- W1513054772 abstract "Studies of environmental factors affecting sheep production are influenced by the genetic variation that exists between animals. Recent technological advances in embryo splitting have increased the ability to produce sufficient identical twins for experimentation so it is now possible to exploit the uniformity that exists between genetically identical twins. Hancock (1951) published a series of papers on the similarity of identical twins in cattle, however, no results could be found for sheep. This paper reports the efficiency of the use of identical twins in wool sheep experiments. Thirty-five pairs of identical twins were produced over 2 years by splitting embryos collected at day 6 of pregnancy and placing each clone in a different recipient ewe. DNA testing has confirmed that the 35 pairs were identical. A wide range of fleece and body weight traits were measured at hogget age. The data were adjusted for the known environmental factors, ie birth year, sex of the lambs and age of the recipient dam and the intraclass correlation between members of a pair estimated. Efficiency was calculated according to the method of Biggers (1986) as defined in Table 1. The results presented in Table 1 indicate that 1 pair of identical twins can replace between 10 and 50 randomly selected animals in experiments without loss of statistical efficiency. Many investigations, however, involve the comparison of more than 2 treatments. Using a randomised block design, twins will allow the comparison of only 2 treatments. Biggers (1986) shows how these figures can be used to determine the most desirable experimental design where more than 2 treatments are involved." @default.
