Methods of farm animal improvement - SS3 Agriculture Past Questions and Answers - page 1
What is the primary goal of farm animal improvement methods?
Reduce genetic diversity
Increase the cost of production
Enhance the quality and productivity of livestock
Decrease animal welfare
What can happen when farm animal selection focuses too much on a single trait?
Increased genetic diversity
Reduced productivity
Unintended negative consequences in other areas
Improved animal health
Why is careful record-keeping important in farm animal improvement?
It's not important at all
It helps increase genetic diversity
It's essential for tracking progress and making informed breeding decisions
It leads to decreased productivity
What is a potential disadvantage of intense selection or inbreeding in farm animal improvement?
Increased disease resistance
Improved animal welfare
Reduced genetic diversity
Faster genetic improvement
Which factor can be a motivation for selecting farm animals that are better suited to their local environment?
Unintended consequences
Adaptation to environmental conditions
Ethical concerns
Increased cost of production
What is the primary advantage of selecting animals with desired traits for breeding?
Reduced productivity
Increased genetic diversity
Improved genetic makeup over time
Decreased disease resistance
What is the purpose of farm animal improvement methods?
To reduce the number of animals on a farm
To make animals look more attractive
To enhance the quality and productivity of livestock
To increase the size of farm animals
Which disadvantage is associated with farm animal improvement methods?
Increased disease susceptibility
Loss of genetic diversity
Reduced adaptation to the environment
Lower cost of production
What can result from breeding for rapid growth in animals, such as chickens?
Increased disease resistance
Stronger bones
Unintended consequences like weaker bones
Reduced animal productivity
Why is breeding for disease resistance in farm animals advantageous?
It increases the need for costly treatments
It reduces the genetic diversity
It can result in healthier animals and cost savings
It leads to unethical practices
