Worked Solution & Example Answer:Outline the precautions taken to reduce mortality at calving time in a dairy herd - Leaving Cert Agricultural Science - Question 6 - 2007
Step 1
Outline the precautions taken to reduce mortality at calving time in a dairy herd.
Answer
To minimize mortality during calving, several precautions are essential:
- Correct Age at Calving: Ensure cows are of the appropriate age before breeding.
- Correct Weight of Cow: Maintain an adequate body condition to support the calving process.
- Calving Environment: Prepare a clean and safe calving area, ensuring it is free from hazards.
- Regular Monitoring: Conduct regular checks to identify signs of calving distress or complications.
- Calving Assistance: Be equipped to assist with calving if complications arise, potentially using a calving jack.
- Health Precautions: Isolate sick cows and keep accurate records of calving dates for better management.
- Nutrition Management: Provide appropriate diet and feeding prior to calving to ensure cows are in optimal health.
Step 2
In a beef suckler system, describe the management practices necessary to achieve high levels of production.
Answer
Effective management practices crucial for high production in a beef suckler system include:
- Proper Nutrition: Ensure cows are on a balanced diet for optimal health and reproductive efficiency.
- Heat Detection: Regularly monitor cows for signs of heat to optimize breeding intervals.
- Breeding Management: Use high-quality bulls and maintain records related to bull fertility and breeding history.
- Housing and Environment: Provide appropriate housing that minimizes stress and disease transmission.
- Grazing Management: Implement effective grazing strategies to maximize pasture utilization and avoid overgrazing.
- Health Monitoring: Maintain a robust health management program, including vaccinations and disease control measures.
Step 3
What is meant by a body condition score?
Answer
A body condition score (BCS) is a subjective measure used to evaluate the fat cover and overall condition of an animal. It helps assess the health and nutritional status, providing insights into whether an animal is underweight, ideal, or overweight. BCS is typically scored on a scale, with higher scores indicating better body condition.
Step 4
What is the relationship between body condition score and milk yield in the data above?
Answer
The data indicates a correlation between body condition score and milk yield. Specifically, treatment B, which has a higher BCS of 3.00, exhibits a higher milk yield of 26.50 kg/cow/day compared to treatment A with a BCS of 2.73, yielding 25.50 kg/cow/day. This suggests that better body condition may enhance milk production capabilities.
Step 5
Step 6
State two factors, other than BCS, that may influence the percentage fat in milk.
Answer
Two factors that may influence the percentage fat in milk, excluding body condition score, are:
- Genetics of the Cow: Different breeds or genetic lines can produce varying levels of milk fat.
- Stage of Lactation: The stage of the lactation cycle can alter milk composition, including fat content.
