In cetaceans, there is only one report of this fetal abnormality, dated in late 1991, in a male stillborn Indo-Pacific bottlenose dolphin (Tursiops aduncus) and diagnosed using transabdominal ultrasonography on its mother that was kept under human care in the Ocean Park Corporation. After birth, physical and general radiographic examination showed kyphosis of the cervical and lordosis of the thoracic vertebrae, narrowed triangular skull base, thickening of an undersized maxilla, cranial vault defect including the absence of the bones constituting the roof of the cranial cavity.

The scans were then used to conduct virtual necropsy (virtopsy) for detailed gross morphological analyses of the malformation. CT confirmed the total absence of the interparietal bone but also revealed the presence of greatly reduced other bones.

Although ultrasound is an established method to monitor pregnancy, fetal growth and wellbeing, virtopsy provided a more accurate characterization of the bone and neural malformations postmortem.

A lot of studies have been conducted to evaluate the influence of most of the above factors on welfare of dairy animals, but very little studies focused on the influence of stockpeople KAPs of animal welfare. However, given the growing demand for milk and dairy products and the increasing global demand for animal products that are produced in an animal welfare friendly environment there is potential benefit of studying the KAPs of stockpeople towards the welfare of dairy animals. Herein, a cross sectional study involving 93 stockpeople from the 31 large-scale dairy farms in Midlands Province, Zimbabwe was conducted to determine their KAPs on animal welfare. Results of this study revealed that 67% of the stockpeople could not define animal welfare and this was significantly associated with the stockperson's level of education (χ2 = 12.54, df = 3, p = 0.006). Only 14% of the stockpeople interviewed always talked to dairy animals when handling them and this was correlated with gender (p < 0.001). About 20% of the stockpeople responded positively to touching the dairy animals when handling them and this was associated significantly with the stockperson's gender (p = 0.005). On a more positive note when stockpeople were asked to respond to whipping of animals when driving them, about 90% of the stockpeople said they never whip animals when handling or driving them. It is recommended that further studies be done to find out better and more effective ways of teaching animal welfare concepts and practices. These approaches of teaching animal welfare to stockpeople should take into account the stockpeople's cultural, religious and education backgrounds.

A structured questionnaire was administered to 335 dog owners to assess their knowledge, attitudes and perceptions related to the risk factors for transmission, control, and prevention of CE.
