Abstract
Salmon protein hydrolysates (SPH) from two different rest raw
materials were evaluated in diets for weaning piglets. Four experimental
diets were included in the study: a diet based on plant
protein with soy protein as the main protein source (Diet PP), a
diet based on fishmeal in exchange for soy protein (Diet FM) and
two diets in which different SPH replaced fishmeal in the FM diet.
The experimental diets were fed to piglets from the day of weaning
until 32 d postweaning. In addition to the record of performance
data, an intestinal sampling for mucosal morphometry and
microbiota 16S rRNA gene sequencing were performed at day 11
on a subset of the animals. The duodenal villi absorption area was
significantly larger in piglets receiving Diets SPH compared with
Diet PP (p < 0.02). A significant positive correlation between
duodenal villi height and average daily gain during the first 11 d
postweaning was detected. Only small differences in intestinal
microbiota community and no differences in growth performance
were detected between the experimental diets. To conclude, SPH
seem to be an interesting novel protein source in weanling piglets.
