Management is of 2
types:
- According to physiological stage.
- Feeding management, breeding management, health management and housing and sanitation
MANAGEMENT OF CALVES
- To get an alive and healthy calf.
- To get optimum growth rate.
- To keep the calf healthy.
- To reduce the calf mortality.
It is fact that
nearly 50 % calves die up to 2 months of age. This is the big loss
not only for the farmers but it also weakens the national economy as
we have to face the challenge of animal protein deficiency for our
masses.
FACTORS LEADING TO HIGH
CALF MORTALITY ARE:
- Delayed colostrum feeding.
- Naval ill.
- Parasitism.
- Pica.
- Theleriasis
- Certain diseases such as white scovers, dympany and some mineral deficiencies.
- Hair boll.
- Under feeding of calves.
- DELAYED COLOSTRUM FEEDING:
There is one tradition that colostrum is fed to calves after dam’s
placenta expulsion. Recommendation is to feed the colostrum within 1
hour after calving because the immunoglobulin absorption decrease
with the passage of time after calving and it is almost zero at 24
hrs. Immunoglobulin is the only weapon to develop immunity.
- NAVAL ILL:
There is one tradition that naval cord is not cut with an idea that
it will dry and slough off. Butt so many times before drying it
breaks from any spot; the point from where it breaks is the best
place for the entry of bacteria. These bacteria
multiply that lead to the swelling of cord known as omphlitis. Due to
high severity, this leads to septicemia and then death. Simple
solution is to cut the naval cord.
- PARASITISM:
Due to high parasitism, up to 50 % drop in growth rate occurs. This
leads to late maturity. Parasites are of 2 types:
- INTERNAL PARASITES
These include nematodes, trematodes, custods etc. The high EPG (egg
per gram) will lead to weakness, emaciation and finally death.
SOLUTION
- Properly wash the teats of dam.
- If the calf is licking, then use muzzle.
Licking may be due to:
- Habit
- Deficiency of phosphorus (in this case use phosphorus supplement)
b) EXTERNAL PARASITES
These include
lice, ticks, mites, flies etc. These are actually the blood suckers.
- PICA:
Eating of undesirable things due to phosphorus deficiency is known as
pica. In this case, use grains, if grains are not available
then use DCP, if DCP is also not available then use SUPER
JUICE. SSP can also be used.
PREPARATION OF
SUPER JUICE
Take 1 kg fertilizer (DCP or SSP). Add it in 5 liter water and mix it
thoroughly. Keep it for 12 hrs , and then collect the super juice
without disturbing the settled matter. Give 25-50 ml per day
depending upon the weight of calf.
The following
management practices are important to minimize the mortality rates in
calves:
- Feed colostrum within 1 hour.
- Injection butalex at the age of 10 days in case of Theleriasis in cross-bred calves.
SYMPTOMS of
THELERIASIS:
106 F
temperature, swelling under ears, bulging of eyes.
3) NAVAL CORD
CARE.
4) Do Deworming at
the age of 1 month and repeat it after every 3 months. Always use new
salts of dewormer in each time. 3 salts of dewormer are common in
Pakistan:
* ALBENDAZOL
* OXFENDAZOL
* LEVAMIZOL
- Prevent the problem of white scovers by washing the teats of dam prior to calf feeding and use clean utensils for feeding of calves. We can use TRIMODIN BOLUS @ 1 bolus per 40 kg body weight.
- Feed the calf according to recommendations especially do measures to prevent the problem of mineral deficiency.

Early
weaning is the best at 8th week of age. We can wean the
calf earlier by introducing the calf starter in the feed regime of
the calf @ 1 % body weight.
