Twenty seven cecectomized mature Single Comb White Leghorn cockerels were used to eslimate true animo acid digestibilities (TAAD) coefticients for eight feedstuffs for cecectomized roosters. The objective of this paper was lo evaluate altemative feed ingredients TAAD coefficients using a standard precision fed (crop-intubation) methodology. The ingredients tesled were com, wheat bran (WB), two sources of soybean meal (SBM 1 and SBM 2), cottonseed meal (CSM), poultry by-product (PBP), and two samples of meat and bone meal (MBM 1 and MBM 2). A group ofthree roosters was fasted 24 hours prior lo each assay to allow measuremenl of endogenous amino acid production. True lysine digestibility (TLD) in CSM (71.8%) was signifzcantly lower (P<.01) than ia alt the other feed sources.:, No differences (P>.01) were found for ltD among the other ingredients. Means and standard error of means for TAADwere: coim 103.03±4.30. WB 90.35±2.26, SBM 1 93.13±1.55, SBM2 92.99±2.39, CSM 81.16±4.67, PBP 86.23±2.14, MBM 1 86.20±2.49, MBM 285.98±2.26. In general lhe averages of the coefticients for TÁAD of fite ingredients used are in fite range of lhe values reported in the literature and can be used to formulate diets based on amino acid digestibility. |
