“新吉”细毛羊改良当地绵羊的效果

The Effect of Improving the Local Sheep with the"Xinji"Fine-wool

实践证明,以"新吉"细毛羊为父本对东北细毛羊进行改良能够显著提高改良羊群的产毛性能,对原毛产量、净毛率、羊毛长度和细度的提高效果明显。改良率、羊毛长度和细度的提高效果明显。改良F_2代羊毛细度从东北细毛羊母本的60～64 s(24.3μm)提高到了66～70 s(20.7μm),羊毛长度从7.2 cm提高到8.1 cm,净毛率从38.5%提高到45.8%,原毛单产从4.0kg提高到5.1 kg。特别是净毛单产从1.54kg提高到2.34 kg,提高了0.80 kg,增产幅度高达51.95%。

The practice proved, Carries on the improvement take ＂xin ji＂ the fine-wool sheep as the male parent to the northeast fine-wool sheep to be able obviously to enhance the improvement flock of sheep to produce the wool performance. To the original gross output quantity, the scouring yield, the wool length and degree of fineness enhance the effect to be obvious.Iraproved the F2 generation of wool degree of fineness （24.3 μm） to enhance from northeast fine-wool sheep female parent 60 - 64 s to 66 - 70 s （20.7μm）. The wool length enhances from 7.2 cm to 8.1 cm, The scouting yield from 38.5% enhances to 45.8%, The original wool per unit area yield enhances from 4.0 kg to 5.1 kg. Specially only the wool per unit area yield enhances from 1.54kg to 2.34kg, enhanced 0.80kg, the production increase scope has reached as high as 51.95%.
