Effect of probiotics on growth, development and economically useful traits honeybees
Established that the possible use of probiotics in feed honeybees. Using a concentrate of lactic acid bacteria strain Lactobacillus plantarum 8P-A3 per 4 ml per 1 liter of syrup improves life expectancy in the spring to 9.5%. Bees begin to die in kindergartens in the control group at 10 days, and in the experimental group - 12 days. The highest mortality was found in the experimental group during the period from 24 to 28 days. The consumption of bee pollen weight of lactic acid bacteria from feces rektum was lower in the experimental group 18.0% (P ˂ 0,001). The greatest weight in excrement rektum found in the group of bees that eat only bee pollen. This group of individuals rektum weight reached the mark 38 mg. The smallest amount of undigested residues found in the group that consumed the pollen from lactic acid bacteria - the average weight of excrement rektum was 28.2 mg. Consumption concentrate of lactic acid bacteria does not cause weight increase in milk cells from trydobovymy larvae. The weight of royal jelly in the control group was 4.9 mg. The maximum weight of milk cells in experimental groups reached 6 mg. It found an increase in the number of brood grown by 16.2% in simyah who consumed probiotic preparation.
