Cracking the code to longevity: The revolution of long-life layer production

The egg industry is undergoing significant transformations, setting ambitious targets for production efficiency and sustainability. Recent outbreaks of avian influenza have led to a reduction in the number of hens, further challenging the industry to enhance its efficiency and sustainability. The ability to produce 500 eggs over 100 weeks requires holistic considerations, and nutritional support…

Optimal gilt management ensures optimal lifetime performance

Sows serve as integral components within the dynamic framework of a piggery. Their pivotal role involves the proficient and precise generation of the next cohort of porkers or breeding animals. This process is executed through a nuanced understanding of porcine biology, effectively incorporating scientific principles into breeding practices to ensure optimal lifetime performance. The role…

Solutions to supporting the long-life layer

It is well known that avian influenza (AI) has been particularly concerning this year, affecting many poultry producers from laying hens to breeder operations. This has led to a limited supply of point-of-lay hens and, consequently, hens that are still in production will need to be pushed to produce eggs for longer than the normal…

Don’t be a Humpty Dumpty when it comes to eggshell quality

It is a chicken-and-egg situation when it comes to reaching the 100-week production milestone without layer health and eggshell quality coming across one’s mind. Eggshells are formed through the deposition of calcium carbonate (CaCO3), which is mainly obtained as a source of limestone from the diet, or through depletion of calcium from skeletal bone when…

The rocky relationship between limestone solubility and phytase efficacy

poultry

It is well known that limestone is used as a major source of inorganic calcium (Ca) in commercial poultry diets, as well as microbial phytase to improve phosphorus (P) and Ca utilisation, and to reduce P excretion into the environment.  The efficacy of commercial microbial phytase to degrade phytate (myo-inositol hexakisphosphate, or IP6) in the…

The benefits of measuring calcium digestibility from raw materials in poultry

limestone variation

Abstract To date, poultry diets have been formulated to meet estimated requirements for total calcium (Ca), while frequently also maintaining a specified ratio of total Ca to available phosphorus (AvP). In vegetable-based diets, limestone can contribute in excess of 50% and 90% of dietary Ca in broiler and layer diets, respectively. In laying hens, it…
