CATDOLL : CATDOLL: Detailed explanation of sow farrowing rate and its calculation method

Sow farrowing rate is one of the important indicators in the pig farming industry. It is used to measure the fertility of sows in the pig farm and the breeding efficiency. The method of calculating sow farrowing rate is usually based on statistical analysis of the reproductive data of the pig herd to obtain accurate results.

1. Definition of sow farrowing rate

Sow farrowing rate refers to the proportion of sows that successfully farrow within a specific period of time. The common statistical period is one year or one production cycle (from breeding to fattening) to understand the fertility status of sows.

2. Calculation method of sow farrowing rate

Typically, sow farrowing rate is calculated by dividing the number of successful farrowings per sow by the total number of breedings of that sow, and then multiplying the result by 100%.

The calculation formula is as follows:

Sow farrowing rate = (number of successful farrowings ÷ total number of breedings) × 100%

3. Derivation Examples

Let’s take an example to illustrate how to calculate the sow farrowing rate.

Assume that a pig farm carries out 1,000 matings in a year, and 800 sows successfully give birth. According to the calculation formula:

Sow farrowing rate = (800 ÷ 1000) × 100% = 80%

The sow farrowing rate on this farm is 80%.

4. Methods to improve sow farrowing rate

Improving the sow farrowing rate helps improve the breeding efficiency of the pig farm. The following are some commonly used methods to improve the sow farrowing rate:

• Reasonable feeding and management: regularly give sows healthy feed to ensure their balanced nutritional intake, and at the same time pay attention to the living environment and sanitary conditions of the sows to prevent the occurrence of diseases.
• Reasonable breeding management: choose the appropriate breeding time and breeding method to ensure that the sows are in the best conditions for breeding.
• High-quality breeding pigs: Selecting breeding pigs from breeds and bloodlines with good fertility can improve the fertility of future generations.
• Scientific breeding management: Develop a scientific fattening plan based on the reproductive characteristics of sows to improve the conception rate and survival rate of sows.

Through reasonable feeding management, mating management and breeding management, the sow farrowing rate can be effectively improved, thereby improving the production capacity and economic benefits of the pig farm.

Thank you for your patience in reading this article. I believe that through the introduction of this article, you have a clearer understanding of the definition and calculation method of sow farrowing rate. Reasonable improvement of sow farrowing rate is of great significance to the development of pig farming.
