Statistical analysis based on historical data from 2019 to 2025 shows that there is a

[0] between Muyuan Foods’ breeding sow inventory and hog prices:

Analysis Indicator	Correlation Coefficient	P-Value	Statistical Significance
Muyuan Breeding Sows vs Hog Price	-0.9059	0.0129	Significant (p<0.05)
National Breeding Sows vs Hog Price	-0.7335	-	Negative Correlation
Muyuan Breeding Sows (1-year lag) vs Hog Price	-0.9075	-	Strong Negative Correlation

: For every 10,000-head increase in Muyuan Foods’ breeding sow inventory, hog prices show a downward trend after approximately 10-12 months, and vice versa. This pattern is highly consistent with the biological transmission cycle of pig breeding.

Breeding sow inventory is an

for judging hog prices, with its transmission mechanism as follows [1][2]:

Breeding Sow Restocking → Replacement Sow Cultivation (4 months) → Conception and Farrowing (114 days) → Piglet Fattening (6 months) → Market Hog Slaughter
     ↓
  Changes in breeding sow inventory are transmitted to changes in hog supply after approximately 10-12 months

According to data from the National Bureau of Statistics, the corresponding relationship between changes in breeding sow inventory and hog price peaks/troughs in each pig cycle is as follows [3]:

Phase	Capacity Change Period	Cumulative Change in Breeding Sows	Hog Price Peak/Trough
Phase 1	Dec 2017 - Sep 2019	-32.9%	38.71 yuan/kg (Oct 2019)
Phase 2	Sep 2019 - Jun 2021	+52.1%	11.54 yuan/kg (Oct 2021)
Phase 3	Jun 2021 - Mar 2022	-8.3%	27.66 yuan/kg (Oct 2022)
Phase 4	Mar 2022 - Dec 2022	+4.9%	14.19 yuan/kg (Jul 2023)
Phase 5	Dec 2022 - Apr 2024	-9.2%	20.92 yuan/kg (Aug 2024)
Phase 6	Apr 2024 - Present	+1.2%	Continuous Decline

: The breeding sow inventory hit a cycle low of 39.86 million head in April 2024, and hog prices peaked at 20.92 yuan/kg in August 2024, fully verifying the 10-12 month transmission lag.

Year	Breeding Sow Inventory (10,000 head)	YoY Growth (%)	Share of National Total (%)	Hog Price (yuan/kg)
2019	128.0	-	4.57	33.5
2020	216.0	+68.8	6.17	34.0
2021	283.0	+31.0	6.58	20.5
2022	314.0	+11.0	7.15	19.0
2023	313.0	-0.3	7.45	15.0
2024	351.2	+12.2	8.65	17.5
2025	323.2	-8.0	8.10	14.5

1. Rapid Growth Period (2019-2021)
   : Affected by African swine fever, industry capacity was in short supply. Muyuan seized the opportunity to expand rapidly, with breeding sow inventory increasing from 1.28 million head to 2.83 million head, representing a 121% growth.
2. Stable Period (2022-2023)
   : Industry capacity recovered, and Muyuan’s breeding sow inventory stabilized around 3.1 million head.
3. Re-expansion (2024)
   : Reached a peak of 3.512 million head at the end of 2024, with a YoY increase of 12.2%.
4. Active Reduction (2025)
   : Responding to policy calls, inventory dropped to 3.232 million head at the end of 2025, with a YoY decrease of 8.0%.

Muyuan Foods’ share of national breeding sow inventory increased from

to [0][4], reflecting its leading position in the industry’s large-scale development:

• 2020
  : Share reached 6.17%, exceeding 6% for the first time.
• 2024
  : Share hit a record high of 8.65%.
• 2025
  : Share fell slightly to 8.10% (due to active capacity reduction).

As of 2025, the breeding sow inventory of listed pig enterprises shows obvious differentiation [4]:

Enterprise	End of 2024 (10,000 head)	End of 2025 (10,000 head)	YoY Change
Muyuan Foods	351.2	323.2	-8.0%
Wens Foodstuffs	174.0	-	-
New Hope	75.0	<75	-

In 2025, hog prices showed an overall

[5]:

• Beginning of the Year
  : 16.0 yuan/kg
• Peak
  : Approximately 16.2 yuan/kg in March
• Trough
  : Approximately 11.5 yuan/kg in December
• Full-Year Average
  : Approximately 14.5 yuan/kg, a year-on-year decrease of 17.1%

1. High Capacity
   : National breeding sow inventory reached 40.39 million head at the end of Q1 2025, which is higher than the normal holding level of 39 million head.
2. Ample Supply
   : 2025 is a capacity release period, with ample hog supply in the market.
3. Weak Demand
   : Terminal consumer demand followed up with limited strength.

Guided by policies, pig enterprises responded to the call for “anti-involution” [6]:

• National breeding sow inventory dropped from 40.43 million head at the end of June 2025 to 39.9 million head at the end of October 2025.
• It fell below 40 million head for the first time.
• Hog supply is expected to decline in the second half of 2026.

---

• Hog Price Trend
  : Except for a short-term rise around the Spring Festival, the overall trend remains fluctuating downward.
• Inflection Point Expectation
  : Hog prices are expected to reach an inflection point around May 2025.
• Profit Cycle
  : The industry is expected to enter a profit cycle starting from July 2025 (based on the industry break-even line of 12 yuan/kg).

1. Smoother Cycles
   : The fluctuation range of the pig cycle will narrow, and the operating cycle will be lengthened.
2. Continuous Large-Scale Development
   : Industry concentration will further increase, with the market share of the top 20 enterprises exceeding 30%.
3. Cost Competition
   : Breeding efficiency (PSY, feed conversion ratio) has become the core competitive strength.

• Cost Advantage
  : The full cost was approximately 11.3 yuan/kg in October 2025, leading the industry [6].
• Scale Advantage
  : Slaughter volume increased from 18.11 million head in 2020 to 77.98 million head in 2025, representing a 330% growth.
• Technological Advantage
  : PSY is close to 30 head, significantly higher than the industry average.

1. Strong Negative Correlation
   : Muyuan Foods’ breeding sow inventory and hog prices show a significant strong negative correlation (r=-0.91).
2. 10-12 Month Transmission Lag
   : Changes in breeding sow inventory are transmitted to hog prices after approximately 10-12 months.
3. Increased Market Share
   : Muyuan’s share of the national total increased from 4.57% to 8.10%.
4. Near Cycle Inflection Point
   : With capacity destocking in the second half of 2025 and improved demand, hog prices are expected to rebound.

• Macroeconomic performance falls short of expectations, leading to continued weak terminal demand.
• Large-scale disease outbreaks affect production capacity stability.
• Fluctuations in raw material prices affect breeding costs.
