Interest Inbreeding And Advantages And Disadvantages In Livestock

Crosses are inbreeding is a way that aims to find a pure strain of the descent so basically done a variety of ways to find the best strains. To get the maximum results inbreeding done by crossing a pure strain of several related breeds between generations so that the recession lethal genes that looks invisible. This will cause a shortage and kerungian miraculous.

Inbreeding is the mating between animals

Inbreeding is the mating between animals that have relatively closer kinship than the average of kinship with other animals in a population. In other words, inbreeding is a marriage between animals that have one or more common ancestor (common ancestor).

Inbreeding in cattle breeding is necessary to find a genetic advantage elders towards their children. But the degree should be limited not to do intensive continuously so that the loss due to inbreeding could not appear. As in dairy cattle, inbreeding coefficient should not reach more than 12%, since if more than 12%, then every increase of 1% would reduce the performance of the production and reproduction as well as the dairy cow health and increased mortality.

Crosses with inbreeding way has several advantages and disadvantages that would need to be known. By knowing these things, especially the loss gives us greater need to take that into account.

The following are the advantages of inbreeding:

1. Make individuals alike.
Inbreeding can cause cattle similar to each other, because inbreeding can lower heterozygotsitas levels in the population.
2. Preserving the desired properties.
If we liked a trait in a flock, these properties can be maintained by inbreeding.
3. Selection of the genes that are unwanted.
Inbreeding makes individuals homozygot. If there is lethal genes in homozygot circumstances, it would seem. Thus we can make the selection of the livestock carrier of the trait is not good.
4. It is the most excellent method to form a pure strain of herds of unknown origin.
5. Generated cattle according to desired needs.

The following is a disadvantage inbreeding:

1. The reduced number of gene pairs heterosigot, and the growing number of homozygous gene pairs.
2. Increase the frequency of homozygous recessive genotype animals, or collect genes that are less good. Some recessive lethal genes whose expression will appear when the homozygous recessive condition.
3. The high level of inbreeding that causes "pressure inbreeding" inbreeding depression) is characterized by the emergence of physical abnormalities such as short stature, abnormal jaw, and others.
4. Decreased appearance / performance of livestock.
On the chicken can create decreased egg production and increased mortality. In cattle, will lead to a decline in birth weight, vitality, weight and size and can decrease milk production and milk fat. While sheep may lead to the production of wool (quality and quantity) decreases.

Purpose and Advantages of Artificial Insemination In Livestock

Artificial Insemination

Definition of Artificial Insemination (AI) was a business man (inseminator) in inserting sperm or semen into the female reproductive tract by using insemination with the goal of keeping livestock (cows, sheep, buffalo, etc.) became pregnant. In scientific terms is called Artificial Insemination Artificial Insemination (AI) and Cement is a seminal coming from superior male cattle used for mating or artificial insemination syringe.

The IB program not only includes income semen into the female reproductive tract, but also involved the selection and maintenance of the stud, relocation, valuation, dilution, storage or preservation (refrigeration and freezing) and transport of semen, insemination, recording and determination of the insemination of animals / livestock female, guidance and counseling to farmers. Thus AI becomes wider sense which includes aspects of reproduction and breeding.

Interest Artificial Insemination
The purpose of marriage cattle with artificial insemination system are:
1. Improving the quality of local livestock.
2. Accelerate the increase in the livestock population.
3. Conserve the use of a stud.
4. Prevent sexually transmitted diseases as a result of natural mating.
5. crossbreeding between various nationalities / races do.

Advantages of Artificial Insemination

In the mating injection or AI activity in this animal gives some advantages / benefits include:

1. Cost-effective, with artificial insemination farmers no longer need to maintain the stud cattle, so that only maintenance costs incurred for breeding only.
2. Save time. Where to marry a cow, farmers no longer need to look for bulls (bull), they simply contact inseminator in their area and determine the type of seed (semen) that they want.
3. Can adjust the distance lambing / calving interval with good cattle.
4. Prevent the occurrence of inbreeding in cattle.
5. Can take advantage of technological progress is good so that sperm / semen can be stored in the long term. So this Frozen Semen can still be used for a couple of years later though males were taken stucco dead.
6. Generate a new generation of children going to producing quality meat (beef cattle) and meningkatklan milk production in dairy cattle females.
7. Improved genetic quality becomes faster.
8. Farmers can choose types / breeds desirable. For example, cattle
Limousin, Simental, Tillers Ongole, Brahman, Brangus, FH, Bali and others).
9. Birth weight was higher than the result of natural mating. This is because the cement used comes from superior males.
10. The growing possibility the child's weight faster. since produced results from superior male perkawian.

AI implementation is successful when the parent AI animals do become pregnant. Period bunting / cow gestation period (gestation period) is the period of time from the moment of conception the sperm towards the egg until the child is born. According Toelihere (1981) cow gestation period ranges from 280 up to 285 days. Once the delivery is called fallow period until the cows in question is pregnant in the next period.
