Slow growths, small birds and transparency

A few weeks back, I have observed slow growth rates during the first to the 2nd week. Naturally, I had to look for likely causes of these symptoms. Upon evaluation I identified the following causes: 1. chick source 2. nutrition/feed 3. management. After more evaluation and data collection, I eliminated management partly because even those growers with good management have been affected. So there are only 2 likely suspects: DOC and feeds. Of course, if you point to these two as the likely causes, most probably they will point it back to you or to the other group. So, being a good and sensible poultryman, I only provided a solution to the only thing that I can control, and that is management. I felt that if I waited for confirmation of the problem from the breeding and the feed mill, all the birds with theses observed problems will have already been harvested (and that is what happended by the way!). Anyway, on my part, I advised my growers to do early selection and culling at the 1st week. I also prescribed to give a supplementation containing ATP and Sorbitol to help increase the feed intake during the 1st week in the hope of recovering the delayed days in growth. These management adjustments did very well in controlling the slow growth and the occurrence of small birds but still the runting cases have increased from 4% per month to about 10%! And they say that the feeds and DOC have no problems!
I think, that there was indeed a problem with the DOC, but not with the breeder itself but from the selection at hatchery level. Upon further investigation, it was found out that there are a lot of new hires at the hatchery during this time and this is most likely the true cause. Meanwhile, I also checked the feed content (protein and ME especially) and it showed that these two parameters are below standards.

In conclusion, the slow growth and small birds have been caused by two factors, 1) poor DOC selection at hatchery level and 2) low protein and caloric content. But with all the hiding and the cover ups, who will admit that they were to blame?

Talk about openness and transparency.......
