artificial breeding technician Interview Questions and Answers

1. What is artificial insemination (AI)?

   • Answer: Artificial insemination is a reproductive technology where semen is collected from a male animal and artificially introduced into the reproductive tract of a female animal to achieve pregnancy, bypassing natural mating.

2. Describe the process of semen collection in cattle.

   • Answer: Semen is typically collected using an artificial vagina (AV) which mimics the conditions of the female reproductive tract. The bull mounts a dummy and ejaculates into the AV. The collected semen is then evaluated for volume, motility, and concentration.

3. How do you evaluate semen quality?

   • Answer: Semen quality is assessed through several parameters: volume, concentration (sperm per milliliter), motility (percentage of moving sperm), morphology (percentage of normal-shaped sperm), and viability (percentage of live sperm).

4. What are the different methods of semen processing and storage?

   • Answer: Semen processing involves extending the semen with a diluent to increase volume and provide nutrients. Storage involves freezing the extended semen in liquid nitrogen for long-term preservation or short-term refrigeration at 4-5°C.

5. Explain the procedure of artificial insemination in cows.

   • Answer: The cow is restrained, the rectum is palpated to locate the cervix, and a insemination gun containing the thawed semen is carefully passed through the cervix into the uterus. The semen is then deposited.

6. What are the signs of estrus (heat) in cows?

   • Answer: Signs of estrus include restlessness, mounting other cows, bellowing, clear mucus discharge, and a swollen vulva. A cow in heat will stand to be mounted.

7. What is the importance of accurate record-keeping in AI?

   • Answer: Accurate records are crucial for tracking breeding performance, identifying successful matings, managing herd genetics, and troubleshooting breeding problems.

8. What are some common problems encountered during AI?

   • Answer: Problems include difficulty locating the cervix, improper semen handling, inaccurate heat detection, and uterine infections.

9. How do you maintain hygiene and sanitation during AI procedures?

   • Answer: Strict hygiene is maintained through hand washing, disinfection of equipment, using sterile gloves and materials, and maintaining a clean working environment to prevent the spread of infection.

10. What are the ethical considerations in artificial breeding?

    • Answer: Ethical considerations include animal welfare, responsible genetic selection, and preventing the spread of diseases.

11. What are the advantages of artificial insemination?

    • Answer: Advantages include improved genetic selection, increased reproductive efficiency, disease control, and cost-effectiveness.

12. What are the disadvantages of artificial insemination?

    • Answer: Disadvantages include the need for skilled technicians, potential for injury to animals, and the risk of spreading diseases if proper hygiene isn't maintained.

13. What is embryo transfer?

    • Answer: Embryo transfer involves collecting fertilized embryos from a donor female and transferring them into a recipient female for gestation and birth.

14. Describe the process of embryo collection and transfer.

    • Answer: Embryos are collected non-surgically using a specialized catheter, graded for quality, and then transferred into the uterus of a recipient female using a similar catheter. Synchronization of estrus cycles between donor and recipient is crucial.

15. What are the benefits of embryo transfer?

    • Answer: Benefits include maximizing the reproductive potential of superior females, increasing the genetic improvement rate, and expanding the use of valuable genetics.

16. What is in vitro fertilization (IVF)?

    • Answer: In vitro fertilization is a reproductive technology where eggs are retrieved from a female, fertilized with sperm in a laboratory setting, and the resulting embryos are then transferred into the uterus.

17. What are the differences between AI and IVF?

    • Answer: AI involves inseminating the female with semen directly, while IVF involves fertilizing eggs in a laboratory setting before transferring the embryos.

18. What safety precautions should be taken when handling semen and embryos?

    • Answer: Precautions include using appropriate personal protective equipment (PPE), maintaining sterile conditions, and following proper disposal protocols for biohazardous materials.

19. What are some common reproductive diseases in livestock and how can they impact AI success?

    • Answer: Diseases such as brucellosis, leptospirosis, and bovine viral diarrhea (BVD) can negatively impact fertility and the success of AI. Proper biosecurity measures are crucial to prevent disease transmission.

20. How do you manage and troubleshoot breeding problems in a herd?

    • Answer: Troubleshooting involves reviewing breeding records, assessing reproductive health through physical examinations, conducting diagnostic tests, and implementing appropriate management strategies, such as nutritional adjustments or disease control.

21. What are the different types of diluents used in semen processing?

    • Answer: Several diluents are available, each with different compositions designed to protect and nourish the sperm during storage. Examples include egg yolk-based diluents and commercially available extenders.

22. What is the importance of proper thawing techniques for frozen semen?

    • Answer: Rapid and controlled thawing is crucial to minimize sperm damage during the thawing process, maximizing sperm motility and viability.

23. What are the legal and regulatory aspects related to artificial breeding?

    • Answer: Regulations vary by location but often include licensing requirements for technicians, semen import/export regulations, and animal health and welfare standards.

24. How do you stay updated on the latest advancements in artificial breeding technologies?

    • Answer: Staying updated involves attending conferences, reading scientific literature, participating in professional organizations, and networking with other professionals in the field.

25. What are the potential risks associated with using AI?

    • Answer: Risks include injury to animals during the procedure, introduction of disease, and failure to achieve pregnancy.

26. How do you handle a situation where a cow shows signs of infection after AI?

    • Answer: Immediate veterinary attention is necessary. The cow would be treated with antibiotics and monitored closely. Proper biosecurity measures will be implemented to prevent further spread of infection.
