Why would a calf be born blind?

Calves that are born alive from a cow with low vitamin A levels may be blind from micropthalmia or constriction of optic nerve, have deformed bone development or weak uncoordinated muscles leading to inability to nurse.

What causes bad eyes in calves?

Pinkeye is most often caused by Moraxella Bovis (M bovis), a bacterial organism. Although this is the most common bacteria that can cause pinkeyes in cattle, there are also some other potential causes. These include infectious bovine rhinotracheitis virus (IBR), mycoplasma bovis, and Moraxella bovoculi.

What causes birth defects in calves?

Malnutrition, toxic factors, infectious disease, or extreme weather may be to blame for these congenital defects. When a pregnant cow consumes the lupine plant between days 40 to 60 of gestation, her calf may be born with crippled-calf (crooked-calf) disease, a crooked-leg condition.

What do you do with a blind cow?

We have had a few eyes removed and the cows do well and sometimes last for 4 or 5 years. We have also had an eye removed, but the cancer came back in the bone. If we have a cow we cannot sell, we usually let her calve if she is close and rob the calf if we loose one then shoot the cow.

How do you know if your calf is blind?

Blind cattle may be seen circling, knocking into objects and have no menace response (i.e. they won't blink when a hand is waved in front of their eye).

How do you treat night blindness in cattle?

In affected cattle, the recommended treatment regimen consists of parenteral injection of 440 IU/kg of vitamin A once daily for 3 to 4 days and then 6000 IU/kg every 50 to 60 days until the diet has been enriched.

What is blue eye in cattle?

Blue eye disease (BED) is the common name for a disease caused by a porcine rubulavirus (Paramyxoviridae; La Piedad Michoacan virus) that is characterized in nursing or growing pigs by central nervous system (CNS) signs and, frequently, by corneal opacities.

How do you treat bad eyes in cattle?

The best treatment for pinkeye is an injectable antibiotic. As of this writing, the approved products to treat pinkeye in beef cattle include long-acting tetracycline products (for example, LA-200®, Biomycin 200®, etc.) and tulathromycin (Draxxin®).

Why is my cows eye white?

The cornea may become inflamed and ulcerated; the eye may turn cloudy and have a white spot or bulge on it. In cattle, the problem may be mistaken for pinkeye, but pinkeye is generally a summer problem when face flies spread infection from animal to animal.

What is fawn calf syndrome?

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. Calves with CA are visibly abnormal at birth (Fig. 1) but are usually born alive.

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 a deformed calf called?

Ranchers referred to deformed calves as 'acorn calves' due to a belief that the ingestion of acorns by dams during gestation led to the condition.

What is silage eye?

Pink Eye is also called Infectious Bovine Keratorconjunctivits (IBK), Silage eye, or conjunctivitis and is one of the most common diseases of cattle. The disease has a world-wide distribution and is usually seen in epidemics when a chronically or subclinically infected animal enters a herd.

What causes vitamin A deficiency in cattle?

If cattle are grazing green grass they will get plenty of vitamin A. Deficiencies can be an issue at times when the grass isn't green such as winter or during drought. Drought can compound vitamin A deficiency because plants go dormant early in the year and it's a long time before animals eat green grass again.

How do you treat vitamin A deficiency in cattle?

Injectable vitamin A is a quick method of returning the cow's vitamin A status back to normal. 1.5 million IU of vitamin A are needed for an adult cow. If severely vitamin A deficient, monthly injections may be needed.
