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 …

The effect of supplementary maize silage on rumen function in dairy cows grazing high quality pasture : A thesis submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science with Honours at Lincoln University
… is in contrast to previous literature involving total mixed ration systems. However, while animals supplemented with the maize silage had an increased mean rumen pH, there was also an increase in the mean number of daily bouts below pH 5.5 (2.4 v. 1.5), though the mean duration of each bout did …

Sensorial, cultural and volatile properties of dairy powders, yoghurt and butter from pasture and non-pasture cow diets
… and white clover) and cows indoors on trial mixed rations. Cross cultural sensory analysis was also undertaken on skim milk powder from these diets in order to determine if consumers and trained panellists perceived skim milk powder differently based on diet but also on product familiarity …

Milk fat response to chopped and ground hay when added to or ensiled with corn silage and fed in complete rations to dairy cows
… hay was added to corn green chop at 12.5% of the total forage dry matter before ensiling (CE and GE). Chopped or ground hay was also added to the control silage at the same rate prior to feeding (CA and GA). Silages were supplemented to contain 14% crude protein and 1.67 Mcal/kg on a dry matter …

Intake capacity of the Icelandic dairy cow. Effect of animal factors, concentrate ratio and feeding method
… intake (DMI) is crucial to formulate a feed ration that maximizes feed efficiency. The model predicting the DMI of the Icelandic dairy cow in the co-Nordic feed evaluation system NorFor needed an update to be able to predict the DMI more accurately. The aims of this study were to collect new …

Lactase Activity in Steers Fed Large Amounts of Dried Whey
… dried whole whey (86% of concentrate mix, 60% of total dry matter intake) were fed to four Holstein steers in place of corn and soybean meal in the control diet to evaluate the extent and site of lactose digestion in the ruminant's digestive tract. Diets consisted of 70% of the dry matter as …

Growth, body composition and costs of feeding Holstein heifers
… area. When moving grazing heifers to drylot a total mixed ration with fishmeal or soybean meal as protein sources gave similar responses. DM intake of grazing heifers ranged from 8.1 to 10.1 kg/d, vs 7.5 kg/d for arylot. Supplementing grazing heifers with degradable or undegradable protein gave …

Impact of Precision Feeding Strategies on Whole Farm Nutrient Balance and Feeding Management
… monthly from individual feedstuffs and each total mixed ration (TMR) fed to lactating cows. Control farms submitted TMR samples every 2 mo. Standard wet chemistry analysis of samples was performed. Data stored in the software were collected monthly from each treatment farm concurrent with …

Financial Performance of Pasture-Based Dairies: A Virginia Case Study
… based on the intensity of pasture use, from total confinement to seasonal farms using intensive grazing (in which pasture, hay, and energy supplements are the only sources of nutrients for all dairy animals on the farm). Results of the analysis demonstrate that pasture-based seasonal …

The Feeding Value of Corn Distillers Solubles for Lactating Dairy Cows
… distillers grains with solubles (DOGS) in the total mixed ration. The forage portion of the diets was kept constant at 27 .5% corn silage and 27.5% alfalfa hay (DM basis). Diets were: 1) 0% distillers grains products (control), 2) 18.5% DOGS, 3) 10% CCDS, and 4) 20% CCDS, and 5) a combination …

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 …

Investigating the effect of yeast and mineral dietary supplements during the periparturient period on the production, physical health, and innate immune system of dairy cows
… Different dietary strategies through ration formulation or supplementing feed additives have been employed to mitigate these negative effects. The objectives of this dissertation were to: 1) investigate the effects of supplementing products derived from Saccharomyces cerevisiae culture …

Metabolic effects of incremental exercise on Arabian horses fed diets containing corn oil and soy lecithin
… exercise. When it is combined with corn oil in a total mixed ration, soy lecithin is both highly digestible and palatable to horses. Our objectives in this study were to compare the effects of incremental exercise and isocaloric control (CON), corn oil (CO), and a soy lecithin/corn oil (LE) diets …

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 …

Effects of mixer type on utilization of diets with increasing amounts of modified wet distillers grains with solubles for lactating dairy cattle
… mixer type as the whole plot and MWDGS concentrations as subplots in a 3 x 3 Latin square arrangement with 35-d periods. Inclusion rates of MWDGS were 10, 20, and 30% of dietary DM, primarily replacing corn, SBM, and whole cottonseed. Feed DMI was less for KMF (P = 0.05), but was unaffected by …

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 …
