CATDOLL : Master the skills of sow age identification: rapid identification and scientific breeding

In the breeding industry, especially in sow breeding, understanding the age of sows is crucial for breeding efficiency and production planning. Accurately identifying the age of sows can not only help farmers carry out breeding management at a reasonable time, but also effectively control feeding costs and improve breeding results. This article will introduce in detail how to identify the age of sows, as well as related skills, to help farmers manage sows scientifically.

1. The importance of sow age

The age of a sow directly affects its reproductive capacity, health and production efficiency. Here is why it is important to know the age of the sow:

• Reproductive capacity : Young sows are generally more fertile, conceiving more frequently and producing healthy piglets.
• Health status : As they age, sows may suffer from more health problems. The disease resistance of older sows often decreases, affecting the overall breeding efficiency.
• Production efficiency : Knowing the optimal production age of sows can help reduce unnecessary costs and improve economic benefits.

2. The main method of identifying the age of sows

Understanding the age of sows can usually be identified in the following ways:

1. Check your teeth

The growth and wear of a sow's teeth is an effective basis for judging its age. The following are the characteristics of sows' teeth at different ages:

• Piglets (0-6 months) : The deciduous teeth are fully developed.
• First-time sows (6-12 months) : They begin to change their teeth, and the deciduous teeth are gradually replaced by permanent teeth.
• Adult sows (1-2 years old) : The main permanent teeth have already erupted and are less worn.
• Old pigs (over 3 years old) : Teeth are obviously worn and may be missing.

2. Observe body shape and hair

The body shape and hair condition of sows are often related to their age. Generally speaking:

• Young sows : They are usually smaller and stronger than older sows, with shiny fur.
• Older sows : are usually larger and their hair may become sparse or dull.

3. Evaluate production records

Farmers should judge the age of sows based on their reproductive records . For example, by recording the time of each mating and birth, the age of the sow can be reasonably estimated.

4. Check the reproductive organs

The reproductive organs of sows change as they age, especially after farrowing:

• Primiparous sows : The reproductive organs are firm and have good elasticity.
• Older sows : The reproductive organs may become loose and atrophied.

3. Other auxiliary tools and techniques

In addition to the above methods, farmers can also use modern technology to improve the accuracy of sow age determination:

• Electronic ear tags : Each sow is equipped with an electronic ear tag to record its date of birth and reproduction information.
• Genetic testing : Genetic analysis can provide a more accurate understanding of the genetic characteristics and age of sows.
• Regular check-ups with veterinarians : Invite veterinarians to conduct health checks on sows regularly, using their expertise to determine the sows’ age and health status.

4. The relationship between sow age and breeding management

Understanding the age of sows is crucial for breeding management. Reasonable management can improve breeding efficiency. Here are some suggestions:

• Develop a scientific breeding plan : Develop corresponding breeding plans according to the different age groups of sows to improve the conception rate.
• Reasonable feeding and management : Young sows and old sows have different feed and nutritional requirements, and farmers should make adjustments according to their age.
• Update breeding pigs in time : As the number of aging sows gradually increases, farmers should evaluate them regularly and update breeding pigs in a timely manner to maintain good reproductive efficiency.

V. Conclusion

Knowing how to identify the age of sows is an important part of pig farming. By observing the sow's teeth, body shape, breeding records and reproductive organs, combined with modern scientific and technological means, farmers can effectively identify the age of sows. At the same time, reasonable management based on the age of sows can help improve production efficiency and economic benefits.
