The aim of this study was to assess the relationship between temperament and milk performance in cows at different stages of lactation, describing their productivity, metabolic status and resistance to mastitis. This study showed that with increasing lactation, cows’ temperament indicators decreased (p < 0.001) and they became calmer. The highest temperament score on a five-point scale was found in cows between 45 and 100 days of lactation. In the group of pregnant cows, we found more cows (p = 0.005) with a temperament score of 1–2 compared with non-pregnant cows A normal temperament was usually detected in cows with lactose levels in milk of 4.60% or more and when the somatic cell count (SCC) values in cow milk were <100,000/mL and 100,000–200,000/mL, with a milk fat-to-protein ratio of 1.2. A larger number of more sensitive and highly aggressive cows was detected at a low milk urea level. In contrast to a positive phenotypic correlation (p < 0.05), this study showed a negative genetic correlation between the temperament of cows and milk yield (p < 0.001). Positive genetic correlations between temperament scores and milk somatic cells (p < 0.001) and milk fat-to-protein ratio (p < 0.05) were found to indicate a lower genetic predisposition in cows with a calmer temperament to subclinical mastitis and ketosis. On the other hand, the heritability of temperament (h2 = 0.044–0.100) showed that only a small part of the phenotypic changes in this indicator is associated with genetic factors.

Recently, camel milk (CM) has been considered as a health-promoting icon due to its medicinal and nutritional benefits. CM fat globule membrane has numerous health-promoting properties, such as anti-adhesion and anti-bacterial properties, which are suitable for people who are allergic to cow’s milk. CM contains milk fat globules with a small size, which accounts for their rapid digestion. Moreover, it also comprises lower amounts of cholesterol and saturated fatty acids concurrent with higher levels of essential fatty acids than cow milk, with an improved lipid profile manifested by reducing cholesterol levels in the blood. In addition, it is rich in phospholipids, especially plasmalogens and sphingomyelin, suggesting that CM fat may meet the daily nutritional requirements of adults and infants. Thus, CM and its dairy products have become more attractive for consumers. In view of this, we performed a comprehensive review of CM fat’s composition and nutritional properties. The overall goal is to increase knowledge related to CM fat characteristics and modify its unfavorable perception. Future studies are expected to be directed toward a better understanding of CM fat, which appears to be promising in the design and formulation of new products with significant health-promoting benefits.

The first results of the genome-wide associations analysis for fatty acids composition in cow milk by Russian Holsteinized Black-and-White and Holstein breeds were obtained. Genomic regions (QTL) associated with milk fat percentage, fatty acids synthesis, functional parameters of linear type for udder and leg traits, fertility features have been detected.

AbstractOne of main nutritional components in milk are fat. Fats are the main source of energy used by the body. The most important components are fatty acids (FA), which have important biological functions e.g. anti-inflammatory, anti-atherosclerotic, reducing blood pressure. What is more, milk fat in human diet shows health-promoting properties (1, 2). The aim of this study was to compare the fatty acids composition in selected mammals’ milk. A total of 84 milk samples of cow (Holstein-Frisian breed, n = 20), mare (Polish cold-blooded horse, n = 20); sheep (Kamieniecka breed, n = 12), goat (White goat breed, n = 12) were collected from small individual farms located in the north-eastern region of Poland. The samples of human milk (n = 20) were collected from women aged: 21–37, in the 2nd-4th month of lactation.The fatty acid composition was determined after the acids were transformed into methyl esters according to the IDF Standard method and gas chromatography using a Hewlett-Packard 6890 gas chromatograph with flame ionization detector. The average share of saturated FA (ΣSFA) in sheep, goat and cow milk fat were 77.5%, 75.5% and 67.7%, respectively, while in human and mare milk fat this value was about 47.0% ΣSFA. Human milk fat was characterized with the highest share of monounsaturated FA (ΣMUFA) 43.6%, while in the fat of other mammals this value was from 19.0 to 31.0%. The highest share of polyunsaturated FA (ΣPUFA; 22.0%) was found in mare milk. In human milk fat the value of ΣPUFA were higher (10%), than in milk of other mammals (3–5%). The lowest value of ΣSFA was observed in human and mare milk which could influence its health-promoting properties. The high share of other essential unsaturated FA indicates high dietary value of human milk. The share of fatty acids in mare milk similar to that in human milk makes it the most suitable in human nutrition.
