Randomized Experimental Design

To assess the influence of genotype and diets with different energy levels on the lipid profile of sheep meat, 54 lambs were used (18 animals from each genotype: Morada Nova, Santa Inez and ½Dorper + ½Santa Inez crossbred), distributed in a completely randomized experimental design in a 3 × 2 factorial arragement (three genotypes and two diets). The animals were submitted to two diets, 2.5 Mcal ME/kg DM and 3.0 Mcal ME/kg DM, receiving feed and water to reach the desired average live weight of 30 kg, when they were slaughtered. Total lipids, cholesterol, phospholipids and fatty acids profile of the Longissimus muscle were assessed. Diet and genotype did not influence the total lipids, cholesterol and phospholipids contents. The diet with the highest energy value presented higher values for the concentration of C12:0, C14:0, C18:0, C19:0, C22:0 acids and monounsaturated fatty acids (MUFA) in relation to that with the lowest energy value. However, for the concentrations of C15:0 acid and polyunsaturated fatty acids (PUFA), the highest values were recorded for diet with the lowest energy value. Genotype and diet influenced significantly the MUFA concentration, in which ½Dorper + ½Santa Inez crossbred genotype and diet with 2.5 Mcal ME/kg DM showed the highest values. Genotype influenced the saturated fatty acids (SFA) concentration, with ½Dorper + ½Santa Inez crossbred obtaining the lowest mean, behavior similar to that observed for PUFA concentrations. Desirable fatty acids (DFA), atherogenicity index as well as PUFA:SFA, MUFA:SFA, (C18:0 + C18:1):C16:0 ratios were influenced by diet and genotype. ½Dorper + ½Santa Inez crossbred and diet with 2.5 Mcal ME/kg DM obtained the best results.

Fatty acid profile and the related nutritional indices of the breast, thigh and drumstick muscles were studied at three farms, suppliers of ROSS 308 line of broilers, slaughtered at the age of 42 days. The proximate chemical composition of the commercial slaughter cuts revealed contents between 16.26�22.78% for proteins and 1.80�7.45% for total lipids, the breast having the highest protein and ash content and lowest values for fat and moisture. The obtained values were mainly affected by region (P[0.001). Meat fatty acid profile was affected (P[0.001) by commercial slaughter regions (CSR) and by the interactions between CSR and supplier farms (Farm A, B, and C) at different levels. The obvious findings highlighted that Farm B supplied broilers with a delivered higher content of beneficial fatty acids (LA, LNA, AA, EPA, and DHA) in breasts and drumstick, while for thigh, Farm C had the best results. The content of total saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (MUFAs) had the highest level in the thigh (P[0.001).

Worldwide, the food industry generates a large number of by-products from a wide variety of sources. These by-products represent an interesting and economical source of added value components with potential functionalities and/or bioactivities, which might be explored for industrial purposes, encouraging and promoting the circular economy concept. In this context, the current work aimed to evaluate the fatty acids (FAs) profile using gas chromatography–flame ionization detector (GC–FID) and Fourier Transform Infrared (FTIR), as well as the determination of related health lipid indices (e.g., atherogenic (AI) and thrombogenic (TI)) as a powerful strategy to investigate the potential applications of different agri-food by-products for human nutrition and animal feeding. This work results showed that polyunsaturated fatty acids (PUFAs) are the predominant group in grape pomace (72.7%), grape bunches (54.3%), and brewer’s spent grain (BSG, 59.0%), whereas carrot peels are dominated by monounsaturated fatty acids (MUFAs, 47.3%), and grape stems (46.2%), lees (from 50.8 to 74.1%), and potato peels (77.2%) by saturated fatty acids (SFAs). These findings represent a scientific basis for exploring the nutritional properties of agri-food by-products. Special attention should be given to grape pomace, grape bunches, and BSG since they have a high content of PUFAs (from 54.3 to 72.7%) and lower AI (from 0.11 to 0.38) and TI (from 0.30 to 0.56) indexes, suggesting their potential to provide a variety of health benefits against cardiovascular diseases including well-established hypotriglyceridemia and anti-inflammatory effects, products to which they are added.

