هدف البحث إلى تحديد الحجوم الاقتصادية للإنتاج و السعات الإنتاجية المختلفة و التعرف إلى مدى اقتراب الحجوم الفعلية أو ابتعادها عن نظائراها الاقتصادية، و ذلك حسب المناطق المطرية في إقليم الوسط. و قد استُخدم أسلوب التحليل الاقتصادي القياسي لدوال تكاليف إنتاج الماعز و الأغنام و الأبقار في إقليم الوسط. و قد قُدر دوال تكاليف الإنتاج الكلية للأغنام ثم اشتقت دالة التكاليف الكلية المتوسطة و ذلك بهدف التوصل إلى السعة الاقتصادية و المحققة لتدنية التكاليف الإنتاجية المتوسطة. و قد بلغت قيمة الإنتاج قرابة 59.16649 دينار و بلغ عدد الرؤوس قرابة 419 رأساً، و بمتوسط تكلفة للدينار الواحد بلغت قرابة 522.0 ديناراً. كما اِشتُقت دالة التكاليف الحدية من دالة التكاليف الإنتاجية الكلية و بمساواة دالة التكاليف الحدية بالسعر المرجح، تم التوصل إلى السعة المحققة لتعظيم الربحية، حيث بلغت قيمة الإنتاج قرابة 49.18251 ديناراً و بلغ عدد الرؤوس قرابة 460 رأساً من الأغنام و بمتوسط تكلفة للدينار الواحد بلغت قرابة 56.0 ديناراً. و قد بلغت السعة الإنتاجية الحالية قرابة 157 رأساً و تقل هذه السعة عن نظيراتها المحققة للكفاءة الاقتصادية بقرابة 262 رأساً، كما تقل عن نظيراتها المحققة لتعظيم الربحية بقرابة 303 رأسا.
This research aimed to determine the economic scales of production and different product values, and the difference between the true sizes and its parallel economic areas in the midregion of Jordan. The econometrics analysis was used for the cost functions of sheep, goats, and cows production in midregion of Jordan. The data were analyzed by linear regression using suitable economic models. Total production functions of sheep were determined, and the average productivity was derived to determine the economic scales in order to minimize the average productivity cost of sheep, goats and cows. For the sheep, the product value was about JD 16649.59 for 419 sheep, with average cost of one JD is 0.522 JD. Marginal cost function was derived from the total production cost function, with the equality marginal cost function to parallel price in order to reach the scale of maximize profit. The production value was 18251.49 JD for 460 sheep and average JD cost of 0.56. The present productivity scale was 157sheep which was 262 sheep lower than the productivity scales for economic efficiency and 303 sheep lower than that for maximize profit.

The main objective of this study was to describe economic and econometric
analysis of cost functions of rain-feed barley production in the northern region
from Syria and determine the economically efficient size and the profitmaximizing
size, Prim
ary data collected in (2010) through research interviews
with farmers were used. Farms in the rainfed areas in. the northern region
were divided according to stabilization zones (1, 2, 3 and 4), Through the
descriptive economic analysis of costs of production of Farms in the rainfed
areas in the northern region were divided according to stabilization zones (1, 2,
3 and 4), Through the descriptive economic analysis of costs of production of
Barley, it was shown that the highest average cost of production of one dunum
in the northern region was 1859.3 sp. in zone (1) and the lowest average cost of
production of one dunum was 1694.5 sp. in zone (4), From the analysis of costs
and returns, the results indicated that the highest net return (profit) in the
northern region was 650.43 sp./dunum in zone (1), and the lowest net return
(profit) was 395.2 sp./dunum. in zone (3) Also, the results of the descriptive
economic analysis indicated that the lowest average cost of production of 1 kg
of barley was 8.3 sp. in zone (1 and 2), and the highest average cost of
production of 1 kg of oil was 9.3 sp. in zone (4), Using the econometric models
of cost functions, the economically efficient size and the profit-maximizing size
were computed and determined for each zone, indicating that farmers'
practices were too far from these sizes based on the econometric analysis;
namely the economically efficient size and the profit-maximizing size. Also the
results indicated that the economically efficient acreage size was 35.8 dunum in
zone (4), which was less than the actual area of this region.
The research aimed to estimate the total cost, medium and marginal
cost, volumes and economic optimization production of rain feed lentil in the
first zone of Aleppo governorate using econometric models. Linear regression
analysis of a single equa
tion was applied to explain the relationship between
amount of production as an independent variable and the value of production
costs as the dependent variable.
This study aimed to achieve the quantitive estimation of costs,
returns, efficiency and income economic indicators of sheep
breeding.
Tow sources of data were used ,Questionnaire of random sample
of breeders included (374 case) in the study area
as primary data
and MOAAR(annual agriculture statistical ), Database of NAPC,
as secondary data.
This research aims to conduct a descriptive and econometric
analysis of the costs functions of rain fed barley in the first, second and
third stabilization zones in Al - Hasakah governorate, and to determine
the optimum sizes for production and th
e profit-maximizing size. Data
were collected through a questionnaire for rain fed barley farmers in the
study area for the average season (2015 / 2016-2016 / 2017).
The aim of this research is the determination of the appropriate conditions
for extracting collagen by acidic method from remnants of skins of sheep, cows,
and chickens. The results showed that acetic acid is the best among the various
organic acids, for extracting collagen of these skins during 48 hours, at
concentration of 0.5 M and the ratio, acidic: skin (6:1).
