2. Lungs

3. The Skin

The kidneys

The two kidneys excrete urine, which consists mainly of excess water, mineral salts and nitrogenous wastes from protein breakdown, urea and uric acid.

The lungs

The two lungs excrete carbon dioxide and water vapour.

The skin

The skin excretes sweat, which although more dilute, contains the same excretory substances as urine.

Foreign substances can be excreted in the hair and the nails.

(i)it contains the medulla which receives

impulse from the vertebral column

immunoglobulinswhch giv d calf immunity

frm bacteria infection

(ii) It contains high level of vitamin A which

help calf against infection

(iv) It has high levels of fat and protein for

nourishment

2a)

i)Creep-feeding is the practice of providing

supplemental feed to calves during the

grazing season in order to increase the

average daily gain and weaning weight

when calves are nursing their dams.

ii)steaming up the practice of commencing to feed extra

rations, especially of grain and

concentrates, to late pregnant cows in an

attempt to promote maximum milk

production from the very beginning of the

lactation.

iii) Flushing is an involuntary, temporary

reddening of the skin, usually of the face.

Facial flushing may be accompanied by

flushing of the neck or chest.

(3a)

Disadvantages:

(i) Unpredictable number of eggs are hatched

(ii)Process cannot be programmed

(iii) There is risk of predators /parasites

(iv) Not suitable for commercial production

(v) Low hatchability of eggs

(vi) Eggs are often exposed to adverse weather

conditions.

(3b)

(i) High room temperature

(ii) Crowding

(iii) Ventilation

(iv) Excess Bright light

(v) Feed availability

(vi) Water availability

(3c)

(i) Eggs are candled to determine the condition

of the air cell, yolk, and white

(ii) Candling detects bloody whites, blood

spots, or meat spots, and enables observation

of germ development.

=====================================

not be affected by a toxic plant or another.

-topography: cattle are known to prefer level to

gently rolling topography

-water:sheep and goats are known to tolerate

shortage of water more than cattle

-vegetative cover: sheep and goats feed better

on shorter forage species than cattle

(6c)

-rotational grazing

-continuous grazing

-rotation deferred grazing

(6d)

proper stocking

-brush and weed control

-better distribution of animals on the range

-they can give mechanical injury.
