“…Marcel et al (2014) also reported the identical findings. These results are in line with the previous findings in utilizing organic sources of Se (Sevcikova et al, 2006;Chekani-Azar et al, 2010;Pappas et al, 2012) Based on these results, it is concluded that the diet supplement from organic source of Se (Se-enriched yeast) can be used to improve live final body weight, slaughtering characteristics and to enrich the meat of indigenous Aseel chicken with Se.…”

A study to investigate the influence of selenium on final body weight and slaughter traits of Aseel was conducted. Threeweeks-old 120 cockerels from Lakha, Mushki, Peshaweri and Mianwali varieties of Aseel were randomly selected and distributed into four groups, 30 cockerels each, subdivided into 3 treatment groups A, B (experimental groups), and C (control group) with 10 cockerels in each treatment. Birds were assigned three experimental diets. The diet for the birds of group A incorporated 0.3 mg/kg Se-enriched yeast and group B included 0.3 mg/kg sodium selenite, while C was fed the diet without Se (control diet). Final body weight, dressed weight, dressing%, eviscerated weight, eviscerated%; chest, thigh and giblets weight; selenium content in chest and thigh in Se-yeast fed birds were significantly increased than those got sodium selenite or control diet. The study concluded that Se-enriched yeast is more effective in improving body weight and slaughtering characteristics of Aseel.

“…Earlier studies on dietary Se levels and PUFA in chickens [16,17] have reported increased muscle n-3 LC PUFA levels when increasing dietary Se levels. In the current study the high Se dietary groups only showed a marginal increase in the level of EPA, but failed to show any affect on the other LC PUFA.…”

Chicken meat nutritional value when feeding red palm oil, palm oil or rendered animal fat in combinations with linseed oil, rapeseed oil and two levels of selenium

Chicken meat nutritional value with regard to fatty acid composition and selenium content depends on the choice of dietary oil and selenium level used in the chickens’ feed. The objective of this study was to investigate the effect of replacing commonly used rendered animal fat as a dietary source of saturated fatty acids and soybean oil as a source of unsaturated fatty acids, with palm oil and red palm oil in combinations with rapeseed oil, linseed oil and two levels of selenium enriched yeast on chicken breast meat nutritional value. The study also wished to see whether red palm oil had a cholesterol lowering effect on chicken plasma.204 male, newly hatched broiler chickens were randomly divided into twelve dietary treatment groups, and individually fed one out of six dietary fat combinations combined with either low (0.1 mg Se /kg feed) or high (1 mg Se/kg feed) dietary selenium levels. Linseed oil, independent of accompanying dietary fat source, lead to increased levels of the n-3 EPA, DPA and DHA and reduced levels of the n-6 arachidonic acid (AA). The ratio between AA/EPA was reduced from 19/1 in the soybean oil dietary groups to 1.7/1 in the linseed oil dietary groups. Dietary red palm oil reduced total chicken plasma cholesterol levels. There were no differences between the dietary groups with regard to measured meat antioxidant capacity or sensory evaluation. Chicken meat selenium levels were clearly influenced by dietary selenium levels, but were not influenced by feed fatty acid composition. High dietary selenium level lead to marginally increased n-3 EPA and higher meat fat % in breast muscle but did not influence the other LC PUFA levels. Chicken breast meat nutritional value from the soybean oil and low selenium dietary groups may be regarded as less beneficial compared to the breast meat from the linseed oil and high selenium dietary groups. Replacing rendered animal fat with palm oil and red palm oil had no negative effects on chicken muscle nutritional value with regard to fatty acid composition. Red palm oil decreased total chicken plasma cholesterol, confirming the cholesterol reducing effect of this dietary oil.

Selenium has been known for two centuries and its biological activities have been studied for nearly a hundred years, however the problem of Se deficit has still been persisting both in humans and animals. The cause of Se deficit in animals may be low Se level in soil. This mainly applies to cattle and sheep with their direct link to soil via roughage. The risk of Se deficit in pigs and poultry is lower due to lower dependence on soil Se level in the region and Se fortification in feed mixes. The present research focuses on the effects of Se on meat and egg quality, antioxidant activity of Se, effects on fatty acid levels, activity of glutathione-peroxidase, or the effect of Se on the immune system. Ensuring natural Se supply in human nutrition by food of animal origin, mainly poultry meat and eggs (the "functional foods"), is another area to which extensive attention has recently been paid.
