There are two major sources of chicken meat those are indigenous (native) chicken and commercial hybrid genotypes (broiler chicken). Among the meat, chicken has been considered as the cheapest and available to the consumers regarding to its price and quality. Meat from native chickens are preferred widely by consumers, because of their good pigmentation, better taste, leanness and their suitability for special dishes. The Japanese native chicken, Niigata Jidori, is available in the Niigata prefecture of Japan. Niigata Jidoriis bred from Plymouth Rock and the F1 hybrid of Tomaru and Nagoya, like HinaiJidori in Hinai area of North Akita prefecture of Japan. Hinaidori is one of the famous Japanese memorial native chickens. Since eating memorial native chickens in Japan is prohibited, F1 of Hinaidori and Rhode Island Red called HinaiJidori, is consumed instead. The meat of HinaiJidori is palatable and delicious in local dishes, like Kiritampo. Fujimura et al., (1991) have shown that the meat of HinaiJidori is tastier than that of broiler chickens. Similarly, the meat of Niigata Jidori is also tastier than broiler chicken meat. Market price of Niigata Jidori is higher than that of broiler owing to its good taste. Bangladesh consumer demands for native chickens are increasing because of their good pigmentation, better taste, leanness and their suitability for special dishes. Due to higher demand day by day, this indigenous chicken is being produced under intensive or semiintensive system of production on fully commercial diets. However, there are limited reports available on meat yield and quality attributes of native chicken feed on commercial diets of varying ingredients and nutrient composition. Most of the previous research has been focused on corn based diet with different rearing system and growing performance of broiler and native chicken. Still there is a lack of research on the production potential of Japanese and Bangladeshi native chickens and broiler with replacement of corn by rice in diet. Researches on their growth and other production parameters have not been adequately studied. Thus the objectives of the present study were to determine and compare the growth performance, tissue weights, nitrogen retention, free amino acids concentration in breast muscle, mRNA expression of IGF-I in liver, atrogin-1 and proteasome C2 sub unit in breast muscle of broiler and native chicken from Bangladesh and Japan (Niigata Jidori) by using different level of rice instead of corn in their diet. In the first experiment, we studied the effects of rice in different level (0%, 50% and 100% instead of corn) in diet to compare the growth performance, feed intake and feed conversion ratio of broiler (Cobb 500) and native chicken from Bangladesh. A total of 360 (180 native and 180 Cobb 500) one-day-old mixed-sex chickens were randomly allotted to three treatments (T), namely T_1 (Based on corn, 0% rice), T_2 (50% corn and 50% rice), and T_3(0% corn, based on rice 100%) with three replicates for each treatment (20 birds per replicate). The experimental birds were fed ad libitum diet with free access to drinking water. Data were analyzed by using SPSS based on 2×2 factorial design. Initial body weight (day old chicken) of broiler chicken were 42.33, 41.67, 43.33g and native chicken were 29.67, 31.00, 30.33g for T_1, T_2, and T_3 feeding group respectively. After five weeks body weight for broilers were 1251, 1266, 1287g and for native chickens were 297.67, 314.33, 317.67g for T_1, T_2, and T_3 feeding group respectively. Body weight gain in broiler for T_1, T_2, and T_3 feeding group were 1208.67, 1224.33, 1244.67g and 268, 283.33, 287.34g were for native chicken respectively. The average daily gain (ADG) during five weeks period were 34.5, 34.98, and 35.53g in broiler for T_1, T_2, and T_3 feeding group, whereas 7.65, 8.09 and 8.20g in native chicken for T_1, T_2, and T_3 feeding group respectively. Feed intake of broiler chicken at five weeks were 2126, 2132, 2147g and native chicken were 1001, 1057, 1051, for T_1, T_2, and T_3 feeding group respectively. Feed conversion ratio (FCR) was 1.76, 1.74, 1.72 for broiler chicken and 3.78, 3.73, 3.65 for native chicken in different treatment (T_1, T_2, and T_3) respectively. After five weeks, the results showed that all treatments of broiler chicken groups had higher body weight gain, feed intake, FCR, and average daily gain compared to native chicken. In the second experiment, we compare