| ABSTRACT Donganyellow chicken (Gallus gallusdomesticus, DYC) is one of the famous native breeds of Hunan province in China. It is the first time that the complete mitochondrialgenome sequence of DYC was reported. The total length of the mtDNA is16, 786bp. It contains 22transfer RNA genes, 2 ribosomal RNA genes,13 protein-coding genes and 1 D-loop region. The overall composition of the mtDNA is 30.27% for A, 23.74% for T, 32.50% for C and 13.49% for G. Phylogenetic analyses using N-J computational algorithms showed that the analyzed20Galliformes species are divided into three major clades: Phasianidae, Numidiidae and Odontophoridae. In addition, our work confirmed that DYCand Taoyuan chickenhave a closegenetic relationship with fellow tribal members Xuefeng... |

| ABSTRACT In order to find out the main factors influenced the hatchability and improve the hatchability of the windowed chicken eggs at stage X, several experiments were made on the basis of the former patent of eggshell windowing methods on equatorial plane, such as cutting and sealing techniques, air cell recovering, laying position immediately after sealing, as well as the injection volumes into the subgerminal cavity of the blastoderm. The result showed that:1) the best sealing material combination was straw powder (SP) and instant glue (IG); 2) there was a highly positive correlation between air cell rate and hatchability; 3) the highest hatchability increased to 71.6% when the eggs were windowed and sealed with IG dropped firstly and then SP... |
