號(hào)稱(chēng)世界上長(zhǎng)得最快的綿羊
    發(fā)這個(gè)帖的起因是看到有網(wǎng)友問(wèn)”育肥羊日增重能達(dá)到多少”？雖然問(wèn)的是山羊，但是看一看綿羊最快的日增重紀(jì)錄就可發(fā)現(xiàn)，由于畜種的差異，山羊的日增重始終沒(méi)有綿羊快。塞浦路斯農(nóng)業(yè)研究院對(duì)于有相同生物學(xué)年齡并喂給同樣飼糧的山羊羔和綿羊羔進(jìn)行了一系列比較試驗(yàn)，結(jié)果表明綿羊羔生長(zhǎng)較快（綿羊羔為341克/天，山羊羔為244克/天）、每千克消耗的飼料較少（公綿羊羔為2.99-4.11，公山羊羔為3.91-4.93）。1998年，美國(guó)德克薩斯州對(duì)波爾山羊進(jìn)行集中統(tǒng)一性能測(cè)定的記錄為前20名測(cè)試公羊的日增重范圍為308克－431克，這對(duì)于山羊來(lái)說(shuō)是相當(dāng)高的日增重速度，但是還是不如下述的綿羊增長(zhǎng)快。
    美國(guó)密歇根州州立大學(xué)的綿羊教研室認(rèn)為這是”世界上生長(zhǎng)最快的綿羊“。MSU8130號(hào)公羔為薩福克品種，是作為評(píng)定該品種生長(zhǎng)速度和飼料轉(zhuǎn)化率的研究對(duì)象，出生于2008年2月8號(hào)，出生重為9公斤，68日齡斷奶重為54公斤。120日齡體重為92公斤，斷奶后在60天內(nèi)的生長(zhǎng)速度為730克/天，飼料轉(zhuǎn)化率為每公斤增重需要3.87公斤飼料，第12肋骨的脂肪層厚度為0.21英寸，眼肌面積為3.71平方英寸。另一只MSU8139號(hào)公羔的出生重為7公斤，65日齡斷奶重為42公斤，120日齡體重為90公斤，斷奶后60天內(nèi)的生長(zhǎng)速度為870克/天，飼料轉(zhuǎn)化率為每公斤增重需要3.39公斤飼料，第12肋骨的脂肪層厚度為0.21英寸，眼肌面積為3.53平方英寸。薩福克羊的圖片如下:

品種很重要的。不知道小尾寒羊如何

羅立2008

都還可以

這是實(shí)驗(yàn)室數(shù)據(jù)，現(xiàn)實(shí)中能達(dá)到嗎？

yqc19800601

誰(shuí)的羊有長(zhǎng)的這么快??？？

260174134

我考慮做育肥羊

這羊長(zhǎng)的好看又肥！不知道肉質(zhì)怎么樣！定是上品吧！

出生于2008年2月8號(hào)，出生重為9公斤  
       （9kg？？？怎么可能）

68日齡斷奶重為54公斤。120日齡體重為92公斤，斷奶后在60天內(nèi)的生長(zhǎng)速度為730克/天
       （比牛長(zhǎng)的還快啊，這些數(shù)據(jù)是哪來(lái)的）

Michigan State Claims World's Fastest Growing Sheep
USAgNet - 08/27/2008
The Sheep Research and Teaching Facility at Michigan State University (MSU) reports what it believes to be the "World's Fastest Growing Sheep."
MSU 8130, a Suffolk ram, was born on Feb. 8, 2008, as a 20-pound single. He was weaned on April 16, at an age of 68 days, and weighed 120 pounds. At 120 days of age, MSU 8130 tipped the scales at 203 pounds with a post weaning 60-day growth rate of 1.6 pounds per day.
MSU 8130 was part of a research study at MSU evaluating growth rate and feed efficiency in Suffolk ram lambs. Rams are fed for 42 days post weaning using feed intake recording equipment. MSU 8130 had a feed conversion rate of 3.87 pounds of feed per pound of gain. At 96 days of age, weighing 163 pounds, MSU 8130 was scanned using ultrasound and was found to have a 12th rib fat measurement of 0.21 inches and a loin eye area of 3.71 square inches.
Another ram, MSU 8139, born as a 16-pound twin on Feb. 11, was weaned at 93 pounds at 65 days of age. At 120 days of age, MSU 8139 weighed 199 pounds with a post weaning 60-day growth rate of 1.91 pounds per day. MSU 8139 had a feed conversion rate of 3.39 pounds of feed per pound of gain. At 114 days of age, weighing 184 pounds, MSU 8139 was scanned using ultrasound and was found to have a 12th rib fat measurement of 0.21 inches and a loin eye area of 3.53 square inches.
Both rams were sired by Culham ? Stevens 5BR155, the National Sheep Improvement Program Suffolk trait leading sire for both weaning weight and post-weaning gain.

生長(zhǎng)快的肉質(zhì)應(yīng)該不會(huì)好吧
