Prepared by: Anadolu Birlik Domestic and International Sacrificial Animal Services Inc.Category: Livestock / Sacrificial Animal GuideSubject: Age Determination in Cattle Based on Tooth StructureUpdate: August 11, 2026
One of the most frequently asked questions when buying or choosing a sacrificial animal is its actual age. Especially in animals where sufficient information about the date of birth is not available, examining the tooth structure is one of the most common methods for getting an approximate idea of its age.
In cattle and buffaloes, the incisor teeth in the front part of the lower jaw are examined first. Unlike humans, cattle do not have incisor teeth in the front part of the upper jaw; there is a hard tooth cushion there. In age assessment, the change of deciduous and permanent incisor teeth in the lower jaw, the time of eruption, and wear on the teeth in later years are taken into account.
However, there is an important point:
Age determination from teeth is an approximate assessment. Birth and farm records should be used as the basis for the animal's exact age.
Republic of Turkey The Ministry of Agriculture and Forestry also states that if records are available, properly kept farm records provide accurate results; however, if records are not available, tooth development is an important method of age determination.
Which Teeth Are Examined in Cattle?When determining age in cattle and buffaloes, the eight incisors in the lower jaw are particularly evaluated.
These eight teeth can be considered in four pairs:
Central incisorsFirst central/lateral incisorsSecond central/lateral incisorsAxial incisorsWhen the animal is young, these teeth are deciduous teeth. As the animal ages, the deciduous teeth fall out and are replaced by larger, wider, and more durable permanent teeth.
In cattle, all eight incisors generally become permanent by approximately 4.5–5 years of age. After this point, age determination focuses more on wear and shape changes rather than the number of teeth.
Age Determination Chart for Cattle Based on Teeth: Approximate Age Changes in Teeth General Assessment 0–1.5 years Primary incisors Permanent incisors have not yet erupted 1.5–2 years First permanent incisors begin to erupt Two central permanent teeth become prominent Around 2 years First pair of permanent incisors fully developed “Cap” appearance begins to form 2.5–3 years Second pair of permanent teeth erupt 4 permanent incisors are visible 3.5–4 years Third pair of permanent teeth erupt 6 permanent incisors are visible 4.5–5 years Corner incisors also become permanent 8 permanent incisors are present 6 years and older Wear and spacing begin Age is estimated more based on tooth wear Advanced age Significant wear, shortening, spacing, and tooth loss Precise age determination becomes difficultThese age ranges are approximate values. Breed, nutrition, environment, care, and individual developmental differences can affect the timing of tooth eruption and wear.
What are the Teeth of a 1-Year-Old Cattle Like?Around 1 year of age, the front incisors of cattle are predominantly baby teeth.
Baby teeth are:Smaller,Whiter,Thinner,More delicate in appearance than permanent teeth.
The first permanent incisors are expected to start erupting around 1.5 years of age in cattle. Therefore, the presence of only baby incisors is an important sign that the animal is still young.
What are the Teeth of a 2-Year-Old Cattle Like?Around 1.5–2 years of age, the first pair of incisors in the exact center of the lower jaw begin to replace the baby teeth.
These teeth are:
Larger,Wider,Stronger,More prominent
Compared to baby teeth.
The first permanent incisors are expected to be fully developed around 2 years of age.
The condition commonly referred to as "shedding the cap" is particularly related to the eruption of these two front permanent teeth.
What Does "Shedding the Cap" Mean?In Türkiye, the expression "shedding the cap," frequently used when discussing the age of cattle, refers to the shedding of the two central deciduous incisors at the front of the lower jaw, replaced by two permanent incisors.
The Ministry of Agriculture and Forestry states that the presence of two fully developed permanent incisors at the front of the lower jaw of a cow or buffalo can be used as an indicator that the animal has reached two years of age.
However, there is a very important distinction here:
The shedding of the cap is not the same as knowing the animal's exact date of birth.
Tooth development provides a strong estimate of age; however, ear tag and registration information are more reliable for official age information.
How Many Permanent Teeth Are There at 2.5–3 Years Old?
The second pair of permanent incisors begins to erupt around 2.5 years of age and can be fully developed around 3 years of age.
At this stage, the animal's lower jaw can be expected to have:
4 permanent incisors + 4 deciduous incisors
This appearance is consistent with a cattle of approximately 3 years old.
How do teeth change at 3.5–4 years old?The eruption of the third pair of permanent incisors begins around 3.5 years of age.
Around 4 years of age:
6 permanent incisors + 2 baby incisors
may appear.
During this period, the permanent teeth in the animal's mouth have become more prominent, wider, and stronger.
Teeth of Cattle at 4.5–5 Years OldAround 4.5 years of age, the last pair of incisors also begin to change.
Around 5 years of age, the cattle will have:
All 8 incisors become permanent teeth.
This stage can be considered "complete permanent incisor structure" in cattle. Mississippi State University Extension also states that in cattle, the eight deciduous incisors are replaced by permanent incisors, and the appearance of these teeth changes as they age.
How to Determine the Age of a Cattle After 5 Years?After around five years of age, simply asking "how many permanent teeth are there?" is not sufficient for age determination.
Because all eight incisors are now permanent.
After this stage:
Tooth wear,Shortening of tooth length,Flattening of the upper surface of teeth,Increased gaps between teeth,Rounding of teeth,Prominence of tooth roots,Broken or fallen teeth are examined.
Around the age of 6, wear on permanent incisors begins to become noticeable. As age progresses, the upper parts of the teeth become more rounded and worn; gaps may form between the teeth.
