2. Vices
Vices are abnormal or bad habits shown by the animals.
In the following slides we discuss
1. Eye rolling
2. Tongue rolling
3. Licking and eating own hair, wool
4. Sucking and eating solid objects
5. Intersucking by calves
6. Intersucking or milk sucking by adult animals

3. 1. Eye rolling
The eyes are moved around in the orbit at a time when no
visible object is present.
Normally seen in calves confined in crates and stand
immobile for extended period.

4. 2. Tongue rolling
The tongue is extruded from the moth and moved by curling and
uncurling outside or inside the mouth with no solid material
present.
This condition occurs in all ages and breeds but young adult cattle
and certain breeds such as Brown Swiss are exhibiting it most
frequently.
Factors responsible for these vices may be hereditary, continuous
confinement, feeding of low roughages.
Control method includes dietary inclusion of salt mixture, free
movement.

5. 3. Licking and eating own hair, wool
.
Many young calves housed in individual crates, early weaning
leads to licking those parts of their bodies which they can
reach, this results in ingestion of large quantities of hair wic
aggregates into hair balls or bezoars in the rumen.
This vice is more common in calves moved from individual pen
to group housing.

6. 4. Sucking and eating solid objects
Recently weaned calves will often suck and lick the walls,
bars of their pen.
This can be controlled by regular creosote paint of wood
surface. Feeding good quality concentrate and roughage
will minimize the incidence.

7. 5. Intersucking by calves
Calves separated from their mothers suck and lick at their
own bodies, at objects in their pens and at parts of the
bodies of other calves.
The commonly suck on the navel, prepuce, scrotum, udder
and ears of other animals.

8. 5. Intersucking or milk suckling by adult animals
This behavior involves a cow or bull sucking milk from the
udder of a cow.
Cattle suck milk from herd mates and choose the same
lactating animal.
This vice may lead to loss of milk yield and damage to teat.
Proper feeding management and herd supervision can
minimize such incidents.
