Abstract

This article is about the issue of increasing the egg production of Dekalb White hens through induced molting. For this study, hens at 60 weeks of age were divided into two groups (control and test groups), 53,760 animals in each one. The study continued until birds reached 94 weeks of age. During this study, induced molting for test group was performed in two stages. The first stage included seven days of fasting, watering ad libitum, dimmable lighting in the house for 3 hours. The second stage included the gradual giving of mixed feed starting with a daily intake of 40 g/bird, with an increase of 20 g weekly up to 115 g/bird; lighting period was increased weekly by 3 hours until the established standards were reached. After the end of fasting period, a probiotic preparation based on Bacillus subtilis culture in the amount of 0.2This article is about the issue of increasing the egg production of Dekalb White hens through induced molting.
