“…Ding et al. () assessed the requirements of red‐legged partridges ( Alectoris rufa ) for selenium by feeding graded levels of 0.2, 0.3, 0.4 and 0.5 mg Se from Alkosel ® /kg. Selenium supplementation above 0.2 mg/kg, and up to 0.4 mg/kg, improved laying rate and hatching rate.…”

The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the application for renewal of authorisation of organic form of selenium produced by Saccharomyces cerevisiae NCYC R397 (Alkosel®) for all animal species. The FEEDAP Panel has delivered two opinions (on 2007 and 2016) on the safety and efficacy of the additive. The additive is characterised as organic selenium mainly selenomethionine (63%); it was initially authorised in 2007 with a content of 2,000–2,400 mg Se/kg (97–99 % of organic selenium) and in 2017 the authorisation was further amended to introduce a selenium range of 2,000–3,500 mg Se/kg. Additionally, in 2013, the initial authorising Regulation was modified to introduce a maximum supplementation selenium from this additive in feed (0.2 mg Se from Alkosel®/kg feed). The evidence provided indicates that the additive currently in the market complies with the conditions of authorisation. No new evidence was found that would make the FEEDAP Panel reconsidering its previous conclusions in the safety for target species, consumers and environment. In particular, the Panel confirms that the use of Alkosel® in animal nutrition does not pose a risk to consumers provided that the maximum selenium supplementation of 0.2 mg/kg feed from Alkosel® is not exceeded, yet respecting the maximum total selenium in feed of 0.5 mg/kg. Data on the characterisation of the additive and studies on skin/eyes effects led the Panel reconsider the safety for the user, concluding that Alkosel® is (i) hazardous upon inhalation, (ii) non‐irritant to skin and considered irritant for the eyes and mucosae, and (iii) a dermal sensitiser and likely a respiratory sensitiser. A recommendation regarding the denomination of the additive under assessment was proposed by the Panel.

“…In addition to broiler chickens, some other works with Se and VE were carried out with geese (Jerysz & Lukaszewicz, ), partridges (Ding et al., ), laying hens (Zduńczyk et al., ) and quails (Chitra, Viswanathan, & Edwin, ; Łukaszewicz, Kowalczyk, Korzeniowska, & Jerysz, ; Mobaraki & Shahryar, ; Sahin & Kucuk, ; Sahin, Sahin, & Onderci, ) but in these cases with the japanese species where the main purpose was to evaluate the quality of eggs, being scarce in the literature works carried out with meat quails. According to Rostagno et al.…”

Two experiments were carried out to determine the levels of supplementation of inorganic selenium (Se) and vitamin E (VE) in diets of quails aged 0-14 and 14-35 days old. A completely randomized design was used in a factorial design (Se = 0.1125; 0.2250; 0.3375 and 0.4500 mg kg diet × VE = 10; 23; 36 and 49 IU kg diet ). In experiment 1, quail (n = 2,400) were aged 0-14 days and were divided into 16 treatments, with three replicates of 50 birds. In experiment 2, quail (n = 1,680) were aged 14-35 days and were divided into the same treatments, with three replicates of 35 birds. At age 0-14 days, the levels of VE did not affect performance (p > .05); however, the feed conversion (FC) was influenced by a quadratic effect (p = .0515), according to the level of Se, with a higher level estimated at 0.29 mg Se kg diet . At age 14-35 days, there was a linear effect with interaction (Se × VE), for FC (p = .0150) and weight gain (WG; p = .0266). FC (Se, p = .0048 and VE, p = .0019) and WG (Se, p = .0049 and VE, p = .0068) improved linearly with increasing levels of Se and VE. The feed intake (FI) decreased linearly (p = .0582) as a function of VE. The carcass yield showed a quadratic effect (p = .0056) on the levels of VE, with a higher yield estimation of 27.24 IU VE/kg of diet. It can be concluded that the optimum level of supplementation at age 0-14 days was 0.29 mg Se kg diet and 10 IU VE kg diet and at age 14-35 days, it was 0.4500 mg Se kg diet and 49 IU of VE kg diet .

A study was conducted to evaluate the effect of dietary selenium (Se) sources (organic and inorganic Se at 0.30 ppm and basal diet at 0 ppm level of supplemented Se) on hatching traits in four varieties of Aseel chicken, Lakha, Mushki, Peshawari, and Mianwali. In total, 84 adult molted hens (50 wk old), 21 from each variety, were randomly assigned to 12 treatment groups in a 3 (Se diets) × 4 (Aseel varieties) factorial arrangement under a randomized complete block design. Each treatment was replicated 7 times with individual hens in each. Settable egg, fertility, hatch of fertile eggs, hatchability, A-grade chick, and embryonic mortality parameters were evaluated. The results indicated that the birds fed an organic Se supplemented diet had greater (P < 0.05) settable eggs, fertility, hatch of fertile eggs, hatchability, and A-grade chicks and reduced embryonic mortality than those fed inorganic or no Se. Among varieties, Mushki had lower (P < 0.05) fertility, hatch of fertile eggs, hatchability, and A-grade chicks than rest of three varieties. Interaction of Se sources and varieties indicated that dietary organic Se supplementation improved (P < 0.05) hatch of fertile eggs in Peshawari and Mianwali, whereas hatchability only in Peshawari variety and reduced embryonic mortality in Mianwali. It was concluded that dietary supplementation of organic Se could be used to improve hatching traits as well as reduce embryonic mortality in native Aseel chicken.
