Abstract/ Executive Summary:

Meat and bone meal (MBM) is a potential source of animal protein for poultry. The study was undertaken to investigate the variations in the chemical composition of MBM available in different feed markets of Chittagong, Bangladesh. Secondary data from one hundred ten different MBM samples were analyzed in triplicate for dry matter (DM), crude protein (CP), crude fiber (CF), ether extract (EE) and total ash (TA) in the Poultry Research and Training Centre laboratory of Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh during 21st October 2014 to 2nd December 2016. Data were collected, compiled and analyzed. Results indicated that, there were wide ranges of variations in the chemical compositions for different parameters. DM varied from 91.9 to 98.7% and CP varied from 18.5 to 74.5%. Similarly, CF varied from 1.1 to 2.9% and EE varied from 7.5 to 45.0%. TA varied from 4.8 to 33.6%. There was a strong negative relationship between CP and TA (r=-0.831; R2=0.691; P<0.001). However, DM and TA were positively correlated (r=0.374; R2=0.139; P=0.003). It was concluded that, chemical composition of MBM is widely variable. Wet chemistry analysis is suggested before inclusion of MBM in the diets of dairy, poultry and pet animals.

Start Date: 00-01-2017

End Date: 00-06-2017

Program Area: Quality and Nutrition

Commodity: Nutrition

Objectives:

The current study, therefore, aims to investigate variations in the chemical composition of MBM to formulate balanced ration for poultry, pet and other monogastric animals.

Methodology:

Study area The study was carried out in the Department of Animal Science and Nutrition, Faculty of Veterinary Medicine, Chittagong Veterinary and Animal Sciences University, Khulshi, Chittagong-4202, Bangladesh during January to June of 2017. Collection of data During January to March, data related to proximate analysis of 110 MBM samples were collected. Name of the company, address, sample ID, receive data, DM, CP, CF, EE and TA parameters were collected from laboratory register during 21st October 2014 to 2nd December 2016. Finally, data were entered into an electronic spreadsheet, sorted and compiled for statistical analysis. Sorting was done according to date of receiving sample. After entering data into the spreadsheet, integrity of the data set was checked. Data missing with CP value (Although contained DM, CF, EE and TA) were not considered for the study purpose. The final database consisted of 110 samples. Out of 110 samples, 62 were selected for linear regression as they contained most of the proximate parameters (DM, CP, EE and TA) of interest. Data analysis Data were analyzed for descriptive statistics (mean, median, mode, maximum, minimum, standard deviation and standard error) for DM, CP, CF, EE and TA. One sample t-test was carried out using reference value to analyze the data in Stata (Stata/SE 14.1, StataCorpLP, 4905 Lakeway Drive, College Station, TX77845, USA). CP was predicted from TA, DM, EE using simple linear regression. Associations between CP, TA, DM and EE were determined using Pearson’s correlation coefficient. Statistical significance was accepted at P<0.05.

Achievement/Findings:

Current study indicates that, the quality of MBM is variable. Therefore, to formulate least cost balanced ration, MBM must be analyzed first in the laboratory and then incorporate it into dairy, poultry and pet rations.
