Using two groups of birds with each group consisting of 8,000 white leghorn caged layers in their pullet year which had been producing for five months. After feeding the test group 60 lbs. of diatomaceous earth per 1 1/2 tons of standard mixed feed (17% protein) for 2 1/2 months the following results were observed:
1. There appeared to be less flies around the test group.
2. Droppings are of a drier consistency, making for easier cleaning of the house.
3. 75% less deaths in the test group.
4. A 2-4 case per day increase in egg production by the test group as compared to the control group |
