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.
Recently, a research team from Institute of Subtropical Agriculture, Chinese Academy of Sciences and Hunan Agricultural University revealed that intestinal MyD88 deficiency ameliorated intestinal oxidative injury. The main findings of this study include: 1) Intestinal MyD88 deficiency ameliorated intestinal mitochondrial dysfunction and DNA damage during PQ exposure; 2) There was a marked decrease in ROS in MyD88-deficient cells during PQ exposure, which were consistent with high activity of antioxidative enzymes; 3) Intestinal MyD88 deficiency effectively ameliorated weight loss caused by intestinal oxidative injury in an autophagy-dependent manner.
Researchers from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences investigated the hypothesis that unrecorded period of feed intake was not the major factor to influence accuracy of recording daily feed intake in monitoring system, when response time after trigger of cow was increased.
Researchers from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences investigated the hypothesis that increasing starch intake can inhibit fiber digestibility through decreasing ruminal pH, increasing dissolved H2 (dH2) concentration and altering microbiota in the rumen.
Researchers from China Agricultural University and the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences investigated the relationship between dissolved hydrogen and fiber digestion in beef cattle fed with two types of forages (napier grass and corn stover) with different fiber structure.
Researchers from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences investigated the effects of sucrose supplementation alone on ensiling characteristics and bacterial community compositions of alfalfa silage. It was found that the ensiling time significantly decreased the crude fiber content, and increased the ammonia nitrogen, acetic acid content, and the relative abundance of Enterococcus in the silages. Supplementing alfalfa silage samples with different doses of sucrose decreased their pH levels and NDF, propionic acid, and butyric acid content. There was an increment in the RFV levels with the increments of the sucrose supplementations. Furthermore, the reduced levels of butyric acid suppressed harmful bacteria and the relative abundance of Lactobacillus and Enterococcus in the silage increased. All results suggested that sucrose supplementation could improve increasing its beneficial bacterial content and the feeding quality of alfalfa silage.
On August 26, the 6th International Conference on Food, Agriculture and Biotechnology (ICoFAB) was held at Mahasarakham University, Thailand. Over 150 scientists from China, Thailand, attended the conference. With invitation as the keynote speaker from the committee of the conference, professor WU Xin from the Institute of Subtropical Agriculture, Chinese Academy of Sciences att...
