The yield of a herd
If you can sell each year many fat animals, the herd is said to
have a good yield.
A herd has a good yield:
· if you raise animals of a good
breed.
The animal husbandry service is finding out which breeds produce
most and thrive best in each region.
· if the animals grow quickly.
On the same pasture, all the animals do not gain weight as
quickly as each other.
You should keep only the offspring of males and females that
have grown quickly.
· if there are many dams which
give birth each year.
You must sell the old dams because they do not produce young any
more, they do not put on weight any more, and they eat a lot
You must also sell the surplus males; they eat but are no use.
You must keep the most fertile dams and make them breed.
A fertile dam gives birth every year.
· if the animals are well cared
for,
If you take good care of the herd, all the young grow up and
become strong animals.
Then you can sell them and earn a lot.
If many of the young animals die, the farmer does not earn as
much as he could.
In Africa many young animals die because of lack of care.
Even if diseases do not kill the animals, they do them a lot of
harm.
The animals become very weak and do not fatten much.
It takes a long time for animals that have been to fatten up for
sale.
If animals are well fed, and have enough to drink all the year,
they quickly become big and heavy.
If they are badly fed, and if they do not drink enough during
the dry season, they lose a lot of weight.
Animals lose in the dry season kilogrammes they have put on in
the rainy
season.
