Q1
Easy
Which of the following practices is primarily aimed at improving the yield of dairy cattle?
A.
Selective breeding
B.
Crop rotation
C.
Hydroponics
D.
Intercropping
Show Answer & Explanation
Correct Answer: A
Selective breeding involves choosing specific animals with desirable traits to reproduce, which can increase milk production in dairy cattle.
Q2
Easy
What is the primary reason for the process of artificial insemination in livestock?
A.
To improve animal health
B.
To increase genetic diversity
C.
To enhance milk production
D.
To control breeding timing
Show Answer & Explanation
Correct Answer: B
Artificial insemination allows the introduction of superior genetics from various animals, thus increasing genetic diversity and overall productivity.
Q3
Easy
Which of the following is NOT a benefit of adopting modern animal husbandry techniques?
A.
Increased milk production
B.
Higher disease resistance
C.
Reduced environmental impact
D.
Lower initial investment costs
Show Answer & Explanation
Correct Answer: D
Modern animal husbandry techniques often require significant initial investment, such as infrastructure and technology, unlike traditional methods that may have lower costs.
Q4
Medium
Which of the following is NOT a method of controlling diseases in livestock?
A.
Vaccination
B.
Quarantine
C.
Selective breeding
D.
Hygiene management
Show Answer & Explanation
Correct Answer: C
Selective breeding is primarily focused on improving traits like growth and productivity, not directly controlling diseases.
Q5
Medium
What is the primary goal of artificial insemination in animal husbandry?
A.
To increase genetic diversity
B.
To reduce the cost of breeding
C.
To introduce desirable traits
D.
To eliminate diseases
Show Answer & Explanation
Correct Answer: C
Artificial insemination allows for the introduction of superior genetics into a breeding population, enhancing desired traits.
Q6
Medium
Which breed of sheep is primarily known for its fine wool production?
A.
Merino
B.
Suffolk
C.
Dorset
D.
Hampshire
Show Answer & Explanation
Correct Answer: A
Merino sheep are well-recognized for producing high-quality fine wool, which is highly valued in the textile industry.
Q7
Medium
Which of the following is a common practice to enhance milk production in dairy cows?
A.
Reducing feeding
B.
Improved genetic selection
C.
Increased stress levels
D.
Decreased milking frequency
Show Answer & Explanation
Correct Answer: B
Improved genetic selection involves choosing cows with high genetic potential for milk yield, which directly enhances production.
Q8
Hard
Which of the following is NOT a method of selective breeding in animals?
A.
Inbreeding
B.
Cross-breeding
C.
Hybrid vigor
D.
Outcrossing
Show Answer & Explanation
Correct Answer: C
Hybrid vigor refers to the improved or increased function of any biological quality in a hybrid offspring. It is not a breeding method but an outcome of breeding.
Q9
Hard
What is the primary purpose of artificial insemination in animal husbandry?
A.
To increase genetic diversity
B.
To prevent diseases
C.
To enhance fertilization rates
D.
To decrease breeding costs
Show Answer & Explanation
Correct Answer: C
Artificial insemination is primarily used to enhance fertilization rates by ensuring that sperm is introduced directly into the reproductive tract, improving the chances of conception.
Q10
Hard
Which hormone is primarily responsible for the development of male secondary sexual characteristics in cattle?
A.
Estrogen
B.
Testosterone
C.
Progesterone
D.
Oxytocin
Show Answer & Explanation
Correct Answer: B
Testosterone is the primary male sex hormone that promotes the development of male secondary sexual characteristics in cattle.
