Study Notes
ANSCI 105: Poultry
- Course focuses on poultry management, specifically housing and environmental control for optimal bird health and productivity.
- Learning objectives encompass understanding poultry house design factors (climate, production, flock size), environmental control for bird health/productivity, effective litter management, and automation/technology in commercial operations.
Lesson 1: Design and Layout of Commercial Poultry Houses
- Poultry housing improvements in developing countries prioritize environments meeting birds' thermal needs.
- Newly hatched chicks require supplemental heat due to their poor temperature regulation (particularly in the first few days).
- Tropical climates often require cooling measures for birds.
- Large-scale commercial farms utilize climate-controlled structures (litter on floor or cage systems) for enhanced control. These operations are resource-intensive and require high turnover for viability.
- Medium-scale commercial farms in developing nations primarily rely on natural ventilation.
- Small-scale commercial (improved genotype stock and supplementary feeding): Structures vary, employing local materials. Structures may have several rooms for chick brooding and hen housing.
- Small-scale semi-scavenging system: Often utilize basic shelters made from local materials. Household flocks are kept in these shelters.
Lesson 2: Environmental Systems
- Ventilation management is critical for all poultry houses. This involves oxygen supply and removal of carbon dioxide, waste gases and dust.
- Large-scale operations often use negative pressure ventilation systems for air distribution, particularly for young chicks or colder climates.
- Tunnel ventilation is most effective for large houses in hot weather, drawing air through the house to remove heat, moisture, and dust.
- Evaporative cooling pads reduce air temperature by 10°C or more, depending on humidity.
- Fogging systems, best in dry climates, utilize high-pressure nozzles to disperse mist.
- Natural ventilation is common in smaller farms in areas with suitable climatic conditions.
Poultry Management
- Poultry management aims to create optimal conditions for maximum bird performance.
- Broody hens are often successful at hatching chicks.
- Artificial incubation success depends on proper management of temperature, humidity, ventilation.
- Poultry health monitoring, appropriate brooding/rearing/growing/laying conditions, and vaccinations are vital aspects of management.
- Breed effects are significant: Commercial hybrids thrive in optimal conditions but are less adaptable to tropical settings. Indigenous breeds are more adaptable and respond positively to better management.
- Temperature effects demand adjustments to ensure appropriate conditions in housing (heat & cold).
- Effects of nutrition: Diets must meet the nutrient needs of each bird age and breed. Smallholder systems prioritize locally sourced ingredients for profitability in developing countries.
- Hygiene: Maintaining a clean environment and equipment is crucial for reducing parasites, dust, and microbial contamination.
- Litter materials & management: Litter absorbs waste, making the floor easier to manage.
- Management of lighting: Daily and seasonal biological cycles in birds are regulated by light.
- Lighting programs vary but generally depend on breed, housing type, location and time of year.
- Stockpersonship: Well-trained and dedicated staff are essential for proper bird care ensuring birds receive proper nutrition, space, and protection to achieve maximum profitability.
Records
- Recordkeeping is crucial for problem identification and resolution.
- This includes monitoring production levels, monitoring birds' growth, feed/egg weights, and treatment application.
- Observation of and recording of health problems enables detection of health issues early.
