Table 5 Summary of studies in periparturient dairy cows investigating the effects of supplemental live yeast or yeast-based products on performances in the prepartum and Early lactation

From: Role of nutraceuticals during the transition period of dairy cows: a review

Nutraceutical Treatment Period Main outcome Reference
Live yeast 5 g/d/head Early lactation (40 d in milking) Greater VFA and rumen pH
Greater fibrolytic and lactate-using bacteria
[108]
2.5 g/d/head precalving and 10 g/d/head postcalving From − 14 to 70 d relative to parturition Higher rumen acetate proportion and lower ammonia nitrogen in early lactation
Greater % of milk fat
[109]
Yeast culture 56 g/d/head From calving to 14 weeks postpartum Greater milk yield, + 1.4 kg/d
+ 1.6 kg/d of 3.5% FCM
+ 1.7 kg/d of ECM
+ 0.07 kg/d of milk fat
[110]
60 g/d/head From − 21 to 140 d relative to parturition Higher DMI in the prepartum, + 2.10 kg/d
Higher DMI in the postpartum, + 1.80 kg/d
[111]
20 g/d/head From − 21/− 28 to 41 d relative to parturition Higher DMI in the first 2 d of lactation, + 5.94 kg/d
+  0.14% of milk fat
[112]
Yeast culture + Enzymatically hydrolized yeast 28 g/d/head From calving to 14 weeks postpartum + 1.6 milk yield, kg/d
+ 1.8 kg/d of 3.5% FCM
+ 1.9 kg/d of ECM
+ 0.08 kg/d of milk fat
+ 0.07 kg/d of milk protein
[113]
Saccharomices cereviseae fermentation product 16.0 ± 0.7 g/d prepartum and 18.9 ± 0.5 g/d postpartum From 29 to 42 d relative to calving + 0.36% of milk fat
+ 0.91 of milk urea nitrogen
Multiparous, higher BHB
[114]
  19 g/d/head From 28 to 42 d relative to calving Supplementing SCFP and reducing dietary starch content after calving may reduce inflammation and improve health status of the animal after calving [115]
  56 or 112 g/d/head From −4 weeks to 4 weeks relative to calving + 5.15 milk yeald, kg/d
+ 0.14 protein, kg/d
+ 0.26 lactose, kg/d
lower SCC (− 80.5 cells/μL)
