Three independent studies using male Kajli lambs at post-weaning, growing and finishing stages were designed and undertaken to examine the effect of different protein sources with or without probiotics on growth performance and carcass characteristics. In the trial I, 32 male Kajli lambs at three months age were randomly divided into eight groups of four animals each in a 4×2 factorial arrangement. Four iso-caloric (70% TDN) and iso- nitrogenous (22% CP) diets were formulated with four different protein sources i.e. corn gluten meal 30% (CGM), canola meal (CM), cotton seed meal (CSM) and sunflower meal (SFM) containing either 0 or 50g of probiotics (Protexin®)/ ton of feed. In trial II and III, lambs were again randomized and given the same treatment as in trial I. However, crude protein (CP) content of diets was reduced from 22 to 18% in trial II and 18 to14% in trial III. In trial I, higher (P<0.05) dry matter (DM) and CP intake, DM, CP, neutral detergent fibre (NDF) and acid detergent fibre (ADF) digestibility, blood glucose, N-balance and total weight gain were observed in lambs fed CM diet than those fed CGM, CSM and SFM diets. However, blood urea nitrogen (BUN), creatinine and serum minerals remained unaltered (P>0.05) in lambs fed diets containing different protein sources. Neutral detergent fibre and ADF digestibility and blood glucose was higher (P<0.05) in lambs fed diets containing probiotics. Dry matter and CP intake and their digestibility, BUN, creatinine, serum minerals, N-balance and total weight gain remained unaltered (P>0.05). In trial II, higher (P<0.05) DM and CP intake, blood glucose, N-balance and total weight gain were noticed in lambs fed CM diet than those fed CGM, CSM and SFM diets. However, diets containing different protein source didn’t affect (P>0.05) the DM, CP, NDF and ADF digestibility, BUN, creatinine and serum minerals. Neutral detergent fibre and ADF digestibility and total weight gain was higher (P<0.05) in lambs fed diets containing probiotics. However, diets containing probiotics didn’t influence (P>0.05) DM and CP intake, DM and CP digestibility, BUN, blood glucose, creatinine, serum minerals and N-balance. In trial III, higher (P<0.05) DM and CP intake, N-balance and total weight gain were observed in lambs fed CM diet than those fed CGM, CSM and SFM diets. However, DM, CP, NDF and ADF digestibility, BUN, blood glucose, creatinine and serum minerals remained unaltered (P>0.05) in lambs fed diets containing different protein source. Acid detergent fibre digestibility and total weight gain was higher (P<0.05) in lambs fed diets containing probiotics however, DM and CP intake, DM, CP and NDF digestibility, BUN, blood glucose, creatinine, serum minerals and N- balance remained unaffected (P>0.05). Hot carcass weights of lambs differed significantly (P<0.05) in lambs fed diets containing different protein sources with or without probiotics. However, dressing percentage (DP) and skin, feet, heart, liver and lungs weight remained unaltered (P>0.05) across all the treatments. The higher DP was observed in lambs fed CM diets, whereas it was lower in lambs fed SFM diet. Leg, loin, shoulder, breast and neck weights of the half carcass of the lambs remained unaffected (P>0.05) across all the treatments. Crude protein content of carcass was different (P<0.05) in lambs fed diets containing different protein source with or without probiotics, while moisture, ether extract and ash contents remained unaltered (P>0.05) across all treatments. The ratio of lean, fat and bone in primal cuts of half carcass (neck, shoulder, breast, loin and leg) remained unchanged (P>0.05) across all the treatments, except for the proportion of lean in shoulder, bone in loin and fat in legs, which was affected (P<0.05) by the diets containing different protein sources. In short, the lambs fed CM diets performed better than those fed CGM, CSM and SFM diets in all the three trials. Diets containing probiotics improved weight gain in trial II and III but not in trial I.

