Dry matter intake, nitrogen intake, nitrogen digestibility, rumen ammonia-N and plasma urea-N concentration were measured in young rusa deer fed 4 diets containing 90 to 205 g/kg DM crude protein. The level of crude protein associated with maximal voluntary food intake and dry matter digestibility for these animals was found to be about 160 g/kg DM. Plasma urea-N was positively related to rumen...

Ileal digesta were collected via a post-valve-T-caecum cannula from piglets ( lo-15 kg) fed diets based on raw pea or on pea protein isolate (Finale or Frijaune variety). From the determined amino acids (AA) content of feed and digesta, AA apparent digestibility coefficients and proportions of proteins (endogenous, bacterial, dietary) theoretically present in digesta were calculated. Four essen...

Animal by-product meals have large variability in crude protein (CP) content and digestibility. In vivo digestibility procedures are precise but laborious, and in vitro methods could be an alternative to evaluate and classify these ingredients. The present study reports prediction equations to estimate the CP digestibility of meat and bone meal (MBM) and poultry by-product meal (PM) using the p...

The Protein Digestibility Corrected Amino Acid Score (PDCAAS) has been adopted for assessing protein quality in human foods since 1991, and the shortcomings of using the PDCAAS have been recognized since its adoption. The 2011 FAO Expert Consultation recognized that the Digestible Indispensable Amino Acid Score (DIAAS) was superior to the PDCAAS for determining protein quality. However, there w...

this experiment was carried out for a determination of metabolizable energy and the effect of the grind multienzyme on in-vitro dry matter and protein digestibility in diets, and as well on performance of broiler chicks. a number of 800 day old unsexed arbor acres broilers were placed in 8 treatments and 4 replicates (25 chicks each). a completely randomized design (crd) of a factorial arrangem...

This study evaluated the digestibility of leguminous protein labeled with 15N, by using nitrogen balance and quantitation of fecal endogenous nitrogen (FEN), determined by isotopic dilution, in order to correct apparent values. Seeds of common beans, cowpea and common pea labeled with 1.000 atoms% of 15N-excess were used as protein sources in diets for 60 male Wistar rats, during a 6-day assay....

this experiment was designed to evaluate the effect of phenolic components of scrophularia striata powder on feed intake, digestion and fermentation, rumination kinetic and rumen ecosystem in lori-bakhtiari sheep. in this experiment, 12 six months old lambs and average weight 30±1.5 kg were fed with 0 (control), 3 and 6 percent scrophularia striata for one month. feed intake, digestibility, rum...

the aim of this research was determination of nutritive value of cressa cretica with gas test method, in vivo digestibility and degradability with nylon bag method in three phenological stages. the amount of crude protein decreased significantly in seeding stage. but the amount of ndf and adf increased in seeding stage. the degradability of dry matter and rapid and slowly degradable fractions d...
