Response of Lactating Dairy Cows to Small and Large Amounts of Dried Whey in the Concentrate Mixture
… mix fed to lactating dairy cows increase d milk fat percentage, but decreased milk production. In order to determine if the increased fat percentage was a positive response to dried whey in the ration, or an artifact of drying off the cows early, 5% dried whey product (DWP) was included in …

Interactions of Bovine Somatotropin and Nutrition on Milk Production and Composition of Dairy Cows
… 1.74 Meal NEL/kg DM, with additional energy as fat from extruded soybeans and calcium salts of fatty acids. Diets were 50:25:25 concentrate: alfalfa hay: corn silage (DM basis). Bovine somatotropin increased yields of milk (37.9 versus 40.9 kg/day) and of 4% fat-corrected milk (32.3 versus 35.7 …

Risk of Milk Fat Depression for Dairy Cows Fed High Moisture Corn and Distillers Grains in Diets Containing Monensin
… exist that when distillers grains are fed milk fat may be depressed. Likewise feeding an ionophore, monensin, will increase efficiency of milk production. Feeding monensin has also been associated with decreased milk fat production. Lastly, feeding large quantities of highly fermentable …

Production changes related to labor management in Virginia dairy herds
… before hiring were associated with 955 kg more fat corrected milk per year. Herds where herds persons worked many hours for low pay had the largest increase in days open from 1978 to 1986. Milkers with more education were associated with a larger increase in fat corrected milk, but employment …

Protein Nutrition of Dairy Cows During the Transition Period
… postpartum tended (P = 0.10) to produce more 4% fat-corrected milk (FCM) than SB-fed cows (33.8 vs 31.8 kg/d). Gross efficiency (FCM/DMI) was greater (P < 0.05) for the cows fed AMP postpartum than for cows fed SB (1.88 vs 1.70). An interaction of postpartum diet by week (P < 0.05) indicated that …

Effect of dietary protein degradability and fat on rumen, blood and milk components of Jersey and Holstein cows
… dietary protein degradability and supplemental fat on rumen, blood, and milk components. Diet dry matter contained 16% CP with two levels of rumen undegradable protein (RUP) obtained by substituting blood meal for soybean meal. Treatments were 29% RUP, 0% added fat; 29% RUP, 2.7% added fat …

Effect of protein source on milk composition of cows fed low fiber, high grain diets
… were > 75% TDN and ~ 16% acid detergent fiber. Milk yield was not different between treatments. Milk fat percent, milk lactose percent, and fat corrected milk yield were higher in cows on CG (3.13%, 5.30%, 23 kg) in contrast to cows receiving FM (2.11%, 5.00%, 20.5 kg). Milk protein percent was …

A comparison of the influence of barn-cured and field-cured alfalfa hay on milk production
… alfalfa hay out from the same field on milk production and liveweight of dairy cows. Twelve Holstein cows were used in this trial. The double-reversal feeding method was followed. Grain was fed at the same rate to each group of cows. Hay was fed as the only source of roughage, and equal …

Lactational Evaluation of Ruminally Protected Methionine in Diets Containing Extruded Soybeans and Urea
… wk 4 postpartum and continued through wk 16 with milk production and composition during wk 3 postpartum used as covariates. Cows were fed a 16.0% crude protein total mixed diet of (dry matter basis) 40% corn silage, 10% alfalfa hay, and 50% concentrate mix. Yields of milk (33.8 and 35.0 kg/d) and …

Day-to-Day Variation in the Feed Consumption of Dairy Cows in Early Lactation
… complete-block design. Weekly means of DMI, milk production, and body weight were analyzed. Individual cow daily DMI data were fitted to the exponential model. There was no effect of treatment on these variables or the fractional rates of increase in DMI. Multiple regression analysis …

Offering sodium bentonite and sodium bicarbonate free-choice to lactating dairy cattle
… among diets for blood and fecal observations or milk protein. Urine specific gravity was lower in both breeds when sodium bicarbonate was force-fed. Holsteins force-fed sodium bicarbonate had greater intake and milk production than Holsteins not force-fed. In Jerseys, milk urea nitrogen (MUN) …

The Use of Whole-Rolled Sunflower Seeds with or without Additional Limestone in Lactating Dairy Cattle Rations
… to treatments, grouped according to previous milk production and lactation number. The cows were fed one of three diets: 1) the control was a com-soybean meal mix (CSM), 2) com-soybean meal mix plus 22% whole-rolled sunflower seeds, and 3) a corn-soybean meal mix with 22% whole-rolled …

Extruded Blend of Soybean Meal and Sunflower Seeds for Dairy Cattle in Early Lactation
… alfalfa haylage, and 43% concentrate. Yields of milk (33.6 and 33.8 kg/day) and 4% fat-corrected milk (30.9 and 30.5 kg/day) were similar for cows fed SBM or SSF, while percentages of total solids (11.92 and 11.38), fat (3.55 and 3.30), protein (2.91 and 2.74), and solids-not-fat (8.38 and 8.09) …

Determination of the Optimal Time in the Lactation Cycle to Start Feeding a Direct-Fed Cellulase/Xylanase Enzyme Mixture to Dairy Cows
… theclose-up dry period, at calving, or at peak milk production. Cows were blocked by calving date and, within blocks, randomly assigned to one of four treatment diets. Treatments were: 1) an untreated control diet, 2) enzyme addition to the forage from wk 6 to 18 postpartum, 3) enzyme addition …

Effects of Replacing Forage Fiber with non-Forage Fiber in Lactating Dairy Cow Diets
… as DDG replaced corn silage in the diet. Milk protein percentage, protein yield, milk lactose percentage and lactose yields were increased. Milk fat percentage, fat yield and feed efficiency were decreased as the percentage of DDG increased in the diets. Milk yield, energy-corrected milk …

Feeding Value of Brown-Midrib Corn Silage for Lactating Dairy Cows

Replacement of Starch from Corn with Non-Forage Fiber from Distillers Grains in Diets of Lactating Dairy Cows
<p>Forty Holstein cows averaging 78 din milk were used in completely randomized design with a 2-wk covariate period followed by a 6-wk experimental period to evaluate incremental substitution of non-forage fiber provided by dried distillers grains with solubles (DDGS) and soyhulls (SH) for starch …

Relation of cow families to milk production, reproductive efficiency, and longevity

Heat-Treated Soybean Proteins for Lactating Dairy Cattle
… concentrate mix lower in protein and higher in fat than intended. Milk production was higher for the cows fed HSBM due to either the higher amount of protein that they received and/or the lower protein solubility of that diet. No change was seen in milk fat percent, protein, protein components …
