CATDOLL : Calculation method and influencing factors of sow farrowing rate

Calculation method of sow farrowing rate

The farrowing rate of sows refers to the proportion of piglets successfully produced by sows within a certain period of time, usually expressed as a percentage. It is not difficult to calculate the farrowing rate of sows. The following formula is generally used:

Sow farrowing rate = (number of sows farrowing successfully / total number of sows) × 100%

Factors affecting birth rate

The farrowing rate of sows is affected by many factors, including:

• Feeding and management: Reasonable feeding and management has a direct impact on the productivity of sows, including feed supply, production environment, disease control, etc.
• Genetic breed: Sows of excellent genetic breeds tend to have higher farrowing rates, and selecting high-yielding breeding pigs is an effective way to increase farrowing rates.
• Disease prevention and control: Regularly vaccinate sows and carry out disease prevention work to prevent the impact of diseases on production performance.
• Reproduction management: Scientific and reasonable reproduction management can effectively improve the sow's farrowing rate, including breeding time selection and breeding system.

The farrowing rate of sows is one of the important indicators to measure production efficiency. Correctly calculating the farrowing rate and improving the influencing factors in a targeted manner can help pig farmers improve production efficiency and optimize economic benefits.
