Clover silage made from a special use in organic poultry feed (layers, broilers, clover grass silage, outlet, feeding intensity, use recommendations for the practical feeding)
Project
Project code: 2811OE022
Contract period: 01.10.2011
- 31.05.2015
Budget: 141,691 Euro
Purpose of research: Applied research
Aim: a) to realize 100% organic feedstuffs in diets for poultry b) to increase the use of regional produced feed, c) to improve animal welfare d) to know effects on product quality, e) to reduce feeding costs.
Methods:
1. working-step: Evaluation of different clover grass mixtures, harvested in different stages of maturation and ensilaged in different processes.
2. working-step: Two on-station feeding trials with laying hens are performed. The aim is to evaluate the effect of special clover grass silage (sCGS) in diets on feed intake, performance, egg quality and welfare aspects (feeding behaviour, general activity) in laying hens. Each study includes two dietary treatments (sCGS vs. Non-sCGS) and will be performed during the laying period. The first study will running in the autumn-winter time (outdoor access lim-ited, no forage), while the second study will running in the spring-summer time (outdoor ac-cess, covered with forage). Main parameters include data on feeding value (e.g. energy and essential amino acid contents), performance (e.g. live weight, egg yield, feed consumption, feed conversion rate) and product quality (egg, fatty acids).
3. working-step: One on-station feeding trial with broilers is performed. The aim is to evaluate the effect of sCGS in diets on feed consumption, performance, product quality and welfare aspects (feeding behaviour, general activity and aggression level) in slower growing broiler genotypes. The study includes 2 x 2 treatments (sCGS vs. Non-sCGS and outdoor access, covered with forage vs outdoor access without forage) and will be performed during the fat-tening period (56 days). The study will running in the summer time. Main parameters include data on feeding value (e.g. energy and essential amino acid contents), performance (e.g. live weight, feed consumption, feed conversion rate) and product quality (meat, meat colour, fatty acids).
Expected results: The project delivers practical guidelines to feed additional organic roughage to poultry (publishable report) including process engineering (CGS).
