号称世界上长得最快的绵羊
    发这个帖的起因是看到有网友问”育肥羊日增重能达到多少”？虽然问的是山羊，但是看一看绵羊最快的日增重纪录就可发现，由于畜种的差异，山羊的日增重始终没有绵羊快。塞浦路斯农业研究院对于有相同生物学年龄并喂给同样饲粮的山羊羔和绵羊羔进行了一系列比较试验，结果表明绵羊羔生长较快（绵羊羔为341克/天，山羊羔为244克/天）、每千克消耗的饲料较少（公绵羊羔为2.99-4.11，公山羊羔为3.91-4.93）。1998年，美国德克萨斯州对波尔山羊进行集中统一性能测定的记录为前20名测试公羊的日增重范围为308克－431克，这对于山羊来说是相当高的日增重速度，但是还是不如下述的绵羊增长快。
    美国密歇根州州立大学的绵羊教研室认为这是”世界上生长最快的绵羊“。MSU8130号公羔为萨福克品种，是作为评定该品种生长速度和饲料转化率的研究对象，出生于2008年2月8号，出生重为9公斤，68日龄断奶重为54公斤。120日龄体重为92公斤，断奶后在60天内的生长速度为730克/天，饲料转化率为每公斤增重需要3.87公斤饲料，第12肋骨的脂肪层厚度为0.21英寸，眼肌面积为3.71平方英寸。另一只MSU8139号公羔的出生重为7公斤，65日龄断奶重为42公斤，120日龄体重为90公斤，断奶后60天内的生长速度为870克/天，饲料转化率为每公斤增重需要3.39公斤饲料，第12肋骨的脂肪层厚度为0.21英寸，眼肌面积为3.53平方英寸。萨福克羊的图片如下:

品种很重要的。不知道小尾寒羊如何

都还可以

这是实验室数据，现实中能达到吗？

谁的羊有长的这么快啊？？

我考虑做育肥羊

这羊长的好看又肥！不知道肉质怎么样！定是上品吧！

出生于2008年2月8号，出生重为9公斤  
       （9kg？？？怎么可能）

68日龄断奶重为54公斤。120日龄体重为92公斤，断奶后在60天内的生长速度为730克/天
       （比牛长的还快啊，这些数据是哪来的）

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.

生长快的肉质应该不会好吧
