2 Introduction This booklet contains the performance objectives for the Lohmann Meat broiler chicken to be used with the L.I.R. Broiler Management Programme. The performance objectives represent production achievable under good management and environmental conditions, and when feeding recommended nutrient levels. The figures included represent the top % world wide flocks. Average performance may be 10 to % lower. Monitoring of performance within a broiler production operation gives the opportunity to identify areas for improvement. The performance objectives should be used to indicate the genetic potential of the Lohmann Meat broiler. Continuous increase in performance results from the combination of genetic, management, nutritional and veterinary improvements. Genetic selection in Aviagen s pedigree programmes aims to deliver balanced improvement in liveweight, FCR and liveability. The components of yield will vary among processing plants depending on type of equipment used and the exact portions being produced. For further information on managing Lohmann Meat broilers, please consult your local Technical Service Manager. 1

3 Cost effective production of chicken meat depends on achieving good bird performance. The following points are important to achieve optimum performance of the Lohmann Meat broiler. 6 Key Points for better Broiler performance: Maximise day old broiler chick quality by good management of hatching, storage and transport conditions. Ensure that both house and floor temperatures are adequate before, during and after chicks arrival; monitor chick behaviour. Prior to chick arrival, set up the brooding areas with plenty of supplementary feeders and drinkers. Ensure that the chicks have easy access to these. Achieve a first week bodyweight of 1 grams or greater by good management. This will maximise growth and improve flock uniformity. Plan and manage stocking density according to the house design (open or closed). The physical quality of the feed should not be that of mash or include a high proportion of fines. Feed a good crumb/crumble as the starter ration. The crumb size should gradually increase to a short/longer pellet as the bird develops. 2

7 Lohmann Meat Broiler Carcase Yield The following tables indicate how yields of the major portions change with increasing liveweight in each sex. Eviscerated yield is broken down into breast meat, thigh and drumstick to represent a portioning operation. TABLE 4 Lohmann Meat Male - Portion Breast % Thigh % Drumstick % Evis % Liveweight (kg) TABLE 5 Lohmann Meat Female - Portion Breast % Thigh % Drumstick % Evis % Liveweight (kg) Definitions of Terms: Eviscerated %: eviscerated carcase, without neck, abdominal fat & internal organs, as a percentage of liveweight. Total Meat %: sum of breast meat, thigh deboned without skin and drumstick deboned without skin as a percentage of liveweight. Breast %: breast meat without skin and bone removed, as a percentage of liveweight. Thigh/Drumstick %: whole thigh/drumstick with skin and bone in, as a percentage of liveweight. sum of deboned thigh without skin and deboned drumstick Leg Meat %: without skin as a percentage of liveweight. 6
