Section B
Question 2
Animal Nutrition
Alimentary Canals of Two Farm Animals
Type of digestive systems represented by:
- Ruminant
- Cattle/cows/sheep/goat/game
- Non-ruminant/monogastric animal
- Pig
Letter and name where hydrochloric acid is secreted in diagram A:
- D
- Abomasum/true stomach/milk stomach
Planning Fodder Flow Feed Flow and Fodder Flow Production
Definition of fodder flow:
- A strategic plan
- To ensure enough fodder
- To meet the requirements of all the animals
- Throughout the year
- In terms of quality and quantity (Any 2)
Aspects in planning for a fodder flow:
- Economic viability: The farmer to take measures of ensuring that the fodder is cost effective/cheap
- Sustainability: Planning to ensure that the fodder is always available to livestock
Digestibility Co-Efficiency
Calculation of digestibility co-efficiency:
DC
or %
Implication of the Answer in Question
The bulk of the feed (62,35 %) is digested and absorbed by the heifer
OR
The lesser percentage of the feed (37,65 %) was not digested hence not absorbed by the heifer
A Table on the Nutritive Ratio (NR)
The ration most suitable for the following:
- Fattening of old ewes β A
- Ewes in the last 4 weeks of pregnancy β B
- Young growing animals β B
Reason for the ration in 2.4.1 (a) :
- Ratio is wide
- Feed has higher lipid/carbohydrate/energy content
- Feed has lower protein content
- Ewes need more energy than protein (Any 1)
Ration with high levels of:
- Maize β A
- Fish meal β B
The implication of the nutritive ratio of ration B:
- Ration has higher protein content
- Recommended for growth, production, and reproduction
- Ration has lower lipid/carbohydrate/energy content (Any 2)
Diagram on Mineral Supplements
Method of mineral supplement:
Mineral lick
Two minerals that could be supplemented:
- Calcium
- Sodium
- Phosphorus
- Nitrogen (Any 2)
The partial protein substitute:
Non-protein nitrogenous substance (NPN) /biuret/urea
Role of growth regulators:
- Hormones β will stimulate metabolic reactions that will lead in increased growth rate
- Antibiotics β will provide immunity thereby increasing resistance to diseases
Question 3
Animal Production, Protection and Control
Animal Production Systems
Identification of animal production systems:
- A: Extensive production system
- B: Intensive production system
Comparison of the Two production systems:
- Capital investment β Low capital/technology input in extensive production system and large capital/technology input in intensive production system
- Area/space of land occupied β Low animal concentration in a large area in extensive production system and high animal concentration in a small area in intensive production system
Two examples of intensive production system:
- Cage
- Battery (layers/broilers)
- Deep litter system (Any 2)
Structures/Practices for Handling Animals
- A single strand of movable electrical wire
- A rope with a halter to tie animals to a pole
- A separate crush
- Single strand of movable electric wire
Scenario on Solar Radiation
Three measures to reduce heat stress under intensive conditions:
- Spray/Fugger with water
- Insulation
- Fans/conditioners/ventilators
- Housing systems/orientation (Any 3)
Correlation between high environmental temperature and feed consumption:
- The higher the temperature
- the less the feed intake
Data on Average Body Temperature and Pulse Rate in Dairy Cows
Line graph on the volume of stimulant and the growth response:
Line graph of growth stimulants against growth response Criteria/marking guidelines:
- Correct heading
- Y-axis β correct labelling (growth response)
- X-axis β correct labelling (volume of growth stimulants)
- Correct units
- Accuracy/correct plotting
- Line graph
