LATIN AMERICA BROILER ROSS 408 Performance Objectives An Aviagen Brand

Introduction This booklet contains the performance objectives for the Ross 408 Broiler and is to be used with the Ross Broiler Management Handbook. Performance Poultry production is a global activity but across the world there are differing management strategies adapted to local conditions. These performance objectives are specifically for poultry producers in Latin America. The advice provided is therefore relevant to the management strategies employed within the Latin American region. However, the recommendations given are useful and informative for other world regions. These objectives indicate the performance achievable under good management and environmental conditions and when feeding nutrient levels described in the Ross 408 Broiler Nutrition Specifications. Producers may find that local factors prevent such performance from 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. The objectives are presented in two sections to reflect the global nature of the publication. g lb contains the performance data in metric measurement and contains imperial measurements. In the tables, 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. For further information on the management of Ross stock, please contact your local Ross representative. 1

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 Ross 408 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 21ºC (69.8ºF) from 21 days onwards may improve growth rates. Maintain high standards of biosecurity and cleanliness to keep disease to a minimum. 2

Carcass Yield The following diagrams indicate how yields of the major portions change with increasing live weight in each sex. Two types of processing are described: eviscerated yield is broken down into breast meat, thigh, drumstick and wing to represent a portioning operation and into breast meat and leg meat to represent a deboning operation.
