The influence of stallions on the properties of the udder of daughters

Abstract

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.

Milk Properties and Morphological Characteristics of the Donkey Mammary Gland for Development of an Adopted Milking Machine—A Review

“…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].…”
