THE IMPACT OF DOCKING KARADI LAMBS ON GROWTH PERFORMANCE, CARCASS TRAITS AND BODY COMPOSITION

Twelve new born Karadi lambs were docked within 3 days of their birth using rubber-rings, and left with their mothers till weaning (2.5 months). Another 12 weaned Karadi lambs obtained from local market were left intact. Following an adaptation period of a week, the docked and intact lambs with an average initial weight of 16.83±1.522 and 19.92± 0.748kg were randomly divided into three equal groups to be slaughtered at 20, 30 and 40kg. Results revealed that overall means of daily gain in weight, dressing percentage based on slaughter and empty body weight, rib eye area and fat thickness were 0.261±0.014kg, 45.956±0.428%, 53.933±0.678%, 11.288±0.488cm2 and 2.023±0.76mm, respectively, and no significant difference exist between them except dressing percentage based on empty body weight. It appears that carcasses of intact lambs compared to docked lambs contained significantly higher lean (62.79 vs. 59.85%), lean: fat (5.319 vs. 4.142), lean: bone (2.772 vs. 2.489) and numerically lower fat (16.058 vs. 14.042%) and bone (23.172 vs. 24.096%). Also, it was noticed as slaughter weight increase, there is an increase in dressing percentage, rib eye area, fat thickness, fat content of their carcass with a lower proportion of lean and bone.

Growth performance, nutrient utilization, rumen fermentation, blood biochemistry, and carcass traits of lambs fed Atriplex nummularia L. hay-based diet supplemented with yeast or bacterial direct- fed microbial

Direct fed microbial may enhance the utilization of halophyte forages leading to improved animal growth and productivity. This study was conducted to evaluate Atriplex hay-based diet supplemented with yeast (Saccharomyces cerevisiae; SC) or bacteria (Bacillus subtilis and Lactobacillus casei; BAC) on lamb growth performance, digestibility, rumen fermentation, and carcass characteristics. Fifteen Barki lambs (90 ± 7 days of age and 18.6 ± 0.41 kg SE body weight; BW) were randomly assigned to three treatments for 120 days as follows: Control (basal diet without supplementation), SC and BAC diets, the basal diet supplemented with SC or BAC at 2 g/head/day, respectively. All lambs had similar dry matter (DM) intake, while lambs fed SC or BAC dies had higher (P < 0.05) total gain and average daily gain than those fed the control diet. Supplementation of SC or BC increased (P < 0.05) the digestibility of DM, organic matter, and acid detergent fiber, tended to decrease (P < 0.05) the urine N excretion and enhanced the N balance compared to the control. Ruminal pH, acetate, total volatile fatty acids concentrations, and bacterial protein were increased (P < 0.05), while creatinine and urea concentrations were decreased (P < 0.05) by both additives. Compared to other diets, the BAC diet reduced (P < 0.05) triglycerides, total lipids, kidney fat, and eye muscle fat. In conclusion, both additives resulted in similar positive growth performance and feed utilization, while only the BAC additive had a beneficial advantage in reducing the fat content of the carcass.

To Determine the Effect of Using a Complete Feed Containing Protected Soybean Groats in the Production of Javanese Thin-Tailed Male Sheep Carcasses

The present study aims to determine the impact of complete feed containing protected soybean meal on the production of male thin-tailed lamb carcasses. A total of 15 (23.43 ± 1.40 kg) 12 months old male Thin-Tailed Sheep (TTL) were given 3 treatments and 5 replicates in a completely randomized design. The ration consisted of complete feed and formaldehyde-protected soybean groat (PSG). The treatments includes 100% complete feed (F1), 90% complete feed + PSG 10% (F2), and 80% complete feed + PSG 20% (F3). Data were analyzed using ANOVA and differences between treatments were further tested using Duncan’s New Multiple Range Test. The results indicated that the use of PSG containing complete feed did not improve the characteristics of carcasses (weight and percentage of carcass components, half-cuts and commercial cuts of carcass, fleshing index and meat bone ratio) of male TTLs (P&gt;0.05). However, differences were found in the rib eye muscle area. The use of complete feed containing 20% PSM (F3) resulted the highest rib eye muscle area figure compared to those of F2 and F1 (35.17 vs 27.00 and 26.33; P&lt;0.05). Our study revealed that the use of complete feed containing 20% protected soybean groat resulted in higher rib eye muscle area by 25.14% compared to those containing no protected soybean groat. However, no differences in carcass characteristics were found in view of weight and percentage of carcass components, half cut and commercial carcass, fleshing index and meat bone ration in thin-tailed sheep.

