Summary: This study investigated the effect of a novel consensus bacterial 6-phytase variant on the apparent ileal digestibility of amino acids in broilers. Using data from multiple trials and locations, a model was developed to accurately predict the impact of the phytase on the digestible amino acid content in the diet. The results demonstrated consistent improvements in the digestibility of amino acids by the phytase, highlighting its potential in commercial feed formulations.

Summary: A multistate experiment was conducted to investigate the differences in the standardized ileal digestibility (SID) of amino acids (AA) among different sources of bakery meal. The results showed that there were significant differences in SID of all AA except Pro among the 11 sources of bakery meal, indicating higher variability among sources of bakery meal compared to other ingredients.

Summary: The standardized ileal digestibility (SID) of soybean meal (SBM) did not differ significantly when fed to non-pregnant and late-gestating sows, but varied among different samples when fed to mid-gestating sows. The SID values for certain amino acids were influenced by sow gestation stages, with differences observed between mid-gestating, late-gestating, and non-pregnant sows in terms of amino acid digestibility.

Summary: This study investigated the effects of exogenous protease supplementation on the digestibility and performance of broilers fed soybean meals processed at different levels. The results showed that protease supplementation improved digestibility and performance at mild processing levels but had no significant effect at harsh processing conditions.

Summary: This study compared the digestibility of amino acids in faba beans and field peas between chickens and pigs. Different cultivars of field peas had varying digestibility of amino acids. The experiment showed that broiler chickens had higher digestibility of amino acids in faba beans and three cultivars of field peas. The digestibility of lysine in 4010 field peas was lower for both chickens (85.1%) and pigs (78.9%).

Summary: This study aimed to estimate the dietary requirement of standardized ileal digestible lysine for male broiler chickens aged 21-28 days. The results showed that as the lysine concentration in the diet increased, there was a linear and quadratic increase in weight gain, feed intake, and feed conversion ratio. The lysine intake also linearly increased with the lysine concentration. The dietary lysine requirement for optimal body weight gain and feed conversion ratio for 21-28 days old male broilers was estimated to be 10.7 g/kg and 10.9 g/kg, respectively.

Summary: This study determined that the SID Met + Cys requirement for 15-30 kg barrows is 6.61 g/kg for optimal daily weight gain, without the need to maintain the 1:1 ratio between sulphur amino acids (SAA). Increasing the SID Met + Cys levels led to increased daily intake of these amino acids, affecting blood parameters such as plasma glucose and total cholesterol.

Summary: Two experiments were conducted to determine the DE, ME, and SIDC of amino acids in barley for pigs and develop prediction equations based on its chemical composition. The results showed that barley had variations in its chemical composition, which influenced its DE, ME, and SIDC. Fiber fraction was found to be a key predictor for the energy and amino acid digestibility.

Summary: The objective of this experiment was to determine the standardized ileal digestible lysine requirements for pregnant sows individually housed under commercial farm conditions. The study found that the SID Lys requirement for maximal total born piglets alive per litter in the mid-gestation period is 11.1 g/d (1.36 g/Mcal metabolizable energy; 0.44%), and in the late gestation period is 16.1 g/d (1.79 g/Mcal metabolizable energy; 0.58%).

Summary: This study evaluated the digestibility of protein and amino acids from different protein sources and the intestinal morphology in pigs during the first four weeks after weaning. The results showed that the time after weaning was more important for protein digestibility than the source of protein. The lower number of mature epithelial cells and smaller absorptive area in the small intestine during the early postweaning period may explain the poor protein digestibility.

Summary: This study explores nutritional strategies to counteract bone demineralization in ovarierectomized rats. Calcium supplementation improves bone mineral density and strength, while inulin and lactose show beneficial effects on bone mineralization. The study also reveals the modulation effect of calcium on gut microbiome composition and function.

Summary: This study suggests that the maximum dietary zinc concentration regulated by the EU may increase the risk of zinc deficiency and related health issues in piglets after weaning. High dietary zinc levels have both antimicrobial effects and an increased risk of antimicrobial resistance. The findings also indicate that the actual zinc requirement for newly weaned piglets may be higher than previously assumed.

Summary: This study aimed to evaluate the effect of additional dietary tryptophan (Trp) and threonine (Thr) on the performance, probability of diarrhea, intestinal permeability, and morphology in weaned pigs. The study found that supplementation with Trp and Thr together stimulated neutral mucin production in the large intestine and reduced the number of days where antibiotics treatments against diarrhea is necessary.

Summary: Excessive dietary Zn in pigs leads to increased risk of antibiotic resistance gene development in soil bacteria and has a negative impact on soil fertility when pig slurry is spread to fields. A meta-regression analysis was conducted using data from 10 published studies to develop a model for the relationship between daily Zn intake and daily Zn excretion in weaned pigs. The results showed that Zn excretion increased linearly with Zn intake, and the formulation of added Zn had no influence on Zn excretion.

Summary: The combination of milk and rice protein did not significantly affect the growth of weaned pigs, while a diet consisting purely of plant-based proteins led to reduced growth, likely due to lower feed intake and lower-than-expected amino acid digestibility of rapeseed protein. Milk protein did not seem to specifically stimulate growth factors or biomarkers of growth via insulin and IGF-1 signaling pathways beyond the favorable amino acid composition and digestibility it provided.
