Application of probiotic IMB 52 in laying hens nutrition

Abstract

The goal of this experiment was additional verification of the probiotic preparation Enterococcus lactiferm, the influence of this IMB 52 feed mixture on feed consumption, nutrient consumption, production and weight of eggs in laying hens. The trial included laying hens of the ISA - Brown type, which were divided into a control group (group K) and 3 experimental groups (A, B, C), each containing 108 hens. Laying hens were fed by the feed mixture HYD - 10 upto first 43 weeks. The feed mixtures were different in concentration according to Enterococcus faecium in the probiotic preparation IMB 52. Group A was fed with 2.5.1011, the second group B with 5.0.1011 and third group C with 1.1012 cfu.t-1. The probiotic preparation IMB 52 was produced by BIOMIN Company in Austria. The highest feed intake per hen per day was in the K group (124.07 g) as compared with experimental groups which consumed 97.90 %, 96,37 % and 97.27 % of feed, respectively. A similar tendency was found in the intake of dry matter, crude protein and energy, normalized for one egg, and the same for per kg egg mass produced. Lowest values were registered in group B. Egg weight was the highest, 63.65 g in group A, which was also statistically significant (P<0.05) in comparison with control group K. Groups B and C registered higher values of egg weight (63.45 and 63.03) compared with the control group. Laying intensity varied from 91.93 % to 92.83 % with the lowest value found in group A and the highest value in group C. These differences between groups (less than 1 %) were not statistically significant though (P>0.05). The production of egg mass was from 8.13 - 8.04 kg per head with the lowest value in group B and the highest in group C.
