In an attempt to reduce costs, swine producers feeding newly weaned pigs frequently feed small amounts of complete pellets and transition them to grind and mix diets too soon.

A field study was conducted at a nursery in northwest Iowa to study the effects of feeding larger amounts of complete pellets to newly weaned pigs (Table 1).

Pigs fed greater amounts of complete pelleted feed grew faster and more efficiently. Even though total feed cost was higher, cost/lb of gain was lower.

In another nursery in NW Iowa, the following results were obtained (Table 2):

Grind & mix diets were made with corn, soybean meal, EcoSelect premix, Pig Booster 350, 60lb fat, and 5lb NEWtraStart™ Feed.  No medication.

Conclusion: Pigs fed larger amounts of complete pellets respond with greater gains and heavier weights out of the nursery.
