“…Hence, tail fat was 1.0 and 1.1 kg for control lambs slaughtered at 4 and 6 months, respectively, vs. 0.2 kg for docked lambs from both groups (Atti et al 1990). This was the case of other fat tail breeds but with higher values, 1 vs. 0.6 kg for Karakul (Shelton et al 1991) and 3.1 vs. 1.1 kg for Norduz lambs (Bingöl et al 2006). Carcass without tail contained the same proportion of fat for non-weaned Barbarine lambs at 4 months.…”

“…In contrast, Moharrery (2007) reported that weight gains in docked lambs of the Badghisian breed were significantly higher than the control ones. The dressing percentages were not affected by the docking for Barbarine and Norduz (Bingöl et al 2006) breeds; however, Marai et al (1987) showed higher values for docked Ossimi lambs than control ones.…”

“…Docked Barbarine lambs showed better pre-weaning growth than control ones; in post-weaning phase, docking had no significant effect on live weight gains (Shelton et al 1991;Bingöl et al 2006). In contrast, Moharrery (2007) reported that weight gains in docked lambs of the Badghisian breed were significantly higher than the control ones.…”

This review summarises the main factors that influence meat production and quality in fat-tailed Barbarine (FTB) lambs. As a general feature, FTB lamb's growth is moderate, and the average daily gain ranges between 100 and 350 g. The carcass being relatively fatty, carcass fat content varies from 10% to 32%; white fat and rose meat are often dominant in these carcasses. The meat fatty acid profile of this fat-tailed breed is similar to that of thin-tailed ones, with a prevalence of palmitic, stearic and oleic acids. The order of dissected adipose tissues accumulation, estimated by allometry coefficients, is in agreement with observations in thin-tailed sheep. However, tail fat allometry coefficient is closer to kidney fat values rather than to the subcutaneous one. Concerning effects of feed level, growth of FTB lambs fed silage is higher than those fed oat hay. With moderate concentrate supply, FTB lambs' growth is more pronounced on pasture diet than on the feedlot (FL) diet. Furthermore, at similar slaughter weights, carcasses of lambs fed pasture diet have less tail and carcass fat than those from lambs fed FL diet (5% and 18% vs. 9% and 24% for grazing and FL lambs, respectively). No difference in fat colour, fat firmness or cooked meat flavour is observed between carcasses obtained at different slaughtering weight (i.e. from 25 to 35 kg). The tail docking of FTB improved lambs' growth particularly before weaning. Its effect on carcass composition and fat proportion depends on stage of slaughtering and type of fattening diet. For suckled lambs (4 months), the docking resulted in the lower carcass fat weight (and proportion), while for fattened lambs, carcass composition was similar for all types of lambs. Overall, FTB lambs always grow slower than Noire de Thibar lambs. This is particularly pronounced during the fattening phase. Then, for FTB breed, the possibilities to obtain heavy carcasses are at risks of fat accumulation, 22.8% vs. 14.4% for FTB and Noire de Thibar thin-tailed lambs, respectively. However, the main advantage of FTB breed is that adults are well adapted to food scarcity and may produce lambs even under harsh conditions.

“…Docked lambs had slightly higher MLD areas than control lamps (P>0.05). There were insignificant differences in fat thickness over MLD area (Bingöl et al 2006). Carcass fragments and fat depth at 12th rib showed significant difference (P<0.05) between carcasses of docking and control, Badghisian lambs (Moharrery 2007).…”

The purpose of this study is to survey the literature pertinent to some morphological traits which are related with the production and reproduction of fat-tailed sheep breeds. The fat-tailed breeds were identified according to Food and Agriculture Organization databases. Articles referring to all these sheep breeds were evaluated. The morphology of udders and their measurable variables were collected and described. The particularities of pelt and fleece features which are important from an economic point of view were summarized. Linear, planar, and spatial parameters of body, slaughter, and carcass factors were compared at various ages of breeding. Testicular dimensions and semen characteristics were recorded. Their relationships with productive and reproductive performance were discussed. The pattern of ovarian follicle development and the involution of the genital tract were assessed from the anatomical point of view in normal and untreated animals. The data presented here provide useful baseline information on the normal morphological aspects which are important in the animal production of these breeds.

