To observe the productive performance of one batch of commercial broiler quail from hatching upto marketing age (0-6 wks) under litter floor rearing system, an observational study was conducted for a period of 42 days from July 10 to August 20,2009. The works were done with 400 broiler birds separately reared in two sheds.The chicks were hatched in the own hatchery of farm. Temperature and ventilation were properly maintained during brooding period (0-2 wks). The feeding system was ad-libitum basis. The birds were reared for 6 wks (marketing age) and were sold when the weight of 110-120gm was aquired. The result of the study showed that the feed intake of birds were 2.45, 7.5, 10.4, 17, 19 & 22g in 1st, 2nd, 3rd, 4th, 5th and 6th weeks respectively. The average weight gain was 120gm at 6 wks with an average feed conversion ratio of 4.56:1. Mortality rate was 4.02%.Item A STUDY ON COLLECTION AND EVALUATION OF DIFFERENT UNCONVENTIONAL TREE LEAVES AVAILABLE IN CHITTAGONG AREA.(Chattogram Veterinary & Animal Sciences University, KHULSHI, CHITTAGONG-4225., 2013-02) Kumar Roy., S.M .PrabirThe present study was conducted to evaluate the nutritive value of krisnachura, ipil-ipil, Neem, kanchan flower, Raintree, Christhmas tree, Mehogony, Koroi, collected from different areas of Chittagong region. A total 32 samples were analyzed to evaluate the percentage of dry matter (DM), ash, crude protein (CP), crude fibre (CF) ether extract (EE) Nitrogen free extract(NFE),Metabolic energy(ME). The DM content is higher incase of Neem (68%) lower in case of kanchan flower (52%). The ash content is higher incase of Neem(11%) lower in case of kori(4.11%). The ether extract content is higher incase of Koroi (13.4%) lower in case of Raintree(2%). The crude protein content is higher incase of Ipil-ipil (23%), lower in case of Raintree (11%). The crude fiber content is higher incase of Christmass tree (43%), lower in case of Mehogony (25%) .From this study it is observed that this fodder contain proximate value which can satisfy the nutritive value in ruminants diet and it can be recommended that these unconventional tree leaves may be used as animal feed as alternative to other feed stuffs of animal. So, the different tree leaves may be used as a supplement with value in addition to animal ration formulation.Item A STUDY ON EFFECT OF GARLIC POWDER ON PERFORMANCE OF BROILER(Chattogram Veterinary and Animal Sciences University Chattogram-4225, Bangladesh, 2017-12) Sultana, TahminaGarlic powder contains several biologically active substances with prebiotic activity. The aim of this experiment was to evaluate the influence of dietary supplementation of garlic powder on performance,and serum lipid profile parameters of broiler chickens. A total of 108 day old chicks (DOC’s) were randomly distributed in three groups in a completely randomized design (CRD) having three replications per group. Those birds were treated either without garlic powder (GP) (T0/control) or with 1% GP (T1) and 1.5% GP (T2) in their regular basal diet and reared for four weeks. Data on performance parameters (feed intake, live weight, feed conversion (FC), weight gain etc.) were measured on weekly basis and data on serum lipid profile parameters (i.e. Cholesterol, Triglycerides, LDL-cholesterol and HDL-cholesterol levels), were recorded at the end of the experimental period. Results revealed that there was significant (P<0.01) increase in feed consumption by birds at 1st, 3rd and 4th weeks of age of broilers with supplementation of garlic powder. Initially no significant (P>0.05) difference was observed in body weight of broilers. Then, highly significant (P<0.01) differences were observed in body weight of birds throughout the whole experimental period with highest weight in 1.5% GP supplemented group (T2). The second highest value was observed in T1 group (1% GP). FC was significantly improved in 1st (P<0.05), 2nd, 3rd, and 4th weeks of age of birds (P<0.01) with better FC in groups supplemented with GP. Cumulative FC was also significantly (P<0.01) improved upto 3rd and 4th weeks of age of birds both in T1 and T2 groups compared to control group. The Cholesterol, triglyceride and LDL-cholesterol levels were significantly (P<0.01) decreased in GP supplemented groups (T1 and T2). Significantly higher HDL-cholesterol level (P<0.01) was found in T1 and T2 groups than T0 group. Almost all the performance parameters were best in 1.5% GP treatment group than all the groups. This may be recommended for broilers.Item A STUDY ON NUTRITIVE VALUE OF SAWDUST(Chattogram Veterinary and Animal Sciences University Khulshi, Chattogram-4225, Bangladesh, 2012-05) Rahman, Md. JahidurThe present study was undertaken to observe the chemical composition of different types