“…Furthermore, the mechanization of milking female donkeys and mares is necessary to improve milk productivity and quality [105,106]. Since the milk yield is closely related to the morphological characteristics of the mare's and donkey's udders, these must be taken into account in machine milking [107].…”

Donkey milk (DM) has been known in the world for 5000 years for its benefits for human nutrition and health. Nowadays, DM has become more and more attractive as a commercial product. DM contains several physiologically functional components, including high-quality whey proteins, vitamins, important minerals, unsaturated fatty acid and bioactive components. Therefore, it is not only consumed as food but also as a remedy. The average daily milk yield of a female donkey over the entire lactation season was 1.57 ± 1.12 kg/day and fluctuated between 0.20 and 6.00 kg/day. Average milk concentrations (±SD) of fat, protein, lactose, total solids and ash in DM were 0.63 ± 0.41%, 1.71 ± 0.24%, 6.34 ± 0.37%, 9.11 ± 0.95% and 0.39 ± 0.04%, respectively. Interestingly, DM is similar in composition to mare’s milk, and both are similar to mother’s milk. The anatomical and morphological properties of the mammary gland of the female donkey are special and can be compared with those of mare udders. However, the cistern cavity of the mammary gland of female donkeys is characterized by the presence of multiple pockets that open directly into the teat, instead of a single cistern cavity. Therefore, the mammary gland capacity in donkey mare is low and milking technique and routine are of most importance. So far there is no special milking machine for female donkeys and mares. The milking machines used nowadays were initially designed for smaller sheep and goat udders. The company Siliconform, Germany, has set itself the task of developing an optimized milking machine for donkey mares, which is adapted to the anatomical and morphological properties of the donkey mammary gland. Furthermore, it should achieve a physiologically ideal milking process meeting high animal welfare standards for increased milk production with high quality standards.

The article presents the results of studies to establish the influence of the record productivity of mothers’ mares on milk yield and the duration of productive life of mares-daughters of the Lithuanian heavy draft breed. It was found that the high level of milk productivity of mothers during the period of highest lactation (up to 4000 kg of milk) enabled their daughters to become leaders already during the first lactation. With an increase in the record milk yields per lactation in mothers, the heritability coefficient in mother-daughter pairs decreased and turned into negative values. The daughters of mares with record milk yields of up to 8000 are the most dairy among their contemporaries. The research results indicate that intensive milk production of mares during the first lactation can cause a reduction in the terms of their economic use due to the large loads on the developing fragile animal organism. The highest rates of productive life, number of lactations and life-long milk yield were obtained from daughters whose mothers had record milk yields per lactation from 7000 kg to 8000 kg of milk.

“…Linear breeding in industrial horse breeding is used to improve the hereditary qualities of stallions in daughters, in particular, milk production is closely related to the morphological properties of the udder of mares [10]. The main technological features that characterize the suitability of mares for machine milking include: the shape, size of the udder and teats, the uniformity of development of the udder lobes (symmetry or asymmetry of the udder of mares).…”

The presented work is the result of studies of the influence of the linearity of mares of the Russian heavy draft breed on milk productivity, morphological characteristics of the udder and adaptability to machine milking. We examined mares belonging to four lines of stallions: Day laborer, Casket, Svist and Karaul. The calculated milk yield on average per lactation was the highest in mares of the Svist line, and the lowest in the Larchik line. Lifetime milk yield of mares of the Svist line exceeded the same indicator of mares of the Podennik line by 12.13%, of the Karaul line - by 18.51% and the Larchik line - by 47.77%. Studies have shown that Whistle stallions not only contribute to the high milk production of their daughters, but also impart good adaptability to machine milking. Mares of the Larchik line in this population of horses of the Russian heavy draft breed are the least productive and the least adapted to machine milking.
