Animal Nutrition II – Balanced Feed Ration & Storage SS1 Livestock Farming Lesson Note

In our last lesson, we talked about the “ingredients” like maize, fish meal, and salt. Today, we are going to learn how to mix them together like a chef to create a perfect meal for our animals. In farming, we don’t just throw food at animals; we give them a Ration.

What is a Balanced Ration?

A Ration is the total amount of food an animal eats in 24 hours.

A Balanced Ration is a meal that contains all the five classes of nutrients (Energy, Protein, Minerals, Vitamins, and Water) in the correct proportions for that specific animal.

• Maintenance Ration: This is just enough food to keep the animal alive and healthy—not to make it fat or produce eggs. It’s like a person eating just enough to stay awake.
• Production Ration: This is extra food given to animals that are “working.” For example, a hen laying eggs, a cow giving milk, or a pig being fattened for the Christmas market.

Factors Affecting Feed Formulation

When a farmer or a feed mill wants to “formulate” (mix) a bag of feed, they don’t just guess. They look at several things:

• The Age of the Animal: Baby chicks need lots of protein to grow muscles, while old hens need more minerals to make eggshells.
• The Species: You cannot give “Pig feed” to “Fish.” Their bodies are built differently.
• The Purpose of Production: Are you raising the animal for meat (Broilers) or for eggs (Layers)? Meat animals need more energy; egg animals need more calcium.
• Cost of Ingredients: A smart farmer looks for what is cheap and available. If maize is too expensive, they might use more guinea corn.
• Health Status: Sick animals might need special feed that is easier to digest or has extra vitamins.

How to Store Feed Properly

Feed is the most expensive part of farming. If you store it badly, it will spoil, grow mold, or be eaten by rats—and you will lose your money!

Rules for Good Feed Storage:

1. Keep it Dry: Never let rain or moisture touch the feed. Wet feed grows “Aflatoxins” (poisonous molds) that can kill your animals.
2. Use Pallets: Don’t put bags of feed directly on the cold cement floor. Put them on wooden planks (pallets) so air can circulate underneath.
3. Ventilation: The store must have fresh air. Heat can destroy the vitamins in the feed.
4. Pest Control: The store must be “Rat-proof” and “Bird-proof.” Rats don’t just eat the food; they also leave droppings that carry diseases.
5. First-In, First-Out (FIFO): Always use the old bags of feed before opening the new ones. Don’t let feed sit for more than 2-3 months.

Tools Used in Feed Preparation

On a big farm, you might see these machines:

• Grinding Machine (Hammer Mill): To crush maize and soybeans into powder.
• Mixer: A big machine that stirs all the ingredients together so the animal doesn’t just pick out the “tasty” parts.
• Pelletizer: A machine that turns the powdered feed into small “pills” or pellets that are easy for fish or rabbits to eat.

Summary for the Student

A farmer is like a doctor. By looking at the animal’s age and what it is producing, you decide what goes into its “bowl.” Remember: Garbage in, garbage out. If you give your animals poor, moldy, or unbalanced feed, they will grow slowly and you will not make a profit.

Class Activity

1. The “Recipe” Game: If you have a bag of maize (Energy) and a bag of Groundnut Cake (Protein), and you want your pigs to get very fat, which bag will you use more of? Why?
2. Observation: Look at a bag of commercial feed. Read the “Guaranteed Analysis” on the label. What is the percentage of Protein?

Homework: Draw a simple sketch of a feed store. Show where the windows should be and how the bags should be stacked on pallets.
