Parturition
Parturition
• What is it?– The process of
giving birth
Signs of Parturition• Distended (swollen) udder• Fluid from udder changes
from a watery solution to the thick, milky colostrum
• Muscles in the rear begin to shrink and fall away
• enlargement & swelling of the vulva
• Nervous & uneasy behavior• Muscular contractions as
labor begins
Presentation of the Fetus• The first water bag appears on the outside,
increasing in size until it ruptures due to its own weight.
• Immediately after the first water bag, the amniotic bladder (the second water bag) follows, containing the fetus.
• The amniotic bladder ruptures, straining on the female becomes more pronounced and presentation of the fetus soon follows.
Normal Presentation• The most common
presentation is as follows:– front feet first, followed
by the nose resting on them
– Shoulders
– Middle
– Hips
– Hind feet and legs• If presentation is normal & within 1-2
hours after the first signs of labor, no assistance is necessary.
Abnormal Presentation• Anterior Presentations:
– Hind feet in pelvis
– Both forelegs bent at the knees
– Head upward & backward
– One foreleg bent at knee
Abnormal Presentations
• Buttock Presentation
• Back Presentation
Abnormal Presentation
• What should be done to assist if problems occur?
Post-Partum Care
• Make sure offspring has received colostrum– What is Colostrum
• First milk containing antibodies
• Dry off offspring if the mother hasn’t after about 30 minutes
• Dip umbilical cord/navel in iodine to prevent infection
Newborn Calf• A vigorous calf will attempt to stand in about
15 minutes and will usually be nursing within 30 - 60 minutes.
• Human assistance is sometimes necessary to get a calf to begin nursing. The weaker the calf, the longer it takes for it to begin nursing.
• Clean newborn animals using appropriate resources, to ensure that they are dry. Gently remove all mucus and foreign matter from the mouth and nasal passage.
The Afterbirth
• Three to six hours after parturition the placenta is expelled. – The placenta is commonly known as the
afterbirth.
• If the placenta remains in the cow for more than 24 hours, it must be removed manually.
Supplies
• Obstetrical Chains
• Calf Puller
