Description
🐂 VACA–X BREED
(Hybrid line developed from the Bulgarian Grey Cattle foundation)
The Bulgarian Grey Cattle is a well-known breed with exceptionally strong muscular development. Mature bulls typically reach 600–700 kg, and the breed is highly valued for its adaptability, resilience, and long lifespan — making it an ideal genetic foundation for high-performance cattle in Vietnam.

1. Origin & Breed Characteristics
Bulgarian Grey Cattle originate from the mountainous regions of Bulgaria, where the climate ranges dramatically from –10°C to 40°C. Living in such harsh conditions has shaped this breed with exceptional traits:
-
High endurance and physical resilience
-
Excellent tolerance to both cold and heat
-
Strong natural disease resistance
These attributes make Bulgarian Grey an ideal foundation for developing the VACA–X breed — engineered for comprehensive adaptability in Vietnam’s diverse environments.
2. Key Characteristics
• Outstanding reproductive performance
Bulgarian Grey cattle are hardy, easy calvers, and maintain stable fertility for exceptionally long periods — up to 20 years.
• Wide environmental adaptability
They thrive in both cold mountain climates and hot, humid regions. Their strong constitution reduces veterinary costs and minimizes health risks.
• High-quality beef
-
Firm, flavorful, nutrient-rich meat
-
Naturally raised on open pastures
-
Light natural marbling for tenderness without excessive fat
-
Highly regarded in the clean beef, herbal-fed beef, and pasture-raised beef segments
3. Value of Crossbreeding into VACA–X
Using Bulgarian Grey as the genetic foundation provides significant advantages for the VACA–X line:
-
Fast growth with excellent muscle conformation
-
Consistent meat quality — ideal for commercial demand
-
High tolerance to harsh environments — suitable for both small farms and large-scale operations
-
Strong heritability ensuring a sustainable and reliable breeding source
