Abstract Fatty acid profile of beef subcutaneous fat was evaluated in two separate studies where blends of essential oils and/or benzoic acid were fed to finishing steers. Study 1 had sixty-eight finishing steers that were fed 1 of 5 finishing diets: no additional supplement, monensin/tylosin, essential oil blend #1 (Victus Liv, DSM Nutritional Products), benzoic acid (VevoVitall, DSM Nutritional Products), or a combination of essential oil blend #1 and benzoic acid. Study 2 had seventy-six finishing steers that were fed 1 of 7 finishing diets: no additional supplement, monensin/tylosin, essential oil blend #1, essential oil blend #2 (Fortissa Fit 45, Provimi Canada), benzoic acid, a combination of essential oil blend #1 and benzoic acid, or a combination of essential oil blend #2 and benzoic acid. All feed additives were supplemented according to manufacturer instructions, which were 33 mg/kg of monensin, 11 mg/kg of tylosin, 1 g/steer/day of essential oil blend #1, 4 g/steer/day of essential oil blend #2, and 0.5% inclusion level (on a DM basis) of benzoic acid. Fatty acid profile was determined on a 4 cm × 1 cm × 1 cm sample of subcutaneous fat from the 12th rib location of each steer. Fatty acid methyl esters were used to identify and quantify individual fatty acids using gas chromatography. Data were analyzed separately for the two studies, using a RCBD with fixed effect of treatment, and random effects of block (allocation weight of the steers) and the interaction of treatment and block. Total saturated fatty acids (SFA), total monounsaturated fatty acids (MUFA), total polyunsaturated fatty acids (PUFA), MUFA:SFA, PUFA:SFA, and n6:n3 were not different (P > 0.09) between treatments for either study. Overall, it was concluded that supplementation of essential oils and/or benzoic acid did not affect fatty acid profile of beef subcutaneous fat.

Abstract This study examined the effects of feeding two different commercially available blends of essential oils with or without benzoic acid on growth performance, carcass characteristics, and meat quality of finishing steers. Angus-based crossbred steers (N = 76; allocation BW = 429 ± 30 kg; starting BW = 466 kg ± 31 kg) were assigned by allocation weight into two blocks. Within each block, steers were randomly assigned to one of seven dietary treatments for a 100 d finishing period. Treatments were: 1) a negative control with no additives; 2) a positive control with supplementation of monensin/tylosin; 3) essential oil blend #1 (Victus Liv, DSM Nutritional Products); 4) essential oil blend #2 (Fortissa Fit 45, Provimi Canada); 5) benzoic acid (VevoVitall, DSM Nutritional Products); 6) a combination of essential oil blend #1 and benzoic acid; and 7) a combination of essential oil blend #2 and benzoic acid. All feed additives were supplemented at dosage levels according to manufacturer instructions. Growth performance, carcass characteristics, and meat quality were evaluated. Individual animal feed intake was collected using an Insentec feeding system, therefore steer was the experimental unit for all analyses. Data were analyzed using a RCBD with fixed effect of treatment and random effect of block. Final BW, ADG, DMI, and G:F were similar (P > 0.25) among treatments. There were no treatment differences (P > 0.15) for the carcass characteristics or the meat quality parameters evaluated in this study. Overall, steers supplemented with the commercial blends of essential oils with or without benzoic acid had similar growth performance, carcass characteristics, and meat quality parameters as steers fed CON or M/T, indicating that these products may have potential as replacements for monensin and/or tylosin.

Extracts and essential oils from seeds as well as essential oils from cone scales and needles with twigs of the Abies koreana population were studied. An analysis of Korean fir essential oils allowed us to determine 147 volatile compounds. The identified compounds constituted 97–99% of the seed, cone and needle oils. The main volatile in the seed and needle oils was limonene (56.6% and 23.4%, respectively), while the predominant volatile in cone oils was α-pinene (51.2%). Korean fir seeds provided a rich source of both essential oil (3.8–8.5%) and extract, which was isolated with a 24.5% yield and contained numerous groups of fatty acids and phytosterols (414 μg/100g extract). The most prominent fatty acids were unsaturated, among which linoleic (41.2%) and oleic (31.2%) fatty acid were the main ones while the dominant sterols were isomers of ergostadienol and β-sitosterol. A. koreana seeds, cones and needles are a source of many volatile bioactive compounds while the seed extract, with a pleasant scent, contained not only volatiles, but also fractions rich in fatty acids and phytosterols. These facts make A. koreana essential oils and especially the seed extract potential components of cosmetics.

