Renovation Plan of Modern Livestock Housing

Dong Hai Feng Agricultural Circulation Park(DHF Park)

          TSC responds to the government’s 5+2 industrial innovation plan and has introduced ecological balance, environmental protection, and green concepts into pig farming industry and planned the first modernized green pig farm, the Dong Hai Feng Agricultural Circulation Park, where the business model of “secondary raw material recycling/by-products” is carried out, and was completed in 2020 and the official operation started in 2021. After the verification by British Standards Institution (BSI), the model complies with the BS 8001:2017: Framework for implementing the six principles of the circular economy, making it the very first livestock farmer in Taiwan and even in the world to obtain a standard verification statement, and the overall cycle maturity reaches the highest level- the optimization of the business model.

          The design idea of DHF Park is to not only solve the long-standing odor problem in the pig farming industry, but also realize the goal of an animal husbandry industry with automation, zero pollution, zero waste, zero emission, and being eco-friendly. Through the closed system of the negative water curtain, the overall temperature, humidity, and the risk of diseases and insects and pests are controlled, and the odor is all pumped into the deodorization system for treatment before being discharged. On the other hand, the strip flooring of the new pig house is equipped with a manure scraping system at the bottom that will send the pig manure and urine collected to the digestion tank through a closed pipeline, followed by separation process by a solid-liquid separator. The separated pig manure is dried or fermented before reuse. Part of the liquid is provided for biogas power generation through anaerobic fermentation, and the biogas slurry is used as the fertilizer in the farmland.

          DHF Park has established a regional biogas center and sewage treatment facilities, which not only can help with treatment of pig manure and urine inside and outside the farm,but also can disposewastewater and agricultural waste in the neighborhood. It is planned to treat 200 tonnes of pig manure and urine inside and outside the farm as well as external agricultural waste, and 200 CMD of domestic sewage and treated biogas slurry in the biogas center.

          By establishing the Dong Hai Feng Agricultural Circulation Park, TSC has established the best example of a circular economy model in the pig farming industry. In 2022, we received a total of 947 visitors from government units, schools, research institutions, and corporate groups for visits and exchanges. Moreover, this circulation park also obtained the Environmental Education Certification, making it the first environmental education site with the background of green energy pig farming in Taiwan. Students are guided to understand the pig farming industry from the pig breeds, the physiological structure, habits, animal welfare feeding methods to the back-end processing and whole pig utilization. The reduction of odor, the treatment and utilization of the manure and urine produced are also introduced. In the future, it is planned to be open to the neighboring communities as a place for recreation to continue our efforts to avoid being NIMBY facilities.

Investment project for the renovation of agricultural circulation pig farms

          To further apply the successful experience in Dong Hai Feng Agricultural Circulation Park to the other 13 pig farms, TSC further launched the Agricultural Circulation Pig Farm Renovation and Investment Project in 2018, which is TSC’s largest-scale investment project since the establishment of the livestock business in 1952. The purpose is to allow all sectors to redefine the pig farming industry and to lead the development, improvement, and upgrading of the domestic pig farming industry, reversing the stereotype of pig farms as NIMBY facilities.

          TSC is still the largest single pig farmer in Taiwan, and as a pig farming company, TSC is already the leader in domestic animal husbandry industry. However, the pig farm renovation project involves in many professional fields, including livestock housing, civil engineering, construction, electromechanical, information, environmental engineering, wastewater treatment, etc. In addition, the modernization of the animal husbandry industry is still in the transformation and development stage. There are very few professional teams that can be in charge of entire husbandry engineering design and also the integrated construction. Therefore, the user (TSC) is in charge of the design, and when the design is completed, the engineering construction is then put out to contract.

          This project involves as many as 13 pig farms and also the needs of different feeding stages, and the entire project is huge and complicated. Therefore, is divided into two phases of construction. Phase I construction has commenced since 2019. During the construction phase, there were impacts of competition in labor markets in domestic major electronics manufacturers, the epidemic of COVID-19, and the Russia-Ukraine war, leading to shortage in manpower and sharp increase in material and labor costs. Despite these problems, TSC still strives to overcome the difficulties and actively communicates and negotiates with various sectors to realize the ideal of combining the pig raising business with circular economy in agriculture.

          The renovation project schedule for the 13 livestock farms started from January, 2019, and the renovation project is divided into two phases, and all the 13 livestock farms are scheduled to be completed by December, 2024.

Pig-friendly rearing

          Good animal welfare is closely related to food safety and epidemic risks. The Renovation Project of Agricultural Circulation Pig Farms is not only a good solution to turn pig farming industry into an eco-friendly one, but also a global trend to improve animal welfare. The temperature control and deodorization of the comfortable negative pressure water curtain in the pig housing can greatly improve the living environment of pigs. TSC manages the pig breeding in accordance with the CPA’s Animal Industry Act and Key Points of Pig Farms Production Management. It is compliant with animal and aquatic animal transportation, loading and unloading, and slaughter regulations. In 2022, there were no violations of laws and regulations, and TSC complied with the voluntary standards. In addition, TSC continues to improve and research and develop new feed formulas. Currently, the pigs are fed “green feeds” (antibiotics-free) and the selection and breeding is carried out to produce high-quality hogs with low drug use, no pollution, and no drug residues. In addition, we also introduce the Traceability Certification for the hogs to implement food safety regulations.

          Animal friendly production operations and equipment are planned in TSC’s livestock farms. For example, the pigs are castrated within 7 days of birth. There are toys in the pig house for the pigs to play with. In the planning of new pig house in the future, the sows will only be kept in a narrow pen for one month from artificial mating for the observation of whether they are pregnant. The size of the narrow pen is designed in accordance with the EU Animal Welfare Measures or animal-friendly guidelines (1.64 m2 of activity space per sow). If the pregnancy is confirmed, during the pregnancy period of 114 days, the sows will be raised in a group breeding pen with sufficient space for activities (up to 10 sows) to wait for delivery. The farrowing pen (not a narrow pen) is also designed to be compliant with the EU Animal Welfare Measures or animal-friendly guidelines (6 m2 of activity space per sow) for the sows to have sufficient space for movement, creating a friendly environment for delivery and lactation. The design of the hog house is compliant with the EU regulations with the activity space of 1 m2 per head, providing a comfortable and pollution-free breeding environment for hogs. In the future, after the renovation of the livestock house is completed, the intelligent management system and the automated feeding system installed can further improve the breeding efficiency and enable real-time monitoring of the pigs’ health, creating a 3-win situation for the pigs, TSC, and consumers.
