One hundred and eight, 19-wk-old pullets (Shaver White Leghorns) were placed in cages (6 birds per cage) and allocated to experimental diets based on BW in a completely randomized design to give 6 replicates per diet. The diets were fed from wk 19 to 27. The birds had free access to feed and water throughout the experimental period. Hen-day egg production (HDEP , number of eggs laid per d/number of hens) and average egg weight (AEW ) per cage were recorded on daily basis. Feed intake was determined on weekly basis and BW at the end of wk 21, 23, 25, and 27. All eggs collected on the 5th d of wk 22, 24, and 26 were submitted for egg quality analyses on the same day.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
