Animal Breeding I -Meaning & Types SS1 Livestock Farming Lesson Note

Now that we’ve learned how to house and feed our animals, the next big question is: How do we make more of them? More importantly, how do we make better versions of them?

Animal Breeding is the process of mating selected animals to produce offspring (babies) with better qualities—like cows that give more milk or chickens that grow faster.

Choosing the Best: Selection Methods

Before any breeding happens, a farmer must decide which animals are “good enough” to be parents. This is called Selection. It is like a talent hunt on the farm.

There are three main ways farmers select their best animals:

• Mass Selection: This is based on how the animal looks and performs (Physical Appearance). If a ram is big, has strong legs, and a wide chest, the farmer picks it to mate with the females.
• Progeny Selection: “Progeny” means children. Here, we judge the father or mother by how good their babies are. If a bull’s daughters all produce a lot of milk, then that bull is a “star” and is kept for breeding.
• Pedigree Selection: This is based on the family history or “family tree.” If an animal comes from a long line of champions, it is selected even if it is still young.

Natural Breeding (The Traditional Way)

This is the simplest form of breeding. It happens when a male (like a Bull) and a female (like a Cow) are allowed to mate naturally.

There are two ways to manage this:

1. Pasture Mating: The male is simply left in the field with a group of females. He finds the ones that are ready and mates with them.
2. Hand Mating: The farmer keeps the male and female separate. When the female is ready to mate, the farmer brings the specific male he has chosen to her. This is better because the farmer can keep records of exactly when the “pregnancy” started.

Artificial Insemination (AI) – The Modern Way

This might sound like science fiction, but it is very common in Nigeria today!

Artificial Insemination is the process of collecting semen (seeds) from a high-quality male and manually placing it into the reproductive tract of a female.

Why do farmers use AI?

• You don’t need to keep a dangerous male: Bulls and big boars (pigs) can be very aggressive. With AI, you don’t need to keep a male on your farm.
• One male can father thousands: In nature, a bull can only mate with one cow at a time. With AI, his semen can be divided into many “straws” and sent to hundreds of farms.
• No Travel Needed: You can buy the “seed” of a champion cow from Europe or America and use it to breed your local cows here in Nigeria.
• Prevents Disease: It stops the spread of sicknesses that animals pass to each other during natural mating.

Basic Breeding Terms to Know

To talk like a real breeder, you need to know these three words:

• Inbreeding: Mating animals that are closely related (like brother and sister). Warning: This is usually bad because it can make the babies weak or sickly.
• Outbreeding: Mating animals that are not related at all. This usually makes the babies stronger.
• Crossbreeding: Mating two different breeds. For example, mating a local Nigerian cow (which survives heat well) with a foreign “Holstein” cow (which gives lots of milk). The baby will hopefully be tough and give plenty of milk!

Summary: The Goal of Breeding

As a student of Agriculture, remember that breeding isn’t just about making “more” animals. It’s about Improvement.

If your father had 10 goats that were small, your goal as a modern farmer is to breed them so that your own 10 goats are twice as big and twice as healthy.

Class Discussion / Review

1. If you have a very big cock (male chicken) and you want all your future chicks to be big like him, which selection method are you using?
2. Give one reason why a farmer in a village might prefer Natural Breeding over Artificial Insemination.
3. Think about it: Why is “Crossbreeding” very popular in Nigeria? (Hint: Think about our hot weather and the high milk production of foreign cows).
