The aim of our study was to evaluate the gradient of milk yield, of milk biochemical composition and fatty acids profile according to breed, for primipara goats from Carpathian breed and Saanen x Carpathian and French Alpine x Carpathian half breed that were grown in semi-intensive system (Dobrogea, South Romania). The studies were performed on goats raised at ANCC CAPRIROM farm, located in Constanta, Romania. The biochemical parameters (fat, proteins, lactose) were studied by electrochemical method with a Lactostar analyzer Funke Gerber type specialized for goat milk. Milk fatty acids profile, as fatty acids methyl esters (FAME), was determined by chromatographically gas method. The considerable high protein content found in half breeds, might be explained by the fact that bucks from specialized breeds such us Saanen and French Alpine which were used for half breeding, come from imported animals from France, which were locus genotyped for alpha S1 casein gene and were selected dominant genotypes that lead to a higher protein concentration in milk.The statistical analysis shows that the milk coming from Carpathian does and their half breeds is not significantly different regarding the levels of various fatty acids, saving omega 3 acids, which are considerable higher at Carpathian does, proving that food has the decisive role regarding composition.

Abstract The objective of this study was to investigate whether dietary supplementation with different polyunsaturated fatty acids (PUFA s) affects expression of genes related to somatotropic axis and the plasma concentrations of insulin, glucose, non-esterified fatty acids (NEFA), beta hydroxyl butyrate acids (BHBA) and insulin-like growth factor 1 (IGF1) and milk fatty acids profile. Right after calving, Holstein cows (n=45) were randomly assigned to one of three diets supplemented with roasted whole soybean as a source of omega-6 PUFA (omega-6, n=15), linseed as a source of omega-3 PUFA (omega-3, n=15) or palm oil (control, n=15). Each cow was in the study over a period of 70 days. Blood samples were collected every two weeks from day 1 to 70 of lactation and plasma concentrations of insulin, glucose, NEFA, BHBA and IGF1 were determined. Liver samples were taken from a subset of 18 cows (6 per diet) at day 70 postpartum and hepatic mRNA level of total growth hormone-receptor 1A (GHR1A), insulin receptor (INSR), IGF1 and insulinlike growth factor binding protein (IGFBP2) was assessed. Experimental diets did not affect milk yield. Plasma glucose and insulin concentrations were greater for omega-3 treatment compared to omega-6 and control treatments. Cows fed diets enriched in omega-3 exhibited greater INSR and GHR1A mRNA expression, and a tendency for greater IGF1 mRNA expression in the liver compared to omega-6 and control cows. Plasma IGF1 concentration was significantly higher in omega-3 treatment compared with omega-6 and control treatments. Results of this study suggest that feeding omega-3 PUFA s during early postpartum couples with the somatotropic axis, leading to an increase in plasma IGF1 concentration in dairy cows.

The aim of the present study was to characterize the fatty acids profile and the related health lipid indices of goat`s milk from different Bulgarian breeds in order to add information on its nutritional quality. The study was performed with goat milk from a private farm in the Stara Planina Mountain. Milk samples were collected from three breeds – Bulgarian White Dairy Goat, Toggenburg and local goats. The content of saturated fatty acids was the highest in the milk of the local breed – 83.6% compared to for Bulgarian White Dairy Goat - 75.4% and Toggenburg - 75.2%. The atherogenic index was calculated on the obtained values for lauric (C12:0), myristic (C14:0) and palmitic (C16:0) acids and the unsaturated fatty acids. The data for the Bulgarian White Dairy Goat was – 3.12; Toggenburg – 3.14 and for local breed – 5.54. The values of the atherogenic index showed that it is the lowest for the Toggenburg, following Bulgarian White Dairy Goat and local breed. Omega 6/Omega 3 ratio varies from 1.58 for local breed to 2.44 for Toggenburg which is within the range of the optimal values for healthy nutrition.

Stearoyl Coa Desaturase

The effect of pasture on the stearoyl-CoA desaturase (SCD) and miRNA 103 expression was evaluated on dairy goats divided into two homogeneous groups (G, grazing, and S, stable). Group S was housed in a stall and received alfalfa hay as forage, while group G was led to pasture. The goats of both the groups received the same amount of concentrate. Milk yield did not differ statistically between the groups. Group G showed significantly higher fat (4.10% vs. 2.94%, p < 0.01) and protein percentage (3.43% vs. 3.25%; p < 0.05) than group S. Among milk fatty acids, group S showed significantly higher levels of saturated fatty acids (SFA) and lower values of mono-unsaturated fatty acid (MUFA). The percentages of polyunsaturated fatty acid (PUFA) were not different between groups even if pasture significantly affected the percentages of C18:3 and total omega 3. In group G, total CLAs were twice than in group S (0.646% vs. 0.311%; p < 0.01) mainly due to the differences in CLA cis9 trans 11 (0.623% vs. 0.304%; p < 0.01). Milk total CLA in grazing group was significantly (p < 0.01) higher in August according to the highest value of both linoleic and α-linolenic acids in the pasture. In grazing animals, SCD expression decreased from April to June, increased in July and decreased again in August, while it was almost unvaried along the trial in group S. By contrast, the expression of miRNA 103 showed a similar trend for both groups, decreasing from April to June, increasing in July and falling down in August. To our knowledge, this is the first observation of the effects of pasture on miRNA expression in milk from ruminant species.

