Formerfood products (FFPs) have a great potential to replace conventional feed ingredients.
This study aimed to investigate the possibility to partially replace standard ingredients with two
different types of FFPs: bakery (FFPs‐B) or confectionary (FFPs‐C) FFPs and their effects on growth
performances, feed digestibility and metabolic status in post‐weaning piglets. Thirty‐six post‐weaning
piglets were randomly assigned to three experimental diets (n = 12 per diet) for 42 days: a standard
diet (CTR), a diet where 30% of standard ingredients were replaced by confectionary FFPs (FFPs‐C)
and a diet where 30% of standard ingredients were replaced by bakery FFPs (FFPs‐B). Individual body
weight and fecal dry matter were measured weekly. Feed intake (FI) was determined daily. Average
daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were calculated.
Fecal samples were collected daily for three days/week to determine apparent total tract digestibility
of dry matter (ATTD). At day 0, 21 and 42, blood samples were collected from all the piglets. No
significant differences (p > 0.05) between groups were found in growth performances and metabolic
profile. However, ATTD in FFPs‐B group was lower (p < 0.05) compared to the CTR group at the end
of the experiment. This study confirmed the possibility to formulate homogeneous diets integrated
with 30% of both categories of FFPs. Further investigations are needed to clarify the effects of bakery
former food products on the digestibility of the diet.
