“…For Zn, Fe, Cu, Mn, Se and Co determination, mineralization of milk samples (n 5 112) was obtained modifying the method reported by Fantuz et al (2012). Optimized digestion of thawed milk samples was carried out by placing 1 ml of milk sampled in a Teflon digestion vessel, followed by 3 ml of HNO 3 (65%).…”

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.

“…The high sodium values might be attributed to multiple additions of sodium chloride during the cheese production and to the long ripening time. Furthermore, the sodium content in donkeys' milk is about two times higher in comparison to sodium content found in caprine or bovine milk (Soliman 2005;Fantuz et al 2012). The cheese in this study could be characterized as rich in magnesium and potassium, since determinated values of these minerals (Table 1) were significantly higher than maximum values reported for other types of cheese including hard cheeses made from bovine or caprine milk (Gambelli et al 1999).…”

“…The quantity of milk minerals including trace elements depends on a number of factors such as stage of lactation, feeding programs, genetic characteristics and environmental conditions (Gambelli et al 1999;Fantuz et al 2012). Moreover, mineral content in dairy products is also influenced by applied technological treatments.…”

Cheese cannot be produced solely from equine or donkeys' milk, because of the unique physico-chemical properties of these milks. The purpose of this study was to characterize a novel dairy product, cheese produced from donkeys' and caprine milk mixture (60:40% v/v), regarding its chemical, microbiological, textural and sensory properties. Fully ripened cheese was classified as a high-fat, extra-hard cheese, with high sodium (29.97 g.kg −1 ), magnesium (3.07 g.kg − 1 ) and potassium (4.70 g.kg − 1 ) content. The characterization by lab-on-a-chip electrophoresis revealed lysozyme, α-lactalbumin, immunoglobulins and casein fractions. Palmitic (C 16:0 ) and oleic fatty acids (C 18:2 n9-cis ) with 25.11 and 24.70%, respectively, were found at the highest concentrations. The medium-chain fatty acids account 18.21% of the total fatty acid content in analysed cheese samples. Escherichia coli, Salmonella spp., Enterobacteriaceae, coagulase-positive staphylococci, Listeria monocytogenes, Bacillus cereus, Clostridium perfringens as well as moulds were under the limit of detection in all analysed samples. After 6 months of cheese ripening (0.94 a w , pH 4.71), total bacterial count, the counts of lactic acid bacteria and yeasts were 6.34±0.03, 4.80±0.10 and 5.81±0.11 log CFU.g −1 , respectively. The texture of mature cheese was moderately hard and crumbly. The cheese was described as very salty with strong pronounced creamy, fatty and acidic taste. The characterized donkey/caprine cheese could position this type of cheese as a high-quality functional product, thus having a potential impact on the market.

“…Several studies conducted on donkey milk in terms of composition emphasized the lipid content, characterized by a high occurrence of essential fatty acids, with special importance for the diet of infants with Cow Milk Protein Allergy [42], and also the content of essential elements, which emphasize balanced contents of both macro-elements K, P, Ca, Mg, Na, and micro-elements, Cu, Zn, Ni, Cd, Fe [17,43,44].…”

Analysis of Environmental Factors’ Impact on Donkeys’ Colostrum Quality

Abstract:Colostrum is a natural product, issued by both mammals and humans in the first week of lactation. Among different species, donkey colostrum is considered to have, in addition to a valuable composition in nutrients and immune factors, an outstanding similitude with human colostrum. In this context, and taking into account the scarcity of available data concerning the interaction between climate factors and colostrum quality, a trial was conducted aiming to identify the possible influence of environmental factors on donkey colostrum nutritional traits. A stock of 175 jennies from 7 farms located in Cluj and Sălaj Counties was analyzed over a 7-day postpartum period. During the experimental period, the daily temperature, humidity, and wind velocity data were collected. Strong positive correlations are reported between the studied colostrum nutritional traits (fat, protein and lactose). Testing the impact of some environmental parameters upon nutritional content of donkey colostrum indicated three factors that have an influence on the nutritional quality of donkey milk colostrum, labelled as: colostrum nutritional traits, environmental air traits and some colostrum nutritional traits, and climatic traits and some colostrum nutritional traits.
