• Functions and deficiency symptoms of various nutritional elements.

 The following relevant questions and their answers in this topic will greatly motivate and help the  user to comprehend and understand the required concepts and practices;

1.  Give two ways by which production ration may be utilized by dairy goats

2.  Given that the livestock reared require a ration of 18% DCP and the farmer has maize bran of

 10% DCP and sunflower meal of 30% DCP. Use Pearson’s square method to calculate how

  much of the feedstuffs a 150kg rations  

3.  State the importance of the following in livestock nutrition: i) Water   ii) Vitamin A

4.  Name the compartment of the ruminant stomach where microbial digestion takes place.  

5.  i) A ration containing 18% protein is to be made from maize and sunflower cake. Given

  that maize contains 7% protein, and sunflower seed cake 34% protein. Use Pearson square

  method to calculate the value of feedstuffs to be used to prepare 100kgs of the feed  

 ii) A part from Pearson square method, name two other methods that can be used to formulate

feed ration

6.  (a) Define the term ration as used in livestock nutrition

 (b) A farmer wanted to prepare a 200kg of pig’s ration containing 16% D.C.P. Using the persons

square method, calculate the amount of maize containing 10% D.C.P and cotton seed

containing  28% D.C.P the farmer would need to prepare the ration (show your work)

7.  Give two livestock feed additives  

8.  State three factors that would determine the amount of concentrate fed to dairy cattle  

9.  State three factors that would determine the amount of concentrate fed to dairy cattle  

LIVESTOCK PRODUCTION II (NUTRITION) ANSWERS

1.  Production ration may be utilized by dairy goats in:

• Milk formation
• Growth

– Foetal/embryo development

2.  Use Pearson’s square method to calculate how much of the feedstuffs a 150kg rations  (5mks)

Maize bran = 12 x 150 = 90kg maize bran

20

Sunflower 8 x 150 = 60kg sunflower

20

3.    i) Water (1mrk)

• Transport medium
• For metabolic processes
• Regulates body temperature
• Maintains shell shape
• Component of livestock product
• Lubricant of body joints (2x ½ = 1mk)

  ii) Vitamin A (1mrk)

• Bone formation
• Prevents diseases / Increases disease resistance
• Improves vision

Improves vigour/ for proper growth

4.  Rumen.

5.  i) A ration containing 18% protein is to be made from maize and sunflower cake. Given

 that maize contains 7% protein, and sunflower seed cake 34% protein. Use Pearson square

 methods to calculate the value of feedstuffs to be used to prepare 100kgs of the feed (3mks)

ii) two other methods that can be used to formulate

feed ration

• Linear programming
• Trial and error

Graphical method.

6.  (a) The daily amount of food given to an animal/ the amount of food given to an animal

per day

(b) Quantity of maize = 12 x 200Kg

  18 = 133.33kg
