“…In addition, the percentage of intramuscular fat in fat-tailed sheep is low; thus, fat-tailed sheep can provide a low-fat protein source. In contrast, short-tailed sheep have higher stores of intramuscular fat (Kashan et al, 2005). Therefore, understanding the mechanism of fat metabolism and deposition would be useful in improving the quality of meat and for human health.…”

ABSTRACT. Research on gene regulation has been made possible with the help of RNA sequencing applications such as RNA-Seq technology for high-throughput sequencing platforms. Recent studies have explored the transcriptomes from different tissues of domestic animals using RNA-Seq technology, but little research has been done to study the transcriptomes of breeds of sheep having different adipose tissue deposition mechanisms, such as Mongolian and Lanzhou fattailed sheep. In this study, Mongolian and Lanzhou fat-tailed sheep were selected as experimental breeds, and six libraries (three libraries per breed) were constructed. A total of 286 Mb of high-quality reads was obtained, and three-quarters of the reads were mapped to the reference genome per library. In addition, there were 16,257, 16,186, 16,254, 16,827, 16,437, and 15,761 known reference genes in the six constructed libraries (LCL1, LCL2, LCL3, MCL1, MCL2, and MCL3, respectively). Seven genes were differentially expressed: four were upregulated and three were downregulated in liver tissue between the MCL and LCL groups; 65,303, 65,442, 63,426, 76,267, 69,853, and 57,439 potential cSNPs were detected in the six libraries, respectively, with the G/R substitution occurring most commonly. There were 24,239, 22,283, 22,457, 26,635, 27,093, and 18,700 alternate splicing (AS) events in the six libraries. Intron retention was the most common AS event, followed by alternative 3' splice sites. These results indicate that there are many differences in the liver transcriptomes of Mongolian and Lanzhou fat-tailed sheep breeds. Such results may provide fundamental information for further research on defining the sheep genome.

“…Yardımcı et al [13] reported that the tail fat, subcutaneous fat and intermuscular fat percentages were 15.29%, 10.2% and 4.88% in White Karaman sheep of 41.6 kg body weight. Kashan et al [2] reported that in Chaal (fat tailed), Zandi (fat tailed), Zel x Chaal (semi-fat tailed) and Zel x Zandi (semi-fat tailed) sheep, tail fat percentages were 13.6, 15.8, 7.2 and 7.5%, respectively, that subcutaneous fat percentages were 13.8, 14.9, 17.6 and 18.5%, respectively, and that intermuscular fat percentages were 5.7, 8.1, 9.3 and 9.4%, respectively. Kyanzad [28] reported that as the tail fat percentage decreased, the subcutaneous fat and intermuscular fat percentage increased in thin tailed x fat tailed crossbred lambs.…”

Citation of This ArticleTeke B, Uğurlu M, Akdağ F, Ekiz B: The relationship between body dimensions and fat deposits in Herik lambs. Kafkas Univ Vet Fak Derg, 23, 117-122, 2017. DOI: 10.9775/kvfd.2016 AbstractThe aim of this research was to determine the relationships between some body measurements and fat deposits in the Herik lamb, reared in the central Black Sea Region of Turkey. In this study, data on 20 single-born male Herik lambs, namely 10 with short, round, fat tail, and 10 with long, semi-fat tails, were used. They were finished for an average of 105 days under intensive management after weaning and slaughtered at an average body weight of 40 kg. Several body measurements were taken before slaughter. Carcasses were cut into sections which were separated into meat, bone and fat. Weights of tail, carcass and non-carcass fat were recorded and used in the calculation of the total body fat weight. The highest correlation coefficient was between tail fat weight and the upper tail circumference (r= 0.937, P<0.01), and the lowest was between the fat tail weight and tail length (r=0.059). The upper and lower tail circumferences explained 88% of total variation in the tail weight, and 71% of total variation in total body fat, respectively. In conclusion, lower and upper tail circumference can be used to predict fat tail weight, as well as total body fat, in Herik lambs. More detailed studies are needed for the determination of the relationship between body measurements and fat deposits and to improve the carcass characteristics of Herik lambs. Keywords: Body measurement, Carcass, Fat, Herik, Lamb, Meat Herik Kuzularında Bazı Kuyruk ve Beden Ölçüleri ile Yağ Depoları Arasındaki İlişki ÖzetBu araştırmanın amacı, Türkiye'de Orta Karadeniz Bölgesinde yetiştirilen Herik kuzularında bazı beden ölçüleri ile yağ depoları arasındaki ilişkiyi belirmekti. Bu çalışmada 10 baş kısa yuvarlak yağlı kuyruklu ve 10 baş uzun yarım yağlı kuyruklu kuzu olmak üzere 20 erkek tekiz doğmuş Herik kuzusu kullanıldı. Kuzular sütten kesimden sonra ortalama 105 gün entansif koşullarda beslendi ve ortalama 40 kg da kesildi. Kesimden önce bazı beden ölçüleri alındı. Karkaslar parçalara ayrıldı. Karkas parçaları et, kemik ve yağa ayrıldı. Kuyruk, karkas ve karkasa ait olmayan yağlar tartıldı ve toplam beden yağ ağırlığı belirlendi. En yüksek korelasyon kuyruk yağı ağırlığı ile kuyruk kökü çevresi arasında (r=0.937, P<0.01), en düşük korelasyon ise kuyruk yağı ağırlığı ile kuyruk uzunluğu arasında bulundu (r=0.059). Kuyruk kökü ve en geniş kuyruk çevresi, kuyruk yağı ağırlığındaki varyasyonun %88'ini, toplam beden yağı ağırlığındaki varyasyonun ise %71'ini açıkladı. Sonuç olarak, Herik kuzularında kuyruk kökü ve en geniş yerindeki kuyruk çevresi hem kuyruk yağı ağırlığını hem de toplam beden yağı ağırlığını tahmin etmede kullanılabilir. Herik kuzularında kuyruk ölçüleri ile yağ depoları arasındaki ilişkiyi belirlemek ve Herik kuzularının karkas özelliklerini geliştirmek için daha fazla çalışma yapılmalıdır.

Adipose tissue is found in various parts of the sheep body, some of which are the subcutaneous layer under the skin, around the kidneys, within the abdominal cavity, and tail. The tail fat is the most typical deposited fat, especially in the several Mongolian sheep breed, such as Sunite Sheep (SS), Wuzhumuqin Sheep, and Wuranke Sheep, which are several fat-tailed sheep species in China. Among them, SS is the
