Variation und Eignung von physiologischen Merkmalen des Glukosetoleranztestes für die indirekte Eigenleistungsprüfung von Jungbullen

Abstract

Abstract. Title of the paper: Variation and suitability of physiological indicators of the glucose tolerance test for the indirectly evaluation of young bulls The parameters of glucose tolerance test are suitable for an additional recommendation for the valuation of the breeding bulls before the start of test could be given. This show the Variation, the genetic determination and the mean correlations between physiological indicator and estimated breeding value by 0.40 to 0.50. The offspring's breeding value is suitable equivalent examined physiological indicators. These relationships are affected by factors such as experimental conditions, age and nutritional State of animals.
