Animal production

Introduction

Animal production is a crucial component of agriculture that involves the breeding, rearing, and management of livestock for various purposes such as food, fiber, labor, and companionship. In this topic, we will delve into the key concepts of animal production, including different production systems, breeds of animals, feeding practices, and health management.

Animal Production Systems

Intensive System

In the intensive system, animals are raised in confinement with controlled conditions. This system aims to maximize production output per unit area or animal. Examples include feedlots for cattle and battery cages for poultry.

Example: In an intensive dairy farming system, cows are housed in barns and fed a balanced diet to maximize milk production.

Extensive System

The extensive system involves animals being raised in open pastures with minimal human intervention. Animals graze freely and rely on natural resources for their feed. This system is suitable for areas with ample grazing land.

Example: Maasai pastoralists in Kenya practice extensive livestock farming, where their cattle roam freely in search of pasture and water.

Breeds of Livestock

Indigenous Breeds

Indigenous breeds are well adapted to local conditions and are often resistant to diseases prevalent in the region. They are valuable for their hardiness and ability to thrive in harsh environments.

Example: The Boran cattle breed in Kenya is known for its tolerance to heat and resistance to tick-borne diseases.

Exotic Breeds

Exotic breeds are introduced from other countries for their high productivity traits such as faster growth rate or higher milk yield. They are often crossbred with indigenous breeds to improve overall performance.

Example: The Holstein-Friesian dairy cattle breed is commonly used in Kenya for its high milk production potential.

Feeding Practices

Balanced Diet

Livestock require a balanced diet consisting of carbohydrates, proteins, fats, vitamins, and minerals to support growth, reproduction, and overall health. Feed formulation should meet the specific nutritional requirements of each animal species.

Example: A balanced diet for broiler chickens may include corn (carbohydrates), soybean meal (protein), and mineral supplements.

Rationing

Rationing involves providing animals with the right amount of feed to meet their nutritional needs. Overfeeding or underfeeding can lead to health issues and reduced productivity.

Example: A dairy cow may be given a specific amount of concentrate feed along with good quality forage to meet its energy and protein requirements.

Animal Health Management

Vaccination

Vaccination is essential to prevent common diseases and ensure the overall health of livestock. Vaccination schedules should be followed to protect animals from infectious diseases.

Example: Calves are vaccinated against diseases like blackleg and anthrax to boost their immunity.

Parasite Control

Parasites such as worms and ticks can affect the health and productivity of livestock. Regular deworming and use of acaricides help control parasite infestations.

Example: Sheep are dewormed periodically to prevent internal parasite infections.

Common Mistakes

• Neglecting proper vaccination schedules can lead to disease outbreaks.
• Overfeeding animals can result in obesity and health issues.
• Ignoring parasite control measures can reduce livestock productivity.

Key Points

• Animal production involves breeding, rearing, and managing livestock for various purposes.
• Different production systems include intensive and extensive systems.
• Indigenous and exotic breeds are utilized in livestock farming.
• Feeding practices should focus on providing a balanced diet and proper rationing.
• Animal health management involves vaccination and parasite control.

Practice Questions

1. Explain the differences between the intensive and extensive animal production systems. Answer: The intensive system involves raising animals in confinement with controlled conditions, while the extensive system allows animals to graze freely in open pastures.

2. Why are indigenous breeds important in livestock farming? Answer: Indigenous breeds are well adapted to local conditions and often resistant to prevalent diseases, making them valuable for their hardiness.

3. What is the significance of vaccination in animal health management? Answer: Vaccination helps prevent common diseases and ensures the overall health of livestock by boosting immunity.

4. Describe the feeding practices that should be followed in dairy cattle farming. Answer: Dairy cattle should be provided with a balanced diet consisting of carbohydrates, proteins, fats, vitamins, and minerals, along with proper rationing to meet their nutritional requirements.

5. How does parasite control contribute to the productivity of livestock? Answer: Controlling parasites through regular deworming and use of acaricides helps prevent health issues and maintains the productivity of livestock.
