“…Growth retardation in stressed groups of the present study is probably due to decreased muscle protein synthesis and elevated proteolysis in muscle (Hayashi et al, 1994). The muscle proteolysis could be the result of damage of muscle proteins caused by active oxygen (Hunt et al, 1988), and this may be reversed by some antioxidants such as epigallocatechin gallate (Eid et al, 2003). It is not known yet whether lycopene has such an effect.…”

The Effects of Tomato Powder Supplementation on Performance and Lipid Peroxidation in Quail

et al. 2008

Recent studies have suggested a protective role for lycopene, an antioxidant carotenoid, in the prevention of stress including environmental stress. Tomatoes and tomato products are the major dietary source of lycopene. The objective of the present study was to investigate the effect of dietary tomato powder supplementation on the performance and lipid peroxidation of meat in Japanese quail (Coturnix coturnix japonica) exposed to a high ambient temperature of 34°C. A total of 180 ten-day-old male quails were randomly allocated into 6 groups consisting of 10 replicates of 3 birds. Birds were kept in wire cages in a temperature-controlled room at either 22°C (thermoneutral) or 34°C (heat stress) for 8 h/ d (0900 to 1700 h during the study). Birds were fed either a basal diet or the basal diet supplemented with 2.5 or

“…One possible explanation for this might be the antioxidant activity of Se. High ambient temperature significantly depresses growth performance of broiler chickens (El-Deep et al, 2014), while supplementation with antioxidants such as probiotics, trace elements, and vitamins has proven beneficial in alleviating the adverse effects of high ambient temperature challenge (Eid et al, 2003(Eid et al, , 2008Lin et al, 2006;Sahin et al, 2009). It has been shown that dietary Se supplementation improves antioxidant status by activating GSH-Px (Yoon et al, 2007;Ebeid et al, 2013).…”

Effects of Dietary Nano-Selenium Supplementation on Growth Performance, Antioxidative Status, and Immunity in Broiler Chickens under Thermoneutral and High Ambient Temperature Conditions

The objective of the present study was to examine the effects of nano-selenium on growth performance, antioxidative status, and immune function in broiler chickens reared under thermoneutral (22±1℃) or high ambient temperature (35±1℃) conditions. Thirty-six broiler chicks at 15d old were randomly divided into 6 treatments in a 3 ×2 factorial design. The main factors included the dietary supplementation (basal diet without Se supplementation [control], basal diet with 0.3 mg of nano-elemental Se per kilogram of diet [nano-Se], and basal diet with 0.3 mg of sodium selenite per kilogram of diet [SSe]) and the ambient temperature challenge (22±1℃ or 35±1℃). The birds were given the experimental diets from 15 to 30 d of age. High ambient temperature significantly depressed body weight gain, feed intake, feed conversion ratio, breast muscle weight, and abdominal fat weight, while feeding nanoSe clearly alleviated these negative effects of high ambient temperature. In addition, feeding nano-Se increased glutathione peroxidase mRNA expression in liver and alleviated the negative effects of high ambient temperature via reducing the malondialdehyde content in liver and breast muscle. Furthermore, feeding nano-Se increased mRNA expression of cytokine genes (interleukins 2 and 6) under both thermoneutral and high ambient temperature conditions. Under both thermoneutral and high-temperature conditions, broiler chickens fed nano-Se had higher Se and vitamin E concentrations in breast muscle than broiler chickens fed the control diet. In contrast, feeding SSe at the same dose as nano-Se did not alleviate the negative effects of high ambient temperature on broiler chickens. In conclusion, dietary supplementation with nano-Se at 0.3 mg/kg diet might enhance growth performance by improving antioxidative or immune properties in broilers reared under high ambient temperature.

“…For instance, the results obtained for grape and olive pomace, olive leaves, grape seeds, marigold, cinnamon, sage, green tea, tannin, thyme, and rosemary extracts, as well as different mixtures of polyphenol sources, can either increase (Eid et al, 2003;Tavarez et al, 2011;Lu et al, 2014;Bravo et al, 2014), decrease, or have no effect on productivity (Goni et al, 2007;Gurbuz et al, 2010;Brenes et al, 2010;Rezar and Salobir, 2014).…”

Effects of Olive Leaf and Marigold Extracts on the Utilization of Nutrients and on Bone Mineralization using Two Different Oil Sources in Broilers

et al. 2018

The aim of this study was to investigate the effects of olive leaf and marigold extracts on the apparent total tract digestibility (ATTD) of the principal nutrients and energy, as well as on mineral utilization (Ca, P, Mg, Mn, Fe, Cu and Zn) in relation to bone characteristics in broilers fed walnut-or linseed oil-supplemented diets. Thirty-six 12-dayold commercial broilers Ross 308 were reared in metabolic cages, assigned to one of the six dietary treatments (3×2 factorial design): three supplements (not supplemented, olive leaf extract, or marigold extract), and two oils (walnut or linseed oil). The results showed that the marigold extract reduced Zn and P balances and tended to lower the balance of ash and Mg, and the ATTD of Zn and Mg. Diets with linseed oil increased the ATTD of acid detergent fiber and reduced the ATTD of the organic residue and Cu. No differences in the bone characteristics of tibia were observed between treatments. These results indicated that the inclusion of marigold extract had a negative effect on the Zn and P balance, and that neither extract had any major effect on the digestion and utilization of energy and other investigated nutrients, or on bone mineralization, irrespective of the oil source included in the diet.
