Summary of the invention:
The present invention is a purpose with the germ plasm resource creative utilization; Utilize modern genetic breeding and propagation technique, introduce external improved seeds boer goat, local milch goat and domestic improved seeds Chinese scholartree goat and hybridize, many at Chinese scholartree goat individuality; On the good basis of reproductive performance; Utilize the good performance of giving milk of good meat performance of boer goat and local milch goat, cultivate the high quality meat sheet strain with reddish tone characteristic of high yield, high-quality, and then adapt to the needs in international and domestic mutton sheep market.
Specific practice of the present invention is:
(1) the sheep kind is selected: the import boer goat, select outstanding Chinese scholartree goat and local milch goat;
(2) first cross combination: divide two groups; One group is the pairing hybridization between import bohr ram and the female Chinese scholartree goat; Produce F1 and set up paternal colony for ripple Chinese scholartree hybrid generation, another group is that import bohr ram and female local milch goat match each other, produces F1 and sets up maternal colony for ripple milk hybrid generation;
(3) raising technology: superovulation, artificial insemination and embryo transplantation;
(4) feeding and management: only will hybridize sheep, and by kind and sex subfield, adopt drylot feeding to feed and add the feeding manner of herding, the results of regular determination growth indexes is cultivated at any time and is observed;
The hybrid combination of (5) two generations; Select F1 for excellent individual hybridization in paternal line that obtains in the hybridization and the maternal colony; F2 for select in the individuality reddish tone characteristic and individual bigger ewe and bohr ram carry out 2 generation grading up; Select F4 to fix afterwards, form stable reddish tone meat goat strain for the individual traversed by of reddish tone.
(6) feeding and management: only will hybridize sheep, and by kind and sex subfield, adopt drylot feeding to feed and add the feeding manner of herding, the results of regular determination growth indexes is cultivated at any time and is observed;
The reddish tone meat goat strain of according to said method cultivating, meat performance is outstanding, and shows and grow soon, and the characteristic that reproduction rate is high, resistance against diseases is strong and environment-adapting ability is good is suitable on China's Mutton Sheep Industry, applying, and concrete cultivating process is seen accompanying drawing 1.
Description of drawings: accompanying drawing 1 shows boer goat, Chinese scholartree goat and local milch goat through after the 4 generations hybridization, and traversed by is fixed, and cultivates the schematic flow sheet of the reddish tone meat goat strain with three breedinesses.
Embodiment:
Select reddish tone goat, boer goat, Chinese scholartree goat and local milch goat individual at random, birth weight, 3 monthly ages, 6 monthly ages are heavily measured.Simultaneously, observe health status, adaptive capacity to environment and the resistance against diseases of lamb.Adopt one-way analysis of variance, relatively the difference condition of each different cultivars sheep index specifically sees attached list 1.
On the birth weight index, in the male and female sheep, boer goat is significantly higher than other three kinds (P＜0.05), and the reddish tone goat is significantly higher than Chinese scholartree goat and local milch goat (P＜0.05), difference not significantly (P＞0.05) between Chinese scholartree goat and the local milch goat;
On 1 monthly age body weight index, in the ram, reddish tone goat and bohr sheep difference is remarkable (P＞0.05) not, but the two all is significantly higher than Chinese scholartree goat and local milch goat (P＜0.05), and local milch goat is significantly higher than Chinese scholartree goat (P＜0.05); In the ewe, difference not significantly (P＞0.05) between reddish tone goat and the bohr sheep, difference not remarkable (P＞0.05) between Chinese scholartree goat and the local milch goat, reddish tone goat and bohr sheep are significantly higher than Chinese scholartree goat and local milch goat (P＜0.05).
On 3 monthly age body weight indexs, in the ram, reddish tone goat and bohr sheep difference is significantly (P＞0.05) not, difference not remarkable (P＞0.05) between Chinese scholartree goat and the local milch goat, and reddish tone goat and bohr sheep are significantly higher than Chinese scholartree goat and local milch goat (P＜0.05); In the ewe, bohr sheep and local milch goat difference is remarkable (P＞0.05) not, is significantly higher than reddish tone goat and local milch goat (P＞0.05), and the reddish tone goat is significantly higher than Chinese scholartree goat (P＞0.05) again.
