The aim of this study was to analyse the fatty acid (FA) profile of blood plasma at mating and 72 hpm by gas chromatography. Moreover, the correlation between FA and ovulation rate, normal embryos and compacted morulae was estimated. Palmitic, linoleic, oleic and stearic were the highest FA concentrations at mating and 72 hpm. Most long chain saturated and PUFA were higher at 72 hpm than at mating, while MUFA were higher at mating. SFA, MUFA and PUFA were high and positively correlated. Correlation was 0.643 between MUFA at mating and ovulation rate, and 0.781 between MUFA and normal embryos, respectively. Compacted morulae were slightly correlated with SFA at mating (0.465). In conclusion, the FA profile of plasma varies depending on the reproductive cycle of the rabbit female, adapting to energetic requirements at mating and early gestation. Moreover, positive correlations are found between fatty acids and ovulation rate and embryo development and quality.

AbstractDietary fatty acids and cholesterol content are proved, by many research studies, to be associated with various health conditions, including cardiovascular health. Knowledge of the composition of these nutrients in food is essential for proper planning of health programs. The present study aimed at assessing the fatty acid profile, fatty acid nutritional quality, and cholesterol composition of 37 foods commonly consumed in the State of Kuwait and the potential impact of these foods on cardiovascular risk. Fatty acid profile was determined by gas chromatography-flame ionization detector into four types: saturated, monounsaturated, polyunsaturated, and trans fatty acids. Nutritional quality was calculated using the atherogenic index, thrombogenic index, hypocholesterolemic/hypercholesterolemic fatty acid ratio, polyunsaturated fatty acid/ saturated fatty acid ratio, and n-3/n-6 fatty acids ratio. Determination of cholesterol was performed by gas chromatography. Saturated fatty acid levels ranged from 0.01–21.83, monounsaturated fatty acids 0.01–25.51, and 0.013–22.87 g/100 g edible portion of food. The predominant fatty acids identified in all studied foods were C18:2c (n-3), C16:0, and C18:1c, with values 0.45–56.52, 10.12–44.90, and 16.99–42.56% of total fatty acids, respectively. The trans fatty acid content was low in all foods. Cholesterol levels varied between traces (<0.05) and 454.79 mg/100 g edible portions of food. Results show that seafood, rice-based, seed-based, and vegetable-based foods had better nutritional quality in terms of the fatty acids content, as indicated by the polyunsaturated fatty acid/saturated fatty acid and n-3/n-6 ratios, low thrombogenicity indices, and high hypocholesterolemic/hypercholesterolemic fatty acid ratios. Cholesterol and fatty acid data obtained in the present study will be of special interest for many studies, including nutrition-related health research, and will help policymakers in proper strategies for health programs.

This experiment was conducted to determine the effects of diets supplemented with cottonseed oil,Acacia mearnsii-condensed tannin extract, and a combination of both on composition of bovine milk. Treatment diets included addition of cottonseed oil (800 g/d; CSO), condensed tannin fromAcacia mearnsii(400 g/d; TAN) or a combination of cottonseed oil (800 g/d) and condensed tannin (400 g/d; CPT) with a diet consisting of 6·0 kg dry matter (DM) of concentrates and alfalfa hay ad libitum, which also served as the control diet (CON). Relative to the CON diet, feeding CSO and CPT diets had a minor impact on feed intake and yield of lactose in milk. These diets increased yields of milk and protein in milk. In contrast to the TAN diet, the CSO and CPT diets significantly decreased milk fat concentration and altered milk fatty acid composition by decreasing the proportion of saturated fatty acids but increasing proportions of monounsaturated and polyunsaturated fatty acids. The CPT diet had a similar effect to the CSO diet in modifying fatty acid profile. Overall, reduction in milk fat concentration and changes in milk fatty acid profile were probably due to supplementation of linoleic acid-rich cottonseed oil. The TAN diet had no effect on feed intake, milk yield and milk protein concentration. However, a reduction in the yields of protein and lactose occurred when cows were fed this diet. Supplemented tannin had no significant effect on fat concentration and changes in fatty acid profile in milk. All supplemented diets did not affect protein concentration or composition, nitrogen concentration, or casein to total protein ratio of the resulting milk.

The aim of the study was to compare and demonstrate whether commercial rennet ripening cheeses available on the market in summer and winter differ in their chemical composition, fatty acid profile, content of cis9trans11 C18:2 (CLA) acid and other trans isomers of C18:1 and C18:2 acid and whether they are characterized by different values of lipid quality assessment indices. The experimental material consisted of rennet ripening of cheeses produced from cow’s milk available in the Polish market. The first batch contained cheeses produced in winter and purchased from the market between May and June. The second batch contained cheeses produced in summer and purchased between November and December. Chemical composition was analyzed by FoodScan apparatus. The gas chromatography (GC) method was used to determine the content of fatty acids. Results obtained in the presented study indicate that the chemical composition, content of fatty acids trans isomers, and lipid quality indices varied between summer and winter cheeses. The summer cheeses were richer sources of MUFA and PUFA compared to winter cheeses. Summer cheeses were also characterized by lower content of SFA, higher content n-3, lower n-6/n-3 ratio, and higher content of DFA. Higher contents of CLA and trans C18:1 and C18:2 were found in summer cheeses.
