The SC composition (SC types and their percentages in total SCC) in milk varies depending on many factors: animal species, breed, stage of lactation, genetics, parity, day-to-day variation, diurnal variation, milking interval, time of sampling, sampling procedures, stress and trauma, management factors, and seasonal and storage procedures (IDF 466/2013).
This even odd cycle parity reflects the variations in inter-hemispheric strengths of the solar magnetic field leading to different temporal distributions of sunspots in the two hemispheres.
Apart from Ethiopia, where we observed a variation by parity, it was surprising to find no significant association between parity or birth interval and modern contraception use in the postpartum period.
The overall caesarean birth rate was 25.7%, with substantial variation across parity and prior caesarean group strata.
Mothers were selected purposively on the basis of having a baby in the last three months before the interview and variation by parity.
In conclusion, our data demonstrate that a classically semelparous plant exhibits variation in parity expression that is consistent with adaptive phenotypic plasticity.
This work demonstrates that reproductive effort occurs along a semelparous-iteroparous continuum within a "semelparous" organism, and that variation in parity occurs within populations as a result of phenotypic plasticity.
The results showed that only BMI and parity were significant sources of variation within normal spectra.
We aimed for variation in age, parity, medical risk status, socioeconomic status, ethnicity, and urban vs. rural residence.
Variations in age, parity and education level were considered in the selection of study participants.
