Artificial Insemination in Cattle : Everything You Need to Know About AI in Cows and Buffaloes
Artificial Insemination (AI) in Animals
Artificial insemination (AI) is a technique used for the improvement of animal breeds. In this process, semen collected from a male animal with high reproductive capacity is artificially deposited into the reproductive organs of a female animal when she is in heat (the suitable time for conception). This procedure is known as artificial insemination.
AI is used not only for breed improvement but also to enhance milk and meat production by utilizing the traits of high-quality male bulls. Currently, the use of artificial insemination is more prevalent than natural breeding, as natural breeding increases the risk of congenital and sexually transmitted diseases, such as brucellosis and trichomoniasis. In contrast, the likelihood of spreading these diseases through artificial insemination is nearly zero.

History of Artificial Insemination (AI)
First AI in the World: The first artificial insemination in animals was performed in Italy. In 1780, Lazzaro Spallanzani from Italy conducted the first artificial insemination on a dog, resulting in the birth of three puppies.
First AI in India: The first artificial insemination in India was carried out in 1939 by Dr. Sampat Kumaran at the Palace Dairy Farm in Mysore, Karnataka, using the semen of a Holstein Friesian (HF) bull in a Helikar cow.
First AI in Buffaloes: Artificial insemination in buffaloes was first performed in 1943 by the Allahabad Agricultural Institute.
First AI in Humans: The first artificial insemination in humans was conducted in 1770 by Scottish surgeon John Hunter, who later informed the world about this technique in 1790.

What is Artificial Insemination (AI)?
Artificial insemination (AI) is a technique used for the improvement of animal breeds. In this process, semen collected from a male animal with high reproductive capacity is artificially deposited into the reproductive organs of a female animal when she is in heat (the suitable time for conception).
Advantages of Artificial Insemination
- Utilization of High-Fertility Males:
Artificial insemination (AI) allows for the better utilization of high-fertility males. For instance, it may not be feasible to breed a superior Murrah bull from India with buffaloes in America through natural breeding, but the bull's semen can be collected and used for artificial insemination to impregnate those buffaloes.- Breed Improvement:
AI technology can improve animal breeds, resulting in the generation of high-quality breeds that are better in production capacity and health.- Increased Production:
By spreading the traits of a high-quality male through artificial insemination, both milk and meat production can be increased, leading to higher profits for farmers.- Prevention of Venereal Diseases:
Venereal diseases that spread through natural breeding, such as brucellosis and campylobacteriosis, can be prevented through artificial insemination. By mixing antibiotics in the semen, the spread of these diseases can be curbed, ensuring the health of calves.- Semen Collection and Distribution:
Semen can be stored and sent as semen straws to rural and urban areas, allowing for easier and problem-free artificial insemination.- Better Breeding Records:
Artificial insemination facilitates easier record-keeping of breeding, helping to monitor breeding rates and the birth of calves.- Utilization of Disabled Males:
High-quality semen from disabled males can also be utilized through artificial insemination, maximizing their potential.- Breeding of Animals of Different Sizes:
Artificial insemination can successfully breed animals of varying sizes.- Herd Improvement:
The overall traits of a herd can be enhanced through AI, improving its quality.- Use of Semen from Deceased Animals:
Semen from bulls can still be used for artificial insemination even after their death, allowing their high fertility potential to continue benefiting the breeding program.- Time Savings in Progeny Testing:
Progeny testing can be conducted in less time with artificial insemination, enabling faster implementation of animal improvement programs.- Reduced Injury Risk:
Cows and buffaloes impregnated via AI have a lower risk of injury compared to those bred naturally.Disadvantages of Artificial Insemination
- Need for Training:
Successful artificial insemination requires trained veterinarians or animal inspectors and specialized equipment.- Risk of Infection:
If the bull from which the semen is collected is infected with brucellosis and the semen is not properly tested, all cows and buffaloes inseminated with that semen could also become infected.- Timing of Heat:
If the semen is not deposited at the correct time during the female animal's heat cycle, the success rate of insemination decreases.Methods of Artificial Insemination in Animals
The following methods are used for artificial insemination in various animals:
- Cows and Buffaloes: Recto-Vaginal method
- Mares (Horses): Vaginal method
- Sheep and Goats: Vaginal Speculum method
- Sows (Pigs): Cork Screw Pipette method
- Bitches (Female Dogs): Vaginal Insemination, Trans-Cervical Insemination, and Surgical Insemination
The Cork Screw Pipette method is used for artificial insemination in sows because the shape of the sow's cervix resembles that of the corkscrew pipette, making conventional artificial insemination difficult.
