GROWTH PERFORMANCE OF BROILER FED DIET CONTAINING DE OILED RICE BRAN SUPPLEMENTED WITH PROTEASE AND HALQUINOL ISLAM, MD TAJUL The research was conducted to determine the effects of de oiled rice bran, protease enzyme and halquinol in feed on the performance of broiler chicken. A total of 816 day-old IR broiler chicks were allocated randomly to four treatment groups with six replications having 34 birds per replication. All the birds were assigned to four treatments such as T 0 (Control), T 1 (Basal feed with 50 kg DORB and 500g Halquinol per metric ton of feed), T 2 (Basal feed with 50 kg DORB and 200g Enzyme Protease per metric ton of feed) and T 3 (Basal feed with 50 kg DORB, 200g Enzyme Protease and 500g Halquinol per metric ton of feed). Result demonstrated that the highest body weight (g) was found in T 3 (1817.75 g) and lowest result was found in T 2 (1780.58 g) group. But, higher body weight was found in T 3 group than control group T 0 and that was statistically significant (P<0.05). The highest body weight gain was found in T 3 IX (1776.75 g) and lowest result was found in T 0 group (1744 g) and that was statistically no significant (P>0.05) difference. The highest result was found in T 2 (2379.39 g) and lowest result was found in T 3 group (2318.46 g) and that was statistically significant (P<0.05). The best FCR was found in T 3 (1.47) and worse FCR was found in T 1 and T 2 group (1.56) but better FCR was found in T 3 (1.47) than control group T 0 (1.54) and that was not statistically significant (P>0.05). Survivability rate (%) was higher in treated group T 3 than control group T 0 . There was significant difference (P<0.05) in survivability rate (%). BCR was non significantly higher (P>0.05) in treatment group T 3 (1.49) than control group T 0 (1.41). The above research was found that body weight (g), body weight gain (g), survivability rate (%) and BCR were better result in T 3 group than other groups including control group T 0 (Basal feed). FCR was better in T 3 group than other groups including control group T 0 (Basal feed). Better result was found in T 3 (Basal feed with 50 kg DORB, 200g Enzyme Protease and 500g Halquinol per metric ton of feed) group than control group.

USE OF COMBINATION OF SELECTED BACTERIOPHAGES IN BROILER RATION: A SUSTAINABLE ALTERNATIVE TO ANTIBIOTIC GROWTH PROMOTERS YEASMIN, FATIMA Antibiotic growth promoter alternatives are urgently needed in the poultry industry to maintain or improve poultry health and performance. Bacteriophage (BP) therapy mainly utilizes lytic phage to kill their respective bacterial hosts and exhibit no activity against animal and plant cells. They can be considered novel alternative solution to combating the emergence of antibiotic resistance in poultry. A total of 600-day-old mix broiler chicks (Hubbard Classic Efficiency Plus) with the initial body weight of 41.9±1.0 g were reared for 35-days experimental period. Birds were randomly allotted into 1 of 5 treatments according to a Completely Randomized Design (CRD). Dietary treatments consist T 0 Control (no antibiotics and no BP), T 1 xiv (0.5 gm BP/kg of feed), T 2 (0.75 gm BP/kg of feed), T 3 (1.0 gm BP/kg of feed) and T 4 antibiotic control group (0.055 g antibiotic BMD/kg feed) (bacitracin methylene disalicylate). The group T 1 (P <0.05) showed higher body weight (2251.58± 15.10 g) compared to T 0 (2027.78± 6.11 g) and T 4 (2093.93± 20.28 g). Best FCR result was found in T 1 (P <0.05) (0.5g BP/kg) group (1.49) compared to the T 4 antibiotic treated group (1.54) and T 0 Control group (1.58). The group T 3 (P <0.05) showed higher feed consumption compared to T 0 and T 4 . Escherichia coli concentration in excreta is higher (6.84 log10CFU/g) in T 0 differ significantly (P<0.05) with other groups. Salmonella concentration is higher (4.28 log10 CFU/g) in T 0 and differ significantly (P<0.05) from other groups however not significantly different (P = 0766.) from T 4. The weight of the spleen in the control group T 0 is the highest and is differ significantly (P<0.05) with other groups. Similarly, the bursa of fabricus' weight is the highest in T 0 group and differs significantly (P<0.05) with other groups. Among the three-bacteriophage dietary treatment group T 1 showed better body weights and FCR than group T 2 and T 3 . In conclusion, dietary supplementation of 0.5 g/kg BP reduced FCR and increased body weight with inhibiting of pathogens. Therefore, the research recommended inclusion of 0.5 g BP/kg of feed as an alternative to antibiotic growth promoters in broiler diets.

