Effect of organic acids and probiotics on intestinal health of Apis mellifera

Apis mellifera is an important pollinator that has a prominent impact on crops’ ecological balance. Beekeeping provides us with more valuable products like honey, pollen, propolis, beeswax, and royal jelly. The ongoing era demands more scientific and environment-friendly strategies to improve the beekeeping sector internationally. Nowadays, the use of synbiotics (a combination of probiotics and prebiotics) has been declared as the need of the hour. However, little bit studies have been carried out in this regard. To improve the beekeeping sector in Pakistan, a study was designed to exploration of probiotic and organic acids on bee tissue ileum (small intestine). 108 Colony forming units (C.F.Us) of Bacillus clausii and Lactobacillus brevis were provided with and without mixing in 1.96% acetic acid, 2.91% acetic acid, and 2.99% lactic acid to caged worker bees under controlled laboratory conditions. The provision did not affect the intestine harmfully. The mean intestinal lumen diameters (μm2) were 133.33 ± 8.82, 63.33 ± 3.33, 186.67 ± 72.19, 250.00 ± 28.87, 166.67 ± 17.64, 193.33 ± 46.31, and 140.00 ± 61.10 in experiments (1, 2, 3, 5, and 6 respectively) compared to control’s 113.33 ± 38.44. Worker bees with better digestion conditions prove honeybee’s health and efficiency.
