Methane From Lactating Dairy Cattle: Studies For Mitigation, Diurnal Variation, And Role In Energy Metabolism, Jared Vern Judy Dec 2017

Methane From Lactating Dairy Cattle: Studies For Mitigation, Diurnal Variation, And Role In Energy Metabolism, Jared Vern Judy

Theses and Dissertations in Animal Science

Reducing methane production in dairy cattle has received an increased interest due to environmental concerns associated with its potency as a greenhouse gas. Methane represents lost energy in cattle and reduction may increase animal efficiency and productivity. Experiment 1 evaluated strategies of mitigating methane production in lactating dairy cattle with inclusion of dried distillers grains and solubles (DDGS), DDGS with added corn oil, and DDGS with added calcium sulfate and effects on energy and nitrogen balance. Inclusion of DDGS, corn oil, and calcium sulfate, increased DMI and milk yield. Methane production was reduced with addition of corn oil and calcium ...

Aims: The effect of feeding dried distillers grains with solubles (DDGS) or reduced-fat DDGS (RFDG) on ruminal methanogenesis and the rumen bacterial community of dairy cattle was evaluated. Methods and Results: Treatments were CONT, a diet with no distillers grains; DG, inclusion of 20% DDGS; rfDG, inclusion of 20% RFDG; and MIX, inclusion of 10% DDGS and 10% RFDG. Methane emission was measured; rumen bacterial community was evaluated by sequencing the V4 region of the 16S rRNA gene. Total methane production remained unaffected. However, feeding distillers grains tended to reduce methanogenesis per unit of feed intake, decreased the abundance of ...

Kansas Agricultural Experiment Station Research Reports

Kansas State University is pleased to present the 2017 Dairy Research Report of Progress. We continue to watch the Kansas dairy industry grow, and in 2016 our state ranked 10th for largest growth in total milk produced. During the past 5 years (2011 to 2016), total milk production in Kansas has increased by 29%; the number of cows by 18%; and annual pounds of milk per cow by 1,785. Therefore, the Kansas dairy herd is not only growing, but is becoming more productive and efficient. At the end of 2016, Kansas ranked 13th nationally in milk yield per cow ...

Risk Factors For Occurrence Of Displaced Abomasum And Their Relation To Nutritional Management Of Holstein Dairy Cattle, Behlul Behluli, Arben Musliu, Kurtesh Sherifi, Curtis R. Youngs, Agim Rexhepi Jan 2017

Risk Factors For Occurrence Of Displaced Abomasum And Their Relation To Nutritional Management Of Holstein Dairy Cattle, Behlul Behluli, Arben Musliu, Kurtesh Sherifi, Curtis R. Youngs, Agim Rexhepi

The aim of the present study was to identify nutritional risk factors for the occurrence of displaced abomasum (DA) in Holstein dairy cattle raised in regions with highly variable nutritional management. Feeding program data were collected from 30 dairy farms throughout Kosovo via use of a standardized questionnaire, and an AgriNIRâ„¢ Analyser was used to analyze the nutrient composition of forage (hay, corn silage) fed to cattle on those farms. A diagnosis of DA was made via auscultation/percutation in the area of the last rib and hearing of a ping sound. Multivariate linear regression models were used to determine ...
