Study Notes

Growth Rates in Beef Cattle

Bulls grow faster than steers primarily due to steers not producing testosterone, which inhibits their growth.
Steers exhibit reduced growth rates compared to bulls because of the absence of testosterone.

Carcass Quality Grading

The grading system assesses carcass quality based on the shape of the hind quarters and overall fat content.
The EUROP grading system uses letters, with 'E' representing the best quality.
Factors like percentage of fat and meat content are considered when grading carcass quality.

Target Weights and Characteristics

Heifers are typically assigned a target slaughter weight of 450 kg.
Beef breeds usually have short and wide heads, contrasting with dairy breeds that tend to have long and narrow heads.
The conformation of beef cattle refers to their shape and muscle distribution.

Slaughter Ages and Breed Differences

Beef cattle are generally slaughtered at ages ranging from 12 to 30 months.
Continental beef breeds are typically larger than British beef breeds.

Space and Weight Requirements

The minimum floor space required for weanlings is 1.4 m².
Spring-born suckler calves typically weigh between 40-50 kg at birth.

Daily Weight Gain

Autumn-born suckler calves gain more daily live weight compared to spring-born, averaging 1-1.2 kg per day.

Feeding and Breeding Practices

Fattening cattle require 0.4 m of feeding space.
Using a stock bull for breeding is cost-effective compared to artificial insemination.
A disadvantage of artificial insemination includes reliance on skilled technicians.

Hybrid Vigour

Hybrid vigour refers to the enhanced performance of offspring from heterozygous parents, leading to superior traits.

Calf Feeding Guidelines

A 45 kg calf should initially be fed 4.5 liters of whole milk per day.
Calves should receive milk in two meals, split between morning and evening to ensure consistent intake.

Weaning Practices

Gradual introduction to solid food is essential during the weaning process, while immediate pasture grazing should be avoided.
Careful handling and gradual weaning are critical for quality production in a calf-to-beef system.
