True digestibility of the essential amino acids of partly dehulled and sunflower meal with hulls by balanced experiments with birds from Gallus species
Keywords:
amino acids, true digestibility, poultry, sunflower mealAbstract
Using adapted methods for balanced experiments with poultry, the true digestibility coefficients
of the essential amino acids of two of the most used plant protein sources – sunflower meal 25 (from
seeds with hulls) and 37 (from partly dehulled seeds) have been established. The true digestibility
coefficients by using of two methods – with intact and randomized (caecoectomized) birds have been
compared. The mean digestibility of sunflower meal 25 is lower by intact (83.95 ± 0.95 versus 88.34 ±
0.56 of sunflower meal 37), so as by randomized birds (88.16 ± 0.08. versus 89.55 ± 0.12 of sunflower
meal 37). The differences by lots are statistical significant (p ≤ 0.5) for both of the used methods. The
authors recommend updating of the data about the protein nutrition every of fodders in 5 years.
