Common managerial Practices for Layers

a) Litter management:

• Cover the floor with 4 inches of dry litter.
• More litter is added at frequent interval until the litter is 6-10 inch deep.
• Should be done prior to cold weather.
• Litter should be stirred frequently during winter.
• Change the litter during spring season.
• Put 25 lbs of hydrated lime per 100 sq ft. floor space when litter is 4 inch deep.

b) Transfer of pullet to laying house:

• Thoroughly cleaned and disinfected before transferring the pullet.
• Move the pullet with little disturbance as possible.
• Prefer “All-in-all-out” system.

Advantages of  “All-in-all-out” system.

• Farm has birds of only one age group.
• Decrease stress, control disease and reduce mortality by 4%.
• Rate of lay increased by 5%.

c) Placing of laying nest:

• Nest box is placed at least one month before the start of lay.
• To encourage the birds to lay eggs in boxes.

d) Light during laying period:

• Light affects the secretion of gonadotrophic hormone which influence reproductive behavior of birds.
• It also affects age of sexual maturity and rate of egg production.
• Light should be made available enough to read newspaper.

e) House temperature and ventilation control:

• 45⁰C is desirable.
• Air forced circulation heating system is preferable in large room containing 1000 or more birds.
• Careful attention must be given during cold seasons to the adjustment of curtains, windows and ventilators.
• Install electrically operating fan to adjust fresh air or in removing CO₂.

f) Humidity:

• Influences the health and egg production of the layer.
• Should be about 50%.

g) Nutrient requirement:

• Supply adequate energy, protein, mineral and vitamins.

h) Space requirement:

• As recommended.
