Special Issue Information

Dear Colleagues,

The porcine industry has made significant contributions to global food security, international trade, and agricultural economies in the modern era. For many years, quantitative studies on nutrient digestion and utilization have been conducted on growing pigs. Pigs require a variety of essential nutrients to satisfy their needs for maintenance, growth, reproduction, lactation, and other processes. Numerous elements, such as genetic variation, the environment, the availability of nutrients in feedstuffs, the presence of disease, and other stressors, may have an impact on pigs' optimal performance and reproduction. It is essential, both economically and environmentally, to correlate the nutrient supply to the nutrient requirements for pig production. As animal agriculture evolves, it has become increasingly vital to continually update the nutritional needs of hogs through research on swine nutrition and energy metabolism. Researchers are urged to examine the effect of dietary components on the energy metabolism of pigs, including the utilization of various energy sources, amino acids, and vitamins. In addition, research evaluating the effects of novel feed constituents, additives, and supplements on energy utilization and nutrient absorption in pigs is strongly encouraged.

In this Special Issue, all swine researchers are encouraged to submit their valuable research findings on swine nutrition and metabolism. This Special Issue seeks to provide a forum for you and other researchers to present your valuable research findings in this field. In addition, new insights will be gained from the most recent developments in porcine nutrition and energy metabolism.

We invite submissions in a variety of formats, including original research articles, reviews, mini-reviews, perspective articles, short communications, etc., including but not limited to the following:

  • Swine nutrition
  • Energy metabolism in swine
  • Pathogenicity and virulence
  • Swine gut microbiome
  • Natural antimicrobials in swine nutrition
  • Swine health and management
  • One-health approach in swine
  • Dietary supplements in swine
  • Alternative to antibiotics in the pork industry

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs).

This study aimed to investigate the dynamic changes in hepatic glucose metabolism in response to early weaning. A total of 60 piglets were randomly selected and weaned at 21 days old. Six piglets were slaughtered on the weaning day (d0) and at 1 (d1), 4 (d4), 7 (d7), and 14 (d14) days postweaning. The results illustrated that body weight significantly increased from d4 to d14 (p < 0.001). Serum glucose fell sharply after weaning and then remained at a low level from d1 to d14 (p < 0.001). Serum insulin decreased from d4 (p < 0.001), which caused hepatic glycogen to be broken down (p = 0.007). The glucose-6-phosphatase activity increased from d0 to d4 and then decreased from d4 to d14 (p = 0.039). The pyruvate carboxylase activity presented a significant sustained increase from d0 to d14 (p < 0.001). The succinate (p = 0.006) and oxaloacetate (p = 0.003) content on d4 was lower than that on d0. The succinate dehydrogenase activity (p = 0.008) and ATP (p = 0.016) production decreased significantly on d4 compared to that on d0. Taken together, these findings reveal the dynamic changes of metabolites and enzymes related to hepatic glycometabolism and the TCA (tricarboxylic acid) cycle in piglets after weaning. Our findings enrich weaning stress theory and might provide a reference for dietary intervention. Full article

This review aimed to clarify the mechanisms through which exogenous enzymes (carbohydrases and phytase) influence intestinal health, as well as their effects on the nutrients and energy matrix in diets fed to poultry and pigs reared under sanitary challenging conditions. Enzyme supplementation can positively affect intestinal microbiota, immune system, and enhance antioxidant status. Although enzymes have been shown to save energy and nutrients, their responses under sanitary challenging conditions are poorly documented. Immune system activation alters nutrient partitioning, which can affect the matrix values for exogenous enzymes on commercial farms. Notably, the carbohydrases and phytase supplementation under sanitary challenging conditions align with energy and nutritional valorization matrices. Studies conducted under commercial conditions have shown that matrices containing carbohydrases and phytase can maintain growth performance and health in poultry and pigs. However, these studies have predominantly focused on assessing a single level of reduction in energy and/or available phosphorus and total calcium, limiting our ability to quantify potential energy and nutrient savings in the diet. Future research should delve deeper into determining the extent of energy and nutrient savings and understanding the effects of alone or blended enzymes supplementation to achieve more specific insights.
