Cow-Calf Certification Practice Exam

How long before turning cows out on corn stalks should they be adapted to grain to minimize digestive issues?

1. 5-7 days

2. 10-14 days

3. 2-3 weeks

4. 1 month

The correct answer is: 10-14 days

To minimize digestive issues when turning cows out on corn stalks, it is recommended that they be adapted to grain for a period of 10-14 days. This timeframe is crucial because it allows the rumen microbes to adjust to the changes in diet, particularly when transitioning to a higher starch content typically found in corn stalks. A gradual adaptation reduces the risk of acidosis and other digestive upset that can occur if ruminants suddenly encounter a diet they are not accustomed to. During the adaptation period, cattle gradually receive increasing amounts of grain, which helps them build the necessary microbial population and enzymatic activity in their rumen to effectively digest the higher starch content present in corn stalks. This careful introduction is key for ensuring digestive health and overall well-being. Options outside of this 10-14 day range may not provide adequate time for the necessary microbial adaptations to occur, leading to higher risks of digestive disturbances.
