“…In a study by Doreau et al (1986), lactose and energy intake by the suckling foal increased daily, whereas fat intake decreased and protein intake remained constant during the first 8 wk of lactation. In the current study, the lactose curve (Figure 1) showed a different shape with a continuous increase during the lactation period, which agrees with other authors (Mariani et al, 2001).…”

Milk yield and composition data from 7 nursing Lusitano mares (450 to 580 kg of body weight and 2 to 9 parities) were used in this study (5 measurements per mare for milk yield and 8 measurements for composition). Wood's lactation model was used to describe milk fat, protein, and lactose lactation curves. Mean values for the concentration of major milk components across the lactation period (180 d) were 5.9 g/kg of fat, 18.4 g/ kg of protein, and 60.8 g/kg of lactose. Milk fat and protein (g/kg) decreased and lactose (g/kg) increased during the 180 d of lactation. Curves for milk protein and lactose yields (g) were similar in shape to the milk yield curve; protein yield peaked at 307 g on d 10 and lactose peaked at 816 g on d 45. The fat (g) curve was different in shape compared with milk, protein, and lactose yields. Total production of the major milk constituents throughout the 180 d of lactation was estimated to be 12.0, 36.1, and 124 kg for fat, protein, and lactose, respectively. The algebraic model fitted by a nonlinear regression procedure to the data resulted in reasonable prediction curves for milk yield (R 2 a of 0.89) and the major constituents (R 2 a ranged from 0.89 to 0.95). The lactation curves of major milk constituents in Lusitano mares were similar, both in shape and values, to those found in other horse breeds. The established curves facilitate the estimation of milk yield and variation of milk constituents at different stages of lactation for both nursing and dairy mares, providing important information relative to weaning time and foal supplementation.

“…The decreases in total N and casein N contents of Haflinger mare's milk from day 4 to day 180 are in agreement with the observations reported by other studies (Minieri and Intrieri 1970;Mariani et al 1993Mariani et al , 2001). The same trends were observed in other breeds and/or for shorter lactation periods (Neseni et al 1958;Bowman and van der Schee 1978;Gibbs et al 1982;Oftedal and Jenness 1988;Doreau et al 1990;Smolders et al 1990;Mariani et al 1993;Csapó-Kiss et al 1995).…”

P. 2005. Mare milk nitrogen fractions during lactation and determination by reversed-phase HPLC of the major whey proteins. Can. J. Anim. Sci. 85: 93-99. The aim of this research was to describe the changes of the nitrogen fractions in milk of Haflinger nursing mares and in particular to determine the whey protein content and distribution, and their evolution throughout the first 6 mo of lactation. Samples were collected by hand-milking on days 4, 20, 40, 60, 80, 120, 150 and 180 post-partum. Nitrogen fractions were determined by Kjeldahl on 80 samples from 10 mares, while HPLC separation of whey proteins was conducted on 40 samples from 5 mares. The total N, casein N, and true whey protein N contents showed a statistically significant decrease from day 4 to day 40, and then remained unvaried. In general, the nitrogen distribution of mare's milk significantly changed between day 4 and day 20 and then remained almost unchanged until day 180 (except for the day 150 value, which showed a statistically significant increase for CN × 100/TN). β-Lactoglobulin and serum albumin contents showed a marked reduction, of 27 and 45.5%, respectively, between day 4 and day 20, and then remained unchanged; α-lactalbumin and immunoglobulins contents had a reduction of 24.7 and 38.3%, respectively, between day 4 and day 20, and another decrease between day 20 and day 40, of 20 and 32.8%, respectively. All whey proteins, expressed as a percentage on the total sum of the four whey proteins considered, did not vary significantly during lactation. However, the sum on the two whey proteins of mammary gland origin (β-Lg + α-La) increased between day 4 and day 20 by 6.3%, and between day 20 and day 40 by 3.8%; the sum of the whey proteins of blood origin (SA + Ig) showed an opposite trend, with a decrease by 14.5% between day 4 and day 20 and by 11% between day 20 and day 40.

