“…These results support findings of our previous studies with respect to a role for dietary FO (rich in n‐3LPUFA) in the reduction of the concentrations of these nutritionally unfavorable compounds in the thigh and breast muscles . In fact, dietary oils, especially those rich in n‐3PUFA are known to increase the n‐3PUFA and decrease n‐6 PUFA contents and, as a result, to diminish the n‐6PUFA/n‐3PUFA ratio in the farm animals tissues …”

The aim of this study is to determine the effects of the addition of different chemical forms of selenium (Se)-selenate (SeVI) or selenized yeast (SeY) to chickens' diet containing equal amounts of fish (FO) and sunflower oils and lycopene (Lyc) on fatty acids (FA) profile and peroxidation yield in thigh muscles of chickens. FA profile is analyzed by gas chromatography coupled with mass spectrometry while content of malondialdehyde is determined by ultra-fast liquid chromatography (UPLC) with photodiode detection. The diets containing SeY or SeVI increase the feed conversion efficiency of chickens compared with the control diet. SeY or SeVI added to the diet containing Lyc and FO stimulates concentrations of monounsaturated and polyunsaturated (PUFA) FA in muscles. Muscles of chickens fed a diet only with Lyc and FO have the highest indices of atherogenic (A-SFA) and thrombogenic (T-SFA) saturated FA and the highest ratios of A-SFA and T-SFA to all assayed FA.Dietary Se-compounds also decrease the PUFA peroxidation indices in muscles compared with the diet containing only FO and Lyc. Therefore Se-compounds may be added to diets including FO and Lyc to improve the growth parameters, nutritive value, and oxidative stability of chicken meat. Practical Applications: Poultry meat, which is characterized by high protein content of high biological value, high minerals and vitamins, and low collagen and fat content, is recommended as particularly desirable in a balanced diet to replace red and highly processed meat. Also, relatively good price makes this type of meat one of the most popular among consumers. The present study aims to check if inclusion of different chemical forms of selenium into chickens' diets improves nutritional value of broiler meat. Feeding chickens with seleno-supplements significantly enhances poultry production efficiency and nutritional value of broilers' meat, because it favorably modifies FA composition (enhanced monounsaturated and polyunsaturated FA and decrease atherogenic and thrombogenic saturated FA in muscles) and reduces lipid oxidation in chickens' meat. These results are important from the both producers' and consumers' point of view and correspond to contemporary nutritional recommendations.

“…Recently, there has been a significantly increased interest in the modification of the fatty acid composition of animal origin products such as milk and milk products. Enriching the end products by high content n-3 polyunsaturated fatty acids (PUFA) feed supplements (such as oils, seeds, or freshwater and marine algae) is one of the most popular ways for producers [1][2][3]. One of the most interesting fatty acids is docosahexaenoic acid (DHA), which is contained in fish oil and marine algae in large-scale amounts.…”

The aim of this study was to evaluate the effect of the Schizochytrium limacinum marine algae on the milk composition and fatty acid profile, somatic cell count, and prevalence of pathogen bacteria in the raw milk of multiparous Alpine goats. Twenty-eight dairy goats were randomly allocated to two groups: control group (C)—fed with 1500 g alfalfa hay and 600 g concentrate; experimental group (MA)—received the same forages and concentrate supplemented with 10 g/head/day marine algae. The goats were housed indoors, while the experiment lasted five weeks, and the milk samples were taken every week. Marine algae feeding had no negative effect on milk composition. The marine algae inclusion significantly decreased the milk somatic cell count and the presence of udder pathogens in the MA group. Mean somatic cell count and presence of udder pathogens were 5.73 log cells/mL and 31%, respectively, in the C group, while these values were 5.34 log cells/mL and 10%, respectively, in the MA group. The marine algae supplementation significantly increased DHA and rumenic acid concentration in the milk of the MA group (0.32 and 0.99 g/100 g of fatty acids, respectively) compared to the C group (0.04 and 0.65 g/100 g of fatty acids, respectively). It can be concluded that a diet supplemented with marine algae significantly improves the udder health of goats and the concentrations of health-promoting fatty acids in milk.

“…Earlier reports showed that grazing considerably increased the rumenic acid and n-3 fatty acids contents in goat milk (Pajor et al, 2009;Delgadillo Puga et al, 2015). However, the most popular way to improve composition of foodstuffs by n-3 PUFA is supplementing animal diets with different plant oils, seeds, fish oil, freshwater and marine algae (Moate et al, 2013;Tsiplakou et al, 2017;Białek et al, 2018a). Moreover, fish oil and marine algae supplements in diets of ruminants are ABSTRACT.…”
