The study addresses the utilization of food waste by-products from faba bean (Vicia faba L.) pods (FBP) as an alternative feed supplement to promote sustainable piglet growth by reducing antimicrobial use. Objectives include evaluation of FBP in terms of nutritional components (proximate composition, fibres, minerals), phytochemical composition (total phenols, HPLC-MS profiling), and in vitro biological activities.

Methionine (Met) is a popular nutritional supplement in humans and animals. It is routinely supplemented to pigs as L-Met, DL-Met, or DL-2-hydroxy-4-(methylthio) butanoic acid (DL-HMTBA). We investigated the effect of these Met supplements on jejunal amino acid (AA) transport in male castrated Piétrain × Danbred pigs, also including a non-supplemented group.

Article Synopsis
  • - The study investigated how different diets (hay vs. sugar beet pulp) and grinding sizes (fine vs. coarse) during sow gestation and lactation affect stress and immune markers in both sows and their piglets, as well as the impact of weaning age (conventional vs. late).
  • - Salivary markers such as chromogranin A (CgA), alpha-amylase, and oxytocin were notably influenced by diet and weaning age, with specific increases observed in sows and piglets fed certain types of fiber at various weaning stages.
  • - Overall, the findings indicate that dietary fiber type, weaning age, and grinding size significantly influence stress and immune responses in pigs,

This study aimed to determine the effects of spray dried plasma (SDP) on growth performance, carcass traits, tibia quality, and hemagglutination inhibition titers in broilers fed two nutritional strategies with high or low nutrient density. In the study, 816 one-day-old Ross 308 male broiler chickens were divided into a 2 × 2 factorial arrangements consisting of four treatment groups with 12 replicates (17 birds/replicate) based on diets with high nutrient density (HND) or low nutrient density (LND) from d 0 to 42 and receiving either control or 1% SDP diets during d 0 to 10. The results showed that feed intake (FI) and body weight gain (BWG) were increased (P < 0.
