The characteristics of this breed <br />are: <br />1.- Cearse weel; <br />2.-Very big, large fat-tail. <br />The animal saves part of the supernuous <br />nutrients which he receives during <br />the abudant periods and keeps them as <br />fat in its tail for more severe seasons of <br />the year. <br />Consequently, in order to ameliorate <br />the quality of the wool of the abovementioned <br />stock, an intensive cross-breeding <br />program with the use of Merino <br />rams of Central Anatolia has been under <br />app1ication since 1950. But owing <br />to the fat-tail of Karaman ewes, the <br />slender-tailed Merino rams are unabIe <br />to jump on them; and as such, it becomes <br />almost always necessary to recourse <br />to the artificiaı insemination in the framework <br />ai tbe cross-breeding program. <br />Howevet, this artificial insemination <br />turns out to be a very difficu1t as well <br />as expensive method under hard conditions <br />that prevail in most parts of <br />Anatolio <br />Sut in ’spite of the above-mentioned <br />handicaps, the first worker of our team <br />has done a more or less sııccessfuI experiment <br />on Mor Karaman ewe lambs <br />by cutting their tails at first and then <br />mating them with merina rams. Howe-. <br />’>er, sonn after the experiment same <br />questions are raised as to - <br />1. The docking of the fat-tailed Karaman <br />lams; and <br />2. the effects of docking and docking <br />methods produced on the rate of <br />growth and mating abilit)’ of Mor Kara <br />man ewes with merino ram lambs. <br />There different implements have <br />been used in the docking methods:- <br />1. Burdjzzo forcepts and a knife <br />(for cutting the taiI); <br />2. A mbber ring (elastration ring); <br />3. A string or cord (used for tying <br />the tail). <br />Docking the animals with burdizzo <br />forceps and a knife was veryeasy and <br />practicable. The tail was squeezed with <br />burdizzo forceps between the second <br />and the third node of the tail-bone, !J,nd <br />than was cut with a knife. Wouıids <br />recovered in about 8 days. <br />Application of the rubber ring was <br />easy, too. Tails that had been squeezed <br />with rubber rings, eventually broke down <br />and dropped by themselves ten or <br />fifteen days after the application of the <br />mbber ring; and wounds located in places <br />of articulations, recovered completely, <br />in about twenty-one days after the <br />application of the rubber ring. <br />The third but the worst and most <br />painful of aU the three docking methods <br />was the method where tails were tied <br />and squeezed with a cord or string, in <br />artinılation places. After the tying tails <br />97 <br />swelled and anİmals la id down, lost <br />their appetites, owing to the pain, till after <br />a fortnight when tails were separeted <br />from the body by amputation. <br />in every of the three docking methods <br />the following order was observed:- <br />i. For every method, newly-born <br />eight ewe lambs and eight ram lambs of <br />Morkaraman stock were used <br />as experiment animals. <br />2. The ewe and ram lambs used, <br />aged between one and three days; <br />3. Against 24 ram lambs and 24 <br />ewe lambs that underwent the docking <br />procedure, an equal number of male <br />and female lambs were kept as control <br />group for corİıparison purposes. <br />Rate of Growth <br />In order to find out the effects of <br />every method produced on the rate of <br />growth, lambs were weighed at an interval <br />of fifteen days, as from the date of <br />their birth, until the end of the experiment. <br />Besides, even after the animals had <br />beeome twenty-one days old, measurements <br />of different parts of their bodies <br />were taken in every fortnihgt. Weighing <br />and measurement proeedures eontinued <br />until the end of the experiment, <br />i. e. until 112 th day. <br />i. Thus, we can analyse from the <br />weight increase point of view the effects <br />of docking and docking methods on <br />the rate of growth, in this way : <br />i. with the exception of the cordappIied <br />group lambs, the average gain <br />of ewe lambs was generally less than <br />98 <br />th ose of the ram lambs, and the effects <br />of docking and docking methods 00 <br />their weight İncrease, too, were hardly <br />notieeable; they were significantly more <br />on the ram lambs, so mueh so that, by <br />various different method appIications, <br />important differences were obser vable <br />between the taiJed and the docked ones. <br />2.
