This document discusses techniques for artificial insemination in various animal species. It begins by defining artificial insemination as the introduction of semen into the female reproductive tract by means other than sexual intercourse. Advantages include genetic improvement and disease control, while limitations include needing skilled personnel and lower conception rates than natural breeding. The techniques described include recto-vaginal insemination in cows, intravaginal or transcervical insemination in does, and various methods like intravaginal, transcervical, or laparoscopic intrauterine insemination in ewes. For chickens, semen is deposited into the vagina with the bird restrained and its abdomen pressed.

3. What is AI ?
Artificial insemination is the introduction of semen into the female
reproductive tract ( vagina, cervix, uterus etc.) by some means other
than sexual intercourse.

4. Advantages of AI
1. Genetic improvement
2. Wide spread use of genetically superior sire
3. Disease control
4. Reduce cost
Limitations of AI
1. Skilled person is needed
2. Correct estrus detection is major concern
3. Conception rate is lower than the natural service

5. Technique of AI: Cow
Method
Recto-vaginal method
Steps
1. Thawing of frozen semen
2. Loading of AI gun
3. Insemination

6. Technique of AI: Doe
Method
Intravaginal
Trans-cervical
Procedures
1. The goat is placed backside upwardly
2. A vaginal speculum or a glass tube(two ends open)
is set to see the vagina or cervix
3. A loaded AI gun is inserted through the speculum
and deposit the semen in cervix or vagina

7. Technique of AI: Ewe
Method
Intra-vaginal
Trans-cervical
Intra-uterine
Transcervical intrauterine
Laparoscopic intrauterine
Above all these method Laparoscopic AI is widely used in ewes.

8. Procedures
1. Before performing AI the animal
should be restrained properly and
sedation should be done
2. Lower abdomen should be prepared by
removing the wool
3. Torcher and cannula is used to
penetrate the lower abdomen

9. 4. First one is for laparoscope to see the uterus, 2nd one is for insemination pipette.
5. The semen is placed in the uterus by penetrating it’s wall with sharp tip- of the4 insemination
pipette.
6. After performing the AI the wound should be closed with surgical staple.

10. Technique of AI: Chicken
 Bird is held by the legs with the
left hand down and tail tucked
back and against the operator
chest.
 The thumb of the right hand is
placed against the upper lip of the
vent then with a rounding motion
press the abdomen muscle.
 The insemination apparatus is
introduced into the vagina about 1
inch and semen is deposited at the
junction of vagina and uterus.