Comparison of carcass and meat quality traits of the native Polish Heath lambs and the Carpathian kids

ABSTRACT The aim of the study was to compare selected parameters of carcass and meat quality including testing of volatile compounds of male lambs and kids derived from Polish native breeds (Polish Heath Sheep and Carpathian Goat). For most of the slaughter parameters, no differences were found between the two species although the meat and bones weights in the legs of kids was higher than that found for lambs. The study shows differences in the chemical composition and quality characteristics of the meat. Drip loss was lower in kid meat, indicating better water binding capacity. In contrast, the roasted meat of Carpathian kids was less tender than that of lambs. There was more dry matter and protein in the muscle of the kids; the differences between species occurred between most fatty acids. The analysis of volatile compounds showed differentiation between the evaluated meat of lambs and kids. Despite the differences in the assessment of the physico-chemical and nutritional parameters of lamb and goat meat, both types of meat can be considered are a valuable component of the diet, while high values of the organoleptic assessment indicate a good reception of both products by consumers.

Performance and carcass characteristics of lambs fed diets supplemented with different levels of Saccharomyces cerevisiae

The objective of this study was to evaluate the productive performance, apparent digestibility, and carcass and longissimus dorsi muscle characteristics of lambs fed diets supplemented with four levels of Saccharomyces cerevisiae. Thirty-two male Hampshire lambs (25.82±1.95 kg body weight) were distributed in four treatments: basal diet (20:80, forage:concentrate), and the inclusion of 0, 3, 5, and 10 g animal−1 d−1Saccharomyces cerevisiae. The variables evaluated were dry matter intake, daily weight gain, feed conversion, apparent digestibility, dorsal fat thickness, longissimus [...]

Prediction of lamb carcase C-site fat depth and GR tissue depth using a non-invasive portable microwave system versus body condition scoring

This study compared portable ultra-wide band microwave system (MiS) versus body condition score to predict C-site fat depth, GR tissue depth and eye muscle depth (EMD) in lambs. Experiment 1 assessed MiS and condition score to predict ultrasound measured C-site and EMD (n = 1549). Precision and accuracy was greatest for the MiS measurement with liveweight included in the model, with a C-site predicted RMSEP of 0.58 mm, R2 0.60 and bias of 0.021 mm and an EMD predicted RMSEP of 2.27 mm, R2 0.72 and bias of 0.088 mm. Experiment 2 (n = 900) assessed pre-slaughter MiS scanning and condition scoring to predict carcase GR tissue depth, C-site fat depth and EMD. MiS performed better than condition score for all three carcase trait predictions, regardless of the inclusion of liveweight, with the highest precision and accuracy for GR tissue depth determination with a RMSEP of 3.68 mm, R2 0.63 and bias 0.072 mm.

Grape pomace silage on growth performance, carcass, and meat quality attributes of lambs

Grape pomace is a by-product that can be ensiled and added to animal feed for a sustainable animal production. This study evaluated the effects of grape pomace silage (GPS) on the intake, performance, and carcass and meat quality of feedlot lambs. Twenty-four male lambs (21.5 ± 3.0 kg initial body weight) were distributed into pairs to four diets levels 0, 10, 20, and 30 % of GPS. The addition of grape pomace silage influenced only ether extract (EE) intake linearly without hindering consumption. The diet did not affect performance and meat quality attributes and carcass parameters, with average daily gain (ADG) of 0.235 kg d−1, feed conversion 4.299, carcass conformation 2.7, compactness index 0.25 kg cm−1, fat thickness 1.51 mm, loin eye area 13.9 cm2, pH 5.79, natural matter moisture 74.05 g 100 g−1, and crude protein (CP) 19.94 g per 100 g−1 of dry matter (DM). Grape pomace as could be used as silage in lamb diets with up to 30 % GPS, as the chemical composition of this by-product and the results indicate that GPS did not compromise performance, carcass traits, and meat quality.

