Abstract

Aims: This experiment was conducted with the aim of investigating fractions of protein of some plant and animal protein sources using the CNCPS method. 

Study Design:  After preparing the desired feed items, the protein fractions of feed samples were determined.

Methodology: This experiment was conducted on sources of plant protein (soybean meal, rapeseed meal, and cottonseed meal) and sources of animal protein (poultry offal meal, fish meal and blood meal).The protein fractions of feed samples were determined by Licitra et al, 1996. These fractions were included non-protein nitrogen, true protein, soluble true protein, insoluble protein, soluble protein in neutral detergent, insoluble protein in neutral detergent but soluble in acid detergent and insoluble in acid detergent and attached.

Results: After testing, the amount of non-protein nitrogen (fraction A) in soybean meal, cottonseed meal and rapeseed meal was 8.52, 6.33 and 4.55%, and in poultry offal meal, fish meal and blood meal in slaughterhouses were 10.38, 13.63 and 16.08% of crude protein, the amount of B1 in soybean meal, cottonseed meal and rapeseed meal was 2.30, 3.32 and 13.68% respectively, and in poultry offal meal, fish meal and blood meal, in slaughterhouses were 3.45, 7.44 and 7.16% of crude protein respectively , the amount of B2 in soybean meal, cottonseed meal and rapeseed meal was 80.49, 77.50 and 68.40%, in poultry offal meal, fish meal and blood meal, respectively, 66.36, 55.03 and 61.66% respectively, the amount of B3 for soybean meal, cottonseed meal and rapeseed meal was 6.24, 2.63 and 9.11%, respectively, and poultry offal meal, fish meal and blood meal in slaughterhouses were 7.50, 6.74 and 11.91% of crude protein respectively , the protein C portion assumed in the rumen's indissoluble CNCPS system in soybean meal, cottonseed meal, and rapeseed meal was 2.45, 9.92, and 4.77%, respectively, in poultry offal meal, fish meal and blood meal, respectively, 12.21 , 17.16 and 3.18% of crude protein.

Conclusion: The results indicate that the use of CNCPS and NRC data for portion fractions of different feeds cannot be considered absolutely, and domestic research and results should be used to extract samples from different regions and different growth conditions, so that the dietary regimens With these foods, it's real and more balanced and with less waste of nutrients.
