AbstractA partially balanced changeover design experiment was undertaken to evaluate the effects of level of fish oil inclusion in the diet on milk fat concentration and composition when offered to 50 lactating dairy cows in early lactation, which were offered either 5 or 10 kg concentrates/cow/day. Concentrates were formulated to contain similar concentrations of crude protein (CP), effective rumen degradable protein (ERDP) digestible undegradable protein and starch and to provide 0 (T0), 150 (T150), 300 (T300) or 450 (T450) g fish oil/cow/day or 300 g (T300B) fish oil/cow/day from a commercial fish oil premix. All animals were offered 5 kg treatment concentrate in two equal feeds through the in-parlour feeder at each milking. Additionally, cows offered the higher level of concentrates received a further 5 kg of T0 concentrate in two equal feeds per day through out-of-parlour feeders. Increasing the level of fish oil increased milk yield (P<0.01) and decreased the concentrations of fat (P<0.001) and protein (P<0.001). Increasing the level of fish oil decreased the concentrations of C6:0, C8:0, C10:0, C16:0, C14:0 and C18:0 and increased the concentrations of C18:1t, C20:0, C20:1, C20:4w6, C18:2c, C23:0, C20:5w3 and C18:2t. Relative to T300, T300B significantly decreased the concentrations of C20:4w6, but did not alter any of the other fatty acids. The transfer from feed to milk of EPA and DHA averaged 0.61 and 0.19 respectively across the three levels of fish oil supplementation. For T300 the efficiency of transfer of EPA was higher while the efficiency of transfer of DHA was lower to that for T300B. It is concluded that increasing fish oil supplementation decreased milk fat concentration by up to 15 g/kg. Also feeding fish oil is an efficient method of increasing EPA in the human diet through transfer into milk.

Level Of Importance

BackgroundThe aim of the study was to discover the extent of use of essential fatty acids (EFAs) in veterinary practice, conditions used in, preparation of EFA supplement used and rationale for their use and to investigate the awareness of the oxidation of some commercial fish oil supplement preparations.MethodsA web-based questionnaire was distributed via email to a dermatology list server and posted to veterinary Facebook groups with questions relating to the use of EFAs, supplement choice, conditions used in, the level of importance of various factors regarding their use and awareness of their oxidation.ResultsThere were 309 responses from 32 countries. EFA supplements were used by 92.2 per cent of respondents. The most commonly used preparation of EFA supplementation was veterinary oral supplements (75.1 per cent), followed by veterinary diets (14.4 per cent), shop bought fish oil supplements (7.7 per cent), enhancing the diet with oily fish (2.5 per cent) and finally using a commercial pet food (0.3 per cent). Only 46.3 per cent of respondents who used them were aware of the oxidation of EFAs. Veterinary oral supplements were perceived to be the best preserved, followed by veterinary diets and lastly commercial fish oil supplements.ConclusionA large number of respondents advised the use of EFAs for veterinary dermatological conditions but less than 50 per cent were aware of the potential for EFAs to oxidise.

Commercial fish oils (soft gel) have been widely traded in Indonesia, especially in East Java.The aimof this research was to determine the quality and stability of fish oils (soft gel) in East Java examined bySchaal oven method and to determine the amount of fatty acids in the commercial fish oil. The stabilityof the commercial fish oil was determined based on peroxide value, anisidine value, and total oxidationafter the oils were stored at 40oC for 6 days. The experimental design used in this research was completelyRandomized Design (CRD) with a treatment time of storage (H-0, H-2, H-4 and H-6). The quality of thecommercial fish oils was in accordance with IFOS on the parameters of the FFA, peroxide value, anisidin,and the total oxidation.The stability test results showed the fish oil quality decreased over time and onlyanisidine value was still met the IFOS standards. Sample S4 was found containing the highest amount ofomega 3 ada EPA, while S3 contained the highest amount of DHA.

