Protein is usually the first figure producers notice on a cattle-feed label. It is important, but protein alone does not guarantee good growth.
Beef weaners also need enough dietary energy to maintain their bodies, stay active, and convert available nutrients into liveweight. Add suitable roughage, clean water, and balanced minerals, and you begin to see the whole nutritional picture.
Think of protein as the building material and energy as the crew doing the work. A truckload of timber will not build a set of yards by itself. You need both materials and power to get the job done.
Protein supports the growth and repair of body tissues, including muscle, organs, and the animal’s developing frame. It also provides nutrients used by rumen microbes, which help cattle break down feed and turn it into something the animal can use.
Young, recently weaned cattle generally require a better-quality diet than mature stock because they are still developing while adjusting to life without milk. Meat & Livestock Australia notes that calves below 150 kg require at least 15% crude protein for unrestricted growth. However, the right feeding program still depends on pasture quality, feed intake, and the animal’s target performance.
However, a high crude-protein percentage does not automatically make one feed better than another. Producers should also consider:
Basically, the label tells part of the story. The cattle and the complete diet tell the rest.
Energy fuels almost everything a weaner does, from walking to the water point and maintaining body temperature to depositing muscle and gaining weight.
Cattle obtain energy mainly by breaking down carbohydrates, fats, and, to a lesser degree, protein. Feed energy is commonly expressed as metabolisable energy, or MJ ME/kg. The amount required changes according to cattle weight, desired growth rate, activity, and environmental conditions.
When dietary energy is too low, cattle may use much of their available nutrition to maintain themselves. Growth can slow even when the diet appears to contain reasonable protein.
This becomes especially important as the pasture matures. Dry standing grass may look like there is plenty of feed in the paddock, but its digestibility and available energy can fall as the season progresses. FutureBeef explains that feed energy depends not only on how much energy is stored in the feed, but also on how easily cattle can digest it.
That is why judging a feeding program by protein percentage alone can be like checking the fuel gauge while ignoring whether the engine works.
| Nutritional factor | Main job | Practical consideration |
| Protein | Supports tissue growth and rumen microbes | More protein is not automatically better |
| Energy | Fuels maintenance and liveweight gain | Requirements increase with growth targets |
| Roughage | Supports normal rumen function | Provide suitable pasture, hay or chaff |
| Water | Supports intake and digestion | Keep it clean and consistently available |
| Minerals | Support normal body processes | Requirements vary with diet and country |
A practical weaner program starts by assessing the whole diet, not one nutrient
.
Look at cattle liveweight, pasture condition, available roughage, expected growth, and current feed intake. If animals have access to highly digestible green pasture, their supplementation needs may be different from weaners grazing mature dry feed. MLA advises that good-quality forage and appropriate supplements help keep the rumen active and support positive growth after weaning.
Introduce new grain-based feeds gradually and monitor:
The aim is not to chase the biggest number on the feed label. It is to create a balanced, practical program that cattle can consume consistently.

No. Adequate energy, roughage, minerals, water, and total feed intake must support protein. A high-protein ration can still produce disappointing results when cattle lack sufficient energy or do not consume enough feed.
Much of the diet may be used for maintenance rather than growth. Cattle may hold condition or gain weight slowly, depending on the size of the energy shortfall and the quality of the remaining diet.
Check the feed’s metabolisable energy, normally listed as MJ ME/kg, alongside crude protein, ingredients, and feeding directions. Compare products on the same dry-matter basis wherever possible.
Yes. Suitable pasture, hay, or chaff contributes fibre and supports rumen function. Grain-based supplementation should be introduced gradually and used according to the current product directions.
Maxi Weaner is a grain-based feed for beef weaners over 120 kg, designed to be fed with pasture, hay, or chaff. Its current specifications list 18% minimum crude protein and 12.0 MJ/kg minimum energy, combining both sides of the growth equation.
