Spiking Program Design
When it comes to spiking, it’s important to be proactive. Do not wait for hatchability to decline to establish a program; at that point it is too late. The best results are typically achieved if spiking is done prior to a reduction in fertility.
Spiking can be part of a grower’s regular, scheduled management procedures. Spiking once in the life of the flock is typically enough; however, flocks spiked twice on an eight to 10 week interval also show good results. Spiking is usually not economical beyond 55 weeks of age.
