Physical-chemical composition of in natura goat milk from cross Saanen throughout lactation period

The analyzed milk samples were collected from cross Saanen goats of differe nt ages and different cross breeding types, throughout the lactation period , from September 1996 to December 1997. For the physical-chemical character istics measured in this experiment, the following average values were obtai ned, followed by their respective standard deviations: pH (6.69+/-0.20); ac idity (12.96+/-3.64 degrees D); density (1.030+/-0.009mg.cm(-3)); fat (3.83 +/-1.04%); crude protein (3.34+/-0.73%) and total solids (12.25+/-1.94g.100 g(-1)). The lactation period influenced the values of acidity, fat, crude p rotein and total solids; these values decreased during the initial months a nd increased at the end of the lactation. The correlations were analyzed am ong the studied characteristics during the lactation, resulting in positive (p<0.05) acidity/density correlation (r=0.2115), stand out also the positi ve correlations (p<0.01) among fat/total solids (r=0.7715) and crude protei n/total solids (r=0.6228).
