  Scientists Decoding Muscle Loss

  In a study published in SCIENCE CHINA Life Sciences on February 21, Prof. YIN Yulong from the Institute of Subtropical Agriculture, Chinese Academy of Sciences uncovered compelling evidence linking LPS-induced muscle mass loss to the reduction of Bacteroidetes abundance, increased inflammation, and disruption of mitochondrial morphology.

  Stronger Carbon Sequestration in Paddy Soils than Adjacent Upland Counterparts

  Increasing carbon sequestration in agricultural soils is beneficial to promote crop productivity and combat climate change. Paddy and upland lands are the general land-use types of agroecosystems. Researchers led by Prof. Chen Xiangbi from the Institute of Subtropical Agriculture of the Chinese Academy of Sciences (CAS) previously demonstrated that compared to their nearby upland soils, paddies were 39%–127% more effective in organic carbon sequestration, with greater differences in warmer than cooler climates.

  Lithology and Niche Habitat Effectively Control Arbuscular Mycorrhizal Fungi

  Karst landscapes are distributed worldwide, with the karst region in southwest China accounting for 5.8% of the national land area. The differing chemical properties of bedrock between karst carbonate rocks and non-karst clastic rocks are significant factors influencing the arbuscular mycorrhizal fungi (AMF) community by altering soil properties and plant diversity. The researcher group of Prof. Wang Kelin from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences (CAS) most recently found that lithology and niche habitat have significant effect on arbuscular mycorrhizal fungal abundance and their interspecific interactions

  Progress in Understanding Early Weaning-induced Small Intestinal Epithelial Atrophy from the Perspective of Intestinal Stem Cells

  The research team of Professor Yulong Yin from Institute of Subtropical Agriculture, Chinese Academy of Sciences, recently clarified the mechanism underlying early weaning-induced abnormality in the development of small intestinal epithelium from the perspective of ISCs. They found that early weaning depressed the self-renewal of ISCs and attenuated the activity of ISCs-driven intestinal epithelial regeneration and crypt expansion in vivo and ex-vivo.

  Effects and Mechanisms of Probiotics/Synbiotics on Regulating Intestinal Health and Meat Quality of Offspring Bama Pigs Through "Mother-Offspring Integration"

  Recently, a research team led by professor Xiangfeng Kong from the Institute of Subtropical Agriculture, Chinese Academy of Sciences, systematically studied the effects of dietary probiotics and synbiotics supplementation during gestation and lactation on Bama mini-pigs and explored the mechanism from the aspects of nutrient metabolism, intestinal microecology, and gene expression.

• What Can Reflect Shaziling Pigs’ Meat Quality Traits?

  Recently, a team of researchers from China Agricultural University and the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences conducted a study to evaluate the composition of amino acids, fatty acids, and metabolic profiles in the longissimus thoracis (LM) muscle sample from Shaziling pigs aged 30, 90, 150, 210, and 300 days, with the aim of investigating the effects of age on the abovementioned parameters and of identifying what can reflect Shaziling pigs’ meat quality traits.

  Replacing ZnSO4 with Zn-Glycine In the Diets of Ewe Promotes the Pancreatic Function of the Offspring

  Researchers from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences investigated the effects of replacing inorganic Zn (ZnSO4) with organic Zn (Zn-Glycine) in the diets of ewe on the pancreatic function of the offspring. They found that pancreatic zinc contents in kids tended to be increased when replacing ZnSO4 with Zn- Glycine. The serum insulin concentrations were greater and the glucagon were less in the Zn- Glycine group when compared to ZnSO4 group. The activities of lipase and chymotrypsin were enhanced when replacing ZnSO4 with Zn-Glycine.

  Dietary Betaine offers New Insight for Local Bama Mini-pigs Breeding

  Recently, Xiangfeng Kong 's research team from the Institute of Subtropical Agriculture, Chinese Academy of Sciences, systematically studied the feeding effects of dietary betaine in sows and piglets diet on Bama mini-pigs and discussed its mechanism of hormone secretion, nutrient metabolism, intestinal microecology, gene expression, and other aspects. This team found that dietary betaine supplementation can improve the composition of colostrum and intestinal microecology of sows, and regulate the body's nutritional metabolism and reproductive hormone secretion, thereby improving the reproductive performance of sows. Dietary betaine can also enhance the body's immune function and antioxidant properties, improve intestinal microecology, and regulate the secretion of hormones and nutrient metabolism, thereby promoting the growth and development of suckling piglets.
