This study examined the effects of supplementation of dietary sodium selenite and sodium enriched alga <I>Chlorella</I> on growth performance, selenium concentration in breast meat and excreta, activity of glutathione peroxidase in meat, and oxidative stability of meat in broilers. Sexed broiler cockerels Ross 308 were allotted to 3 dietary treatments, each comprising 100 chickens. The basal diet was supplemented with 0 (control) or 0.3 mg/kg Se from sodium selenite (SS) or Se-<I>Chlorella</I> (SCH). Dietary supplementation with SCH increased (<I>P</I> < 0.05) body weight. The breast muscle Se concentration was increased (<I>P</I> < 0.05) by SCH (0.70 mg/kg DM; 0.36 mg/kg DM in control) supplementation, but not (<I>P</I> > 0.05) by SS (0.49 mg/kg DM) supplementation. The concentration of Se in excreta was highest in the SS group. The activity of GSH-Px in breast meat was significant <I>P</I> < 0.05) in all treatments (0.16 U/g in control, 0.30 U/g in SS and 0.23 U/g in SCH group). The inclusion of SCH in the diet enhanced the oxidative stability of meat expressed as reduced malondialdehyde (MDA) values in breast meat after 0; 3 and 5 days storage in refrigerator at 3 to 5°C.

An experiment was conducted to compare the effect of dietary sodium selenite and selenomethionine on selenium and α-tocopherol concentration in breast meat, oxidative stability of meat in broilers, and on growth performance, but only as an unimportant criterion in this case. Sexed broiler cockerels Ross 308 were allocated to 3 dietary treatments, each comprising 100 chickens. The basal diet was supplemented with 0 (control) or 0.3 mg/kg Se from sodium selenite (SS) or selenomethionine (SM). Dietary supplementation with SM increased (<I>P</I> < 0.05) body weight, but only by about 3%. Breast muscle Se concentration was increased (<I>P</I> < 0.05) by both Se sources, but more by SM (1.32 mg/kg dry matter; 0.47 mg/kg DM in control). The concentration of Se in excreta was 3 times higher with SS supplement than with SM supplement. Dietary Se supplementation increased (<I>P</I> < 0.05) the α-tocopherol content of breast meat from 25.9 mg/kg DM in the control to 33.2 mg/kg DM when SM supplementation was used. Furthermore, lipid peroxidation decreased compared to the control. The inclusion of SM in the diet reduced (<I>P</I> < 0.05) malondialdehyde (MDA) values in breast samples after 0, 3, and 5 days of cooler storage, whereas SS decreased (<I>P</I> < 0.05) the MDA of breast meat after 0 and 3 days of storage. The results of this experiment indicate that selenomethionine in the diet of broilers is capable of simultaneously increasing the content of selenium and vitamin E in broiler meat plus its stability in storage.

Context Selenium (Se) is an essential trace element and plays pivotal roles in poultry nutrition. Aims The present study was designed to compare the impact of dietary supplementation of different sources of Se on growth performance, Se concentration of breast meat, and immune response of broiler chickens. Methods In total, 300 1-day-old as hatched broilers were randomly allocated to six dietary treatments, with five replicates of 10 birds per each. The experimental diets were as follows: (1) corn–soybean meal-based diet supplemented with 0.30 mg/kg of sodium selenite, (2) basal diet supplemented with 0.30 mg/kg of Se-enriched yeast, and (3–6) basal diet supplemented with 0.15, 0.30, 0.90 and 1.50 mg/kg of nano-Se respectively. Humoral immunity was assessed by antibody titer against a 5% sheep red blood-cell suspension and cellular immunity was measured by administration of phytohaemagglutinin-p at 38 days. Key results Results indicated that during the periods from 1 to 10 days, from 11 to 24 days, from 25 to 42 days and from 1 to 42 days, average daily gain, average daily feed intake, and feed conversion ratio did not differ among the treatments (P &gt; 0.05). Assessment of orthogonal contrasts at the whole phase of feeding showed that the average daily gain in the broilers fed organic Se was significantly (P &lt; 0.05) higher than that in those fed inorganic Se, as well as nano-Se in comparison to organic Se; such effects were not observed in earlier feeding stages. Se supplementation significantly increased the Se concentration of breast muscle (P &lt; 0.0001). The birds that received 1.50 mg/kg of diet nano-Se showed higher (P &lt; 0.05) total immunoglobulin and IgG titers in primary and secondary immune responses against sheep erythrocytes respectively. Toe web swelling after 24 h and 48 h of receiving phytohaemagglutinin-p was not affected by Se supplementation (P &gt; 0.05). Conclusions In conclusion, the addition of nano-Se gave better results than did inorganic (sodium selenite) and organic (yeast selenium) forms of Se in performance traits, breast meat Se concentration and antibody response of broilers. Implications Novel elemental nanometer particulates, including nano-Se, exhibit new characteristics and a different mode of actions in comparison with organic and inorganic forms of Se sources in poultry diets. Inclusion of the nano form of Se in broiler diets and study of productive performance, immunity responses and meat quality leads to improve balanced broiler diets formulation in view of Se.

