Young calves develop 20 temporary teeth termed deciduous, milk or baby teeth. Around the age of 14 to 18 months, these teeth begin to be replaced by the permanent teeth. By the time they are 5 years old cattle will have grown 32 permanent teeth. The easiest teeth to examine to determine age are the incisors.
Can you tell a cows age by its teeth?
Eruption times and wear of the teeth are the major factors used to estimate bovine age. The definition of eruption is the emergence, penetration or piercing of the tooth or teeth through the gingiva (the gum line). An animal at 14 months of age would have a full set of deciduous incisors.
How many teeth does a 3 year old cow have?

What is the maximum age of cow?
The normal lifespan of a cow/bull is about 15 years. But for a farmer, his cow is unproductive once it is eight or nine years old and would have calved five-six times. By then, its milk yield would have dropped to levels where maintenance becomes uneconomical.

What is the age of eruption of teeth in cattle?
The range in age at teeth eruption varies enormously from beast to beast due to individuality, breed, nutrition and climatic influences. Cattle, such as British-bred cattle, that exhibit early sexual maturity (puberty) experience teeth eruption at younger ages than late maturing cattle, such as Brahman cross cattle.
How can you tell how old a cow is by its teeth?
Using Teeth to Age Cattle. They have straightened and the inside corners are in line. Animals with eruption of one or more central incisors are considered to be 18 to 24 months of age. When one or both middle (I2) incisors erupted the animal is considered to be 24 to 30 months of age (Figure 7).
