Summary: This study evaluated the protein quality traits of a pea population and identified several QTLs associated with protein concentration and digestibility. The results showed co-localization of certain QTLs with known QTLs for seed protein concentration. These findings are important for improving the nutritional quality of peas and enhancing their competitiveness in the plant-based protein market.

Summary: The study reveals that both protein and starch levels have an impact on the total-tract digestibility and feed efficiency of calves. High protein and high starch diets contribute to improved digestion and feed utilization in calves.

Summary: Nutrient synchronisation of protein and carbohydrates is a promising practice to improve ruminal nutrient utilisation. The effects of adding non-fibre carbohydrates with different rumen degradation rates in high-forage diets on ruminal fermentation, efficiency, and microbial flow were investigated using the Rumen Simulation Technique.

Summary: This study investigated the effect of lignocellulose-degrading bacteria-inoculated whole-plant corn silage on the growth performance, rumen fermentation, and rumen microbiome in sheep. The results showed that inoculated corn silage improved the growth performance and fiber digestibility of sheep, and altered the structure and function of the rumen microbiome. These findings provide novel insights into the microbial mechanisms underlying improvement in the growth performance of sheep.

Summary: The study demonstrated that feeding ensiled rice straw with novel Crabtree negative yeast strains significantly improved the digestibility of rice straw, rumen fermentation, and milk protein content in dairy cows. C. tropicalis KKU20 strain resulted in the highest digestibility of rice straw in tropical crossbred lactating Holstein cows.

Summary: This study aimed to evaluate the effects of dietary crude protein and rumen-protected lysine supplementation on lactation performance, amino acid balance, nitrogen utilization and hindgut microbiota in dairy cows. The results showed that rumen-protected lysine supplementation increased dry matter intake, milk protein yield, and energy corrected milk. It also had an impact on the composition of amino acids, nitrogen utilization, and the bacterial community in the hindgut.

Summary: This study assessed the supplementation of methionine and lysine on the lactational performance of fall-calving grazing dairy cows. The results showed that supplementation of these amino acids improved milk production.

Summary: This study analyzed the total lysine and reactive lysine in six cooked or processed foods using a guanidination-based bioassay. The results showed that the true ileal digestible reactive lysine was significantly lower than the true ileal digestible total lysine for cooked black beans, toasted wheat bread, and processed wheat bran by 89%, 55%, and 85% respectively. Therefore, the study demonstrates the importance of determining the true ileal digestible reactive lysine contents of processed foods.

Summary: This study investigated the effects of taurine supplementation on rumen fermentation, bacterial community, metabolomics, nitrogen metabolism, and plasma biochemical parameters in beef steers. The results showed that taurine supplementation increased the concentration of taurine and microbial crude protein in the rumen, improved fiber digestibility, and modified the rumen bacterial community. It is necessary to further clarify the hydrolysis of taurine in the rumen of steers.

Summary: This study evaluated the effects of ensiling length, storage temperature, and their interaction with crude protein levels on rumen fermentation and post-ruminal nutrient digestibility of sorghum-soybean forage mixtures. The results showed that ensiling beyond 75 days significantly reduced crude protein digestibility.

Summary: The study compared the effects of two diets on amino acid requirements in growing rabbits, finding that high growth rate animals did not show significantly higher performance when fed a high amino acid diet compared to a medium amino acid diet. Animals preferred the medium diet, indicating potential for precision protein nutrition in growing rabbits.

Summary: The study aimed to evaluate the impact of replacing soybean meal crude protein with red clover silage in total mixed rations on ruminal degradation and intestinal digestibility of essential amino acids. The results showed that increasing levels of red clover silage in the diet led to higher ruminal degradation of EAA but reduced their intestinal digestibility, ultimately affecting the absorbable EAA in the intestine.

Summary: The study aimed to investigate the impact of different dietary protein sources and rumen nitrogen balance on lactating dairy cows. The results suggest that different dietary ingredients may lead to varying animal responses under negative rumen nitrogen balance.

Summary: This study investigated the effects of supplementing rumen-protected methionine (RPM) or lysine (RPL) alone or in combination on milk yield, milk components, rumen fermentation, and microbiome in lactating yaks. Results showed that the supplementation of RPM and RPL can alter rumen microbial populations, which in turn affect rumen fermentation and metabolites available for milk synthesis in lactating yaks.
