Abstract/ Executive Summary:

The study was planned to determine morphological traits of indigenous naked neck (Nana) and full feathered (nana) chicken, market availability, live weight and price of Nana, nana, broiler (Br), and eggs from exotic and indigenous chickens in Gazipur and Savar, Dhaka, and meat yield of three genetic groups (Nana, nana, and Br). There was a huge variation in morphological traits of Nana and nana chickens considering live weight, length of shank, body conformation, wattle, and comb type, and colour of comb, skin, beak, shank, wattle, plumage, feather, egg shell, and egg weight. However, Nana exhibited single and red comb, whereas nana exhibited single, rose, pea, and red comb. The proportionate market availability and body weight of Br, and egg availability and weight of exotic chicken was higher with a lower price in comparison with Nana and nana chicken. However, availability of nana and its egg was higher than Nana (P<0.001).The highest breast and breast: dark meat was obtained in Br, followed by that in Nana and nana, respectively (P<0.001). The other meat yield traits were almost similar among the three genetic groups (P>0.05). Nana was tended to be better than Br for dark meat, thigh meat, and giblet weight. Therefore, the present study suggests conserving and improving Nana for poultry production in the tropics.

Keywords: Bangladesh, Chickens, Egg, Market availability, Meat yield, Price.

Location: Savar (Dhaka), Gazipur area, Bangladesh

Start Date: 00-01-2012

End Date: 00-06-2012

Program Area: Animal Health and Management

Commodity: Poultry

Objectives:

The proposed research work was aimed at assessing morphological traits, information on market availability and price of indigenous naked and full feathered chickens, and its products to conserve and improve their products in tropical climate.

Methodology:

The present study was conducted based on the availability, weight, price, morphology and meat yield traits of various types of chicken obtained in different markets of Gazipur and Savar areas in Bangladesh. The two study areas were selected because of availability of Nana, nana and Br, and good communication. A pre-tested schedule was prepared considering number of chickens in selected areas, live weight of chicken and sale price. The survey schedule was used in collecting information obtained by counting the availability of chicken population, individual live weight, and sale price per kg in case of naked neck (Nana), full feathered (nana) and broiler (Br) in the study areas. All the chickens belonging to Nana and nana, irrespective of sex and live weight were closely observed to quantify various morphological traits; live weight, length of body, shank, wattle, and comb type and colour, colour of skin, beak, shank, wattle, plumage, feather, egg shell, and egg weight. Representative birds of three different said genetic groups were selected to determine morphological and meat yield traits. Meat yield traits were recorded by slaughtering and eviscerating the parts of dressed meat of three chicken genetic groups. Data were collected strictly and carefully from January to June 2012. The collected data were summarized and scrutinized, and then recorded in master sheets. The recorded data were analysed using GENSTAT statistical computer package program in completely randomized design (CRD). LSD (Least significance difference) value was used to find out the significant difference between means. Availability of egg was analysed using χ²test.

Achievement/Findings:

The present study reveals that indigenous naked neck, and full feathered chicken exhibited huge variation in morphological traits. However, Nana exhibited single and red comb, whereas nana exhibited single, rose, pea and red comb. The highest number of chickens was recorded in broiler followed by nana and Nana, respectively. Broiler showed the highest body weight followed by Nana and nana. However, indigenous chicken was superior to broiler in respect of sale price. The number and weight of exotic chicken egg was higher with a lower sale price in comparison with indigenous chicken. Broiler yielded higher breast, breast: dark meat ratio than that of Nana and nana chicken. Of the indigenous chickens, Nana yielded higher meat than in nana chicken, even tended to be superior to Br in terms of higher dark, thigh and giblet meat yield. Therefore, the present study suggests conserving and improving Nana chicken for poultry production in Bangladesh. However, a comprehensive study considering different markets of Bangladesh is needed to make final conclusion.
