Dr. Muhammad Awais

2. Induced Molting
• Induced molting (or forced molting) is the
practice by the commercial egg industry
of artificially provoking a complete flock
of hens to molt simultaneously

3. Induce Molting Technique
• There are two methods of molting
1. By Fasting
2. By Nutrition restriction

4. By Fasting Method
• Which mean feed removal or starvation.
• In this method incorporated a 4-5 day feed removal along with 1-3 days
water removal.
• World wide the use of fasting is by far the most common method of induce
molting
• Disadvantage of this method is high mortality rate.

5. By Nutrition Restriction
• Induce a molting by providing a low-density diet
• Grape pomace
• Cotton seed meal
• Alfalfa meal

6. • Induce molting by dietary manipulation to create an imbalance of a
particular nutrient
• The most important among these include manipulation of minerals including
•Sodium (Na)
•Calcium (Ca)
•Iodine (I)
•Zinc (Zn)
• with full or partially reduced dietary intakes of these minerals

7. • Some programs combine feed withdrawal with a short period of water
withdrawal.
• Most programs also restrict the amount of lighting to provide a daylight
period that is too short to stimulate egg production
• Providing a simulated autumn, the natural time of molt and minimum egg
production.
