(Sher-e-Bangia Agricultural University Research System (SAURES), 2022-12) Islam, M. S.; Sarkar, S. K.; Hossain, M. M.; Masum, M. A.; Rahman, T.
Oral anti-diabetic agents have a number of serious adverse effects, thus, managing diabetes without any side effects is still a challenge. Therefore, the search for many effective and safer hypoglycemic agents has continued to be an important area of investigation. Besides, drug classically used for the treatment of diabetes (insulin, sulphonylureas, biguanides and thazolidinediones), several species of plants have been described in the scientific and popular literatures having a hypoglycemic activity. The aim of this research was to investigate the effect of Aloe vera on blood glucose level in rats in diabetic condition. In this study a total of 150 rats (50 normal rats and 100 alloxan induced diabetic rats) were used for five trials. The rats were divided into three groups for each trial, each containing 10 individuals as follows: Group A is the control, Group B as diabetic control and Group C were diabetic rat received Aloe vera. Then alloxan injection was injected at a dose rate of 100 mg/kg body weight through intra-peritoneal route to each rat to induce diabetes in groups B and C. Aqueous extract of Aloe vera were fed by gavage at a dose of 300 mg/kg body weight daily for 21 days in group C. On the 10th day blood glucose level and the body weights were measured for the first time to ensure diabetic induction. Then all the rats of this group were kept for more 21 days for the treatment of diabetic condition. During experimental period, day 0, 7, 14 and 21 blood samples were collected from all groups and determined their blood sugar level using diabetic kit. After 3 weeks of treatment the blood glucose level significantly (P<0.001) reduced in the group C compared to B from 260± 11.53 mg/dl to 91.21 ± 3.67 mg/dl. On the other hand, the average body weight was increased significantly (P<0.001) from 260 gm to 279.88 gm in the group C compared to that of B. From our findings, it is concluded that Aloe vera can be used as anti-diabetogenic agent in food.

(2011) Hossain, M. M.; Rahman, M. A.; Talukder, A. K.; Islam, M. S.
The study identified the common causes of organs and whole carcass condemnation of slaughtered sheep in a commercial abattoir in Bangladesh. A total number of 8046 sheep were slaughtered during the period from July 2007 to June 2008. Animals were undertaken into three ante-mortem inspections from arrival to slaughter. The first inspection was done immediately after unloading of animal, second during resting of the animals and the last inspection was performed before slaughtering of the animals. A total number of 703 organs from carcasses were condemned due to several reasons. The liver (42%) and lungs (39.1) were the most condemned organs in sheep. Fascioliasis was the leading cause of liver condemnation in sheep (86.8%). Pneumonia was the main cause of lung condemnations at the rate of 54.5% in sheep. Hydatidiosis caused both liver (6.4%) and lungs (40%) condemnation in sheep. Abscess was also responsible for organ condemnation affecting liver (6.8%), lungs (5.5%) and kidney (30.8%) in sheep. The major cause of muscles condemnation of sheep were due to cystocercosis (75.0%) and grass seed poisoning especially sorghum poisoning (25.0%).Grass seed poisoning was the only cause that was responsible for three sheep carcass whole condemnation. The results of the present study concluded that liver and lungs were the mostly affected organs to be condemned caused by mainly fascioliasis and pneumonia in sheep and grass seed poisoning was the single cause for whole carcass condemnation in sheep

(Dept. of CE, CUET, 19-Dec-2018) Hossain, M. M.; Islam, M. A.; Debanath, O. C.; Islam, M. S.
Bricks & sand are used in various types of construction work such as partition wall, reservoir, road & building. Problems frequently occur due to the use of low-quality bricks & sands. Bricks & sand that do not fulfil the quality standards make structures weak & faulty. Different field and laboratory tests are needed for quality control of these engineering materials. This study covers the experimental investigation sand and brick samples collected from ten different local areas of Chittagong district. These materials were tested through field and laboratory tests to assess their engineering properties in order to compare with standard limiting values. Unit weight, Fineness modulus, Salinity, Water Absorption Capacity, Specific gravity and Chloride tests were conducted for sand. Whereas Field Test, Size & Shape, Salinity, Chloride, Unit Weight, Water Absorption and Crushing Strength tests were performed for Bricks in the laboratory of Chittagong University of Engineering and Technology. The properties of brick and sand samples are observed to vary for different sources. However, the test data may provide necessary information to ensure quality of construction works in this region.

