【摘要】：上個世紀(jì)末,毛用型羊開始向肉毛兼用和肉用型發(fā)展,而我省缺乏專門的肉用綿羊品種,但有群體巨大的小尾寒羊,東北細(xì)毛羊群體,如何按照現(xiàn)代動物遺傳理論,充分利用雜種優(yōu)勢,生產(chǎn)優(yōu)質(zhì)雜交商品肉羊,是我省乃自我國肉羊產(chǎn)業(yè)化發(fā)展的必由之路.雖然我省自上世紀(jì)90年代末以來,引進了杜泊.南肉美等多個專門的肉用綿羊品種,也開展了與地方品種進行雜交改良的許多工作,但始終沒有選出適合于本地肉羊產(chǎn)業(yè)化發(fā)展的最終雜交組合.因此,本次試驗測定了國外肉羊品種南非美利奴羊、杜泊羊與小尾寒羊、東北細(xì)毛羊的雜交一代羔羊的生長速度和產(chǎn)肉性能,并且進行對比分析。試驗隨機抽取南寒F1、杜寒F1、南北F1公母個30只以上,在同一飼養(yǎng)條件下飼養(yǎng),通過測定出生、3、6、9月的生長速度指標(biāo)和9月齡的產(chǎn)肉性能等指標(biāo),研究比較不同組合雜交羊的生產(chǎn)性能,從而為更好的選育出優(yōu)秀的雜交羊品種提供依據(jù)。結(jié)果表明:利用南非美利奴羊與小尾寒羊進行雜交,其F1代在生長性能和產(chǎn)肉性能上表現(xiàn)出優(yōu)異的雜交效果。證明利用南非美利奴羊與小尾寒羊雜交是提高肉羊生產(chǎn)水平的有效途徑。
[Abstract]:At the end of the last century, wool sheep began to develop towards both meat and wool and meat use. However, there were no special meat sheep breeds in our province, but there was a large population of small tail Han sheep and northeast fine wool sheep, how to follow the modern animal genetic theory. Making full use of heterosis to produce high-quality commercial crossbred mutton sheep is the only way for the industrialization development of meat sheep in our province. Although our province has introduced Duber since the late 1990s. Many specialized meat sheep breeds, such as Nanmeimei, have also carried out a lot of work on hybridization and improvement with local breeds, but the final hybrid combination suitable for the industrialization development of local meat sheep has not been selected. Therefore, the growth rate and performance of crossbred lambs of foreign mutton breeds Merino sheep, Dupo sheep, small tail Han sheep and northeast fine wool sheep were measured and compared with those of other mutton sheep breeds (South Africa Merino sheep, Duper sheep, small tail Han sheep and Northeast fine wool sheep). The experiment randomly selected more than 30 male and female of South Cold F _ 1, du Han F _ 1 and North and South F1 and raised them under the same feeding condition. The growth speed indexes of birth, 3, 6, 9 months and the performance of meat production at 9 months old were measured by measuring the growth speed of birth, 3, 6 and 9 months of age. The production performance of different combinations of hybrid sheep was studied and compared, so as to provide basis for better breeding of excellent hybrid sheep breeds. The results showed that the F _ 1 hybrid between South African Merino sheep and small tail Han sheep showed excellent hybrid effect on growth performance and meat production performance. It is proved that the cross between South African Merino sheep and small tail Han sheep is an effective way to improve the production level of meat sheep.
