| In order to study on applicability and quality of blue peafowl eggs 100 blue peafowl eggs and twelve healthy (male and female each six), one years old, blue peafowls were selected randomly from Hongxiang company of Jiayuguan in Hexi district. They were butchered together, were tested and were analyzed by blood physiological and biochemistry indices, eggs quality, eggs nutritional components, eggs volatile flavor substances etc. The results showed as below:1. Blood physiological and biochemistry indices: The blue peafowl's blood RBC, ALT, TP, TBA, AG, HBDH, Mg, MCH, ALP, CO2-M and MCV were 1.495×1012/L, 6.000U/L, 41.417g/L, 43.833umol/L, 22.421mmol/L, 89.667U/L, 0.510mmol/L, 79.166pg, 84.667U/L, 25.080mmol/L and 174.200 fL respectively. Compared with male and female blue peafowl, the male blue peafowl's RBC,ALT,TP,TBA were lower than female blue peafowl (P<0.05), AG were significantly lower than female blue peafowls (P<0.01). But the male blue peafowl's HBDH, Mg, MCH were higher than female blue peafowl (P<0.05), its ALP, CO2-M, MCV showed significant higher than female blue peafowl (P<0.01). Compared with Taihe silkies, blue peafowl's ALB, TP, ALP, LDH content were higher, but TCH was lower than Taihe silkies. All these results proved that blue peafowl had good nutrition, performance and applicability.2. Blue peafowl eggs quality: The average egg weight of blue peafowl eggs was 94.400±4.681g, egg shape index was 1.337±0.046, yolk index was 0.445±1.003, haugh unit was 74.033±2.534, pH was 7.120±1.852, proportion was 1.095±0.043, yolk/egg white was 99.879±12.141, eggshell thickness was 0.488±0.004mm. Compared with Jingbai eggs, the blue peafowl eggs was more in weight, its eggshell was thicker. The egg shape index, yolk index, haugh unit of blue peafowl were higher than Jingbai eggs.3.The normal nutrition composition of blue peafowl eggs: The average fat of blue peafowl eggs was 0.923±0.002g/100g, protein content was15.554±0.076g/100g, cholesterol content was 0.613±0.013g/100g. The phosphorus content was 0.032±0.056g/100g, the zinc content was19.690±0.043mg/100g, the selenium content was 0.060±0.001mg/100g, the manganese content was 1.340±0.012 mg/100g. The VC content was 30.300±0.016mg/100g, the VB1 content was 0.130±0.033mg/100g, the VB2 content was 0.410±0.003mg/100g, the VA content was 0.030±0.016mg/100g, the VE content was 0.020±0.007mg/100g. Compared with eggs of chicken and duck, blue peafowl eggs contented higher dry substance,protein,VC, zinc, selenium, manganese,but contented lower fat, cholesterol, phosphorus. Blue peafowl eggs displayed high protein, low fat, so it was excellent food from animals.4. Blue peafowl eggs amino acids, fatty acid compositions: the total amino acid was 13.04g/100g, the essential amino acids(EAA) was 5.52g/100g. The proportion of amino acids about blue peafowl eggs was reasonable, and abundant content, accord with FAO pattern. 15 kinds of fatty acid were extracted and identified, palmitic acid content was 27.98% and oleic acid content was 23.75%. In saturated fatty acid, the content of butyric acid and stearic acid were above 7%, other were all below 1%. The unsaturated fatty acid content was 55.84%, linoleic acid content was 10.73%, EPA content was 3.33%, DHA content was 5.18%. Monounsaturated fatty acid content was 29.39%, polyunsaturated fatty acid was 26.45% in blue peafowl eggs. Compared with eggs of chicken and duck, blue peafowl eggs was high content in unsaturated fatty acid and essential fatty acid include linoleic acid,EPA,DHA.5. Blue peafowl eggs volatile flavor materials: 60 volatile flavor materials were extracted and identified from blue peafowl eggs. The high relative content to volatile flavor materials include hexanal(25.65%), heptaldehyde(1.20%), nonanal(1.29%),propanone(13.41%), alcohol(10.24%), L-alanine ethyl ester(27.50%), 1-octene-3-ol(1.87), benzaldehyde(2.44%), eicosane(1.25%) etc. There were 19 volatile flavor materials more than Jingbai eggs in some condition, and the relative content higher than Jingbai eggs. Show that: blue peafowl eggs volatile flavor materials were abundant and special.
