The aim of this study was to determine the fattening and carcass characteristics of Meriz and goat kids raised in either intensive or pasture conditions. Twelve intact weaned male kids from each of Meriz and goat were weighed and blocked into three groups according to different feeding systems for 90 days. The 1 group was given ad libitum concentrate mixture (intensive), the 2 was freely grazed on pasture for 45 days and then transferred to having ad libitum concentrate for 45 days (Semi-intensive), the 3 one was freely grazed on pasture (extensive). At the end of the experiment, all kids were weighed, slaughtered and the weight of their carcass was recorded. Daily gain in weight averaged 0.06±0.008 kg, the difference between breeds was not significant. Kids raised intensively surpassed significantly (p<0.05) kids on semi-intensive and on pasture (0.10, 0.06 and 0.02 kg /day) respectively. Also breed has no significant effect on carcass and edible and non-edible organs weight or percentages (except the weight of pelt and the percentage of pelt and feet). Intensively and semi-intensively raised kids had significantly (p<0.01) higher carcasses, dressing percentages, larger eye muscle area and thicker of fat thickness than those raised on pasture. INTRODUCTION Small ruminant animal husbandry is the most important living source for people inhabiting in regions not suitable for crop cultivation and cattle production. In addition, goat are well adapted to the environmental and limited feed and utilized marginal land to produce high protein product (Kadim et al., 2003). The native goat with a population of 1.6 million head (FAO, 2000) is an important livestock species in Iraq and raised primarily for milk and meat which are consumed in most regions of Iraq particularly in Kurdistan. Also there is a world wide tendency for rapid increase in demand for goat meat (Stankov et al., 2002) due to several reasons including the desire for leaner meat by consumer (Potchoiba et al., 1990), a good source of desirable fatty acids (Banskalieva et al., 2000) and reducing the risk of cardiovascular disease (Stankov et al., 2002). It is well known that the most significant variable cost in any livestock operation is the feed cost. However, Daskiran et al.,(2006) concluded that pasture group kids had similar slaughter and carcass characteristics values as intensively ones. Meriz goat is found in Iraqi Kurdistan region and raised primarily for its fine hair (Alkass and Juma, 2005).However, information related to the potential of this breed as well as native goat for meat production is scare, therefore the aim of the present study is to establishment of their yield capacity and for the evaluation as a genetic resource, together with the effect of feeding system on fattening and carcass traits. Received 23/2/2009 accepted 30 / 9 /2009 Mesopotamia J. of Agric. (ISSN 1815 – 316 X) Vol. (38) No. (2) 2010 MATERIALS AND METHODS This experiment was conducted in the animal farm, College of Agriculture, University of Duhok when a total of 12 weaned male kids (3 months old) from each of native goat and Meriz obtained from commercial flock were used. After an adaptation period for 7 days, the kids from both breeds were weighed and assigned to 3 groups according to different feeding systems for a period of 90 days. The first group (intensive) was given ad libitum concentrate mixture (Table 1). The second group of kids was freely grazed at commercial flock by the shepherd for 45 days and then transferred to have ad libitum concentrate mixture for 45 days. The third group of kids was freely grazed on pasture (Little cherry, Oriental Hawthern, Valonia Oak, Kochi Thyme, Mediterrance Stinkbush and Meikle Shifshen) by the shepherd for all experimental duration. Drinking water was supplied ad libitum during the experimental period. All kids were weighed biweekly. Group one and two from each of goat and Meriz were kept in separate pens and fed on group basis. Concentrate was offered daily at 9.00 a.m after quantitifying the refusal of the previous day. Table (1): Ingredient and chemical composition of diet.
