In the field of dairy cattle research, it is of great interest to improve the detection and prevention of diseases (e.g., mastitis and ketosis) and monitor specific traits related to the state of health and management. During the standard milk performance test, traditional milk traits are monitored, and quality and quantity are screened. In addition to the(More)
The composition of milk is crucial to evaluate milk performance and quality measures. Milk components partly contribute to breeding scores, and they can be assessed to judge metabolic and energy status of the cow as well as to serve as predictive markers for diseases. In addition to the milk composition measures (e.g., fat, protein, lactose) traditionally(More)
To decipher on a molecular level the role of protamine phosphorylation in spermiogenesis, clupeine Z species containing one, two or three serine phosphates were prepared utilizing a recently developed chemical procedure. The melting of complexes with calf thymus DNA showed that thermal stability decreases with increasing degree of phosphorylation. The(More)
The influence of protamine phosphorylation upon the conformation of nucleoprotamine complexes was studied at different ionic strengths using circular dichroism. The sharp onset of CD spectral changes upon decreasing the NaC1 concentrationwas correlated with the beginning of complex formation and can be used to determine apparent binding affinities in terms(More)
