Dramatic decrease in the number of dirty eggs due to improved intestinal health
15 July 2016
A field trial in Indonesia with 10,000 broiler breeders concluded that using a feed additive in the drinking water resulted in significantly less eggs contamination, potentially leading to more sellable chicks.
Broiler breeders are valuable animals which are under high pressure for optimal production. The main goal of broiler breeder producers is to obtain as many good- quality, fertile eggs and hatched broiler chicks as possible. This stress might suppress the health status of the birds, leading to a decreased performance.
In order to help solve this challenge, Trouw Nutrition performed a trial in Indonesia. The study aimed to asses if applying a liquid feed additive in the drinking water could support the intestinal health status of these animals, thereby helping them to maintain optimal production levels.
Intestinal health and eggs contamination
An optimal intestinal health status in broiler breeders is important for reducing contamination of hatching eggs. The reason for this is that by improving breeders’ gut health the number of dirty eggs should consequently decrease. Cleaner eggs might lead to a higher number of sellable chicks.
A field trial to test results
Trouw Nutrition conducted a field trial in Indonesia with 10,000 Lohman broiler breeders. The birds, kept in a closed housing system, showed intestinal health issues before the start of the study. During 4 weeks a feed additive by Selko was applied in drinking water at 1l/ 1000l. Among other parameters, gut health and number of dirty eggs before and during the additive consumption were compared.
At the end of the study the gut health of the birds improved to optimal score, which dramatically reduced the number of dirty eggs per day. This obviously impacted the cumulative number of dirty eggs during the production phase as well.
In a study by the University of Arkansas it was found that the level of dirty eggs can have an impact of hatch loss up to 20%.
“The results we obtained by applying the Selko feed additive might lead to an increase of hatchable eggs, which would result in more sellable chicks” said Anet van de Wouw , Global Product Manager at Selko Feed Additives.
Selko-pH is a liquid feed additive. Its positive effect on performance is achieved in 3 steps: effectively reducing water pH, supporting digestion and improving microbial balance.
A healthy microbial balance is crucial for optimal feed utilisation and animal performance.
