Effects Of Age In Days Of Honey Bees (Apis Mellifera L.) On Mineral Digestibility Rate Of Pollen

Minerals play an important role in the development, reproduction and production of bee,bees are essential nutrients. Age and dietary factors closely related to bees physiological state.In nature, different types of pollen have the different nutritional composition. In this study,Apis mellifera for the study, to the rectum of different ages Apis mellifera rape powder andtea pollen minerals copper, iron, manganese, zinc, sodium, potassium, calcium, magnesiumeight mineral digestibility, and two pollen diet bees food intake, midgut tissue morphology,antioxidant, digestive enzymes and indicators, and to explore the impact of age and dietaryfactors on the bee mineral digestibility, research content, such as the following:For new room Italian bee randomly divided into divided into three treatment groups, fourreplicates of each treatment group, each repeated60bees from the the sister queen beecolonies. One of the treatment groups for the control group fed with deionized water andsugar (excluding minerals), the other two treatment groups were fed rape powder and teapollen. Chyme in the intestinal emptying time (midgut) on an experimental basis in the beesfed different diets digestibility test research. The results show that:(1) two groups of beesminerals in feed intake increased with age,3,6and9-day-old bees mineral feed intake was nosignificant difference (P>0.05).(2) in the3-day-old and6-day-old, tea pollen diet group beescopper and manganese digestibility of canola meal diet group compared differences weresignificant (p <0.05), no significant9-day-old difference (P>0.05). Day3, day6and9daysof age, the tea pollen diets bees iron, sodium and calcium digestibility and rapeseed meal dietgroup differences were significant (P<0.05). Day3, day6and9days of age, the digestibilityof the tea pollen diets honey potassium and canola meal diet group showed no significantdifference (P>0.05). In the3-day-old and9-day-old, of tea pollen diets bees zinc digestibilityof canola meal diet group showed a significant difference (P<0.05),6days of age, no significant difference (P>0.05).3-day-old, the tea pollen diets bee minerals magnesiumdigestibility and rape meal diet group had no significant difference (P>0.05), day6and9days of age were significantly different (P<0.05).(3) Section3,6,9days old, tea pollen, rapepowder and the bees of the control diet group head and chest protein concentration,antioxidant capacity, midgut protease activity differences are significant (P<0.05).(4) Ageand dietary factors bee midgut the peritrophic membrane morphology.This study shows that different ages Apis mellifera can affect the mineral digestibilitypollen, bee mineral digestibility of different types of pollen are also different. Days of agefactor and pollen types of hormone affect the the bee body’s antioxidant capacity, midgutprotease activity and midgut organizational structure.
