Animal Eval notes Exam 2

What are the primary selection factors for beef cattle destined for market?

Muscle (meat/beef production) and fat levels.

What is the key to evaluating market cattle?

Weight optimization to maximize profitability while balancing cost and grading quality.

What does 'fattening pattern' refer to in cattle?

Cattle tend to accumulate fat from the front to the back, starting with the shoulders and brisket.

In beef cattle, what does optimal harvest time refer to?

The ideal moment to slaughter cattle to balance costs and quality.

How is muscle defined in cattle evaluation?

Muscle is round, while fat is flat.

What is the importance of the tail head and pins in evaluating fatness?

These areas are key indicators of fat accumulation in cattle.

What characterizes trim cattle in fat evaluation?

Trim cattle exhibit definition in the shoulder and a slightly bumpy topline.

What role does structure play in cattle evaluation?

Good structure enables cattle to carry weight and move efficiently.

How does cattle frame size relate to harvest readiness?

Frame size indicates when cattle will ideally be ready for harvest, typically around 1400-1450 pounds for choice grade.

What is the significance of muscle assessment in beef production?

Heavily muscled animals are generally preferred due to better meat quality and yield.

What impact does fatness have on beef quality?

Overly fat cattle are less efficient and can lead to discounts.

Define the term 'breeding cattle' in the context of selection criteria.

Breeding cattle are selected based on correctness, soundness, capacity, style, balance, muscling, and sex-specific traits.

What defines the Angus breed in terms of beef quality?

Angus cattle are known for their high-quality carcasses, particularly their marbling.

What is hybrid vigor in cattle breeding?

The phenomenon where offspring are better than the average of the parents, often enhanced through crossing diverse genetic lines.

What are composite breeds?

Breeds created by mixing two or more parental breeds to combine desired traits.

What is the significance of the brisket area in fat evaluation?

As cattle fatten, the brisket fills with fat, which can be an indicator of overall fat levels.

How do Belgian Blue cattle differ from other beef breeds?

Belgian Blues carry a myostatin gene that contributes to extreme muscle growth.

Describe Tarentaise cattle. What unique traits do they have?

Tarentaise cattle are known for their adaptability to high elevations and can carry the double muscle gene.

What is the ideal fat cover range for cattle at harvest?

Ideally about six-tenths of fat cover for optimal quality.

What does 'drop value' in cattle refer to?

The value derived from the off-fall of a carcass, including hide, blood, and organs.

Why is structural soundness crucial for cattle?

Good structural soundness is necessary for cattle to maintain mobility and carry weight effectively.

Compare the Red Angus breed with the Black Angus breed.

Both share many characteristics, but Red Angus developed from Black Angus cattle with a recessive gene for red hide.

What is the significance of muscle definition in younger cattle?

Younger animals show muscle development in areas like the forearm, which can indicate future growth potential.

What can be inferred from a cow with a large protruding brisket?

This could indicate that the animal is fatter.

What are the preferred characteristics of heifers for breeding?

Balance, femininity, smooth shoulders, and a straight top line.

Describe the typical color of Salers cattle.

Salers are typically dark mahogany red or sometimes black, known for their distinctive curly hair.
