Why the study?

Does dietary betaine affect IGF-I and IGFBP secretion in laying hens?

Structured PICO

Does dietary betaine affect IGF-I and IGFBP secretion in laying hens?

P

Population

72 ISA-Brown laying hens

I

Intervention

Dietary betaine at 300, 600, or 1,200 ppm added to a corn-soybean meal diet (2,800 kcal/kg ME, 16% CP) for four weeks

C

Comparator

Control diet (0 ppm betaine)

O

Outcome

IGF-I, IGFBP-3 and IGFBP-1 secretion and IGF-I mRNA gene expression in serum and liversurrogate

Dietary betaine supplementation alters the IGF system in laying hens, increasing IGF-I and IGFBP-3 while decreasing IGFBP-1.