How to Evaluate the "Mouth" of Cattle Aged 6 and Over?In livestock farming, various expressions can be used depending on the condition of the teeth in later years.
For example:
Healthy and not short teethIf the teeth are still strong, prominent, and long enough, the animal's mouth structure may not show many signs of advanced age.
Worn teethThe upper surfaces of the teeth begin to flatten and lose their sharpness.
Spaced teethGaps may form between the teeth as age progresses.
Broken or missing teethTooth loss can occur in older animals.
However, none of these findings alone indicate a definitive age. Diet, grazing, feed composition, breed, and individual differences can affect tooth wear.
Why is Age Determination from Teeth Not Accurate in Cattle?Age determination from teeth is quite useful, but it does not replace the date of birth.
Two animals of the same age may not have the same tooth development or wear.
The reasons for this include:
Breed differences,Genetic characteristics,Differential diet,Time spent in pasture,Composition of feed,Care conditions,Individual developmental differences.
Mississippi State University Extension emphasizes that age determination from teeth is useful when records are unavailable, but it is important to maintain birth records when the actual age is known.
Therefore, the most accurate approach is:
A multi-faceted assessment including:
Record + ear tag information + dental examination + general development of the animal.
How to Check the Age of a Sacrificial Cattle from Teeth?
This issue is important not only from the perspective of animal husbandry, but also from the perspective of the sacrifice ritual.
In Islamic law, cattle and buffalo must have completed two lunar years to be sacrificed.
The High Council of Religious Affairs of the Presidency of Religious Affairs explicitly states that cattle that have not reached two years of age but have "shed their teeth" cannot be sacrificed. However, if it is known with certainty that the animal has reached two lunar years of age, but its teeth have not yet shed, this does not prevent it from being sacrificed.
Therefore:
Shedding teeth = an important indicator of age.
However:
Shedding teeth = not an absolute document that replaces the two-lunar-year age requirement.
In animals whose birth date is not known with certainty, shedding teeth can be accepted as a practical measure in determining the age of the animal for sacrifice.
Is it correct to only look at teeth when buying a sacrificial animal?No.
When buying a sacrificial animal, in addition to age, the health and general condition of the animal should also be evaluated.
Republic of Turkey The Ministry of Agriculture and Forestry's guide to selecting sacrificial animals recommends paying attention to the following: ensuring the animals are tagged and registered; not being too thin, pregnant, or having recently given birth; having a lively general appearance; not exhibiting symptoms such as fever, excessive salivation, or eye and nasal discharge; and not having wounds, swelling, or edema.
Therefore, the following check sequence is quite useful when selecting a sacrificial animal:
1. Check the ear tag number.
2. Check the animal's registration information.
3. Check the age information.
4. Examine the incisors in the lower jaw.
5. Evaluate the animal's general health and development.
6. Check for any defects that would make it suitable for sacrifice.
Can the age of a large animal be determined from its ear tag number? Yes.
It is stated that through the TARIMCEBİMDE application developed by the Ministry of Agriculture and Forestry of the Republic of Turkey, registered information such as the animal's type, breed, gender, and age can be accessed using the ear tag number. The Ministry's information dated 2026 also states that animal registration and age information can be checked via TÜRKVET or TARIMCEBİMDE.
Therefore, when purchasing a large animal, especially one with a high price, it is important to check official records as much as possible instead of relying solely on the seller's verbal statement.
Practical Memorization for Age Determination in CattleWhen looking at the lower jaw of a large animal, you can think of it this way:
Milk teeth → Young animal
2 permanent incisors → approximately 2 years old
4 permanent incisors → approximately 3 years old
6 permanent incisors → approximately 4 years old
8 permanent incisors → approximately 5 years old
After 5-6 years → tooth wear is assessed
This table is for approximate age estimation. Records are prioritized for the animal's actual age.
Is Age Determination the Same for Cattle and Buffalo?The general principle for age determination in cattle and buffalo is similar: the transition of the incisors in the lower jaw from milk teeth to permanent teeth and the subsequent wear of the teeth are evaluated.
In Türkiye, for the age criteria for sacrificial animals, cattle and buffalo must have completed two lunar years.
However, since the animal's species, breed, and individual development can cause differences in the timing of tooth replacement, the exact date of birth should not be determined solely from a general chart.
Age Determination in Cattle from Teeth: Top 5 Key Facts1. Age determination is based on the incisors in the lower jaw.
2. Cattle do not have incisors in the upper front jaw; they have a dental cushion.
3. The first two permanent incisors become prominent around 2 years of age.
4. All eight incisors become permanent around 5 years of age.
5. After five or six years, age estimation relies more on tooth wear, and the margin of error increases.
Conclusion: What is the Most Reliable Way to Determine the Age of a Cattle?In cattle, the tooth structure provides important information about age, especially in animals whose date of birth is unknown. The eruption of the first permanent incisors, the replacement of subsequent pairs, and finally the permanent formation of all eight incisors help to approximately determine the age.
However, the evaluation based on teeth should be considered as "oral age"; The actual chronological age of the animal may not always match the actual age.
Therefore, the most accurate method when purchasing sacrificial cattle is:
EAR TAG REGISTRATION → OFFICIAL AGE INFORMATION → DENTAL CHECK → GENERAL HEALTH AND DEVELOPMENT
This is the correct procedure.
Especially for sacrificial animals, it is a fundamental requirement that cattle and buffaloes have reached two lunar years of age. While "having shed their teeth" is an important practical indicator of age in animals whose birth date is unknown, it should not be understood as replacing the two-year requirement.
