Uzbekistan’s poultry industry is in a period of aggressive expansion. As of October 2025, the country’s poultry population reached approximately 110 million birds, an 8.7% year-on-year increase, while total poultry meat production stood at roughly 800,000 tonnes with a government target of 1 million tonnes (source: avinews.com, “Poultry expansion stalls in Uzbekistan,” 2025). The government has introduced substantial incentives—including 50% reimbursement on feed costs and tax exemptions for poultry enterprises—to accelerate domestic self-sufficiency and eventually position the country as a regional exporter.

A landmark US$43 million joint venture between Uzbekistan’s Veterinary and Animal Husbandry Committee and India’s Avee Broilers, spanning the Jizzakh and Samarkand regions, aims to produce 4 million parent birds annually for the Central Asian market (source: UzDaily.uz, “New poultry production to be established in Uzbekistan”). Central Asia, with a population of 120 million, has an estimated demand of 1.2 million tonnes of poultry meat, of which roughly 200,000 tonnes are currently imported from Europe. The Samarkand region—historically known for agriculture—has become a focal point for poultry investment. It is in this context that SAMFARM (name anonymized at client request), a mid-sized poultry integrator with approximately 500,000 broilers in the Samarkand province, faced a critical production bottleneck: inconsistent feed grinding quality was undermining both pellet integrity and flock performance.

SAMFARM operates an on-site feed mill producing roughly 1,200 tonnes of broiler feed per month. The mill’s existing hammer mill, a locally sourced unit installed in 2019, had been showing signs of progressive degradation:

• Inconsistent particle size distribution. Routine laboratory checks using the ASAE S319.1 sieving methodology (14-screen stack, 10-minute shake) revealed a geometric mean diameter (GMD) drifting between 980 μm and 1,350 μm across batches. The coefficient of variation (CV) averaged 18.3%, well above the industry benchmark of <10% recommended by Hy-Line International.
• Excessive energy draw. The old grinder was consuming 9.8 kWh per tonne of ground corn at a 3.0 mm target screen, compared to the 5.5–8.5 kWh/ton range achievable with modern designs.
• Premature screen and hammer wear. Screens required replacement every 18–22 days, and the worn hammers produced a characteristic “tail” of oversized particles that compromised subsequent pelleting.

SAMFARM contacted Liyang Hongyang Feed Machinery Co., Ltd. (闳阳饲料机械) through a regional distributor in early 2026. Hongyang proposed the SFSP 112×40 drop-shaped hammer mill with the following configuration:

The relationship between grinding uniformity and animal performance is well-established. Coarse, inconsistent grinds reduce digestive enzyme action, while excessive fines increase passage rate, reducing nutrient absorption time. The key is not just the average—it is uniformity. A CV of 8.7% delivers predictable, consistent nutrition to every bird. Hongyang’s drop-shaped chamber design directly addresses the root cause of high CV values by breaking circular flow stratification.

Conclusion: A Partner in Feed Quality

SAMFARM’s experience illustrates that as Uzbekistan’s industry scales toward the 1 million tonne target, marginal gains translate to commercial advantage. Hongyang’s value proposition was not limited to delivering a machine but providing a quality-focused approach. For feed millers across Central Asia, access to precision grinding technology is critical to delivering consistent, competitive feed and healthy, productive flocks.
