Abstract
A method for selectively culturing the multiparout meat goat line includes choosing basic group of existing multiparous meat goats, closed reproduction, choosing the excellent descendants to form new basic group, closed reproduction, choosing the excellent descendants to form core group, closed reproduction and choosing excellent descendant individuals.
Description
Technical field:
The present invention relates to a kind of method of animal breeding.
Background technology:
For a long time, the reproduction rate of high-quality meat goat is low, and goat production cost height has influenced the economic benefit that meat goat is cultured to a certain extent.
Summary of the invention:
The object of the present invention is to provide that a kind of fertility is strong, the selection of the multiparous new strain of meaty goat of quality better.
Technical solution of the present invention is:
A kind of selection of multiparous new strain of meaty goat is characterized in that: comprise the following steps:
1. from meat goat, selected works polyembryony meat goat underlying group;
2. the polyembryony meat goat underlying group of selected works being carried out locking breeds;
3. from step 2. locking to breed first and second tire lambing number average of choosing ewe the offspring more and in the fast excellent individual of lamb early growth and development, set up underlying group again;
4. will carry out locking through the underlying group that 3. step is set up and breed, and it is more and in the fast excellent individual of lamb early growth and development to breed first and second tire lambing number average of choosing ewe the offspring from its locking, sets up core group again;
5. will carry out locking through the core group that 4. step obtains and breed, and it is more and in the fast excellent individual of lamb early growth and development to breed first and second tire lambing number average of choosing ewe the offspring from its locking, obtains multiparous new strain of meaty goat.
3., 4., 5. it is more and during in the fast excellent individual of lamb early growth and development to choose first and second tire lambing number average of ewe in step, can also earlier determine the polyembryony gene with the gene analysis method, gene molecule marking method is more and choose the individuality that clearly has the polyembryony gene the fast excellent individual of lamb early growth and development from first and second tire lambing number average of ewe again.
3., 4., 5. it is more and during in the fast excellent individual of lamb early growth and development to choose first and second tire lambing number average of ewe in step, can also determine the polyembryony gene with the gene analysis method earlier, and make the polyembryony genetic chip, use biochip technology more and the fast excellent individual of lamb early growth and development, choose the individuality that clearly has the polyembryony gene again from first and second tire lambing number average of ewe.
The present invention effectively improves the reproduction rate of meat goat, reduces the ewe production cost, improves the culturing economic benefit of meat goat, and can reduce ewe and raise quantity, and can save feed-use grain, and promote the meat goat batch production to produce, quicken the meat goat industrialization process.The multiparous new strain of meaty goat of setting up, the average lambing percentage of the every tire of multiparity ewe reaches 350%, and meat performance meets the meat breed requirement fully.
Below in conjunction with embodiment the present invention's invention is described further.
Embodiment:
Embodiment 1:
A kind of selection of multiparous new strain of meaty goat comprises the following steps: successively
1. from meat goat, selected works polyembryony meat goat underlying group;
2. the polyembryony meat goat underlying group of selected works being carried out locking breeds;
3. from step 2. locking to breed first and second tire lambing number average of choosing ewe the offspring more and in the fast excellent individual of lamb early growth and development, set up underlying group again;
4. will carry out locking through the underlying group that 3. step is set up and breed, and it is more and in the fast excellent individual of lamb early growth and development to breed first and second tire lambing number average of choosing ewe the offspring from its locking, sets up core group;
5. will carry out locking through the core group that 4. step obtains and breed, and it is more and in the fast excellent individual of lamb early growth and development to breed first and second tire lambing number average of choosing ewe the offspring from its locking, obtains multiparous new strain of meaty goat.
Embodiment 2:
As different from Example 1: it is more and during in the fast excellent individual of lamb early growth and development 3., 4., 5. to choose first and second tire lambing number average of ewe in step, can also earlier determine the polyembryony gene with conventional gene analysis method, conventional again gene molecule marking method is more and choose the individuality that clearly has the polyembryony gene the fast excellent individual of lamb early growth and development from first and second tire lambing number average of ewe.All the other are with embodiment 1.
Embodiment 3:
As different from Example 1: it is more and during in the fast excellent individual of lamb early growth and development 3., 4., 5. to choose first and second tire lambing number average of ewe in step, can also determine the polyembryony gene with conventional gene analysis method earlier, and make the polyembryony genetic chip, use conventional biochip technology more and the fast excellent individual of lamb early growth and development, choose the individuality that clearly has the polyembryony gene again from first and second tire lambing number average of ewe.All the other are with embodiment 1.
Claims (3)
