Why Sows Fail to Come into Estrus?

1. Nutritional Imbalance & Poor Body Condition

Lack or excess of protein, vitamin E, selenium disrupts hormones and stops estrus.

Sows that are too fat or too thin cannot cycle normally.

Solution:

(1)Use Swine Ultrasound Machine to measure backfat.Ideal backfat: 16–18 mm for breeding readiness.

(2)Feed balanced, stage-specific diets based on real- time body condition.

2. Poor Housing & Environment

Solution:

(1)Ideal Temperature: 18–22°C

(2)Ideal Lighting: 14–16 hours per day

(3)Good ventilation, clean housing, low stress

(4)Exercise: 1–2 hours daily

3. Infectious Diseases

 Classical Swine Fever (CSF), PRRS (Blue Ear Disease) and other infections.

Solution:

(1)Regularly vaccinate the pigs

(2)Disinfect Regularly

4. Reproductive System Problems

Reproductive System Problems like Ovarian cysts, endometritis directly block estrus.These disorders damage cannot be observed by our eyes .So we must diagnose it with the help of  Swine Ultrasound Machine.

Solution:

We must use Swine Ultrasound Machine to Check the condition of follicles and backfat thickness.

After all,most sow anestrus issues can be accurately diagnosed  with Swine Ultrasound Machine .It helps you judge nutrition, body condition, ovarian status, and reproductive health — all in one device.Scientific breeding + Swine Ultrasound Machine = higher efficiency, lower costs, better production.
