Fattening Pigs

The effect of supplementing fattening pigs with oils differing in MUFA (monounusaturated fatty acids) and PUFA (polyunsaturated fatty acids) level addition for fatteners diets on the cholesterol content of m. longissimus was investigated. In a feeding trial with 48 crossbred pigs [? ($ White Polish Large x S Polish Landrace) x <$ Pietrain] randomly assigned to four treatments groups of 12 animals each (6 gilts and 6 barrows), dietary supplements of 3% maize, sunflower or linseed oil in the experimental groups and of 3% lard in the control group were applied. Total cholesterol in the longissimus muscle of linseed oil supplemented pigs was found to decrease significantly (PO.01) compared to the lard-fed pigs (60.75 vs. 71.37 mg/100 g of fresh tissue). Similar tendencies for reduced cholesterol level in longissimus muscle of sunflower and maize oil supplemented pigs were also noted. The production of pork with reduced total cholesterol seems to be important in terms of consumer health and culinary value.

The experiment involved 24 Polish Landrace gilts, divided into 2 groups, and fed from 70 to 100 kg b.w. with a complete mixture containing 15% full fat flax with or without 0.35% probiotic (Acid Pack 4 Way). The experiment concluded with slaughtering, and dissection, meat of Longissimus dorsi muscle was sampled to determine fatty acids composition and total cholesterol content. The supplement was observed to have no effect on fattening, slaughter and physicochemical traits of meat. The probiotic supplement did not significantly affect the composition of fatty acids in Longissimus dorsi muscle. Total cholesterol level was observed to decrease from 61.3 to 55.5 mg/100 g fresh tissue. There were significant differences between HDL increases and LDL decreases in blood serum of the probiotic supplemented animals (P?0.01).

In order to study the effect of dietary supplement of linseed oil on polyunsaturated fatty acids (PUFAs) in egg yolk of Gallus domestiaus, total 160 healthy Gallus domestiaus of 26-week old were randomly selected and divided into 4 groups, each of which included 40 chickens fed outdoors with an area of 63 m2 and free food and drinking water. The control group (CK) was fed the basic diet, and the experimental group was added 1, 3 and 5% of linseed oil in the fundamentals of diet (experimental group 1, 2 and 3, abbreviated as P1, P2, P3), respectively. The content of PUFA and the value of n-6 PUFA and n-3 PUFA in egg yolk were determined by gas chromatography with 24 eggs randomly selected in each group after 10th, 25th and 40th days of the commence of the experiment. We found that the levels of α-linolenic acid (C18:3n3, ALA) and docosahexaenoic acid (C22:6n3, DHA) in egg yolk were clearly higher than the CK when 3% linseed oil or 5% linseed oil were added in the diet during the three experiment periods, in which the contents of linoleic Acid (18:2n6c, LA) and arachidonic acid (C20:4n6, ARA) in egg yolk differ little between P1, P2 and P3 and the CK while the value of n-6 PUFA and n-3 PUFA in egg yolk of the P2 and P3 groups decreased significantly. The comprehensive comparisons suggested that the content of C18:3n3 and C22:6n3 in egg yolk could be clearly increased in the P2 while the value of n-6 PUFA and n-3 PUFA decreased. This study provides theoretical basis for the production of functional eggs enriched with C22:6n3 and C18:3n3.

The aim of the study was to determine the effect of three different phyto-humic feed preparations on the basic qualitative characteristics of eggs, i.e. total cholesterol content and fatty acid profile of the yolk. The study was carried out on 80 Lohmann Brown (LB) laying hens in an experimental facility with a floor maintenance system on a straw bedding (5 layers/m2). A control group (K) and three experimental ones (A, B, C), with 20 birds in each (in separate pens), were created. The birds were placed in the 16th week of life, while the experimental preparations were introduced in the 22nd week of life and were administered for 43 weeks (constant 3% addition to the feed mixture).The following preparations were applied: humic-peat (H-t) in group A, humic-herbal (H-z) in group B, and humic-lucerne (H-1) in group C. The eggs for the study were collected three times, 30 eggs from each group in the following periods: 1st series – 31st week of life (peak of laying period); 2nd series – 54th week of life (later phase of laying period) and 3rd series – 65th week of life (final phase of laying period). Six samples (mean of 5 well-mixed yolks) from each group in three laying periods (360 eggs were used in total) were prepared for laboratory analyzes (lipids examination). Laboratory analyzes were performed using a chromatograph – Finnigan Focus PolarisQ manufactured by Thermo Electron with capillary columns: HP-88 by Agilent J&W (fatty acids) and Rtx-1MS by Restek (cholesterol). The applied phytohumic preparations – but only those with a share of dried lucerne or herbs – significantly (p ≤ 0.05) reduced total cholesterol content, especially in group C (10.88 mg/g yolk) compared to group K (11.94 mg/g yolk). All preparations positively influenced the fatty acids profile of yolk; there was a significant (p ≤ 0.05) increase in the concentration of n-3 PUFAs (max 2.84% in the group B), the n-6/n-3 ratio decreased significantly (most beneficial 8.33 in group B), and lipids quality improved: atherogenic index (AI) decreased significantly (p ≤ 0.05) in group A (0.32) and thrombogenic index (TI) was a significantly (p ≤ 0.05) lower in all experimental groups (0.83 – 0.84) compared to group K (0.36 and 0.87 respectively). Dietary phyto-humic preparations increased the nutritional and dietary value of hen eggs.

