Our Top Picks
For most beef producers, the best protein tub is a self-fed supplement matched to the forage you actually have: a higher-protein tub suits dormant or low-quality winter grass, a moderate-protein tub with minerals suits cattle on decent pasture, and a lower-intake tub suits herds where overconsumption is a concern. Tubs from makers such as Purina, Sweetlix, Ridley Block and Cargill-branded lines differ in protein level, intake targets, mineral content and added ingredients, so the label and your herd’s needs should drive the choice. This guide explains how to compare them, with the caveat that feeding decisions are best confirmed with a livestock nutritionist or veterinarian.
At a Glance: Protein Tub Types
| Type | Best for | Typical stated features | Limits |
|---|---|---|---|
| High-protein tub (maker-labelled for dormant forage, e.g. Purina or Sweetlix range) | Winter range, poor-quality hay or stalks | Higher crude protein percentage, molasses-based, minerals included | Intake can run high if cattle are hungry or tubs are placed poorly |
| Moderate-protein tub with minerals | Cattle on fair to good pasture | Mid-range protein, vitamins and trace minerals | May not cover a large protein deficit |
| Low-moisture tub with intake limiters | Controlling consumption | Hard texture, designed for lower daily intake per head | Cattle may take time to start eating it |
| Tubs with added ionophore or fly control | Specific management goals | Feed additives as stated on the label | Requires vet or nutritionist guidance and strict label compliance |
| Tubs with NPN such as urea | Lower-cost protein | Non-protein nitrogen as part of the protein figure | Needs careful use; labels warn on adapting cattle and limiting intake |
| Block or poured-block supplements | Remote or low-labour feeding | Compressed or poured format, often similar nutrition | Hard weather and sizes may influence intake |
How to Choose a Protein Tub
Start with forage quality
Protein tubs are supplements, not a full ration. In dormant grass or low-quality hay, crude protein may fall short of what cows need, particularly in late gestation or lactation, and a tub can help bridge the gap. On lush pasture the need is lower and a mineral product might be enough. A forage test or a conversation with an extension agent or nutritionist is the best way to know the gap.

The feed tag lists guaranteed analysis, including minimum crude protein, maximum NPN equivalent, fat, fibre, calcium, phosphorus, salt and other nutrients, plus any medicated ingredients. Makers also state target intake per head per day. Compare tubs on the same basis, and note that products with a higher listed protein often come with a lower target intake.
Natural protein versus NPN
Some tubs get part of their protein from urea or another non-protein nitrogen source. Makers usually include warnings that cattle must be adapted and that tubs must be used as directed. Natural-protein formulations avoid some of those concerns but may cost more. Ask a nutritionist if either approach suits your herd.
Minerals and vitamins
Many tubs contain calcium, phosphorus, magnesium and trace minerals, and some are fortified with vitamins A, D and E. If your cattle already receive a free-choice mineral, check for overlap, as excess minerals or certain trace elements can be harmful. Selenium and copper needs differ by region and by what is in the forage and water.
Medicated or additive tubs
Some tubs include feed additives for fly control or to improve feed efficiency. Their use is regulated, labels carry specific directions, and some require a veterinary feed directive or a prescription depending on the region and product. Follow the label and consult your veterinarian.
Sizes and Handling
- Common tub sizes run from about 25 pounds for small tubs to 200 pounds for large ones. Pick a size that matches your herd so tubs do not sit open and spoil.
- Place tubs near water, shade or loafing areas, and spread them out so dominant cattle cannot monopolize them. A common recommendation is to provide enough tub space that all cattle can access one.
- Keep tubs off wet ground or use tub holders to reduce spoilage and limit tipping.
- Store unopened tubs dry, and discard feed that is mouldy or contaminated.
Safety Notes
Overconsumption of a high-protein or urea-containing supplement can cause health problems, so follow the maker’s intake range and watch consumption. Always provide fresh water, as high-protein supplements raise water needs. Do not feed tubs labelled for cattle to other species unless the label says so, because some ingredients are unsafe for horses, sheep and goats. If cattle show signs of illness, call your veterinarian. This guide is general information and not a feeding prescription.
