“…The concentrations of macro-minerals vary depending on the breed, diet, individual animal, stage of lactation, and status of udder health (Stocco et al 2019). When comparing sheep breeds versus goat subgroup milk for macro-minerals, the current study found lower K and higher concentrations of Ca, P, and Na, whereas other research studies reported higher concentrations of K for sheep's milk (AL-Wabel, 2008).…”

Characteristics and quality aspects of milk from native ovine Queue Fine de l'Ouest (QFO) and the exotic D'man (DMN) breeds were investigated and compared with those of two subgroups of the local goat population Arbi and Serti. A total of 418 individual milk samples were collected from multiparous lactating animals reared in the continental oasis region of Tunisia. Samples were analyzed for physical parameters (pH, density, and acidity), chemical composition (dry matter, fat, protein, lactose, casein, ash, and casein/protein ratio), mineral concentrations (Ca, P, Na, K, and Ca/P) and microbiological features (total mesophilic aerobic bacteria (TMAB), total coliforms count (TCC), lactic acid bacteria (LAB), sulphitereducing Clostridium (CSR), yeast and molds (Y/M), Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), and Salmonella) according to standard methods. The values obtained for physicochemical, mineral, and microbial parameters revealed noticeable differences in the milk of the four studied breeds. On the whole milk samples, the mean value of pH, density, and acidity in milk collected from sheep breeds appeared higher than in milk collected from goat subgroups. As for milk composition, results showed a remarkable disparity between studied breeds and clear superiority of sheep breeds compared to goat's subgroups in all chemical contents being studied (dry matter, fat, protein, lactose, casein, and ash). The differences are more important, especially for dry matter, fat, protein, and casein content, whereas casein/protein ratio distinguished goat's genotypes, and the highest one was obtained for Serti Subgroup. When comparing sheep versus goat's milk for macro-minerals, the current study indicated lower K and higher concentrations of Ca, P, and Na. The milk of QFO sheep, the richest in casein and protein, was expressed with significantly higher levels of calcium and phosphorus compared to the DMN sheep breed and the two goat subgroups. The microbiological examination evidenced that the milk of both species complies with standard criteria required by the Tunisian legislation on the hygiene of milk and dairy products. The microbial quality of ewe milk was higher than goat milk, based on LAB and Y/M, while goats produced milk with better quality referring to TMAB and TCC counts. No significant differences were found for Staphylococcus aureus and Escherichia coli between examined breeds. Got results highlighted the complete absence of the two dangerous pathogens Salmonella and CSR in all investigated samples of small ruminants' milk.

“…Although there was no distinction in Na concentration, there was a tendency for Na yield to be higher in primiparous buffaloes than in multiparous ones in present study ( p = 0.09). It has been proven that the Na concentration was higher in the multiparous buffaloes than in the primiparous buffaloes, based on an increase in milk production [ 53 ]. Na and K are involved in preserving the osmotic stability between blood and milk; however, the impact of parity on them is indistinct [ 54 ].…”

Colostrum is a vital performance for buffaloes and potentially functional foods in the future. Therefore, this study aimed to evaluate the difference between the parity of buffalo colostrum and mature milk. Twenty pregnant buffaloes (primiparous = 10; multiparous = 10) were assigned to the same diet prepartum and milking routine postpartum. Calves were separated from the dams immediately after birth and colostrum was harvested within 2 h, whilst mature milk was harvested at 7 days postpartum. The colostrum was analyzed for immunoglobulin G and milk composition as the mature milk. The results showed that there was a higher level of protein, solid not fat, and milk urea nitrogen (p < 0.05), with a tendency for higher total solids (p = 0.08) in primiparous buffaloes’ colostrum compared with multiparous. No parity effect was observed in colostrum immunoglobulin G, fat, lactose, and yields of colostrum and composition (p > 0.05). There was no difference in mature milk composition and yield by parity affected (p > 0.05). Compared with mature milk composition, colostrum had a higher content protein, total solids, solid not fat, and milk urea nitrogen (p < 0.05); however, fat and lactose were lower than that of mature milk (p < 0.05). For minerals, multiparous buffaloes’ colostrum had a higher concentration of Fe (p = 0.05), while the mature milk had higher concentrations of K and P compared with primiparous. Buffalo colostrum had higher concentrations of Na, Mg, Co, Fe, and K with a lower concentration of Ca relative to mature milk (p < 0.05). It was observed that parity affected colostrum characteristics rather than mature milk and caused subtle variations in minerals in colostrum and mature milk of buffaloes. As lactation proceeded, both milk composition and minerals in the milk changed drastically.
