Feeding Regimes for Young Stock and Bulls
Introduction
Effective nutrition is vital for the development of young stock and bulls. Proper feeding regimes ensure optimal growth rates, reproductive health, and overall well-being. This guide provides detailed insights into the various stages of feeding cattle, from calves to mature bulls.
Importance of Nutrition in Young Stock and Bulls
Nutrition plays a fundamental role in the growth and development of young cattle. Insufficient nutrition can lead to stunted growth, poor health, and reduced fertility. Conversely, a well-balanced diet promotes healthy development and prepares bulls for breeding.
Nutritional Requirements for Young Stock
Calves (0-3 Months)
Colostrum Feeding
- Colostrum is crucial immediately after birth. It provides essential antibodies that boost immunity.
- Feed colostrum at a rate of 1/10th of the calf’s body weight within the first few hours.
Milk Feeding
- Transition to whole milk or milk replacer after colostrum.
- Maintain a daily intake of 4-6 liters per day based on calf size.
Solid Feed Introduction
- Introduce calf starter feed by two weeks old to promote rumen development.
- Offer high-quality hay gradually as calves grow.

Growing Bulls (3 Months to 1 Year)
Diet Composition
- A balanced diet should include high-quality forage and concentrates.
- Forages should be chopped to encourage intake; legume forages can enhance protein levels.
Concentrate Feeding
- Begin with about 0.75 kg of concentrate at four months, increasing to 3 kg by one year.
- Concentrates should contain 16% digestible crude protein (DCP) and 70% total digestible nutrients (TDN).
Growth Rate Goals
- Aim for an average daily gain (ADG) of 0.5 kg for optimal development.

Breeding Bulls (1 Year and Older)
Energy and Protein Needs
- Breeding bulls require higher energy and protein levels during the breeding season.
- A diet containing 10-11% protein and 60-70% TDN is recommended.
Diet Example
| Ingredient | Amount (lbs) |
| Rolled or Cracked Corn | 9.8 |
| Alfalfa Hay | 7.2 |
| Soybean Meal | 0.2 |
| Trace Mineralized Salt | 0.03 |
| Limestone | 0.02 |
Body Condition Monitoring
- Maintain bulls in good condition without allowing them to become overweight.

Specific Considerations in Feeding Regimes
Zinc Levels
Zinc is vital for male fertility. A deficiency can impair hormone production and spermatogenesis. Ensure diets are rich in zinc to support reproductive health in young bulls.
Supplementation Needs
During periods of low forage quality, particularly in winter or drought conditions, supplementation with energy and protein sources is necessary to meet growth targets.
Castration Timing
Castration should occur at 12-15 months for males intended for work. This timing optimizes growth potential without excessive fat deposition.
Feeding Schedule Overview
Calves (3 Months to 1 Year)
| Age (Months) | Green Fodder (kg) | Concentrate (kg) |
| 4 | 2 | 0.75 |
| 5 | 5 | 1 |
| 6 | 8 | 1.5 |
Adjust concentrate amounts based on forage quality.
Breeding Bulls (1 Year)
Bulls earmarked as future sires should receive liberal milk from birth to three months. Gradually introduce solid feeds by two weeks old.
Conclusion
Feeding young stock and bulls requires careful management of their nutritional intake to ensure optimal growth rates, reproductive health, and overall well-being. Regular monitoring of body condition scores can help guide dietary adjustments throughout their development stages.
