        Effect of a microbial phytase on growth performance, plasma parameters and apparent ileal amino acid digestibility in Youxian Sheldrake fed a low-phosphorus corn-soybean diet

        He, Shaoping,Medrano, R.F.,Yu, Qifang,Cai, Yixin,Dai, Qiuzhong,He, Jianhua Asian Australasian Association of Animal Productio 2017 Animal Bioscience Vol.30 No.10

        Objective: This study investigated the effect of microbial phytase supplementation on growth performance, tibia ash, plasma parameters, apparent ileal digestibility (AID) of amino acid (AA) and apparent digestibility of nutrients in Youxian Sheldrakes fed with low-phosphorus (P) cornsoybean diets. Methods: A total of 350 Youxian Sheldrakes (7d old) were randomly divided into 5 treatment groups: positive control (PC) group has adequate available P diet (0.42% and 0.38%, starter and grower), negative control (NC) group were deficient in available P (0.32% and 0.28%, starter and grower) and NC diet was supplemented with 3 levels of microbial phytase (500, 750, and 1,000 U/kg). Results: Dietary supplementation of phytase in NC diet improved the average daily gain, increased the levels of serum calcium (Ca), tibia Ca and P, AID of AA and apparent digestibility of energy and Ca in starter stage (p<0.05). There was an increased (p<0.001) in the utilization of P from 17.3% to 23.9%. Phytase supplementation (1,000 U/kg) has shown that the AID of His, Thr, Val, indispensable AA, Glu, Pro, and dispensable AA was higher (p<0.05) than that of NC. Moreover, phytase supplementation improved (p<0.05) serum and tibia Ca and P, AID of AA and apparent digestibility of dry matter, crude protein, energy, P and Ca, and reduced (p<0.05) feed to gain ratio (F/G) and the levels of serum alkaline phosphatase in grower stage. Likewise, an increase (p<0.001) in the utilization of P was noticed from 12.6% to 17.2%. Supplement phytase at 750 U/kg improved the AID of His, Thr, Asp, Cys, Pro, and Ser (p<0.05). Conclusion: The microbial phytase supplement could improve growth performance, AID of some AA and apparent utilization of other nutrients in Youxian Sheldrakes, and reduce excreta P load to environment.

      • Design of Hospital EMR Management System

        Hongfeng He,Yixin Yan 보안공학연구지원센터 2014 International Journal of u- and e- Service, Scienc Vol.7 No.5

        In order to eliminate the drawbacks of EMR system management, this paper proposes an EMR system management model based on SNMP. The data of network management, which is stored in the Web page or Web server database, is collected by SNMP from MIB library. The information resources of the system, can not only be monitored by the management station through reading the values of the information database, but can be controlled by modifying certain values. The network and system can be managed, monitored, maintained and reported by using the Internet technologies of Web server, browser, and so on, so that the main control room of the hospital can communicate with other departments in computers and finally to achieve overall monitoring and integrated management. It can not only protect the EMR system to operate secure and stable, but also can reduce the cost of network management.

      • The Cultivation and Improvement of Digital Literacy Skills of College Students: Based on the Perspective of Talent Needs of Enterprises

        Ding Weijie,He Qingqing,Wang Yixin 한중경제문화학회 2024 한중경제문화연구 Vol.25 No.-

        With the wave of digital economy sweeping the world, artificial intelligence, blockchain, cloud computing, 5G, ChatGPT and other information technologies are developing rapidly. All walks of life are undergoing changes, and people’s thinking, cognition, life, study, and work are changing accordingly. Both developed and developing countries are also facing new situations and challenges in politics, economy, science and technology, culture, and education. It can be said that digitalization itself and its impacts are related to the development of the future world and affect every citizen of the earth. Digital literacy and skills derived from digitalization have gradually become the focus of attention from all walks of life. In terms of college students’ digital literacy and digital literacy skills, it mainly refers to the digital ability that college students should have and use in study, employment, and future work under the background of informatization and digitalization. Although digital literacy and digital literacy skills have been paid more and more attention by the international community and schools, there is no unified definition of digital literacy and digital literacy skills by various countries and international organizations, and there are some differences in the use of this concept by countries and regions. From the perspective of enterprises’ demand for digital talents, this paper puts forward some suggestions on the training and improvement of college students’ digital literacy skills.

        Microbial diversity in the rumen, reticulum, omasum, and abomasum of yak on a rapid fattening regime in an agro-pastoral transition zone

        Dan Xue,Huai Chen,Xiaolin Luo,Jiuqiang Guan,Yixin He,Xinquan Zhao 한국미생물학회 2018 The journal of microbiology Vol.56 No.10

        The ruminant digestive system harbors a complex gut microbiome, which is poorly understood in the case of the four stomach compartments of yak. High-throughput sequencing and quantitative PCR were used to analyse microbial communities in the rumen, reticulum, omasum, and abomasum of six domesticated yak. The diversity of prokaryotes was higher in reticulum and omasum than in rumen and abomasum. Bacteroidetes predominated in the four stomach compartments, with abundance gradually decreasing in the trend rumen > reticulum > omasum > abomasum. Microorganism composition was different among the four compartments, all of which contained high levels of bacteria, methanogens, protozoa and anaerobic fungi. Some prokaryotic genera were associated with volatile fatty acids and pH. This study provides the first insights into the microorganism composition of four stomach compartments in yak, and may provide a foundation for future studies in this area.
