Effect of Natures Way, MSE Probiotic on Lactation Performance of Dairy Cows

Study conducted by Dr. William K. Sanchez, University of Idaho

Methods: A two period 21-d period cross over design was conducted to evaluate the effect of Natures Way, MSE Probiotic on lactation performance of Holstein dairy cows at the University of Idaho. A total of twenty cows was assigned either to a control diet or the control diet with MSE. A copy of the control diet is enclosed. The MSE probiotic was fed at 10 g/hd/d in a top dressed supplement of 37 lb with 50% ground corn and 50% dried molasses.

Daily DMI was collected following 14 d of adaptation (wk 3 of each period) and was averaged and analyzed statistically. Daily milk yield were collected during wk 3 of each period averaged and analyzed statistically. Milk components; fat, protein, SNF, SCC were evaluated from six consecutive milkings during wk 3 of each period. Components were weighted on a milk yield basis and analyzed statistically BW and body condition score changes were evaluated by measuring beginning and ending values at each period and averaged and analyzed statistically.

Results Calculated ingredient composition and analysis are presented in Tables 1 and 2. Lactational performance is presented in Table 3. The MSE supplement tended to increase (P < 0.1) Milk, fat, protein, solids not-fat (SNF), 3.5% fat-corrected milk yield, and energy-corrected milk yield. Body weights of cows fed the MSE product also tended to be greater (P < 0.1) than cows not fed the MSE product.

Conclusion Natures Way, MSE Probiotic has potential to enhance Lactational Performance of Dairy Cows. A field study is recommended to validate these results and test the product in a commercial setting.
