2008-06-01T00:00:00Z

DIFFERENTIATION OF WHEAT VARIETIES THROUGH MORPHOLOGICAL AND MOLECULAR APPROACHES TASNUVA, SHARMIN - E—- Genetic variation within species has been assessed by many methods and from several perspectives. In present thesis, both RAPD markers and morphology were successfully used to differentiate four cultivars of wheat named Bijoy, Prodip, Sourav and Shatabdi. Four distinct morphological characters were identified to differentiate four varieties. In lower glume beak length, at physiological maturity stage, distinctness was observed. In Bijoy it was almost rudiment (1-2mm), in Prodip its length was the highest (15-18mm), in Shatabdi it was medium 12-15mm and in Sourav it was small (8-10mm). In Zadok growth stage 25-29, a distinct difference was observed in four wheat varieties. Growth habit of Sourav was erect, Shatabdi semi-erect and Prodip intermediate. Heading days at Zadok growth stage were 68 for Sourav, 71 for Shatabdi, 63 for Bijoy and 60 for Prodip. Clum glaucosity was strong in Sourav, weak in Shatabdi and Prodip and medium in Bijoy. Among the eleven primers initially tested, two primers (OPA-02 and OPB-01) yielded comparatively higher number of amplification products with high intensity, minimal smearing and good resolutions with clear bands. All of them (100 %) were considered as polymorphic and no monomorphic band was found the primer OPA-02 produced 16 bands and the other primer OPB-01 generated 17 bands respectively. The present experiment produce 33 scoreable bands by using two primers (OPA-02 r produced 16 and OPB-01 produced 17 bands) and they were polymorphic RAPD markers. The result of RAPD marker was more distinct than the morphological marker for the differentiation of wheat varieties. Phenotypic characters were influenced by the environment but incase of molecular marker the reproducibility of RAPD markers were the same in the same reaction conditions. So RAPD marker was found as a potential, simple, rapid and reliable method to evaluate the genetic variation.

EFFECTS OF ALOE VERA EXTRACT IN DRINKING WATER ON BROILER PERFORMANCE RAJIB, MD. MIRAJIL ISLAM This experiment was conducted to evaluate the effects of dietary supplementation of aloe vera extract (w/v) on growth performance of broiler. The present study explored the potentials of medicinal plants Aloe barbedensis mixture in broiler performance. For this purpose 120 day old chicks were randomly assigned into five treatment groups, namely To, T,, T2, T; and Ty. Each treatment group contained 24 chicks .The chicks were purchased from a local chick hatchery named Nourish Poultry & Hatchery Ltd. Birds were brooded up to 10 days and then reared in separate flock for 35 days in an open sided house. Each treatment group was further replicated into three sub-groups and each contained eight birds. Experimental birds in T), T2, T3 and T, were provided with aloe vera extract (w/v) @ 05, 10, 15 and 20 ml per liter of drinking water while To was maintained as control group. Relevant data were recorded throughout the experimental period and subjected to statistical analysis. The data on growth parameters (body weight gain, feed consumption, feed efficiency, water intake) and feed cost and gross return per broiler were evaluated. The results of the study revealed that the aloe vera supplemented groups showed higher live weight gain than untreated group. Aloe vera supplemented groups showed more live weight gain in the terminal stages of the experiment. Aloe vera (w/v) extract supplemented groups performed the best feed efficiency. The live weight gain and feed efficiency were significantly (P<0.05) better in the broilers provided water containing 15 ml/L aloe vera aqueous extract. Water intake, feed intake and abdominal fat deposition of broilers given aloe extract in drinking water were not different among each other. So, 15 ml/L aloe vera aqueous extract may be given to the broilers drinking water. EFFECTS OF ALOE VERA EXTRACT IN DRINKING WATER ON BROILER PERFORMANCE A THESIS By MD.

