This research was conducted in the countryside of Tartous, to aim for the analysis of moisture, protein, TSS and pH of royal jelly (RJ) harvested after 24 to 48 hours of grafting, compared with that traditionally harvested after 72 hours of grafting. As well as to analysis of these compounds in (RJ) within cells to brood of workers, compared with the (RJ) product in cups. 50 samples were analyzed in wet weight and dry weight for (RJ), which was harvested in this research.

Research summary
يهدف هذا البحث إلى تحليل مكونات الغذاء الملكي من حيث الرطوبة، البروتين، المواد الصلبة الذائبة (TSS)، ورقم الحموضة (pH) خلال مراحل إنتاجه المختلفة في الكؤيسات البلاستيكية وحضنة العاملات المفتوحة ضمن طائفة نحل العسل. تم جمع 50 عينة من الغذاء الملكي وتحليلها بالوزن الرطب والجاف. أظهرت النتائج اختلافات معنوية بين تركيب الغذاء الملكي المقطوف بعد 24 ساعة مقارنة مع ذلك المقطوف بعد 48 و72 ساعة. ازدادت الرطوبة مع مرور الوقت بينما انخفضت نسبة البروتين والمواد الصلبة الذائبة. كما أظهرت النتائج أن الغذاء الملكي المقطوف من العيون السداسية لحضنة العاملات كان مشابهاً للغذاء الملكي المقطوف بعد 24 ساعة من التطعيم ولكنه اختلف معنوياً عن ذلك المقطوف بعد 48 و72 ساعة. تشير النتائج إلى أن الغذاء الملكي المقطوف بعد 24 ساعة يتمتع بجودة أعلى من حيث الرطوبة والمواد الصلبة الذائبة، رغم أن الكمية المنتجة تكون أقل وتتطلب جهداً أكبر من قبل المربي.
Critical review
دراسة نقدية: على الرغم من أن البحث يقدم تحليلاً شاملاً لمكونات الغذاء الملكي خلال مراحل إنتاجه المختلفة، إلا أنه يفتقر إلى تحليل أعمق لتأثير هذه المكونات على صحة الإنسان واستخداماتها الطبية. كما أن الدراسة تركز بشكل كبير على الفروقات الكيميائية دون التطرق بشكل كافٍ إلى العوامل البيئية التي قد تؤثر على جودة الغذاء الملكي. بالإضافة إلى ذلك، يمكن أن تكون النتائج أكثر دقة إذا تم تضمين عينات من مناطق جغرافية مختلفة ونحل من سلالات متنوعة.
Questions related to the research
  1. ما هي المكونات الرئيسية التي تم تحليلها في الغذاء الملكي في هذه الدراسة؟

    تم تحليل الرطوبة، البروتين، المواد الصلبة الذائبة (TSS)، ورقم الحموضة (pH).

  2. كيف تؤثر فترة القطف على تركيبة الغذاء الملكي؟

    تزداد الرطوبة مع مرور الوقت بينما تنخفض نسبة البروتين والمواد الصلبة الذائبة. كما يزداد رقم الحموضة (pH) خلال فترات القطف.

  3. ما هو الفرق بين الغذاء الملكي المقطوف من الكؤيسات والغذاء الملكي المقطوف من العيون السداسية لحضنة العاملات؟

    الغذاء الملكي المقطوف من العيون السداسية لحضنة العاملات كان مشابهاً للغذاء الملكي المقطوف بعد 24 ساعة من التطعيم ولكنه اختلف معنوياً عن ذلك المقطوف بعد 48 و72 ساعة.

  4. ما هي الفائدة المحتملة من قطف الغذاء الملكي بعد 24 ساعة مقارنة بقطفه بعد 72 ساعة؟

    الغذاء الملكي المقطوف بعد 24 ساعة يتمتع بجودة أعلى من حيث الرطوبة والمواد الصلبة الذائبة، رغم أن الكمية المنتجة تكون أقل وتتطلب جهداً أكبر من قبل المربي.

