Summary: The effect of carbohydrase on the digestibility of cereal diets in pigs was investigated. The study found that carbohydrase complex can enhance the digestibility of starch, non-starch polysaccharides, and nutrients in cereal grains. In particular, the complex can partially degrade high-molecular weight polysaccharides and increase their apparent ileal digestibility.

Summary: In vitro models of digestion are valuable tools for studying the behavior of dietary fiber sources in the gastrointestinal conditions. This study compared the characteristics and impact of cell wall integrity on protein bioaccessibility and digestibility in vivo and in vitro. Results showed that the form of dietary fiber intake has a significant effect on protein digestion, and intact cell walls of the fiber can modulate protein digestion. Comparison between in vivo and in vitro digestion analysis demonstrated a high similarity in terms of particle size measurements.

Summary: Two experiments were conducted to evaluate the effects of exogenous carbohydrases on nutrient and energy utilization of corn with different compositions. The results showed that the energy value, digestibility of dry matter and nitrogen of corn depended on the region where it was grown and the genetic characteristics of corn. Supplementation of exogenous carbohydrases could improve the utilization efficiency of energy and nutrients.

Summary: This experiment aimed to investigate the effects of adding an enzyme premix containing xylanase and glucanase to the diets of growing pigs. The results showed that the addition of enzymes improved the digestibility of energy and digestible energy in the diets, regardless of the grain source or the inclusion of co-products. However, the addition of enzymes had no effect on the digestibility of total dietary fiber. The inclusion of co-products decreased the average daily gain and gain to feed ratio in the pigs. Overall, the enzyme mixture used in this experiment has the potential to improve the digestibility of energy in pig diets.

Summary: This study evaluated the effects of adding different doses of fibrolytic enzymes (EFEs) and storage time on the fermentative profile and nutritive value of maize silage. The results showed that EFE treatment did not improve nutrient digestibility, but increased acetic acid concentration and decreased ethanol and ester concentrations. Prolonged storage resulted in higher dry matter losses and acetic acid content, but lower ethanol concentration. However, these differences may not be biologically relevant due to the relatively low concentrations of ethanol and esters in all treatments.

Summary: Histidine is an essential amino acid for protein synthesis in pigs and plays a vital role in their metabolic system. Growth performance and plasma histidine concentration may not effectively assess histidine requirement due to the contribution of histidine-containing proteins. Hemoglobin, carnosine, and trypsinogen are better indicators for determining histidine requirement.

Summary: Zinc glycinate could be used as an alternative to zinc oxide in nursery feeds to reduce the negative impacts of F18(+)E. coli(+) on growth and intestinal health of nursery pigs. The supplementation of zinc glycinate at 400 mg/kg could effectively replace the pharmaceutical use of zinc oxide with similar effects. This study shows that zinc glycinate can enhance intestinal health and improve growth performance of nursery pigs challenged with F18(+)E. coli.

Summary: Pigs, especially the Mashen and Large White breeds, exhibit diverse transcriptional responses in skeletal muscle under cold stress. The Mashen pigs demonstrate stable physiological homeostasis and a strong immune response, while the Large White pigs primarily regulate heat production and energy metabolism. The PRSS8 gene plays a role in cellular energy metabolism and thermogenesis. These findings provide valuable insights into the molecular mechanisms underlying cold adaptation in pigs.

Summary: Data from Europe shows that commercial pig diets in the United States contain more calcium than formulated, while the analyzed concentrations of total calcium and phosphorus in these diets are not higher than formulated values. The study found that on average, the calculated calcium content in US pig diets was 0.19 percentage units higher than the formulated values, while the oversupply of phosphorus was only 0.06 percentage units. Therefore, more attention should be given to the actual concentration of calcium in pig diets to avoid oversupply and its negative effects.

Summary: This study investigated the effects of soy protein concentrate (SPC) replacing animal protein supplements on mucosa-associated microbiota, intestinal health, and growth performance of nursery pigs. The results showed that SPC can replace fish meal, poultry meal, or blood plasma without affecting growth performance and intestinal health of nursery pigs. However, when SPC replaced all three animal protein supplements, it reduced the growth of nursery pigs mainly by reducing feed intake.

Summary: The optimal neutral detergent fiber levels for Mashen pigs and Duroc x Landrace x Yorkshire pigs were found to be 18% and 13.5%, respectively. Increasing the fiber level in the diet resulted in improved growth performance, intestinal development, and regulation of lipid and amino acid metabolism in pigs. Mashen pigs had a stronger ability to digest fiber due to the presence of fiber fermentation bacteria. This study provides insights into the roughage tolerance of different pig breeds and the potential benefits of dietary fiber in pig production.
