feed which mostly depends on the proper feedstuffs selection and the manufacturing
process. This study was undertaken to monitor the deviation of protein level
and the mechanical effects on different biofactors viz. protein, moisture, ash,
crude lipid and fiber in feed during manufacture. Samples were collected at
randomly and batch wise from the prominent feed industry during the production
period. Samples were collected from two different production level viz. Final
Mixer and Finished
Feed and third other sample
was prepared as Control Mixer
on the dry basis. All the samples were analyzed by using proper analytical procedure
in the laboratory of fish nutrition. The percentage of protein content was 17.9
in control mixer and 18.46 in final mixer which finally decreased to 17.03%
in finished feed. In control mixer ash content was 25.74 and 23.1% in final
mixer which increased in finished feed to 24.68%. Lipid content increased in
finished feed (6.1%) rather than the final mixer (5.95%) and the control mixer
(3.75%). However, crude fiber content decreased from control mixer to finished
feed thoroughly. Crude fiber content in control mixer was 7.4% which decreased
to 6.86 and 6.56% in final mixer and finished feed respectively. Again a relation
may be drawn between the moisture content and ash and lipid content with crude
fiber. By this study it was observed quality of feed is highly influenced by
quality machine.]]>Ahmed, S., A.F.M. Arifur Rahman, M.G. Mustafa, M.B. Hossain and N. Nahar,20127135140Al Mahmud, N., M.D.R. Hasan, M.B. Hossain and M.H.
