VI. HOW TO MAXIMISE LIVABILITY
- Delay sexual maturity . Use long step down light programme
- Age at housing must be at least 2 weeks before first eggs(16 weeks) to avoid mortality due to egg yolk peritonitis. If not able to so, delay start of lay using SODESMEA programme.
- Reduce light intensity 10/14 days after housing or use red light - Reduce light intensity 10/14 days after housing or use red light
- Maximise body weight in growing
- Good Beak trimming : - if made once it shall be conducted at 7 -10 days - if done twice it shall be done twice at 7/10 days (light) and at 8 - 10 weeks (severe) . Beak trim shall not be
conducted after 10 weeks of age.

SODESMEA TREATMENT PROTOCOL TO DELAY SEXUAL MATURITYSoft Delay of Sexual MaturityTO DELAY SEXUAL MATURITY BY USE OF FEED RESTRICTION
In cases where daily production of a flock is less than 2% daily .(not more than 5% daily) , thefollowing program can be used to delay sexual maturity. Seven (7) to ten (10) days:
3 day program = 5 - 7 days delayed4 day program = 7 - 10 days delayed5 day program = 10 - 14 days delayed
EXEMPLE OF A 4 DAY PROGRAM FOR SODESMEA
DAY FEED AMOUNT
1 1/2 FEED 2 NONE3 NONE4 1/2 FEED5 FULL FEED
- On days with half feeding, all birds must be allowed to have access to the feed tomaintain good uniformity. Thus, it is advised to give all the feed at one time (ifpossible, at night, with the lights off).
- The 5 day program for SODESMEA includes 3 days with NO FEED. The rest ofthe program is the same.
- The 3 day program for SODESMEA includes only one day with NO FEED. Therest of the program is the same.
-
LIGHT INTENSITY AND RED LIGHT IMPORTANCE ON LIVABILITY
Understanding the light intensity management and the Use of red light help to optimize livability, feed conversion, and strengthen shell quality.
Light intensity must be high in growing (15 20 lux) and quite low in production (5 lux). Light intensity must be reduced no later than 10/14 days after birds have been housed. later than 10/14 days after birds have been housed.
A very low light intensity in the laying house ( 5 lux ) as well as the installation of red light at housing or shortly after (less than 10/14 days ) help reduce mortality by as much as 50%.....and is strongly advised for the SHAVER WHITE.

Calcium and Available Phosphorus feedingGROWING PERIOD
-with proper calcium ( 1 % minimum) and available phosphorus (0.45-0.5 %) feeding in growing
PRELAY PERIOD- through feeding a prelay feed with at least 2-2.5%
calcium ( prelay or layer feed ).
- The prelay feed rich in calcium must be given at least 2 weeks ( 14 days) before first eggs toleast 2 weeks ( 14 days) before first eggs tomaximize the calcium reserves in the bonesand optimize shell quality (16 18 weeks)
LAYING PERIOD
- use 4 to 4.5% calcium level in layer feed- Use higher available phosphorus levels until 40/45 weeks old
and then reduce available phosphorus in layer 2 feed - Use Midnight feeding program after the maximum hours of light
is achieved

MIDNIGHT FEEDING
1.
INSTALL NO LATER THAN ONE WEEK AFTER TRANSFER
2. MIDNIGHT FEEDING PERIOD OF 2 HOURS. THIS WILL ALLOW ALL BIRDS THEOPPORTUNITY TO EAT, NOT JUST DOMINANT BIRDS.

4. FEEDERS SHOULD RUN DURING THE BEGINNING PORTION OF THE M.N.F. IN ORDER TOSTIMULATE BIRDS TO EAT.
AFTER 1 WEEK OF USING M.N.F., THE CONSUMPTION RATE WILL STABILIZE. M.N.F. WILLNOT LEAD TO INCREASES IN AVERAGE CONSUMPTION RATES GIVEN NORMALCONDITIONS, I.E., TEMPERATURE. HOWEVER IT IS VERY USEFUL TO INCREASECONSUMPTION DURING EXTREME HEAT.