Carcass and Meat Quality of Lambs from Thin-Tailed and Fat-Tailed Breeds at Five Different Slaughter Weights

Abstract In lamb production, deciding the optimal slaughter weight (SW) has great importance on product quality. The aim of the study was to determine the optimum SW for lambs from a thin-tailed breed (Kivircik) and a fat-tailed breed (Kangal Akkaraman) in order to get high-quality meat and carcass. Kivircik (n=60) and Kangal Akkaraman (n=59) lambs were allotted to five SW groups (20, 28, 36, 44 and 52 kg). In Kivircik lambs, backfat thickness and fatness score gradually increased in parallel with the increase in SW, while the increase in the tail fat and kidney knob and channel fat (KKCF) proportions were observed by up to 36 kg. In Kangal Akkaraman lambs, evident increases in fatness parameters, except tail fat proportion, were observed when the SW increased from 44 kg to 52 kg. Meat pH, Warner Bratzler shear force (WBSF) and cooking loss values were not influenced by SW in lambs of both breeds. As SW increased in Kivircik lambs, there was a significant decrease in meat lightness and an increase in yellowness. In Kangal Akkaraman breed, lambs slaughtered at 20 kg and 28 kg had higher L* values, and lower a* and C* values than those of other SW groups. In Kivircik lambs, the total PUFA proportion and the ΣPUFA/ ΣSFA ratio were lower in SW-44 and SW-52 groups than those of SW-20 and SW-28 groups. Decreases of these parameters were in SW-52 group in Kangal Akkaraman lambs. In meat samples of both breeds, SW-52 groups had a lower Σn-3 proportion and a higher Σn-6 / Σn-3 ratio than other SW groups. In Kivircik lambs, the panellists evaluated the meat of SW-20 and SW-28 groups as tender compared to those in SW-44 and SW-52 groups. In Kangal Akkaraman breed, flavour intensity in the meat of SW-52 lambs was higher than those of SW-20 and SW-28 groups. Results of the study indicate that slaughtering of lambs at 20 kg and 28 kg in both breeds provided better meat quality but caused lower carcass weight. Therefore, slaughtering Kivircik and Kangal Akkaraman lambs at 20 kg and 28 kg live weight might be recommended especially to farmers, who aim to obtain high-quality lamb meat. In this case, it should not be ignored that the amount of meat produced will be less. On the other hand, slaughtering lambs at about 44 kg weight could be recommended to farmers, who aimed to obtain as much quality lamb carcasses as possible without any negative influence on meat quality.

Red Meat Price Volatility and Its Relationship with Crude Oil and Exchange Rates in Turkey with the Approach of GARCH (p, q) Model

Turkey's agricultural commodity prices are volatile while they have steadily increased over time. A substantial amount of research has been done on the variations in these prices by looking at other commodities like energy. As a result, the connections between agricultural and energy markets have been widely explored. There is a great concern about how red meat prices in Turkey are getting increasingly fluctuating. On the other hand, we may assume that ups and downs movement in the prices of crude oil and exchange rates are connected to veal and lamb carcass prices and that volatility is transmitted to those meat prices. This study uses the generalize all period unconstraint volatility model, which generalizes the GARCH (p, q) model, to examine the veal and lamb prices volatilities in Turkey and their relationship with crude oil as well as exchange rates (data are weekly covering from May 2006 to February 2017). According to findings, red meat prices have been volatile over the previous decade, notably between 2009 and 2012. Furthermore, crude oil prices have an important impact on the prices of veal and lamb and their prior times statistically. Also exchange rates at t-2 and t-4 time have an impact on lamb prices but none at all on veal prices. Subsequently, red meat price rise and volatility are becoming an important problem for Turkey, and the policies made in this area need to be evaluated.

Performance, gastrointestinal morphometry, carcass and non-carcass traits in sheep finished on diets containing canola (Brassica napus L.)

The objective of this study was to evaluate performance, gastrointestinal morphometry, carcass, and non-carcass traits in lambs finished on different levels of canola grain in the diet. Twenty-seven Santa Ines lambs with an average initial weight of 19.33 ± 1.39 kg were given different levels of canola grain in the diet: 0, 8, and 16%. Weights and body condition scores were determined at the beginning, every 14 days and at the end of the experimental period. Animals were slaughtered to assess gastrointestinal morphometry, carcass and non-carcass traits. The statistical design used was completely randomized. The inclusion of canola grain showed a linear effect (0.723) for the width and height of ruminal papillae in the ventral region of the rumen. Intestinal villi and crypts showed a quadratic effect, with peaks of 0.62 µm and 0.43 µm, with the inclusion of 8 and 16%, respectively. When evaluating carcass traits, a decreasing linear effect was found for hot and cold carcass yield with 16% inclusion of canola. Canola grain can be used as an alternative in diets for finishing sheep up to 8% inclusion in the diet without affecting performance, ruminal and intestinal histometry, carcass, and non-carcass traits.

