Studies on Intramuscular Fat Percentage in Live Swine Using Real-time Ultrasound to Determine Pork Quality
Intramuscular Fat Heritability Genetic Correlation
2016/5/17
In the modern pork industry, selection of high intramuscular fat (IMF) in pigs is necessary to improve pork quality. Ultrasound has been used previously to predict subcutaneous fat thickness and IMF i...
Effects of ketamine/xylazine premedication on emulsified isoflurane general anaesthesia in swine undergoing embryo transplantation
premedication emulsified isoflurane physiological parameters general anaesthesia pig
2015/4/17
Cardiorespiratory effects were assessed during ketamine/xylazine premedication followed by emulsified isoflurane anaesthesia in swine undergoing experimental embryo transplantation. Ketamine (10 mg/kg...