نواب اسمٰعیل خاں مرحوم
یہ سطور زیر تحریر تھیں کہ نواب اسمٰعیل خاں مرحوم کی وفات کی خبر ملی، مرحوم ایک بڑے باپ نواب اسحق خاں کے لڑکے اور ایک نامور دادا نواب مصطفے خاں شیفتہ کے پوتے اور خود بھی بہت سے اوصاف سے متصف، قدیم تہذیب و شرافت کا نمونہ تھے، قومی و ملکی سیاست سے بھی ان کو دلچسپی تھی، چنانچہ خلافت کی تحریک کے زمانہ میں وہ کانگریس کے ساتھ اور ہندوستان کی جنگ آزادی میں عملاً شریک رہے، مگر اس زمانہ میں بھی ان میں بڑی دینی و ملی حمیت تھی، غالباً اسی بناء پر پاکستان کے قیام کی تحریک کے بعد مسلم لیگ میں شامل ہوگئے، وہ اس کے مقتدر رہنما اور فطرۃً نہایت سنجیدہ متین اور باوقار تھے، اس لئے ہر زمانہ میں ان کی روش معتدل رہی اور وہ جس جماعت میں بھی رہے ان کی حیثیت امتیازی رہی اور ان کا خاص وزن و وقار رہا، گو وہ لیگ کے لیڈر تھے، مگر ہندوستان کی تقسیم کے بعد انھوں نے پاکستان کی راہ نہیں لی، بلکہ ہندوستان ہی میں رہ کر یہاں مسلمانوں کے درد دکھ میں شریک رہے، کچھ دونوں تک مسلم یونیورسٹی کے وائس چانسلر بھی رہے تھے، ان کی موت سے ہماری قدیم تہذیب و شرافت کی ایک باوقار یادگار مٹ گئی، اﷲ تعالیٰ اس خادم ملک و ملت کو اپنی رحمت و مغفرت سے نوازے۔

نواب محمد اسمٰعیل خاں مرحوم
( پروفیسر رشید احمد صدیقی)
نواب محمد اسمٰعیل خاں، نواب محمد اسحق خان کے بیٹے اور نواب مصطفےٰ خاں شیفتہ کے پوتے تھے، شیفتہ کو دیکھا نہیں، لیکن ان کی غیر معمولی ذہنی اور اخلاقی خوبیوں کا حال کتابوں میں پڑھا ہے، شیفتہ کی بڑائی میں کیا شک جب حالیؔ اس پر گواہی دیتے ہوں۔

Dietary Options in Irritable Bowel Syndrome Irritable Bowel Syndrome & Die1

Irritable bowel syndrome (IBS) is thedisease condition in which our gastrointestinal(GI) tract is affected and cause abdominal pain and discomfort that is associated with change in the stools form and frequency. In this condition one may suffer from diarrhea, constipation or both at the same time. This disorder is very common now days because of unhealthy eating habits mostly in females. Manyfactors are responsible for IBS like food, environment, genetic and psychological factors. IBS can be overcomed by improving our eating habits and lifestyle and also by following different diets like FODMAP and GLUTEN FREE diet. Probiotics and herbs are also very beneficial in curing IBS.

Production of Fungal Treated Wheat Straw Through Solid State Fermentation and its Biological Evaluation in Nili Ravi Buffalo Calves

The poor availability of high quality feedstuff and consistent use of abundant low quality dry roughages as an animal feed are the major constraints in the development of livestock sector in Pakistan. For an efficient exploitation of available crop residues like wheat straw, biotechnological methods along with solid state fermentation technology using Arachniotus sp. were employed to upgrade its nutritive value in laboratory and on large scale at farm. Thus at both levels, addition of salts (MgSO4.7H2O, CaCl2, KH2PO4 andurea) and industrial residues (molasses, rice polishing and corn steep liquor) highly increased the crude protein contents and decrease the neutral detergent fiber, acid detergent fiber and acid detergent lignin in the fermented wheat straw. It was demonstrated that Arachniotus sp. are a potential alternative fungi that on addition of economical by-products provide more practical and environmental-friendly approach for enhancing the nutritive value of wheat straw on large scale at farm level. Moreover, the biological trial of this treated wheat straw in Nili Ravi male buffalo calves considerably increased the dry matter intake, daily weight gain, improved feed conversion ratio, an enhanced feed economics and nutritive digestibility. Hence, the current observations highly endorse the use of these economical by-products for cheap biomass production from low quality dry roughages and it was recommended to add this improved feed in livestock ration for an enhanced growth performance.
