“…In contrast, when 6 milkings per day were performed, the milk yield per milking showed no improvement compared with that for the 3 milkings per day regimen. Similarly, in Ragusana jennies, increasing the number of daily milkings to 8 did not improve milk yield (Alabiso et al, 2009). There is no evident explanation for this finding considering that multiple milking regimens should more closely mimic the natural maternal behavioral routine of the jennies.…”

Three experiments were conducted on Martina Franca jennies. Experiment 1 tested Wood's model for evaluating the lactation curve. Data from the entire lactation period of 12 jennies were used. The results showed that Wood's model was able to recognize the shape of the lactation curve from pooled data (r(2) = 0.11; P < 0.01), with the lactation peak occurring at 48 d. Individual curves showed wide variability. Experiment 2 aimed to evaluate the effects of the daily number of milkings (1, 3, or 6) and the interval between the separation of foals from dams and milking (2 or 3 h) on milk yield and udder health. Four groups of jennies (n = 5) were considered: 1 × 3H, milked once per day (1×) with a 3-h interval from the time of foal removal (3H) from the dams to mechanical milking (3-h interval); 3 × 3H, milked 3 times per day with 3-h intervals; 3 × 2H, milked 3 times per day with 2-h intervals; and 6 × 2H, milked 6 times per day with 2-h intervals. The milk somatic cell count (SCC) was monitored. Better efficiency was observed for 3 vs. 1 milking per day and for 3-h vs. 2-h intervals. The regimen of 6 daily milkings at 2-h intervals did not increase milk yield and was related to an increase in the SCC compared with 3 daily milkings. In Exp. 3, the effects of the interval from foal removal to milking (3, 5, or 8 h) on yield, gross chemical composition, organoleptic characteristics of the milk, and udder health of the jennies were evaluated. The effects of milking time were also evaluated. Twenty jennies milked twice daily (2×) were subdivided into 4 groups (n = 5): 2 × 3H, with milkings at 1200 h and 1900 h and an interval of 3 h; 2 × 5H, milked at 1200 h and 1900 h with a 5-h interval; 2 × 8H(1), milked at 1200 h and 2200 h with an 8-h interval; and 2 × 8H(2), milked at 0700 h and 1900 h with an 8-h interval. Milk yield was greater by 28.4% when an 8-h interval was used compared with a 3-h interval and at the morning vs. the evening milking. The milk yield per milking was greatest at 0700 h, indicating the existence of a circadian rhythm in milk secretion processes. Intervals of 5 and 8 h caused significant decreases in the fat and lactose content and organoleptic characteristics of the milk, whereas an 8-h interval led to an increase in the SCC. In conclusion, a milking regimen of twice-daily milking at 0700 h and 1900 h with an 8-h interval provided the maximum yield per day. In terms of milk quality, a 3-h interval yielded the best results.

“…Furthermore, current data on donkey milk show its suitability for human consumption when hygiene standards are observed during milking, even though the total bacteria count was found to vary from 2.5 Â 10 2 to 7.4 Â 10 5 cfu mL À1 (minimum and maximum from Alabiso et al, 2009;Colavita et al, 2011;Conte, Calabrò, & Monsù, 2003;Conte et al, 2004;Coppola et al, 2002;Pilla, Daprà, Zecconi, & Piccinini, 2010;Salimei et al, 2000Salimei et al, , 2004bSalimei et al, , 2005aSimoni et al, 2004;Sorrentino et al, 2005Sorrentino et al, , 2010.…”

“…As also observed in horses, studies on dairy donkeys are often carried out in different experimental conditions and highly variable productions are obtained with manual (466 AE 260 mL milk per milking; mean value and standard deviation calculated from Alabiso, Giosuè, Alicata, Mazza, & Iannolino, 2009;Chiofalo, Azzara, Piccolo, Liotta, & Chiofalo, 2004;Guo et al, 2007;Ivankovic et al, 2009) or mechanical milking (772 AE 148 mL milk per milking; mean value and standard deviation calculated from D' Alessandro, De Petro, Claps, Pizzillo, & Martemucci, 2009;Fantuz et al, 2007Fantuz et al, , 2010Giosuè et al, 2008;Salimei et al, 2000;Salimei, Fantuz, Varisco, Maglieri, & Polidori, 2005a;Simoni et al, 2004).…”

“…It must be noted that dietary supplementation with vegetable or marine oils modified the fatty acid profile of horse and donkey milk, even though it had a negative or null effect on the milk fat percentage (Alabiso et al, 2009;Hoffman et al, 1998;Salimei, Bontempo, & Dell'Orto, 1996a;Salimei et al, 1996b). Increased intake of soluble fibre also affects the donkey milk fatty acid composition by increasing the total saturated fatty acid percentage and reducing the total n6 PUFA content (Chiofalo, Piccolo, Riolo, Maglieri, & Salimei, 2006b).…”

A survey on the milk chemical and microbiological quality in dairy donkey farms located in NorthWestern Italy

et al. 2015

There is a growing interest in donkey's milk as food for sensitive consumers, such as infants with cow's milk protein allergy and elderly people. The aim of this study was to carry out a survey on the dairy donkeys farming in Piedmont, Italy. The research was conducted in order to analyze the farm characteristics as well as the chemical and microbiological quality of milk. All the farms were small-sized, family-run, and, in most cases, animals were farmed semi-extensively. The donkey milk from Piedmont farms was characterized by a protein content around 1.5 g/100 mL and a fat content lower than 0.1 g/100 mL. Lysozyme activity was considerably higher than that reported in raw cow milk. The milk microbiological profile greatly differed among the farms. Milk sampled in the farm that performed hand milking showed total viable counts significantly lower than milk collected in the farms equipped with automatic milking. Samples were tested for several pathogens and negative results were observed, except for the detection of B. cereus in one sample. The survey provided useful data for the laying down of recent regional regulation for the production and commercialization of donkey's milk. The results of the survey indicate that further research is needed in order to define the best management and nutritional strategies for the improvement of the quali-quantitative production of dairy donkeys.
