Bacterial contamination and antibiotic susceptibility profile of Sus scrofa domesticus semen

The fastest-growing industry among all livestock is piggery, with traditional pig farmers from the lowest socio-economic strata in charge of the pork sector and pig raising.Artificial insemination (AI) is the most widely used method for reproduction, aiming to boost fertility rates and increase supply.However, sperm quality can be negatively impacted by various factors, such as varicocele, accessory gland infection, immunological factors, and endocrine causes.Antimicrobial control in semen dosages is essential due to high storage temperatures.Ten semen ejaculates were collected from Intensive Cattle Development Project (ICDP), Upper Shillong weekly using gloved hand method from boars, mounted on dummies, and placed in pre-warmed bags and laboratory analysis was conducted in North-Eastern Hill University, Shillong and identification was confirmed at Pasteur Institute, Shillong.Pseudomonas aerugionosa is the most predominant bacterial species found in this study.Antibiotic resistance rates show 100% for Tetracycline, Ciprofloxacin, Imipenem, 90% for Gentamicin, 80% for Kanamycin, and Chloramphenicol.Understanding microorganisms and using advanced techniques like artificial insemination (AI) is crucial for improving the pig business.Breeders need a high-quality and high-quantity semen supply to improve production.Analyzing microorganisms in semen is essential for understanding the effects of collecting and storing swine semen in extenders.Monitoring diet, intake, and surroundings is crucial for boar semen utilization.Researching and boosting reproductive rates is essential for maintaining a balanced pig business.Implementing semen microbiological procedures is simple and affordable.
