Uses Of Genomic Predictions In Commercial Beef Cattle Operations, Matt Miller
Uses Of Genomic Predictions In Commercial Beef Cattle Operations, Matt Miller
Dairy Science
This paper aimed to achieve two different objectives. The first objective of this study was to identify and explain the genetic gain achieved in commercial beef cattle operations with the use of genomic predictions versus the use of visual appraisal and EPDs. The second goal of this paper was to develop a method to easily explain genomic predictions and their practical applications on commercial beef operations to a lay audience, specifically to ranchers. In order to accomplish these objectives, I evaluated three of the most common selection methods used by producers today. These included visual appraisal, expected progeny differences (EPDs), …
The Effect Of Amylase Supplementation With Low-Starch Rations: Effects On Milk Production And Feed Consumption, Alfred Eaton
The Effect Of Amylase Supplementation With Low-Starch Rations: Effects On Milk Production And Feed Consumption, Alfred Eaton
Dairy Science
The objective of this trial was to determine if there was an increase in milk production or a decrease in feed consumption by dairy cattle when fed an exogenous rumen-resistant amylase, named RumiStar. High feed prices have caused dairymen to look for new ways to be more efficient. Commercial feed additives have been proposed as opportunities to improve efficiency. In our study a minimum of eighty multiparous Holstein cows were assigned to each of two pens, with a minimum of forty cows in each. Cows that completed their lactation during the study period were replaced with fresh cows to keep …
