We used 18% start to finish on our first batch of 100. At 53 days we harvested half and their dressed weights averaged 5lbs. We harvested the other half one week later at 60 days and their average dressed weights were 6.25lbs.
We got our second batch while the first batch was still growing out and I was second guessing my feed decision because I thought our cornish looked to be on the small side so for the second batch I started them on 20%. I bought a quarter ton and can't remember how long it took them to finish it... maybe 2.5 weeks. We then put them onto the 18%. At day 53 this batches average was 4lbs. There are other variables besides protein content that could have effected growth so I don't know why our second batch was so much smaller. What I do know is that we did fine with the 18% from start to finish and it was cheaper then if we did a higher protein from start to finish. As we are paying .44 cents a pound for our feed, we absolutely count pennies when growing them out.
Our third batch is on 18% and so far seem to be doing fine.
