NECO ANIMAL HUSBANDRY ANSWERS
================================
Animal Husbandry
(1ai)
-Cattle
-Fowl
(1b)
TABULATE
Inhalation:
-Sternum moves forward
-Diaphragm contracts and flattens out
-Intercostal muscles contract thus raised
Exhalation:
-Sternum moves backward
-Diaphragm relaxes and returns to its dome
shape
-Intercostal muscles relax and the ribs are
lowered
(1c)
-Scrotum: It protects the testes
-Seminal vesicle: It involved in the
production of fluid that
makes up the semen
(1d)
-The vulva becomes large,red and swollen
-Frequent urination and tail shaking
-There is undue noise making or bellowing
3b]Methods of rangeland improvement
(i) Rotational grazing:
- Rangeland is divided into units called paddocks.
- Animals are grazed on each paddock on rotational basis.
- Grazing in the rangeland should be planned and strictly adhered to.
- The previously grazed paddock should regenerate before the animals are returned there.
(ii) Reseeding
*.This is planting seeds of grasses and legumes in a depleted rangeland.
*.It is a way to improve the quality of the pasture with improved seeds of legumes and grasses.
*.The rangeland is allowed to rest for good growth of the sown grass and legume species.
(iii) Controlled stocking:
*.Number of animals in the range should be controlled.
*.Rangeland should be stocked to its maximum carrying capacity.
*.Overstocking should be avoided to check depletion of rangeland
*.Overstocking should be discouraged to prevent disease, pest and parasites infestations.
*.Overstocking may lead to soil degradation/erosion.


4a)
i)Breeding genomes to improve health, adaptability, and production.

ii) It Improves adaptability of animals to climate change and disease

iii) It leads to Improve in livestock breeds to allow greater feed efficiency and other desirable traits.

iv) It Ensure Only Animals( New Offspring ) With Desirable Character Are Produced.

v) It Leads To Increase In The Cattle Rearer Income...

4b)
i) The use of genetics not usually available on a local basis therefore artificial insemination is used.

ii) The production of replacement heifers with superior genetics call for the use of artificial insemination.


iii) The need for fewer bulls in the breeding season.

iv)Higher growth performance and calf value.
The production of calves for specialty markets such as club calves.

5ai)
i)to prevent biode-gradation (spoilage of harvested
fishes.
ii)it helps to kill micro-organism in the fish eg
bacteria
iii)it improves the quality of the fish
iv)it allow the fish to last longer than when its not
processed
v)fish processing like smoking allows huge
quantities of these fishes to be shipped(transported)
to long distance/market
5aii)
i)they should not be stressed up/weak breeders as
they may die leter
ii)they should be hardly and active fishes
iii)they must be disease free
iv)fish selected for brood stock purposes must be
wounds – free
v)fishes selected for brood stock purposes must be
of fairly bigin size
5bi)
i)spawning to ensure the survival of the species
ii)the sexes are usually kept seperate
iii)brood stocking
iv)brood stocking handling and acclimatisation/
conditioning
v)incubation of fertilized eggs
5bii)
i)fish smoking
ii)packaging of fish
iii)marketing of the fish
iv)filleting
v)refrigerating
