Abstract/ Executive Summary:

The study was aimed to observe the nutritive value of concentrate used in different dairy farms at peri-urban areas of Chittagong, Bangladesh. Ten (10) different concentrate feeds were randomly selected from ten different farms which analyzed for moisture, dry matter (DM), crude protein (CP), crude fiber (CF), nitrogen free extracts (NFE), ether extracts (EE), total ash (TA) and acid insoluble ash (AIA) and requirements of concentrate for unit production of milk was calculated. It was found that the nutritive value of individual feed concentrate of each farm varied significantly. The observed proportion of using feed ingredients was also significantly different among the farms. Finally, it may be summarized that the concentrate mixture used by the different farmers of peri-urban areas of Chittagong was different in regards to chemical composition, ingredients and amount required for milk production.

Program Area: Quality and Nutrition

Commodity: Feed

Objectives:

To determine nutritive value of concentrate feed using in different farms and amount of concentrate feed offered in relation to milk production.

Methodology:

Ten dairy farms were selected from peri-urban areas of Chittagong district based on good transportation facilities from where ten concentrate mixture samples, one from each farm, were collected. Approximately 500 grams of sample was collected from each farm, wrapped up by polythene bag and preserved in the laboratory for chemical analysis. Samples were subjected to grind to make it homogenous powder. Later on, it was mixed properly and exposed to shade to cool down for better sampling. The experimental samples were subjected to proximate analysis for moisture, dry matter (DM), crude protein (CP), crude fiber (CF), ether extracts (EE), total ash (TA), nitrogen free extract (NFE) and acid insoluble ash (AIA) following the method described by the Association of Official Analytical Chemist where all analysis were done in triplicates. Descriptive statistics were used to determine different concentration of feed ratio of chemical composition in different farms after that one sample t-test was used to determine any significant difference in different concentration of feed of chemical analysis by using in different farms. Percentage distribution was used to determine ingredients used in different farms and X² test were used to test of significance of using observed proportion of different ingredients. Statistical packages SPSS 16.0, R 2.14.0 was used during analysis and 5% level of significance was considered.

Achievement/Findings:

Nutritive status of different farms in the study area varied in composition, ingredients of feed and their amount required for unit milk production, which hampered the productive performances of cows.
