        Each case of dystocia is a clinical problem that may be solved if a correct procedure is followed. The diagnosis and treatment of dystocia requires a good understanding of normal parturition and sensitivity to the welfare of both dam and offspring. Difficult birth will occur when the expulsive forces are insufficient, when the birth canal is of inadequate size and shape, or when the presenting diameter of the fetus is unable to pass through the normal birth canal because it is too large or its disposition prevents it from doing so. The incidence of dystocia in heifers has been calculated to be anywhere from three to ten times that of multiparous cows, whether in beef or dairy cattle. Risk factors for dystocia are fetal-dam disparity, abnormal fetal position, vulval, vaginal, or cervical stenosis and uterine torsion. Preventing dystocia, particularly in first-calf heifers, is a very important component of a successful reproductive program on any dairy or beef operation and there are numerous factors have been involved in the incidence of dystocia. Even when plans are in place to limit dystocia risk to an acceptable level (<15% for heifers, <5% for cows), there are still cases of dystocia in beef and dairy herds. One of the most important fundamentals for optimum dystocia management is for the owner to know when to intervene or call for assistance. Manuscript profile

        2 - Maternal Dystocia: Causes and treatment

        Maternal dystocia includes defects of the birth canal and defects of the expulsive forces. Defects of the birth canal would be due to the pelvic constriction, failure of cervical dilation, incomplete relaxation of the caudal vagina and vulva and other physical abnormalities causing obstruction such as remnants of the paramesonephric ducts. The expulsive force of labour is due to a combination of myometrial contractions and straining induced by the contraction of the abdominal muscles with a closed glottis. Because the abdominal muscles do not come into play until the myometrium has forced the fetus and fetal membranes into the pelvic canal and stimulated the pelvic sensory nerve receptors, it is logical to consider first the expulsive deficiencies that may arise in the myometrium. These may occur spontaneously or dependently and are called, respectively, primary and secondary uterine inertia. Manuscript profile

        The aim of manipulative procedures in the monotocous species must always be to ensure that the fetus is in normal disposition before attempting delivery. Correction of defects of presentation, position, and posture can be achieved only by intrauterine manipulation of the fetus. Retropulsion of the fetus into the uterus is essential for repositioning it. After diagnosing the cause of dystocia and deciding on a plan of action, the obstetrician should consider whether the available facilities are appropriate, and whether the equipment is adequate to carry out the treatment successfully. In severe forms of dystocia, the veterinarian should always seek the assistance of a professional colleague and consider whether it might be appropriate to transport the animal to a place with hospital facilities, provided that the animal is in a fit state to travel. Obstetrical manipulation per vaginam should be performed as cleanly as possible. It is impossible to perform them aseptically because there will inevitably be some contamination. Manuscript profile
