Item type:Publication, Data-driven insights into pre-slaughter mortality: Machine learning for predicting high dead on arrival in meat-type ducks(2025-01-01); ; Mektrirat, RakthamDead on arrival (DOA) refers to animals, particularly poultry, that die during the pre-slaughter phase. Elevated rates of DOA frequently signify substandard welfare conditions and might stem from multiple causes, resulting in diminished productivity and economic losses. This study included 18,643 truckload entries from 45 farms, encompassing a total of 23,191,809 meat-type ducks sent to a single slaughterhouse in Eastern Thailand between January 2019 and December 2023. The objective of this study was twofold: first, to classify high DOA rates (≥ 0.15%) using several predictors, including season, period of the day, number of ducks per truckload, distance, duration of transportation, age, average body weight, lairage time, and temperature at the lairage area. This classification was performed using machine learning (ML) algorithms such as Least Absolute Shrinkage and Selection Operator (LASSO), Support Vector Machine (SVM), Decision Tree (DT), Random Forests (RF), and Extreme Gradient Boosting (XGBoost). Additionally, several data-sampling techniques, including oversampling, undersampling, Random Over-Sampling Examples (ROSE), and Synthetic Minority Over-sampling Technique (SMOTE), were utilized to address the issue of imbalanced data. Second, to analyze variable importance contributing to the predictive outcomes. The descriptive analysis revealed a mean DOA percentage of 0.14% (range: 0 to 22.46%, SD = 0.49). The results of the high DOA classification indicated that among all models, XGBoost-Up, XGBoost-Down, and RF-Down were the top three models, achieving the highest overall scores in evaluation metrics including Area Under the ROC Curve (AUC), sensitivity, precision, and F1-score. The primary factors contributing to the high predictive performance of the models were the number of ducks per truckload, temperature at the lairage area, and average body weight. Additionally, the duration and distance of transportation, as well as the period of transportation, were secondary factors contributing to the outcome. These factors should be further investigated to minimize losses during the pre-slaughter phase in meat-type ducks. Additionally, considering these factors when managing transportation can help create conditions that reduce duck deaths. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, The effect of different forms of selenium on fatty acid composition in broiler meat(2018-12-01); The effects of selenium (Se) in diets on fatty acid composition, lipid indices, and enzyme indexes for desaturase, elongase, and thioesterase in Pectoralis muscle of broiler chicken were investigated. A total of 360 one-day-old chicks (Arbor Acres) were randomly assigned to 2 treatments with 6 replicates, giving 30 birds per replicate. The birds were fed ad libitum in 3 feed phases of giving 2 dietary treatments comprised 0.3 ppm of inorganic Se from sodium selenite (Na-Se) and 0.3 ppm of organic Se from Zn-L-selenomethionine (Zn-L-SeMet). At 39 days of age, one bird from each treatment was randomly selected and slaughtered. Pectoralis muscles were collected and stored at -40 °C before fatty acid composition analysis. There were not significantly different between organic and inorganic selenium treatment on fatty acid composition, lipid indices, and enzyme indexes (P>0.05). However, the results demonstrated that Zn-L-SeMet had slightly lower I/A (6.7%) while had higher h/H (4.4%) and MUFA (8%) than Na-Se. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Effects of guanidinoacetic acid supplementation on productive performance, pectoral myopathies, and meat quality of broiler chickens(2021-11-01); Sitthigripong, RonachaiThe effects of guanidinoacteic acid (GAA) supplementation on productive performance, pectoral myopathies, and meat quality of broilers were studied. Treatments consisted of corn/soybean-based diets with a GAA supplement (0%, 0.06%, and 0.12%). A total of 546 one-day-old Ross-308 males were randomly allocated to 42 floor pens with 14 replicates (13 birds/pens) for each treatment. The results showed that GAA at doses of 0.06% and 0.12% improved feed conversion, increased the percentage of normal breast, and decreased the severity of wooden breast. Breast muscle myopathy severity was positively correlated with heavy birds and negatively correlated with breast muscle creatine and glycogen. Breast muscle creatine and glycogen correlated positively with normal, less severe pectoral myopathies and meat quality. In conclusion, GAA supplementation improved broiler performance without exacerbating pectoral myopathy or affecting meat quality.
