The present study was planned to examine digestible amino acids (DAA) and apparent metabolizable energy corrected for nitrogen (AMEn) of the commonly used indigenous poultry feed resources, and their effects on the performance of Cobb (500), Arbor Acre and Hubbard (Classic). The study comprised of three phases. In the first phase, standardized ileal amino acid digestibility (SIAAD) of 3 samples of each feed ingredient was determined in broilers at the age of 21 days. The test ingredients served as sole source of AAs in their respective diets. The diet based on each sample of each ingredient was fed to 36 birds in 6 replicates, each containing 6 birds. The acid insoluble ash (AIA), at the rate of 2% of the diet, was used as an external marker to determine digestibility. Among cereals, the corn had the highest SIAAD (90.11%) and among cereal by-products, wheat bran exhibited higher SIAAD (76.86%). Among protein meals, soybean had the highest digestibility but it was the lowest in guar meal. In the second phase, the AMEn of 3 sample of each feed ingredient was determined by substitution method in 21 days old broilers using AIA, at 1% of the diet, as an external marker. Among cereals, rice broken had the highest AMEn (3372 kcal/kg). Similar in cereal byproducts, rice polishings supplied the highest AMEn (1936 kcal/kg). The fish meal exhibited highest AMEn (2802 kcal/kg) in protein meals. In the third phase, 3 diets for each strain were formulated using DAA coefficients and AMEn values determined in first two phases to examine the growth performance of three broiler strains. The control diet (C) had standard DAA according to each strain’s requirement. The second diet (HDAA) supplied 10% more DAA and the third diet (LDAA) had 10% less DAA than C. Data were analyzed using Completely Randomized Design (CRD) having levels of DAAs nested within broiler strains. The growth performance of Arbor Acre at 42 days of age was better (P<0.05) followed by Hubbard and Cobb. All 3 strains of broilers fed LDAA diet ate more (P>0.05) feed and gained numerically more (P>0.05). Similarly, improved feed conversion ratio (P>0.05) was noticed in Cobb fed HDAA diet. However, Arbor Acre and Hubbard performed better on C diet. Dressing percentage remained similar among all diets in all strains; but, breast meat percentage improved (P>0.05) when fed HDAA diet in all strains. In conclusion, determining nutrient availability of locally available feed ingredients will not only help maintain national database repository but will also help cost-effective broiler production in the country.

پیر عبدالقادر

پیر عبدالقادر ؒ
)دین پور شریف والے(
پیر اساڈے عبدالقادر جیہڑے دین پور والے
دین نبیؐ دی خاطر جنھاں لکھاں دکھڑے جالے
شاہ عبدالرحیم تے عبدالقادر نے سب کرم کمایا
خواجہ اللہ بخش نے یارو فیض انہاں توں پایا
جٹو والے ٹبے اُتے تنبو دین دا لایا
دین دے اس چشمے توں لوکی بھر بھر پین پیالے
خواجہ اللہ بخش بہاولنگر چ قدم ٹکایا
دین دی روشنائی نوں ایتھے آپ نے سی پھیلایا
جٹو والہ بنیا مرکز، دین پور نام رکھایا
جگ وچ دھماں پیاں ہر کوئی دین پور نوں بھالے
حضرت دے رہے بیٹے دونویں درس قرآن پڑھاندے
شرع و حدیث تے فقہ فقر دے دیوے رہے جلاندے
لنگر پانی ہر اک نوں اوہ گھروں رہے کھواندے
شہر محلے کوچے گلیاں چرچے ہون دوبالے

حضرت یحییٰ پوتے سن جو ، بہتی شہرت پائی
جس تے نظر کرم دی کردے دل دی کرن صفائی
ذکر اذکار تے عشق نبی ؐ وچ فقر دی جوت جگائی
ایویں فیض روحانی ملدا جوں مینھ وچ ویہن پرنالے
شکل شبہات سی آپ دی ایسی من چ اتردی جاوے
ویکھے جیہڑا ول ول ویکھے فر وی صبر نہ آوے
چولا آس، رومال دا گھونگھٹ ، حضرت نوں بھاوے
دلوں بجانوں منیا جہناں بن گئے دین دے رکھوالے
حضرت جی دے بیٹے سارے پیار بھرے نے بھائی
ایہناں وچوں پیر عبدالقادر بہتی شہرت پائی
کرے دعا تے ہووے شفاء رب سوہنے گل بنائی
جہڑے در تے آون رب دکھ انہاندے ٹالے
قادری سائیںؔ در انہاں دے بہہ کے فیض کمائیے
جئے کر صدق یقین تھیں بہئے کدی وی تھوڑ نہ پائیے
رب کرے در اوہناں دے اسیں سارے آئیے جائیے
جہیڑا اوہناں دے...

The Existence of Gorontalo Muhammadiyah University in Increasing the Income of the East Pentadio Village Community

The purpose of this research was to determine the existence of the Muhammadiyah University of Gorontalo in increasing the income of the people of East Pentadio Village. This research uses a descriptive qualitative research approach, using interview instruments with various informants. The results using Samuelson's theory about the factors that influence income, show that the existence of the Muhammadiyah University of Gorontalo is able to increase the income of the people of East Pentadio Village. However, the current existence of the campus has not been fully utilized by the community in increasing the income of the people of East Pentadio Village. There are still many outsiders who take advantage of the opportunity of the existence of the Muhammadiyah University of Gorontalo by making larger businesses in the campus area so that community businesses that are built simply with little capital experience competition. The low level of education of rural communities makes the business that is built still not optimal and makes the community less creative and innovative in entrepreneurship. This also causes people to easily give up when experiencing losses.

Financial Liberalization and its Impact on Economic Growth of Pakistan

This dissertation is an attempt to contribute theoretically and empirically in the area of research regarding financial liberalization and economic growth for Pakistan. On account of growing importance of financial liberalization in the promotion of growth in the developed and emerging economies and dearth of significant literature on this topic in the case of Pakistan, the present study examines the impact of financial liberalization on economic growth. The thesis investigates both the domestic and external components of the financial liberalization process and their impact on economic growth of Pakistan. The dissertation in particular develops an index of domestic financial liberalization using the technique of principal component analysis. The index captures the important dimension of reform process and quantifies the impact of domestic financial liberalization on growth. The external financial liberalization is examined through the de jure and de facto measures of external financial liberalization. The dissertation develops a quantitative measure of external financial openness through de jure approach on the basis of information under the capital account liberalization. The de facto measure of external financial liberalization is based on the work of Lane and Ferretti (2006) while the data for remaining years are updated utilizing their methodology. A joint impact of both the domestic and external components of financial liberalization (showing an overall impact of financial liberalization on growth) is also examined through the measure of domestic financial liberalization index and de facto measure of external financial liberalization. The results of the study indicate a positive impact of composite index of domestic financial liberalization on economic growth. External financial liberalization when measured through de jure approach positively impacts economic growth. However, the de facto measure shows a negative association between external financial openness and economic growth. The empirical results finally report an overall positive impact of financial liberalization on economic growth examined by including both the domestic and external components of financial liberalization. The positive impact of financial liberalization on economic growth is on account of financial intermediation, financial deepening and easy access to capital brought through domestic and external liberalization. However, to get more pronounced benefits out of liberalization process, financial sector needs more strengthening both at the domestic and external fronts.
