I have been thinking about my results that I posted yesterday. because it seems like it is almost a 1:1 feed conversion which I think is misleading.
I think the chicks arrives severely dehydrated and a good portion of that weight gain is due to re-hydration after weighing.
And one of the things I was thinking about as I weighed the chicks after 5 days of feed and 7 days since hatch, is the broiler feed chart assumes that feed and water is given on day 1 of hatch. After all the chart was made for and by major broiler producers. So they are offered feed and water from day 1. And I know from hatching my own chicks that even though they don't need to, they will eat and drink within hours of hatching as I have observed it. So while a good guide to see how you compare to the major producers, it is flawed for the smaller producer that has to have chicks shipped in so you don't even receive them until they are post hatch by 2 -3 days.
the research I have been doing states that the first 7 days in a meat chicks life is critical for the long term end weight being produced. That while genetically they can reach such and such a weight, if during the first 7 days not the correct nutrition and supplements being given can cause them to never being able to reach their genetic possible weight. And since the study was geared towards big meat producers, only went through 60 days. So it once again brings into doubt if it is truly true. on the one hand from a big broiler producer it is, on the other from the small producer that wants to raise meat for their family, it might not be as we can be more patient and give them more time to bring their weight up to an acceptable weight for harvest.
Now, I'm rambling as I have been up since 1 am when the storm blew through and woke me up.
