00:00These chickens are robust, possibly more robust than your average bird.
00:08What makes them so is years of research.
00:13The Queensland Alliance for Agriculture and Food Innovation Research Institute
00:17is part of a consortium that, for the past five years,
00:21has been looking at the nutrition of hens and broiler breeders.
00:25Professor Eugenie Rorra is heading up the project.
00:31We're looking at mother-hand nutrition.
00:36We want to understand how we can improve that nutrition of the parental generation
00:42and how that has an impact on the broiler progeny,
00:48the broilers that ultimately will be grown for me.
00:55The aim of the project is to see if, by changing the nutrition of the mother hens,
01:03will it make a transgenerational step and increase the robustness of day-old chicks.
01:11So why are they interested?
01:12The one-day-old chick, the chick that has just hatched,
01:17that is the most vulnerable of their lifetime.
01:22So we want that chick to be as robust as possible,
01:26good development of the immune system, of the digestive system,
01:31because they have to endure at that hatching time,
01:35they have to endure a very harsh environment sometimes.
01:38The environment refers to the natural life cycle of the chicks.
01:45Changing from a yolk-based, liquid-based diet to solid feed,
01:48that transition can be harsh for the chicks.
01:52The hatching of the egg exposes the animal to the external environment,
01:56introducing potential bacteria and pathogens,
01:58with chicks most vulnerable to infections such as E. coli.
02:02The percentage of deaths can vary a lot between farms.
02:07Management and hygiene practices help determine the final incidence.
02:12But it is low.
02:14There's a mortality rate below 1% in the first week
02:17in modern commercial production systems.
02:20So there's a number of big steps for a baby chick of 45 to 50 grams to endure,
02:25and to have a good start on their life.
02:28The genetics of the broiler chickens together with the optimised practices
02:34that we see in commercial practice,
02:36that's what makes the industry so successful, in my view.
02:40that's what makes the big difference.
