Artificial Insemination in Goat

Introduction

The chances of inception after Artificial Insemination in different species of animal (goat, dogs, cows) varies. In dogs it is 50%, in Cows its 60% and in Goat it is 80% (In sheep Artificial Insemination is not possible) the highest conception rate is in pigs. It is above 90%. There is a ban on the import import of animals in India, the cost live animal is very high, which a farmer can not afford.

These goats are very home sick, they can not be shifted by their native place to some other place because of temperature humidity factor and the internal and external parasites. Northern Indian goats may not be suitable for hot climates of Southern India, whereas the south Indian breed are custom to live in hot climate do not survive in the northern India.

However, there are certain breeds like Barbari, and Sirohi which are stall-fed and can be kept in different climates. In India most of the goats are meat type which are producing 100 liters of milk in 100 days. The milk breed of goats are producing about 4 liters of milk per day of which Saanen and Anglo Nubian are Spread all over the world. These goats have a lactation period of 260 in Saanen, and Anglo Nubian is 350 days (almost one year).

Our Desi cows, are also producing 2-3 liters of milk per day, for a period of 100-150 days. So it is wise to incorporate Saanen goat in Himalayan Region because in their native place in Switzerland they are comfortable between 2-25°C.

The Anglo Nubian goat is a crossbred between British goat and Jamunapari, and is suitable to tolerate high temperature. Out of meat producing goat the Boer goat is the only goat which have got a fastest growth rate and can be kept in every type of climate. To pre-cure these goats is costly affair. However, the frozen semen of these breeds may be important and 50,75,80% crosses may be produce while inseminating Sirohi, Beetal, and Jamunapari Goats.

The Boer goat semen is available in Nimkar near Pune. It costs about a 100 rupees per straw and this is used by many farms. Artificial Insemination in goats meet a little training but its instrument will inseminate are the same that are used in cow insemination. The Artificial Insemination in goat will overcome the problem of inbreeding and maintenance of the high quality males.

When bucks are kept they releases Pheromones, in breeding season which gives a very unpleasant smell for which is objected by neighbors. Use of hormones in the control breeding of goats is quit cheap and can be used.

The method of Artificial Insemination

Equipment’s for Insemination with Frozen Semen

• Liquid nitrogen tank
• Speculum (25 x 175 mm for doelings or 25 x 200 mm for does)
• AI light or headlight
• Straw tweezers
• Sterile lubricant (non-spermicidal)
• Insemination gun (for straws)
• Breeding stand or facilities to restrain the doe
• Thaw box
• Paper towels
• Straw cutter
• Thermometer

These supplies can be obtained from several livestock supply companies.

Insemination Procedure

After the doe is restrained, the semen is thawed and the insemination gun is prepared. Remove the frozen straw from the liquid nitrogen tank with the straw tweezers and place it in a thaw box filled with warm water (95ºF) for 30 seconds. After thawing, dry the straw thoroughly with a paper towel. Semen must be kept warm and must not be exposed to sunlight or water during the thawing and inseminating process to prevent damaging or killing sperm cells.

Pull the plunger back 4 to 6 inches on the insemination gun and place the straw into the gun with the cotton plug toward the plunger. After the straw has been secured in the gun, the sealed end of the straw must be cut off with the straw cutter. The cover sheath should now be placed over the insemination gun and secured with an O ring.

The next step is the actual insemination process. It may be necessary to lift the doe’s hindquarters if she will not stand. If working alone, hold the insemination gun in your mouth, or have an assistant hand the insemination gun to you at the appropriate time.

Turn your headlight on. Lubricate the speculum with a non-spermicidal lubricant. Clean the doe’s vulva with a dry paper towel and insert the lubricated speculum slowly into the vulva. Insert the speculum at an upward angle to prevent vaginal irritation.

Once the speculum has been inserted, visually locate the cervix. The cervix should have a red-purple color, and white mucus will be present if the doe is in heat. Center the speculum over the opening of the cervix. Insert the insemination gun into the speculum and thread it into the opening of the cervix.

Use a circular motion and slight pressure to work the insemination gun through the rings of the cervix. Do not penetrate the cervix more than 1.5 inches. It is a good idea to draw a red ring around the cover sheath of the insemination gun 1.5 inches from the tip. This mark lets you to know how far you have penetrated the cervix.

Deposit the semen slowly by pushing the plunger forward. Remove the insemination gun slowly and remove the speculum. Source : Artificial Insemination of Dairy Goats
