• Rumen-protected Glucose may Beneficial for Uterine Involution of Early Postpartum Dairy Cows

  Recently, researchers from the Institute of Subtropical Agriculture(ISA), Chinese Academy of Sciences, and Hunan Agricultural University fed the dairy cows with 0 or 200 g rumen-protected glucose twice every day from -7 ± 2 to 14 d to illustrated the effect of RPG on the uterine involution during the early post-natal period.

• How Do Herbivorous Geese Respond to Food Resource Changes Caused by Varied Water Regime?

  Researchers in the Institute of Subtropical Agriculture (ISA), Chinese Academy of Sciences combined remote sensing, field survey, laboratory testing, and control experiment to measure the variations in both food quantity and quality as cues explaining the responses of the two herbivorous goose species (Lesser white-fronted goose Anser erythropus and Bean goose Anser fabalis) in terms of habitat selection and diet composition in two successive wintering periods, 2016/2017 and 2017/2018.

  Chemical Fertilization Affects N and P Runoff Losses from Paddy Fields

  By designing the interaction treatments with different chemical fertilizers (0%, 50%, 70%, 100% and 150% of conventional dosage) and pesticides (0%, 50%, 70% and 100% of conventional dosage), researchers from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences (CAS) observed ponding water N and P concentrations and N and P runoff losses with high-frequency in three rice seasons in the double rice-cropping paddy fields in hilly areas in South China.

  Effects of Organic Inputs on Microbial Carbon Use Efficiency and Necromass Accumulation in Paddy Soils Revealed

  The researchers from the Instituted of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences examined the microbial CUE, microbial biomass turnover, and necromass accumulation in rice rhizosphere and bulk soils subjected to long-term (31 years) fertilizations. Five fertilization treatments were included: no fertilizers, mineral fertilizers alone, mineral fertilizers plus rice straw incorporation, and mineral fertilizer combined with a low or a high amount of organic manure.

  Forest Management in Southern China Generates Short Term Extensive Carbon Sequestration

  Recently, researchers from the Institute of Subtropical Agriculture (ISA) of Chinese Academy of Sciences, University of Copenhagen (Denmark), CREAF (Spain), INRA, Institute Pierre Simon Laplace (both France), the University of Oklahoma, the Institute of Remote Sensing and Digital Earth (China) and other universities identified different forest and land management strategies as well as their biomass carbon sinks from 2002 to 2017 in southern China by combing optical and low frequency passive microwaves satellite data. They also evaluated soil moisture trends from 2010 to 2017 for this area.

• HMB is Required for Leucine to Inhibit Muscle Protein Degradation

  Using a starvation model, a team of researchers from China Agricultural University and the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences found that HMB (50 μM) is more superior than leucine (0.5 mM) in effectively suppressing protein degradation of C2C12 myotubes. However, it remains unknown whether HMB mediates the inhibitory effects of leucine on protein degradation, and whether the protective effect of HMB is still more effective than that of leucine when its treatment concentration is fay beyond physiological limits.
