【摘要】：【目的】羔羊前60 d生長(zhǎng)發(fā)育較快,研究0~60日齡新吉細(xì)毛羊生長(zhǎng)發(fā)育規(guī)律,為生產(chǎn)中早期飼養(yǎng)提供理論依據(jù)。【方法】測(cè)定新疆塔城種羊場(chǎng)613只新吉細(xì)毛羊羔羊初生、10、20、30、40、50和60日齡的體重,分析不同日齡段羔羊的生長(zhǎng)發(fā)育規(guī)律及不同群別對(duì)羔羊生長(zhǎng)的影響�！窘Y(jié)果】新吉細(xì)毛羔羊的日增重和相對(duì)生長(zhǎng)速度0~10日齡最快,20~50日齡下降,50~60日齡大幅下降,可將新吉細(xì)毛羔羊的生長(zhǎng)分為3個(gè)階段,分別為0~10日、20~50日齡及50~60日齡。【結(jié)論】0~10日齡,羔羊生長(zhǎng)發(fā)育很快,必須讓羔羊吃上初乳以及應(yīng)加強(qiáng)母羊的哺乳。20~50日齡是新吉細(xì)毛羔羊生長(zhǎng)發(fā)育較快的時(shí)期,應(yīng)對(duì)羔羊加強(qiáng)飼養(yǎng)管理和滿足其營(yíng)養(yǎng)供給。飼養(yǎng)管理較好的羊群羔羊生長(zhǎng)快,日增重高。
[Abstract]:[objective] to study the growth and development of Xinji fine wool sheep aged 0 ~ 60 days in the first 60 days, and to provide theoretical basis for early breeding in production. [methods] the birth weight of 613 Xinji fine wool lambs at Tacheng breeding farm in Xinjiang was measured, 10, 20, 30, 40, 50 and 60 days old, respectively. The growth and development of lambs at different ages and the effects of different populations on the growth of lambs were analyzed. [results] the daily gain and relative growth rate of Xinji fine wool lambs were the fastest, 20 鈮，
