Studies On The Reproductive Technique Of The Partridge

The technique of the electron microscopy examination and radioimmunoassay(RIA) were used to study the artificial insemination, the plasma hormone concentration of the female partridge in the different phases and the hatch in 240 partridge. The results and conclusions as follows: 1.The fertilization rates of artificial reached 91.7% at 4 days apart, and 89.7% every 5 days. The condition for the achievement was that 50j.il of diluted semen was deposited in 1.5-2cm depth of vagina. The effective sperm amount was from fifty million to a hundred million after the semen was diluted by the skim milk at 37t.The semen concentration was 2.417?.Sl8billion, its pH was 7.19?.21, the mobility was 0.85?.5, and the abnormal morphology rate was 12.7?.04%. 2. The shape and ultramicrostructure of the sperm were similar to those the poultry. The whole length of the semen was 99.25?.9~im; the length of the head and neck was 14.22?.91j.tm; the diameter of the bent pole was 1.25?.5~.im; the length of the tail was about 85.03?.1~im. (n6)0 3. Plasma concentrations of the thyroxin (T4) in the partridge gradually increased from puberty to the telophase of laying, but the concentration decreased and reached nadir on the end of laying. The thyroxin (T4) had an influence on the partridge transforming from the breeding season to the no-breeding season. 4. The hatch rate reached 93.36% in the zygote and the health rate of the young was 98.33%. The eggs averaged weight of 22.18g were stored in the condition of 13C , relative humidity of 70% for 10 days. The average weight of eggs was I 9.34g on the last day of hatch. The losing water rate wasl2.4%0...
