| dc.description.abstract | A study was conducted to investigate the effects of different supplements on honeybee colony performances, evaluate farm honeybee performance and analyze honey quality and pollen. A study involved 30 A. M. monticola colonies in an apiary for treatments and across agro- ecology for onfarm evaluation. For honey quality and pollen analysis, 30 samples were taken from those hives which on farm performance evaluation was measured. The treatment diets included: T1: 50% sugar syrup, 14% roasted barley powder (beso), and 36% roasted spiced pea powder (Shiro). T2: 50% powdered sugar, 14% white sorghum powder, and 36% bakery yeast. T3: 50% powdered sugar, 14% white sorghum powder, and 36% skimmed milk powder. T4: 50% sugar syrup with an infusion of stinging nettle and 1% kerefa, along with 50% white sorghum powder. Feeds were provided at the entrance sides of the colonies. The study was conducted in two phases, the dry season (December 20, 2021, to March 22, 2022) and the rainy season (June 27, 2022, to September 7, 2022) which are dearth periods. While on-farm performance evaluation was done from September 10, 2021, to December 30, 2021, and March 27, 2022, to June 23, 2022 during active seasons of the year. Measurements of brood area, pollen, nectar, and honey space in the comb were taken using a transparent grid meter of frame size (cm2 ). Feed intake, profitability, honey stores, and total bee strength were also assessed. Honey yield, swarming tendency, foraging activity, defensive behavior, and absconding rate were measured during the active season. Honey quality and pollen were also analyzed. Notably, colonies that received T4 exhibited superior performance, with a feed intake of 98.3%, egg area of 464.9 cm2 , larvae area of 553.9 cm2 , pupae area of 627.1 cm2 , colony strength of 6.4 frames, and queen cell construction of 0.2, surpassing the other colonies. In addition, they had a nectar area of 54.3 cm2 , a pollen area was 68.7 cm2 , a honey area was 311.2 cm2 honey yield of 7 kilograms. Colonies found in the highland showed the highest value on all performance measurement parameters and recorded a honey yield of 22.13 kilo grams. While, colonies found in the lowland were active foragers, starting their activities at 5:13 a.m. and returning to the hive at 7:04 p.m., and aggressive than others. Their response time after disturbances was approximately 53.29 seconds, and they followed up to 182.42 meters. The average values for free acidity, moisture content, ash content, pH, and hydroxyl-methyl-furfural (HMF) were measured as 19.14 meq/kg, 17.43%, 0.09%, 3.13, and 5.49 mg/kg, respectively. During pollen analysis, 41 and 23 plants were identified during the first and second honey harvesting seasons. There were unique plants for each agro ecology. During both harvesting seasons, Eucalyptus globulus accounted for the highest percentage. In general, the diets presented by T4 performed better. A.m monticola in the highland showed better performance. The overall stated characteristics of the honey fell within the established ranges for honey quality standards of both the national and international and Eucalyptus globulus was the dominant plant which identified in the honey sample. But, further findings will be better regarding all these works | |
