The study was designed to investigate the efficacy of Aloevera and Garlic extract in drinking water in order to evaluate the bird’s performance, carcass characteristics and economic utility on broiler rearing that includes production cost, profit per bird (PPB) and benefit cost ratio (BCR). The experimental birds were allocated randomly into 3 treatments and a control group with three replications having 8 broilers per replication. The AVG was mixed with drinking water at three concentration levels: 1% Aloevera gel of DW in DW (T 2 ), 1% Garlic of DW in DW (T 3 ), 0.5% Aloevera gel + 0.5% Garlic of DW in DW (T 4 ) and the group without AVG supplementation was control (T 0 and T 1 ). As per the result T 4 performed well according to the production performance. Results demonstrated that the average water intake in different groups were insignificant (P>0.05). A significant difference (P<0.05) was noted on body weight, feed consumption, body weight gain (BWG) in the birds treated with AVG. Additionally, Feed Conversion Ratio (FCR) had been improved. The better FCR was observed in combined AVG treated group, T 4 (1.31) than the other. A difference was figured on broilers survivability between the treatment groups and the control. Carcass percentage was significantly (P<0.05) higher in all treatment groups than control. Edible portion of birds was found significantly (P<0.05) higher in T 4 (67.00%±0.58) than T 2 (66.00%±0.58), T 3 (65.67%±0.33), T 1 (65.00%) and control T 0 (64.67%±0.67). The combination of aloevera and garlic was not cost effective due to the treatment cost. Where, the antibiotic positive and the antibiotic negative control were cost effective. However, negative control had been found with higher mortality than the other. It is reviewed that, though antibiotic promotes the growth, such type of practice reduces the natural improvement of gut environment as well as disease fighting capability, a reason behind reducing production in broiler industry. Therefore, the application of AVG will help naturally, in production without resistance. However, Aloevera & Garlic induced treatments (T 2 , T 3 , T 4 ) lead to less BCR and profit than controls (T 1 ). It is recommended that T 4 (0.5% Aloe+ 0.5% Garlic) can be used for safe broiler meat production rather than using antibiotics. , T 0 A Thesis Submitted to the Faculty of Animal Science & Veterinary Medicine, Sher-E-Bangla Agricultural University, Dhaka-1207, in Partial Fulfillment of the Requirements For the Degree of MASTER OF SCIENCE (MS) IN ANIMAL NUTRITION SEMESTER: JULY-DECEMBER/2019 2019-12-01T00:00:00Z http://localhost:8080/handle/123456789/3138 EFFECT OF SEASON ON REPRODUCTIVE PERFORMANCE OF BLACK BENGAL GOAT IN DINAJPUR DISTRICT AKHTER, MOST. SELINA This study was conducted at different places of Dinajpur district namely Kornai, Noshipur, Bangibachar hat, Vagobanpur from July/2017 to June/2018. Birth weight of kids were 0.94±0.02, 1.05±0.02 and 0.90±0.02 kg respectively in summer, rainy and winter season of Black Bengal goat. The birth weight of Black Bengal kids at 1st, 2nd, 3rd and 4th parity were 0.95±0.02, 0.97±0.01, 0.98±0.02, 0.96±0.03 kg respectively. There is no significant effect of parity on birth weight of Black Bengal kids. Average gestation length of Black Bengal goat at summer, rainy and winter season were 142.9±0.52, 143.2±0.54 and 145.6±0.48 days respectively. The average litter size of Black Bengal goat at summer, rainy and winter season were 2.09±0.10, 2.01±0.10 and 2.07±0.09 respectively. The average litter size of Black Bengal goat at 1st, 2nd, 3rd and 4th parity was 1.53±0.09, 1.83±0.08, 1.97±0.09 and 2.17±0.15 respectively. There is no significant effect of season on litter size of Black Bengal goat. But there is highly significant (p<0.01) effect of parity on litter size of Black Bengal goat. Average age at puberty of Back Bengal goat at summer, rainy and winter season were 185.45±3.03, 182.72±3.10 and 183.95±2.76 days respectively. There is no significant effect of season on age at puberty of Black Bengal goat. The average age at first kidding of Black Bengal goat at summer, rainy and winter season were 369.82±1.76, 371.92±1.80 and 366.02±1.60 days respectively. There is no significant differences between season and parity on kid mortality rate but there is a significant (p<0.05) effect of season on birth weight of kid, gestation length, age at first kidding and weight at first kidding of Black