The quality of milk of goats of Saanen, Alpine and Nubian breeds

Abstract

Dairy goat breeding is becoming more widespread, both in the world and on the territory of the Russian Federation, as goat milk is recognized as an easily digestible dietary product with high nutritional and biological value. The most common goat breeds in Russia which are suitable for the industrial milk production are Saanen, Alpine, and Nubian breeds. The studies were carried out in the laboratory of the department of processing technologies and storage of animal origin produce FSBEI HE RGAU - Moscow Agricultural Academy named after K. A. Timiryazev and in the laboratory of technological control VNIMI. The highest milk yield for 305 days of lactation was found in goats of the Saanen breed, which significantly exceeded the milk yield of alpine goats. The mass fraction of fat in the milk of goats of the Nubian breed was the highest, in the milk of goats of the Alpine breed and significantly exceeded this indicator in the milk of goats of the Saanen breed. The highest protein content in milk was found in goats of the Alpine breed than in goats of the Saanen and Nubian breeds. At the same time, when evaluating goat milk, it is necessary to take into account its differences from the established parameters for cow milk: a higher content of somatic cells; low freezing point; inconsistency in the alcohol sample to the thermal stability groups of the cow.

“…Banat’s White has a milk yield between 370 and 400 kg/lactation and a litter size between 200 and 225% [ 47 ]. French Alpine is one of the most popular exotic breeds in Romania, with a milk yield between 525 and 585 kg/lactation [ 48 ] and an average litter size of 115% [ 49 ].…”

Diversity of milk traits in 25 goat breeds

“…In the world, Saanen is a popular breed known as a goat breed with high productivity, but other breeds need to be explored, especially for the milk trait. Saanen had higher milk yield compared to Alpine and Nubian for 305 days of lactation [4]. Among the Mediterranean goats, Murciano-Granadina goats had the highest milk yield, fat, and protein contents compared to Maltese, Sarda, and Sarda Primitiva [5].…”

“…The evolution of the presence of somatic cells in milk during lactation is quite controversial; while some authors reported that the SCC remains unchanged throughout the lactation period [52,54], other researchers found a significant increase of the SCC as the stage of lactation advanced [55,56]. The SCC score is used for the evaluation of milk quality, being correlated with the concentration of lactose, udder health and hygiene and dependent on many factors such as breed, month of milking and farming conditions [52][53][54][55][56][57][58].…”
