Abstract/ Executive Summary:

An investigation was conducted on 540 scavenging chickens of two age groups (below 6 month and above 6 month) taking equal number from each of 6 upzilas (sub-district) under 4 districts in 3 seasons (Summer, Winter and Rainy season). The birds were collected from farmer`s house between 4:0 and 5:0 pm. Collected birds were slaughtered and dissected to collect different parasites from suspected organs. Crop and gizzard contents (CGC) were collected for nutritional analyses. CGC was processed and analyzed for proximate components, calcium (Ca) and phosphorous (P). The CGC contained 2678 Kcal/kg DM TME, 11.72% CP, 0.41% Ca and 0.34% P. Seasonal variation had significant effect on TME availability but not on CP content. Seasons, areas and their interactions had significant effect on Ca availability. Availability of Ca and P to younger birds was fewer than that of to aged birds, but reverse result was found for TME. It was concluded that all scavenging birds were under deficient nutritional status.

Commodity: Chicken

Objectives:

To evaluate of nutritional status of village chicken in different seasons.

Methodology:

An investigation was conducted on 540 scavenging chickens of two age groups (below 6 month and above 6 month) taking equal number from each of 6 upzilas (sub-district) under 4 districts in 3 seasons (Summer- March to June; Winter-November to February and Rainy season-July to October). The selected locations were Netrokona-mohongonj (NM), Serpur- Jhenaigati (SJ), Sirajgonj-Raigonj (SR), Sirajgonj-Sadar (SS), Gaibandha-Sundargonj (GS) and Gaibandah-Palashbari (GP). The birds were purchased from farmer's house between 4:0 and 5:0 pm. Collected birds were slaughtered and crop and gizzard contents (CGG) was collected for nutritional analyses. The CGC samples were dried, grounded and analyzed separately for proximate components, calcium (Ca) and phosphorous (P) contents. The proximate components (Moisture, Crude Protein, Crude Fiber, Ether Extract, Ash and Nitrogen Free Extract) were determined by the methods of AOAC. Calcium (Ca) and Phosphorus (P) content of the samples was also determined using the method. Each Sample was replicated twice to have the proximate components. The true metabolizable energy (TME) of CGC was determined by indirect method. According to Wiseman, TME= 3951 +54.4EE- BB.7CF-40.8 Ash; Where; EE= % of Ether Extract, CF= % of Crude Fibre, Ash= % of Ash and TME= True Metabolizable Energy, Kcal/kg Dry matter(DM). The statistical analyses of the data on different parameters were performed by the analysis of variance corresponding to a 2 (Age group) x 3 (Season) x 6 (Areas) x 15 (Replication) factorial experiment. Four factor RCBD statistical analysis method was used from MSTAT package Program.

Achievement/Findings:

The results of the study reveal that all scavenging birds were under deficient nutritional status. However, the interaction of age, season, and area should be given utmost importance to deal with nutritional status of scavenging chicken in rural areas of Bangladesh.
