Abstract

ABSTRACT: Seasonal nutritional content of honeybee pollen loads collected from five apiaries across the Al-Ahsa oasis, Saudi Arabia, was determined over a period of one year. Botanical composition of the pollen loads was dominated by rapeseed (Brassica napus L.), summer squash (Cucurbita pepo Thunb), date palm (Phoenix dactylifera L.), sunflower (Helianthus annuus L.), and alfalfa (Medicago sativa L.). The highest amounts (g/colony) of pollen loads were collected during spring and winter, and the lowest during autumn, and there were seasonal variations in and among nutrient content. The highest values of fructose, crude protein, lipids, and ash content were recorded from pollen loads collected during spring and winter, and the highest values of glucose and moisture content were recorded from pollen loads collected in autumn; pollen loads collected during summer showed the highest values of total and available carbohydrate, and crude fiber content. The high content of fructose, crude protein, lipids, and ash in pollen loads collected during the spring and winter seasons indicate they represent a valuable food supplement.
蜜蜂花粉负荷营养成分的季节变化
摘要:在一年的时间里,对从沙特阿拉伯阿赫萨绿洲的五个养蜂场采集的蜜蜂花粉的季节性营养含量进行了测定。花粉负荷的植物组成以油菜籽(Brassica napus L.)、夏南瓜(Cucurbita pepo Thumb)、椰枣(Phoenix dactylifera L.)、向日葵(Helianthus annuus L.)和苜蓿(Medicago sativa L.)为主,营养成分的季节性变化。果糖、粗蛋白、脂质和灰分的最高值记录在春季和冬季采集的花粉量中,葡萄糖和水分的最高值则记录在秋季采集的花粉负荷中;夏季采集的花粉总碳水化合物、有效碳水化合物和粗纤维含量最高。在春季和冬季收集的花粉中,果糖、粗蛋白、脂质和灰分含量很高,这表明它们是一种有价值的食物补充剂。
