Currently, highly fluctuating ingredient prices that influence pig feed cost are encouraging swine producers to evaluate their feeding programs.
The worst parameter that can be used in feeding program evaluation is feed cost per ton, which does not account for the effects on pig growth performance. A good parameter that can be used in the evaluation is cost of feed per pound of gain. Therefore, any improvement in pig feed conversion can be considered as an opportunity to fight the increasing feed prices.
In order to optimize pig feed conversion (F/G), it is important to recognize the factors that can affect it and their effects (potential to increase or decrease F/G). The following factors can have a significant influence on F/G.
It is important that producers identify the management practices that can help them optimize feed conversion while maximizing profitability. Efficient feeder management and biosecurity practices can have dramatic effects on improving feed conversion. This includes rodent control (see factors 1 to 13). Manipulation of nutrient levels in the diet needs to be oriented to match pig nutrient requirements, and to improve pig nutrient utilization (see factors 14 to 19).
