Book excerpt: Functional traits are the characters of an animal which increase the efficiency not by higher output of product but by reduced cost of input. Udder and reproductive disorders are the imperative functional traits which causes major losses in milk production. Reproduction disorders affect the herd life, reproductive efficiency of cows and are responsible for removal of the cow from the herd. Crossbred cows appear to be more prone to infections and disorders as compared to indigenous breeds. Karan Fries cow is a crossbred of Holstein Friesian and Tharparkar (India) developed at National Dairy Research Institute, Karnal, India. Incidence of abortion, still birth, dystocia, retained foetal membrane, metritis, endometritis, anoestrus, repeat breeding, pyometra and other reproductive disorders in Karan Fries cows were evaluated. Production and reproduction performance traits were found to be influenced by reproductive disorders. Repeatability of anoestrus and abortion were moderate to high in second and third lactation. Metritis was the most severe reproduction disorder. Overall incidence of reproduction disorders was lower in F1 than interbred genetic group of Karan Fries cows.

Book excerpt: Gegenstand dieser Arbeit ist es, den Einsatz der genomischen Zuchtwertschätzung für neue funktionale Merkmale und den Gehalt an Milchinhaltsstoffen auf Ebene der einzelnen Euterviertel in der Milchrinderzucht zu beleuchten. Nach einer allgemeinen Einführung in die genomische Selektion und in das Prinzip der Testherden werden im zweiten Kapitel genetische Parameter und Heritabilitäten für verschiedene Verhaltensmerkmale, für Milchfluss, Eutertiefe, Labienlage und Tage bis zur 1. Brunst geschätzt. Im dritten Kapitel erfolgt eine Schätzung genetischer Parameter und Heritabilitäten für die Milchinhaltsstoffe (Fett, Eiweiß, Lactose, Harnstoff, SCS) und für Hyperkeratosen der Zitzen auf Basis der einzelnen Euterviertel. Ferner werden additiv genetische und phänotypische Korrelationen für diese Merkmale zwischen den Eutervierteln geschätzt. Im vierten Kapitel wird eine genomische Zuchtwertschätzung für die funktionalen Merkmale aus Kapitel eins auf Basis von 777k Genotypen vorgestellt. Die Sicherheit der genomischen Zuchtwerte wird zudem mit einem neuen Ansatz abgeleitet, der trotz geringer Sicherheit der konventionellen Zuchtwerte eine realistische Abschätzung der genomischen Zuchtwerte erlaubt. Im fünften Kapitel werden abschließend die Möglichkeiten beleuchtet, eine genomische Zuchtwertschätzung für funktionale Merkmale in einem Testherdensystem zu etablieren.
