The authors wish to make the following corrections to this paper [1]:

The body weight given as the weight of the 35th week of age is in fact the weight of the 49th week of age. However, the data presented are correct and the changes do not alter their interpretation.

Main Body Paragraphs Correction

There was an error in the original article. On page 4, Section 2.3. Experimental Procedure, 1st paragraph, the sentence:

“Body weight (g) was measured at hatch and during the experimental period (at week 21, 25, 35 and 69) using a digital table scale (CPA 16001S, Sartorius, Göttingen, Germany) with a weighing accuracy of 0.1 g.”

should be

“Body weight (g) was measured at hatch and during the experimental period (at week 21, 25, 49 and 69) using a digital table scale (CPA 16001S, Sartorius, Göttingen, Germany) with a weighing accuracy of 0.1 g.”

Figures/Tables Correction

Due to the mistake mentioned above, we need to make the following changes to figures and tables:

Replace Figure 1:

Figure 1. Schematic illustration of the experimental setup (A) and related data collection (B). In two consecutive generations, four chicken layer lines were allocated to a diet containing either 300 or 3000 IU of vitamin D3. During the experimental period, data on egg number, egg quality, feed consumption, and body weight were collected as indicated. Post mortem, bone morphometry, bone mineral density, and bone breaking strength were assessed.

With new Figure 1 below:

During the experimental period, data on egg number, egg quality, feed consumption, and body weight were collected as indicated. Post mortem, bone morphometry, bone mineral density, and bone breaking strength were assessed.
