In tropical countries such as Thailand, dairy cows particularly raised in small-holder farms are confronted by a problem of improper nutritional management and its consequences, which may lead to impair their production, health and fertility. This review attempted to summarize some nutritional factors influencing reproductive performance especially during postparturient period. The small-scale ...

Two variants of a sample holder were constructed for SAXS (small angle X-ray scattering) and freeze fracture studies of colloid systems during shear stress. The detailed construction of both variants is described. The SAXS investigations give information about the structural changes in the range of nm’s, and the freeze fracture technique makes possible the imaging of the μm-scale morphology. Co...
