“…In the current study, results indicated that the overall mean of animal shoulder weight was lower than in Rambouillet lambs (2.300±0.28 kg, Peraza-Mercado et al, 2010), Turkish Tuj lambs docked (2.59±0.07 kg, Tilki et al, 2010) and Chilote (4.55±1.19 kg, Ramírez-Retamal et al, 2013). But it was higher than that of Karakaş male lambs (0.49±0.03 kg, Gökdal et al, 2003) and Turkish Tuj docked lambs (0.44±0.02 kg, Bing¨ol et al, 2005).…”

Feeding on white or black whole barley grain and fattening period's effect on the body weight and measurements, as well as carcass quality of Karadi male lambs was investigated in this study. A total of sixty Karadi male lambs aged six month-old was randomly allocated to two feeding systems (white or black barley grain) for four periods of experimental fattening trial (each period was one month). Body weights as well as total body gain for lambs fed white barley were significantly (P<0.05) higher than lambs fed black barley during experimental periods. Feeding white barley significantly (P<0.05) increased body length at eight-month (second period), nine month (third period) and final weight (fourth period) compared to black barley. Moreover, height at withers and heart girth showed significant differences at the final period (age of 10 th months). Result showed a high interaction between fattening periods and feeding regimes on the length of body, wither height and the girth of heart. This may indicate that lambs at different experimental periods responded differently to type of barley. It is concluded that body weights, total body gain and body measurements for lambs fed white barley were significantly higher than lambs fed black barley.

“…In actual production systems, tail docking and removal in rams seemed to aid the prevention of blowfly strike (Shutt et al, 1987), and it is generally considered good flock management (Kent et al, 1995). Additionally, considering the preferences of consumers and processors for animals with less fat, docking can reduce the total carcass fat of fat-tailed sheep (Muammer et al, 2010). Lanzhou fat-tailed sheep are located primarily in Lanzhou City, Gansu Province.…”

“…There are numerous studies on the effects of tail docking on the production, reproductive traits, and physiological functions of fat-tailed sheep, and several studies examine the genes that effect meat traits, fatty acid composition of muscles, and carcass traits (Marai et al, 1987;Al Jassim et al, 2002;Sarvar et al, 2009;Muammer TK et al, 2010;Sun et al, 2014). However, research evaluating the impact of tail docking on the expression of genes related to lipid metabolism has not been widely reported.…”

ABSTRACT. To evaluate stearoyl-CoA desaturase (SCD), hormonesensitive lipase (HSL), lipoprotein lipase (LPL), and peroxisome proliferator-activated receptor (PPARγ) expression in Lanzhou fat-tailed sheep (with and without docked tails), 18 rams were randomly divided into two equal groups (docked group, LT; control group, LC). These data were also used to increase the understanding of sheep fat deposition and metabolism. All animals were harvested at the age of 18 months, and expression was determined for 10 tissues. The results indicated that the fat weight of each tissue in LT was higher than in LC (P < 0.05). SCD expression in semitendinosus, omentum majus fat (OF), subcutaneous fat, kidney fat (KF), and subcutaneous rump fat was higher in LT than in LC rams (P < 0.05). Trends (P < 0.10) associated with higher HSL expression of LC in comparison to that of LT rams in intestinal fat, OF, and KF tissues were detected. Numerically, LPL expression was the highest in KF, OF, and kidney tissues, but there were few differences (P > 0.10). PPARγ expression was greater in LT than in LC rams in liver tissues (P < 0.05), but there were few differences in other tissues. No significant differences were found with regard to the regression analysis of expression and adipose tissue weights, but the two indices exhibited the same trend. The results indicated that changes in fatty deposits may be due to the common control of docking management and the minor effects associated with the regulation of SCD, HSL, LPL, and PPARγ expression.

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.
