Hydrocephalus occurs mainly due to three reasons, as excessive production of CSF, defective absorption of CSF,and interference in the passage of CSF.
What causes deformities in calves?
Occasionally pregnant cattle (particularly beef cows or heifers), overwintered on silage give birth to deformed calves. The calves are small due to shortening of the long bones in the legs, which gives them a characteristic short, bow-legged, appearance. They may also have dished faces and domed heads.
What is Curly calf syndrome?
Arthrogryposis Multiplex (AM), commonly known as Curly Calf syndrome, is a lethal genetic defect that was recently confirmed within the Angus breed. Other breeds with Angus in their pedigree may also be affected. An AM-affected calf is born dead, appears thin, and most notably, has a bent or twisted spine (Figure 1).
What is dummy calf syndrome?
We refer to this behavior as neonatal maladjustment syndrome, or “dummy calf” / “weak calf” syndrome. These calves are weak, aimlessly wander, refuse to suck, and fail to find the udder. Some possible causes or factors contributing to weak newborn calves are: Dystocia (difficult calving)
What is Hydrancephaly?
Definition. Hydranencephaly is a rare condition in which the brain’s cerebral hemispheres are absent and replaced by sacs filled with cerebrospinal fluid. An infant with hydranencephaly may appear normal at birth.
What is Neuropathic Hydrocephalus?
The bones of the skull are malformed and appear as loosely organized bony plates that fall apart when the cavity is opened. The cranial cavity is filled with fluid and no recognizable brain tissue is evident. The spinal canal is also dilated and no observable spinal tissue is found.
What might shunt function lead to in a horse?
Portosystemic shunts are conditions in which blood vessels bypass all or part of the liver, causing toxins normally removed by the liver to remain in the blood. This lack of processing causes increased ammonia levels in the blood and nervous system signs.
How common is Schistosomus Reflexus?
Introduction Schistosoma reflexus is a rare type of fetal monstrosity, primarily observed in cattle and occasionally in sheep, goat and other species having incidence rate of 0.01-1.3% out of total bovine dystocia occurring worldwide.
Can a cow survive a prolapsed uterus?
The prognosis is generally favorable if the cow survives having the uterus replaced, and most cows survive into the long term. Normally, if a prolapsed uterus is placed back into the animal correctly there are no further complications.
How long does it take for cow to pass afterbirth?
Most cows will pass the afterbirth (placenta, cleansing or calf bed) within 6 hours of calving. Some cows take up to 24 hours. If the placenta is retained longer than this, the condition is classified as retained placenta or retained fetal membranes (RFM).
What are the symptoms of liver disease in horses?
Liver disease and liver failure in Horses: Symptoms, causes & Treatment
- Jaundice: May be visible in the horse’s mouth, nostrils or eye areas.
- Loss of condition.
- Abdominal pain.
- Blood clotting may be reduced, leading to excessive bleeding or increased oedemas.
- Discoloured urine.
- Head pressing.
Can a horse recover from liver damage?
Horses affected by this serum hepatitis exhibit acute liver failure signs such as blindness, stumbling, jaundiced mucus membranes and head pressing. The good news is that if caught early and given appropriate supportive care, most affected horses recover with no lasting side-effects.
Is milk thistle good for horses?
Milk thistle for horses, the powdered seed is rich in antioxidants and can be used to promote a healthy equine liver. Milk thistle will help to support the body’s natural regeneration of new liver cell growth and, as a result, give nutritional support for healthy hooves, healthy skin and the whole immune system.
What is TH and PHA in cattle?
When Dr. Hannon was finding TH calves, he also discovered some Shorthorn calves thought to have TH actually had something different — PHA (pulmonary hypoplasia with anasarca). Translated, that means little, poorly formed lungs (pulmonary hypoplasia) and lots of excess, retained fluid (anasarca).
What is a DS carrier in cattle?
Digital Subluxation (DS) is not a lethal condition from a genetic inheritance standpoint. Animals known as homozygotes are cattle that carry two copies of the undesirable gene. Homozygotes of DS, referred to as “DSH” in the registry. Most cattle that are DSH will show some outward signs of the genetic condition.
What is dwarfism in cattle?
Bulldog dwarfism is a lethal genetic defect of Dexter cattle. Affected fetuses have severe disproportionate dwarfism, a short vertebral column, a large head, and are naturally aborted around seven months of gestation. The two known mutations are specific to Dexter cattle and may be present in Dexter crossbreds.
What is it called when your head is bigger than your body?
Macrocephaly refers to an overly large head. It’s often a symptom of complications or conditions in the brain. There’s a standard used to define macrocephaly: The circumference of a person’s head is more than two standard deviations above average for their age.
How common is Megalencephaly?
Megalencephaly is three to four time more common in males than females, reports The Gale Encyclopedia of Neurological Disorders. It affects between 10 and 30 percent of patients with macrocephaly. Asymptomatic cases may not be reported, so the incidence is unknown.
What does Schizencephaly mean?
Schizencephaly is an extremely rare developmental birth defect characterized by abnormal slits, or clefts, in the cerebral hemispheres of the brain.
How do you know if a calf has scours?
Common signs of calf scours include:
Dehydration that can result in a sunken-eyed appearance. Ribs, hips, and shoulders may become more prominent as dehydration becomes more severe. Depression and a lost desire to nurse. Weakness resulting in staggering or an inability to stand.
How do you tell if a cow has a dead calf inside?
Here one must be very confident the calf truly is dead, and that can be difficult. The finger in the rectum for sphincter tone is one way but if a cow has been straining, one can be fooled. The only other way is to reach down and feel the umbilical vessels for signs of a pulse.
How long does it take a calf to get up after birth?
Calves should stand and nurse within 2 hours of birth if everything is normal and weather is not severe. For maximum antibody exposure from the colostrum, calves need to nurse within four hours of birth.
What are signs of kidney failure in a horse?
The most common signs linked to chronic kidney disease are weight loss, ventral edema (usually located between their front legs, or a swollen sheath), increased urination (polyuria), increased water intake (polydipsia), or generally just not doing right.
