Effects of heating soybeans on postruminal amino acid bioavailability, performance, and ruminal fermentation in lactating cows J. Anim. Sci. (IF 3.3) Pub Date : 2024-03-21 E A Petzel, S Acharya, E C Titgemeyer, E A Bailey, D W Brake
Soybeans can provide ruminally degradable protein, lipid and metabolizable amino acid (AA) to lactating dairy cows; however, soy-based trypsin inhibitors can limit protein digestion in nonruminants. Eight ruminally cannulated lactating Holstein cows were used to evaluate the impacts of soy-based trypsin inhibitors on nutrient disappearance, lactation, and plasma AA bioavailability. Treatments were

Effects of dietary protein level on intestinal function and inflammation in nursery pigs J. Anim. Sci. (IF 3.3) Pub Date : 2024-03-20 Sarah C Pearce, Mitchell J Nisley, Brian J Kerr, Chris Sparks, Nicholas K Gabler
High crude protein (CP; 21-26%) diets fed during the first 21 to 28 d post-weaning are viewed negatively because of a perceived increase in the incidence rates of diarrhea due to increased intestinal protein fermentation and/or augmented enteric pathogen burden. This is thought to antagonize nursery pig health and growth performance. Therefore, our objective was to evaluate the impact of low vs. high
