A specification for a male diet is provided in this booklet. It may be beneficial to use a separate male diet during the production period. The values for amino acid digestibility are on Standardized Ileal Digestibility (SID) assays. The energy values used in these specifications are on assays for Metabolizable Energy published by the World s Poultry Science Association (WPSA). Feed allocation should be determined by body weight and egg production levels, and therefore altered to maintain the recommended weight and egg production profiles. Adjustment of nutrient levels must be made to reflect the ing of different energy levels. Please note, these nutrient recommendations are on the specified energy levels. ![]() 4-Stage Rearing Program - where a lower nutrient density and a higher volume ing strategy is required. 3-Stage Rearing Program - where a Pre-Breeder diet is introduced to prepare the birds for the laying period. Included in this booklet are 3 different rearing programs applicable for the following situations: 2-Stage Rearing Program - where the same energy density is used during rear. For the nutritional recommendations that follow, nutrient specifications presented have been upon daily energy allocations that enable body-weight profiles to be achieved. Performance To achieve optimal reproductive performance, it is important that the body-weight profiles recommended in the Ross 308 Parent Stock Performance Objectives are followed. 1 1 PARENT STOCK ROSS 308 Nutrition Specifications An Aviagen BrandĢ Introduction This booklet contains the nutritional recommendations for Ross 308 (slow feathering) parent stock and is to be used with the Ross Parent Stock Management Handbook and the Ross 308 Parent Stock Performance Objectives.
