The Study On The Technology Of The Breeding And Propagating Porcupines Of Manpower

The porcupine have higher of edible value, medicine value, appreciates value and craft value, is a kind of economic wildlife, the market foreground to be very good. But at present have the problem that farming lack of the breeding technique, so the produce performance can not effectively develop. This study selected the healthy porcupine which from the Xiangxi in Hunan, You yang in Sichuan and caught in wild breeding generations as subjects by age groups gradual domestication. Observe the domestication degrees and the life habits and growth; for the anatomy of the penis and manpower breeding research.Experiment 1: porcupine by body size into four age groups: the porcupine weight over13kg was adult porcupine group, weight 5kg to 13kg was inferior -adult porcupine group, weight in 1kg to 5kg was juvenile porcupine group, the weight under 1kg was young porcupine Group, the same one Individual age group will be almost the size of a porcupine by a male and a female for a group or a male and two female for a group, and then kept separately domesticated. Domestication of the extent of growth and living habits found:1 .The Artificial propagation of the porcupine domestication degrees high than the wild porcupine, and in the wild porcupine, domesticated young porcupine high than that juvenile porcupine, the juvenile porcupine high than inferior-adult porcupine, inferior-adult porcupine high than adult porcupine.2. Porcupine has night activities, gregarious, location defecation habits.3. Porcupine growth speed, 6 to 14 months was the fastest growth period, development well, and low feeding costs.Experiment 2: Random selection of health and without relative of the adult porcupine, distribution with natural breeding, complex reproduction and reproduction of blood comparison .The study found: through the use of different gender ratio, male/female =1:1 the sex ratio of a "natural reproduction" is the best sex ratio. Through the use of "complex propagation", raise the porcupine fetal quantity. Through the use of "reproduction of blood comparison," the porcupine from births two fetal increase to three fetal a year, greatly reduces the porcupine breeding cycle, improve the porcupine of births-a year, thereby raising the porcupine manpower breeding efficiency. Experiment 3: used 12 porcupines, the mother equal, the method by system anatomy their reproductive systems anatomy. Entities with the naked eye and a microscope observation and measurement found:Porcupine is not strictly seasonal rut animals, the year of its activities are conducted from seasonal restrictions. No male porcupine scrotum, testicles in the groin; Epididymis is well-developed; epididymis tail packed column, and the length of 2 cm more drifting testis. Porcupine vice gonad very developed, which includes vesicles, prostate and urethral gland ball. There are pairs each gland. Female porcupines have type of double uterus. Its anatomical features and characteristics of the female anatomy coypu close, porcupine developed double uterus to pregnancy. When the mother porcupine estrus, ovarian surface 2 to 4 follicular development.
