mRNA-seq of the jejunum mucosa in LSL and LB laying hens following the variations of dietary calcium and phosphorus levels
Calcium (Ca) and phosphorus (P) are essential micronutrients that are linked to a wide set of biological processes. In laying hens there is still uncertainty about the optimal Ca/P ratio in feed and further strategies for the reliable mineral restriction in poultry diets are required. The dataset is based on Lohmann Selected Leghorn (LSL) and Lohmann Brown (LB) laying hens sampled at peak performance. The experimental design comprises four dietary groups differed in Ca (recommended vs. 15 % reduction) and mineral P (adequate vs. 20 % reduction) levels; 1) control diet (Con; Ca=34.4g/kg, P=5.3 g/kg and Ca/P ratio=7.45), 2) Low Ca and P diet (LCaP), 3)  low Ca diet (LCa), and low P diet (LP). Jejunal transcriptome profiles were assessed by mRNA sequencing in a total of 80 animals (10 hens per experimental group for each laying line) at sampling age of 31 weeks) to approximate the consequences of variable Ca and P supply.
