Understanding the crucial task of ensuring a calf has nursed properly is fundamental in their early development. In this comprehensive guide, we will explore the essential steps to verify if a calf has nursed, empowering you to confidently care for these newborn calves.
Step 1: Observe the Calf
Witnessing the event is the only way to be absolutely sure a calf has nursed is to see it with the teat in its mouth.The initial step in verifying if a calf has nursed successfully is observation. After the calf has fed, take a moment to watch its behavior. A well-fed calf will display signs of contentment, such as a relaxed posture and sometimes even a nap. On the contrary, a hungry calf may remain restless and vocalize its hunger. A calf that is not getting enough milk may also move from teat to teat seeming to never quite get satisfied.
Step 2: Check the Udder
Examine the mother cow's udder. A calf that has fed well will leave the udder appearing less swollen or less full. The udder should feel softer post-nursing as the calf has ingested milk, resulting in a reduction in its size. This visible alteration in the udder serves as a good sign that the calf has nursed efficiently. One or more of the cow's teats will be visibly smaller after the calf has nursed. You may also notice wet or curled hair around the teats, and shiny teats.
Step 3: Assess the Calf's Appearance
A calf that has nursed will have a palpably enlarged stomach. It will also have passed its first dark, slimy bowel movement, also known as meconium. If the calf's bowel movement is a dark orange or golden color, it means its getting colostrum. After just a few days of nursing the calf's bowel movements will be a bright yellow and softly formed. A watery bowel movement is a sign of scours, and could mean that the calf did not get good passive transfer.
Step 4: Assess the Calf's Behavior
Another method to verify if a calf has nursed is by observing how it interacts with its surroundings post-feeding. A content calf will often engage in grooming behaviors, interact with other calves, or exhibit a general sense of calm. Conversely, a calf that has not nursed adequately may continue to display signs of hunger or restlessness. They may go from teat to teat searching for milk if a cow doesn't have enough milk. They also may be lethargic and you may find them laying in the exact same spot from earlier in the day.
Step 5: Consult Your Vet
If you are still unsure if your newborn calf is nursing you can consult your vet and request blood tests. A calf's serum protein levels can be measured between 1 and 5 days of age to determine if it received enough colostrum.
Got Milk: How to Verify If a Calf Has Nursed
In conclusion, verify if a calf has nursed by following these simple yet effective steps, you can confidently determine whether a calf has nursed or not. If a calf hasn't nursed, it should be given colostrum as soon as possible. Ideally, colostrum should be given within the first two hours of birth, and repeated within within six hours. If a calf is weak, it may need to be tube fed colostrum.
