How to Increase the Body Weight of Broilers

This post was last updated on 16 February, 2019

Consumers want to buy broiler chickens with big weights, and some are ready to go with the price you are willing to sell them when they are impressed with the broilers’ weight. This is why poultry farmers are always looking for ways to increase the body weight of their broiler chickens.

As a poultry farmer, I’m sure you’re having a number of broiler chickens you are raising to sell during festive periods such as Christmas, Easter, Sallah etc. However, you’re worried about something. Some or all your broilers are not growing as expected and they have not attained the expected market weight. I understand your worries and how you are feeling right now. It is not easy raising broilers for over 2 months (as the case may be) but all looks as if nothing has been done. It kills one’s morale and set fear in one’s mind.

How to increase the body weight of broilers

The truth is that, if your broilers do not grow bigger or have good body weights, then don’t expect much profit or have it at the back of your mind that you run at a loss. Nevertheless, you can still do something to increase your broilers’ live body weight or make your broiler chicken grow bigger. This post would explain how to make broilers add more weight without incurring additional cost. Here are five (5) ways to increase broiler weight:

1. Sort broilers according to their sizes and weights

The first thing you need to do is that you should sort your broilers that have similar body size or weight together, and keep them in the same growing pen. This will eliminate the factor of inequality. In addition, they will be able to feed well without being intimidated or cheated by the bigger or weightier broilers. You can increase the quantity of finisher feeds given to the group with lower weights. When you do this, you will surely see a difference.

2. Formulate and give them an excellent broiler feed

Another way to make your broilers grow bigger or have a higher weight is by producing and feeding them with an excellent feed. I have decided to share my special broiler diet formula which includes both starter and finisher diet. Click here for details.

3. Use broiler growth promoter or enhancer

I don’t usually support farmers using growth enhancers for their animals. They could be harmful to your animals in one way or the other. However, if you must use it, try and research on them and consult your veterinarian. If you must use any broiler growth enhancer, try as much as possible to use plant-based broiler growth promoter or enhancer.

4. Avoid starving your broiler chickens

I have visited the farms of friends and family, and even that of clients. Some of them starve their chickens in the name of no money to raise them again. In the first place, why should you commit yourself into what you won’t finish? So don’t expect any miracle if you are not giving your broilers the required quantity of feed they need to feed on. If you feed your chickens well, they will grow bigger and attract more market prices. Though, there are cases where broilers don’t grow well, irrespective of the quality and quantity of feed given to them. The major reason for this is related to the broilers’ genetic foundation. So ensure you purchase a good broiler breed from a reputable farm or hatchery if you want to raise broilers for commercial purpose.

5. Procure quality broiler chicks from reputable sources

No matter what you do or give broilers that came from a poorly performing parent stock or hatchery, they may never do well in terms of adding more weight or grow bigger. Genes have a lot to do with animals’ growth and performing. This is the reason why you must procure your broiler chicks from a reputable hatchery with excellent records. You can ask other poultry farmers around you about the hatchery or vendors they procure chicks from.

  1. Helo sire…
    I need suggestions on growth promoter/boosters and somthing to make them have weight on my 5 weeks broilers……the are very small compared to the previous ones which I started selling from 5 weeks. Please help,thanku

    1. For promoters and boosters, please consult a veterinarian. However, for increased weight for your birds, give them a balanced finisher and let them have access to sufficient water. You can sort them according to their weight and feed each group separately.

  2. My broilers have contracted AI and 200 die everyday they r 40 days old today but their avg weight is 1.5 kg, what do u suggest i do , can i shift them in different shed so they gain weight

    1. Avian influenza is highly pathogenic. I will advise that you seek the help of a veterinarian to be sure of the strain that has infected your birds. If it is confirmed that some have not been infected (which I doubt), cull them immediately to avert further disaster. Please, you must consult a qualified veterinarian in this situation. He/she would be in the best position to assist you.

    2. i would kill them all, burn the bodies, clean you coop (walls and ceilings included) with a disinfectant from the vet to get rid of such diseases and start fresh again. AI is not something you want to experience again and it is definitely something you want to sell to ur customers.

  3. I’m so interested in ur article sir
    I have these questions,pls help me.
    1-what can u do for ur birds to have big/large chests
    2-what can one do naturally to obtain fast growth in size

    1. 1. If you mean broilers, you have to feed them well. Use a good broiler feed formula and your stocking density should not high. Overstocking/overcrowding affects the growth rate of broilers.

      2. Hmmm. Natural way is to procure birds from a reputable hatchery/source and ensure that their genetic background (parent stock) are good. Feed the birds with a balanced ration and don’t overstock. You will surely see your birds growing fast if all these conditions have been met.


  4. Hello sir,
    Thanks for this article, very nice, my birds are 3 weeks now. What size do you think they should weight now. As I intend to sell them when they are 6 weeks and we aim for 2kg. Do you think they should weight at least 1kg now? So I know if I’m on the right track or not. Thanks for your help

    1. They should be having an average weight of 800g (males) and 600g (females). The best way to find out is to use a weighing scale.


    1. This is a sign of maturity and most importantly, it shows the birds want to grow new feathers. It’s a natural process.

    1. The answer to this question is commonly subjective. But all things equal, the weight should be around 3 kg.

  5. Thank you Akinbobola for this formula. I bought and used them for my broilers that I raised for last Easter. Seriously, I couldn’t believe my eyes. The birds were weighting averagely 2.8kg and 3.6kg in 6 weeks and 8 weeks respectively. You’re indeed a God sent. Thank you! Do you have any special formula for layers. Kindly let me know.

  6. What formula is it that can make my birds gain weight, my birds are 3mnth 3wks yet they don’t weigh rea please

  7. Hello, am having issues with the market women here in Bayelsa State as they only look forward to buying 3 months old birds which I feel is too long a period for broilers. The annoying thing is they come pricing 1500/1800 for a bird kept that long. What solution do you think is best to maximise my profit as am considering adding maize to the feeds bought, besides how long am I to stay on Starter considering am keeping them 3 months?

    1. Don’t add maize, else you will alter the nutritional value of the feed. And regarding the duration of starter, you should give starter for 4 weeks. Give finisher until you slaughter at the 12th week.