The colostral period of mares is much shorter than that of cows, and the colostrum shows significant differences from normal milk only on the first day after foaling (Neseni et al. 1958;Ullrey et al. 1966;Csapó et al. 1995). 93Abbreviations: HPLC, high pressure liquid chromatography; N, nitrogen; TN, total nitrogen; CN, casein nitrogen; NCN, non-casein nitrogen; NPN, non-protein nitrogen; d, day of lactation; β-Lg, β-lactoglobulin; α-La, α-lactalbumin; SA, serum albumin; Ig, immunoglobulin; CV, coefficient of variation Can.

“…Recent clinical studies confirm ass's milk feeding as a safe and valid treatment of most complicated cases of multiple food intolerance [7]. However, information on ass's milk composition [11,26,37,43] is more limited than that on mare's milk [18,19,29,30,33,38], which has also been studied as an infant food [5,15].…”

-Ass's milk yield and chemical composition were investigated in two lactations at d 28,45, 60, 75, 90, 105, 135 and 150 after parturition. Milk yield per milking (averaging 740 mL) of 6 asses of Martina Franca (n = 3) and Ragusana (n = 3) breeds, which quickly adapted to the milking machine procedures, increased in the second (or third) milking per day but was unaffected by stage of lactation or breed. Year of lactation, stage of lactation, breed and milking time did not influence the gross composition of the milk, except for fat and protein contents. The overall average protein percentage (1.72 g·100 g -1 of milk), showing a significant negative trend throughout lactation, was characterised by low casein (47.3% of crude protein) and whey protein contents (36.9% of crude protein). A specific whey protein profile was also found, being the relative percentage on total whey protein 4.48%, 6.18%, 29.85%, 21.03% and 22.56% for respectively lactoferrin, serum albumin, β-lactoglobulin, lysozyme and α-lactoalbumin. The low average fat content of ass's milk (0.38 g·100 g -1 of milk), showing a high individual variability, was significantly affected by the year of the study; the lipid fraction was also characterised by high levels of linoleic (average 8.15 g·100 g -1 of total fatty acids) and linolenic acid (average 6.32 g·100 g -1 of total fatty acids). The ash content of ass's milk (0.39 g·100 g -1 of milk) was constant throughout the experimental period and showed high levels of Ca and P, the ratio of which, ranging between 0.93 and 2.37, was on average 1.48. 135 et 150 jours après la mise bas. Au total, 6 ânesses de race Martina Franca (n = 3) et de race Ragusana (n = 3), rapidement adaptées à la traite mécanique, ont été utilisées. La production laitière par traite et par jour (en moyenne 740 mL) a été supérieure lors de la seconde (ou troisième) traite. Elle n'a été affectée ni par le stade de lactation ni par la race. L'année de lactation, le stade de lactation, la race et l'heure de traite n'ont pas influencé la composition brute du lait sauf ses teneurs en lipides et en protéines. Le pourcentage de protéines (moyenne de 1,72 g·100 g -1 de lait) a eu tendance à diminuer significativement tout au long de la lactation, et a été caractérisé par une teneur réduite en caséine (47,3 % des matières azotées) et en protéines sériques (36,9 % des matières azotées). Un profil particulier des protéines sériques a été mis en évidence, avec un pourcentage relatif par rapport aux protéines sériques totales de 4,48, 6,18, 29,85, 21,03 et 22,56 %, respectivement, pour la lactoferrine, la sérum albumine, la β-lactoglobuline, le lysozyme et l'α-lactalbumine. La faible teneur du lait en matières grasses (0,38 g·100 g -1 ) a été caractérisée par une variabilité individuelle élevée. La fraction lipidique a présenté des niveaux élevés d'acide linoléique (moyenne de 8,15 g·100 g -1 d'acides gras totaux) et linolénique (moyenne de 6,32 g·100 g -1 d'acides gras totaux). Le contenu en cendres (0,39 g·100 g -1 de lait) n'a pas var...
