Abstract:

The study was conducted to evaluate the nutritional value of spray-dried chicken plasma (SDCP) in piglets.A single factor design was adopted in this experiment.A total of 24 healthy crossbred “Duroc × Landrace × Yorkshire” barrows with an initial body weight of (24.96±1.05) kg were randomly allotted into 3 dietary treatments with 8 replicates per treatment.The 3 diets were N-free diet,corn-soybean basal diet and SDCP-diet (40% protein of basal diet were substituted by SDCP).After 6 days adaptation,all feces and urine from 24 piglets were collected for 4 days to determine the nutrient digestibility and availability.When the experiment ended,all piglets were euthanized and slaughtered to collect ileal digesta for determining apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of amino acids.The results showed that crude protein content of SDCP reached up to 69.36%,lysine content was 4.53%,methionine content was 1.65%,and lysine∶methionine∶tryptophan∶threonine=100∶36∶30∶91,which closed to the ideal protein animo acids model in pig.The apparent digestibility energy of SDCP was 16.02 MJ•kg-1,and the apparent metabolizable energy was 15.39 MJ•kg-1;apparent and true digestibility of crude protein were 87.58% and 91.11%,respectively;standardized ileal digestibility of all amino acids other than glycine were higher than 80%.Overall,spray-dried chicken plasma is a superior animal protein resource.
