Description
Technical Field
The invention relates to the technical field of wild pheasant breeding, in particular to a wild pheasant artificial semen collection device and a wild pheasant semen collection method.
Background
Phasianidae birds are a very characteristic group in wild animal resources in China, China is the country with the most rare or endangered pheasants in the world, and the Phasianidae birds have the characteristics of being rich in species, special in species and many in endangered species, so that the Phasianidae birds not only provide provenances for cultivating excellent poultry, but also maintain the health of forest ecosystems. Due to the reasons of habitat loss, unreasonable utilization, foreign species invasion, climate change and the like, the problem of pheasant resource loss is very prominent. The distribution range of some unique endangered pheasants is rapidly shrunk, the population quantity is obviously reduced, and the ecological prospect of the population is great.
In the protection work of wild phasianidae birds, artificial insemination breeding is the most important and most common means at present. Regarding artificial insemination breeding work of wild phasianidae, the core work is artificial semen collection and artificial insemination impregnation technology, in the artificial semen collection work of the wild phasianidae, the traditional poultry semen collection device and the semen collection method are used at present, namely, firstly, both feet of a male phasianidae are bound, the periphery of a cloaca of the male phasianidae is disinfected, then the male phasianidae is massaged from the neck to the tail along hairs, meanwhile, the soft part of the side abdomen of the cloaca is touched, extrusion is carried out when a male phasianidae device is turned outwards, and then, the semen discharged from the cloaca is collected by an open collection cup.
Although semen collection can be achieved in such a manner, in further research, the inventor finds that semen collection of wild phasianidae birds by using the conventional poultry semen collection device is insufficient, and the method is specifically as follows:
in the process of semen collection of poultry, how to reduce the pollution problem in the semen collection process is a precondition for ensuring the semen quality, at present, in the semen collection of poultry provenance, in order to reduce the risk of semen pollution, the following methods are generally adopted:
firstly, feathers around the cloaca need to be cut off in feeding, so that the work of semen collection is facilitated, and more importantly, the pollution of the feathers around the cloaca to semen is prevented;
secondly, water and material are cut off about two hours before semen collection, so that the risk of feces discharge during semen collection is reduced;
thirdly, training semen collection staff's operating skill, removing in time the collection cup when the semen is discharged, avoiding excrement and urine to get into in the collection cup when the semen is discharged.
Even if the operation as above, in the actual semen collection process, the risk that the pollutant enters the collection cup can not be avoided, so when the pollutant enters the collection cup and the pollutant is not much or is not diffused greatly, the pollutant and the polluted semen are timely removed by using a suction pipe, a pair of tweezers and other tools.
The purity of the collected semen is ensured as much as possible by the above method, so that the above method is still used in the current wild pheasant semen collection work, and although the semen collection can be realized, in the actual semen collection work and further research, the inventor finds that the collection method has defects, such as the following:
because the wild pheasants live in the wild, feathers around cloaca cannot be cut off when sperm collection is carried out, otherwise the wild pheasants are difficult to survive in the wild; meanwhile, the diet of the adopted semen is difficult to control, and the great risk of defecation and urination exists before and after the semen collection process; moreover, because poultry is artificially raised, the poultry is fat in size and large in single semen discharge amount, when pollutants fall into the collecting cup, the polluted parts can be removed, and for wild pheasants, the single semen discharge amount is usually less, when the pollutants fall, the polluted parts and the uncontaminated parts are difficult to separate, so that the problem of low sperm survival rate in the semen collection work of the wild pheasants at present is caused.
Based on the above, for the work of semen collection of wild pheasants, the difficulty of ensuring semen purity is far higher than that of the work of semen collection of poultry, which is also a difficult problem of artificial propagation in the work of protecting wild pheasants at present, so that a collection device and a semen collection method suitable for the semen collection of wild pheasants, capable of improving the purity of collected semen and further ensuring the quality of semen are urgently needed to be designed at present.
