“…Os DCs podem ser hereditários ou terem causas infecciosas ou ambientais, ou ocorrerem por uma interação de ambos, agindo em um ou mais estágios do desenvolvimento fetal (Leipold & Dennis 1986, Cítek et al 2009). A ocorrência de casos de DCs com aumento gradual no nú-mero de animais afetados, associado ao uso contínuo dos mesmos reprodutores em rebanho de uma única origem está relacionada à doença hereditária por genes recessivos.…”

Cases of congenital defects (CDs) in cattle diagnosed at the Laboratory of Veterinary Pathology of the Federal University of Santa Maria from 1964 to 2010 were reviewed. During the studied period tissues collected from the necropsy of 7,132 cattle were examined and 31 calves (0.4%) with CDs were found. These CDs were classified into 34 different types and ascribed to the body system primarily affected. [2], and ventricular septal defect [1]); four (7.5%) affected the lymphatic system and consisted of inherited hypoplasia or aplasia of lymphatic vessels and lymph nodes associated with lymphedema. Two cases (3.0%), of hypotrichosis were observed affecting the integument; one case (1.9%) of tracheal stenosis was found in the respiratory system and one case of goiter (1.9%) involved the endocrine system. The results of this survey inidicate that the majority o CDs in cattle in the central Rio Grande do Sul are sporadic; nevertheless their continued study is important for determining the etiology and control.

“…In this species, the CDC73 gene is assumed to be responsible for the malformation [ 36 ]. In cattle this condition is the most frequently noted congenital disorder [ 37 ] and it seems to be associated with genes located at the centromeric end of BTA8 [ 38 ]. Additionally, this is the most common malformation in river buffalo, but only a few cases are well described in the literature, like in the Pandharpuri buffalo breed in which Amle et al [ 39 ] found a male calf with incomplete closure of umbilicus and reducible intestinal hernia associated to cryptorchidism, and in MIRB, in which Correale and Consalvo [ 9 ] found 72 cases with different phenotypic traits.…”

Simple SummaryCongenital malformations (due to genetic causes) represent a hidden danger for animal production, above all when genetic selection is undertaken for production improvements. These malformations are responsible for economic losses either because they reduce the productivity of the farm, or because their spread in the population would decrease the total productivity of that species/breed. River buffalo is a species of increasing interest all over the world for its production abilities, as proved by the buffalo genome project and the genetic selection plans that are currently performed in different countries. The aim of this review is to provide a general view of different models of congenital malformations in buffalo and their world distribution. This would be useful either for those who performed buffalo genetic selection or for researchers in genetic diseases, which would be an advantage to their studies with respect to the knowledge of gene mutations and interactions in this species.AbstractThe world buffalo population is about 168 million, and it is still growing, in India, China, Brazil, and Italy. In these countries, buffalo genetic breeding programs have been performed for many decades. The occurrence of congenital malformations has caused a slowing of the genetic progress and economic loss for the breeders, due to the death of animals, or damage to their reproductive ability or failing of milk production. Moreover, they cause animal welfare reduction because they can imply foetal dystocia and because the affected animals have a reduced fitness with little chances of survival. This review depicts, in the river buffalo (Bubalus bubalis) world population, the present status of the congenital malformations, due to genetic causes, to identify their frequency and distribution in order to develop genetic breeding plans able to improve the productive and reproductive performance, and avoid the spreading of detrimental gene variants. Congenital malformations most frequently reported in literature or signaled by breeders to the Department of Veterinary Medicine and Animal Production of the University Federico II (Naples, Italy) in river buffalo are: musculoskeletal defects (transverse hemimelia, arthrogryposis, umbilical hernia) and disorders of sexual development. In conclusion this review put in evidence that river buffalo have a great variety of malformations due to genetic causes, and TH and omphalocele are the most frequent and that several cases are still not reported, leading to an underestimation of the real weight of genetic diseases in this species.

Dicephaly is a peculiar type of conjoined twins, which is observed in cattle and other vertebrates. The analysis demonstrates the course and division of arteries of the cranium of a one-day-old two-headed conjoined calf. In comparison with the normal pattern of the bovine cranial vasculature, the arteries of the head of the conjoined animal were considerably modified. The absence of the arteries found in anatomically normal cattle was compensated by very strong, modified linguofacial trunks located at the place where the animals' heads were conjoined. Brain base arteries, head vascularity, ruminantConjoined twins, resulting from a malformation of monozygotic twins, have been known at least since 6500 BC (Mellaart 1962). This condition is caused by an incomplete division of the embryo during the embryogenesis (Wagner et al. 2013).Dicephaly (dicephalus; two-headed monster) is a peculiar type of conjoined twins observed in cattle (Cornillie et al. 2006;Čítek et al. 2009). The case of a two-headed bull shark described by Wagner et al. (2013) proves that this malformation has a universal character in vertebrates.In The aim of this study was to describe the arterial vascularisation in a case of conjoined twin cattle, including the arteries of the encephalic base, and to compare this pattern with the anatomically normal head vascularisation in the same species. Materials and MethodsThe research was conducted on a one-day-old, two-headed conjoined still-born bull calf with five limbs, born from a Polish Red-and-White cow of the Bos taurus species. A Caesarean section was carried out during calving. The investigation was conducted on a corrosion preparation of the vessels on a bone scaffold. For this purpose the arteries of the animal under investigation were filled with acetone-dissolved stained vinyl superchloride. The injection mass was infused through the heart into the brachiocephalic trunk by means of an air-cushioned syringe at a pressure of 60-80 kPa. After about 40 days the mass had hardened and the heads were enzymatically macerated (Persil ® -Henkel, Düsseldorf, Germany) at a temperature of 38 °C. The resulting corrosion preparations were used to analyse the course, division and connections of arteries in relation to the bone scaffold of the cranium (skeletotopia).The anatomical nomenclature used conformed to an illustrated elaboration on the anatomical nomenclature (Simoens 1978(Simoens -1979. ResultsThe heads were conjoined in the atlanto-occipital region. The vertebrae of the cervical, thoracic, lumbar, sacral and caudal spine were present as a single set. The investigation
