At the age of 35 days, average body weight and feed intake were 102.15 and 320.71 g/quail for cage rearing system and 78.41 and 241.89g/quail for floor rearing system respectively. FCR were 3.89 and 4.10 for cage rearing system and floor rearing system respectively, at the age of 35 days. Body weight, feed intake and FCR were significantly different between cage and floor rearing system. At the age of 21 and 35 days survivability were 72.72 and 72.72 % for cage rearing system and 63.63 and 60.60 % for floor rearing system respectively. There was higher survivability in cage than floor rearing system in 35 days. In case of meat yield characteristics, average weight of breast, thigh, wing, drum stick were 20.92, 7.37, 5.42 and 5.72 g for cage and 20.84, 7.35, 5.39 and 5.63 g for floor respectively. There were no significant difference among average weight of breast, thigh and drum stick between two rearing system and in case of sex. But in case of average wing weight there were significant difference among sex. It may be concluded from this study that cage reared quails showed better performance compared to littered floor rearing system in Sylhet district. 2015-06-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/314 STUDY ON RICE HUSK INCUBATOR OF DUCKLINGS PRODUCTION IN HAOR AREAS OF SYLHET Makaremuzzaman, Md. The present study was carried out to know the hatchability percentage and profitability of ducklings production through rice husk incubator among nine farmers of different groups ( small, medium and large) of farmers in Dirai, Doarabajar, Jamalgonj and Sunamgonj Sadar upazilla of Sunamgonj District during 1 February 2014 ( 19 Magh 1420) to 31 May 2014 (17 Joistho 1421) those are traditionally produce Day Old Ducklings (DODs) through rice husk incubator. The large, medium, and small farmer groups having the capacity to produce (> 3000 DODs), (20013000 DODs), and (1500-2000 DODs) per month respectively. Different five hatches were counted for each farmer. It was observed that average hatchability percentage among small, medium, and large groups was (66.20±2.49), (67.59±2.55), and (65.83±2.97) respectively. Average fertility percentage among small, medium, and large groups was (86.85± 1.38), (83.7±2.06), and (85±1.10) respectively. Average embryonic death percentage among small, medium and large groups was (24±3.12), (19.54±1.89), and (22.63±2.63), respectively and average profitability percentage among small, medium and large groups was (68.64±18.75), (71.5±11.3), and (29.66±12.6) respectively. There were no effect on fertility and hatchability among the farmer groups. Profitability was significantly higher in small and medium groups than large farmer group. 2015-06-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/313 EFFECT OF FEED SUPPLEMENTATION ON GROWTH PERFORMANCE OF SONALI CHICKEN IN HAOR AREAS OF SYLHET KHAN, JAMAL The research work was carried out on performance of sonali chicken through feed supplementation under scavenging condition at Haluagram village in Sunamganj district of Sylhet, Bangladesh. Hundred sonali hens (♂Rhode Island Red x ♀ Fayoumi) were distributed among 20 farmers at 15 weeks of age. Four different treatments were given in four different level of feed supplementation of rice. In each treatment consist of five farmers. Control (T0) was no supplementary feed, treatment 1 (T1) was 30 g supplementary feed, treatment 2 (T2) was 60 g supplementary feed, treatment 3 (T3) was 100 g supplementary feed with scavenging. Body weight and weight gain were significantly higher in T3 than the others. Similarly total body weight gain was significantly (P<0.05) higher in T3 treatments and lower in T0. Again, Significant differences (P<0.05) were found in body weight at 34 weeks. In laying period body weight was significantly higher in T3 than the other treatments and lowest in T1. In case of feed conversion ratio was no significant differences among the different treatments. The egg production was no significant differences among the different treatments. Though the egg production of control group was also lower. The egg weight was significantly higher in T3 than other treatments and the lowest value in T0. But similar egg weights were found between T1 and T3. High mortality percentage was found in T0 but lower in T1 during growing period. But similar mortality percentage were T2 and T3. During study period the laying was higher mortality percentage in T2 and lower was T1 and T3. The farmers were more benefited by the 30g supplementation compare to the others. Present results also indicate that at least 30 g of available feed supplementation needed for the scavenging crossbred birds for viable egg production, good feed conversion ratio and more profitable, because the scavenging feed is also dependent on available feed resources around the farmer’s house of hoar areas. 2015-06-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/240 NUTRIENT AVAILABILITY AND BODY COMPOSITION OF ADULT GIRIBAZ PIGEON (Columba livia) AND MEAT YIELD CHARACTERISTICS OF THEIR SQUAB HASAN, MD. KAMRUL Three experiments were conducted to evaluate nutrient availability, body composition of semi scavenging Giribaz pigeon and meat yield of their squab. The average DM, CP, CF, EE, ash, NFE, Ca and Av. P in crop and gizzard contents of male and female pigeon were 716.75, 108.50, 50.55, 15.90, 49.60, 574.25, 0.54 and 0.22 g/kg, respectively. The ME contents was 14.20 MJ/kg DM. The average live weight was 297.30g for male pigeon and 267.70g for female pigeon. Dressing percentage, total meat, breast meat, head and gizzard were 62.60, 34.52, 23.63, 3.09 and 1.91% for male pigeon and 56.80, 28.22, 19.45, 4.24 and 2.63% for female pigeon respectively. Live weight, dressing percentage, total meat and breast meat were (11.06, 5.80, 6.30 and 4.18%) higher (P<0.01) in males than females. While, females had heavier (P<0.01) head and gizzard (1.15 and 0.72 %) than males. Total meat, breast meat and wing meat were increased (P<0.01) with advancement of age of squab. Proportionate bone weight had no relation (P>0.05) with age. On the other hand, dressing percentage, total meat and breast meat were increased (P<0.01) with the increasing live weight. Weight of drumstick meat and total bone (neck weight+ wing bone+ vertebral column weight+ thigh bone + drumstick bone) did not maintain any relation (P<0.05) with live weight. It is concluded that feeds in crop and gizzard of pigeon were low in CP, EE, NFE, Ash, Ca and Av. P but higher in CF and ME. Live weight had pronounced effects on dressing percentage, total meat and breast meat in both adult and squab pigeons. Supplemental diet like CP, EE, NFE, Ash, Ca and Av. P were rich, whereas low in CF that could increase the production of semi scavenging pigeon. Nutrient availability and body composition between male and female pigeon is apparently negligible difference. 2014-12-01T00:00:00Z
