Metabolism, a manifestation specific to life, represents the set of physical and chemical processes through which living matter achieves continuous renewal to function and organize the specific activity. The physical-chemical composition of goat milk is conditioned by breed, individuality, area, and age. This study analyzes the physical-chemical composition of milk from a population of Carpathian goat breed, in the first seven postpartum days (first, third, and seventh day) according to age (primiparous and multiparous) to observe the physical-chemical changes from colostrum to milk. The physical-chemical parameters analyzed were: fat (g/100 g); protein (g/100 g); casein (g/100 g); lactose (g/100 g); solid non-fat - SNF (g/100 g); total dry matter (g/100 g); pH; freezing point (FP); urea mg/dl; somatic cells count - SCC/ml x 1000; total bacteria count - TBC/ml x 1000. Results highlight the intense changes that occur at the physico-chemical level of goat's milk to cover the nutritional requirements of the newborn goat and indicate the health status of the mammary gland.

Buffalo milk due to its high fat content from the energy point of view is more valuable compared to cow's milk. The percentage of fat varies depending on the stage of lactation, season, individual, health, animal age and diet. The study of the chemical composition and the antioxidant capacity of buffalo milk is required for both scientific and technological considerations, given the importance of this type of milk in the consumer's diet. The purpose of this study was to evaluate the antioxidant capacity and the physico-chemical composition of buffalo milk by lactation. Buffalo milk can have different qualities, so the quality of buffalo milk is also determined by its content in its components (protein, fat, lactose, vitamins, fatty acids, water content, antioxidant capacity). The physicochemical parameters and antioxidant capacity were influenced by lactation, presenting the highest values in lactations III and IV. During lactation I, parameters such as fat, protein and lactose showed a content of 7.88, 4.35 and 4.71%, respectively. Furthermore, in lactation IV, fat, protein and lactose had increased, showing the content of these parameters as follows 9.53, 4.68 and 4.77%. Antioxidant capacity of buffalo milk showed the highest numbers in lactation III (360.1) and IV, 358.9 µg/ml. From all of the analyzed parameters, only total dry substance content presented the most increased values 18.9% in lactation I. [ABSTRACT FROM AUTHOR]

Donkey milk is considered a substitute for breast milk. Because of its nutritional and compositional properties it is very close to breast milk. Equine asinus can be considered suitable for feeding newborns, against cow's milk, which can cause intolerance. We determined the physico-chemical parameters of donkey milk with CombiFoss FT. The total germ count (TNG) was analyzed by BactoScan and the total number of somatic cells (TNS) by Fossomatic FC. Determination of heavy metals in milk was performed by mass spectrometry to identify Pb, Cd, Cu and Zn. Heavy metals are present in the environment but also in food and can cause serious health problems to the consumer. For the consumer, the main source of cadmium exposure is the food they consume, water and smoking. Cd contamination of dairy milk may also be due to the use of Cd-based chemicals, fertilizers, feed and waste water. [ABSTRACT FROM AUTHOR]

Safety and hygienic quality of milk is conditioned by animal health and hygiene of operated shelters, milking hygiene, staff, storage and cooling of milk immediately after milking, transport to the collection centers, processing and recovery units, and compliance with cold chain distribution network and marketing of milk (Miresan Vioara et al., 2009). All these are important links in quality management and milk as raw material milk products from producer to consumer. The food markets of Campia Turzii and Turda are small producers who sell milk from villages surrounding these cities. Milk samples were taken from seven sources of supply to different markets traders, which were performed on the physical-chemical milk fat content, protein, but the somatic cell count and total bacterial count. The results obtained on these quality parameters show that milk from these producers is within quality standards, but with the necessity to improve hygiene conditions at harvest and storage of milk sold in food markets.

Research has targeted milk quality parameters collected morning and evening milking on three sequences. The following parameters were analyzed: fat, protein, lactose, somatic cell count and weight of fatty acids depending on carbon chain (Jensen, R.G., 2002; Kurtz, F.E., 1987). Taking into account the fat content in both the morning milking and at evening, it increases the dynamic sequences of milking, in the sense that the second sequence of milking the fat content is higher by 75% from the first sequence milking. Differences between milking are very small and insignificant. A different aspect is the evolution of the milk protein content, meaning that it has a constant character, maximum differences of 5% between the second and third sequence of milking sequence of events, look at developments are observed and lactose content in milk. With regard to content in somatic cells, their development is of a tortuous, but at the same time on three different sequences of milking. Of fatty acids sequences have a significant weight in the morning to evening milking are palmate and oleic acids and with low are mostly the other fatty acids (myristic, lauric and caprylic).

Milk quality is influenced by many factors including rank lactation This study aims to present the evolution of the main quality parameters of milk as the fat, protein, lactose, dry matter and the number of somatic cells for the first five lactations in Bălţată Românească breed during twelve official controls, starting in June 2015 until the month of April 2016. The biological material studied was represented by three herds of dairy cows in three farms from Sălaj County (Crasna, Marin and Bodia villages). Analyzing qualitative parameters of milk obtained from the herds in lactation 1 during the 12 controls, there was a percent of 3.58% fat, 3.05% protein, 4.49% lactose and 8.48% dry substance and less than 100,000 cells/mL for SCC. in Crasna farm. These parameters varied over the five lactations, the highest values being ranked in lactation five. Herd from Marin farm presented a fat content of 4.44% in lactation 2, while the lowest percentage of fat was recorded in lactation 3 (3.66%). Regarding the protein, the highest percentage was obtained in lactation 2 (3.70%) and the lowest in lactation 1 (3.39%). In the farm from Bodia the values were intermediate between the two other farms. Lactation rank affects milk quality, so in lactation 1 there were recorded the lowest values of quality parameters of milk. Somatic cell count was under 100,000 for all three farms, suggesting a good health status of the herds. [ABSTRACT FROM AUTHOR]

Research aimed the quality parameters analysis collected from three milk collection centers in the NW Transylvania which used to obtain different types of milk based products. The average values obtained for milk collection centre 1 was 3.78±0.04% fat, 3.27±0.02% protein, 8.62±0.04% dry matter, density 27.97±0.030L, SCN 239.97/ml"1000 and TGN 102.90/ml"1000; for the average collection centre 2 were obtained 3.76±0.03% fat, 3.27±0.01% protein, 8.62±0.03% dry matter, density 27.98±0.040L, SCN 194.07/ml"1000 and TGN 118.67/ml"1000; for the average collection centre 3 were obtained 3.69±0.03% fat, 3.24±0.01% protein, 8.61±0.02% dry matter, density 27.92±2.140L, SCN 131.93/ml"1000 and TGN 153.97/ml"1000.

Lipids are major components of buffalo milk with great implications in nutrition and economical aspects. The nutritional value of buffalo milk is derived from its complex chemical composition and its high rate of assimilation. Major fatty acids found in both milk and cheese were: palmitic acid (16:0), oleic (18:1) and stearic (18:0). The ratio between UFA/SFA was 0.3, lower than the threshold of 1.5 which is considered to not raise negative health effects. [ABSTRACT FROM AUTHOR]
