“…The average donkey milk Co concentration was similar to or slightly lower than that in cow milk (Cashman, 2011). A wide range of variation is reported for the I concentration in cow and goat milk, strongly depending on dietary factors (Nudda et al, 2009;Moschini et al, 2010;Cashman, 2011).…”

“…Average donkey milk concentrations of Mn and Se were lower than in mare milk (Anderson, 1992;Csapó -Kiss et al, 1995;Montgomery et al, 2012), but I concentration was higher (Table 2; Doreau and MartinRosset, 2011). Donkey milk contains lower concentrations of Zn, Fe, Mn and Se compared with milk commonly used for human consumption, such as cow and goat (Park et al, 2007;Cashman, 2011), whereas the Cu concentration is similar to or higher than cow (Anderson, 1992;Cashman, 2011) but lower than goat milk (Park et al, 2007). The average donkey milk Co concentration was similar to or slightly lower than that in cow milk (Cashman, 2011).…”

The aim of this trial was to study the concentration of zinc (Zn), iron (Fe), copper (Cu), manganese (Mn), selenium (Se), cobalt (Co) and iodine (I) in milk and blood serum of lactating donkeys, taking into account the effects of lactation stage and dietary supplementation with trace elements. During a 3-month period, 16 clinically healthy lactating donkeys (Martina-Franca-derived population), randomly divided into two homogeneous groups (control (CTL) and trace elements (TE)), were used to provide milk and blood samples at 2-week intervals. Donkeys in both groups had continuous access to meadow hay and were fed 2.5 kg of mixed feed daily, divided into two meals. The mixed feed for the TE group had the same ingredients as the CTL, but was supplemented with a commercial premix providing 163 mg Zn, 185 mg Fe, 36 mg Cu, 216 mg Mn, 0.67 mg Se, 2.78 mg Co and 3.20 mg I/kg mixed feed. The concentrations of Zn, Fe, Cu, Mn, Se, Co and I were measured in feeds, milk and blood serum by inductively coupled plasma-MS. Data were processed by ANOVA for repeated measures. The milk concentrations of all the investigated elements were not significantly affected by the dietary supplementation with TE. Serum concentrations of Zn, Fe, Cu Mn and Se were not affected by dietary treatment, but TE-supplemented donkeys showed significantly higher concentrations of serum Co (1.34 v. 0.69 mg/l) and I (24.42 v. 21.43 mg/l) than unsupplemented donkeys. The effect of lactation stage was significant for all the investigated elements in milk and blood serum, except for serum manganese. A clear negative trend during lactation was observed for milk Cu and Se concentrations (238%), whereas that of Mn tended to increase. The serum Cu concentration was generally constant and that of Co tended to increase. If compared with data reported in the literature for human milk, donkey milk showed similarities for Zn, Mn, Co and I. Furthermore, this study indicated that, in the current experimental conditions, the mineral profile of donkey milk was not dependent on dietary TE supply.

“…Apart from their effects on protein aggregation (Sievanen et al, 2008;Sandra et al, 2012), variation in mineral content can also alter the nutritional value of milk and milk products (Cashman, 2011a). The role of trace elements in human nutrition has been extensively reviewed (Cashman, 2011b;Gaucheron, 2013); they contribute biological and physiological functions such as the role of Fe in hemoglobin production, Cu and Se in enzyme functioning, Co as a constituent of vitamin B 12 , and Se as a component of glutathione peroxidase, an antioxidant. Further, little is known how trace elements partition between the casein and serum phases of milk, even though this is likely to influence their bioavailability (Cashman, 2011b).…”

The influence of feeding system and lactation period on the gross composition, macroelements (Ca, P, Mg, and Na), and trace elements (Zn, Fe, Cu, Mo, Mn, Se, and Co) of bovine milk was investigated. The feeding systems included outdoor grazing on perennial ryegrass pasture (GRO), outdoor grazing on perennial ryegrass and white clover pasture (GRC), and indoors offered total mixed ration (TMR). Sixty spring-calving Holstein Friesian dairy cows were assigned to 3 herds, each consisting of 20 cows, and balanced with respect to parity, calving date, and pre-experimental milk yield and milk solids yield. The herds were allocated to 1 of the 3 feeding systems from February to November. Milk samples were collected on 10 occasions over the period June 17 to November 26, at 2 or 3 weekly intervals, when cows were on average 119 to 281 d in lactation (DIL). The total lactation period was arbitrarily sub-divided into 2 lactation periods based on DIL, namely mid lactation, June 17 to September 9 when cows were 119 to 203 DIL; and late lactation, September 22 to November 26 when cows were 216 to 281 DIL. With the exception of Mg, Na, Fe, Mo, and Co, all other variables were affected by feeding system. The GRO milk had the highest mean concentrations of total solids, total protein, casein, Ca, and P. The TMR milk had the highest concentrations of lactose, Cu, and Se, and lowest level of total protein. The GRC milk had levels of lactose, Zn, and Cu similar to those of GRO milk, and concentrations of TS, Ca, and P similar to those of TMR milk. Lactation period affected all variables, apart from the concentrations of Fe, Cu, Mn, and Se. On average, the proportion (%) of total Ca, P, Zn, Mn, or Se that sedimented with the casein on high-speed ultracentrifugation at 100,000 × g was ≥60%, whereas that of Na, Mg, or Mo was ≤45% total. The results demonstrate how the gross composition and elemental composition of milk can be affected by different feeding systems.

“…Also it might be explained by the high level of lactoferrin present in human milk. Another possible explanation may be found in the high content of lactose and ascorbate in human milk (Cashman, 2002).…”

It has been widely accepted that breastfeeding is the best food for newborns. Mother's milk provides all the nutritive elements for normal growth and development of infants being considered the first functional food in life. Because it contains a variety of compounds playing a key role in the adequate feeding of newborns, such as oligosaccharides, probiotics, polyunsaturated fatty acids and lactoferrin. Lactoferrin from human milk has been demonstrated to be responsible for the resistance of newborns to infections and also has many biological activities that are essential for an adequate health of infants. Recently, there is also a growing interest in the potential use of lactoferrin for the improvement of bone health and cancer prevention. Milk substitutes and infant formulas play a vital role in infant nutrition when the breastfeeding is not available. The design of infant formula is modeled on the composition of human milk and the current trend in the infant formulas manufacturing is looking to provide not only nutritional compounds but also similar functional effects than human milk.
