Effects of Dietary Betaine on the Secretion of Insulin-like Growth Factor-I and Insulin-like Growth Factor Binding Protein-1 and -3 in Laying Hens
Published:October 19, 2010
ABSTRACT : The principal objective of this experiment was to determine the effects of dietary betaine on IGF-I, IGFBP-3 and IGFBP-1 secretion and IGF-I mRNA gene expression in the serum and liver of laying hens. A total of 72 ISA-Brown laying hens were fed with four different levels of betaine (0, 300, 600, 1,200 ppm) based on a corn-soybean meal diet containing 2,800 kcal/kg of metabolizable en...
A highly technical paper. We knew that natural Betaine is recommended to increase breast meat yield but in this paper, authors examine the growth at micro levels and now a field worker could fully understand how Betaine work in diet.
