BROILER YIELD PLUS x ROSS 708 Performance Objectives An Aviagen Brand An Aviagen Brand
Introduction This booklet contains the performance objectives for the Yield Plus TM x Ross 708 Broiler and is to be used with the Ross Broiler Management Handbook. Performance These objectives indicate the performance achievable under good management and environmental conditions and when feeding nutrient levels described in the Ross 708 Broiler Nutrition Specifications. Producers may find that local factors prevent such performance being achieved. For example: The availability of raw materials may limit nutrient content and intake. Extreme climatic conditions will reduce performance. Economic considerations may limit choice of production systems. Therefore, average performance may be lower than the figures presented here. The objectives are presented in two sections to reflect the global nature of the publication. Section Section g lb contains the performance data in metric measurement and contains imperial measurements. In the tables the values are rounded, this may result in small inaccuracies when using the objectives to calculate other performance statistics. Yields will vary between processing plants depending on type of equipment used (e.g. carcass chilling technology, automated versus manual deboning) and the exact portion being produced. Every attempt has been made to ensure the accuracy and relevance of the information presented. However, Aviagen accepts no liability for the consequences of using the information for the management of chickens. For further information on the management of Ross stock, please contact your local Ross representative.

It is designed to satisfy the demands of customers who require consistency of performance and the versatility to meet a broad range of end product requirements. Cost effective production of chicken meat depends on achieving good bird performance and the following points are important for optimizing performance of the Yield Plus x Ross 708 broiler: Maximize chick quality by good management of hatching, storage and transport conditions. Design the brooding set-up to ensure easy access to water and feed at placement, and to ease the transition between supplementary systems and the automated feeders and drinkers at 4-5 days. Feed a highly digestible and nutritionally balanced Starter diet. Keep chicks in their thermal comfort zone by monitoring chick behavior, but beware of low relative humidities (less than 50% RH). Establish a minimum ventilation program from day one. Monitor crop fill, feeding and drinking behavior and 7-day live weight to allow continuous improvement of the brooding set-up. Keep birds in their thermal comfort zone throughout the growing period. Fast growing broilers produce large amounts of heat, particularly in the second half of the grow-out period. Keeping ambient temperatures less than 0C (69.80F) from days onwards may improve growth rates. Maintain high standards of biosecurity and cleanliness to keep disease to a minimum.