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.

 Lipid contents and the composition of fatty acids of fillets from Chilean salmon (Salmo salar) were determined under different conservation methods: fresh salmon, frozen salmon, water-conserved canned salmon and frozen salmon in long-term storage. Fatty acid contents were determined by gas chromatography. The fillets had high lipid levels, ranging between 9.71 and 12.86%. All samples presented high levels of monounsaturated fatty acids, between 363.69 and 425.30 mg g-1 of total lipids, followed by polyunsaturated fatty acids (294.46 - 342.45 mg g-1 of total lipids) and saturated fatty acids (203.32 - 223.17 mg g-1 of total lipids). Although samples revealed different lipid contents, all proved to be great sources of omega-3 fatty acids, regardless of the manner of conservation.

The impacts of supplementing with whole oats grain (OG) upon performance and beef quality traits of growing steers grazing oats pasture (OP) were measured. The trial used Angus steer calves (203 kg mean bodyweight) assigned to three treatments: Control, unsupplemented OP (CON); OP plus OG fed at 0.25% BW daily (OG1); and OP plus OG fed at 0.50% bodyweight daily (OG2). All steers grazed the same paddock but were removed momentarily once daily so OG could be fed to each steer individually. Daily intake of OG averaged 597 and 1294 g DM for OG1 and OG2, respectively. Steers were slaughtered after grazing for 130 days to determine carcass characteristics and lipid profiles. In parallel with the grazing trial, four ruminally cannulated steers (613 kg mean bodyweight) were allocated to treatments CON and OG2 (n = 2) to monitor ruminal pH, volatile fatty acids, and NH3-N. Steers fed OG2 had greater (P < 0.01) average daily gain than CON; final liveweight for OG2 steers was significantly higher than both CON and OG1 steers. Although variations in plasma haematocrit and alkaline phosphatase were they did not affect animal performance. Dressing percentage was not affected by the experimental diets but OG2 steers had greater (P < 0.05) marbling scores. Although rib-eye area was numerically greater for OG1 and OG2 than CON steers (8% and 14%), these differences were not significant statistically (P = 0.3493). Intramuscular lipid content of Longissimus dorsi muscle was not significantly increased by OG supplementation but of the intramuscular fatty acids, contributions of vaccenic and α-linolenic acids decreased (P < 0.05). Linoleic acid content was lowest (P < 0.05) for OG1 steers. A no significant decrease in conjugated linoleic acid was detected when more OG was supplemented. No treatment differences in the contributions of eicosapentaenoic acid, docosahexaenoic acid, monounsaturated fatty acids, polyunsaturated fatty acids, saturated fatty acids, n-6 or n-3 to intramuscular fatty acids were detected although the n-6 : n-3 resulted numerically higher (11% and 23%) for OG1 and OG2 steers than CON steers. Rumen pH, NH3-N and volatile fatty acids were not significantly altered by OG supplementation. Supplementing diets of cattle grazing OP improved performance without rumen digestion impairs or inducing substantial changes in the lipid profile of intramuscular fat. Thus, OG supplementation would be expected to improve the efficiency of cattle grazing of OP without substantial changes to ruminal measurements or the lipid profile of beef.

ABSTRACT: This study was conducted to evaluate the effects of net energy levels on the lipid profile of adipose tissue and muscle of swines. A total of 90 animals, with initial weight of 71.94±4.43kg, were used, and distributed in a randomized block design in five net energy levels (2,300, 2,425, 2,550, 2,675, and 2,800Kcal kg-1 feed), with nine replicates and two animals per experimental unit. Lipid profiles of adipose tissue and muscle were analyzed using gas chromatography. Increasing the levels of net energy using soybean oil, improved the lipid profile of adipose tissue and muscle, increased linearly (P<0.05) the concentrations of polyunsaturated fatty acids, especially linoleic and α-linolenic acid, reduced linearly (P<0.05) the monounsaturated and saturated fatty acids and omega 6: omega 3. In adipose tissue was observed linear reduction (P<0.05) of atherogenic and thrombogenic indexes. In conclusion, increasing the level of net energy of the diet using soybean oil improved the lipid profile of adipose tissue and muscle.

