- This is a simple method.
- It is popular in dairy farm.
- These registers have the records ranging from pregnancy period to the date of delivery and so on.

Major determining factors are as follows:
- General physical structure of a cattle.
- Shape of the cattle body.
Explanations:
- Small and fit ears means young age.

(3). By the shape and size of udder
- Small udder = Young age.
- Well shape medium udder = Adult.
- Bigger and loose shape = Old age.
(4). By hoofs
It is not a standard method of the age judging of a cattle.
- Small hoofs = Young age.
- Bright hoofs = Young age.
- Longer hoofs = Old age.
- Wider hoofs = Old age.
- Rough hoofs = Old age.
(5). By horns
We can predict the age of a cattle by counting the total rings which are present on the horn of the cattle.
Formula: First ring appears at the age of three years, after that one ring appears in every year.
Age of cattle in years = The nmber of rings on a cattle’s horns + 2
(6). By teeth
- It is a standard method of the age judging of cattle.
- Careful inspection of teeth is necessary.
Dental formula
There are two types of dental formula:
(a). For temporary teeth.
(b). For permanent teeth.
(a). Dental formula for temporary teeth
2 [ (Di × 0/4) × (De × 0/0) × (DP × 3/3) = 20]
Where,
Di = Deciduous incisors.
De = Deciduous canines.
DP = Deciduous premolars
(b). Dental formula for permanent teeth
2 [ (I × 0/4) × (C × 0/0) × (P × 3/3) × (M × 3/3) = 32]
I = Incisors.
C = Canines.
P = Premolars.
M = Molars.
Important points:
Pairs of temporary teeth
A 0 – 2 weeks old calf has 4 – 8 temporary incisors in lower jaw.
Six-month old calf has fully developed temporary teeth.
First pair: At the age of 10 months.
Second pair: At the age of 1 year and 3 months.
Third pair: At the age of 1 year and 6 months.
Fourth pair: At the age of 1 year and 9 months.
Pairs of permanent teeth
First pair: At the age of 2 years.
Second pair: At the age of 2.5 to 3 years.
Third pair: At the age of 3.5 to 4 years.
Fourth pair: At the age of 4.5 to 5 years.
