BROILER BREEDER MANAGEMENTGrowing/Rearing Laying
Rearing/Growing (8-24 weeks) Broiler Parent: GGP Male line Female line A B C D WCXWC WCXWC WPRXWPR WPRXWPR M F M F M F M F GP AB CD WCXWC WPRXWPR M F M F PARENTS WC X WPR M F BROILER Male & Female chicks (Hybrid).
(a) Sexes reared separately. Males & females reared separately until 21 weeks then mixed with ratio of 12 :100(12%). At sexual maturity (24 weeks) reduce No. of males to 10/ 100 (10%).
(b) Sexes intermingled. Sexes reared separately for first 2 weeks, beak trimmed & then mixed in equal numbers.
SPACE PER BIRD(9-24 weeks)
Floor space(Sq. feet)Drinker space (linear inch)Feeder space (linear inchFemale1.50-2.501.06.0Male2.0-3.01.258.0
Target Weight (23wks) Male = 3Kg Female = 2.5 Kg
To achieve target weight. A measured quantity of feed each day to meet body weight target. Quantitative Feed Restriction.Quantity of recommended feed is restricted up to10 to 20%.
Qualitative Feed Restriction
Feeding of low energy & low protein Under Weight Birds. Increase quantity or quality of feed.Over Weight Birds. Weekly feed increase is stopped.
Nutrient Requirement Calcium (%) =1.0 Additional supplementation of vitamins &mineralsBreeder Grower Ration. Energy = 2700Kcal/Kg CP= 15% Grit Feeding= 500gm small sized grit /100 birds / week.
Light Management. Light duration = 8-12 H Light intensity = 0.5 foot candle. Never increase duration or intensity of light during growing. Grow birds on constant or decreasing day length & lowered intensity.
Body Weight Control
Objectives: (1) Uniform body weight. (2) Small frame size. (3) Uniformly fleshed
90% birds be in weight class, plus/ minus 10% of the average weight of flock.
Key Factors For Uniformity
From 2 weeks onward, weekly weigh 5% of birds.Regular grading & separating of birds according to their weight. Sufficient feeding & drinking space.
Cont.Fast feed distribution to all birds in the house. Adequate floor space & uniform environment. Uniform beak trimming. Proper litter management.
PRODUCTION MANAGEMENT (24-64 weeks)
Production starts = 24 Peak Production = 32 Peak Production period = 2-3 Decline Production = 38-39
At 64 weeks = un- economical production Total eggs /hen =164 Hatchability (%) = 85 Total chicks/hen =140
PRODUCTION MANAGEMENT (24-64 weeks)
Floor space/ bird = 3-3.50 sq.ft Feeder space Trough = 6 inch/ bird Tube (diameter) = 36cm Birds /trough = 11 Water space = 1.25 inch /bird. No. of birds /drinker = 15
One nest for = Every 4 hens.Height = 35cmDepth = 35 cmWidth = 30.5 cm
FEEDING MANAGEMENTFixed quantity of feed according to flock condition & rate of egg production.
(a)Pre Laying Period (22-24 weeks)Some what high protein & energy.
(b) During Production
(26 week to peak production ) At start of production increase feed weekly. At 30% production full feeding to hens. Do not reduce during this period. Extra vitamins.
Factors Affecting FCR
(I) Feed quality.
(II) Environmental temperature. At low temperature increase amount of feed.
In summer layers reduce feed intake, increase energy, vitamins, amino acids & minerals.
(c) After Peak Production
Feed quantity for hens be reduced by 1-2 gm / week. Decrease in production 4-5%, start decreasing feed 2-2.5 gm/bird / week. If there is some negative effect on peak production due to decreased feed, return to pre-existing feed level. Feed reduction be gradual, not abrupt, keeping in mind production, body weight & weather.
Controlled FeedingTo maintain body weight targets.Advantages: (I) Uniform body weight. (II) First eggs are larger. (III) High egg production. (IV) Less mortality rate. (V) Increased egg size, fertility & hatchability. (VI) Reduced feed cost.
LIGHT MANAGEMENTDuration. Never decrease light during production. 16-17 H light.Light intensity 1.0 foot candle / bird. Do not decrease light intensity during production.Sex Ratio. Male to female ratio 1: 10. Maintain extra male separately.
