Evaluation of Supplementing Brewer's Yeast to Lactating Dairy Cows
… the ration of a lactating dairy cow by assessing milk yield and composition, blood metabolites, rumen fermentation, and feed intake and efficiency. We hypothesized that diets containing a concentrated brewer’s yeast supplement would increase milk and component yields, benefit rumen fermentation, …

Effects of mixer type on utilization of diets with increasing amounts of modified wet distillers grains with solubles for lactating dairy cattle
… unaffected by MWDGS concentration (P = 0.39). Milk production did not differ (P = 0.75) by concentration of MWDGS or by interaction of MWDGS × mixer (P = 0.18). Milk protein content tended (P = 0.09) to decrease linearly with increasing MWDGS. Milk fat percentage declined with increasing MWDGS …

The Feeding Value of Corn Distillers Solubles for Lactating Dairy Cows
… was similar (P > 0.10) for all diets. Milk yield (33.8, 36.2, 35.5, 36.0, and 36.0 kg/d) tended (P < 0.10) to be higher for diets 2 to 5 than for diet 1 while yields of fat (1.03, 1.02, 1.04, 1.06, and 1.04 kg/d) and protein (0.99, 1.03, 1.01, 1.03, and 1.04 kg/d), fat percentage (3.04, …

Soybean Meal Substitution with a Microbial Protein Source in Dairy Cow Diets
… KY) in substitution for soybean meal on milk production, dry matter intake, rumen, and blood parameters of high producing dairy cows. Sixteen Holstein cows (twelve multiparous and four primiparous) with 93 ± 37 DIM were used in a 4 x 4 Latin square design with four 28 d periods. Cows were …

Effects of Maturity at Harvest of Triticale and Dietary Forage Inclusion on Production Performance, Nutrient Utilization, and Milk Fatty Acid Profile of Lactating Dairy Cows
… diets containing BS silage produced more milk per day than cows consuming diets containing SDS silage. This response was observed when feeding both LF and HF diets. The maturity of the forage (BS vs. SDS) did not affect the apparent total tract digestibility of neutral detergent fiber …

Replacing Corn and Soybean Meal in Lactating Dairy Cow Diets with Field Peas (Pisum Sativum)
… sativum L.) in lactating dairy cow diets on milk production, dry matter intake and ruminal characteristics. The experiment used 16 lactating Holstein dairy cows (nine primiparous and seven multiparous) in a 4 x 4 Latin square design with 28 d periods. Cows were blocked into squares by parity, …

Utilizing near-infrared technology to assess changes in corn silage dry matter and the effects of feeding a starling resistant supplement to dairy cattle
… when the factory preset calibrations were corrected for bias. While the food dehydrator over-estimated the DM of the corn silage and the Koster Tester accurately predicted DM. Study 2 was designed to evaluate the lactation performance of post-peak dairy cattle when using a starling …
