THE INFLUENCE OF BETA-AGONIST SALBUTAMOL SULFATE ON SOME CHARACTERISTICS OF EGGS

This study was focused on the effect of beta-agonist salbutamol sulpha te on some characteristics of eggs. Thirty Rhode Island Red laying hen s were divided into three groups of 10 each. The repartitioning agent salbutamol sulphate in a pill form was added oral as following: the fi rst (A) group of hens six hour after oviposition (the influence on for ming egg shell) and the second (B) group of hens four hours after ovip osition (the influence on forming egg membranes). The third (K) group was representing the control group. The results of this trials demonst rated that eggs from groups obtained salbutamol sulphate six respectiv ely 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 compar ison with the control group. Eggs from B group of hens had firmer albu men (P < 0.001) and higher values for Haugh units than in the other tw o groups. Shell weight was not affected by beta-agonist salbutamol sul phate.
