“…The increase in selenium concentration in breast meat due to dietary selenium supplementation is in agreement with findings presented by Ševčíková et al (2006), Dlouhá et al (2008) and Skřivan et al (2008a). Little information about the effect of SCH and SP on selenium content in breast meat and GSH-Px activity was published.…”

“…Accordingly, Dlouhá et al (2008) or Skřivan et al (2008a) confirmed that organic sources of selenium increased its content in breast meat. The organic form of selenium is deposited to a greater extent than the inorganic form.…”

“…Skřivan et al (2008a) found out the positive effect of organic and inorganic selenium form on an increase in body weight and Ševčíková et al (2006) or Dlouhá et al (2008) also reported the positive effect of organic selenium source. But other authors (Choct et al, 2004;Yoon et al, 2007) did not observe any significant differences in the final body weight of chickens after addition of selenium in organic form.…”

“…Dlouhá et al (2008) also recorded higher body weight after selenium supplementation in organic form. Conversely, Niu et al (2009) found an insignificant effect of selenium on body weight, while feed conversion was improved at a concentration of selenium supplement 0.2 mg/kg.…”

The study examined the effect of dietary supplements of sodium selenite (SS), selenium-enriched yeast (Sel-Plex®, 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® (SP) and selenium-enriched alga Chlorella (SCH). Selenium addition influenced body weight at 21 (P ≤ 0.001) and 35 (P ≤ 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 ≤ 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 ≤ 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 ≤ 0.001) influenced the GSH-Px activity in breast and thigh meat.

BackgroundSelenium is an essential mineral for poultry. The conflicting reports about its in ovo injection are the justification for the more detailed investigation.ObjectivesThe aim of this study was to investigate the effects of in ovo injection of organic selenium on the hatching traits of broiler chickens and their performance.MethodsThree hundred and twenty eggs of Ross 308 strain with an average weight of 65 g and 160 chicks were randomly divided into 4 treatment groups (each with 8 replicates of 10 eggs each for hatching parameters and 4 replicates of 10 chicks for broiler farming parameters): negative control (no injection), positive control (in ovo injection of 0.272 mL of normal saline solution) and 2 selenium treatments (in ovo injection of 2.72 or 5.44 μg of organic selenium). Injection was into the amniotic sac on the 10th day of incubation. Effects of in ovo injection on hatching and performance traits, blood parameters, immune responses, carcass characteristics, meat fatty acid profile, cecal microbial population and selenium consternation in the tibia were measured.ResultsFewer chicks from the injected treatments hatched than from the negative control group (p < 0.01). However, the injection of selenium increased feed intake and the final weight of the birds (p < 0.01). Blood parameters were also affected. Glucose and cholesterol in experimental treatment chicks was lower than those of the controls (p < 0.01), whereas blood lipoproteins (VLDL, LDL and HDL) and the ratio of cholesterol to HDL was significantly increased in the treatments injected with selenium (p < 0.01). There was no significant difference in the immune response or microbial population between the experimental groups, but carcass components, such as thigh, breast, wing and abdominal fat weight, were significantly greater in the selenium treatments.ConclusionsIntra‐egg injection of organic selenium produced favourable effects on performance of broiler chickens, although it had no effect on immune response or microbial population. However, the negative effect on hatching of chickens needs to be prevented to result in an acceptable economic return for the producer.
