Résumé:
Milk has been a very important part of the diet from time immemorial, both for
humans and animals. Two (02) milk samples were collected from two different animals (goat
and sheep) from the wilaya of Tiaret.The objective of this work is to assess the quality of raw
sheep's milk and goat's milk from the wilaya of Tiaret. The physicochemical quality of milk
is evaluated by measuring the pH, the reductase test, the acidity. The microbiological
examination involved the enumeration of FAMT, total and fecal coliforms, Staphylococcus
aureus, fecal streptococci and salmonella. The results of the physicochemical analyzes show
that the pH (6.57 - 7.85) and the acidity at (21.62-22.8). And The results of the enumeration
are; FAMT (2.9 × 104), CT (1.03 × 103), CF (3.9 × 10) and streptococci (3.93 × 102).
We recorded the presence of staphylococci in 40% of the samples and a total absence
of salmonella. Our results indicate that sheep's milk and goat's milk from the Tiaret region
average microbiological quality.
