groups — one group received the Salmonella Typhimuri- um LPS inoculum and the other group was administered saline. Within each group there was a set of layers that served as the control and did not receive any added zinc in the diet, a set of layers received 60 ppm of inorganic zinc sulphate in the diet and a final set of layers received 60 ppm of Availa-Zn in the diet. The study showed that the layers fed zinc from Availa-Zn had a greater cytokine con- centration at 3-hours post inoculation (Table 1) simultane- ously the rectal temperature in the layers inoculated with the Salmonella Typhimurium LPS challenge peaked earlier, demonstrating a more rapid immune response. In addi- tion, the layers fed Availa-Zn had a lower cytokine concen- tration at 12-hours post inoculation, and the rectal tem- perature in the layers returned to an inflammatory neutral state more rapidly. By providing zinc from Availa-Zn, the fever response process was initiated more rapidly, and the fever subsided sooner, illustrating a more efficient im- mune response that minimises the energy expenditure as- sociated with systemic infection.
Quick recovery after challenge By including zinc from Availa-Zn in the diet, the producer is equipping the layer or broiler to be able to more quickly re- cover from a challenge. And in doing so, the bird returns to a normal state of production and more rapidly funnels nu- trients to animal performance including growth and egg production. At the end of the day, when producers include zinc from Availa-Zn in the poultry diet, they are helping enhance the overall wellness and performance of the layers and broilers in their operation, while also delivering a strong return on investment.
By including zinc from Availa-Zn in the diet, the producer is equipping the layer or broiler to more quickly recover from a challenge.
