Sohail H. Khan,Jehanzeb Ansari,Ahsan u. Haq,Ghulam Abbas
Italian Journal of Animal Science , 2012, DOI: 10.4081/ijas.2012.e77
Abstract: A study was conducted to evaluate the effect of 3 different levels (1.25, 2.5 or 5.0%) of black cumin seeds (BCS) on five hundred chicks. A basal diet was supplemented with either 0 (negative control), or 0.1% antibiotic (positive control), or 3 levels of BCS. At day 28 and 42 of age, the 2.5 and 5.0% BCS groups had significantly greater body weight gain (BWG) than the 1.25% BCS and the antibiotic group. The same groups had feed efficiency significantly improved (P<0.05) compared to the 1.25% BCS group and the controls. At both ages, measurement of the dressing percentage showed no marked variation between BCS supplementation and antibiotic. The 2.5 and 5.0% BCS groups showed an increase (P<0.05) in total protein and higher (P<0.05) haematological values than the 1.25%, antibiotic or unsupplemented diet group. The activities of blood enzymes were lower (P<0.05) and caecal coliform and Escherichia coli populations decreased (P<0.05) in BCS and antibiotic groups. Serum and tissue cholesterol concentration decreased (P<0.05) as the levels of BCS increased. The geometric means haemagglutination inhibition (HI) titres of the BCS and the antibiotic group were always higher than the negative control. The mean lymphoid organs weight/body weight ratio of the negative control was significantly (P<0.05) lower than BCS and antibiotic groups. In conclusion, including up to 2.5 or 5.0% BSC in the diets of broilers has no deleterious effects on their performance, immunity, serum biochemical constituents nor haematological indices. In fact, it may lead to the development of low-cholesterol chicken meat.

Shakeel Ahmad,Ahsan- ul-Haq,Muhammad Yousaf,Haq Nawaz
Pakistan Journal of Nutrition , 2010,
Abstract: Two hundred and forty White Leghorn laying hens at 48th week of age were randomly divided into 24 experimental units. These experimental units were allotted to eight treatment groups which were fed diets with 0, 2, 3 and 4% canola oil with 3000 or 10000 IU vitamin A/kg of diet (4 x 2 factorial design), for a period of 12 weeks in order to observe the effects of feeding canola oil and vitamin A on the fatty acid profile of egg yolks. Two eggs per replicate were collected at the end of trial and analyzed for fatty acid contents of egg yolks. The increase in dietary canola oil levels increased (p<0.001) both n-6 and n-3 Polyunsaturated Fatty Acids (PUFA) but the increase in n-3 PUFA was more pronounced. The n-6/n-3 ratio decreased with the increase in dietary canola oil levels. However, the increase in dietary vitamin A level did not influence (p>0.05) the egg yolk fatty acid composition.

Hafiz Munir Ahmed,Ghulam Sarwar,Muhammad Ahsan ul Haq
Songklanakarin Journal of Science and Technology , 2012,
Abstract: Morphological data pertaining to different attributes were recorded in M4 and M5 generations of gamma irradiatedcastorbean to study correlations, path analysis and some genetic parameters. Significant and positive correlation of capsuleyield per plant with seed yield was observed. Hundred seed weight showed positive but non significant phenotypic andsignificant genotypic correlation with seed yield. Capsule yield per plant also showed high direct effect combined with highpositive and significant genotypic correlation. Number of capsules of main spike, main spike length and number of spikesper plant showed high heritability coupled with high genetic advance which revealed the preponderance of additive genesand seed yield could be improved via these traits. However, length of spike and 100-seed weight may also be considered forimprovement in seed yield. On contribution of different morphological traits, 16 mutants yielded higher than the check, however,the maximum seed yield per plant (mean of 02 years) was gained by CBM-7 (209.54 g) followed by CBM-17 (183.35 g)as against the check DS-30 (126.75 g). These prospective mutants can be tested for genetic stability and adaptability overdifferent locations for variety release programme in the country.
Vegetative Propagation of Chickpea (Cicer arietinum L.) Through Stem Cuttings
Hina Syed,M. Ahsan- ul- Haq,T. M. Shah
Asian Journal of Plant Sciences , 2002,
Abstract: Chickpea stem cuttings were used for vegetative propagation to multiply wild Cicer species and F1 hybrids produced from intraspecific hybridization. Stem cuttings of three varieties were treated with different concentrations of root inducing hormones NAA and IAA to compare and standardize the optimum concentration of these hormones. Three different concentrations (0.25, 0.5 and 1 mg l-1) of NAA induced 100 % rooting within ten days in all varieties. Wild Cicer species and F1 hybrids with less number of seeds were treated with 0.5 mg l-1 of NAA. About 10-13 plants were produced from every F1 seed. All plants performed well in the field and produced sufficient quantity of seed.