Process of Thawing
The thawing process is carried out before preparing the AI gun. Frozen semen, at a temperature of -196°C, is thawed and made viable by raising its temperature from -196°C to +37°C. To achieve this, the semen straw is held in a bucket of water at 37°C for 30 seconds, allowing the temperature to rise rapidly from -196°C to +37°C. This entire process is referred to as thawing.
- Thawing Time and Temperature: 37°C / 30 seconds
Loading of AI Gun
Cleaning the Semen Straw:
The thawed semen straw is thoroughly cleaned with a cloth to ensure that all water is removed from its surface.Loading the Semen Straw into the AI Gun:
When loading the semen straw into the AI gun, the factory seal is placed inside the gun, while the laboratory seal remains visible outside. It is cut at a 90-degree angle with a straw cutter to ensure proper deposition of the semen.Applying the Sheath to the AI Gun:
After inserting the semen straw into the AI gun, the cut end of the sheath is carefully placed onto the gun. Care should be taken not to touch the outer part of the sheath, as this could increase the risk of infection.Locking the Piston of the AI Gun:
The sheath is locked onto the piston at the lower end of the AI gun, making it ready for artificial insemination.Immediate Use of the AI Gun:
After preparing the AI gun, artificial insemination should be performed within 5 to 10 minutes. Delaying this could affect the quality of the semen.
Artificial Insemination in Cattle
The Recto-Vaginal method is used for artificial insemination in cows and buffaloes. This is the simplest and most effective method for artificial insemination in these animals, and the process is carried out in the following steps:
Controlling the Animal:
First, the cow or buffalo is restrained using a truss (special restraining device). If a truss is not available, the animal is tied to a tree or strong structure to prevent it from escaping and to ensure safety.Use of Sleeve and Lubricant:
The veterinarian performing the artificial insemination wears a sleeve on their hand and uses liquid paraffin or mustard oil as lubricant.Inserting the Hand into the Rectum:
The veterinarian then slowly inserts their hand into the rectum, forming a cone shape with their fingers and thumb. This is done because the reproductive organs are slightly to the right, and they can be easily felt and grasped with the left hand.Cleaning the Rectum and Grasping the Cervix:
After inserting the hand into the rectum, any feces present are removed. The veterinarian then feels for and grasps the cervix of the uterus.Entering the AI Gun:
After grasping the cervix, the AI gun (which is already filled with semen) is slowly inserted through the animal's vagina at an angle of about 45 degrees, ensuring it does not touch anything.Depositing Semen in the Mid-Cervix:
After entering, the semen is deposited in the mid-cervix (the middle part of the uterus). Keeping the semen in the mid-cervix enhances the motility of the sperm and allows for quicker access to the egg, increasing the chances of fertilization.Removing the AI Gun and Cleaning:
After depositing the semen, the hand in the rectum and the AI gun are slowly removed. The AI gun is then carefully checked to ensure there is no blood or other fluid on it.Disposal of Sleeve and Sheath:
After removing the AI gun, the used sleeve and sheath are disposed of to prevent reuse.Monitoring the Animal's Heat Cycle:
After artificial insemination, it is important to monitor the animal until the next heat cycle. If the cow or buffalo comes into heat again after artificial insemination, it indicates that she has not become pregnant. If she does not come into heat, it is assumed that she is pregnant.
Artificial Insemination in Sheep and Goats
The Vaginal Speculum method is used for artificial insemination in sheep and goats. In this process, the animal inspector inserts a lubricated speculum into the vagina and grasps the cervix of the uterus. The semen is then deposited in the mid-cervix.
Artificial Insemination in Mares
The vaginal method is primarily used for artificial insemination (AI) in mares. Initially, the mare is properly restrained to ensure the safety of the animal technician performing the AI. Once secured, the vulvar lips near the mare's vagina are thoroughly cleaned. Following this, the inseminating technician washes their right hand with soap and water and then rinses it with a saline solution.
Holding the insemination catheter in hand and bringing all fingers together, the catheter is inserted into the mare's vagina. After locating the external opening of the cervix (orificium externum), the technician gently advances the catheter through the vagina with the help of their left hand, ensuring that the tip of the catheter reaches the uterus through the cervix.
Artificial Insemination in Sows
For artificial insemination (AI) in sows, the cork screw pipette method is predominantly used. This method is preferred because the shape of the sow's cervix resembles that of a cork screw pipette, making it difficult to perform standard artificial insemination techniques.
Artificial Insemination in Bitches and Queens
In bitches and queens, artificial insemination (AI) primarily utilizes vaginal insemination, trans-cervical insemination, and surgical insemination methods.
