The effects of different pollen substitute feed on feed intake,colony potential,and physiological indicators of worker bees in bee colonies
To study the effects of different pollen substitute feed on feed intake,colony potential,and physiological indicators of worker bees in bee colonies.Select 16 groups of Chinese honeybees with similar reproductive capacity and worker bees,and randomly divide them into 4 groups,with 4 groups in each group.Each group of bee colonies used tea pollen(T0 group),corn protein powder(T1 group),rapeseed cake(T2 group),and beer yeast(T3 group)as feed ingredients.The experiment started from the spring reproductive period and lasted for a total of 60 days.The results showed that:(1)The total feed intake of the four bee colonies was 1671.84 g,1972.84 g,1428.63 g,and 2298.47 g,respectively.Among them,compared with the T0 group,the total feed intake of the T1 and T3 groups significantly increased by 18.00%and 37.48%(P＜0.05).(2)On the 20th day of the experiment,the bee colony potential of the T3 group was significantly higher than that of the T0,T1,and T2 groups(P＜0.05);On the 40th day of the experiment,the bee colony potential of the T3 group was significantly higher than that of the T0 and T2 groups(P＜0.05);On the 60th day of the experiment,the bee colony potential of the T1 and T3 groups was significantly higher than that of the T0 and T2 groups(P＜0.05).(3)The initial weights of the four groups of worker bees in the bee colony were 0.11,0.12,0.09 and 0.11g,respectively.Among them,compared with the T2 group,the T0,T1,and T3 groups significantly increased the initial weight of worker bees by 22.22%,33.33%,and 22.22%(P＜0.05).The protein content in the head of adult worker bees in the T1 group was significantly higher than that in the T0 and T2 groups(P＜0.05).From this,it can be seen that using corn protein powder and beer yeast as feed materials can increase the feed intake of the bee colony,promote the growth of the bee colony potential,and improve the physiological indicators of worker bees;Using rapeseed cake as feed material reduced the initial weight of worker bees.
