Broiler Breeder Laying Hens Study
|
 |
|
We ran a Poultry Trial/Test which started on August 8, 2000, on a flock (which was just under 12,500 birds in size) of day-old Broiler Breeder Chicks. Bio-Ag Consultants & Distributors prepared a specialized feed for this flock, which contained our own Mineral Premix plus our Probiotic, Enzolac. This study ran until February 10,2001, when the hens finished up. This study is now completed and all the data complied. The following are the results.

Of Special Note
|
Mortality of laying hens placed versus hens shipped
|
During this stretch of time, we experienced one of the hottest streaks (lasting for 7-8 days) on record in 2001.
|
Despite this heat, look at the results....131.4 + 2% chicks per hen housed equals 134.028 chicks
|
Total Hatched, without culls was 83.55%
|
The average of all hatched was 81.9%
