Study Notes
Common Beef Breeds
- Beef breeds classify into Continental and British categories.
- Notable Continental breeds: Charolais, Limousin, Simmental, Blonde d'Aquitaine.
- Prominent British breeds: Hereford, Aberdeen Angus, Shorthorn, Sussex.
- Each breed possesses unique characteristics affecting growth, meat quality, and hardiness.
Beef in Ireland
- Beef production in Ireland heavily relies on dairy cattle.
- Suckler herds contribute significantly, accounting for 25-30% of total production.
- Friesen calves are particularly suited for the continental veal market.
Beef Cattle Characteristics
- Dairy breeds possess narrow shoulders and hindquarters; beef breeds are wider and meaty.
- Beef cattle have shorter, broader heads and level, fleshed backs.
- Limb structure differs: dairy with strong yet sleek legs; beef with wide and deep legs.
Conformation
- Conformation refers to the physical shape and muscle distribution in cattle.
- Well-conformed animals lead to higher meat quality.
Beef Production Systems
- Cattle are typically slaughtered at 12 to 30 months based on breed and gender.
- Production systems vary in their growth management strategies.
Animal Growth & Development
- Bulls display the fastest growth rates but may exhibit aggressive behavior.
- Steers, being castrated males, have more regulated growth due to lack of testosterone.
Grading Carcase Quality
- EUROP grading system evaluates carcass length, hindquarter shape, fat percentage, and meat content.
- Each carcass is rated from E (best) to P (worst) based on quality metrics.
- Target weights at slaughter are 750kg for bulls, 550kg for steers, and 450kg for heifers.
Beef Production Systems in Ireland
- Irish beef production is mostly from dairy herds.
- Fattening space requirements per animal: 1.4 m² for weanlings and 2.0 m² for fattening cattle.
The Beef Production Year
- Spring calving leads to different management practices compared to autumn calving.
- Key management activities include feeding, health monitoring, and housing adjustments throughout the year.
Two Year Calf to Beef System
- Spring-born sucklers have a birth weight of 40-50kg, with a daily live weight gain (DLWG) of 0.8-1kg.
- Autumn-born sucklers weigh about 45kg at birth, with a DLWG of 1-1.2kg.
Calf Management
- Proper handling and gradual weaning are crucial when purchasing calves from dairy herds.
- Feeding colostrum and ensuring access to clean water and nutritious feed after weaning is essential.
Diseases in Cattle
- Cattle diseases can be viral, leading to weight loss, diarrhea, and other severe symptoms.
- Vaccination is a key preventive measure against infectious diseases.
- Notifiable diseases must be reported to agriculture authorities.
Biosecurity Measures
- Implement robust measures to prevent disease transmission within herds.
Selection of Female Breeding Stock
- Key factors in selecting breeding females include genetic stability, health history, and performance records.
Hybrid Vigour
- Hybrids exhibit enhanced traits such as growth rate and fertility compared to purebred counterparts.
Breeding Systems
- Options include stock bulls and artificial insemination (AI), each with distinct advantages and disadvantages.
- Achieving high conception rates is influenced by careful selection and management practices.
Breeding Programmes
- Effective breeding programs are designed to enhance genetic progress and overall herd health.
