Abstract
Eastern treasured blackhead sheep selection, selection is：Using boer goat as male parent, Macheng black goat is female parent, is hybridized, and then traversed by, homogeneity apolegamy, swarm robotic system seed selection must be eastern precious blackhead sheep.The method have the advantages that：Consistent with the precious blackhead sheep face shaping in the east of this method seed selection, lambing percentage is high, and meat flavour is without fishy smell, and meat production is high.Eastern treasured blackhead sheep is significantly better than Macheng black goat in terms of growth and meat production, reproductive performance, it is resistance to it is thick raise, it is disease-resistant it is degeneration-resistant in terms of be better than boer goat.
Description
Technical field
The present invention relates to sheep selection.
Background technology
At present, existing blackhead sheep general appearance shape is inconsistent, and lambing percentage is low, there is fishy smell, and meat production is low.
The content of the invention
The purpose of the present invention is inconsistent aiming at existing existing blackhead sheep general appearance shape, and lambing percentage is low, meat flavour
There are fishy smell, the low deficiency of meat production, and provide a kind of face shaping unanimously, lambing percentage is high, and meat flavour is without fishy smell, meat production
The precious blackhead sheep selection in high east.
Selection of the present invention is：
A, hybridization
Using boer goat as male parent, Macheng black goat（Cultivation Co., Ltd of Wuhan farmer family provides）For female parent, carry out miscellaneous
Hand over, obtain first-filial generation；
B, seed selection
First-filial generation selection standard is:6 monthly age of lamb body weight reaches 25 more than kg, carcass weight 12-15 kg, dressing percentage 48% with
On；Ram body weight 60 of growing up more than kg, more than the kg of ewe 45；Average lambing percentage 180%~200%, face shaping is that hair color is black
Head not holding any government official post；
C., homogeneity is matched
The first-filial generation of selection standard is up to, second filial generation is produced by homogeneity apolegamy；
D, traversed by
The second filial generation of selection standard is up to, then by traversed by；
E., swarm robotic system seed selection
Seed selection reaches the offspring for reaching selection standard but the composition underlying group of selection standard from traversed by offspring, in underlying group
With locking with the open swarm robotic system method being combined, swarm robotic system seed selection is carried out；Until hair color blackhead not holding any government official post's dimensionally stable,
As eastern precious blackhead sheep.
2nd, the precious blackhead sheep selection in east according to claim 1, it is characterised in that not up to selection standard requirement
Macheng black goat of the miscellaneous generation again with original basis group is returned, and obtains miscellaneous two generation.
The method have the advantages that：Consistent with the precious blackhead sheep face shaping in the east of this method seed selection, lambing percentage is high, and meat flavour is without fishy smell, production
Meat performance is high.Eastern treasured blackhead sheep is significantly better than Macheng black goat in terms of growth and meat production, reproductive performance, it is resistance to it is thick raise,
It is disease-resistant it is degeneration-resistant in terms of be better than boer goat.
Embodiment
Eastern treasured blackhead sheep selection is：
Eastern treasured blackhead sheep selection, it is characterised in that selection is：
A, hybridization
Using boer goat as male parent, Macheng black goat（Cultivation Co., Ltd of Wuhan farmer family provides）For female parent, carry out miscellaneous
Hand over, obtain first-filial generation；
B, seed selection
First-filial generation selection standard is:6 monthly age of lamb body weight reaches 25 more than kg, carcass weight 12-15 kg, dressing percentage 48% with
On；Ram body weight 60 of growing up more than kg, more than the kg of ewe 45；Average lambing percentage 180%~200%, face shaping is that hair color is black
Head not holding any government official post；
C., homogeneity is matched
The first-filial generation of selection standard is up to, second filial generation is produced by homogeneity apolegamy；
D, traversed by
The second filial generation of selection standard is up to, then by traversed by；
E., swarm robotic system seed selection
Seed selection reaches the offspring for reaching selection standard but the composition underlying group of selection standard from traversed by offspring, in underlying group
With locking with the open swarm robotic system method being combined, swarm robotic system seed selection is carried out；Until hair color blackhead not holding any government official post's dimensionally stable,
As eastern precious blackhead sheep.
Macheng black goat of the miscellaneous generation for selection standard requirement again with original basis group is not reached to be returned, and obtains miscellaneous two generation.
The new varieties of the precious blackhead sheep in east of institute's seed selection（System）Sheep appearance traits are basically identical, incidence hair black, body body
Hair white；Constitution is solid, and build is big, and structure is well-balanced, and back of the body waist is straight, and rear quarters is plentiful, and four limbs are higher and sturdy, and whole body is into tubbiness
Structure；Grow up ram body weight 65-75kg, adult ewe 45-55 kg；6 monthly ages public affairs lamb is 30 kg, and ewe lamb is 25 kg；12 monthly ages
Ram body weight 40-45 kg, ewe 30-35 kg；Average lambing percentage 210%, wherein reaching 230% through producing ewe.Public 6~August of lamb
Age fattening period daily gain 120-150g, dressing percentage surpasses 48%.Eastern treasured blackhead sheep is significantly better than Macheng in terms of growth and meat production
Black goat, reproductive performance, it is resistance to it is thick raise, it is disease-resistant it is degeneration-resistant in terms of be better than boer goat.