Abstract The aim of the study was to determine the effects of prebiotic GOS on muscle histomorphometry and the total lipid, total cholesterol content and fatty acids profile in the meat of common carp. The 60-day-long experiment was performed on one-year-old fish. Three diets were used in the experiment: control diet 1 (C) with no microbiota affecting feed additives, diet 2 (B1) with 1 % of GOS, and diet 3 (B2) with 2 % of GOS. At the end of the trial, 16 individuals from each treatment group were used for the analyses. Fish meat from the B1 group had significantly higher lipid content compared to B2, but neither B1 nor B2 groups were different from the control group. The percentages of SFA, MUFA, PUFA, indexes n-3/n-6, PUFA/SFA, AI and TI, and total cholesterol content were not affected, in contrast to C14:0, C16:1 n-7, C18:0, C18:2 n-6, C20:4 n-6, and total n-6 FA. GOS significantly increased the percentage of normal fibres, while the lower number of fibre atrophy and splitting were observed. The results confirm that diet supplemented with 2 % GOS may be recommended as feed additive in carp nutrition due to positive effects on some fatty acids profiles and muscle microstructure.

For the first time, we have studied the influence of polyunsaturated fatty acids on cholesterol metabolizing activity of bifidobacteria. High levels of destruction of cholesterol in the process of cultivation of strain Bifidobacterium Longum DK 100 was noted. Based on the results, the technology of probiotic dietary supplements (DS), enriched with polyunsaturated fatty acids, has been developed. The paper reveals that the introduction of probiotic DS leads to a twofold reduction in total cholesterol in the experimental groups in comparison with the control one, which indicates high effectiveness of DS. It has been observed that against the background of the atherogenic diet, the employment of probiotic DS is accompanied by a significant reduction in triglyceride levels by 37% and 45% in the "linen" and "cedar" groups, respectively, compared to the control group of animals. It has been established that in the blood serum of animals of experimental groups, the level of high-density lipoproteins increases by 45% in "linen" and 40% in "cedar" groups, while low-density lipoproteins decreased by 19% and 23% respectively. With the introduction of probiotic DS with linseed oil, the atherogenic index decreases by 83%, and with the cedar one by 86%. The results confirm the hypocholesterinemic effect of DS during cholesterol loading.

Many researchers have pointed out that the intake of omega-3 and -6 fatty acids is beneficial to animal health and reproductive capacity, but the effect of fatty acids on the histomorphology of ram testes is still unknown. The aim of this study was to investigate the effect of linseed oil containing polyunsaturated fatty acids on the morphology and histomorphometric characteristics of ram testis and epididymis. Testes of 12 Lithuanian local coarse wool rams were investigated histomorphologically and histomorphometrically in the present work. The rams were divided into two groups, an experimental group and a control group following, the principle of analogues – the same origin, age, weight, and condition score. The experimental group (n = 6) received 2% linseed oil sediments while the control group (n = 6) received 1.2% sunflower oil for 9 months. The diameter of testicular tubules and the height of the germinal epithelium, the spermatogenic index and the number of Leydig cells were higher in the experimental group than those in the control group. In addition, the number of degenerated tubules was not significantly lower in the group that received 2% linseed oil sediments. Still, the height of the epididymal epithelium was lower than that in the control group....

