This study was focused on the effect of beta-agonist salbutamol sulphate on some characteristics of eggs. Thirty Rhode Island Red laying hens were divided into three groups of 10 each. The repartitioning agent salbutamol sulphate in a pill form was added oral as following: the first (A) group of hens six hour after oviposition (the influence on forming egg shell) and the second (B) group of hens four hours after oviposition (the influence on forming egg membranes). The third (K) group was representing the control group. The results of this trials demonstrated that eggs from groups obtained salbutamol sulphate six respectively four hours after oviposition had thinner (P < 0.001) and darker (P < 0.001) shells and in A group also weighed less (P < 0.05) in comparison with the control group. Eggs from B group of hens had firmer albumen (P < 0.001) and higher values for Haugh units than in the other two groups. Shell weight was not affected by beta-agonist salbutamol sulphate.
