“…The observed FT average in S2 is superior to the values reported by Mayer and Fiechter () for the six most common goat breeds in Australia: Coloured, Pinzgau, Saanen, Strahlen, Toggenburg, and White with corresponding FT values of 3.51 ± 0.51, 3.79 ± 0.56, 3.73 ± 0.46, 3.56 ± 0.59, 3.86 ± 0.74, and 3.58 ± 0.71%. These values were even higher than to those reported for French Alpine goats in Mexico (3.96 ± 0.70) and Saanen (3.5 ± 0.92%) (Vega et al., ), as well as to those reported in the same area (4.13 ± 0.66%) in samples taken from milk containers at the herd level (Salinas‐González et al., ).…”

“…(). Mayer and Fiechter () found that pH (6.55 ± 0.08) was slightly inferior in Coloured, Pinzgau, Saanen, Strahlen, Toggenburg, and White goats. The acidity level is of supreme importance in the coagulation process since a pH close to 7 may inhibit the coagulation process in the manufacturing of cheese (Tornadijo, Marra, García Fontán, Prieto, & Carballo, ).…”

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°C, and acidity (pH) 6.7 ± 0.049. Most of the physicochemical components of milk were affected (p < 0.0001) by the production system × month interaction and production system × group × 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.

“…() in the milk of Saanen goats. Mayer and Fiechter () found similar values for the most investigated traits in goats of six breeds in Austria. The SCC determined for the milk of Croatian spotted goats is lower when compared to the higher limit of reference values for goat milk (Regulations on quality of fresh raw milk, ).…”

“…() determined a similar distribution for goats' milk in Poland, but with significant differences depending on lactation stage in concentrations of K and Na, there was a significant increase in Ca and Mg concentrations, as well as an opposite trend for concentrations of Zn, Fe and Cu. The research in Austria with goats' milk showed similar concentrations for Ca, Mg, Na and K (Mayer and Fiechter ). Güler () determined higher concentrations of Cd and Pb (0.63 and 0.06 mg/kg) in goats' milk from Turkey.…”

The research was conducted on days 60, 90, 120 and 150 during the lactation with the aim to determine the effect of lactation stage on the concentration of crucial elements and chemical composition in Croatian spotted goats' milk. Milk yield significantly decreased (from 1.15 to 0.76 kg/day), while the concentration of Ca, Mg, P, Zn and Mo in the milk of the goats significantly increased during lactation. The concentrations of Cr, Cd and Pb in milk were very low, with no significant deviations during lactation. The quality of milk from Croatian spotted goats is adequate compared with other breeds in the surrounding area of Croatia.

“…The addition of water affects the freezing point (FP) of milk so it is used in the industry as a criterion for economic sanction. Although sheep and goat FP is influenced by many factors (i.e., total non-fat solids, breed, stage of lactation, season, and pasteurization) (Antunac et al, 2001;Park et al, 2007;Mayer & Fiechter, 2012;Janstová et al, 2013), both analytical methodology and preservation strategies have major effects on inter-and intra-laboratory quality testing, as well as for routine sampling strategy. Indeed, FP obtained by Milkoscan FT 6000 has a high repeatability and reliable accuracy compared to thermistor cryoscope method, which is the reference method according to IDF (2002).…”

Somatic cell count (SCC), mammary pathogens prevalence, total and specific bacterial counts, antimicrobial residues, macroscopic sediment, water addition, aflatoxins and other contaminants constitute the basis for milk payment-schemes, monitoring and improvement of flock hygiene and health management, and development of analytical surveillance programs in the dairy small ruminants. The present work reviews factors influencing the variation of these variables, including milk analytical methods, storage and preservation, along with management implications during the last two decades. Following farmer and cooperative educational programs, progressive reductions have been reported for total bacterial count and antimicrobial residue occurrence in bulk tank milk. These results were consistent, however, with high values for SCC and specific bacterial populations. Thus, mastitis control programs should be intensified to increase hygiene in milk and economic returns for producers and processors. In addition, the implementation of programs to reduce specific bacterial counts (i.e., psychrotrophs, coliforms, Clostridium spp. spores) and mammary pathogen prevalence (i.e., Staph. aureus, Mycoplasma spp.), as well as the use of combined screening methods for an increased rate of antimicrobial detection, are currently required strategies which are positively valuated by milk processors, industry and consumers. Other contaminants may also be present, but cost-effective screening and analytical systems have not yet been implemented. This review aims to be helpful for troubleshooting milk quality and safety, developing future premium payment systems and industry quality-standards, optimizing management, on-farm risk traceability systems and consumer acceptance.
