    Effect of age upon utilization of selenium in chickens.

  • Original language description

    Utilization of selenium was examined in slow-growing laying-type chickens (SG) and in fast-growing broiler hybrids (FG) fed ad libitum on a diet with 265 microgramm of selenium/kg, including 128 microgramm of selenium added as sodium selenite. To 40 d ofage, coefficients of selenium retention increased (P < 0.05) daily in the SG and FG groups by 0.76 and 0.61%, respectively. From 40 to 100 d, the regression coefficients were not significant. Coefficients of selenium retention and retention per unit ofbody gain were higher in SG chickens. The influence of age on selenium content in BW gain of birds was evident (P < 0.01). From 5 to 40 d, allometric coefficients were 1.444 and 1.070 for SG and FG, respectively, and from d 40 to 100 the corresponding values were 1.282 and 1.081, respectively.

    Vliv věku na využití selenu u kuřat

  • Czech description

    Využití selenu bylo zjišťováno u pomalu rostoucích kuřat nosného typu (SG) a u rychle rostoucích brojlerových hybridů (FG) krmených ad libitum krmnou směsí s obsahem 265 mikrogramů selenu/kg, včetně 128 mikrogramů selenu přidaného ve formě seleničitanu sodného. Do 40 dní věku koeficient retence selenu stoupal (P < 0.05) denně u SG o 0.76 a u FG o 0.61%. Od 40 do 100 dní věku, regresní koeficienty nebyly průkazné. Koeficienty retence selenu a retence na jednotku přírůstku byly vyšší u SG. Vliv věku na obsah selenu v přírůstku byl patrný (P < 0.01). Od 5 do 40 dní byly alometrické koeficienty 1.444 u SG a 1.070 u FG, a od 40 dní do 100 dní byly 1.282 u SG a 1.081 FG.
