BreederCobb 700Ten years of research to develop Cobb 700The Cobb 700 has been introduced to meet theincreasing demand not just for more breast meat,but for breast meat produced at the lowest cost.The need to develop a new type of product devoted tomaximum meat yield at high broiler weights wasidentified in the early 1990s. Meat yield would be the target,but the chicken must alsocarry the Cobb trade marksof outstanding broilerfeed conversion, excellentlivability and low cost ofproduction.The development duringmore than ten years hasinvolved starting newlines, new selectionmethods and a new set ofbreeding goals. It hasbenefited from Cobb’sincreasing investment inresearch during thisperiod, totalling morethan $200 million and reflecting the value which the parentcompany, Tyson Foods Inc, places on breed development.Families from the highest-yielding Cobb lines were chosento begin new synthetic lines which were placed on an annualreproduction program on one of the state-of-the-art pedigreefarms.Age at depletion (weeks) 60 65(days) 420 455Age at 5% production (weeks) 24 24(days) 168 168Total eggs/hen housed 155.2 170.3Hatching eggs/hen housed (50g minimum) 149.7 164.3Peak hatchability (%) 91 91Average hatchability (%) 86 85Broiler chicks/hen housed 128.4 139.8Livability from day-old to depletion (%) 92 91Global Cobb 700 Performance (to 65 weeks)Top 3 flocks by Total EggsTarget 170.3Flock A 174.1Flock B 171.3Flock C 170.4Top 3 flocks by % HatchTarget 85.00Flock G 85.60Flock H 85.60Flock I 85.50Breeder PerformanceTop 3 flocks by Hatching EggsTarget 164.3Flock D 168.7Flock E 163.3Flock F 162.6Top 3 flocks by ChicksTarget 139.8Flock J 136.7Flock K 136.6Flock L 132.9New innovations in genetics and in management wereneeded. Floor area, for example, was increased to giveindividual birds more room to grow to heavier weights,and feeding programs were adjusted to encourage eggproduction.Egg numbers, egg quality, fertility, hatchability, livabilityand chick quality information on each hen and her offspringwere added to a growing genetic database. Computerprograms were enhanced to improve breeding valueestimation for all valuable traits for each individual and topermit selection of birds with the optimum combination ofeach trait.Even with selection pressures aimed at increased meatyield, the breeder is achieving competitive production levels.Cobb 700 parent stock became available in 2001 and hasbeen supplied to customers worldwide.
Broiler Cobb 700 and YieldLowest cost total deboned meatThe Cobb 700 is a unique product geneticallydesigned for the high meat yield, deboningmarket and capable of maximizing profits fromprocessing.In developing the Cobb 700geneticists have achievedvery similar growth ratesand feed conversions to theCobb 500. Field livability isexcellent even at large birdweights.Most important of all, breastmeat yield of the Cobb 700broiler is a full one percenthigher and this extra yield isachieved at the industry’slowest cost of production forthis type of chicken.The good health andvitality of the broiler,reflected in leg strength and good early skeletaldevelopment is the result of 20 years of research techniquespioneered by Cobb. Since 1989 Cobb geneticists havebeen using oximeters for measuring blood oxygensaturation to assess the physiological health of individualbirds and pedigree lines. Ultra-sound and other bodyimaging technologies have been developed specificallyto study bone andmuscle development inchickens.Genetic markers and DNA profiling are used to verify thepresence of individual genes, providing a new level ofprecision in selection and advancing the pace of progress.Above all, the emphasis is placed on selecting birds fromfamilies that exhibit outstanding health traits - excellentlivability, strong legs and skeletal frame, resistance toascites, high overall immune response and good feathercover.Number of birds per weightNumber of birds per weight27262524232221201918171615141312111098765432102726252423222120191817161514131211109876543210Broiler Uniformity ComparisonCompetitor4.04.14.24.34.44.54.64.74.84.95.05.15.25.35.45.55.65.75.85.96.06.16.26.36.46.56.66.76.86.97.07.17.27.37.47.57.67.77.87.98.08.1Body weight (lb)Cobb 7004.04.14.24.34.44.54.64.74.84.95.05.15.25.35.45.55.65.75.85.96.06.16.26.36.46.56.66.76.86.97.07.17.27.37.47.57.67.77.87.98.08.1Body weight (lb)Average weight5.95lb/2.69kgCV 12.64Uniformity 56.30%Average weight6.02lb/2.73kgCV 11.05Uniformity 62.07%
