The Cost of Raising Pigs Most Farmers Donβt Calculate
Most farmers calculate the cost of feed, medication, labour, water and other expenses when calculating how much it costs to raise their pigs.
But there is another cost that many farmers don't pay enough attention to:
The cost of keeping a pig for too long.
Let me give you a simple example.
Imagine you have a pig that has reached 100kg, and your market is willing to pay a good price for it at that weight.
But you decide to keep feeding it until 180kg because you believe that more weight means more profit.
Here's where things can get interesting.
Let's say, just for this example, that from 20kg to 100kg, the pig requires around 2.5β3kg of feed to gain 1kg.
That means gaining another 10kg may require roughly 25β30kg of feed.
But now the pig has reached 100kg and you're trying to push it to 180kg.
As pigs become heavier, feed efficiency can decline.
So let's say the pig now requires around 3.5β4kg of feed to gain 1kg.
To gain another 10kg, it may now require roughly 35β40kg of feed.
Do you see what is happening?
The pig is still growing, but each additional kilogram can become more expensive to produce.
And you're not only paying for the extra feed.
You're also paying for the additional water, medication, labour, housing and other costs during those extra weeks.
Now imagine the pig was worth β¦250,000 at 100kg.
You keep it until 180kg and sell it for β¦450,000.
At first, it looks like you made an extra β¦200,000.
But what if the additional feed and other costs of producing those extra 80kg came to β¦180,000?
Your extra profit is only β¦20,000.
And if those additional costs came to β¦220,000, you've actually lost β¦20,000 by keeping the pig longer.
This is why a heavier pig is not automatically a more profitable pig.
There can be a point where keeping a pig longer still makes it heavier, but the cost of producing those extra kilograms is eating into your profit.
The exact point will be different from farm to farm because feed prices, genetics, growth rate and market prices are different.
So before keeping a pig longer just because you want it to become bigger, don't only ask:
βHow much more will I sell it for?β
Also ask:
βHow much will it cost me to produce the extra weight?β
Because sometimes, the extra weight you're trying to produce is costing you more than the extra money you're going to receive for it.
And that's a cost many farmers don't calculate.
