Entrepreneur`S Guide To Starting A Rabbit Agricultural Enterprise, Mary Maldonado
Entrepreneur`S Guide To Starting A Rabbit Agricultural Enterprise, Mary Maldonado
Agricultural Education and Communication
At San Luis Obispo, the University Cal Ploy has an Animal Science Department that offers over twenty enterprises pertaining to livestock production which “provide the environment for students to get outside the classroom and work with the animals in teams of students” (Cal Poly 2017-19). As reported from the “Animal Science Department Enterprise Class List”, the classes involved help develop technical skills by having students learn and work in active production settings with livestock such as cows, steers, pigs, lambs, goats, and chickens (Animal Science Department 2017-19). However, when compared to the livestock accounted for at a traditional county fair …

Agricultural Education and Communication
The College of Agriculture, Food, and Environmental Sciences (CAFES) mission statement and vision of the Agricultural Education and Communication Department is to develop future leaders, educators, and communicators to advance and advocate for the agricultural industry in a global economy (AGED, 2018). Student organizations, such as Agriculture Ambassadors and Agriculture Leadership Society, facilitate several outreach events to engage and excite prospective students in pursuing their higher education goals in agriculture at Cal Poly (CAFES Ag Council, 2018). In order to maintain growing student numbers, the Agricultural Education and Communication Department, specifically, the Agricultural Science major needs revamped recruiting efforts and …
Presence Of Antibiotic Resistant Salmonella Spp. In Backyard Poultry And Their Environment, Nicole Land
Presence Of Antibiotic Resistant Salmonella Spp. In Backyard Poultry And Their Environment, Nicole Land
Master's Theses
As keeping backyard poultry rises, human contact with zoonotic pathogens will increase. One such pathogen that backyard enthusiasts have exposure risks to is Salmonella spp. which may cause a potential public health threat due to its increasing multidrug resistancy. Salmonella spp. were present in 33 of 50 samples collected from 29 sites with backyard poultry coops in San Luis Obispo County during March to May in 2014. Two different Hardy-CHROME™ Salmonella Selective Media plates were used to culture and isolate positive samples of Salmonella spp.. Each positive isolate was tested for antimicrobial sensitivity to 6 standard antibiotics: Ampicillin, Bacitracin, …
Effect Of Storage Period And Treatment On The Composition And Digestibility Of Olive Pomace In Cattle, Alexis Cecilia Ulloa
Effect Of Storage Period And Treatment On The Composition And Digestibility Of Olive Pomace In Cattle, Alexis Cecilia Ulloa
Master's Theses
Utilizing local by-products can serve to significantly reduce the current feed costs for ruminant producers. The objective of this study is (1) to evaluate the effects of chemical and bacterial inoculants in combination with ensiling, on the nutritional value and ensiling compatibility of olive pomace (OP) and (2) to identify the most biologically favorable treatment and ensiling day of OP for feeding to cattle. Freshly centrifuged OP (Olivas de Oro Olive Company, Creston, CA) was treated with one of four treatments: (1) no additives (control; CONT); (2) urea applied at 5% of DM (UREA; Agrium U.S. Inc, Loveland, CO); (3) …
Modifying The Mineral Profile Of Crickets (Acheta Domesticus) Using A Supplemented Diet, Rhianne Morgan Le Maxwell
Modifying The Mineral Profile Of Crickets (Acheta Domesticus) Using A Supplemented Diet, Rhianne Morgan Le Maxwell
Master's Theses
Captive insectivores may consume invertebrates as all, or part of their overall diet. The challenge with feeding captive insectivores involves the limited number of invertebrate species that are commercially available, and the lack of key nutrients provided by these insects. Among these insects, a naturally occurring low concentration of calcium and an inverse calcium to phosphorus ratio may put insectivores at the risk of developing hypocalcemia. A strategy to correct this nutrient imbalance involves supplementing the insect diet with high concentrations of targeted nutrients – a term referred to as gut-loading. Current industry guidelines recommend feeding a supplemented diet for …
Effects Of Polydatin On In Vitro Bovine Embryo Developmental Competence, Metabolism, And Cryopreservation, Corie Marie Owen
Effects Of Polydatin On In Vitro Bovine Embryo Developmental Competence, Metabolism, And Cryopreservation, Corie Marie Owen
Master's Theses
Bovine in vitro produced embryos suffer from poor developmental competence and altered metabolism which hinders their cryotolerance. Overall, the goals of this thesis were to improve oocyte and embryo culture with the antioxidant polydatin and to optimize slow freezing procedures. This thesis was designed as three experiments, and in each experiment, oocytes were aspirated from abattoir ovaries, matured for 23h, fertilized with semen from 1 of 3 bulls, and cultured in synthetic oviductal (SOF) based medium (SCF1) in 38.5 °C in 5% O2, 5% CO2 and 90% N2. Stage 7 blastocysts were stained with Nile …
Detecting A Probiotic Product Within The Gut Of Broiler Chickens, Anneka Pisula
Detecting A Probiotic Product Within The Gut Of Broiler Chickens, Anneka Pisula
Master's Theses
As of January 2017, the U.S. poultry industry banned the use of antibiotics and now relies on alternatives such as probiotics to help protect animal health. Although probiotic use is not a new concept in the poultry industry, identifying the best combination of bacterial strains to generate an effective probiotic formula requires further investigation. This study aimed to detect a probiotic product of four bacterial strains (Pedioccoccus acidilactici, Pediococcus pentosaceus, Lactobacillus plantarum, and Bacillus subtilis) in a feeding trial with broiler chickens. Birds given the probiotic were predicted to show an improved growth performance with …
Cal Poly's Western Bonanza Junior Livestock Show Hosts First Annual Livestock Auction: The Best In The West Livestock Auction, Karl W. Montague, Tatum E. Holdener
Cal Poly's Western Bonanza Junior Livestock Show Hosts First Annual Livestock Auction: The Best In The West Livestock Auction, Karl W. Montague, Tatum E. Holdener
Agricultural Education and Communication
Through this senior project, the authors researched whether or not Cal Poly's Western Bonanza Junior Livestock Show's first ever livestock auction was viable. Through their research, they found the addition of a livestock show to be successful and something that should continue.
Improvement Of Chilling Efficiency And Product Quality Of Broiler Carcasses Using Sub-Zero Saline Solutions For Chilling, Morgan Metheny
Improvement Of Chilling Efficiency And Product Quality Of Broiler Carcasses Using Sub-Zero Saline Solutions For Chilling, Morgan Metheny
Master's Theses
Sub-zero saline solutions were evaluated for the improvement of chilling efficiency and product quality of broiler carcasses. In this study, four experiments were conducted to chill broiler carcasses using different saline solutions and chilling temperatures in the Meat Processing Center at California Polytechnic State University (Cal Poly, San Luis Obispo, CA) or in the processing plant at Foster Farms (Livingston, CA). In Experiment I, three salt concentrations and solution temperatures (0% NaCl/0.5°C, 4% NaCl/-2.41°C, and 8% NaCl/-5.08°C) were used to chill carcasses. The fillets in brine chilling at sub-zero temperatures showed lower shear forces than the fillets in 0% NaCl …