Three experiments (EXP) were conducted using two hundred seventy male chicks Ross 308 in each (90 cockerels per treatment; 3 replications, 30 chickens per pen) for 42, 38 and 35 days. The basal diets (treatment 1) for three EXPs contained the identical ingredients, and the concentration of selenium (Se), methionine (Met) and total sulphur amino acids (TSAA) in the control diet was 0.11 mg/kg, 5.65 g per kg and 9.25 g/kg, respectively. Chicks in dietary treatment 2 were fed a basal diet supplemented with 0.3&nbsp;mg/kg of Se (EXP 1, 2 and 3) and in dietary treatment 3 they were fed a basal diet with the addition of 0.3 mg/kg of Se and 1 g/kg (EXP 1 and 2) or 2.5 g/kg of dl-methionine (EXP 3). In EXP 1, sodium selenite and in EXP 2 and 3 Se-enriched yeast were used as sources of supplemental selenium, respectively. The results indicated that the addition of Se or Se and Met into the diet of broilers did not significantly affect the final live weight of chickens and the feed consumption. Moreover, the concentration of Met (P = 0.004), Cys (P&nbsp;= 0.01) and tyrosine (P &lt; 0.001) in breast muscle increased with an increase in dietary Met content, and the isoleucine concentration decreased (P &lt; 0.001). Moreover, the addition of inorganic and organic sources of Se increased the Se content of breast meat (P &lt; 0.001). On the other hand, the addition of Met decreased the concentration of Se (P &lt; 0.001) in breast meat and reduced glutathione peroxidase activity and oxidative stability of raw breast muscle (P = 0.019, P&nbsp;&lt;&nbsp;0.001) and breast meat stored for 3 days (P = 0.016, P&nbsp;=&nbsp;0.006) in EXP 2 and 3.

AbstractSupplementation with selenium is common for dairy cows, but the importance of selenium source is not clear. This study aimed to compare nano-selenium (Nano-Se) and sodium selenite supplements for dairy cows on lactation performance, milk Se levels and selenoprotein (Sel) gene expression. Twelve multiparous Holstein cows were randomly divided into two groups: a control group fed a basal diet plus 0.30 mg Se/kg of DM as sodium selenite or Nano-Se for 30 days. Dry matter intake, milk yield and composition were not affected by dietary Se source (P > 0.05); however, the milk total Se levels and milk glutathione peroxidase (GSH-Px) activities were higher with Nano-Se supplementation than sodium selenite (P < 0.05). At the end of the experiment, Nano-Se supplementation significantly increased plasma Se levels and GSH-Px activity, compared with the sodium selenite supplement. The mRNA expression levels of glutathione peroxidase 1, 2 and 4; thioredoxin reductase 2 and 3; and selenoproteins W, T, K and F were markedly upregulated (P < 0.05) in the mammary gland of the Nano-Se group. Thus, the source of selenium plays an important role in the antioxidant status and in particular the Sel gene expression in the mammary glands of dairy cows, both being stimulated by nano sources.

The study examined the effect of dietary supplements of sodium selenite (SS), selenium-enriched yeast (Sel-Plex&reg;, SP) and selenium-enriched alga Chlorella (SCH) on growth traits, carcass analysis, selenium content in breast meat, glutathione peroxidase (GSH-Px) activity in breast and thigh meat and liver of chickens. The experiment was realized with seven hundred thirty-five cockerels Ross 308 randomly divided into 7 dietary treatments with 3 replications in each treatment. Chickens were fed a diet supplemented with 0 (control), 0.15 or 0.30 mg of selenium/kg in the form of sodium selenite (SS), Sel-Plex&reg; (SP) and selenium-enriched alga Chlorella (SCH). Selenium addition influenced body weight at 21 (P &le; 0.001) and 35 (P &le; 0.05) days of age. Significantly higher body weight at 35 days of age was determined in chickens receiving 0.15 mg of selenium from SP (2 122 g) and 0.3 mg of selenium from SCH (2 116 g) contrary to dietary treatment with a lower level of selenium from SCH (2 010 g) per kg of feed. The selenium content in breast muscle was increased (P &le; 0.001) by both the lower and higher selenium concentration in the form of SP (0.6 and 0.85 mg/kg dry matter) and SCH (0.6 and 0.82 mg/kg dry matter) in comparison with the control (0.31 mg/kg dry matter). A significant increase (P &le; 0.001) was ascertained even in SS treatments, but no significant differences were found between both levels. The selenium source and level, including SS, significantly (P &le; 0.001) influenced the GSH-Px activity in breast and thigh meat. &nbsp;

