Troubleshooting problems with the feed conversion ratio
Feed represents approximately 60% of the costs in pig production. It is therefore very important to have a good feed conversion ratio.

06-Sep-2022niels.wuytsDear Dr. Marco,
FCR is a crucial parameter indeed to maximise production efficiency of pigs. Hence my continious surprise that so little is talked about the one parameter that can immediately improve FCR by an average of 10%. No other single parameter that can do that. I'm sure you guessed that I am talking about leaving the boars entire. How expensive does feed have to become before we finally realise we can not afford to rob the male pig from his single largest anabolic tool for optimal growth efficiency, its testicles?
Kind regards,
Niels

Increased feed conversion ratio, stable mortality. What about growth?
To determine the causes of the increase in the feed conversion ratio of pigs, we must start by asking whether mortality has also increased.

The feed conversion ratio and mortality are elevated. What about growth?
To determine the causes of the increase in our feed conversion ratio, we must begin by asking ourselves whether mortality has also increased.

A high feed conversion ratio and what about mortality?
If my farm's feed conversion ratio is up, the first thing I have to look at is how mortality is doing.

Anestrus in multiparous sows
When multiparous sows are affected, not as many need to be culled as in the case of gilts (which we saw in the last article). Generally sows will eventually show signs of heat, but with a considerable delay compared to a normal heat.