Abstract. The aim of the experiment was to define the effect of a Suffolk-sired genotype on the chemical composition and fatty acid profile of the Quadriceps femoris muscle in fattened lambs reared under organic farming conditions. Three different genotypes of Suffolk-sired crossbreds were included in the experiment: F1 Suffolk-Charollais (SF 50 CH 50, n=10), F11 Suffolk-Charollais (SF 75 CH 25, n=10) and F1 Suffolk-Improved Walachian (SF 50 IW 50, n=10). The genotype did not have any effect on age at slaughter, average daily gain or carcass dressing percentages. However, the SF 75 CH 25 lambs displayed a lower live weight at slaughter (P<0.05), lower cold carcass weight (P<0.05) and lower protein content in muscle (P<0.05) than both of the other genotypes. They also had a lower content of kidney fat compared to the SF 50 CH 50 (P<0.01). The F11 Suffolk-Charollais lambs showed a higher proportion of C12:0 (P<0.01), C14:0 (P<0.01) and C16:0 (P<0.05) than the other two genotypes. A higher proportion of C18:0 was found in the SF 50 CH 50 lambs (P<0.05). The total content of saturated fatty acids (SFA) was higher in the SF 75 CH 25 crossbreds (P<0.05). The genotype also affected the content of C16:1 having its highest presence in the SF 75 CH 25 lambs while the lowest presence was found in the SF 50 CH 50 lambs (P<0.01). Between these two genotypes there were also found different proportions of C18:1 having its higher presence in SF 50 CH 50 lambs (P<0.05). Moreover, the IW type lambs had a lower SFA proportion and lower values of atherogenic and thrombogenic indexes and a higher polyunsaturated/saturated fatty acid (P/S) ratio in their meat than lambs of the CH genotypes (P<0.05). As for crossing between the Suffolk and Charollais breeds, a favourable fatty acids profile of meat was observed in the F1 crossbred as compared to the F11 crossbred.

AbstractMeat and meat products are one of the most relevant food groups in the human diet due to high content of protein. Meat from wild animals is considered a delicacy and commands a high price compared to other sorts of meat. Due to the characteristic sensory properties (taste), lower fat and cholesterol contents and higher share of polyunsaturated fatty acids (PUFA) a growing interest of this meat is noted(1,2).The aim of the study was to compare fatty acid profile in wild boars muscles depending on the feeding grounds.The research material consisted of 37 samples of wild boars (Sus scrofa) muscles from three different regions in Poland: Warmia and Mazury, Podlasie and Silesia. The fat was extracted from the muscle samples by the Folch method. The fatty acid (FA) composition was determined after the acids were trans-methylated according to the Peisker method. Chromatographic separation was performed using an Agilent Technologies 7890A gas chromatograph with a flame-ionization detector (FID).The average share of sum of saturated fatty acids (ΣSFA) in wild boars fat from Warmia and Mazury, Podlasie and Silesia regions were 41.5%, 39.6% and 38.8%, respectively. In wild boars fat from Silesia the highest share of sum of monounsaturated fatty acids (ΣMUFA) was found (46.9%), while in wild boars fat from Warmia and Mazury, Podlasie it accounted for: 44.4% and 39.9%, respectively. A similar share of ΣPUFA (approx. 14%) was determined in wild boars fat from Warmia and Mazury, and Silesia region, whereas in those from Podlasie region ΣPUFA accounted for approx. 12%.Meat fat from wild boars is a valuable source of fatty acids with a beneficial impact on human health. However, the fatty acids profile depends of the region, which indicated the predominant influence of the animal's feed on FA composition of meat fat.
