“…In ultrasound scanning, all tissues above the muscle (including subcutaneous fat and skin) were considered as fats (Theriault et al, 2009). Different from our results, the values of eye muscle area and back fat thickness were reported to be 11.71–14.40 cm 2 and 3.68–7.94 mm, respectively, for the Akkaraman lambs with 40–45 kg live weight (Sahin & Akmaz, 2002; Tufan & Akmaz, 2001). These differences might be attributed to different breeds of animal, age, sex, parts of the body, operator experience, levels of management and nutrition, and ultrasound devices.…”

This study aimed to investigate the performance of least-squares support vector machines to predict carcass characteristics in Tan sheep using noninvasive in vivo measurements. A total of 80 six-month-old Tan sheep (37 rams and 43 ewes) were examined. Back fat thickness and eye muscle area between the 12th and 13th ribs were measured using real-time ultrasound in live Tan sheep. All carcasses were dissected to hind leg, longissimus dorsi muscle, lean meat, fat, and bone to determine carcass composition. Multiple linear regression (MLR), partial least squares regression (PLSR), and least-squares support vector machines (LSSVM) were applied to correlate the live Tan sheep characteristics with carcass composition. The results showed that the LSSVM model had a better efficacy for estimating carcass weight, longissimus dorsi muscle weight, lean meat weight, fat weight, lean meat, and fat percentage in live lambs (R = 0.94, RMSE = 0.62; R = 0.73, RMSE = 0.02; R = 0.86, RMSE = 0.47; R = 0.78, RMSE = 0.63; R = 0.73, RMSE = 0.02; R = 0.65, RMSE = 0.03, respectively). LSSVM algorithm was a potential alternative to the conventional MLR method. The results demonstrated that LSSVM model might have great potential to be applied to the evaluation of sheep with superior carcass traits by combining with real-time ultrasound technology.

“…In the present study, averages of 149.00, 37.68, and 72.80 cm, respectively, indicated no influence of the level of concentrate on bone development. Ulutaş et al (2021) reported an average carcass length and carcass width of Turkish Anatolian buffaloes close to that found in the present study.…”

“…The carcass weights in the present study can be justified by the linear growth of the slaughter weight of the animals (Ulutaş et al, 2021). In the present study, the cold carcass weight ranged from 124 kg to 159 kg, a value close to that reported by Masucci et al (2016) when evaluating dietary levels of silage in Mediterranean buffalo.…”

“…Due to the seasonality of forage production in some regions, producers may need to use concentrated feeds to supplement their herds (Contò et al, 2022). There is a need to encourage the slaughter of young animals and the characterization of their meat to standardise and create a product identity, such that buffalo meat commercialization can be improved (Li et al, 2018;Ulutaş et al, 2021). The quality and quantity of buffalo meat depends upon several factors, such as breed, age, feeding intensity, management system, and environmental conditions (Awan et al, 2014;Naveena & Kiran, 2014).…”

The objective of this study was to evaluate the influence of diets with increasing concentrate levels on performance, carcass characteristics, and meat quality of Murrah buffaloes in feedlot. Twenty-four animals, with an initial body weight of 240 ± 50.5 kg and mean age of 9 months, were distributed to four treatments: 20%, 40%, 60% and 80% concentrate. After 114 days, the animals were weighed, slaughtered, and meat quality and performance data were submitted to analysis of variance and regression. The dry matter intake and average daily gain increased linearly. The final body, hot carcass, and cold carcass weights responded linearly to increases in concentrate level. The subcutaneous fat thickness, protein, and ether extract of meat increased linearly with an increase in concentrate level. The colour parameters, cooking losses, and shear force of the meat were not affected by increasing the concentrate. The inclusion of concentrate in feedlot diets increases performance, characteristics of carcass, and meat quality of Murrah buffalo in a feedlot.

Akkaraman sheep, which is resistant to harsh climatic conditions, is one of the local fat tail sheep breeds.…”

Conducted within the National Sheep and Goat Breeding “subproject: Akkaraman Sheep Breeding Project under farmer conditions in Nigde’s Bor district” between 2018 and 2022, the current study evaluated the reproductive characteristics of ewes as well as the livability and growth traits of lambs. This study investigated some ‘reproductive traits’ of an average of 6000 ewes per year and ‘growth performance and ‘survival traits’ of a total of 30051 head lambs. The birth weight (LBW), 60th-day body weight (BW60), 120th-day body weight (BW120), and 120th-day body weight gain (BWG120) of Akkaraman lambs during the study periods were 4.14±0.19 kg, 18.58±0.03 kg, 31.31±0.02 kg, and 246±2.23 g/lamb/day, respectively. In the study, among the factors affecting the growth characteristics of Akkaraman lambs, only the effect of gender on BWG120 and birth type on BW120 was found to be insignificant. In contrast, the other factors were found to be found to be statistically significant. In the study, it was determined that the number of lambs per Akkaraman ewe giving birth between 2018-2022 varied between 1.03-1.10. The highest livability in Akkaraman lambs was determined in 2018 (96.61%) and the lowest in 2020 (83.21%). As a result, it was found that liveability in Akkaraman lambs was dependent on birth year, the age of the ewe, gender, and birth type.
