evaluation of liquefied de-oiled herring silage in diets for growing pigs: feeding trials

Pens of pigs grown from 30 to 60 kg liveweight (LW) and 30 to 90 kg LW in separate experiments were fed diets containing either 75 or 150 kg t−1 dietary dry matter of de‐oiled herring offal silage stored for up to 8 weeks, and their performance compared with pens of pigs fed control diets based on soya bean meal formulated to contain equivalent levels of total lysine. All pens of pigs were rationed on the same time‐based scale of feeding. Pigs in both weight ranges fed herring silage diets grew significantly faster than the control pigs; in the 30–60 kg LW range growth rates were 687 and 529 g day−1 (P
