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.

改公斤为市斤，这个数据还是比较可能的

看来质疑本文数据的网友不少，尤其对于绵羊羔的初生重。其实看待生物界的各种现象，不要用常态的眼光，更不要以自己看到过的为标准。本文中的数据是真实的。据国外文献报导，绵羊羔的初生重变化范围为3.5 到20 磅（1.59-9.08公斤），其实所指的最大值个体就是本文中的最大初生重羔羊。如果大家还不相信这个数据。我可引用美国农业部农业研究网页上的资料，地址为：http://www.ars.usda.gov/research/publications/publications.htm?seq_no_115=235943。文章的题目是：“Does breed of ram affect ewe and lamb productivity? ”发表于2009年。只引用其中的一段话：“ Lambs with birth weights that were 0.45, 0.91, or 1.36 kg (i.e., 1, 2, or 3 lb) less than the flock average of 5.2 kg (i.e., 11.5 lb) had 2.5-, 7-, and 25-fold greater risks of dying. observed mean of 5.2 kg to the maximum observed value of approximately 8.2 kg (i.e., 18 lb) had essentially no effect on lamb survival. ”可见研究中的最大个体初生重为8.2 kg 。我们在国内看到的绵羊羔初生重一般为3-4公斤，因而看到本文的数据会大吃一惊，这也是正常的。