Intestinal Digestibility

AbstractThe aim of this study was to determine whether dietary supplementation with zinc oxide nanoparticales (NP-ZnO) as a substitute for the conventional ZnO affects the intestinal digestibility of selected minerals, growth performance and meat quality in turkeys. The replacement of ZnO with NP-ZnO had no effect on the intestinal digestibility of Zn, Cu, Fe and Ca, whereas the lowest dose of supplemental Zn reduced Zn digestibility. The applied inclusion levels and sources of Zn had no effect on the growth performance (except the feed intake) of turkeys, including liveability. No differences in the relative weights of the heart, spleen and bursa of Fabricius (except the liver), or the weights of the femur and tibia were found between the dietary treatments. Neither the dose nor the source of supplemental Zn influenced carcass dressing percentage or the share of breast, thigh and drumstick muscles in the carcass. In comparison with the highest and moderate doses of Zn, the lowest inclusion level of Zn contributed to increased yellowness of breast meat (P=0.005). The analyzed doses and sources of supplemental Zn exerted varied effects on the redox status of fresh and frozen breast meat. In conclusion, the growth performance of turkeys, carcass yield and composition as well as the redox status of fresh and frozen breast meat were generally similar, regardless of the dietary source and level of Zn. The beneficial effect of Zn addition at 100 mg/kg was improved Zn and Ca digestibility, and increased redness of breast meat.

The experiment aimed to investigate the effects of dietary β-mannanase supplementation on growth performance, apparent total tract digestibility (ATTD) of nutrients, intestinal integrity, and the immunological and oxidative stress parameters in weaning pigs. A total of 64 newly weaning pigs (initial body weight: 6.96 ± 0.70 kg) were allotted to two dietary treatments in eight replicates per treatment with four pigs per pen based on body weight and sex. Dietary treatments were 1.) CON (control: corn-soybean meal based basal diet) and 2.) β-mannanase (basal diet +0.06% β-mannanase). The β-mannanase supplementation did not affect growth performance, concentrations of acute phase protein, superoxide dismutase and glutathione peroxidase. However, the pigs fed the β-mannanase-supplemented diet had greater ATTD of ether extract, jejunum villus height, and villus height-to-crypt depth ratio, and lower crypt depth compared with those fed the CON diet (p < 0.05). The pigs fed the β-mannanase-supplemented diet tended to have the lower count of E. coli in cecum than those fed the CON diet (p = 0.08). In conclusion, dietary β-mannanase supplementation did not affect growth performance, immune response and oxidative stress of weaning pigs, whereas it increased fat digestibility and had positive effects on intestinal integrity and cecum microflora by reducing the count of E.coli.

The present study was conducted to evaluate the effects of replacing corn with brown rice on growth performance, nutrient digestibility, carcass characteristics, and gut microbiota of growing and finishing pigs. A total of 100 growing pigs (23.80 ± 2.96 kg BW; 10 weeks of age) were randomly allotted to 4 dietary treatments (5 pigs/pen; 5 replicates/treatment) in a randomized complete block design (block = BW) as follows: corn-soybean meal basal diet (CON) and replacing corn with 50% (GBR50), 75% (GBR75), and 100% (GBR100) of ground brown rice. Each trial phase was for 6 weeks. During the growing period, there were no differences on growth performance and nutrient digestibility among dietary treatments. Similarly, no differences were found on growth performance, nutrient digestibility, and carcass characteristics of pigs during the finishing period among dietary treatments. As a result of the beta diversity analysis, microbial populations were not clustered between CON and GBR100 during the growing phase, but clustered into two distinct groups of CON and GBR100 during the finishing phase. In conclusion, brown rice can be added to the diets of growing-finishing pigs by replacing corn up to 100% without negatively affecting growth performance of the pigs; additionally, this may have an effect on changes in pig intestinal microbiota if continued for a long time.
