Worked Solution & Example Answer:The Friesian cow is described as a dual-purpose breed - Leaving Cert Agricultural Science - Question 6 - 2013
Step 1
Explain the term dual-purpose in this context.
Answer
The term 'dual-purpose' in the context of the Friesian cow refers to its ability to produce both milk and beef efficiently. This breed is valued not only for its high milk yield but also for its substantial meat quality, making it versatile for farmers who seek both dairy and meat production from the same herd.
Step 2
What is the expected milk yield in litres per lactation for a high yielding Holstein-Friesian cow?
Answer
The expected milk yield for a high yielding Holstein-Friesian cow is between 6,000 litres and 12,000 litres per lactation cycle. This yield can vary based on factors such as genetics, nutrition, and management practices.
Step 3
Step 4
Outline any two reasons for culling cows.
Answer
-
Age: As cows age, their productivity tends to decrease, leading farmers to cull older animals to maintain overall herd efficiency.
-
Health issues: Cows suffering from diseases, infertility, or lameness may be culled to prevent the spread of illness and maintain herd health.
