Zebu
Overview
Zebu cattle (Bos indicus) are a distinct subspecies of domestic cattle originating from the Indian subcontinent, instantly recognizable by their prominent shoulder hump, large drooping ears, and loose, pendulous skin. Developed over thousands of years in tropical climates, Zebu cattle possess unparalleled heat tolerance, disease resistance, and ability to thrive in harsh conditions where European cattle (Bos taurus) struggle or fail. Zebu genetics form the foundation of tropical cattle production worldwide and are the basis for numerous American breeds including Brahman, Brangus, and Santa Gertrudis. While Zebu is technically a classification encompassing many Indian breeds rather than a single breed, these cattle share distinctive characteristics that make them essential for beef production in hot, humid climates across Africa, South America, Asia, and the American South.

Market Weight: 900-1,300 lbs at 18-30 months
Feed Efficiency: Excellent on forage-based diets
Growth Rate: Moderate; slower than European breeds
Vigor: Calves are hardy and disease-resistant
Temperament
Zebu cattle temperament varies significantly by breed and management. Some breeds like Gir are known for docility, while others can be more alert and reactive. Generally, Zebu cattle are intelligent and aware of their surroundings, with good memory for places and handling experiences. They can be calm and manageable when raised with consistent, gentle handling from birth.
Zebu cows demonstrate strong maternal instincts and are protective of calves. Bulls require careful handling and secure facilities, particularly during breeding season. The breed's intelligence means they respond well to patient, consistent handling but remember rough treatment. Overall temperament depends heavily on individual breed type, handling history, and management practices.
Meat Quality
Marbling: Generally less marbling than British breeds
Flavor: Good beef flavor, lean and flavorful
Tenderness: Variable; can be tender with proper management
Grading: Typically grades Select or lower due to leanness
Dressing Percentage: 50-60% (varies by breed and condition)
Lean Meat: Produces very lean beef with less external fat
Market Appeal: Preferred in many tropical countries
Crossbreeding: Best value often in crosses with British breeds
Feeding & Nutrition
