New Experiments

Juliana Ravagnani started two experiments: "Human milk oligosaccharide-dependent engraftment of Bifidobacterium infantis (Bi) in pigs", and "Determination of digestible indispensable amino acid score (DIAAS) for salmon proteins".

Minoy Cristobal started two experiments as well: ''Effect of feeding intact protein from soybean meal instead of crystalline amino acids on growth performance, protein synthesis, and immune system of growing pigs'', and ''Effect of feeding intact protein from soybean meal instead of crystalline amino acids on energy and nitrogen balance of growing pigs''.
