Pre-laying management of PS

Pre-laying management of PS

Key points of Pre-laying management (19-23 wks):

  • Supply pre-breeder ration
  • Start lighting program
  • At 21 wks. Distance between pubic bone 2 cm (.75 inches)
  • Check the flashing level ( U shape), muscle development in radius and ulna)
  • Male mixing
  • Laying box set up.
  • Check maturity level.
  • Fleshing level (V, U shape distance between pubic bone, feather, dropping.
  • Redness of comb, wattle, eye ring, Brighten of an eye.
  • Moister of the vent.
  • Pre-Laying feed supply.
  • Male maturation symptom (Call)
  • Observation shank length, comb, tail, neck, back.

The management of pre- laying period includes-

 

  1. A) To achieve good uniformity.
  2. B) To achieve proper body weight with uniformity.
  3. C) To provide pre-breeder feed.
  4. D) To provide lighting program.
  5. E) To mix the best male with female.
  1. A) Good uniformity:

The potentiality of parent stock birds depends on good uniformity. Higher the uniformity higher the production. The following multiplier play an important role in achieving and maintaining good uniformity-

  1. Health status of the flock.
  2. Access to feed and water.
  3. Water restriction should not be too severe.
  4. Feed consumption time.

 

  1. B) Body Weight:

Standard body wt. of HC birds as follows-

 Age (wks.)             Body wt. (g)

                          Close ….…..Open

19                       2050………..2120

20                       2180………..2260

21                       2330………..2420

22                       2480………..2580

23                       2630………..2740

24                       2780………..2900

  1. C) Pre-breeder feed:

The difference between grower & pre-breeder feed mentioned below:

Nutrients  Grower    Pre-breeder  Unit

ME           2700       2830       Kcal/kg

CP            14.50      15.50      %

Calcium     0.95        1.28       %

    1. D) Check the sexual maturity:

 

Age in week Primary feather Present

(Nos.)

Primary feather Drop

(Nos.)

09 9.0 01
10 8.5 1.5
11 8.0 2.0
12 7.5 2.5
13 6.5 3.5
14 5.5 4.5
15 5.0 5.0
16 4.0 6.0
17 3.5 6.5
18 3.3 6.7
19 3.0 7.0
20 2.5 7.5
21 2.0 8.0

 

    1. E) Lighting Program:

 

This program mentioned below:

Age                 Duration (H)             Intensity (L)

Days         Wks.

1-14         1-2           24 to 9*                      60

15-140     3-20            8                               5

141-147   21              10                              60

148-154   22              11                              60

155-161   23              12                              60

162-168   24              13                              60

169-175   25              14                              60

176-182   26              15                              60

183-189   27              15.30                         60

190-cull   28               16                             60

*Gradual decrease from 24 hours to 9 hours. This program for dark rearing house.

  1. F) Mixing of Male:

At 23rd wks. of age 2% good male should be mixed with the female. Then after 5% , 30% & 50% production another 2% , 3% & 1% male should be mixed respectively.

The males should be selected on following points:

  1. The selected males should have strong and straight legs with good toes, joints and keels should be free from any defects.
  2. The selected males should have good, straight and long keel bone with good conformation and fleshing.
  3. The selected males should have a good masculine appearance with bright eyes, comb, wattle and strong well-aligned beaks.
