1.1. Core Poultry Terminologies and Classifications To understand poultry science, you must master the basic vocabulary used worldwide by veterinarians and farm managers. Key Vocabulary (Terminologies) • Poultry: Domesticated birds raised by humans for meat, eggs, or feathers (e.g., chickens, turkeys, ducks, geese, and guinea fowls). • Chick: A newly hatched or very young chicken of either sex (from day-old up to about 5-6 weeks of age). • Pullet: A young female chicken that has not yet started laying eggs (usually under 5–6 months old). • Hen: An adult female chicken kept mainly for egg production (usually over 5–6 months old). • Cockerel: A young male chicken under one year of age. • Rooster (or Cock): An adult male chicken over one year of age, kept for breeding. • Capon: A castrated (surgically castrated) male chicken, raised specifically for high-quality meat production. • Broiler: A chicken bred and raised specifically for fast growth and meat production (usually harvested at 6–8 weeks). • Layer: A chicken bred and managed specifically for high-volume egg production. • Flock: A group of poultry birds kept together on a farm. • Clutch: The total number of eggs laid by a bird on consecutive days before she stops to rest or sit on them. • Culling: The process of identifying and removing unproductive, sick, or poor-quality birds from the flock. [Day-Old Chick] ──► (If Male) ──► Cockerel ──► Rooster (Breeding) or Capon (Meat) ──► (If Female) ──► Pullet ──► Hen (Egg Layer) Commercial Classifications In commercial poultry production, chickens are classified based on their primary economic purpose: • Egg-Type Lines: Breeds selected strictly for efficient egg production (e.g., White Leghorn). They have small body weights and high feed-to-egg conversion rates. • Meat-Type Lines: Breeds selected for rapid muscle growth, high feed efficiency, and breast meat yield (e.g., Commercial Broilers like Ross or Cobb strains). • Dual-Purpose Lines: Breeds bred for both moderate egg laying and decent meat yield (e.g., Rhode Island Red, Australorp). These are highly useful in rural development programs. ________________________________________ please convert to slides and make it suatable for students with intermediate english and add important images and diagrams if any is required\

In commercial poultry production, chickens are classified based on their primary economic purpose:
• Egg-Type Lines: Breeds selected strictly for efficient egg production (e.g., White Leghorn). They have small body weights and high feed-to-egg conversion rates.
• Meat-Type Lines: Breeds selected for rapid muscle growth, high feed efficiency, and breast meat yield (e.g., Commercial Broilers like Ross or Cobb strains).

This guide covers essential poultry terminology and bird life stages, including definitions of key terms like flock and culling, and the progression from chick to adult birds. It also explores commercial poultry classes, comparing egg-type, meat-type, and dual-purpose breeds such as Leghorn and Ross, aiding in farm decision-making. Additionally, it examines the Ethiopian poultry industry's evolution, highlighting critical areas like feed and biosecurity, while leveraging data to inform...