This study was done in special apiary (Latakia province) to define the effect of adding some vitamins on the nutrition of the local honeybee colonies at the rate of acceptation in the plastic and wax cups are grafted with larva; and in the producti vity of royal jelly. The results showed that best of acceptation rate was achieved by vitamin C treatment that arrived to 85.41% in the wax cups and 75.83% in the plastic cups. According to results of the statistical analysis, it significantly surpassed upon all other treatments, whereas there wasn’t any significant difference between the treatment with vitamin Aand control, no matter what kind of cups it used. The results of average weight of the royal jelly in the cup showed that the treatment of vitamin C achieved the best value that reached to 0.348 g of the wax cups and 0.312 g of plastic cups.The statistical analysis showed superiority of the treatment vitamin C and B upon other treatments (vitamin A and control) while using the wax cups, whereas there was no significant difference in the average weight of the royal jelly between the two kinds of cups when treating with vitamin A and control.
This study was done in special apiary ( Lattakia province ) to define the effect of adding some vitamins (A,B,C) on the nutrition of the local honeybee colonies at the rate of acceptation in the plastic and wax cups are grafted with larva; and in the productivity of royal jelly , this study was carried out during two period : nectar flow season and nectar poor season.
This research was conducted in some apiaries that Royal Jelly produce at Lattakia Governorate, which is one of the most important areas of beekeeping in Syria. This research aimed to study the investment requirements, and calculate the annual produ ction costs, farm income indicators, and other economic indicators. In this research was used the descriptive economic analysis, data were collected of 8 apiaries, according to a form designed for this purpose, data were analyzed using appropriate statistical programs. Results showed the annual mean of royal jelly production costs, Returns, and profits in natural and additive feeding at Lattakia Governorate were 46865.5 Syrian pounds\hive, 112700 Syrian pounds\hive, 65834, Syrian pounds\hive, respectively, While net production costs, and net profits amounted to 42624.2 Syrian pounds\hive, and 8.57895 Syrian pounds\hive, respectively, and net relative income 140.50 %, also rent coefficient in relation to production costs and capital were 169.86 %, 115.16 %, respectively, and profitability coefficient in relation to production costs and capital were 140.48 %, 95.24 %, respectively, while economic efficiency, and the Payback period were 2.40, 1.05 year, respectively.
This study has been conducted on Syrian coastal area in 2013 season, aimed to analyze the cost of honey production and Farm income `at the Apiaries level, in addition to measure its net returns and economic efficiency. A field questioner was applie d to obtain elementary data of a random sample consisted of (304) of Apiary units. The results show that beekeeping is one of the economically viable agricultural projects, where most of the apiaries in the sample were able to achieve a positive net return as much, on average, about (405 834) SP / promiscuous, while its value was estimated at the hive level by about (7120) SP. It was found that the majority of apiaries in the study sample (87.8%) were able to achieve positive earnings, While the ratio (12.2%) exposed of the loss, and realized negative revenues . The results of the investment evaluation and financial analysis showed to the economic efficiency of the apiaries , reaching gross margin of the hive (11237.5) SP/year, and ratio of costs to revenue (62.9%), the profit ratio to total costs (59%), and general economic efficiency (1.59 ), and the Payback period (1.69) years.
The purpose of this research is to deduce the basis for calculating the cost of honey bee products since the actual costing of various levels on accurate basis is the right starting point for achieving all the goals of the cost systems. Because the actual cost is the basis of planning, control and reduction of that cost. Lack of information to properly determine product cost may cause choosing unhealthy competitive strategies, and make bad decisions, whether it related to product pricing or product selection. The research objective was reached through an analytical study of previous studies that discussed the economic feasibility of honey bee production projects in a variety of environments. In addition, a field study was carried out on the working beekeeping firms in Lattakia governorate during the period between the month of 11/2017 and the end of the month 8/2018. A number of conclusions were reached on the determinants of the cost of honey bee products, including the need to rely on the variable cost approach in preparing the list of honey product costs, the adoption of the production season as a period for the preparation of this list and a number of conclusions regarding the basis for calculating the depreciation of the assets of the honeybees and classified it as fixed cost which must included in the income statement for the financial cycle which ends at the end of the production seasons on 31/10 of each year.
