CATDOLL : CATDOLL: Calculation method of monthly farrowing rate of sows and analysis of its influencing factors

Definition of monthly farrowing rate of sows

The monthly farrowing rate of sows refers to the ratio of the number of farrowings of sows in a pig farm or farmer in a specific month to the number of piglets born in that period of time. It is usually expressed as a percentage and can be used to evaluate the reproductive health level and production efficiency of sows.

Calculation method of monthly farrowing rate of sows

The formula for calculating the monthly farrowing rate of sows is as follows:

Farrowing rate = number of farrowing sows / number of pregnant sows × 100%

Among them, the number of farrowing sows is the number of sows that actually give birth in a certain month, and the number of pregnant sows is the number of sows that start to become pregnant in that month.

Factors affecting monthly farrowing rate of sows

The monthly farrowing rate of sows is affected by many factors, including but not limited to the following:

• Feeding and management: The feeding and management level of sows is directly related to their farrowing rate, such as reasonable feed nutrition and scientific feeding environment.
• Disease control: The occurrence of pig diseases will affect the reproductive capacity of sows. Reasonable immunization and prevention and control measures are crucial to improving the birth rate.
• Genetic factors: The genetic background of the sow determines its reproductive ability level. Breeding highly productive sows is also important for improving the farrowing rate.
• Environmental factors: The living environment of the sow has a certain impact on its farrowing rate, such as temperature, humidity, ventilation, etc.
• Breeding strategy: Reasonable breeding time and method can effectively increase the birthing rate and reduce empty pregnancy.

Summarize

The monthly farrowing rate of sows is one of the important indicators to measure the reproductive efficiency of sows. Understanding the calculation method and influencing factors will help pig farms or farmers improve the production efficiency of sows, control production costs, and gradually achieve sustainable development.

Thank you for reading this article. I believe that by understanding the calculation and influencing factors of the sow's monthly farrowing rate, you can better manage and improve the production efficiency of the pig farm and maximize economic benefits.