Sanjana Zaman, Mohammad Delwer Hossain Hawlader, Animesh Biswas, Mahmudul Hasan, Mobashera Jahan, Gias U Ahsan
Health (Health) , 2017, DOI: 10.4236/health.2017.912123
Abstract: Background: Recent studies suggested that vitamin D deficiency among children is widespread worldwide. Most of the Asian countries are suffering from high prevalence of vitamin D deficiency, especially in children. However, the vitamin D deficiency of Bangladeshi children has not been investigated yet. The objective of the study was to assess the prevalence of vitamin D deficiency among children in Dhaka city, Bangladesh. Methods: A cross-sectional study was designed. Children aged 0 month to 16 years attended Pediatrics’ clinics with minor illness were conveniently recruited. After obtaining informed written consent, venous blood was taken and serum 25(OH)D levels were determined by direct enzyme-linked immunosorbent assay. Descriptive statistics were performed for age, sex, biochemical parameters. Socio-economic status (SES) was estimated using a wealth index, producing a weighted score. Scores were categorized into quintiles, with category 1 representing the poorest and category 5 the richest. Serum 25(OH)D was categorized: deficient as <10 ng/ml, insufficient as 10 - 29 ng/ml and sufficient as 30 - 100 ng/ml. Results: 31.88% children of 0 - 1 year had deficient serum 25(OH)D level and 52.17% children had insufficient level. Among 2 - 5 years’ group, 38.16% were deficient and 50% were insufficient. Among the 6 - 11 years group, 41.02% were deficient and 52.56% were insufficient. Among 12 - 16 years group, 46.75% were deficient and 51.95% were insufficient. That means, serum 25-hydroxyvitamin D deficiency and insufficiency rate is found very high among Bangladeshi children. Conclusions: The prevalence of vitamin D deficiency and insufficiency among children in Bangladesh is high. The study recommended that vitamin D supplementation in Bangladeshi children should be formally launched from first day of birth up to adolescence.

Health (Health) , 2018, DOI: 10.4236/health.2018.101007
Abstract: Chikungunya occurred as a major epidemic form in Bangladesh in 2017 after a gap of 6 years. The first outbreak of Chikungunya was identified in Bangladesh in 2008. Another outbreak occurred at Dhaka in 2011. But the current outbreak is huge and effecting almost two third of the population. Methods: This was a retrospective case series study, consisted of 60 children, among which 35 were male and 25 female, ages ranging from 5 to 15 years. Those children were recruited from child health care clinic with a history of two to five days’ high grade fever. All patients recruited were IgM antibody for Chikungunya positive (after 5th day of onset of fever) and on the other hand antibody for Dengue was negative. Two patients were excluded from the study due to Cerebral Palsy and Claustrophobia. Finally 58 patients were assessed. Informed written consent was obtained from all the legal guardians before data collection. Results: All patients presented with a history of two to five days’ high grade fever. The fever was preceded by a maculopapular rash over the trunk and extremities, headache, myalgia and arthralgia. Delirium (non-specified) was most prevalent psychiatric symptoms 45 (77%). Other psychiatric symptoms were Panic Disorder (56%), Phobic Disorder (36%), Neurasthenia or Fatigue syndrome (27%), Hypersomnia (13%) and Claustrophobia (5%). Conclusion: This study suggested that psychiatric morbidity among pediatric Chikungunya patients is very common. Knowledge of the pathogenesis is required to reduce the psychiatric complications and to prevent the morbidity. There is an emergence to invent the prophylactic vaccination, proper and early diagnosis of Chikungunya.

Fawwad Ahmad, Ahsan-ul-Haq, M. Ashraf, Jibran Hussain and M. Zubair Siddiqui
Pakistan Veterinary Journal , 2010,
Abstract: A study was conducted for eight weeks to determine the effect of different light sources on the production performance of egg laying birds. For this purpose, 384 single comb White Leghorn layers 40-weeks of age, in their first laying cycle, were obtained from the Poultry Research Centre, University of Agriculture, Faisalabad, Pakistan. The layers were randomly divided into 12 basic experimental units comprising 32 laying hens each, to be designated as replicate. These 12 replicates were further divided into three treatment groups viz; A (fluorescent), B (compact fluorescent), and C (incandescent), each comprising 128 layers. Production performance of birds under different treatments was compared in terms of body weight, feed consumption, egg production, feed conversion ratio, mortality and economics. Hen-day egg production (%) was significantly higher (P<0.05) in groups B and C compared to group A. Analysis of data on feed conversion ratio showed that layers in group A and B were significantly less efficient in feed conversion compared to those of group C; difference between the former two groups was non-significant. However, light sources showed non-significant effect on feed consumption, body weight and mortality of the birds. Birds of group B fetched more profit than those of groups A and C.

Z. Kamran, M. Aslam Mirza, Ahsan-ul-Haq1 and S. Mahmood1
Pakistan Veterinary Journal , 2004,
Abstract: A six-week trial was conducted to study the effect of decreasing dietary crude protein (CP) level on the performance of broilers in hot climatic conditions. Four experimental rations having CP 23 (control group), 22, 21 and 20%, with optimal amino acid balance were prepared. All the four rations were isocaloric having ME 3200 kcal/kg with Energy: Protein (E:P) 139.0, 146.5, 152.4 and 160 in diets A, B, C and D respectively. One hundred and twenty day-old chicks were randomly distributed into 12 experimental units, each having 10 chicks. Rations were randomly allotted to experimental units such that each unit received three replicates. The experimental diets were fed to birds from day 1st to 42nd. Performance of birds was monitored in terms of weight gain, feed consumption and feed conversion ratio (FCR). At the end of experiment, two birds per each replicate were randomly selected and slaughtered to record the data on carcass yield, breast meat yield, abdominal fat and composition of breast meat. Results of the trial suggested that weight gain was significantly (P<0.01) increased in birds on diets with CP 20 and 21%. Feed consumption and FCR remained un-changed for all the treatment groups. Eviscerated carcass yield was significantly (P<0.05) higher for the group fed on diet with 20% CP. Breast meat yield, abdominal fat and composition of breast meat also remained un-changed. Economic evaluation of the trial revealed that decreasing CP levels from 23 to 20% resulted in reduced feed cost per kg of live weight gain, which clearly indicated that this approach was useful especially in severe summer conditions. The overall picture of the study suggests that dietary protein level of broilers could be reduced from 23 to 20%, with beneficial effects on growth performance and carcass characteristics and increased economic returns in hot environmental conditions, provided that levels of essential amino acids are closely looked after.