Abstract Context.—The consumption of fish high in omega-3 fatty acids is advocated by the American Heart Association to decrease the risk of coronary artery disease. However, fish contain environmental toxins such as mercury, polychlorinated biphenyls, and organochlorine pesticides, which may negate the beneficial cardiovascular effects of fish meals. Toxin levels vary depending on both the fish source and the specific toxin, and neither farm-raised nor wild fish are toxin free. Fish oil supplements also prevent the progression of coronary artery disease and reduce cardiovascular mortality. However, only sparse data exist on the level of toxins in fish oil. In a previous study we showed that the amount of mercury in 5 over-the-counter brands of fish oil was negligible. Objective.—To determine the concentrations of polychlorinated biphenyls and other organochlorines in 5 over-the-counter preparations of fish oil. Design.—The contents of 5 commercial fish oil brands were sent for organochlorine analysis. Results.—The levels of polychlorinated biphenyls and organochlorines were all below the detectable limit. Conclusions.—Fish oil supplements are more healthful than the consumption of fish high in organochlorines. Fish oils provide the benefits of omega-3 fatty acids without the risk of toxicity. In addition, fish oil supplements have been helpful in a variety of diseases, including bipolar disorder and depression.

Waste Products

Catfish is playing an important role in aquaculture production; it is one of the primary commodities of inlandfisheries industry. Catfish meat has a yield of 49% and resulted in 51% of waste products. Thus catfish waste product has potency as source of fish oil which riches of omega-3. The Purpose of this study was to evaluate the suitable extaction method to obtain the high quality of fish oil from catfish skin. Based on the oxidative quality analysis data obtained extraction temperature of 60°C gives the best quality of fish oil with parameters such as peroxide value, free fatty acid, p-anisidine value, acid value and total oxidation of 38 meq/kg, 0.45%, 107,5 meq/kg, 895 mg KOH/kg and 187.5, respectively. The best yield was 18.75% which was obtained at extraction temperature of 75 °C. It was concluded that best extraction at 60°C, for 30 minutes, with solvent and sample ratio 1:1.

Fish oil is a source of omega-3s, specifically EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid). These fatty acids play an important role for human health. Commercial fish oil production is increasing, but most of the products do not meet IFOS standards. This is a challenge for producers to produce standardized fish oil. The aim of this research was to identify and determining quality of softgel commercial fish oil in Central Java areas based on International Fish Oil Standards (IFOS). The method used was the treatment of differences in the area of origin of commercial fish oil purchases followed by testing the peroxide value, anisidine value, and total oxidation, fatty acid profile, and analysis of free fatty acids. The results showed that the percentage of free fatty acids, peroxide values, anisidine values, and total oxidation values that met IFOS standards were 37 % (3 of 8 samples), 17 % (1 of 8 samples), 83 % (7 of 8 samples) and 50 % (4 out of 8 samples). The best fish oil that fulfil all IFOS parameters has been the sample fish oil E from Tegal. Fish oil D from Tegal has the highest content of omega-3, EPA, and DHA, with values<br />of 83.65%, 56.57%, and 26.74% respectively.

Physico Chemical

The local Channa species used in this research were Channa striatus (haruan) and Channa micropeltes (toman). Both samples were extracted using soxhlet extraction to procure the fish oil and then examined on its physico-chemical properties. The C. micropeltes species shows the highest yield of extracted fish oil (%, w/w) with dry weight basis (9.51 ± 1.20%). The physico-chemical results of the fish oil from haruan and toman were as follows respectively; colour: yellowish dark red for both species, specific gravity: 0.93 ± 0.10, 0.91 ± 0.03; AV: 21.78 ± 2.30 mg KOH/g, 5.55 ± 1.64 mg KOH/g; FFA: 10.95 ± 1.16%, 2.79 ± 0.83% and PV: 18.00 ± 6.56. meq./kg, 14.67 ± 3.79 meq./kg. Both fish oils showed a relatively comparable fatty acid profile. The availability of seven major enriched fatty acid constituents in both fish oils namely dodecanoic acid, 9-hexadecenoic acid, hexadecanoic acid, linoleic acid, oleic acid, octadecanoic acid, docosahexaenoic acid andaninfinitesimal amount of arachidonic acid (the main precursor for wound healing process) may perhaps berequisite for therapeutic consumption.