The aim of this study was to compare the effect of two different types of oils in diet on the fatty acid profile in the eggs of layers and to include a particular type of oil as a supplement of feeding mixtures for layers in order to support the development of functional foodstuffs. Thirty layers fed a diet containing soybean oil constituted the control group (soybean oil is the most frequently used oil added to feeding mixtures). In the experimental group (thirty layers), soybean oil was replaced with linseed oil at the same amount (3 kg of oil per 100 kg of feeding mixture). Feeding was provided ad libitum for all days of the month. After one month, egg yolks were analysed and the fatty acid profile was compared. Significant differences (P ≤ 0.05) were found in the concentration of myristic acid that belongs to the group of saturated fatty acids. Eggs in the experimental group showed higher concentrations of myristic acid compared to the control group (0.20 g/100 g of fat and 0.18 g/100 g of fat, respectively). Highly significant differences (P ≤ 0.01) were found for heptadecanoic acid but the trend was opposite to that of myristic acid; concentrations of heptadecanoic acid in the experimental group were lower than those in the control group. Highly significant differences (P ≤ 0.01) were found for n-9 monounsaturated fatty acids where egg yolks in eggs from layers fed linseed oil contained higher concentrations of oleic acid, myristoleic acid, and palmitoleic acid. Lower concentrations of n-6 fatty acids (P ≤ 0.01) were found after the addition of linseed oil in eggs. Linseed oil showed a positive effect on n-3 fatty acids (α-linolenic acid), its concentration in the control and experimental group was 0.82 g/100 g of fat and 5.63 g/100 g of fat, respectively. The possibility of influencing the fatty acid profile in eggs is very important for the development of functional foods.

Abstract The effect of modified proprietary poultry feed on cholesterol excretion in laying birds was evaluated. The study sort to lower the cholesterol content of eggs at the point of their physiological formation via a modification of the proprietary feed fed to laying poultry birds. This was with a view to lower the net cholesterol content in their eggs, thereby lowering the cholesterol levels available in such eggs for intake upon consumption. A 20% rice bran modification of the proprietary feed was made. Animal subjects were divided into experimental and control groups and the mean total cholesterol in their faecal droppings where determined before and after varying their feeding programs. Whereas the experimental group was fed with the modified feed, the control group was maintained on the unmodified feed. Enzymatic colorimetric method was used for the determination of mean total cholesterol in the dried faecal droppings of each group of birds under investigation. The results showed that the mean total cholesterol excretion before and after the modified feed regimen were 5.97±0.16 mg/g and 9.99±0.47 mg/g respectively and were found to be significantly different when compared using a t-test at p > 0.05 and 49 degree of freedom The results also showed that the modified proprietary poultry feed increased total cholesterol excretion in the faecal droppings of laying birds fed with the modified feed by 67.3%, and this was found to be statistically significant at p > 0.05. Hence, a 20% rice-bran modification of the proprietary feed yields a modified feed with a proven potency in elevating total cholesterol excretion while producing no drastic deviation from the proximate composition of the unmodified proprietary feed and is thus likely to have no adverse effect on the productivity of laying birds.

Fish Feeds

The projected stagnation in the catch from global fisheries and the continuing expansion of aquaculture is considered against the background that fishmeal and fish oil are major feed stocks for farmed salmon and trout, and also for marine fish. The dietary requirement of these farmed fish for high-quality protein, rich in essential amino acids, can be met by sources other than fishmeal. However, the highly-polyunsaturated fatty acids eicosapentaenoic acid (20:5n-3) and docosahexaenoic acid (22:6n-3) present in high concentrations in fish oil are essential dietary constituents for marine fish and highly-desirable dietary constituents for salmonids. Currently, there is no feasible alternative source to fish oil for these nutrients in fish feeds. Vegetable oils rich in linoleic acid (18:2n-6) can partially substitute for 20:5n-3 and 22:6n-3 in salmonid and marinefish feeds. However, this is nutritionally undesirable for human nutrition because the healthpromoting effects of fish-derived 20:5n-3 and 22:6n-3 reflect a very high intake of 18:2n-6 relative to linolenic acid (18:3n-3) in Western diets. If partial replacement of fish oils in fish feeds with vegetable oils becomes necessary in future, it is argued that 18:3n-3-rich oils, such as linseed oil, are the oils of choice because they are much more acceptable lrom a human nutritional perspective, especially given the innate ability of freshwater fish, including salmonids, to convert dietary 18:3n-3 to 20:5n-3 and 22:6n-3. In the meantime, a more judicious use of increasinglyexpensive fish oil in aquaculture is recommended. High priorities in the future development of aquaculture are considered to be genetic improvement of farmed fish stocks with enhanced abilities to convert C18 to C20 and C22n-3 polyunsaturated fatty acids, enhanced development of primary production of 20:5n-3 and 22:6n-3 by single-cell marine organisms, and continuing development of new species.
