The Effect Of Regular Or Reduced-Fat Distillers Grains With Solubles On Rumen Methanogenesis And The Rumen Bacterial Community, E. Castillo-Lopez, C. J. R. Jenkins, N. D. Aluthge, W. Tom, P. J. Kononoff, S. C. Fernando
The Effect Of Regular Or Reduced-Fat Distillers Grains With Solubles On Rumen Methanogenesis And The Rumen Bacterial Community, E. Castillo-Lopez, C. J. R. Jenkins, N. D. Aluthge, W. Tom, P. J. Kononoff, S. C. Fernando
Department of Animal Science: Faculty Publications
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 …
Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson
Eradication Of The Liver Fluke In Dairy Cattle, Dave Muirson
Journal of the Department of Agriculture, Western Australia, Series 4
In July 1987, a meat inspector found liver fluke (Fasciola hepatica) in a cow at an export abattoir at Waroona. This was the first evidence of the liver fluke completing its life cycle in Western Australia. Fortunately, the Department of Agriculture is reasonably confident that a comprehensive drenching programme has eradicated the liver fluke. The establishment of liver fluke in the south-west coastal areas could cause a serious problem for cattle producers and the small number of sheep producers. Stock would need additional drenching, and if it was not carried out effectively production could be lost or stock could die. …
Relation Of Heart Girth To Weight In Holsteins And Jerseys, H. P. Davis, W. W. Swett, W. R. Harvey
Relation Of Heart Girth To Weight In Holsteins And Jerseys, H. P. Davis, W. W. Swett, W. R. Harvey
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Body weight is the one measurement most extensively used to evaluate growth, condition, and value for beef, and as a basis for calculating feed requirements for cattle. Weight can be determined readily by scales but unfortunately scales of a capacity adequate for weighing cattle are not always available. Thus there is a real need for a basis of estimating weight from some body measurement that can be obtained easily and at a minimum of cost and time. It is the aim of this study to utilize additional data now available to increase further the accuracy and reliability of estimating weight …
Carotene Content Of Native Nebraska Grasses, I. L. Hathaway, H. P. Davis, F. D. Keim
Carotene Content Of Native Nebraska Grasses, I. L. Hathaway, H. P. Davis, F. D. Keim
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The carotene content of twenty-four grasses native to Nebraska were determined at approximately monthly intervals from June to November. While the carotene concentration of most of the grasses was moderately high during the growing season, it declined to a rather low point by late November. With the exception of Switchgrass, Hairy Grama, Little Bluestem and Prairie Dropseed, all of the grasses contained enough carotene to supply the needs of range cattle until late November. However, only eighteen of the grasses still contained enough carotene by the latter part of September to furnish the carotene required by dairy cows. Even as …
