Financial impact of PRRS in weaners

In a study by Polson (37) the financial impact of PRRS in sucking pigs (weaners) was evaluated using a partial budget model.

The basic cost assumptions are shown below. In Table 2, the impact of PRRSV infection and secondary agents in the sucking pigs (weaners) for a farrow-to-feeder farm are shown. The difference between affected and non-affected pigs ranged from US$0.73-18.21, depending on the changes in mortality and average daily gain.

Basic cost assumptions

1. Baseline ADG = 363 gm/hd/day
2. Baseline FCR = 1.75 kg feed/kg body weight gain
3. Weight into nursery = 5.45 kg/hd
4. Days on feed = 42 days
5. Down-time/turn = 2 days
6. Non-feed variable costs/pig = $ 1.00/pig
7. Nursery feed cost/ton = $ 220/ton
8. Sale price/kg = $ 2.09/kg