PRESENT STATUS OF SMALL HOLDER DAIRY FARMS IN DINAJPUR DISTRICT AMIN, MD. NURUL The present study was assigned to determine the present status including general information, feeding, breeding, housing, milking, health management, factors related with milk production and problems faced by dairy farmers and overall make recommendation for the development of small scale dairy farms. The empirical data were collected by using pretested questionnaire. The study was conducted at 5 Upazilla’s in Dinajpur District for six months on hundred small dairy owners. Higher percentage of farm owner education was found High school level (29%). It was observed that 19 percent farm owner’s were illiterate and rest were educated. Among the total farmer's only 38 percent choose dairy as main business and rest 62 percent are engaged with side business. The 94 percent farmers had herd size of 3-5 cows and 71 percent farmers reared their cows in semi-intensive system. Hygienic management of houses are done only by 43 percent farmers and rest 57 percent farmers did not manage their cows shed hygienically. It was observed that 17 percent farmers did not use any protein and fat sources in the ration but 100 percent farmers used different types of carbohydrate concentrate feeds, grass, straw and tree leaves as feeds. Most of the farmers 76 percent used vitamin and mineral as supplement and only 10 percent farmers used treated roughage. Only 52 percent farmers maintain the udder management hygienically and washed udder before milking. Only 40 percent farmers used artificial insemination, 16 percent used natural breeding and 44 percent used both natural and Al. Daily average milk yield/cow was 4.27+0.40 and 1.78+0.25 liters for a crossbred and indigenous dairy cow, respectively and the milk production was significantly (p<0.01) higher in cross bred than the indigenous cows. Milk production was significantly (p<0.05) higher in adult age and moderate parity (6.31+2.39 liter daily per cow) than young adult and few parity (5.25+1.98 liter daily per cow) and old age and many parity (5.90+2.41 liter daily per cow). Milk production was significantly (p<0.05) higher in the farms that milked cows twice daily (2.05+1.06 liter daily per cow) than the farms that milked cows once (1.05+0.47 liter daily per cow). Milk production was also higher in that farm that gave concentrate twice or more (2.09+0.21 liter daily per cow) than those farms feed concentrate once daily (0.95+0.15 liter daily per cow). Incase of small dairy farming, the farms were facing a lot of problems such as scarcity of feeds and fodder, high price of concentrate and lack of technical knowledge. Although the dairy cow owners face problems, the study observed that there were potentials particularly for the small dairy farmers.

EFFECT OF IMPROVE FEEDING ON PRODUCTIVE AND REPRODUCTIVE PERFORMANCE OF CROSSBRED HEIFERS AND COWS SIDDIQUE, MD. SHAHRIOR Dairy cattle rearing is an inseparable and integrated part of the smallholder subsistence farming system. Dairy cattle production in Bangladesh is characterized by low productivity levels due to mainly genetic and nutritional constraints. It is a fundamental approach to provide good quality diets to dairy cattle for optimum production. Therefore the study was designed to compare the productive and reproductive performance of LocalxHolstein-Friesian (LxHF) and LocalxSahiwal (LxSh) crossbred heifers and cows under traditional feeding system and improved feeding system. A total of 100 crossbred heifers and cows (LxHF, 50 and LxSh, 50) were selected from three upazillas of Lalmonirhat District reared under improved feeding system or traditional feeding system. The productive performances like daily milk yield and lactation period and reproductive performances like age at first heat, services per conception, age at first calving, gestation length, post-partum heat period and calving interval parameters were studied by collecting data through a well prescribed questionnaire. The result revealed that among the productive parameters daily milk production were significantly (P<0.05) improved in the LxHF crossbred heifers and cows were managed under improved feeding system compared to the cows were managed under traditional feeding system. On the other hand, among the reproductive parameters, age at first heat, services per conception, post-partum heat period, calving intervals were also improved (P<0.05) in the crossbred heifers and cows were managed under improved feeding system than the traditional feeding system. Age at first heat, age at first calving and calving intervals in LxHF crossbred and services per conception and post-partum heat period in LxSh crossbred were slightly improved (but not significantly) by improved feeding system. Where daily milk production of LxSh crossbred cows and lactation period of LxHF crossbred and LxSh crossbred cows were slightly increased (P>0.05) by improve feeding. So, it is suggested that the productive and reproductive performance of crossbred heifers and cows may be improved by improved feeding system. In the socio-economic aspects of Bangladesh, it is crying need to improve the productive and reproductive performance of crossbred dairy cows. The present result revealed that the productive and reproductive performances of crossbred heifers and cows were higher under improved feeding system compared to the traditional feeding system. So it may be suggested that the farmers of Lalmunirhat District should provide improve feeding to their crossbred heifers and cows to achieve better performances.
