What causes Curly calf Syndrome?

Curly Calf Syndrome is a genetic defect, which researchers believe is caused by a simple recessive gene. It can cause calves to be stillborn with twisted spines. Early research information traces the syndrome back to a popular Angus bull.

What is curly calf?

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 breed of cattle have curly hair?

…the native home of the Galloway breed is the ancient region of Galloway in southwestern Scotland, it probably had a common origin with the Angus. The Galloway is distinguished by its coat of curly black hair.

What is fawn calf syndrome?

Summary. Congenital contractural arachnodactyly (CA), also known as “fawn calf” syndrome (FCS), is a heritable disease of newborn Angus and Angus-derived cattle caused by an error in the DNA genetic code transmitted from parents to their progeny.

Why would a calf be born without hair?

Hypotrichosis (Hairlessness) Calves are often born with no hair but will grow a short curly coat of hair with age. Affected individuals are prone to environmental stress (cold and wet) and skin infections are more prevalent. A recessive gene causes hairlessness.

What is a water headed calf?

Calves often have trouble with joint range of motion and do not lay down in a normal calf position. Calves are reported as more slender and taller than their normal siblings. Neuropathic Hydrocephalus (Water Head). This lethal mutation causes an excess of water to form in the cranium.

What is Shaker calf syndrome?

Shaker calf syndrome is a neurodegenerative disorder that is seen in Hereford calves. Affected animals show a marked tremor within hours of birth, difficulty in rising, a stiff gait, and loss of voice; signs progress to spastic paraplegia.

What is th carrier in cattle?

TH. Tibial Hemimelia (TH) is a lethal genetic condition inherited when affected animals inherit two copies of a recessive gene. Calves are born with severe deformities including twisted rear legs with fused joints, large abdominal hernias and/or skull deformities.

How long should you wait to pull a calf?

The rule of thumb is to wait one hour in cows and 1.5 hours with heifers once they show strong uterine contractions with no progress. Exceptions to this rule are when cows or heifers are uneasy, bawling, or nesting for an extraordinary period of time.

How do you treat a shaker calf?

There is no treatment.

Why are my calves so wobbly?

Calves may stagger or sway as they walk; this often reflects weakness, low blood sugar concentrations, and/or alteration of the acid-base balance of their bodily fluids. Calves become too weak to stand.

What does DS mean in cattle?

Digital Subluxation
DS. 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 does PHA mean in cattle?

Pulmonary hypoplasia with anasarca (PHA) is a lethal genetic defect that leads to abortion or the birth of a dead calf. Associated dystocia can also lead to death of the cow. PHA is characterized by incomplete development of the lungs and severe subcutaneous fluid accumulation.

How many Gardiners have raised stillborn calves with no precision?

That was a potential diagnosis provided by renowned Kansas State University geneticist Horst Leipold, when the Gardiners brought a stillborn calf to him that had a bent and twisted spine. Since then, the Gardiners have bred and raised about 27,000 calves. Eleven were stillborn and anatomically abnormal; six had no Precision in their pedigrees.

How common is the precision 1680 gene in Angus?

All told, 761 Angus sires were tested; 60 bulls turned up carriers, all directly related to Precision 1680 and 9J9. That 8% says nothing about the actual gene frequency within the breed. Anecdotally, however, it suggests the gene isn’t nearly as pervasive as some may have feared.

Is precision 1680 a good sire?

Precision 1680 was one of the first Angus sires to bend the genetic curve, providing low birth weight but superior weaning and yearling growth. Born in 1990 and deceased for a decade, his progeny continue to be favorites of seedstock and commercial producers.

How many descendants does a precision 1680 have?

According to Precision 1680’s performance record from the American Angus Association (AAA), nearly 10,000 direct sons and daughters are part of the breed’s genetic evaluation. Multiply that by a likely factor of 30 or 40 and you start to grasp the number of descendents this bull has spawned within the breed.
