英文摘要	The purpose of this study was to determine goat milk physicochemical parameters during the feed scarcity season. An evaluation was made for 398 milk samples from 80 multiparous goats belonging to three different production systems: (S1) mechanized milking grazing pasture and harvested residue (alfalfa) and grain supplemented; (S2) system grazing native pasture; and (S3) system grazing native pasture and grain supplemented. The general averages were: fat (FT) 4.0 +/- 0.20%, protein (PR) 3.3 +/- 0.05%, lactose (LC) 4.9 +/- 0.09%, nonfat solids (NFS) 8.9 +/- 0.13%, total solids (TS) 14.5 +/- 0.20%, temperature (TM) 24.6 +/- 1.06 degrees C, and acidity (pH) 6.7 +/- 0.049. Most of the physicochemical components of milk were affected (p 0.0001) by the production system x month interaction and production system x group x month interaction. The FT content was higher (p < 0.05) in S2 (4.56 +/- 0.18) than in S1 (3.64 +/- 0.20) and S3 (3.50 +/- 0.20). LC differed (p < 0.05) in S2 (5.07 +/- 0.08) than in S1 (4.77 +/- 0.09) and S3 (4.70 +/- 0.09). No differences were observed for the rest of the variables (p < 0.05) among the production systems. The study unveiled a higher content of FT, LC, NFS, PR, and TS for S2 than for S1 and S3. This higher content may be explained because S2 only grazed on herbs and shrubs, in contrast to S1 and S3 which were additionally supplemented with grain concentrates.
