Abnormal positions of calf in utero. (Figs. 1, 2, 3, and 5 from Fleming's Veterinary Obstetrics; fig. 4 after St. Cyr, from Hill's Bovine Medicine and Surgery; fig. 6 from D'Arboval, Dictionaire de Médecine et de Chirurgie.)
Fig. 1. Anterior presentation; one fore limb completely retained. The retained limb must be reached if possible and brought forward joint by joint and the fetus then extracted.
Fig. 2. Anterior presentation; fore limbs bent at knee. The limbs must be extended before delivery can be accomplished.
Fig. 3. Anterior presentation; fore limb crossed over neck. The leg should be grasped a little above the fetlock, raised, drawn to its proper side, and extended in genital canal.
Fig. 4. Anterior presentation; downward deviation of head. The head must be brought into position seen in Plate XV before delivery can take place.
Fig. 5. Anterior presentation; deviation of the head upward and backward. Retropulsion is the first indication, and will often bring the head into its normal position.
Fig. 6. Anterior presentation; head presented with back down. The fetus should be turned by pushing back the fore parts and bringing up the hind so as to make a posterior presentation.
