Apparent Faecal Digestibility of Essential Amino Acids from Ω3 Pufa Diets for Laying Hens

Abstract: The apparent faecal digestibility of the essential amino acids from Ω3 PUFA layer diets and feeding solutions to avoid possible adverse effects of such diets were investigated in two experiments conducted on Lohmann Brown laying hens. Experiment 1 used 72 layers assigned to three groups (C1, E1-1, E2), while experiment 2 used 96 layers assigned to four groups (C2, E1-2, E3, E4). All experimental diets have been enriched in Ω 3 PUFA by supplementing a conventional diet (C1, C2) with 5% flaxseed meal and 2% came… Show more

“…This result indicated that XP was effective in increasing the protein metabolizability of diets, possibly by reducing anti-nutritional factors (NSP) in corn and soybean meal. By hydrolyzing NSPs, xylanase allows the unavailable protein to be digested and amino acids to be absorbed, improving the MCCP (Varzaru, Panaite, Cornescu, & Olteanu, 2019). The metabolizability of proteins is directly influenced by the NSPs present in diets; therefore, by catalyzing dietary arabinoxylans, the enzyme allows amino acids, previously encapsulated in the cell walls of corn and soybean meal, to become readily available to perform the action of endogenous proteases, reducing endogenous production, which may be a secondary result of the xylanase response (Yaghobfar & Kalantar, 2017).…”
