Dressing Percentage: What You Actually Get Back
TL;DR: Dressed weight ÷ live weight × 100. It is the number that makes a live-weight price and a dressed price comparable, and without it you cannot tell which of two offers is better. It differs between commercial broilers and native birds, and it differs with how you dress — whether head, feet and giblets are counted. Measure it on your own stock, on several birds, and keep the method consistent between batches.
One weighing exercise, done once properly, and every pricing conversation afterwards gets easier.
The Calculation
Dressing percentage = (dressed weight ÷ live weight) × 100
To do it properly:
- Weigh the bird live, right before slaughter. After feed withdrawal, not before it — see how to dress a chicken.
- Dress it, in your normal way.
- Weigh the dressed carcass, in the form you actually sell.
- Divide, multiply by 100.
- Repeat on several birds and average. Individuals vary, and a single bird is not a measurement.
Write down what you counted. Head on or off, feet in or out, giblets in or out — each changes the number. A figure without that context cannot be compared to anything, including your own results next time.
Why It Matters More Than It Looks
It is the only honest way to compare prices.
A live-weight offer and a dressed price are not comparable numbers. To compare them, convert one:
- Dressed weight from live weight: live weight × dressing percentage.
- What a live price means per kilo dressed: live price ÷ dressing percentage.
Without doing that, a live offer will usually look cheaper than it is, because you are mentally comparing kilos that contain different things. Our dressed chicken prices and broiler prices guides cover the market side.
It tells you whether selling dressed is worth it. Selling dressed means you carry the processing labour, the equipment, the waste disposal and the weight loss. The price premium has to cover all four. Working out your own dressing percentage is the first step in finding out whether it does — see is poultry farming profitable.
Broilers and Native Birds Are Not the Same
Do not apply one figure to both.
| Commercial broiler | Native / free-range | |
|---|---|---|
| Selected for carcass yield | Yes, for decades | No |
| Body composition | Heavily muscled, especially breast | Leaner, more frame |
| Typical dressing percentage | Higher | Lower |
| Market price per kilo | Lower | Premium where recognised |
A native bird’s lower yield is not a fault — it is a different animal sold into a different market, and our broiler vs native vs layer guide compares the systems properly. But it does mean the arithmetic has to be done separately for each type you raise.
The same applies to colored slow-growing lines and upgraded natives, which sit between the two.
What Reduces Your Yield
Some of it is the bird. Some is you.
- A full crop and gut at slaughter. Feed withdrawal beforehand is the fix, and it also makes evisceration cleaner.
- Incomplete bleeding.
- Losses in processing — skin torn during scalding and plucking, flesh damaged during evisceration. Practice fixes most of this.
- Bruising from rough handling before slaughter. Catching and carrying birds badly costs you carcass quality as well as yield.
- Condition of the bird. A bird that has been ill, parasitised or underfed carries less. See internal parasites and how much feed does a chicken eat per day.
Use It Alongside Feed Conversion
Two numbers, and together they describe your meat operation:
- Feed conversion ratio — how much feed went in per kilo of live weight.
- Dressing percentage — how much of that live weight you actually sell.
Feed conversion tells you what the bird cost to grow. Dressing percentage tells you how much of it you can sell. Neither alone gives you cost per kilo of saleable meat; both together do.
That figure — cost per kilo sold — is the one that decides whether the enterprise works, and almost nobody calculates it. See when to harvest a broiler for the timing decision it feeds into.
The Honest Limits Here
The calculation and the factors affecting it are standard poultry practice. This guide quotes no dressing percentage figures, and that is deliberate: published values depend on the strain, the age, the dressing method and what is counted in the carcass, and a number applied to the wrong bird or the wrong method is worse than no number. Weigh several of your own birds, record what you counted, and use your own figure. If you are buying or selling on the basis of a percentage someone else quotes, ask them what their carcass included.

Frequently Asked Questions
What is dressing percentage?
Dressed carcass weight divided by live weight, expressed as a percentage. It tells you what share of the bird you actually sell or eat after processing.
How do I calculate it?
Weigh the bird live, weigh the dressed carcass, then divide dressed weight by live weight and multiply by 100. Do it on several birds and average, because individuals vary.
Why does dressing percentage matter?
Because it is the only way to compare a live-weight price with a dressed price. Without it you are comparing two different things and one of them will look cheaper than it is.
Do broilers and native chickens have the same dressing percentage?
No. Body composition differs, and commercial broilers are selected for carcass yield in a way native birds are not. Measure each type separately rather than applying one figure to both.
What is included in the dressed weight?
It depends on how you dress. Whether head, feet and giblets are counted changes the figure, so keep it consistent or your numbers will not compare between batches.
What reduces dressing percentage?
A full crop and gut at slaughter, poor bleeding, and losses during processing. Feed withdrawal beforehand and careful handling both help.
Should I quote customers in live weight or dressed weight?
Whichever you use, be consistent and be clear which one it is. Most disputes over price come from one side quoting live and the other assuming dressed.
