The effect of sodium bicarbonate or live yeast culture (Saccharomyces cerevisiae) on the metabolism and production of Lactating dairy cows
… on metabolic indices, digestibility of the total mixed ration (TMR) and milk production and composition in lactating dairy cows. Twenty-eight lactating Holstein cows (77 ± 31 days in milk, 39.4 ± 7.2 kg milk/d) were assigned to blocks by milk production, lactation number, and days in milk …

Impact of Precision Feeding Strategies on Whole Farm Nutrient Balance and Feeding Management
… and installed feed management software (TMR Tracker, Digi-Star LLC, Fort Atkinson WI) between May and October 2006 and received more frequent feed analysis and feedback. Data were collected for calendar year 2005 and 2006 to compute WFNB using software from the University of Nebraska. On …

Flavor effects on feed consumption and performance of dairy cattle in early lactation
… Starting eight days postpartum cows were fed a total mixed ration (TMR) twice daily. Four additives and a control (no additive) were examined in each trial with the most preferred, highest total dry matter (DM) intake, being dropped after 5, 4, 3 and 2 d feeding segments. Sweet (sucrose, 1.5% of …

White clover inclusion in intensive dairy production systems
… the dairy cows with increased rumen ammonia and total VFA concentrations in the rumen of the grass-clover fed cows over those of the grass only and total mixed ration (TMR) fed cows. The farm gate N balance outlined the environmental benefits of white clover inclusion in grazed swards resulting …

Effect of Dairy Cow Diets on the Composition and Processing Characteristics of Milk
… DHA led to reductions in milk yield and concentrations of protein during EL; otherwise, it had little effect on milk composition or on the selected processing characteristics in mid- or late lactation. The comparative effects of three different dairy cow diets or feeding systems on the milk …

Effects of mixer type on utilization of diets with increasing amounts of modified wet distillers grains with solubles for lactating dairy cattle
… was to determine if methods for preparing TMR [Keenan MechFiber (KMF) technology vs. vertical auger (VA) mixer] would alter physical form of the TMR and affect utilization of modified wet distillers grains with solubles (MWDGS). Holstein cows (n = 24 with 12 ruminally cannulated; 144 DIM ± …

Whole-plant corn silage and foliar fungicide: Strategies to improve dairy feed quality and profitability
… ingredients in a properly-formulated total mixed ration (TMR). In the Midwest, a popular ingredient to include in TMR is whole-plant corn silage (WPCS), which is often sprayed with foliar fungicide during growth to decrease disease incidence. Therefore, the objective of this research …

An Evaluation of Feeding a Blend of Essential Oils and Cobalt Lactate to Lactating Dairy Cows
… by 9 wk for data collection. Cows were fed a total mixed ration (TMR) with no treatment (Control) or 0.23 kg/hd/d of a soy hull carrier containing a proprietary blend of EOC to be fed at a rate of 28 g/hd/d. Daily milk production, management level milk (MLM), 3.5% fat corrected milk (FCM), and …

An investigation into novel bacteriocin producers isolated for shelf life extension of dairy products
… different diets, perennial ryegrass (GRS) and total mixed ration (TMR). Using compositional, textural, microbial, and volatile analyses GRS yoghurts were found to contain significantly more protein, less lactose, altered colour and improved late shelf life texture characteristics. TMR yoghurts …

Effects of essential amino acids supply and body condition prepartum on antioxidant, inflammation and mechanistic target of rapamycin pathways in adipose tissue during the periparturient period
… were fed a corn silage- and wheat straw-based total mixed ration (TMR) during late-prepartum and a corn silage- and alfalfa hay-based TMR postpartum. Cows in HBCS had greater overall plasma non-esterified fatty acid concentrations due to marked increases at 7 and 15 d postpartum. Plasma …

Influence of dietary component manipulation and feed management strategies on growth and rumen development of weaned dairy heifers
… in performance when switched to a high forage total mixed ration (TMR; 60% hay) compared to heifers previously fed 60% or 40% concentrate. Additionally, molar proportions of propionate and butyrate were greater when heifers were fed 80% or 60% concentrate, potentially influencing rumen …

Influence of dietary factors on the macro and micro-composition of bovine milk for use in protein ingredient powder manufacture
… ryegrass/white clover pasture (CLV) and indoor total mixed ration (TMR) feeding systems on the composition and functional properties of bovine milk-based protein ingredients. There was a significant effect of feeding system on the concentration of metabolite compounds and B vitamins in skim milk …

Nutritional and environmental stressors and their effects on performance, metabolism, and the immune system of dairy cattle
… MUN and BUN than cows in MM. Liver concentrations of Se and Fe were greater for cows in MM compared to cows in POS. An upregulation of liver GPX1 was observed for cows in POS compared to cows in MM. In the second experiment, 16 multiparous, lactating, Holstein cows were assigned to 1 of 4 …

Effect of exogenous enzymes on ruminal fermentation, pelletability and palatability of blueberry products in equine feed, and the effects of quantity of protein and starch on equine cecal environment
… fermentation of feed is an important consideration for producers of beef and dairy cattle. One method for enhancing fermentation of fiber is application of exogenous fibrolytic enzymes (EFE) to feed. To determine whether method used to apply EFE impacts fermentation parameters by bovine …
