Comprehensive Cattle Disease Diagnosis and Management Quiz

The correct answer includes a list of differentials for the described lesion, which are Nasal erosions, nasal ulceration, Bovine papular stomatitis, BVDV, FMD, and Vesicular stomatitis. The incorrect answers provided do not match the specific differentials mentioned in the correct answer.

Wooden tongue in cows is caused by Actinobacillus ligneresi, leading to gritty, granulomatous abscesses on the tongue. It is contracted by cows through plant awns or stems causing mucosal damage.

Oral necrobacillosis is caused by Fusobacterium necrophorum and typically affects infants aged 2 weeks to 3 months. The disease is characterized by mucosal injury leading to an opportunistic invasion.

The handler is showing an oesophageal obstruction, which can be remedied by sedating the animal, performing deep internal palpation to remove the obstruction, massaging externally, passing a tube if the obstruction is too far in, and flushing with the head down to prevent aspiration.

Dehydration levels in animals can be determined based on clinical signs, not just on estimated percentage. Possible differentials for the calf include E. coli, rotavirus, salmonella, coronavirus, and coccidiosis based on common causes of calf diarrhea.

The correct answer includes common pathogens like Coronavirus, E. coli, Rotavirus, and Cryptosporidia which are often tested for in diagnostic kits. The incorrect answers do not align with the pathogens typically detected by this type of testing kit.

Bacterial meningitis and viral meningitis are common neurological diseases that can affect cattle. Rabies, foot-and-mouth disease, and mad cow disease are also serious diseases that can affect cattle, but they are not specifically neurological in nature.

The correct answer describes a cow with abdominal distension and provides differential diagnoses related to the gastrointestinal tract. The incorrect answers suggest conditions unrelated to the presented symptoms, such as respiratory issues, joint problems, and neurological disorders.

The 'bloat line' seen in the picture is characterized by congestion at one end and ischemia at the opposite end, resulting in a visible line. This phenomenon is typically caused by frothy/gas bloat and post-mortem changes due to bloating. Other options like normal tissue coloration variations, excessive sunlight exposure, and dehydration do not explain the specific findings associated with the 'bloat line'.

The correct answer describes a condition where hardware is present in the reticulum of the animal, potentially leading to Traumatic Reticuloperitonitis. This condition should not be confused with the incorrect answers provided, which involve different pathologies and anatomical locations.

The correct answer includes signs of abdominal pain and potential differential diagnoses related to abdominal issues that may be causing these symptoms in the cow.

The correct answer is left displacement of abomasum, which is characterized by a ping sound upon percussion in the left abdomen. Right sided congestive heart failure, pulmonary hypertension, and acute pancreatitis do not typically present with abnormal auscultation findings in the abdomen.

Auscultation of the abdomen in cattle can help identify various gastrointestinal issues such as abomasal displacement or caecal dilation. Pneumonia, intestinal obstruction, and heart murmurs are not typically identified through abdominal auscultation in cattle.

Segmental jejunal aplasia presents in very young individuals with specific clinical signs. The condition is different from appendicitis, colonic diverticulitis, and Meckel's diverticulum, which have their own distinct features and age groups.

Intussusception is a medical condition where one segment of the intestine telescopes into another segment causing obstruction. It is common in young children under 12 months old and presents with the clinical signs of absence of faeces, abdominal distension/pain, and malaena.

A strangulating hair ring around the penis can lead to a risk of amputation or ischaemia due to reduced blood flow. It is a serious medical issue that requires immediate attention.

A persistent frenulum is a condition in which a small piece of tissue under the tongue (or in other parts of the body) does not break or rupture on its own as it normally would. It is usually heritable and can be easily treated by surgically snipping the frenulum.

The correct answer is prematrue spiral deviation of the penis with the involvement of the dorsal apical ligament. It is a heritable condition and cannot be seen without observing serving multiple times.

Ulcerative posthitis is inflammation of the prepuce in bulls caused by Clostridium renale bacteria.

The correct answer describes a specific lesion in a bull's prepuce and provides appropriate treatment and associated risks. The incorrect answers are unrelated conditions in different animals with incorrect treatment and associated risks.

The correct answer is prepucial eversion where there is no pathology involved unless the bull is unable to retract the sheath. The incorrect answers provided describe different medical conditions which are not applicable in this scenario.

The correct answer is prepucial prolapse which is a condition in bulls. It is more common in Bos indicus breeds and bulls with pendulous sheaths. The treatment involves compression with replacement in sheath, local and systemic antibiotics, belly sling, and sexual rest.

Varicocoele and vaginocoele are common causes of scrotal masses that should be considered in the differential diagnosis. Inguinal hernia, hydrocele, and epididymitis are other conditions that can present with similar symptoms but have different etiologies.

The correct answer describes an inguinal hernia, which is characterized by swelling at the head of the epididymis. Appendicitis, kidney stones, pneumonia, and testicular torsion have different symptoms and should not be confused with an inguinal hernia.
