Getting the most out of the modern laying hen Joshua de Kock – Technical Advisor: Monogastric Modern layer hens can lay at least 450 eggs during their productive lifespan, with some breeds producing over 500 eggs by 100 weeks of age. However, this number is not guaranteed, as many factors can influence egg production. Feed quality, housing conditions, disease, and stocking density are some of themajor factors that affect the productive capabilities of a laying hen. While some of these factors are easier to control than others, it is important to weigh the risks associated with these factors. As much information as possible needs to be collected to compare and draw conclusions to accurately determine the role that all these factors play in production. On farm feed quality factors Feed is the highest cost on a layer farm, and it’s often where producers look to cut expenses. However, poor-quality feed can affect hens for the rest of their productive lifespan, as factors such as mycotoxins may cause irreparable damage to their organs. While the inclusion of a mycotoxin binder might seem like just an additional expense contributing to the overall feed cost, it is a necessary investment not only to maintain current egg production, but also to extend the productive lifespan of the laying hen. To ensure that feed quality is not compromised, it needs to be stored in a dry and cool area to prevent spoilage. The largest contributing factor to feed spoilage is moisture, and while keeping feed in an enclosed area does help, moisture can often seep into the feed from the floor. Feed should therefore be stored off the ground, which can be accomplished by simply placing a pallet beneath bagged feed or in a silo for bulk feed.
