Derivation of multivariate indices of milk composition, coagulation properties, and curd yield in Manchega dairy sheep

This study approaches the interrelation patterns between composition of milk and whey, curd yield, chromaticity, syneresis, technological quality Manchega sheep using multivariate factor analysis. In addition, effect main husbandry components (flock, prolificacy, season year, stage lactation, parity) on common latent factors that define pattern variation was assessed. For this purpose, 1,200 individual ewe samples from 4 different flocks registered under Protected Designation Origin Queso Manchego were analyzed (50 ewes/flock). Samples collected in 2 seasons year (spring autumn) at 3 time points per season: early, mid-, late lactation. The obtained results suggested yield mainly depends composition, retention water is related to coagulation traits. Thus, moisture content could be useful indicators assess efficiency intended for cheesemaking, regardless analysis properties. Finally, terms husbandry, a direct flock lactation observed all factors, with lower influence parity.
