Patio BROODING FOR ROBUSTNESS Lotte van de Ven Research & Development, Vencomatic Adaptation Physiology Group, Wageningen University Patio • • • Background Patio: the concept Brooding for Robustness Hatchery Farmer Current hatchery practice Current hatchery practice • Removal of chicks from the hatcher after 21 days 12 hours • Chicks hatch over a time window of 24-40 hours Study of Tona et al., 2003 using Cobb eggs Current hatchery practice A broiler spents the first 5% of its’ life before placement in the farm Current hatchery practice effects of climate • Suboptimal post hatch growth Leksrisompong et al., 2009. North Caroline State University, USA. Poultry Science 88:1321-1329. Current hatchery practice effects of delayed feed access • Up to 8% weight loss in 24 hours Study of Careghi et al., 2005 using Cobb eggs. Poultry Science 84:1314-1320 Current hatchery practice effects of delayed feed access • Suboptimal development of immune system Study of Dibner et al., 1998, using broiler chicks. Journal of Applied Poultry Science 7:425-436 Current hatchery practice effects of delayed feed access • Suboptimal development of digestive system Study of Bigot et al., 2003. Poultry Science 82:781-788. Current hatchery practice effects of delayed feed access • Suboptimal ability to control body temperature Study of Van den Brand et al., 2010 using Hybro chicks. Poultry Science 89:716-720 The brooding phase decisive to later performance Current broiler production climate & litter control • Suboptimal climate effectiveness Current broiler production antibiotics • Risk for drug resistance Current broiler production labor Placement of day olds Manual harvesting: • Labor requirements 10,000 broilers / person = 25,000 kg / person / shift Dust, ammonia, night work Broiler production future challenges Energy Climate control Qualified personnel Land Infectious diseases Delayed feed access Genetics Animal welfare Overheating Use of antibiotics Patio, the concept Patio the concept Objective: To produce robust broilers in a sustainable way Robustness “capacity to withstand stresses, pressures, or changes in circumstances” Patio the concept Objective: Produce healthy broilers in a sustainable way How? 1. Controlled environment at bird level, from the moment of hatching 2. Less dependent from external factors: climate, labour, resources Patio, the concept Combine hatching & brooding Hatchery Patio system Incubation d 1-18 Incubation d 1-18 Transfer & candling Transfer & candling Hatching of chicks d 18-21 Transport of eggs to broiler house Transport to broiler house Hatching of chicks d 18-21 Patio, the concept Combine hatching & brooding Patio, the concept Combine hatching & brooding Patio, the concept multiple levels 1.
