Achieving controlled and planned pregnancies
Avoiding the use of semen evaluation
Which method of semen collection is preferred when working with larger animals like horses?
Electro-ejaculation
Massage method
Artificial vagina
Recovery of semen from the vagina
In which method is manual stimulation used to induce ejaculation in males?
Electro-ejaculation
Massage method
Artificial vagina
Recovery of semen from the vagina
Describe the main purpose of artificial insemination and its advantages.
The main purpose of artificial insemination is to achieve controlled and planned pregnancies in animal breeding. This technique allows for selective breeding to improve genetic traits, increase breeding efficiency, and manage reproduction more effectively.
Explain the process of collecting semen through the artificial vagina method.
The artificial vagina method involves stimulating a male animal to ejaculate into a specially designed device. The collected semen is then processed, evaluated for quality, and used for insemination.
Under what circumstances might electro-ejaculation be necessary in animal breeding?
Electro-ejaculation may be necessary when natural ejaculation is not possible due to physical limitations or medical conditions in the male animal.
How does artificial insemination contribute to genetic improvement in livestock breeding?
Artificial insemination allows breeders to carefully choose which males and females to mate, resulting in the propagation of desired genetic traits and improved livestock populations.