Trade-offs by Budget Tier
- Budget: basic molasses-based tubs with higher NPN content. Lower cost per pound of protein, but need careful intake monitoring.
- Mid-range: name-brand tubs with balanced protein and minerals. Good for general winter and pasture support.
- Premium: natural-protein, fortified or medicated tubs for specific goals such as breeding or fly control. More expensive and often more regulated.
Pick X If… Decision Table
| Pick this | If you… |
|---|---|
| High-protein tub | are grazing dormant grass or feeding low-quality hay |
| Moderate-protein tub with minerals | are on fair pasture and want a mineral and protein top-up |
| Intake-limited tub | need to control per-head consumption |
| Natural-protein tub | prefer to avoid NPN, on advice from your nutritionist |
| Medicated or fly-control tub | have a vet-approved plan and will follow the label |
| Block supplement | feed in remote areas with limited labour |
Alternatives
- Range cubes or cake: hand-fed supplement offering controlled daily intake.
- Loose mineral plus higher-quality hay: can fix the gap if forage protein is only slightly short.
- Liquid feed supplements: used in some operations with proper feeders.
Reading Intake Targets and Feeding Setup
Makers print a target intake per head per day on the tag or product page, and this figure guides how many tubs you need and how often to replace them. If cattle eat much more than the target, the cause could be hunger, too few tubs, poor forage or a softer product. If they eat much less, they may not yet be used to the tub, the product may be unpalatable to the herd, or forage quality may be good enough that they do not need it. Introduce tubs gradually, place one near water or a loafing area, and check them often during the first week.
Seasonal Considerations
- Winter: cold weather and dormant forage raise protein and energy needs, particularly for cows in late gestation. Tubs can be an easy way to deliver extra protein where hay is limited.
- Spring and early summer: lush grass may be high in moisture and lower in some minerals. Consider a mineral-focused product on the advice of a nutritionist.
- Late summer: mature grass declines in protein, and tubs may be useful again.
- Wet weather: tubs can become sloppy. Use covers or holders and remove spoiled feed.
Storage and Waste Reduction
Keep tubs on a pallet or dry pad, away from standing water, and cover opened tubs when heavy rain is forecast. Remove empty or contaminated tubs promptly because cattle can chew on plastic, and dispose of used containers according to local rules. Buying only what the herd will use in a few weeks limits spoilage, and rotating stock so older tubs go out first helps keep the feed fresh and palatable.
Record Keeping
Track how many tubs go out, how quickly they are consumed and how the herd looks, including body condition and calf growth. These notes help you adjust placement and product selection from year to year, and they provide useful information for a veterinarian or nutritionist reviewing your program.
Frequently Asked Questions
How much protein should a cattle tub contain?
It depends on forage quality and cattle class. Tubs commonly range from low to high protein levels, and makers state intake targets accordingly. A forage test and a nutritionist can help match the tub to your herd.
How many tubs do I need for my herd?
Makers give a target intake per head per day, and the number of tubs should let all cattle eat without competition. Many producers spread tubs around the pasture and monitor how quickly they are consumed.
Can protein tubs replace hay?
No, they are supplements. They help cattle use low-quality forage by supplying protein and minerals, but cattle still need enough forage and fresh water.
Are tubs with urea safe?
They are widely used when directed on the label, but urea can be dangerous if cattle are not adapted or eat too much. Follow the maker’s instructions, monitor intake and talk to your veterinarian if unsure.
Why are my cattle eating tubs too fast?
Hunger, poor forage, insufficient tub spacing or a tub with a softer texture can raise intake. Check forage supply, move tubs, consider a hard or intake-limited product and consult a nutritionist.
Do I still need a mineral if I feed tubs?
Many tubs include minerals, but the amount varies. Read the tag, avoid doubling up without advice, and ask a nutritionist or veterinarian about regional deficiencies.
