Effects Of Supplementing Sources Of Zinc On Digestibility Parameters Of Beef Steers, Arminda Spikes James
Effects Of Supplementing Sources Of Zinc On Digestibility Parameters Of Beef Steers, Arminda Spikes James
Theses and Dissertations
Zinc (Zn) has numerous functions and life sustaining processes depend on the presence of Zn within the body. Zinc sulfate is a common form of Zn supplemented in the beef industry. Inorganic sulfate based minerals have been associated with negative rumen effects, mainly, decreased rumen fermentation and protozoa numbers. Our studies concluded no difference in digestibility of three different forms of Zn (zinc glycinate, zinc sulfate, and zinc hydroxychloride). Although overall digestibility did not change, there were specific mineral concentration differences after steers consumed concentrate treatment for 10 days. These differences implied that the mineral fed was consumed and absorbed …
Evaluation Of The Relationship Between Hair Coat Shedding Ability, Apparent Forage Digestibility, And Mineral Status In Angus Cattle, Margaret P. Loftin
Evaluation Of The Relationship Between Hair Coat Shedding Ability, Apparent Forage Digestibility, And Mineral Status In Angus Cattle, Margaret P. Loftin
Theses and Dissertations
The objective of this study was to evaluate the relationship between hair coat shedding ability, apparent forage digestibility, and mineral status in Angus cattle. Fecal samples were collected on fall calving Angus cows for one week in March, May, and July from 2019-2022. Liver and plasma samples were collected in March and July each year. Fecal samples were analyzed for DM, ash, NDF, and ADF while liver and plasma were analyzed for mineral concentration. Data were analyzed using MIXED procedure of SAS with significance declared at P0.05. Interactions were detected for DM, NDF, ADF, and liver Fe concentration. The model …
