• Bacterial Laccase-like Genes and Fungal Laccase Gene are Present in Subtropical Arable Lands

  A team of researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) sampled from typical six sites containing the main soil types and agricultural land uses in subtropical China, and then detected the laccase activity and the abundance, diversity and composition of bacterial laccase-like genes and fungal laccase genes.

• A Non-toxic New Iron Supplement Candidate: Ferrous N-carbamylglycinate Chelate

  In order to improve the iron defiiency problems in new born piglets, the researcher group in Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) had designed a new iron chelate ferrous N-carbamylglycinate as an iron fortifier (patent No: 201310142525.4), which aimed to improve iron bioavailability and reduce extra digestion.

• How Ruminal Protein and Feed Intake Effect on Endogenous Nitrogen and Amino Acids Flow in Goats?

  Rumen is one of the most important parts for the ruminants, which help ruminant acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. In order to make a more accurate estimation of true N digestibility and know how much dietary N is needed to cover the requirement for EN and endogenous AA (ENAA) loss by the knowledge of EN loss, PhD. ZHOU Chuanshe and his group from Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) ,led by professor TAN Zhiliang, carried out an experiment.

• MicroRNA-27b Overexpression Improves Mitochondrial Function and Insulin Resistance

  Mitochondria are the principal energy sources of the cell that convert nutrients into energy through cellular respiration. Recently, researchers in the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) and Clinical Laboratory Department, Hunan Guangxiu Hospital studied the effects of MicroRNA-27b (MiR-27b)-a target of resveratrol, on mitochondrial function in skeletal muscle and C2C12 cell myoblast.

• How Genotype and Dietary Protein Intake Co-regulate Expression of Amino Acid/Peptide Transporters in Porcine Skeletal Muscle?

  A balanced supply of dietary proteins and amino acids (AAs) is necessary for the optimal growth, development, and reproduction of animals.As pig strains may vary in their capacity to recognize changes in AA concentration in body fluids, the utilization of free AAs may also differ among pig strains. According to Ph.D candidate LIU Yingying from Institute of Subtropical Agriculture, Chinese Academy of Science(ISA), differences among different strains of pigs in their muscle growth, meat quality, and intermuscular adipose deposition, may lead to dietary protein-dependent differences in AA metabolism.

• Where does All the Water Go in Subtropical Fengcong Karst Areas of Southwest China?

  when rainfall falls on the karst system, where does water go? What flow path does the water take? What is the percentage of water can be used by humans? And will the climate extreme cause more severe water shortage in the karst area of southwest China?Using plot-scale rainfall simulations on a trench excavated to the epikarst lower boundary (with a depth of about 4 m), a team of researchers from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA), investigated the rainfall partitioning pattern of a soil-mantled, humid subtropical soil-epikarst system characterized by shallow soils overlaying a highly irregular epikarst surface.

• Pig genotype, diet, and physiological stage interact on signaling pathways related to protein synthesis

  Prof. YIN Yulong's group from the Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA) speculated that the difference between these two genotypes of pigs in their muscle growth, meat quality, and intermuscular adipose deposition may lead to dietary protein-dependent differences in protein deposition and related signaling pathways in different types of skeletal muscles.

• Early-weaning Effects Expression of Proteins Involved in Energy Production

  a study cooperated by Dr. XIONG Xia and Dr. YANG Huangsheng from Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA)has found that early-weaning differentially affect the expression of proteins involved in energy production of enterocytes along the jejunal crypt-villus axis.

• Hydrogen in Headspace and Bicarbonate in Media Has Effects on Methane Production and Rumen Fermentation

  PhD Qiao Junyi in Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA)used NaH13CO3 and H2 as materials to investigate the 13CH4 production efficiency(PE) produced by the reduction of NaH13CO3, and they used lucerne hays as substrates to evaluate the effects of NaH13CO3and H2 additions on ruminal fermentation, CH4 production and methanogen populations used in the vitro gas production techniques.His study indicates that both CO2 and H2 concentrations can influence the methanogenesis in the rumen, and a small part of the CO2 utilized for methanogenesis is from bicarbonate(such as NaHCO3) in media. The headspace hydrogen and media bicarbonate had significant effects on CH4 production and rumen fermentation.

• When Exchange Diet, What Happened to Western and Indigenous Chinese Pig Breeds?

  Although muscle growth and meat quality considerably differ between Western and indigenous Chinese pig breeds, it is not clear how nutrients mediate the effect of genetic background on animal growth and meat quality.Ph.D candidate LIU Yingying from Institute of Subtropical Agriculture, Chinese Academy of Sciences (ISA), the livestock industry faces the challenge of increasing the intramuscular fat (IMF) content of pork so that consumers may have a satisfactory experience, while simultaneously producing minimal visible fat, which is a deterrent to health-conscious consumers.
