A PRACTICAL GEL DELIVERY SYSTEM FOR POULTRY HATCHERIES
Gel-Pac®
Edible Gel Delivery for Poultry Vaccines and Oral Additives
Gel-Pac® from Animal Science Products is a powdered, edible gel concentrate designed for delivering vaccines and oral additives to newly hatched poultry using hatchery tap water.
When mixed with water, Gel-Pac forms soft gel droplets that carry selected vaccines and other oral additives. The droplets are applied to hatchlings and consumed through natural preening behavior.
Gel-Pac has been evaluated for coccidiosis vaccine delivery, infectious bronchitis virus (IBV) vaccination, and combined vaccine applications.

How Gel-Pac Works
Gel-Pac is prepared as an edible gel suspension, applied to newly hatched chicks, and consumed through natural preening behavior.
1. Prepare the Gel
Mix Gel-Pac powdered concentrate with water to form an edible gel suspension. Add selected vaccines or oral additives according to the applicable instructions.
2. Apply Gel Droplets
Use suitable hatchery gel application equipment to distribute the prepared gel droplets onto newly hatched chicks.
3. Natural Preening
Chicks consume the edible gel droplets through natural preening behavior, delivering the incorporated vaccines or oral additives.
Gel-Pac Applications & Research
Coccidiosis Vaccine Suspension Uniformity
Uniform distribution of coccidiosis vaccine oocysts is an important consideration during hatchery vaccination.
In the 2023 Jordan–Izard study, researchers compared the distribution of coccidiosis vaccine oocysts suspended in Gel-Pac with oocysts suspended in water without agitation.
The researchers observed that oocysts in the undisturbed water suspension settled toward the bottom of the container, while the Gel-Pac suspension maintained a more uniform distribution during the two-hour observation period.

Research finding: In the Jordan–Izard study, coccidiosis vaccine oocysts suspended in water settled rapidly when agitation stopped. In contrast, the Gel-Pac suspension maintained a more uniform distribution across the top, middle, and bottom portions of the container during the two-hour observation period.

Combined Coccidiosis and IBV Vaccine Delivery
The 2023 Jordan–Izard study also evaluated Gel-Pac as a delivery medium for infectious bronchitis virus (IBV) vaccine, administered alone or in combination with coccidiosis vaccine.
Researchers found that Gel-Pac maintained IBV vaccine stability under the conditions tested. When the specific IBV and coccidiosis vaccines used in the study were combined in Gel-Pac, the researchers observed successful vaccine uptake and replication.
The study concluded that Gel-Pac could support combined delivery of these vaccines when mixing and application were performed correctly.
These findings apply to the vaccine formulations and experimental conditions evaluated in the study.
