Effect of Presence of Fish Meal in Unmedicated Diets on Early-Weaned Pigs

Source: Animal Production

In two experiments, with pigs from 3 or 5 weeks of age, high nutrient dense diets (HND) or conventional diet (CONV) were given with or without fish meal up to slaughter. Diets were unmedicated.

In experiment 1, in the first 56 days, inclusion of fish meal in the CONV and HND diets significantly improved growth rate but food conversion efficiency was significantly improved in the CONV diet only.
