Study Notes
Disease Management
- Importance: Disease management is critical in broiler chicken production to prevent economic losses and ensure animal welfare.
- Key diseases:
- Infectious bronchitis
- Newcastle disease
- Infectious laryngotracheitis
- Avian influenza
- Necrotic enteritis
- Control measures:
- Vaccination programs
- Biosecurity protocols (e.g., sanitation, isolation, and hygiene)
- Antibiotic use (judicious and responsible)
- Monitoring and surveillance
Housing Systems
- Types:
- Conventional (deep litter or slatted floors)
- Enriched (perches, nesting boxes, and litter)
- Free-range or organic (outdoor access)
- Cage-free or aviary systems
- Factors to consider:
- Space allocation and stocking density
- Ventilation and air quality
- Lighting and temperature control
- Litter management and waste disposal
Feeding Strategies
- Nutritionally balanced diets:
- Protein sources (e.g., soybean meal, corn, and wheat)
- Energy sources (e.g., corn, wheat, and fats)
- Vitamins and minerals
- Feeding regimens:
- Starter, grower, and finisher diets
- Phase feeding (different diets for different growth stages)
- Restrictive feeding (to control growth rate and body composition)
Meat Quality Control
- Factors affecting meat quality:
- Genetics and breeding
- Nutrition and feeding strategies
- Housing and environmental conditions
- Slaughter and processing methods
- Quality control measures:
- Microbiological testing (e.g., Salmonella and Campylobacter)
- Physical characteristics (e.g., weight, yield, and color)
- Sensory evaluation (e.g., texture and tenderness)
Egg Fertilization
- Not applicable to broiler chickens, as they are not bred for egg production.
Digestion of Chicken
- Monogastric digestive system:
- Mouth and esophagus
- Crop and proventriculus
- Gizzard and small intestine
- Large intestine and ceca
- Key digestive enzymes:
- Amylase
- Protease
- Lipase
Pen Design
- Factors to consider:
- Space allocation and stocking density
- Litter management and waste disposal
- Ventilation and air quality
- Lighting and temperature control
- Pen design types:
- Single-tier or multi-tier systems
- Aisle or gangway systems
General Health of Broilers
- Health indicators:
- Mortality rates
- Morbidity rates
- Body weight and growth rate
- Feed conversion ratio
- Health monitoring and surveillance:
- Regular health checks and inspections
- Monitoring of disease incidence and prevalence
Processing of Chickens
- Slaughter and processing methods:
- Humane stunning and killing
- Evisceration and processing
- Cleaning and sanitizing
- Packaging and labeling
- Food safety and regulations:
- Compliance with regulatory standards
- Hazard Analysis and Critical Control Points (HACCP)
Disease Management
- Disease management is critical in broiler chicken production to prevent economic losses and ensure animal welfare.
- Key diseases affecting broiler chickens include infectious bronchitis, Newcastle disease, infectious laryngotracheitis, avian influenza, and necrotic enteritis.
- Control measures for disease management include vaccination programs, biosecurity protocols, antibiotic use, and monitoring and surveillance.
Housing Systems
- There are four main types of housing systems for broiler chickens: conventional, enriched, free-range or organic, and cage-free or aviary systems.
- Factors to consider when designing housing systems include space allocation, stocking density, ventilation, air quality, lighting, temperature control, and litter management.
Feeding Strategies
- Nutritionally balanced diets for broiler chickens include protein sources, energy sources, vitamins, and minerals.
- Feeding regimens include starter, grower, and finisher diets, phase feeding, and restrictive feeding to control growth rate and body composition.
Meat Quality Control
- Factors affecting meat quality include genetics, breeding, nutrition, feeding strategies, housing, and environmental conditions, and slaughter and processing methods.
- Quality control measures include microbiological testing, physical characteristics evaluation, and sensory evaluation.
Digestive System
- Broiler chickens have a monogastric digestive system consisting of mouth, esophagus, crop, proventriculus, gizzard, small intestine, large intestine, and ceca.
- Key digestive enzymes include amylase, protease, and lipase.
Pen Design
- Factors to consider when designing pens include space allocation, stocking density, litter management, ventilation, air quality, lighting, and temperature control.
- Pen design types include single-tier or multi-tier systems and aisle or gangway systems.
General Health of Broilers
- Health indicators for broiler chickens include mortality rates, morbidity rates, body weight, growth rate, and feed conversion ratio.
- Health monitoring and surveillance involve regular health checks and inspections, and monitoring of disease incidence and prevalence.
Processing of Chickens
- Slaughter and processing methods include humane stunning and killing, evisceration, processing, cleaning, sanitizing, packaging, and labeling.
- Food safety and regulations involve compliance with regulatory standards and Hazard Analysis and Critical Control Points (HACCP).