“…The fat-tailed Akkaraman sheep, reared in Central and Eastern Anatolia, have adapted well to harsh environmental conditions and are resistant to unfavourable management conditions, poor feeding, and diseases. Approximately 87% of the sheep population in Turkey consist of the fat-tailed breeds mainly Akkaraman, which is considered valuable owing to its productivity 20,21 . In order to meet the increased domestic demand for this breed, it is important that its productive performance is increased and the spread of diseases is prevented.…”

SummaryThis study was designed to examine the eff ect of birth weight, gender, birth type, lambing season, and dam parity and health status on lamb morbidity and mortality during the neonatal (first four weeks of life) and post-neonatal (first 5-12 weeks of life) periods in lambs born in two fl ocks in the 2009 lambing season in Kars, Turkey. EPI INFO 6 was used to determine diff erences in morbidity or mortality rates and risk according to risk factors including birth weights, genders, type of birth, lambing seasons, and parity and health of dams. The significance level was set at P<0.05 for all comparisons. The neonatal morbidity and mortality rates (48% and 33.3%, respectively) and risk of the lambs in the low birth weight group were significantly higher than those of the lambs in the medium birth weight (18.9%, X 2 =10.4, OR=3.9 for morbidity and 1.6%, X 2 =32.5, OR=30, for mortality) and high birth weight (9.8%, X 2 =26.9, OR=8.5 for morbidity and 1.2%, X 2 =46.5, OR=42.7 for mortality) groups (P<0.01 and P<0.001, respectively). The neonatal mortality rate and risk of lambs born in the winter season (9.2%) were significantly (P<0.01) higher than those of lambs born in the spring season (1.8%, X 2 =9.6 and OR=5.5). Lambs born to primiparous ewes had a neonatal morbidity rate (29.6%) and risk significantly higher than those of ewes at second parity (13.9%, X 2 =6.4, OR=2.6) and third parity (11.1%, X 2 =7.8, OR=3.3) (P<0.05 and P<0.01, respectively). Similarly, lambs born to primiparous ewes had a neonatal mortality rate (14.8%) and risk significantly higher than those of ewes at second parity (2.9%, X 2 =9.3, O=5.7), third parity (0%, X 2 =14.1) and ≥4 parity (2.4%, X 2 =4.2, OR=6.9) (P<0.001, P<0.001 and P<0.05, respectively). Lambs born to ill ewes had a neonatal morbidity rate (64.7%) and risk significantly higher (P<0.001) than those of lambs born to healthy ewes (13.8%, X 2 =30.38, OR=11.4). In the present study, it was concluded that the most significant risk factors for lamb morbidity and mortality were season of birth, parity, birth weight and health status of dams. Therefore, timely implemented health and management measures targeting these factors are required to reduce disease and death. .2, OR=6.9) doğumunu yapan annelerden doğan kuzulara göre önemli seviyede (sırasıyla P<0.001, P<0.001 ve P<0.05) yüksek bulundu. Herhangi bir hastalığa maruz kalan annelerden doğan kuzuların neonatal hastalanma oranı (%64.7) ve riski sağlıklı olan annelerden doğan kuzulara göre (%13.8, X 2 =30.38, OR=11.4) önemli seviyede (P<0.001) yüksek bulundu. Bu çalışmada kuzu hastalık ve ölümleri için en önemli risk faktörlerinin doğum sezonu, anne doğum sayısı, doğum ağırlığı ve annenin sağlık durumunun olduğu sonucuna varılmıştır. Bu nedenle, bu faktörler üzerine odaklanarak zamanında sağlık ve sevk-idare önlemlerinin sağlanması kuzu hastalık ve ölüm oranlarını azaltmak için gereklidir.
