This study aimed to evaluate the effects of supplementation with sunflower seeds and vitamin E for fattening lambs, on the chemical composition, cholesterol, vitamin E level, fatty acid profile and lipid oxidation of meat from sheep. Four treatments were evaluated, as follows: SC – basal diet consisting of sugarcane + concentrate; SCS – basal diet supplemented with sunflower seed; SCE – basal diet supplemented with 1000 mg vitamin E; SCSE – basal diet supplemented with sunflower seed and 1000 mg vitamin E. The Longissimus lumborum muscle of 32 Ile de France lambs, which were slaughtered when their bodyweight reached 32 kg, was used. The chemical composition of the lamb meat was not significantly different (P > 0.05) between the treatments. Sunflower seed supplementation increased (P < 0.05) the levels of linoleic acid, vaccenic acid and conjugated linoleic acid. Inclusion of vitamin E in the diet increased (P < 0.05) the concentration of vitamin E in the meat while decreasing lipid oxidation. Considering the current demand for healthy foods, inclusion of sunflower seeds and vitamin E in the diet of sheep is a viable possibility.

Eight cows in mid-lactation were used to determine the effects of feeding diets containing soybeans (SBS) or sunflower seed (SFS) on conjugated linoleic acid (CLA) yield and concentration in milk during two 3-wk periods. All cows were fed a standard pre-trial diet for 2 wk, before assignment to treatment diets in both periods of the 2 × 2 cross-over design used in the study. The two treatment diets contained on a dry matter (DM) basis: (1) SBS: 20% barley silage, 34.7% barley grain, 30% alfalfa cube, 13% crushed soybean seed and 0.36% sunflower oil, and (2) SFS: 17% barley silage, 34.6% barley grain, 40% sunflower seed incorporated into alfalfa cubes (cubes comprised 18% whole sunflower seed and 82% alfalfa hay), and 6.5% heat-treated soybean meal. The ingredients in the two diets were adjusted so that they would provide similar levels of energy (1.5 MCal kg-1) and have similar nutrient composition with regard to protein (16.7%), ether extract (5.2%) and fibre components (41%). Milk samples were collected, on 2 d prior to initiation of treatment diets and on days 6, 7, 13, 1 4, 20 and 21 of each experimental period. Cholecystokinin and insulin concentrations in blood samples collected at the start and end of each experimental period indicated no significant differences. Dry matter and net energy intake of cows fed the SBS and SFS were 23.3 and 21.4 ± 0.9 kg d-1; 34.4 and 31.6 ± 1.4 Mcal d-1, respectively, and in vitro volatile fatty acid concentration after 24 h of incubation was 123.3 and 114.7 ± 1.3 mM, respectively, and lower (P < 0.05) for the SFS diet. Milk, milk fat, protein and lactose yields from cows fed the SBS and SFS diets were similar (32.9 and 32.0 ± 2.4; 1.10 and 0.97 ± 0.07; 1.05 and 1.00 ± 0.05; 1.46 and 1.39 ± 0.12, respectively), but the CLA cis-9, trans-11 concentrations in the milk from cows fed the SBS and SFS diets were 4.05 and 7.28 mg g-1 of lipid and resulted in 66% higher (P < 0.01) CLA yield (g d-1) in milk for cows fed the SFS diet. This study confirmed that feeding sunflower seeds as a component of a hay cube increased CLA yield in the milk of dairy cows without affecting yields of other milk components.

Genipa americana L. well known as genipap, is a tree that is widely distributed throughout the Brazilian territory. The communities appreciate the genipap fruits, since they are used as food; in addition to that, their fruits have numerous seeds that can be used in the production of vegetable oil. This being, in this work inclined to a bromatological study of the genipap fruits and chemical composition and bioassays from vegetable oil seeds. Obtaining the highest percentage of lipids in the seeds that was of 7.08%, the highest percentage of humidity obtained was 74.66% present in the pulp, the highest amount of carbohydrates was found in the seeds, with a percentage of 79.37%, the highest percentage of ash present was 3.99% found in the pulp, another parameter analyzed were the proteins mostly present in the seeds with a percentage of 4.45% and finally the energy value was calculated, being the majority in the seeds with 398.98 Kcal/100 g. The fatty acid profile showed the highest percentage for the Linoleic Acid with 61.5%. The greatest inhibition in the antimicrobial assays was for S. typhimurium with 42.12% inhibition. In the tests performed for the inhibition of the enzyme acetylcholinesterase was 14.95%.

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 effects of breed and diet containing different types of silages on meat quality parameters and fatty acid profile of m. longissimus lumborum (MLL) were evaluated in a total of 30 Czech Fleckvieh (CF), Charolais (CH) and Charolais &times; Czech Fleckvieh (CH &times; CF) bulls. The animals were fed two mixed diets: MS (based on maize silage) and LCS (based on legume-cereal mixture silage and lucerne silages) with different concentrations of dietary energy and fatty acids. The MLL from CH bulls had the lowest content of dry matter (P &lt; 0.01), less protein (P &lt; 0.01) and lighter meat (P &lt; 0.01) compared to the CF. The extensive LCS diet reduced dry matter (P &lt; 0.01) and intramuscular fat (P &lt; 0.01) and increased the content of hydroxyproline (P &lt; 0.05). The CH bulls exhibited higher PUFA n-3 (P &lt; 0.05) and lower MUFA (P &lt; 0.05) compared to the CF, with the CH &times; CF being intermediate. The LCS diet enhanced the proportions of PUFA (P &lt; 0.05) and PUFA n-3 (P &lt; 0.001) and reduced MUFA (P &lt; 0.001). In conclusion, both breed and diet affected the meat quality and fatty acid profile of the intramuscular fat of the bulls. The replacement of maize silage with the legume-cereal mixture and lucerne silages in the diet reduced the concentration of intramuscular fat and improved its fatty acid profile from the human nutrition perspective.

AbstractThis study quantified the fatty acid profile with emphasis on the stereo-specifically numbered (sn) 2 positional distribution in TAG and the composition of main phospholipids at different lactation stages. Colostrum milk (n 70), transitional milk (n 96) and mature milk (n 82) were obtained longitudinally from healthy lactating women in Shanghai. During lactation, total fatty acid content increased, with SFA dominating in fatty acid profile. A high ratio of n-6:n-3 PUFA was observed as 11:1 over lactation due to the abundance of linoleic acid in Chinese human milk. As the main SFA, palmitic acid showed absolute sn-2 selectivity, while oleic acid, linoleic acid and α-linolenic acid, the main unsaturated fatty acids, were primarily esterified at the sn-1 and sn-3 positions. Nervonic acid and C22 PUFA including DHA were more enriched in colostrum with an sn-2 positional preference. A total of three dominant phospholipids (phosphatidylethanolamine (PE), phosphatidylcholine (PC) and sphingomyelin (SM)) were analysed in the collected samples, and each showed a decline in amount over lactation. PC was the dominant compound followed by SM and PE. With prolonged breast-feeding time, percentage of PE in total phospholipids remained constant, but PC decreased, and SM increased. Results from this study indicated a lipid profile different from Western reports and may aid the development of future infant formula more suitable for Chinese babies.
