Lactobacillus types of cultures added to layer diets have shown some beneficial effects on layer performance at this research center (See A.S. Series 76-10, 77-20, 78-7, POULTRY 81-4 and 82-4).
The present experiment was conducted to study further effects of the addition of Lactobacillus types of cultures to layer diets. For this study, 432 Shaver-288 pullets at 28 weeks of age were used. The birds were kept in multiple cages in groups of 12. Nine such groups were assigned to each treatment. Treatment 1 was a regular 16% protein corn-soy type of ration used as the control. Subsequent treatments were the same as 1 plus Lactobacillus acidophilus IX, Lactobacillus acidophilus 2X and Lactobacillus acidophilus IX with Lactobacillus plantarum IX. Egg production, feed consumption and other production parameters were recorded and analyzed for twelve 28-day periods.