(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2014-07) Alam, M. J.; Beg, M. A. H.; Hossain, M. M.
Moringa (Moringa oleifera Lam. moringaceae) is a highly valued plant that is mostly cultivated in the tropics and subtropics. It is used for food, medication and industrial purposes. The objective of the study was to assess the nutritional value of Moringa leaves and to determine the effect of supplementing Moringa oleifera leaves (MOL) on growth performance, carcass and non-carcass characteristics of Black bengal goats. The dried leaves had crude protein levels of 30.3%. Thedried leaves had the following mineral contents: calcium (3.65%), phoshorus (0.3%), magnesium (0.5%), potassium (1.5%), sodium (0.164%), sulphur (0.63%), zinc (13.03 mglkg), copper (8.25%), manganese (86.8 mglkg), iron (490 mglkg) and selenium (363 mg/kg). The fiber content was neutral detergent fibre (NDF) (11.4%), acid detergent fibre (ADF) (8.49%), acid detergent lignin (ADL) (1.8%) and (acid detergent cellulose (ADC) (4.01 %). The condensed tannins had a value of 3.2%, while total polyphenols were 2.02%. In the other hand, a total of 36 castrated goats aged 8 months, with a mean initial weight of 7.63±O.8 kg, were randomly divided into three diet groups with twelve goats in each. The duration of the trial was 90 days. All goats received a basal diet of grass ad libitum and mixed basal diet (200 g/day each). The MOL groups were fed additional lOOg (MOLl) and 200 g (MOLZ) of dried M. aleifera leaves, respectively. The third group (Control) did not receive any additional ration. The attained average daily weight gain for goats fed MOLl, MOL2 and Con were 103.3, 101.3 and 43.3 g, respectively (p<0.05). Higher (P<0.05) feed intakes observed were in MOL2 (491.5 g) and MOLl (490.75 g) compared with Con (404.5 g). The hot carcass weight was higher (p<0.05) for MOL2 (7.18 kg) and MOLl (7.14 kg) than for the Con group (5.46 kg). The dressing percentage in MOL2 (50.8%) and MOLl (50.0%) were higher (P<0.05) than that of the Con (44.9%). The growth performance and carcass characteristics of MOL2 and MOll goats were not different. Moreover the experimental result reveal that MOL has a cholesterol lowering effect and no lesion has been identified in the gastrointestinal mucosa of the parasitized animals fed on MOL mixed diet. Feeding MOL improved the growth performance and carcass characteristics of goats in an almost similar way, which indicates that M. oleifera could be used as a supplement or additives in goats.

(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2011-01) Hossain, M. M.; Islam, M. K.; Rahman, M. A.; Talukder, A. K.; Islam, M.
This study identified the common causes of condemnation of slaughtered cattle and goat in a commercial abattoir in Bangladesh. A total of 8,604 cattle and 27,699 goats were slaughtered for the period of July 2007 to June 2008. All the procedures of standard abattoir were followed to get hygienic meat. Ante-mortem examination and postmortem inspection was done with due attention. In cattle liver and lungs are first list organs for condemnation and incidence of affection is 78% in liver and 19.3% in lungs. Fascioliasis is the leading cause of liver condemnation in cattle (75.5%). Hydatidosis affection found both in liver and lungs but the incidence rate is higher in lungs. Abscess is also a disease responsible for organ condemnation particularly in liver (1.4%), lungs (6.1%) and kidneys (I. I%). In goats, a total of 7,278 organs were condemned due to several diseases or conditions namely fascioliasis, hydatidosis, cysticercosis, abscess, pnemonia and tumor. Among them 5,55 I cases were liver (76.3%) and 1,296 cases were lungs (17.8%). Fascioliasis is the leading cause of liver condemnation in goat (94.8%) where pneumonia is for lungs condemnation (69.5%) in goat. However hydatidosis cause both liver (4.6%) and lungs (23.2%) damage at the point of condemnation. Liver, lungs and kidneys abscess are responsible for organ condemnation. Cysticercosis (16.3%), gluteal abscess (15.6%) and grass seed poisoning (6.4%) are also the causal factors of condemnation. The results suggested that the highest incidence of organ condemnation is found in liver and lungs caused by fascioliasis and pnemonia in cattle and goats respectively and grass seed poisoning is the single cause for whole carcass condemnation in goat. The results of the present study concluded that liver and lungs are organs of various affections and mandatory to condemn.

(Sher-e-Bangla Agricultural University Research System, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, 2007-07) Wadud, M. A.; Alam, M. J.; Beg, M. A. H.; Hossain, M. M.
The study was conducted to determine the effects of dietary supplementation of a commercial probiotic (Protexin) on daily feed consumption, egg yield, egg weight, feed conversion, external and internal qualities of egg and livability in layer hens. To achieve the objectives a total of96, 42 weekold layers arranged in four dietary treatment groups including control, containing 8 birds! replication supplemented with 0, 0.5, 1.0 and 1.5% probiotic for a period of 16 weeks. The study reveals that the hen day egg production, feed conversion, egg weight and mass, egg shell weight, egg thickness and egg breaking strength increased linearly with the use of dietary protexin. However, livability and internal egg quality were not altered with the use of dietary protexin. Present study concluded that dietary supplementation of probiotic promote the laying performance and most of the external quality characteristics of eggs. In conclusion, it is recommended that dietary supplementation of probiotic at the rate of 1.5 gm per kg feed in the layer ration may be economically potential.