the growth performance, tissue weight, nitrogen retention and mRNA expression of Japanese native chicken (Niigata Jidori) and Chunky broiler. Day old chicks were reared under identical environmental conditions in the same house for 2 weeks with free access to feed (commercial broiler grower containing 22 % CP and 3050 kcal ME/kg DM) and water. Twenty birds of 14-days-old (10 Niigata Jidori and 10 Chunky broilers) were individually housed in battery cages with wire-mesh flooring and had free access to feed and water during the 2week experimental period. The birds were kept under 24h lighting programs throughout the experiment. The temperature was maintained at 29˚C on the first day, and lowered by 1˚C every 3 days, to a final temperature of 24˚C. Body weight gain (BWG), and feed intake (FI) were recorded weekly and feed efficiency (FE) was calculated from BWG divided by FI. Growth performance, nitrogen retention, concentrations of free amino acids in muscles, as well as mRNA expression of liver IGF-1, breast muscle atrogin-1, and proteasome C2 subunit were determined. Body weight gain, feed intake, and feed efficiency were significantly higher in broilers than that of Niigata Jidori. Muscle weights (breast and thigh) and nitrogen retention were significantly higher in broilers than that of Niigata Jidori. Concentrations of free amino acids, viz., Asp Glu, Ala, Cys, Tyr, Lys, and Arg in breast muscle were significantly higher in broilers than that of Niigata Jidori. However, there were similar concentrations for Thr, Ser, Gly, and Val, Met, Ile, Leu, Phe, and His in broilers and Niigata Jidori. No significant differences were found in mRNA expressions of liver IGF-I, breast muscle atrogin-1, and proteasome C2 subunit between broilers and Niigata Jidori. The growth performance of broiler and Niigata Jidori varied significantly, mRNA expression related to protein metabolism between the two breeds were same. In conclusion, rice could be considered as an alternative material of corn in broiler and native chicken diet without detrimental effect on growth performance. The growth performances in broiler was significantly higher due to their genotype. These researches could be beneficial for poultry industries and rural households who are involved in commercial and native chicken production. However, further research is needed to identify the factors which are responsible for enhancing growth performances, nitrogen retention, concentrations of free amino acids in muscles, as well as mRNA expression of liver IGF-1, breast muscle atrogin-1, and proteasome C2 subunit in broiler and native chickens.","subitem_description_type":"Abstract"}]},"item_6_description_53":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"新大院博(農)甲第207号","subitem_description_type":"Other"}]},"item_6_dissertation_number_52":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"13101甲第4776号"}]},"item_6_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"ETD"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Rahman, Mohammad Ataur"}],"nameIdentifiers":[{"nameIdentifier":"177982","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-08-31"}],"displaytype":"detail","filename":"r1fak207.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://niigata-u.repo.nii.ac.jp/record/33989/files/r1fak207.pdf"},"version_id":"c071ab36-bf0e-4f73-b519-c5911ba2c259"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-08-31"}],"displaytype":"detail","filename":"r1fak207_a.pdf","filesize":[{"value":"143.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨","url":"https://niigata-u.repo.nii.ac.jp/record/33989/files/r1fak207_a.pdf"},"version_id":"50409ce8-3e30-4f2e-9c95-0a01b4bf23bf"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Differences in Growth Performance and Protein Metabolism-Related Parameters of Broiler Chickens and Native Chickens (Niigata Jidori)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Differences in Growth Performance and Protein Metabolism-Related Parameters of Broiler Chickens and Native Chickens (Niigata Jidori)"}]},"item_type_id":"6","owner":"1","path":["455","564"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-08-31"},"publish_date":"2020-08-31","publish_status":"0","recid":"33989","relation_version_is_last":true,"title":["Differences in Growth Performance and Protein Metabolism-Related Parameters of Broiler Chickens and Native Chickens (Niigata Jidori)"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T04:04:17.970710+00:00"}
