Dextrose equivalence of maltodextrins determines particle morphology development during single sessile droplet drying.

Particle morphology development during spray drying is critical to powder properties. The aim of this study was to investigate whether the dextrose equivalence (DE) of maltodextrins can be used as an indicator for the final particle morphology. Maltodextrins were characterized on glass transition temperature (T) and viscosity, where low DE-value maltodextrins exhibited higher T and viscosity than high DE maltodextrins (≥21).

[Milk cell count as a selection criterion in breeding dairy cattle with improved resistance to mastitis].

The cell counts in the milk of female progeny of thirty-one bulls of the Meuse-Rhine-IJssel breed were determined in three breeding areas in the Netherlands, viz., in the provinces of Overijssel, Gelderland and North Brabant. The individual cell counts of the milk of 1,741 females in their first lactations were determined in study I.

Effect of bull selection for somatic cell count in first lactation on cell counts and pathogens in later lactations.

Somatic cell counts were measured one time on Meuse-Rhine-Ijssel cattle in The Netherlands. Experiment 1 involved 1,741 first lactation daughters of 31 bulls. Eleven bulls with daughters with either high or low average cell count were selected for further study of their daughters in third and fourth lactation.

[Does selection for characteristics of the udder, teats, ease of milking and udder health offer any prospects of improvement of resistance to mastitis? (author's transl)].

Improvement of resistance to mastitis by indirect selection for udder traits, ease of milking and milk cell counts is discussed. --Selection for less pendulous udders with shorter teats is practised. Genetic variation in udder and teat measurements between and within sub-populations of Dutch Friesian (DF) and Meuse-Rhine-IJssel (MRY) cattle in first lactations is important (Table 1).
