Most Attention
The relationship between brooding and kill age
Ross Tech Notes April 2008
This lecture
•What is the goal for brooding?• Factors impact the goal • Best practices
The Goal
The Goal
7 days body weight of 0.425 lb. (190 grams)
4 - 5 times during the first 7 days
The Goal
• 1g at 7 days correspond to 6g at 37 days of age

The Goal
Ross Tech Notes April 2008
Why 7 Days?
Halevy et al. in American Society for Nutritional Sciences 2000• Fed or starved for 48 hours • Adult myoblast population (Satellite Cells) (SC)• Enabling increased muscle protein synthesis• Maximally active in this role during first wk
post-hatch• Starvation negatively impacts SC
Why 7 Days?
Why 7 days?Iji et al. in 2001 British Poultry Science• Proliferation• Hypertrophy • Increased rate of migration• Peaked at 7 days
The Goal
7 days body weight of 0.425 lb. (190 grams)
4 - 5 times during the first 7 days
Factors impact the goal
Factors impact the goal
• Factors out of your control• Factors under your control
Factors impact the goal
• Out of your control– Genetics– Breeder Age– Hatch window– Chick Quality– Transportation
Genetics
• Breeds intended for early kill age/low kill weight
• Slow feathering
• Easier to achieve 7 days Wight goal
Out of your control
• Breeder Age– hatching egg and chick size (3 weeks)
• Hatch window– 24 hours (dehydration)
– Early hatchers vs late hatchers
– Uniformity
• Chick quality– Physical quality (dehydration)
–Microbiological quality
• Transportation
Factors impact the goal
• Under your control– Temperature, ambient vs litter– Ventilation– Light– Feeder and drinker space– Crop Fill– Chick paper
Temperature: ambient vs litter

Ventilation
• Low pressurehttps://www.youtube.com/watch?time_continue=4&v=gbqWmUeIYCw
• Proper Ventilation https://www.youtube.com/watch?time_continue=1&v=BCj8lIusWCw

Light
• Duration à 23 hours• Activity à “driver that ensures adequate feed and water consumption

Cobb Academy 2015
• Intensity à 25 – 40 lux (2.5 – 4 foot candles)
Feeder and drinker space
• Review the numbers
• Drinkers are as important
• Feeding trays
• Extra drinkers
Crop Fill• First meal
• Full and soft
Chick paper
• Cover 25% - 100% of brooding area with paper. • Strong to last 5 days• Topped a few times a day• Get the birds firs meal
Summary• Goal is 0.425 lb. at 7 days• Muscle and intestinal development • Better weight, FCR, mortality and uniformity• Under your control– Brooding temperature – Litter temperature– Proper ventilation– Light intensity– Feeder Space– Crop fill– Chick paper
