A bird can look ready and still sit inside its withdrawal window. Here is how to read labels, time the fast and keep records.

A broiler can look perfect on sale morning. Full breast, clean feathers, a good weight on the scale. None of that tells the buyer whether the medicine you gave three weeks earlier has cleared the bird. That gap is what the withdrawal period is for, and it is the part of selling most growers learn last, usually when a buyer asks the question at the gate.
This guide covers what withdrawal means on a broiler farm, where the medicine comes in, how to read a label, what feed withdrawal before the catch involves, and how to keep a record that holds up when someone asks for it. It is written for growers selling to chop bars, market traders, caterers and neighbours. The periods themselves are not ours to set. Your vet and the relevant authority set them, and where a number matters we tell you to confirm it rather than guess.
Hold on to one rule from the start: the withdrawal period belongs to the product and the route you used, not to the chicken. Two products given on the same day can carry different periods, so treat each one on its own line.
A withdrawal period is the time that must pass between the last dose of a medicine and the point when the bird can be slaughtered and sold for meat. Some medicines leave traces in the flesh, and the body clears them over time. The label, or the vet's instruction, gives you the time. You do not sell until it has run out.
The bird's condition tells you nothing about this. A bird can look completely well on the third day after a course and still be inside its window. Good appetite and a clean crop show that the bird is recovering. They do not show that the medicine has left the meat. That gap between how a bird looks and what the record says is where most sale mistakes happen.
Withdrawal rules for eggs are a separate matter. If you also keep layers, check the egg side against the product labels on its own. This guide is about broilers.
Medicine reaches a broiler in three common ways, and each one needs its own line in your records:
Most farms use a mix of these over a season. A flock may start on medicated feed, move to a water course when a problem shows, and then go back to plain feed. Each treatment starts its own count, and a new course restarts it. The record has to show every change, not just the first one.
Most withdrawal mistakes start with a label nobody read properly. Go through it in this order before the product goes into the house:
Some packs from roadside sellers are faded, half in a language you do not read, or missing the leaflet altogether. Do not use a product you cannot read. Buy from a shop that will show you the full leaflet, and keep the leaflet with the pack until the flock is sold.
Growers often mix up feed withdrawal with drug withdrawal, so it is worth separating them. Feed withdrawal means taking the feed away for a short, set period before the birds are caught and slaughtered. The reason is practical. A bird with a full crop and a full gut is harder to dress cleanly, and gut contents are a route for contamination of the carcass. Letting the gut empty first keeps the process cleaner.
Feed withdrawal does not replace a drug withdrawal period. A bird can have had its feed taken away and still carry a residue from a medicine given days earlier. Both checks apply, and they are counted separately.
The length of the fast is set by your buyer or processor and by local practice, not by us. Ask before the catch day, and write the answer into the house book. Water stays available throughout. Taking water away to make birds lighter causes stress, and the losses it brings cost you far more than the feed you save.
Put the fast on the timetable. If birds are caught in the morning, decide the evening before when the feed comes away, and tell whoever does the early shift. A fast that starts at a different time each day is how birds reach the catch with full crops.
Before the first bird is caught, go through the flock against this list. It is not a permit. It is the sequence we would walk through with you before any sale.
| Check | What you are looking for | Who confirms it |
|---|---|---|
| Every medicine used in the flock | Product name, route, batch and the date of the last dose | Your own treatment record, checked against the packs |
| Withdrawal period on each label | A stated period counted from the last dose, for that product and route | The label first, then your vet if it is unclear |
| Feed changes in the last weeks | Whether any medicated feed was used, and the date the flock moved to plain feed | The feed bags and your feed record |
| Sick or treated birds | Any bird given treatment, or culled, inside the window | Your vet, before any of them go in a sale |
| Feed withdrawal before the catch | A set, short fast with water kept on, timed to the catch | Your buyer or processor |
| The earliest sale date | The last withdrawal end date written as a calendar date, with no sale before it | Your calendar, checked a second time against the record |
If any line in that table is blank, the flock is not ready to sell, whatever the birds look like on the day.
Write it down every time, in the same place. A medicine entry needs five things: the date given, the product name and batch, the route, the number of birds treated, and the date the withdrawal period ends. The last one is the entry people forget. Write it as a calendar date, not as a count of days, so the sale plan can be checked against it without arithmetic on a busy morning. "Earliest sale on the 20th" is easier to act on than a number of days you have to add up yourself.
Keep the record with the medicine packs or in the house book, not in your head. A buyer who asks in the middle of a busy week will want to see it. So will a vet who is called in an emergency and needs to know what was given first.
Read the record once a week. Check that every entry has an end date, that each end date is on the sale calendar, and that nothing in the house has been used outside its label. A short check on a fixed day beats a rushed search on the morning of the catch.
Chop bar owners and market traders buy by the bird, and most of them will not test anything. They trust the grower, and sometimes they trust the look of the bird more than they should. That trust puts the responsibility on you, not on the buyer.
Festive weeks make the pressure worse. Christmas and Sallah bring a rush of orders, and the temptation is to bring a sale forward by a few days to meet the price. Do not. A bird sold inside its withdrawal window is a risk to whoever eats it, and it is a painful thing to explain later. If the demand is there, set the sale date from the start so the withdrawal end falls before the rush. Do not plan to squeeze the flock in after it.
The same goes for sick birds. A flock that has been treated should not be sold to clear space or to cover a loss. Keep treated birds back until the withdrawal has run out and your vet has agreed they are fit to go.
There are three situations where you stop and ask before selling anything:
In each case, hold the birds. Call your vet, or the district veterinary officer if you can reach one, and ask for the withdrawal period for that exact product, route and dose. If you need an official answer, the Veterinary Services Directorate is the body to ask. We will not give you a withdrawal number from memory. A wrong figure in this area reaches people who never saw the farm.
Our chicks leave the hatchery vaccinated, and we tell you what was given. That vaccine record is useful for your disease history, but it is not a treatment record. Keep the two in separate columns of your book.
Most of these are small lapses on a busy day. The fix is the same for each one: write it down when it happens, and check it before the catch.
No. Feed withdrawal is a short fast before the catch, set by your buyer or processor, so the gut is emptied before the birds are dressed. The medicine withdrawal period is a separate count, set by the product label or your vet. Both have to be met.
Not on appearance alone. Find the withdrawal period for each product the flock received, count from the last dose on the right route, and check the end date on your calendar. If that date has not passed, the bird is not ready to sell, however healthy it looks.
Do not use it on birds you plan to sell until you can read the full label. Take the pack to your vet, or to a reputable agro-vet shop that can show you the leaflet. If you have already used it, treat the flock as unsold until you have an answer.
The product label gives the manufacturer's period for that product and route, and your vet applies it to your flock. When the label is unclear or you combined products, the vet makes the call. For an official answer, ask the Veterinary Services Directorate.
A clean sale starts long before the catch. Plan the treatment dates, any feed change and the withdrawal end date while the chicks are still in the brooder, not in the last week. Once you have rough dates, our broiler day-old chicks give you Ross 308 and Cobb 500 to plan around, and the price page shows current from-prices. Confirm the figures with us before you budget, because they move.

A weekly weighing routine for broiler farmers: how to pick an honest sample, the weights to compare against from day 7 to day 42, the average and uniformity sums, and what to do when the flock is behind.
Feed cost per kilo of broiler depends on how much feed each kilo takes and what you pay for it. These ten habits lower both without starving the birds or buying additives.
Heat kills the heaviest broilers in the last days before sale. This guide explains why, shows the signs in order, and sets out the house, stocking, water and feeding changes that prevent it, plus an afternoon emergency plan.
