“…Casein is the major component of milk protein. In this work, α-casein, β-casein and soybean proteins showed profiles similar to other studies 18,20,21 with approximately 24 kDa and 32 kDa for α-casein and βcasein, respectively. Bands of higher intensity for raw sheep, UHT cow, raw cow and UHT goat were in the molar mass range of 32 kDa.…”

A screening method for zinc levels in different milk samples (raw cow, raw sheep, UHT cow, UHT goat and soybean milk base) was performed to establish the Zn levels’ differences in protein samples. The samples were digested in a cavity microwave oven and the total Zn levels in the extracts were determined by flame absorption atomic spectrometry (FAAS). The protein separation was performed by urea polyacrylamide gel electrophoresis (UREA-PAGE). Protein bands were digested in the cavity microwave oven and Zn-protein analysis was further conducted by electrothermal atomic absorption spectrometry (ETAAS). The results showed that Zn is mainly bound to 32 kDa (β-casein) protein (17.0 ± 2.0%) in UHT cow and 24 kDa (α-casein) protein (9.0 ± 0.6%) in raw sheep milk. This method provided quantitative information regarding Zn species present in the protein fractions of the milk samples. The accuracy was evaluated using certified reference material (whole milk powder, NIST 8435) with statistically equivalent concentrations (Student’s t-test) for total Zn and by addition and recovery experiments applied to measure Zn-protein. The recovered values were in the 92-110% range.

“…Regarding proteins, while total caseins and κ-casein in camel's milk are lower, β-casein is higher than in cow's milk. Camel's milk is rich in whey proteins such as immunoglobulins, lactoferrin, lysozyme, α-lactalbumin, and serum albumin, but lacks β-lactoglobulin when compared to whey proteins in cow's milk (Maqsood et al, 2019).…”

“…Therefore, camel's milk and its products' properties make it promising and attractive for future industry investment (Mohamed et al, 2014). Most recent studies that have focused on the compositional properties and functions of camel's milk and microbiological quality analyzed milk from camels in Arabia (El-Hatmi et al, 2015;Konuspayeva et al, 2014;Sesh et al, 2012;Akbar, 2015;Yadav et al, 2015;Maqsood et al, 2019;Nagy et al, 2019) and a few are in other countries (Omar et al, 2010;Zhao et al, 2015). In Turkey, however, to the best of our knowledge, no work has been conducted on camel milk's gross composition, minerals and sugars.…”

“…Industrial technology for producing livestock products involves the constant adaptation of animals to the effects of various adverse stress factors caused by conditions of keeping, feeding, exploitation [6][7][8][9]. The most pronounced negative effect of such factors is exerted on pregnant cows, in the body of which increased energy consumption occurs, caused by intensive exploitation and development of the fetus [10,11], which leads to the intensive use of plastic tissue compounds, primarily deposited fat, and hereinafter, structural lipids [4,12,13].…”

“…Mobilization of fatty acids occurs in complex oxidation reactions with carbohydrates and is often disrupted due to the relative lack of the latter. In this connection, under-oxidized compounds enter the bloodstream leading to depletion of the animal organism, vitamins, bioantioxidants arising due to high physiological load, stress, errors in feeding, which creates favorable conditions for the activation of nonenzymatic lipid oxidation [3,5,7,[12][13][14][15] which adversely affect the state of metabolism, and therefore the reproductive function of animals [16].…”

The purpose of the research is to determine the etiopathogenesis of reproductive dysfunction in highly productive cows. For this, one group of cows was formed on the principle of paranalogs in the amount of 37 animals inseminated in the first sexual hunt after calving, followed by taking blood samples from them using the Monovet system, considering the duration of pregnancy. During the start-up period, blood was taken 1–4 days before calving and on the first day after calving. A total of 253 blood samples were examined. Subsequently, depending on the effectiveness of insemination, animals were divided into two groups. The first group included inseminated cows after the first insemination (20 animals), the second group included 17 unfertilized cows after the first insemination. Subsequently, blood was taken from animals considering the course of childbirth and the postpartum period. Blood counts were studied according to generally accepted methods using certified equipment. The study found that at an early stage of pregnancy, cows have a significant difference in lipid metabolism and in their peroxidation, in the state of antioxidant systems compared to unstable animals. In the process of pregnancy development in cows, there is a decrease in the level of total lipids and their class, and the accumulation of products of transoxidation of lipids is reduced. In animals with retention of the placenta, a low lipid metabolism and a higher level of peroxidation were established already in the dry period. After calving, this difference increases. The obtained data can be used to develop an algorithm for the prevention of postpartum complications in cows by using substances with antioxidant properties.
