Lesson summary

Animal production is an important part of Ghana’s food system and economy. Many homes and communities keep animals such as chickens, goats, sheep, pigs, rabbits and fish for meat, eggs, milk and income. The success of animal production depends greatly on feeding—choosing the right type of feed for the right type of animal, and ensuring the feed contains the right nutrients in correct proportions. If animals are fed wrongly, they grow slowly, fall sick, lay fewer eggs, produce less milk, or even die—leading to financial loss.

Lesson notes

A. Key Terms Animal feed: Any material eaten by animals to provide nutrients for growth, energy, reproduction, and health. Nutrients: Useful substances in feed needed by animals (e.g., protein, carbohydrates). Ration: The amount of feed given to an animal in a day. Balanced diet (for animals): Feed that contains all essential nutrients in the right amounts. Ruminants: Animals with a four-chambered stomach that can digest fibrous feed (e.g., cattle, sheep, goats). Non-ruminants (monogastrics): Animals with a single stomach; they digest concentrates better than rough fibrous feed (e.g., pigs, poultry). Concentrates: Feeds high in nutrients and low in fibre (e.g., maize, wheat bran, fish meal). Roughages (forages): Feeds high in fibre (e.g., grasses, hay, silage, crop residues).

B. Types of Animal Feed (and how they differ) 1) Roughages / Forages (High fibre) Examples in Ghana: Fresh grasses (elephant grass), legumes (stylo), pasture Hay (dried grass) Silage (fermented chopped grass/maize) Crop residues: maize stover, rice straw, groundnut haulms

Characteristics: High fibre, bulky Lower energy per kilogram than concentrates Best for ruminants because they can digest cellulose using microbes in the rumen

Suitable animals: Cattle, sheep, goats (ruminants) Rabbits can eat some roughage but still need quality nutrients

Evaluation guide

• Match the different types of feed with different types of animals.
• Discuss the types of nutrients and their sources in the different types
• of animal feed.
• Select and discuss appropriate feed for animal based on the
