving could influence the performance and ruminal parameters, especially the microbiomes (p=0.006). A little increase in milk yield (1.4kg/day) and lower SCS（somatic cells score (2.76) were observed in LY. This meta-analysis indicated feeding live yeast (Saccharomyces cerevisiae) could improve feeding behaviour, animal performance, and herd productivity (milk and rumen health). However, further research is required to study its effect on feed intake and rumen microbiota in dairy cattle.

饲养活酵母（酿酒酵母）对奶牛饲养行为和泌乳性能、瘤胃发酵和瘤胃微生物群影响的Meta分析

本荟萃分析的目的是分析饲喂活酵母（酿酒酵母）对奶牛采食量（FI）、泌乳性能（LP）、瘤胃发酵（RF）和瘤胃微生物群（RM）的影响。我们使用布尔搜索方法对MeSH关键词进行了文献搜索，包括活酵母、酿酒酵母、酿酒酵母菌、采食量、泌乳、性能性状、瘤胃、发酵、微生物群和牛。已经选择了二十五（25）篇发表的文章，其中至少包含关于饲料摄入量、泌乳性能或牛奶生产参数、瘤胃发酵或消化率以及为涉及乳制品动物的实验测量的瘤胃微生物群的数据。Microsoft Excel进行数据提取和组织，并使用SPSS进行统计分析。很少有研究观察到LY对FI（8%）、LP（12%）、RF（4%）和RM（8%）的负面影响，但大多数选定的研究报告了添加LY的正面影响（FI:36%、LP:52%、RF:52%和RM:40%）。添加LY的奶牛的喂养率略有下降；min/d（0.13vs.0.14；p=0.65），两餐间隔；最小值（142.1对1603，p=0.09），膳食大小；每餐DM kg（3.4 vs.3.8，p=0.09），用餐时间；分钟/餐（32.5 vs.35.3，p=0.39），平躺靴；无/d（9.5 vs.9.6，p=0.83），吃靴子；约/天（80.7 vs.8.26，p=0.24），以及卧位时间；min/d（671.1对697.5，p=0.51）。然而，LY增加了喂养持续时间；min/d（232.0 vs.226.6，p=0.65），进餐频率；膳食/d（9.0 vs.7.8，p=0.07），反刍；min/d（570.3vs.344.9344.9，p=0.08），膳食标准具有显著性；min（20.0 vs.25.8，p=0.04）。协变量效应的元回归显示，在牛日粮中使用活酵母产品显著提高了泌乳性能（p=0.001）和采食量（p=0.000）。然而，它能够实现更高的平均瘤胃发酵（p=0.005）和微生物群（p=0.003）。此外，产仔前活酵母培养的时间可能会影响性能和瘤胃参数，尤其是微生物组（p=0.006）。在LY中观察到产奶量（1.4kg/d）略有增加，SCS（体细胞评分（2.76）较低。该荟萃分析表明，饲养活酵母（酿酒酵母）可以改善饲养行为、动物性能，以及牛群生产力（牛奶和瘤胃健康）。然而，还需要进一步研究其对奶牛采食量和瘤胃微生物群的影响。

Our journal is published quarterly, where the published articles are inserted into areas of animal behaviour, animal biometeorology, animal welfare, and ambience: farm animals (mammals, birds, fish, and bees), wildlife (mammals, birds, fish, reptiles, and amphibians), pets, animals in zoos and invertebrate animals. The publication is exclusively digital and articles are freely available to the international community. Manuscript submission implies that the data are unpublished and have not been submitted for publication in other journals. JABB publishes original articles in the form of Original Articles, Short Communications, and Reviews. Original Articles arising from research work should be well grounded in theory and execution should follow the scientific methodology and justification for its objectives; Short Communications should provide sufficient results for a publication in accordance with the Research Article; Reviews should involve the relevant scientific literature on the subject. JABB publishes articles in English only. All articles should be written strictly adopting all the rules of spelling and grammar.
