“…21 The caudal dorsal presentation was found to be the most frequent malpresentation, and limb flexion in cranial presentation, head deviation, breech, post ventral, transverse and ventro vertical presentation were 11.4%, 2.5%, 8.2%, 1.3%, 1.3% and 0.6%, respectively, in this study. 21 Abnormal positions and postures are described for cranial (anterior) and caudal (posterior) presentations separately. The total incidence of dystocia due to fetal maldispositions described for the buffalo vary from 45.4 26 to 69.8%.…”

“…[26][27][28] A large number of risk factors for dystocia have been identified. 2,4 It has also been recognized that the introduction of large sized beef bulls like Charolais and Simmental 10,21,[29][30][31] and the Holstein Friesian bulls in dairy cows 18,32,33 has resulted in an increased incidence of dystocia, probably due to an increase in the body weight of the calf and the change in its shape. Such effects have not been documented for buffalo.…”

“…15 These anatomical differences mean that the first and second stages of labor in the buffalo can easily be completed within 20-70 min. 14,16,17 The causes of dystocia have been described from a number of perspectives; either based on analysis of a large number of calving records in dairy 8,[18][19][20] and beef cows 9,10,21,22 or on the basis of clinical findings. [23][24][25] Most reports of buffalo come from clinical data.…”

Perspectives of fetal dystocia in cattle and buffalo

We review the causes of fetal dystocia in cows and buffalo. Two fetal causes are distinct fetal oversize and fetal abnormalities. Fetal oversize is common in heifers, cows of beef cattle breeds, prolonged gestations, increased calf birth weight, male calves and perinatal fetal death with resultant emphysema. Fetal abnormalities include monsters, fetal diseases and fetal maldispositions, and it is difficult to deliver such fetuses because of their altered shape. Although monsters are rare in cattle, a large number of monstrosities have been reported in river buffalo; yet also here, overall incidence is low. Diseases of the fetus resulting in dystocia include hydrocephalus, ascites, anasarca and hydrothorax. The most common cause of dystocia in cattle seems to be fetal maldispositions, of which limb flexion and head deviation appear to be the most frequent. We provide a brief description of the management of dystocia from different causes in cattle and buffalo. A case analysis of 192 and 112 dystocia in cattle and buffalo, respectively, at our referral center revealed that dystocia is significantly higher (P<0.05) in first and second parity cows and buffalo, and that dystocia of fetal origin is common in cows (65.62%) but less frequent (40.17%) in buffalo. In buffalo, the single biggest cause of dystocia was uterine torsion (53.57%). Fetal survival was significantly (P<0.05) higher both in cows and buffalo when delivery was completed within 12 h of second stage of labor.

The obstetric assistance of dystocia in field conditions promotes greater bacterial contamination of the uterus, causing subclinical endometritis. The aim of this study was to determine the occurrence of subclinical endometritis in beef heifers receiving professional calving assistance, and to evaluate endometrial cytology as a diagnostic technique compared to uterine biopsy. A group of 829 Angus heifers were assisted at calving. Dystocia was classified based on difficulty at assistance, which was estimated as complex or simple. At the end of the calving season, 93 dystocic heifers were reported (10.7%). The percentage of simple resolution and complex resolution was 88.2% and 11.8%, respectively. After 60 days of calving, all animals underwent a gynecological examination, endometrial cytology, and uterine biopsy. In all, 38.9% of heifers presented subclinical endometritis diagnosed by endometrial cytology (sensitivity = 78.6%, specificity = 95.8%). There was a significant association (r = 0.8528) between uterine cytology and uterine biopsy. No associations were observed between endometrial cytology or biopsy and calf viability, or between endometrial cytology or biopsy and calving resolution. Endometrial cytology is a noninvasive technique with high specificity and repeatability for the diagnosis of subclinical endometritis postpartum in dystocic beef heifers.