Assessing the Feasibility of Using Kinect 3D Images to Predict Light Lamb Carcasses Composition from Leg Volume.

Simple SummaryThe present study aimed to evaluate the accuracy of the leg volume obtained by the Microsoft Kinect sensor to predict the carcass composition of twenty-two male light lambs. The carcasses were divided into eight cuts, which were grouped according to their commercial value into high-value, medium value, and low-value. Several linear, area, and volume leg measurements were performed to predict cut and carcass composition. The leg volume determined by 3D image reconstruction using Microsoft Kinect sensor and Archimedes principle shows the higher correlations values with cuts and carcass. Additionally, it was observed that the models, which include the leg volume obtained by the Kinect sensor, are very good in predicting the weight of the medium value and leg cuts (R2 of 0.763 and 0.829, respectively). Thus, the results of this study confirm the good ability to estimate cuts and body traits from light lambs with volume measurements, particularly those obtained with the Kinect 3D sensor.This study aimed to evaluate the accuracy of the leg volume obtained by the Microsoft Kinect sensor to predict the composition of light lamb carcasses. The trial was performed on carcasses of twenty-two male lambs (17.6 ± 1.8 kg, body weight). The carcasses were split into eight cuts, divided into three groups according to their commercial value: high-value, medium value, and low-value group. Linear, area, and volume of leg measurements were obtained to predict carcass and cuts composition. The leg volume was acquired by two different methodologies: 3D image reconstruction using a Microsoft Kinect sensor and Archimedes principle. The correlation between these two leg measurements was significant (r = 0.815, p < 0.01). The models to predict cuts and carcass traits that include leg Kinect 3D sensor volume are very good in predicting the weight of the medium value and leg cuts (R2 of 0.763 and 0.829, respectively). Furthermore, the model, which includes the Kinect leg volume, explained 85% of its variation for the carcass muscle. The results of this study confirm the good ability to estimate cuts and carcass traits of light lamb carcasses with leg volume obtained with the Kinect 3D sensor.

MAGRARIO: UN NUEVO GENOTIPO PARA PRODUCIR CARNE OVINA DE CALIDAD

Generally there is poor tradition to produce and to commercialize heavy lean lamb carcasses. To achieve a better product for the ovine meat market Ideal (Polwarth) breed ewes were backcrossed to Texel breed rams (breed recognized to reduce carcass fat). Ideal breed (I) is one of the most ordinary breeds in Argentina. However, when their lambs are reared in feed-lot conditions, a high fat content is found in their lamb carcasses. After three generations of backcrosses followed by a breeding program for increase male lamb weaning weight and female fertility a new genotype was obtained for the local ovine meat production systems. This new genotype registered as Magrario (M) was obtained at Villarino Field Station of UNR (Zavalla, Santa Fe, 33º S, 61º W). It was verify that M produced more lean meat than I breed under feet lot conditions. M rams were introduced in flocks of Hampshire Down (HD) breed to evaluate lamb crosses with lean meat. Genotype M was compared under feed lot conditions with HD lambs during two months in the post weaning. Also crosses (MxHD), (MxI) and (IxHD) were evaluated in the same conditions. At the end of the experiment ultrasonic methods were used to evaluate fat depot on Longissimus dorsi. The (MxHD) showed a reduction of 20% respecting to HD. These results suggested that M genotype could be a useful paternal genotype to reduce fat depots when the aim is to produce lamb crosses under feed lot conditions in a short period of time. Key words: ovine, lean meat, feed lot, crossing.

Response to iodine supplementation in the growth and quality of Texel lamb meat

Iodine deficiency determines reproductive problems especially in the production of thyroid hormone, affecting the functions that thyroidal hormones regulate, such as energy metabolism, thermoregulation, reproduction, growth, muscle and bone tissue function. Indeed a certain concentration of iodine in the diet can promote performance in production in terms of fattening and growth. The main goal of the work was the supplementation with iodine salt from weaning to work on the production and quality of carcass and meat of early lambs of the Texel breed. Three random groups were formed. In one group, iodine salt was administered daily individually, in another group salt without iodine and finally a third "control" group without salt aggregate. All these animals were fed on natural field with an energy-protein supplement. The weaning weight and its evolution (daily gain) were determined, fortnightly until the work weight (35 kg) was reached. Blood levels of thyroid-stimulating hormone (TSH) and Selenium (Se) were evaluated. In the carcass were measured the hot and cold carcass weight, pH, colour; GR point and in the meat tenderness will be determined in the Longissimus dorsi muscle. Se concentrations, neutral detergent fiber, crude protein and iodine in pastures were also determined. The results show that no significant differences were found for any of the characters measured.

