Alternative Analytical and Experimental Procedures to Explore Rumen Fermentation as Driven by Nutrient Supplies
… while minimizing the environmental impact. Rumen fermentation is the focal point of the productivity and efficiency of the animal and numerous chemical, physical and biochemical interactions make the rumen a complex ecosystem. Therefore, improving the understanding of fermentation dynamics …

Effects of iso-alpha-acids on rumen fermentation and comparison of microbial populations between rumens and continuous culture fermenters
… dual-flow continuous culture fermenters to study rumen fermentation in vitro. The first experiment examined the effects of iso-alpha-acids from Humulus lupulus (Hops) extract on rumen fermentation. Iso-alpha-acid extract (IE) was provided to continuous culture fermenters to supply 0 (CON), 600 …

Effects of Peripartal Supplementation of Yeast-Based Products on Performance, Rumen Fermentation Profile, and Circadian Rhythms in Dairy Cows
… have shown beneficial results on performance and rumen fermentation profile in dairy cows. This study aimed to evaluate the effects of a yeast-derived postbiotic prototype (PB) on lactation performance in dairy cows supplemented during the transition period until 60 DIM. Sixty-one Holstein dairy …

Effect of nitrogen and energy supplementation on intake, digestibility and rumen fermentation efficiency in sheep fed poor quality Eragrostis curvula hay
… In Trial 1, urea partially substituted the rumen degradable nitrogen (RDN) fraction of sunflower meal (SFM). Neutral detergent fibre (NDF) digestibility was higher in the treatments where urea substituted 45% and 60% of the RDN fraction of SFM. Treatment did not affect roughage intake, rumen …

Effects of Sodium Bicarbonate, Sodium Chloride, Limestone, and Monensin on Rumen Fermentation, Rumen Fluid Dilution Rate, and Nutrient Utilization in Ruminants
… of mineral salts and monesin to alter the rumen environment and the efficiency of nutrient utilization in ruminants.

The effect of trace mineral source on solubility, rumen fermentation characteristics, and trace mineral concentration in protozoa and bacteria of steers consuming a lactation dairy type diet
… of trace mineral (TM) source on TM solubility, rumen fermentation characteristics, and trace mineral concentration in protozoa and bacteria of steer consuming a lactation dairy-type diet. Experiments 3 and 4 were classified as experiments 1 and 2 in chapter 3 for publication purposes in academic …

Growth Performance, Nutrient Utilization, and Metabolic Profile of Dairy Heifers Fed Diets High in Distillers Grains with Different Forage to Concentrate Ratios
… ratios. The effects on growth, feed efficiency, rumen fermentation, nutrient digestibility, metabolic profile and onset of puberty, as well as post trial performance were investigated. First, a 16-wk feeding trial was conducted using 48 Holstein heifers to evaluate effects of dietary treatment on …

EVALUATION OF A METHOD TO MEASURE VOLATILE FATTY ACIDS AND GASES IN VITRO WITH MATHEMATICAL MODELING
… estimate gas production and VFA profile in rumen fermentation would enable isolation of fermentation effects from various animal interactions. Therefore, the focus of this dissertation was to develop an in vitro method that will have the same VFA and gas profiles as in the rumen. The …

Characterizing Thiamine Status and Mechanisms of Thiamine Supplementation on Subacute Ruminal Acidosis Attenuation in Dairy Cows
… which is characterized by prolonged decrease in rumen pH and high levels of lipopolysaccharide (LPS). SARA challenge has been confirmed to severely impair animal health, production performance and farm profitability, and more and more attentions have been paid to prevent the occurrence of SARA in …

Strategies to Decrease Incidence of Fatty Liver in Dairy Cows
… without monensin. Monensin tended to modulate rumen fermentation, particularly in cows fed the 2-stage diet strategy. Supplemental monensin increased milk production and had neutral or positive effects on rumen fermentation and rumen dynamics. Neither the higher energy closeup diet in the …

Assessing Availability and Utilization of Essential Amino Acids in Dairy Cattle Using Stable Isotope Based Approach
… in ruminant is a big challenge due to the rumen fermentation and complicated post absorption utilization. Current techniques used for direct determination of AA absorption and metabolism are laborious and expensive with large variation. The objectives of this project were to investigate AA …

Evaluation of Supplementing Brewer's Yeast to Lactating Dairy Cows
… 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, and improve feed efficiency and nutrient …

IN VITRO AND OMICS METHODOLOGIES APPLIED TO ANIMAL NUTRITION TO ADDRESS FEED-FOOD COMPETITION AND GREENHOUSE GAS EMISSIONS
… to reduce methane production from enteric fermentation and ammonia in ruminants. The first research project involved the study of the metabolic impact of the dietary inclusion of salty and sugary former food products (FFPs) in pigs from the weaning phase to the finishing phase. To do this, …

Effect of roughage to concentrate ratio on ruminal fermentation and protein degradability in dairy cows
… it might be beneficial to increase the amount of rumen undegradable protein (RUP) that passes out of the rumen, through manipulation of rumen fermentation to establish a lower rumen pH. To test this hypothesis, a study was conducted in which three ruminally cannulated Holstein cows, 722 kg ±25.6 …

Evaluation of chitinous materials as a feed for ruminants
Chitinous products were investigated by in vivo rumen fermentation. Samples of cockroaches, grasshoppers, shrimp shells, crabmeal, and purified chitin were placed in the rumen of fistulated steers. Average rumen solubility (weight loss from a nylon bag) of 66.5. 32.0, 17.4, 35.7, and 21.5%, …