of sawdust available in the metropolitan areas of Chittagong, Bangladesh. Twenty different types of sawdust of difeerent plants were collected from study areas. Chemical analyses of the samples were carried out in triplicate for moisture, dry matter (DM), crude protein (CP), crude fiber (CF), nitrogen free extracts (NFE), ether extracts (EE) and total ash in the animal nutrition laboratory, Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh. Results indicated that, there were no marked variations (P0.05) in the moisture, dry matter and total ash contents of the samples. However, crude protein, crude fiber, nitrogen free extracts and ether extracts content significantly differed (P0.01) from one sample to another. Moisture content varied from 2.6 to 8.4 g/100g, dry matter content varied from 91.40 to 97.40 g/100g, crude protein content varied from 1.8 to 43.5 g/100g, crude fiber content varied from 41 to 74 g/100g, ether extract content varied from 1.0 to 3 g/100g, nitrogen free extracts content varied from 12.8 to 60.24 g/100g and total ash content varied from 0.67 to 2.6 It could therefore, be inferred that, sawdust currently available in the local market are widely variable in terms of their quality.Item A Cohort Study on the Health and Reproductive Success of Red Kangaroos (Macropus rufus) in Chattogram Zoo: Seasonal, Behavioral, and Antimicrobial Resistance Insights(Faculty of Veterinary Medicine, Chattogram Veterinary and Animal Sciences University, Khulshi, Chattogram-4225, Bangladesh, 2024-10) Mya, UayeItem A comparative study between proximate analysis of Layer poultry feed of Namakkal and Chittagong(A Production Report Submitted in partial satisfaction of the requirements for the degree of DOCTOR OF VETERINARY MEDICINE Faculty of Veterinary Medicine. CHITTAGONG VETERINARY AND ANIMAL SCIENCES UNIVERSITY, KHULSHI , CHITTAGONG, 2015-12) Ullah, AhmedABSTRACT The study was carried out to acquire a comparative proximate analytical picture between layer feeds of Mohanur raj poultry farm in Namakkal and Kazi poultry farm in Bangladesh which are formulated in their farm on the basis of the requirement birds (hen). As the quality of feed is one of the main determinant factors in successful poultry farming, an attempt was made to compare the quality of both Namakkal layer feed,India and Kazi layer layer feeds, Chittagong. The feed was formulated on Layer-layer basis. The proximate analysis of these feeds showed the following composition such as moisture, crude protein (CP), crude fibre (CF), ether extracts (EE), ash and metabolizable energy (ME). The proximate analytical nutrient concentrates were moisture 10.4% and 10.1%, %CP 17.85% and 19.00%, %EE 2.4% and 4.3%, %CF 6.1% and 4.00%, % ash 6.5% and 6.3% finally ME 2650.72 Kcal/kg and 2800 Kcal/kg respectively Namakkal farm feed and Chittagong farm feed. There was significant difference observed in these feed samples with regards to some nutrient concentration. The age of the birds of two farms was also same (55-60 wkks). From this experipent, it was observed that the quality of feed used in Mohanur raj poultry farm (Namakkal) is better than Kazi poultry farm (Chittagong) and the nutrients are also closed to the standard. This experimental study may be helpful for Bangladeshi farmers and poultry nutritionists to compare between for mixed layer of Bangladesh with Indian (Namakkal) hand mixed layer feed.Item A COMPARATIVE STUDY OF DIFFERENT METHODS OF MEAT PRESERVATION(Chittagong Veterinary & Animal Sciences University, Khulshi- Chittagong-4225, 2013-02) Islam, Md. ManirulThe study was conducted to observe comparative assessment of meat preservation by using different method. The experiment was divided into three treatment groups having two replications. Three samples were collected from locally available markets. Where sample 1 was persevered by freezing method, sample 2 by pickling with vinegar and sample 3 by salting with common salt. The initial pH of the meat samples (S1,S2, S3) were 5.84, 6.33 and 5.90 respectively. The initial moisture percentage of these (3) samples were 77.43, 70.25 and 76.10, respectively. And the total viable count of bacteria was(1.8x106/CFU) in sample1, 2.3x106/CFU) in sample3 which were negligible and in sample2 the microbial load was 14x106CFU/gm. After one month of preservation, the second reading was taken from the same samples. There are some changes observed in pH, moisture, texture, color and TVC. It is revealed that the preserving of meat by salting is significantly better than other two methods. So, it may be concluded that the meat preserving by salting more safety, more reliable and more economic for human consumption.Item A COMPARATIVE STUDY OF THE MANAGEMENT SYSTEM OF COBB 500 BROILER PARENT STOCK IN M.

