Symptoms
before parturition is almost the same on all cattle, but not constant
among individual animals. Therefore, these symptoms can not be used to
predict the exact time of parturition one animal, but can be a good
indication of the approximate time of birth is expected.
In cattle the ligaments in the pelvis (beef tendons in the hip) so slack
that causes a decrease in the tendon at the back. In most cow flesh
sagging veins, indicating that parturition is likely to occur within 24
to 48 hours.
female animals genitals becomes very oedematus (swelling), loosen till 2-6 times normal size. Enlarged
udder and oedematus. Heifers on the swelling began in the fourth period
of pregnancy, the cows give birth once (pluripara) enlargement of the
udder may not be obvious 2-4 weeks before parturition.
A
white mucus, thick and sticky out of the cranial female animals genitals starting in the
seventh period of pregnancy, the mucus is more and more out of the
birth. Immediately before parturition greatly increased the amount of
mucus.
For a few hours
before parturition animals showed decreased appetite and restlessness,
wagging his tail, jerking-shooting foot, lay down and back up again.
The Stages Cattle's Chilbirth
Although parturition activity is a continuous process, but as a descriptive picture can be divided into three stages.
Normal Position of the Cattle's Partus |
This
stage is characterized by active contraction of the tendon fibers in
the wall of the womb (uterus) and widening (dilatation) of the cervix
(the cervix). This condition occurs because of hormonal changes inside
the mother before birth. Contraction of the uterus occurs every 10
minutes to 15 minutes and lasts up to 15 to 30 seconds.
The
first phase of the cow that gave birth to appear for the first time
takes longer than cows that had been childless. In the first stage is to
look at the cattle seemed restless, appetite decreased, while lying
down while standing. Towards the end of this phase of membranes
(allantochorion) appears out of the female animals genitals and then broke. Fetus has
begun to position themselves to get out of the uterus.
Second Stage
The
second phase is characterized by the inclusion of the fetus into the
birth canal is dilated, the rupture of the amniotic bag (allantois),
abdominal contractions or fetal contractions and expenditures through
the female animals genitals. During this second stage, the uterus to contract by 4 to 8
times, every 10 minutes and lasts 80 to 100 seconds. Repetitive
contractions continue and the legs of the fetus visible on the female animals genitals.
When the legs of the fetus through the female animals genitals, the bag ruptured amnion.
Increased abdominal contraction occurs in the head, shoulders and hips
of the fetus into the pelvis. When the head of the fetus into the female animals genitals,
at the time of contraction is the stomach (abdominal) is strongest in
the process of parturition. After the fetal head through the female animals genitals,
usually the parent a break for a few minutes before returning with a
strong contraction during fetal chest passes through the pelvic channel.
Immediately following the hips toward the birth canal. The second stage
of birth lasts 0.5 to 3 or 4 hours. In cattle that have been frequently
bear this stage requires only half to one hour.
Third Stage
The
third stage is the last stage of a process marked by the birth of the
fetal membranes expenditure / afterbirth (placenta) and involution of
the uterus. Removal of placenta is normally completed within a few hours
after the expenditure of the fetus. Long time required for removal of
placenta in cattle is 0.5 to 8 hours.
