Progress 08/01/23 to 07/31/24
Outputs Target Audience:The target audience would be the meat and poultry scientists in academia and the poultry industry who are working on poultry production and processing. In addition, the people in the algae industry for production and utilization will be the target audience. Poultry consumers who look for good safety and quality meat would be the ultimate target audience. Changes/Problems:One student did not complete the meat industry tours due to a medial issue and another student was replaced with an alternative. What opportunities for training and professional development has the project provided?Throughout the year, students received extensive training and professional development opportunities in line with the project schedule. All undergraduate students gained hands-on experiences and collaborated with graduate students and a postdoctoral researcherduring sample collection and subsequent analysis. They also developed professional connections during industry tours and virtual meetings with USDA personnel. Students were equipped with the certification of HACCP, poultry production, and poultry processing skills. Graduate students developed their leadership skills by supervising undergraduate participants in the project activities. Key experiences included: Poultry ban preparation - broiler floor pen, experimental unit, and feed including diet formulation for starter, grower, and finisher. Algae production - media preparation, inoculation, and weight calculation. Broiler production - bird weight, feed consumption, and feed conversion rate. Broiler transportation - following the guidelines of institutional animal care and use committee (IACUC). Broiler processing - shackling, stunning, bleeding, defeathering, evisceration, and chilling. Chilling evaluation - chilling efficiency and chilling yield using traditional and innovative methods. Carcass evaluation - muscle pH, sarcomere length, shear force, and visual defects. Microbiological assessment - evaluating the populations of total plate count, E. coli, coliforms, and Salmonella. Sensory attribute - evaluating consumer sensory attributes of broiler fillets. Industry tour - visiting 7 industry plants and farms in California, and 3 industry/academic plants in North Carolina. HACCP - receiving the certification of HACCP for all students. Mentor/Mentee - receiving one-on-one mentor/mentee activity from 5 mentors. How have the results been disseminated to communities of interest?The unique results of broiler production using algae supplements and broiler processing using an innovative method have been disseminated through conference presentations. Five oral and poster presentations have been made in the national and international conferences such as The 2024 Poultry Science Association, The 100th Pacific Egg and Poultry Association, and The 36th CSU Biotechnology Symposium. What do you plan to do during the next reporting period to accomplish the goals?To accomplish the goals for the upcoming reporting period, student recruitment will begin late this year, and new students will be confirmed for year-long training. The training will focus on boiler production and processing, with students raising young chicks and processing market size broiler during summer. Additionally, students will participate in meat industry study tours in California during winter break and in another state during summer vacation. They will also receive training for HACCP certification and engage in one-on-one mentor and mentee activities.
Impacts What was accomplished under these goals?
Student Recruitment At the beginning of the spring semester, recruitment flyers were distributed, and students were selected based on their application materials, resumes, and interviews conducted by staff at Allen Hancock Community College, Cuesta College, Modesto Junior College, and Cal Poly. The selected participants include one male and four female students (three from underrepresented group). Poultry Unit, Feed Preparation, and Algae Growth Students prepared broiler pens with wood shavings, set up experimental units, and formulated corn/soybean meal diets with and without algae supplement (Uronena or Spirulina) at 0%, 2.5%, and 5%. The diets were formulated for starter (1 - 14 days), grower (15 - 28 days), and finisher (29 - 42 days). They also gained hands-on experience in algae media preparation, inoculation, and growth on a small scale. Broiler Production A total of 700 one-day-old broiler checks (350 per algae) were vaccinated, transferred, and sorted into 26 pens (18 pens/algae, 15 broilers/pen). Students shared their responsibility for caring for birds twice per day for feed, water, and health at the Cal Poly poultry unit. Each time, feeders were filled, sick and dead birds were removed, and appropriate temperature and light were ensured. Once a week, live birds were weighed, feed consumption was recorded, and feed conversion rate was calculated. Broiler Processing At 42 days of age, feed was withdrawal for 8 hours, birds were placed into crates, and transferred to the Cal Poly Meat Processing Center (MPC). At the MPC, students were trained on how to process live birds using standard processing methods such as shackling, stunning, bleeding, scalding, defeathering, and evisceration. Carcasses were then chilled using either a traditional water immersion chilling method or an innovative subzero saline chilling method. During chilling, students measured chilling time, hot carcass weight, chilled carcass weight, and chilling yield. After chilling, students measured the color of breast skin and skinless breast. After fabrication, breast fillets were used to evaluate muscle pH, sarcomere length, cooking yield, and shear force for meat tenderness. Meat industry tour and USDA Livestock & Poultry Program During the winter break, students participated in a meat industry and study tour in California such as Foster Farms (broiler and turkey processing), Alpha Inc (poultry farm/processing equipment), Denaire (squab huts), certified meat products (meat/poultry processing), Courage Production (sausage, hot dog), and Abco Laboratories (spice extract and mixture). During the summer break, students participated in an additional meat industry and study tour in North Carolina for Morris Associates (poultry equipment production), BioResource International, Inc (poultry feed ingredients), and Poultry Science Department at North Carolina State University. They also attended virtual meetings with USDA Livestock & Poultry Program staff in California and North Carolina to gain insight into agricultural marketing and industry standards. Mentor/mentee and HACCP Students completed an intensive four-day training program to achieve HACCP certification through the International HACCP Alliance. They engaged in one-on-one sections with professionals from academia, industry, and USDA to discuss career development, professionalism and leadership skills.
