“…In the current study, the animal background and feeding regimens were derived from the studies by Kader Esen et al [15], Kader Esen and Elmaci [18], and Kader Esen et al [19,20]. We studied 202 later-born lambs from five different meat-type breeds [15 Males (M) and 36 Females (F) of Kıvırcık (K), 14 M and 33 F of Karacabey Merino (KM), 14 M and 14 F of Ramlıç (R), 15 M and 34 F German Black-Head Mutton × Kıvırcık (GBK), 11 M and 16 F of Hampshire Down × Merino crossbreed (HM)] whose mean weaning age was 90.5 ± 5.7 days (mean ± SD).…”

This study examined the relationship between GHE5 polymorphisms and growth and carcass characteristics of meat-type sheep breeds reared in Turkey. A total of 202 lambs were tested, consisting of five breeds. By SSCP analysis and nucleotide sequencing, 14 nucleotide changes (12 substitutions and two deletions) were identified in four variants of GHE5. In the coding region of GHE5, five substitutions occur, including c.1588C>Y(C/T) (Ala160Val), c.1603A>M(A/C), c.1604G>S(G/C) (Lys165Thr), c.1606A>W(A/T) (Gln166Leu), and c.1664C>Y(C/T). P3 female and P1 male lambs had the highest rump height at weaning, whereas P3 females and P2 males had the highest chest depth (p < 0.05). At yearling, P1 variant lambs have longer body length (BL; p < 0.05), wider leg circumferences, and thinner cannon bone perimeter (CBP) (p > 0.01), in contrast to P2 variant lambs, which have a shorter BL and thicker CBP. Furthermore, P2 had a greater percentage of neck, shoulder, and leg, P1 had a greater percentage of loin, and P3 had a greater percentage of rack, but there was no significant difference between them. A marker-assisted selection approach can be used to improve sheep carcass quality traits by taking advantage of the nucleotide substitutions found on GHE5 and the detected differences between variants.

“…Contrary to this, other studies found that LW is correlated with different body measurements depending on the sex of the lambs [ 23 ]. WH and BL are other body measurements that have been found to be highly correlated with LW [ 30 , 31 ].…”

The aim of this study was to describe the morphology and estimate live weight from body measurements of Socorro Island Merino lambs. A group of Socorro Island Merino lambs was recorded from birth to year for live weight, rump width, rump length, withers height, body length, cannon bone perimeter, and chest girth, width, and depth. The effect of the lamb type on body measurements and live weight was analyzed using ANOVA, Pearson’s correlation analysis was performed to estimate the relationship between body measurements and live weight, multiple linear regressions were fitted to obtain prediction equations of live weight from the body measurements and finally, chest girth was used to generate prediction equations using linear and exponential models. At birth and at year, differences were observed in body measurements, especially those related to the thoracic region, with crossbred males showing the highest values. Live weight was correlated with almost all the body measurements, with the highest coefficients observed with chest girth, chest width, and chest depth. Live weight can be accurately predicted from multiple regression equations using several body measurements, but using only chest girth (CG) as a predictor, the exponential equation W0–365 = 0.9142 exp(0.0462 CG) showed the best accuracy.
