我國科研工作者育成肉牛新品種“華西?!?/h2>

據(jù)新華社北京8月9日電 歷經(jīng)43年協(xié)同攻關(guān),我國科研工作者育成了具有自主知識產(chǎn)權(quán)的肉牛新品種“華西?!保@將提升肉牛種業(yè)競爭力,對于推動產(chǎn)業(yè)發(fā)展、農(nóng)牧民增收具有深遠(yuǎn)意義。

這是記者9日從中國農(nóng)業(yè)科學(xué)院北京畜牧獸醫(yī)研究所了解到的消息。

中國農(nóng)科院副院長劉現(xiàn)武表示,近年來我國肉牛生產(chǎn)總體保持增長態(tài)勢,生產(chǎn)水平逐步提升。但也要看到,牛肉產(chǎn)量還不能完全滿足消費(fèi)快速增長需要。原因主要是我國肉牛業(yè)起步晚,品種生產(chǎn)性能與國際先進(jìn)水平有較大差距,養(yǎng)殖機(jī)械化程度和生產(chǎn)效率等方面也有待提升。

據(jù)了解,中國農(nóng)科院牧醫(yī)所牛遺傳育種科技創(chuàng)新團(tuán)隊組織全國優(yōu)勢育種隊伍,持續(xù)多年協(xié)同攻關(guān),并在多個省份進(jìn)行示范推廣,育成了肉牛新品種“華西?!薄T撈贩N于2021年12月通過國家畜禽遺傳資源委員會審定。

據(jù)悉,“華西牛”既適應(yīng)我國牧區(qū)、農(nóng)區(qū)及北方農(nóng)牧交錯帶,也適應(yīng)南方草山草坡地區(qū)。成年公牛體重達(dá)900公斤,成年母牛550公斤以上,屠宰率62.39%,凈肉率53.95%,平均育肥期日增重達(dá)1.36公斤,主要生產(chǎn)性能達(dá)到國際先進(jìn)水平。

農(nóng)業(yè)農(nóng)村部種業(yè)管理司二級巡視員謝焱表示,“華西?!笔谴蠹倚笥N的一個重大代表性成果。在種群性能上,具有生長速度快、適應(yīng)性強(qiáng)的優(yōu)勢;在核心技術(shù)上,實現(xiàn)了全基因組選擇技術(shù)的突破;在組織機(jī)制上,成立了育種聯(lián)合會并以實體形式運(yùn)行,有機(jī)整合了育種企業(yè)、科研機(jī)構(gòu)等優(yōu)勢單位力量。

中國農(nóng)科院牧醫(yī)所副所長李俊雅表示,肉牛作為典型的大家畜,世代間隔長、繁殖效率低,加上生產(chǎn)模式復(fù)雜,育種數(shù)據(jù)收集難度大?!叭A西牛”的成功培育,得益于多方發(fā)力、聯(lián)合育種和科技創(chuàng)新。
