Siamese fighting fish (Betta splendens) is an ornamental fish that is the first exported economically valuable fish in the country, but there is a limitation to increase the production of betta fish due to climate variability and the shortage of Thai workers. This research aims to develop 2 systems: a betta fish fry nursery system and a market-sized betta fish rearing system by using automated technology to precisely control the water quality in the system and reduce labor costs. Using precise automation consists of two systems: a minimal-waste system, which repurposes some of the waste generated from farming, and a zero-waste system, which treats and recycles all wastewater from farming. These systems aim to address issues related to water quality, animal welfare, and labor requirements in Betta fish farming. Experimental results show that these systems improve Betta fish survival rates by 10-15% compared to traditional methods. When considering net returns, the zero- waste system provides the highest profitability.
ในการเพาะเลี้ยงปลากัดประกอบด้วย ระบบอนุบาลลูกปลากัด เป็นการเลี้ยงลูกปลากัดในบ่อปูนซีเมนต์ขนาดเส้นผ่านศูนย์กลาง 60-80 เซนติเมตร มีการเพิ่มระดับน้ำแทนการเปลี่ยนถ่ายน้ำสัปดาห์ละ 5-10 เซนติเมตรจากระดับน้ำเดิม และการเลี้ยงปลาขนาดตลาด เป็นการเลี้ยงปลากัดในขวดแบนเรียงต่อกันจำนวนมากบนพื้นคอนกรีต มีการให้อาหารหรือเปลี่ยนถ่ายน้ำโดยใช้แรงงานคน 1 คนต่อการเลี้ยงปลากัด 10,000 – 40,000 ตัว ดังนั้นระบบอนุบาลและการเลี้ยงปลากัดขนาดตลาดแบบพัฒนาใหม่โดยใช้เทคโนโลยีในการควบคุมคุณภาพน้ำ การให้อาหารและการเปลี่ยนถ่ายน้ำด้วยระบบอัตโนมัติ จะช่วยแก้ปัญหาอัตราการตายของปลา การใช้แรงงาน และยังสามารถเพิ่มอัตราการรอดของลูกปลากัดได้อีกด้วย

This research gives a comprehensive overview of the use of antibiotics in livestock production, highlighting both the benefits and the risks associated with their use. The benefits, such as improving immunity, digestion, and reducing infections, are contrasted with the growing concern over antibiotic residues and the development of drug resistance. The shift towards alternatives like probiotics is explored as a sustainable solution, with a specific focus on lactic acid bacteria (LAB) found in the digestive systems of livestock. Thailand’s regulations, which control antibiotic use in animal feed, are also discussed, setting the stage for the study on LAB as a potential replacement for imported probiotics. 1. Use of Antibiotics in Livestock: Antibiotics have been used to promote growth, improve digestion, and prevent infections in livestock. However, the improper use of antibiotics can lead to residues in animal products and the development of drug-resistant bacteria. 2. Global Trends in Antibiotic Use: Many countries, like the European Union and Japan, have banned antibiotics as growth promoters, while others, like China and the U.S., are planning similar bans. 3. Thailand's Approach: Thailand has implemented a regulation since September 2020 to control the use of antibiotics in animal feed, requiring control at both feed mills and farms that mix their own feed. 4. Probiotics as an Alternative: Probiotics, particularly lactic acid bacteria (LAB), are being studied as an alternative to antibiotics. LAB are naturally found in the digestive tracts of livestock and are considered beneficial for maintaining gut health and replacing the need for antibiotics. The study examines the potential of LAB from Thai livestock (broilers, pigs, and cattle) as a sustainable alternative to imported probiotics, aiming to overcome issues like low survival rates of foreign probiotics in practice.

This study aims to investigate the co-encapsulation technique of vitamin C and coenzyme Q10 within liposomes to enhance their stability and encapsulation efficiency and evaluate their antioxidant activity and release behavior under simulated gastrointestinal conditions. Liposomes were prepared using the High-Speed Homogenization Method, and their characteristics, including particle size, zeta potential, encapsulation efficiency, and antioxidant activity, were analyzed using DPPH, ABTS, and FRAP assays. The results demonstrated that co-encapsulation significantly improved the stability of vitamin C and coenzyme Q10 compared to single encapsulation. The liposomes exhibited high encapsulation efficiency and maintained strong antioxidant activity. The release profile under simulated gastrointestinal conditions also indicated a sustained and controlled release. These findings highlight the potential of the co-encapsulation technique in enhancing the efficacy of functional bioactive compounds, making it applicable to the food and nutraceutical industries.
