Amino acids and energy digestibility in extruded or roasted full fat soybean fed to broiler chickens without or with multienzyme supplement containing protease, phytase, and fiber degrading enzymes

Research Note: Impact of Eimeria on apparent retention of components and metabolizable energy in broiler chickens fed single or mixture of feed ingredients-based diets

“…The AR of components and AMEn were calculated according to Adeola et al (2016) . The AME contents for the test ingredients were calculated using measured AME value of the test diets ( AMEtd ) and the proportions of other (cornstarch, sucrose, and soy oil) energy yielding ingredients ( poeyi ) and the proportions of the test ingredients ( poti ) as previously described in Thanabalan et al. (2021) using the following equation: where AMEti is AME of the test ingredient (corn, wheat, SBM, or PM) and AMEnfd is AME of the NFD diet.…”

Influence of extruded soybean meal with varying fat and oleic acid content on nitrogen-corrected apparent metabolizable energy in broilers

“…However, soybean products also contribute 20 to 30% of ME in poultry diets. The ME values of SBMs vary according to processing techniques ( Pacheco et al, 2013 ; Rueda-Agudelo and Giraldo-Mejía, 2018 ; Mateos et al, 2019 ; Thanabalan et al, 2021 ; Abdollahi et al, 2022 ), varieties or genotypes ( Parsons et al, 2000 ; Valencia et al, 2009 ; Loeffler et al, 2013 ), and geographical origins ( de Coca-Sinova et al, 2008 ; Silva et al, 2022 ). Recently, soybean cultivars with varying high oleic ( HO ) fatty acid profiles (high oleic, low linolenic acid) have been developed to enhance the shelf-life and unsaturated fatty acid profile of soybeans and enrich meat products with oleic acid ( Slaughter et al, 2019 ; Knowlton, 2022 ).…”