Trial Duration

The aim of this experiment was to test the hypothesis that conjugated linoleic acid (CLA) in diets of finishing pigs fed linseed can improve the quality and oxidative stability of meat and subcutaneous fat. Twenty-four Prestice Black-Pied pigs (barrows and gilts) were divided into three groups and were fed a basal diet and diets supplemented with ground linseed (70 g/kg), or linseed combined with conjugated linoleic acid (20 g CLA-oil/kg). The trial duration was 53 days. Measurements included slaughter and meat quality parameters, oxidative stability determination, and fatty acid profile of meat and subcutaneous fat. The experimental data were analysed using one-way analysis of variance. Neither linseed nor linseed with CLA significantly influenced weight gain, lean percentage, muscle depth, backfat thickness, drip loss, meat shear force, dry matter, intramuscular fat or cholesterol (P > 0.05). Dietary supplementation with linseed increased the percentage of linolenic acid in the fatty acids of meat and backfat and resulted in higher production of aldehydes. Dietary CLA did not influence the susceptibility of lipids to oxidation. Supplementation with CLA significantly increased CLA proportions in fatty acids of meat and backfat, reduced proportions of monounsaturated fatty acids, and increased proportions of saturated fatty acids in backfat (P < 0.05). The concentration of CLA (in mg/100 g of fresh tissue) in backfat was almost fifty times higher than in meat. Both meat and backfat of pigs fed CLA-free diets contained CLA, probably as a result of microbial conversion of linoleic acid in the intestine. It can be concluded that CLA changed the fatty acid profile of meat and backfat, but did not improve oxidative stability and other meat quality traits of pigs fed linseed.

The objective of this study was to determine the chemical composition, fatty acid profile, and values of healthy indices of milk from a specialized farm of Polish Coldblood mares of different ages, birth orders, and lactation stages. Milk samples (n = 48) were collected for analysis in weeks 10, 15, and 25 of lactation from mares aged between five and 14 years. The study showed that the stage of lactation has a significant effect on the fatty acid (FA) profile of the milk produced on the farm. The highest concentration of monounsaturated and polyunsaturated FAs was found in milk produced from the 15th week of lactation. The milk was also characterized by low values of atherogenic and thrombogenic indices, which indicate the health benefits of milk with respect to the content of fatty acids and their potential to prevent or cause atherosclerosis and thrombosis. The study also found a significant correlation between the number of foalings (birth order), the fatty acid profile, and atherogenic index of milk produced on the farm. The findings from the study indicate that it is possible to modify the fatty acid profile of bulk tank milk through appropriate management of the age structure of the herd of mares. To confirm this dependence, the study will be continued on a larger group of mares.

The aim of this research was to determine fatty acid profiles in piglet brain, skin, and muscle, and in the milk of sows fed fat with different saturation grades during gestation and lactation. At 42 days of gestation, 50 multiparous sows were randomly allocated to one of two treatments, namely a diet containing pork lard (n = 25) and a diet containing soybean oil (n = 25). The fats were provided at 3.6% during gestation and at 4% during lactation. The experimental diets were offered through the weaning of the piglets. The fatty acid profile of the milk was determined fourteen days after parturition. At weaning (21 days postpartum) and seven days later, one of the piglets (n = 64) from 16 sows allocated to each treatment was selected at random to determine fatty acid profiles in brain, skin and muscle. Saturated and monounsaturated fatty acids were higher in the diet with pork lard than in that with soybean oil, in which the polyunsaturated fat content was higher. A higher saturation of fatty acids was found in milk from the sows that consumed pork lard, which contained more saturated fatty acids than the milk from sows that consumed soybean oil. The fatty acid profiles in muscle and skin of the piglets were affected by the diet of the sows. However, the fatty acid profile of the piglets’ brains was not affected by the diet of their mothers.
