Worked Solution & Example Answer:a) Name any three ingredients, apart from minerals, that you would find in a sheep concentrate and explain why each one of them is present - Leaving Cert Agricultural Science - Question Question 1 - 2008
Step 1
a) Name any three ingredients, apart from minerals, that you would find in a sheep concentrate and explain why each one of them is present.
Answer
-
Barley or Oats: These grains serve as a source of carbohydrates and fiber, providing energy essential for growth and maintenance.
-
Soya Bean: This ingredient offers protein, which is crucial for growth and tissue repair in sheep.
-
Molasses: This is included for its sugar content, which is a quick source of energy and enhances palatability.
Step 2
b) Name four factors that influence the feeding value of silage.
Answer
-
Adequate Fertilization: Proper application of nitrogen (N) and potassium (K) ensures optimal growth and nutrient value.
-
Timing of Harvest: If silage is cut too late, the digestibility and Dry Matter Digestibility (DMD) will decline.
-
Type of Grass Used: Different grass species have varied energy profiles; for example, Italian ryegrass has higher energy content.
-
Fermentation Process: The effectiveness of the fermentation process influences nutrient retention and overall quality.
Step 3
c) Outline the changes that occur in the diet of a lamb during its first six months.
Answer
In the first few weeks, lambs primarily consume colostrum, which is rich in antibodies. As they grow, they gradually transition to milk, which remains their main nutrient source until about three months. After this period, they begin to graze on grass and receive concentrates, facilitating their growth as they adapt to solid food.
Step 4
d) Name one disease caused by the lack of a mineral in any animal and explain how it affects this animal.
Answer
One disease is milk fever, which is caused by a deficiency of calcium. This condition typically affects lactating cows and is characterized by muscle weakness and inability to stand. It can lead to severe health complications if not addressed, requiring prompt medical intervention.
