SECTION C: (40 Marks)

Answer only two questions in this section in the spaces provided. (40MARKS) Answer only two questions in this section in the spaces provided.

(a). Characteristics of merino sheep.

-Small in body /angular in form.

-Drooping rump.

-Narrow in the chest-close together front.

-Muzzle flesh colored.

-White hooves, wool and horns.

-Slow maturing.

-Lambing percentage of 100.

-Hardy breed does well under extensive conditions.

-Have good flocking instincts.

-They produce fleece that is highly valued.(First 6 x 1 = 6 marks)

(b). State and explain possible reasons for maintaining farm tools equipment.

-To increase durability. Properly and well maintained and cared tools last longer in the farm. They give the farmer a long service.

-To reduce the replacement cost. Tools and equipment are expensive to buy and replace. If well taken care of they last and the farmer does not spend capital replacing them. This reduces the total cost of production in the farm.

-Increased efficiency. Well maintained tools work better and more efficiently to give a clean, well finished piece of work. Poorly kept tools are often toot difficult to work with and require a lot of energy.

-To avoid injury to the user. Using a poorly maintained tool might result to injury of the user e.g using a blunt cutting tool which has a broken handle leads to development of blisters on the hand of the user. If well maintained, tools become safe to use.

-To avoid damage to the tool. Poorly maintained tools get damaged easily.

(Stating 5 x 1 = 5 marks)

Total 10 marks

(c).Procedure of training a calf for bucket feeding.

-Wash and disinfect the hands to the used.

-Put milk in a clean shallow bucket.

-Push calf backwards to the corner of the calf pen.

-Holding the bucket with the left hand, dip two or three fingers of the right hand into the milk and then place the finger into the mouth of the calf to suck.(do this repeatedly.)

-Slowly guide the calf into the milk bucket by lowering fingers into the bucket while the calf still sucks the fingers.

-Ensure the calf’s head is slightly raised. This allows it to suck readily.

(iii).Highly palatable. - Encourages the animal to eat with relish.
