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.

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 < 0.05. There was no effect (P > 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.

AbstractThe oil of amaranth grain (Amaranthus spp.) is a rich source of poly-unsaturated fatty acids. In this study, we tested 10 amaranth samples representing two species (Amaranthus cruentus and Amaranthus hypochondriacus) in two consecutive years (2010, 2011). Grain oils were analysed by gas chromatography for their fatty acids profile. In 2010, oil content ranged from 6.4–8.2% for A. cruentus and 6.3–7.9% for A. hypochondriacus. In 2011, the level was 7.1–8.2% and 6.6–8.7% for A. cruentus and A. hypochondriacus, respectively. Linoleic, palmitic, and oleic acids were dominant fatty acids in all of the oil samples. The essential linoleic acid level was 33.3–38.7% (A. cruentus) and 31.7–47.5% (A. hypochondriacus) in 2010 and 34.6–39.9% (A. cruentus) and 34–44.5% (A. hypochondriacus) in 2011. The minority fatty acids, i.e. stearic, α-linolenic, and arachidic acids were also observed. Eicosenoic and behenic acids were present in the grain in trace amounts. Statistical evaluation showed a significant effect of year and species of amaranth on the levels of certain fatty acids. There was a strong positive correlation between oil content and oleic acid, and a negative correlation between oleic acid and either of the other two fatty acids, linoleic and α-linolenic ones.

The performance characteristics of the engine and the emission levels with Copra Oil (CPO), Virgin Coconut (cocos nucifera) Oil (VCO), Tamanu (calaphyllum inopyllum) Oil (TMO), and Nangae (canarium indicum) Oil (NGO) are presented. The oils, obtained from naturally grown trees in Vanuatu, were tested as straight vegetable oils (SVOs) in a Diesel engine and the results are compared with those of neat diesel. The oils were converted to their fatty-acid-methyl-esters (FAMEs) using gas chromatography to determine their fatty acid compositions. The brake thermal efficiency with SVOs was found to be comparable to diesel. The structure of the alkyl chain and the carbon-to-hydrogen ratio were also studied. All the oils have Palmitic acid, Capric acid, Caprylic acid, and Oleic acid as the major fatty acids. The CPO and VCO have higher amounts of Oleic acid, which acts as an additive and breaks up the interaction between the major fatty acids at higher temperatures, reducing the viscosity. Emissions of CO2 were lower while those of CO, NOx, and SO2 were higher with SVOs compared to diesel. The results indicate that the local SVOs are good and inexpensive substitute fuels for Vanuatu that can help the country meet the UN’s sustainable development goals.

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.

Oil extraction from Cashew nut was carried out by Soxhlet method using n-hexane as the solvent. The oil was transesterified to produce Fatty Acid Methyl-Esters (FAMEs) and glycerol. Fenugreek and Moringa seed oils were purchased from the market. GC- Analysis gave the following fatty acids composition: Oleic (74.99%), Linoleic (1.27%), Stearic (2.09%), Myristic (0.86%), Lauric (1.97%), Linolenic (1.75%), Palmitic (12.51%) and Palmitoleic (2.70%) for Moringa oil; Oleic (67.62%), Linoleic (16.99%), Stearic (8.42%) and Palmitic (6.93%) for Cashew oil while Fenugreek oil constituted of Oleic (20%), Linoleic (42.5%), Stearic (6.5%), Linolenic (18%), Palmitic (10.5%) and Arachidonic (0.5%). The study revealed that the three vegetable seeds are good sources of edible oils. Cashew oil is considered to be the most suitable for food formulation as well as pharmaceutical, paint, soap and perfume industries because of high level of unsaturated in the fatty acid contents.
