    Carcass and meat quality of Gokceada Goat kids reared under extensive and semi-intensive production systems
    (Elsevier Sci Ltd, 2014) Ozcan, Mustafa; Yalcintan, Hulya; Tölü, Cemil; Ekiz, Bulent; Yilmaz, Alper; Savaş, Türker
    The aim was to compare the carcass and meat quality characteristics of male and female Gokceada Goat kids produced in extensive (n = 20) and semi-intensive (n = 20) systems. In extensive and semi-intensive produced kids pre-slaughter weights were 17.44 and 12.51 kg; cold carcass weights were 8.66 and 535 kg and cold dressing percentages were 54.9 and 49.28%, respectively. The effect of kid sex was not significant on hot and cold dressing percentages, back fat thickness, M. longissimus dorsi section area, carcass fatness and conformation scores, and carcass measurements, while female kids had higher omental and mesenteric fat and kidney knob and channel fat percentages than male kids. Extensive produced kids had lower meat lightness. Panellists evaluated extensive system kids with higher scores of kid odour intensity, flavour intensity and overall acceptability. It was concluded that it would be more appropriate to use an extensive system in Gokceada Goat breeding for kid meat production. (C) 2013 Elsevier Ltd. All rights reserved.

    Carcass Characteristics and Meat Quality of Karacabey Merino lambs Reared under Triticale and Oat Pastures Compared with Stall-Fed Lambs
    (Mdpi, 2023) Oral, Hulya Hanoglu; Kecici, Pembe Dilara; Alaturk, Firat; Tölü, Cemil; Ekiz, Bulent; Gokkus, Ahmet
    Simple Summary An economical livestock production model in which all the needs of the lambs can be met and they reach the optimal slaughter weight in the shortest possible time is the primary goal of all production models. Since the production system is an important factor for carcass and meat quality, different production systems have been developed. In intensive systems with concentrates, carcasses tend to be fatter and reach optimal slaughter weight faster, whereas pasture-fed animals have a better fatty acid profile and redder colour due to higher physical activity. In our study, we investigated the effects of feeding system, birth type, gender, and birth year on the carcass and meat quality of Karacabey Merino lambs. The effects of gender and birth type on Karacabey Merino lambs showed the expected results: single-borns have more muscle tissue than multiples, males have more muscle tissue than females, and females have higher carcass fatness. In conclusion, a pasture-based feeding system is more suitable for Karacabey Merino lambs than a stall feeding system, if lean and tender meat is preferred. However, it should not be ignored that lambs fed in stalls showed better fattening performance in terms of conformation and fatness, during the same period.Abstract Fifty-eight Karacabey Merino lambs were used to study the effects of feeding system (triticale pasture, oat pasture, or stall-fed), birth type (single or multiple), gender (male or female), and birth year (2016 or 2017) on various carcass and meat quality characteristics. Stall lambs had higher conformation (CS) and fatness (FS) scores, and higher meat L* and h* values than the two pasture groups, possibly due to higher fat content, while oat pasture lambs had the most tender meat. Single-born lambs had higher CS, FS, and Longissimus thoracis muscle section area, while females had higher subcutaneous and non-carcass fat deposits than their counterparts. Both single-born lambs and 2016-born lambs had higher meat a* and C* values than their counterparts. In conclusion, a pasture-based feeding system is more suitable for Karacabey Merino lambs than a stall feeding system, if lean meat and/or meat products are preferred. However, it should not be ignored that stall-fed lambs showed a better fattening performance in terms of conformation and fatness, during the same period.

    Carcass measurements and meat quality characteristics of dairy suckling kids compared to an indigenous genotype
    (Elsevier Sci Ltd, 2010) Ekiz, Bulent; Ozcan, Mustafa; Yilmaz, Alper; Tölü, Cemil; Savas, Tuerker
    Effects of genotype on carcass measurements and meat quality were investigated by using 24 suckling kids from Turkish Saanen, Gokceada and Maltese breeds. Carcass quality characteristics of indigenous kids (Gokceada) were lower than those of dairy type (Turkish Saanen and Maltese) kids. Breed effect on ultimate meat pH, cooking loss, drip loss and Warner Bratzler shear force values were not significant. Meat samples from Turkish Saanen kids had higher redness (at 0, 1 and 24 h) and yellowness (at 24 h) values than Gokceada kids (P < 0.05). Breed had no significant effect on sensory characteristics except flavour intensity. Flavour intensity scores given to meat samples of Maltese kids were higher than those of Turkish Saanen and Gokceada kids (P < 0.01). In conclusion, dairy type breeds should be considered for meat production as well, with meat from Maltese kids potentially offering better colour and flavour intensity than that of Turkish Saanen kids.

    Genotype, production system and sex effects on fatty acid composition of meat from goat kids
    (Wiley, 2015) Ozcan, Mustafa; Demirel, Gulcan; Yakan, Akin; Ekiz, Bulent; Tölü, Cemil; Savaş, Türker
    Two trials were performed to assess the meat fatty acid profile of goat kids from different genotypes, production systems and sex. In the first trial, genotype effect was determined in 24 suckling male kids from Turkish Saanen, Maltese and Gokceada breeds. In the second trial, male and female Gokceada Goat kids were used to compare the effect of extensive and semi-intensive production systems on fatty acid composition of meat. Significant genotype effect was observed in the percentages of myristic acid (C14:0), palmitic acid (C16:0), oleic acid (C18:1 n-9), linolenic acid (C18:3 n-3), arachidonic acid (C20:4 n-6) and docosahexaenoic acid (C22:6 n-3), despite no differences on the ratios of polyunsaturated fatty acids to saturated fatty acids (PUFA/SFA) and n-6/n-3 (P>0.05). The effect of production system had also significant effects on fatty acids, but sex only influenced significantly stearic acid (C18:0), C18:1 n-9 and C18:3 n-3 fatty acids and total PUFA level and PUFA/SFA ratio. This study confirms that dairy breeds are prone to produce higher levels of unsaturated fatty acids in their muscle. Meanwhile, meat from Gokceada goat kids, which is one of the indigenous breeds in Turkey, had similar PUFA/SFA and n-6/n-3 ratios to Turkish Saanen and Maltase.