ShahadatA study was carried out in three renowned breeder farms in Chittagong district of Bangladesh. The objectives of the study were to compare the management practices and production performances of parent breeder stock of about 29800 Cobb 500 strain reared in those farms (farm A, B and C). The duration of the study was August 10 to August 30’ 2016 which was done on 18-50 weeks of ages of birds. Relevant information’s related to management of birds (i.e. housing feeding, lighting, vaccination schedule, temperature management, bio-security etc.) were recorded from register book of farms and compared with the standard. Data related to production performance (i.e. feed intake by male and females, live weight, egg production etc.) were also recorded and analyzed. It was revealed that farm A, B and C maintained standard management systems. There was no significant difference (P>0.05) in feed intake by female breeders of three farms though it differed significantly (P<0.05) in males and was higher in farm B and C in comparison with farm A. However, no significant differences (P>0.05) were observed among body weight of male and female birds of farm A, B and C. Egg production was insignificantly (P>0.05) higher in farm B compared to farm A and B. Peak egg production in farm A was observed at 30th weeks (90%), farm B at 31- 42th weeks (95%) and farm C at 32th weeks (91%). From the study it was evident that there were fewer differences in existing management systems of farm A, B and C. Cob 500 performed well in that system. Insignificant amount of differences were observed among the production data of three farms almost in all parameters. It was also noted that production performance in a breeder farm depends mainly on the management practices and there is a negative correlation between the feed intake and egg production of birds.Item A Comparative Study ofHerbal Products on Growth Performance, Carcass Quality & Serum Biochemical Parameter of Broiler(A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Animal and Poultry Nutrition Department of Animal Science and Nutrition Faculty of Veterinary Medicine Chittagong Veterinary and Animal Sciences University, Chittagong-4225, Bangladesh, 2018-06) Das, DR.

Age at first calving, Days open, gestation period, Calving interval and number of services per conception were considered as reproductive parameters whereas average daily milk yield and lactation length considered as productive parameters. In CCBDF, average age at first calving of Local x Friesian cows was 47.86 13.69 months whereas in SDF it was 38.29 5.21 months. The average days open in CCBDF and SDF were 301 114 days and 149 41 days respectively. Average gestation period in CCBDF was 277.52 7.72 days and in SDF 279.51 7.82 days. Average calving interval in CCBDF and SDF were 614 146 days and 431 62 days respectively. Average No. of services per conception in CCBDF was 1.70 0.62 Whereas in SDF 2.13 0.89. Average daily milk yield per cow in CCBDF 4.48 0.86 Ltr. whereas in SDF it was 8.62 2.88 Ltr. Average lactation length in CCBDF and SDF Were 319.53 96.09 days and 303.17 26.09 days respectively. So, it is evident that, Local x Friesian herd of super Dairy Farm performs better than that of CCBDF, Savar.Item A COMPARATIVE STUDY ON THE PRODUCTIVE PERFORMANCE OF BROILER USING MAIZE AND PALM OIL(Chattogram Veterinary and Animal Sciences University Khulshi, Chattogram-4225, Bangladesh, 2012-05) Rahman Sarker, HafizurThe study was conducted to observe the productive performance of broiler replacing vegetable oil by maize in different level. The experiment was designed by two treatment groups and each treatment having three replications consist of 25 birds in each replication. Two rations were formulated using locally available ingredients where T0 was formulated with maize (without oils) and T1 with palm oil (oil group). The body weight of broiler feeding maize at 1st, 2nd, 3rd, 4th and 5th weeks are 117.67 g, 271 g, 631.17 g, 1055.28 g and 1572.81 g while feeding palm oil these are 120.43, 267.84, 641.00, 1072.99 and 1587.69 which differ significantly (P<0.01) with former to later one. The weekly average feed intake of broiler with maize from 1st week of to 5th week are 79.46 g, 221.51 g, 553.04 g, 750.20 g and 1079.00 g differed significantly (P<0.01) with feeding palm oil which are 81.58 g, 222.56 g, 635.86 g, 750.59 g and 1094.67 g. Similarly the FCR of feeding maize birds are 1.10, 1.13, 1.43, 1.45 and 1.76 while birds with feeding palm oil are 1.05, 1.09, 1.37, 1.37 and 1.66 which also significantly (P<0.01) varied. Average mortality rate was 1% for T0, T1 group respectively. It is revealed that the performance of broiler feeding palm oil is significantly better than maize feeding birds. So, it may be concluded that the commercial rearing of broiler feeding palm oil is more profitable than without oil.Item A COMPERATIVE STUDY ON LAYER FEEDS OF AFAQAL AND CP(A Production Report Submitted in partial satisfaction of the requirements for the degree of DOCTOR OF VETERINARY MEDICINE Faculty of Veterinary Medicine CHITTAGONG VETERINARY AND ANIMAL SCIENCES UNIVERSITY, KHULSHI, CHITTAGONG., 2015-12) Hossion, Md. ZakariaFeed represents the major cost of poultry production, constituting up to 70 percent of the total cost. Of total feed cost, about 95 percent is used to meet energy and protein requirements, about 3 to 4 percent for major mineral, trace mineral and vitamin requirements, and 1 to 2 percent for various feed additives. Poultry diets are formulated from a mixture of ingredients, including cereal grains, cereal by-products, fats, plant protein sources, animal byproducts, vitamin and mineral supplements, crystalline amino acids and feed additives. These are assembled on a least-cost basis, taking into consideration their nutrient contents as well as their unit prices. As the quality of feed is one of the main determinant factors in successful poultry farming; an attempt was made to compare the quality of commercial layer feeds to identify the different proximate component. For this two feed samples were collected from two specific places. CP feed sample was collected from a nearby shop of Chittagong metropolitan area and the other feed sample was collected from Animal Feed Analytical and Quality assurance Laboratory (AFAQAL) of VC&RI, Namakkal, Tamilnadu, India. The CP feed are commercially available in Bangladesh. Proximate analysis was done to see the nutritive values. Those values were then compared with the standard value. Finally both data of proximate analysis & economic one were compiled by using Microsoft Excel 2007 (Chi-square test by using SPSS 16.0). The proximate analysis of two feeds are showed the following ranges of nutrient compositions DM (88-90)%, Moisture (10.5-11.5)%, CP (16-18)%, CF (5-6)%, EE (3-4)%, Ash (6-6.6)%, NFE (53.2-55.05)%, ME (2666-2685) Kcal/kg. From this experiment, it was observed that the nutritive value of AFAQAL feed is comparatively better than CP feed as the nutritive values are very close to the specified values.Item A CROSS SECTIONAL STUDY OF LAYER DISEASES IN FENI DISTRICT(Chattogram Veterinary & Animal |Sciences University, 2010-04) Hossain, Md. BelalThe pattern of occurrences of poultry diseases in commercial layer farms was studied based on post mortem and other examination of 135 cases either dead or live birds during the period of 01.06.2009 to 31.12.2009 in the district of Feni one of the fastest growing poultry belt in Bangladesh. In the study highest number of cases of diseases found Salmonellosis(22.96%),Fowlcholera(15.56%),Colibacillosis(9.62%),Necroticenteritis(08.89%),IBD(08.89%),ND(08.15%),Coccidiosis(9.62%),Lymphoidleucosis(2.23%),EggPeritonitis(5.19%),Cannibalism(2.96%),Vitamin E deficiency(1.48%),and heat stroke(1.48%).it was very obvious from conducted study that all age groups of birds are susceptible to various diseases but the laying period is most vulnerable, and most mortality of chickens are caused by Salmonellosis, Colibacillosis, Fowl cholera, Infectious bursal disease, Newcastle disease and Necrotic enteritis which demand immediate attention for prevention and control for assuring the most progressive egg laying industry
