Chongqing Three Gorges Vocational College via XuetangX

Overview

"Excellent course: Chongqing Municipal Excellent Course; 

On-campus teaching time: the first and second semesters of the 2021-2022 academic year and the first and second semesters of the 2022-2023 academic year; 

Student type: freshmen and sophomores majoring in Animal Husbandry and Veterinary 

Number of students: 2,775 

Learning effect: good 

Analysis of advantages and disadvantages of the course: In this course, starting from the feed production workflow, the characteristics of the digestive tract of aquatic animals, the functions of nutrient components of feeds for terrestrial and aquatic animals, the use of feed additives, and the nutritional functions of feed raw materials are used to learn advanced scientific cases, so as to design feed formulas, summarize research methods of green feeds, and sort out research plans for replacing antibiotics. 

The teaching mode of double guidance by two tutors on campus and off campus is applied, emphasizing the three-combination teaching design of education and society, teaching and production, and learning and practice. The teaching mode of "" self-learning of online resources + offline multi-dimensional classroom + trinity practice + multiple assessment systems"" is established to achieve the new agricultural science goal of ""consolidating the foundation, expanding knowledge, and cultivating ability"". 

Disadvantages: The course is the core course of the Aquaculture Technology Major, and the scope of application is relatively limited."
