CATDOLL : CATDOLL: Calculation method of monthly sow breeding rate and its influencing factors

The monthly sow breeding rate is one of the important indicators to measure the breeding management level of the farm. It reflects the proportion of sows successfully bred in a month. Correctly calculating the monthly sow breeding rate is of great significance for the farm to reasonably arrange the breeding time and improve the breeding efficiency.

Calculation formula

The monthly sow breeding rate can be calculated using the following formula:

Monthly breeding rate (%) = (actual number of breeding heads/theoretical number of breeding heads) * 100

Among them, the actual number of sows bred refers to the number of sows that are actually successfully bred, while the theoretical number of sows bred is the expected number of sows bred calculated based on the scale of the farm, breeding cycle and sow inventory.

Influencing factors

The monthly sow breeding rate is affected by many factors:

• Feeding and management : Appropriate feeding and management can improve the estrus rate and conception rate of sows, thereby increasing the monthly breeding rate.
• Breeding technology : Scientific breeding technology can improve the breeding success rate and thus increase the monthly breeding rate.
• Breeding pig quality : High-quality breeding pigs have higher conception rate and breeding success rate, which has a positive impact on the monthly breeding rate.
• Environmental conditions : Suitable environmental temperature, humidity, air quality and other conditions are conducive to the normal estrus and breeding of sows, and have a certain impact on the monthly breeding rate.

In summary, it is crucial to reasonably calculate and improve the monthly sow breeding rate for the economic benefits and sustainable development of the farm. Through scientific feeding management, excellent breeding technology, selection of high-quality breeding pigs and provision of suitable environmental conditions, the monthly sow breeding rate can be effectively improved, and ultimately the breeding benefits of the farm can be maximized.