EFFECT OF CINNAMON AND GARLIC ON GROWTH PERFORMANCE AND CARCASS CHARACTERISTICS OF BROILER SUMI, FARHANA YESMIN The aim of the study is to evaluate the effect of feeding cinnamon and garlic on growth performance and carcass characteristics of broiler. The experiment was conducted by applying different levels of cinnamon and garlic with commercial broiler feed. A total of 180 one day-old of Lohmann Meat (Indian River) broiler chicks were purchased from Kazi farms hatchery, Gazipur, Dhaka. In the experiment broilers were randomly allocated into four treatments and a control group. Each dietary treatment consisted of 3 replications having 12 broilers in each of the replication. The dietary treatment consisted for 4 weeks and the treatment of various groups consisted as control (T 0 ) and the other four treatments were T 1 (basal feed + antibiotics), T 2 (basal feed + 0.2% cinnamon), T 3 (basal feed + 0.2% garlic) and T 4 (basal feed+ 0.2% cinnamon + 0.2 garlic). During the experimental periods of 4 weeks feed intake, body weight gain, feed conversion ratio (FCR), dressing percentage were calculated. Birds fed 0.2% cinnamon and 0.2% garlic (T 4 ) gained superior body weights (1958.33 a ±21.05) compared to any other group T 0 (1912.33 ab ±16.49), T 3 (1896.33 ab ±17.40), T 2 (1886 ab ±21.65) and group T 1 (1866 b ±29.01). The average body weight gains on T 4 group at the 1 st weeks were significantly higher (P<0.05) than other treatment groups. The groups fed diets containing 0.2% cinnamon and 0.2% garlic feed (T 4 ) had lower (best) FCR (1.30±0.01) compared to group T 3 basal feed with 0.2% garlic (1.32±0.02), group T 2 basal feed with 0.2% cinnamon (1.33±0.01), group T 1 basal feed with antibiotic (1.33±0.02) and group T 0 basal feed (1.34±0.01). However, evaluation of dressing percentage on slaughtered representative birds revealed that group T 4 (57.60±0.73) had significantly higher dressing percentage than group T 1 (57.56±0.62), group T 0 (57.27±1.27), group T 2 (56.92±0.64) and lower in group T 3 (55.77±0.44). It is concluded that the use of 0.2% cinnamon and 0.2% garlic in broiler diet separately or combined resulted in improved growth performance and carcass yields in broiler chicken.

EVALUATION OF PRODUCTIVE AND REPRODUCTIVE PERFORMANCE OF NON-DESCRIPT BUFFALOES OF BHOLA DISTRICT IN BANGLADESH HEERA, ROKAIYA SULTANA The aim of the study was designed to Evaluate the Productive and Reproductive Performance of Non-Descript Buffaloes of Bhola District in Bangladesh. Data were collected through interview of randomly selected 349 members of Bhola districts who were involved in buffalo farming. The investigation revealed that majority of the buffalo farmers were poor (46.47%) and non-poor (45.07%), the education level of the farmers were below primary (70.48%), and up to primary (31.48%), age of the farmers were over 25 years old (72.27%), and among them about 96.36% farmers were male. The family members of the buffalo farmers ware average 5.28. The mortality rate of buffalo calves and buffalo, were 17.08% and 8.75% respectively. The average lactation period was 5.77±0.26 months, gestation period 285±0.70 days average milk production per day was 1.56±0.25 liter and total milk production in lactation period was 268.08±6.34 liters. The reproductive parameters like age at first heat 37.2±0.25 months, age at first pregnancy 38.4±0.26 months, number of services per conception 1.77±0.26 number, duration between estrus and insemination 10.09±0.70 hours, post-partum heat period 106.20±0.36 days, dry period 167.8±0.67 days, calving interval 660.8±0.97 days, Pregnancy rate 28.03±.02 % and age at puberty 455.33±.27 days respectively. All (100%) of the farmers practice natural insemination technique, where 63.1% farmers have their own bull for breeding. No farmer use record keeping system in the farm. There is a believe that buffalo meat is not good for health that the reason consumer refuse to take buffalo. There is no available market for buffalo meat. This study would help the policy makers to take necessary strategies to improve the socio-economic status of buffalo farmers in this region of Bangladesh.