The Impact

Milk contains several important nutrients that are beneficial for human health. This review considers the nutritional qualities of essential fatty acids (FAs), especially omega-3 (ω-3) and omega-6 (ω-6) polyunsaturated fatty acids (PUFAs) present in milk from ruminant and non-ruminant species. In particular, the impact of milk fatty acids on metabolism is discussed, including its effects on the central nervous system. In addition, we presented data indicating how animal feeding—the main way to modify milk fat composition—may have a potential impact on human health, and how rearing and feeding systems strongly affect milk quality within the same animal species. Finally, we have presented the results of in vivo studies aimed at supporting the beneficial effects of milk FA intake in animal models, and the factors limiting their transferability to humans were discussed.

Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are commercially important omega-3 fatty acids found in fish oils. Here we demonstrate that a handheld Raman spectrometer can be used to quantitate these compounds in intact fish oil capsules, avoiding oxidizing risk. Partial least squares regression models were prepared by relating Raman spectral variance to EPA and DHA concentrations determined using gas chromatography–mass spectrometry (GC-MS) analysis of fatty acid methyl esters in 15 commercial samples containing 145–473 mg g−1 EPA and 101–260 mg·g−1 DHA. Handheld Fourier transform (FT)-Raman models had root mean square errors of cross-validation of 38 mg g−1, 24 mg g−1, and 32 mg·g−1 for EPA, DHA, and EPA+DHA, respectively. Models generated from a benchtop FT-Raman spectrometer had corresponding errors of 32 mg·g−1, 22 mg·g−1, and 26 mg·g−1. By comparison, average standard deviations from triplicate GC-MS analyses were 11 mg·g−1 for EPA and 9 mg·g−1 for DHA.

Abstract Lauric acid (LA) is an additive used in ruminant’s diet with the purpose of mitigating the methane effect. However, the presence of a certain amount of LA in the rumen can cause a reduction in the microbial population and ruminal metabolic processes, such as the biohydrogenation. This study aimed evaluate the effect of the LA inclusion in the diet of Nellore on the fatty acids profile of the meat. Thirty-two young Nellore bulls were used with an average age of 24-months. The animals were individually fed with a total mixed ration with 40% of roughage (Cynodon sp. hay) and 60% of concentrated mix, composed with ground corn, soybean meal, urea, mineral premix and LA in 0.0; 0.5; 1.0; 1.5% of inclusion in the total diet dry matter basis. Those amounts constituted the treatments. At the end of the trial, the animals were slaughtered and the meat was stored at -21oC, before analyses. The experimental design was completely randomized, with four treatments and eight replications. The data were submitted to regression analysis, and significance was declared when P &lt; 0.05. There was no effect (P &gt; 0.05) of the inclusion of LA in the sum of saturated fatty acids (∑SAF=43.45±1.55), monounsaturated fatty acids (∑MUFA=41.9±0.29), and polyunsaturated fatty acids (∑PUFA=12.25±1.40). The inclusion of LA in the diets also did not affect the sum of omega-3 fatty acids (∑ n-3=1.05±0.22), omega-6 fatty acids (∑ n-6=3.02±0.49, and the reason n-6: n-3 (2.91±0.12). The atherogenicity (0.65±0.05) and trombogenicity (1.47±0.10) indexes, important indexes to predict heart coronary diseases risk, were not affected by the inclusion of LA in the diet of the animals. The results suggest that LA can be included up to 1.5% (DM basis of total diet) in the diets of Nellore without causing any significant changes in the fatty acids profile of the meat.

The objective of this study was to determine the chemical composition of five different food seeds (sunflower, poppy, hemp, flax and sesame) regarding fatty acid, mineral (Fe, Cu, Zn, Na, Mg, K, Ca, Al) and protein content. In addition, the total antioxidant capacity of the seeds was evaluated using the photochemiluminescent assay. The food seeds were subjected to lipid extraction and converted into fatty acid methyl esters before the gas chromatography analysis. In all food seeds, the saturated (SFAs), monounsaturated (MUFAs) and polyunsaturated fatty acids (PUFAs) were identified, respectively. PUFAs were the most abundant fatty acids (61.2% ± 0.07% and 84.8% ± 0.08% of total fatty acids), with the highest content in flax and hemp seed oil. Also, high amounts of omega-3 from PUFAs were determined in flax and hempseed oil. Based on the obtained results the sunflower, sesame and poppy seeds are good sources of omega-6, while flax and hemp seeds are good sources of omega-3. All samples are rich in minerals (Na, K, Ca, Mg) and have more than 20% protein content.
