Evaluating Texel-, Suffolk-, and Columbia-Sired Offspring: I. Prolificacy, Survival, and Preweaning Growth Traits Under a Forage-Based Lambing System

Myostatin mutation (g+6723G > A) introgression: comparative analysis of growth, slaughter, and carcass traits in Texel, Pırlak, and their crosses (F1 and BC1)

“…The birth weight, daily live weight gain, and 6-month live weight averages of myostatincarrying BC 1 lambs were higher than Texel lambs. The growth performances of the genotypes up to weaning in this study were in the range of values reported in the literature for pure Texel and crosses (McMillan et al, 1988;Wuliji et al, 1995;Freking and Leymaster, 2004;Ali et al, 2005;Khusro et al, 2005;Maxa et al, 2007;Koritiaki et al, 2013;de Vargas Junior et al, 2014;de Fatima Sieklicki et al, 2016;Armstrong et al, 2018;Çelikeloglu et al, 2022;. Genotype had an insignificant effect on weaning weight, and myostatin did not affect weaning weight either according to carrying and non-carrying lamb phenotypes.…”

“…The values related to the same traits in Texel crosses vary between 3. 04 and 5.30 kg, 170 and 267 g, 14.86 and 33.47 kg, and 50.41 and 51.40 kg, respectively (Wuliji et al, 1995;Freking and Leymaster, 2004;Ali et al, 2005;Koritiaki et al, 2013;de Vargas Junior et al, 2014;Çelikeloglu et al, 2022;Tekerli et al, 2022). Also, Çelikeloglu et al (2022) reported 6-month live weights of 34.40 and 36.91 kg for F 1 and BC 1 Texel cross lambs.…”
