Teat or open bucket? How to choose a calf feeding bucket
, by Michael van Wassem, 3 min reading time
A calf wants to suck. Read when a bucket or bottle with a teat is the better choice, how to pick the right teat and how to keep everything hygienic.
A calf does not simply drink milk: it wants to suck. That is why the choice between an open bucket, a bucket with a teat or a bottle is about more than convenience. This buying guide helps you choose, whether you have a single calf or a whole group.
Short answer: teat or open bucket?
💡 In short: for most calves, a bucket or bottle with a teat suits better than an open bucket, because the calf can then suck the way it naturally does. An open bucket is easier to clean but offers no sucking moment. What suits your farm is best discussed with your vet or feed adviser.
Why sucking matters
Young calves have a strong need to suck. When a calf sucks, a kind of groove in the oesophagus (the oesophageal groove) closes, so the milk goes straight to the abomasum. When slurping from an open bucket this is less certain. A teat therefore supports natural drinking behaviour. Sucking is also a matter of welfare: calves that cannot suck enough sometimes start sucking on other calves or on objects.
The options side by side
| Type | Useful for | Watch out for |
|---|---|---|
| Open bucket | Simple, easy to clean | No sucking moment; the calf has to slurp from the bucket |
| Bucket with teat (round or with two flat sides) | Several calves, hanging on a fence or pen wall | Check the teat and coupling regularly |
| Floating teat | Drinking from an open bucket without a teat in the wall | Clean thoroughly, including the small tube |
| Bottle with teat (1 to 2.5 litres) | A single or weak calf; you see exactly how much it drinks | More manual work with larger groups |
| Feeder with soft teat (2.5 or 4 litres) | Controlled feeding with a large opening | Check the size and type of teat |
How to choose the right teat
Teats differ in length (for example 100 or 125 mm), colour and firmness. With many manufacturers, the colour says something about the firmness or the size of the opening. When reordering, choose the same variant your calves are used to and follow the manufacturer's description. A softer teat is easier to drink from, a firmer one slows down a greedy calf. Replace a teat as soon as it cracks, goes soft or the hole gets bigger.
Our calf rearing products and calf milk and bucket products are not available in the UK, so there are no links here. Ask your vet or local supplier for advice.
Hygiene: keeping buckets and teats clean
Milk residue is a good breeding ground for bacteria. Rinse buckets, bottles and teats after every feed and let them dry well. A bottle brush helps with rims and threads. Hygiene is an important point of attention but no guarantee. If a calf has diarrhoea, a fever or is not drinking, call your vet.
Common mistakes
- Keeping on using a teat that is already cracking.
- Having no spare teats at home.
- Hanging a bucket that is not secure or does not suit the size of the calf.
- Fitting a teat of a different size without checking it fits.
- Swapping buckets between calves without cleaning in between.
Checklist before you buy
- How many calves do you feed at the same time?
- Will you hang the bucket on a fence, or use a bottle?
- Which teat size and firmness suits your bucket or feeder?
- Do you have spare teats and a bottle brush?
- Can you rinse everything after each feed and let it dry?
Frequently asked questions
Is an open bucket prohibited?
I do not give a legal opinion on this. Check the current rules with the relevant authority and talk to your vet.
How often should I replace a teat?
As soon as it cracks, goes soft or the hole has become larger. Keep a few spare teats at hand.
Does every teat fit every bucket?
Not always. Choose the same size as your current teat and check the fitting.
What is a floating teat?
A teat that floats on the milk and draws it up through a small tube. This lets a calf drink from an open bucket too.
Summary
A teat matches the natural sucking of a calf. Choose the bucket or bottle that suits the number of calves, pay attention to teat size and firmness, keep spare teats ready and rinse everything after each feed. In case of illness or doubt, involve your vet.
