Failure Factor Artificial Insemination

Insemination failure factors:

1. Quality Cement / Straw is ugly

    Cement of good quality for artificial insemination is a concentration of 25 million for frozen semen and Post Thawing Motility (PTM) was 40% than that spermatozoanya not have abnormalities. Spermatozoa having abnormal shape causes the loss of its ability to fertilize an egg in the fallopian tubes. For that cements evaluated periodically dive 6 months. Good quality of cement will increase the success of artificial insemination. In addition it is necessary also to know how to handle the Inseminator Semen storage in order to stay well and have good motility

2. Detection inaccuracies Estrous

    With proper detection of estrus can help operators Artificial Insemination in determining the appropriate time in doing artificial insemination. Different ways to determine estrous cow that is silent when ridden by another cow, female animals genitals swollen, tender and red, or in terms that are widely known, especially among farmers in Java, Indonesia with terms 3A, the female animals genitals looked Abang (red) , Abuh (swelling) and Anget (temperature rise). Usually slightly decreased appetite. 

3. Cow condition Females

    There are several possibilities including
Anatomical abnormalities such as the Reproductive Tract: Blocked fallopian tubes, adhesio The exchanges between ovarim with ovarian, uterine environment in a less harmonious, decreased function of the reproductive tract or the number of bacteria / microorganisms in the reproductive tract.

        
Hormonal Disorders:        Low levels of LH hormone in the blood can cause delayed ovulation (ovulation is delayed) and follicular cyst. Because of the low levels of LH, folikuker phase should be extended so that the follicles have entered the luteal phase, ovulation and delayed the time or not happen at all. Symptoms appear from this case is mating again (repeat bredeeer). In cases of anovulation (failure to ovulate), follicle de Graaf is ripe failed broken because there is impaired secretion of gonadotropin hormones FSH and LH.
        
Abnormalities of the egg:

        The imbalance of reproductive hormones can disrupt the process of ovulation. Ovulation is not normally able to produce eggs that are not normal.

        Some of the abnormal shape of the egg are:

• Egg cell degeneration
• Zona pellucida is torn or ripped
• Young eggs
• The egg-shaped flattened, oval
• Mini egg egg cell and giant cell

        Abnormalities in the egg will cause the failure of the fertilization process so that the cow that had been in Artificial Insemination is not pregnant.
