Abstract: The present invention relates to a method for producing a composition which comprises animal protein, comprising (a) isolating precursor cells from perinatal tissue of a mammal; (b) incubating the precursor cells under conditions which lead to a myogenic differentiation of the precursor cells; and (c) harvesting the cells. The present invention also relates to a method for producing precursor cells from perinatal tissue, to animal protein produced according to the invention, and precursor cells produced according to the invention. The present invention further relates to the use of a culture medium which has a reduced content of methionine in comparison to standard medium, to the differentiation of precursor cells, and to a method for the in vitro production of a meat-like composition.

Abstract: Described herein is a method for identifying a farm animal having an impairment of regulative capacity in response to metabolic stress, the method including: a) assessing the value of the nonlinear domain heart rate variability component LMAX of a farm animal based on a heart beat interval data set obtained for the farm animal; and b) comparing the value of LMAX assessed according to (a) with a species specific threshold of LMAX, whereby a farm animal having an impairment of regulative capacity will be identified.
