“…Furthermore, short-tailed breeds have smaller rumens and a shorter intestine. Therefore, our results support the observation that the significant differences in weights of GIT organs owing to breed of lamb are correct (Steinheim et al, 2003;Ribeiro et al, 2009;Ríos et al, 2011) and are consistent with results on TM, AK and MK breeds in a study by Teke & Ünal (2009) and results on KY breed in a study by Yıldırım et al (unpublished data). Two of the breeds (KY and KV) have light long tails; one (TM) was a heavier crossbred with a long fat tail; and the other three breeds (AK, MK and AW) had moderate body weights and fat tails.…”

A study was conducted, first, to compare the gastrointestinal tract (GIT), reticulo-rumens and intestinal capacities (relative to body weight) of ram lambs from six Turkish sheep breeds: Turkish Merino (TM, Anatolia Merino), Akkaraman (AK), Kıvırcık (KV), Awassi (AW), Karayaka (KY) and Morkaraman (MK), and second, to examine the influence of sheep breed on the pH of the digesta in the various segments (rumen, jejunum and caecum) of the GIT. Six ram lambs from each breed were slaughtered at 40.2 ± 0.80 kg liveweight. Lambs from the AK breed had a heavier GIT weight than the AW, KY or MK breeds. The weight of the full stomach was higher in AK lambs compared with the other lambs, except for KV lambs, while the relative weight of the empty stomachs was heavier in MK ram lambs than in TM, AW and KY lambs. The AK lambs had the highest relative empty intestinal weight. The relative weight of empty intestines was heavier in KV lambs than in KY lambs. The pH of the rumen content was higher in TM and AK lambs compared with KY and MK lambs, while the pH of the caecum content of KV lambs was higher than those of KY and MK lambs. In conclusion, significant differences were found among the six breeds in terms of some variables that were studied, although a higher proportional GIT weight in the fat-tail breeds such as the MK, AK and AW was not reflected in all components or in the pH of the GIT content. ______________________________________________________________________________________ Keywords: Native sheep breed, digestive system, rumen, small and large intestine, pH value # Corresponding

“…Similar to current findings, Teke and Ünal (2009) also reported insignificant effects of SWs on skin percentages. However, Perez et al (2007), and Yakan and Ünal (2010) contrarily indicated the significant effects of SWs on skin percentages.…”

The present study was conducted to investigate the carcass traits of Karayaka lambs slaughtered at different slaughter weights (SWs) and to find out optimum SWs. Male Karayaka lambs with 20 kg live weight (n=30) constituted the animal material of the study. Lambs were randomly divided into five SW groups; 30 (GI; n=6), 35 (GII; n=6), 40 (GIII; n=6); 45 (GIV; n=6) and 50 (GV; n=6) kg. Lamb fattening feed (concentrate feed, ad libitum) and forage (lentil straw, 100g/lamb/day) were used as the feed material. Lambs were sent to slaughter at target SWs. Following the slaughter, non-carcass components, tailless hot and cold carcass weights were taken. Carcasses were separated into six sections as leg, foreleg, back, loin, neck and others. Physical dissection was performed to investigate carcass composition. Only the differences in carcass dressing and skin percentages of slaughter groups were not found to be significant. Increasing carcass fat percentages and decreasing carcass lean and bone percentages were observed with increasing SWs. Considering the consumer preferences, current findings revealed that Karayaka lambs should be sent to slaughter at weights between 30-35 kg. However, considering the red meat deficit of the country, current market conditions and producer preferences, the optimum SW for Karayaka lambs were recommended to be between 40-45 kg.

“…It has also been reported that dressing percentage increases with lambs' body weights (5,10). Dressing percentages are calculated based on slaughter weight or empty body weight in studies of carcass characters (5,15,16). In the present study, the cold dressing percentage was calculated based on empty body weight (36.400 kg).…”

The aim of this study was to determine the slaughter and carcass characteristics of Herik lambs finished under intensive husbandry conditions. Twenty single male lambs, ten of which had long, semifat tails and ten of which had short, round, and fat tails, all with an average live weight of 20 kg, were used in the study. Concentrate feed and fresh water were given ad libitum and alfalfa hay as forage was given in the amount of 300 g/lamb per day. The lambs were slaughtered when they reached a final weight of 42 kg. The average hot and cold dressing percentages, based on empty body weight (36.400 kg) of Herik carcasses, were 52.56% and 51.74%, respectively. In this study, Herik lamb carcasses had measurements similar to other indigenous Turkish sheep genotypes, except for the carcasses of the Bafra breed. The carcass components of Herik male lambs, except for the foreleg, are similar to other indigenous breeds. Consequently, Herik lambs might be considered as an indigenous genetic source for meat production under the intensive fattening system.
