SummaryTwo breed comparisons were made: (a) between Galway and Galway x Finnish Landrace (Fingalway) lambs, and (6) between Galway x Fingalway and Galway x (Finn x Texel) lambs, for the melting point and fatty acid composition of subcutaneous tail, subcutaneous 13th rib and perinephric fat. The lambs were slaughtered at market weight from September to January, being finished off on grass except for a small number finished indoors on concentrates and hay.Slaughter age and carcass weight, both of which had significant effects on some of the measurements, were included as covariates in the breed comparisons. Overall breed effects were small. The melting point of the fat from Fingalway lambs was lower than that of the Galway breed in each location, the difference being significant for subcutaneous rib fat. This was associated with a lower concentration of stearic acid and a higher concentration of oleic acid in each fat depot of the Fingalway breed, the difference being significant for oleic in subcutaneous tail and for stearic in subcutaneous rib fat. No significant breed differences or trends were observed for the other fatty acids measured. Results for a small number of pure Finn lambs supported the Finn ancestry influence indicated by comparison (a). In the second breed comparison, no significant breed differences were observed, the values being close to those obtained for the pure Galway lambs.

The Difference

The fatty acid and antioxidant property of pawpaw coconut oil (PCO) and virgin coconut oil (VCO) were compared. GC and GC-MS were used to determine the fatty acid of PCO and VCO, respectively. The results show that there is no obvious difference of fatty acid composition between PCO and VCO. The scavenging rate to ABTS+• of PCO is higher than VCO at the same proportion. TEAC (Trolox equivalent antioxidant capacity) value of PCO is 67.5µmol/l. The complexing ability to Fe2+of PCO is stronger than VCO at the same proportion. The scavenging ability to DPPH• of 40% PCO is weaker than VCO, with the increase of PCO concentration, the difference of the scavenging ability to DPPH• between PCO and VCO is smaller.

Fatty Acid Compositions

Twenty plant-derived and 18 non-plant-derived strains of Lactobacillus casei were compared for their growth in tryptone – yeast extract – glucose broth containing 0.3% bile by measuring absorbance at a wavelength of 620 nm after 24 h of incubation at 37 °C. Bile tolerance — a fundamental probiotic property — was calculated by dividing the experimental data by control values (growth without bile). We found that bile tolerance was strain specific but that the average bile tolerance of the plant-derived strains was significantly (P < 0.05) lower than that of the non-plant-derived strains tested. All tested strains could not deconjugate sodium taurocholate, indicating that the difference in bile tolerance was not due to the ability to deconjugate bile. The fatty acid compositions of the test strains with and without exposure to 0.3% bile were investigated, and a statistical correlation analysis between these compositions and their bile tolerance was conducted. The fatty acids correlated with bile tolerance differed between plant and non-plant lactobacilli. This is the first report to show that the origin (i.e., growth environment) of lactobacilli affects their fatty acid composition, which in turn, appears to be related to their bile tolerance.

The study was conducted in order to determine how the slaughter age (SA) and muscle type (MT) affect technological properties and fatty acid composition (FAC) of meat among Linda geese reared under the breeder conditions. A total of 16 male geese were slaughtered in order to determine the technological properties and FAC of meat. It was determined that the effect of SA on pH15 and pH24 (TM), water holding capacity (WHC), cooking loss (CL), and drip loss (DL) of the thigh muscle was all statistically significant (P < 0.05). The effect of SA on pH24, WHC, CL, and the 168th-hour DL of pectoral muscle (PM), was statistically significant (P < 0.05). Moreover, the effect of MT on pH15, pH24, WHC, CL and DL in the 12th week and on pH15, pH24, WHC and DL in the 16th week was found to be statistically significant (P < 0.05). Additionally, the effect of SA on monounsaturated fatty acid (ΣMUFA) of TM and polyunsaturated fatty acid (ΣPUFA) of PM and Σω-6 ratios was statistically significant (P < 0.05). Consequently, it was concluded that SA was better in the 12th week than the 16th week and PM was better than TM. The 16-week TM was better in terms of ΣMUFA, the 12-week PM was better in terms of ΣPUFA and Σω-6, and the 12-week TM was better in terms of Σω-3 amount and ω-6/ω-3 ratio. Therefore, it can be recommended that 12-week-old Linda geese be selected in terms of selected meat traits and FAC of meat.

AbstractEven though the sunflower is the second most widespread oil plant in the Czech Republic, there is a lack of information about the effects of climate, nitrogen and micronutrients application on sunflower oiliness and fatty acid composition of sunflower achenes. To obtain such information, we established five year experiment (2008–2012) to study the effect of climate, nitrogen (C-control, N 60–60 kg N ha−1, N 90–90 kg N ha−1, N 120–120 kg N ha−1) and of foliar application of boron (N 90 + B), zinc (N 90 + Zn) and molybdenum (N 90 + Mo) on sunflower oiliness and composition of fatty acids (palmitic, palmitoleic, stearic, oleic and linoleic acids). According to our results, oiliness and fatty acid composition was significantly influenced by climate and fertilizer treatment. Oiliness was influenced mainly by climate (96.4%), the effect of fertilizer treatment was minor (2.5%). Within the frame of climate, the effect of precipitation was slightly higher than of temperature. A strong and negative relationship between the dose of nitrogen and oiliness was revealed (r = –0.79), the difference between C and N 120 treatment was 2.1% on behalf of C treatment. The highest oiliness was recorded in 2011 (50.72%) and in C treatment (48.48%). The fatty acid composition was not significantly influenced by fertilizer treatment, but was significantly influenced by the climate conditions of the year. Application of micronutrients was not connected with any significant increase in oiliness or in the fatty acid composition due to a high initial content of those micronutrients in top soil.