Bengal goat. The average weight of first kidding of Black Bengal goat at summer, rainy and winter season were 9.34±0.16, 9.33±0.16 and 7.79±0.14 kg respectively. There is no significant effect of season on lactation length of Black Bengal goat. The average lactation length of Black Bengal goat at summer, rainy and winter season were 72.8±0.54, 73.2±0.55 and 73.07±0.49 days respectively. Average kidding interval of Black Bengal goat at summer, rainy and winter season were 186.97±0.82, 184.3±0.84 and 190.48±0.75 days respectively. There is a highly significant (p<0.01) effect of kidding interval on season but having a significant (p<0.05) effect of kidding interval on parity. There is no significant effect of season and parity on kid mortality rate of Black Bengal goat. The average kid mortality rate of Black Bengal goat at summer, rainy and winter season were 16.66±6.39, 18.75±6.54 and 24.79±5.82 % respectively. The average kid mortality rate at 1st, 2nd, 3rd and 4th parity was 17.36±5.75, 20.60±5.40, and 20.64±6.14 and 14.09±9.31 %. From this experiment it can be concluded that better reproductive performance found in rainy season because the birth weight of kid, age at puberty, lactation length, kidding interval was better than other season. The reproductive performance was excellent in fourth parity because litter size, kidding interval, kid mortality rate were better than other parity.

The study was carried out by a total of 150 day-old Cobb 500 broiler chicks were reared in Sher-e-Bangla Agricultural University Poultry Farm, Dhaka. This study aimed at comparing the performance of commercial broiler submitted to lighting using different LED colors or conventional incandescent lamps. This study maintain standard lighting program and were fed balance diet. The overall growth performance of broiler in red LED, green LED and 40W incandescent light were almost same. Body weight was comparatively better (P<0.01) among studies green light sources. Feed conversion ratio (FCR) and feed consumption was almost similar in red LED, green LED and 40W incandescent light. Uniformity (%) was significantly different (P<0.01) among studies, with the best results obtained with red LED light sources. It was concluded that the replacement of incandescent light bulbs by red and green LEDs does not cause any negative effect on the growth performance of commercial broiler. Therefore, switching to red and green LEDs may be can result in overall increased revenue for farmer because of the lower energy costs.

One-day old of Cobb-500 broiler chicks (n=150) were randomly allocated into five treatments. Each dietary treatment consisted of 3 replicates having 10 broilers in each of the replication. The dietary treatment contained no live yeast and oligosaccharide considered as control (T 0 ) and the other four treatments were T (2g yeast and 0.5g oligosaccharide/kg feed), T 1 (1g yeast and 0.5g oligosaccharide/kg feed), T (1g yeast and 1g oligosaccharide/kg feed) and T 4 3 (2g yeast and 1g oligosaccharide/kg feed). During the experimental periods of 4 weeks, feed intake, body weight gain, feed conversion ratio (FCR), survivability, flock uniformity values were calculated. Growth performance parameters were significantly (P<0.05) affected by experimental diets. Birds fed 1g yeast and 1g oligosaccharide/kg feed gained superior body weights (1765.90±4.89g) compared to control (l469.43±18.29g), and other dietary treatment. The mean body weight gains (g) at the 1 , 2 nd , 3 rd and 4 th week of different treatment groups were significantly higher (P<0.05) than control group. The feed intake of T (1g yeast and 1g oligosaccharide/kg feed) group was lower (2307.30±3.66g) compared to control (2421.07±25.99g). The groups fed diets containing 1g yeast and 1g oligosaccharide had lower FCR (1.33±0.00) compared to control (1.69±0.03). The inclusion of different dietary treatments had no significant (P>0.05) effects on survivability and flock uniformity. It is concluded that live yeast and oligosaccharide can be included in broiler diet at the rate of 1g yeast and 1g oligosaccharide/kg feed for better performance and higher economical return. 3 st 2 A Thesis Submitted to the Faculty of Animal Science & Veterinary Medicine, Sher-e-Bangla Agricultural University, Dhaka-1207, in Partial Fulfillment of the Requirements For the Degree of MASTER OF SCIENCE (MS) IN ANIMAL NUTRITION SEMESTER: JULY-DECEMBER/ 2019 2019-12-01T00:00:00Z
