SUMMARY
Physical-chemical composition 01 in natura goat milk from cross Saanen throughout lactation period
The analyzed milk samples were collected from cross Saanen goats of different ages and different cross breeding types throughout the lactation period, from September 1996 to December 1997. For the physical-chemical characteristics measured in this experiment, the following average values were obtained, followed by their respective standard deviations: pH (6.69±0.20); acidity (12.96±3.64°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.100g^-1). The lactation period influenced the values of acidity, fat, crude protein and total solids; these values decreased during the initial months and increased at the end of the lactation. The correlations were analyzed among the studied characteristics during the lactation, resulting in positive (p<0.05) acidity/density correlation (r=0.2115), stand out also the positive correlations (p<0.Ol) among fat/total solids (r=0.7715) and crude protein/total solids (r=0.6228).

Key words: Goatmilk, physical-chemical composition, cross Saanen.
