“…Yak milk is the ideal source of raw milk to be processed into cream and its products [ 25 ]. Compared to butter from cow, sheep and goat, butter from yak has higher contents of conjugated linoleic acid, monounsaturated fatty acids, oleic acid, and n-3 long-chain polyunsaturated fatty acids and the lowest content of saturated fatty acids [ 26 ]. Under the same feeding conditions, cattle x yak hybrid milk yield is significantly higher than that of yak, but the milk fat and dry matter content of cattle x yak hybrid milk are lower than that of yak milk [ 27 ].…”

The Jeryak is the hybrid offspring of yaks and Jersey cattle and exhibit improved milk and meat yields. Biomolecules carried within milk exosomes are important for cell growth, development, immune regulation, and various pathophysiological processes. Previous studies showed that miRNAs regulate mammary gland development, lactation, and milk quality. This study explored the relationship between milk exosomes miRNAs and lactation performance. A comparison of the milk content showed that yak milk was of a better quality compared to Jeryak milk (casein, fat, TS, SNF, lactose). Milk collected in December was superior to that collected in June for both yak and Jeryak, except for lactose concentrations. Exosomes were extracted by density gradient centrifugation and miRNA expression profiles in milk exosomes from three yaks and three Jeryaks collected in June and December were detected by small RNA sequencing. In all, 22, 120, 78, and 62 differentially expressed miRNAs (DEMs) were identified in Jun_ JY vs. Jun_ Y (P1: Jeryak in June vs. Yak in June), Jun_ JY vs. Dec_ JY (P2: Jeryak in June vs. Jeryak in December), Dec_ JY vs. Dec_ Y (P3: Jeryak in December vs. Yak in December), and Jun_ Y vs. Dec_ Y (P4: Yak in June vs. Yak in December) groups. These DEMs were enriched in functions and signaling pathways related to lactation performance. In conclusion, these findings are a reference tool to study the molecular basis of lactation performance.

“…Among dairy products and dairy fats, yak butter was reported as a valuable dietary source of CLA, four times higher than other kinds of butter, and has been associated with anti-carcinogenic, antihypertensive, and anti-atherosclerotic actions, as well as with inhibiting the development of osteoporosis [68]. Compared to other essential FAs, CLA can act as a strong antioxidant and is able to effectively protect structural lipids against free radicals and different reactive oxygen species.…”

Essential Fatty Acids as Biomedicines in Cardiac Health

The destructive impact of cardiovascular diseases on health, including heart failure, peripheral artery disease, atherosclerosis, stroke, and other cardiac pathological conditions, positions these health conditions as leading causes of increased global mortality rates, thereby impacting the human quality of life. The considerable changes in modern lifestyles, including the increase in food intake and the change in eating habits, will unavoidably lead to an unbalanced consumption of essential fatty acids, with a direct effect on cardiovascular health problems. In the last decade, essential fatty acids have become the main focus of scientific research in medical fields aiming to establish their impact for preventing cardiovascular diseases and the associated risk factors. Specifically, polyunsaturated fatty acids (PUFA), such as omega 3 fatty acids, and monounsaturated fatty acids from various sources are mentioned in the literature as having a cardio-protective role, due to various biological mechanisms that are still to be clarified. This review aims to describe the major biological mechanisms of how diets rich in essential fatty acids, or simply essential fatty acid administration, could have anti-inflammatory, vasodilatory, anti-arrhythmic, antithrombotic, antioxidant, and anti-atherogenic effects. This review describes findings originating from clinical studies in which dietary sources of FAs were tested for their role in mitigating the impact of heart disorders in human health.

“…However, both milk types have a similar amino acid composition in protein. For years, yak milk has been used to produce ghee, butter, cheese, yoghurt and other fermented products, which have been a significant source of nutrients for individuals living, especially in high altitudes ( Agyare & Liang, 2021 ). Milk proteins have been reported to be a good source of bioactive peptides, which exert numerous health beneficial effects, such as antimicrobial, antiviral, antioxidant, antithrombotic, opioid, immunoregulatory, and antihypertensive activities ( Chourasia et al, 2020 , Chourasia et al, 2021 ).…”