The effects of accustoming to handling during the finishing period and weaning status on stress responses to transport, and carcass and meat quality in Kivircik lambs

The aim was to investigate the stress responses to transport, and meat quality of lambs in three management strategies applied during the finishing period. At the age of 3-month, three management groups were formed according to handling procedures and the weaning status of lambs: i) unweaned (UW, n = 12), ii) weaned (W, n = 12) and iii) unweaned and also accustomed to human contact (UWH, n = 12). Transportation and slaughtering of lambs were conducted in 2 replications. Three blood samples (at farm, after transport and at slaughter) were collected from each animal. Transportation caused increases in cortisol and glucose concentrations and N/L ratio in all groups. UWH lambs had lower cortisol concentration before- and after- transport compared to UW and W lambs. UWH lambs had also lower glucose level than UW group after transportation. CK levels measured at exsanguination were significantly higher than the levels measured after transport in all management groups. Management group had no influence on carcass characteristics, except liver proportion. The meat of UWH lambs had lower pH24h values than UW and W lambs, while management group had no influence on shear force, water holding capacity and sensory characteristics. W lambs had lower meat lightness and higher meat redness than UW and UWH lambs. In conclusion, accustoming lambs to human contact during the finishing period might be recommended to the breeders to decrease the stress responses during handling and transport processes.

The effect of using complete feed containing protected soybean groats on the carcass production of thin tailed lambs

This study was conducted to determine the effect of using complete feed containing protected soybean groats on fat-tailed lamb carcass production. A total of 9 thin-tailed lambs aged 12 months were divided into 3 groups of ration treatment: the first group only received a 100% complete feed ration (P1), the second group received a 90% complete feed ration, and 10% protected soybean groats (P2), while the third group received 80% complete feed and 20% protected soybean groats (P3). Data were analyzed using a Completely Randomized Design. Differences between treatments were further tested with Duncan’s Multiple Range Test. The results showed that complete feeds containing protected soybean groats on fat-tailed lamb carcass production had no significant effect on carcass weight, carcass percentage, carcass size, percentage of carcass size, meat weight, meat weight percentage, fleshing index, but had a significant effect on carcass production. We concluded that the use of complete feeds containing protected soybean groats increased carcass production of male fat-tailed lamb.

Effects of chilling rate on progression of rigor mortis in postmortem lamb meat

This work investigated the effects of chilling rate on the progression of rigor mortis and explored possible mechanisms. Silverside from 18 lamb carcasses was assigned to control group (1.94 °C/h), very fast chilling-I group (VFC-I, 12.19 °C/h) and VFC-II group (15.10 °C/h). The shear force, myofibril fragmentation index (MFI), actomyosin ATPase activity, protein degradation and actomyosin dissociation were determined. There was no increase in the shear force in VFC-II group. The activation of actomyosin ATPase at 2–4 h postmortem in VFC-II group resulted in super-contracted sarcomeres and an increase in MFI. The degradation of μ-calpain, troponin T and desmin in VFC-II group was higher than that in control group from 6 to 24 h postmortem. These results suggested that rigor mortis was influenced which resulted in decreased shear force at a chilling rate of 15.10 °C/h by activating actomyosin ATPase and μ-calpain at early postmortem and promoted actomyosin dissociation.

PSXIV-16 Performance, carcass, wholesale, and retail cuts yield of lambs reared under thermal stress in grazing conditions and slaughtered at two body weights

Abstract Lamb production in tropical areas is conducted under heat stress in extensive grazing conditions of naturalized pastures (NP). The average daily gain (ADG) and yields of hot (HCY) and cold (CCY) carcass, wholesale cuts (WSC); neck (N), shoulder (SL), ribs 5–12 (RIB), loin (LN) and leg (LG), and detail cuts (DTC); shoulder chops (SCH), french chops (FCH), ribs (RS), back leg (BL) and shanks (SH) of 12 lambs (X = 19.4 kg) rotationally grazed (3 d occupation and 24 d resting period) for 154 or 238 d were determined. The Lambs grazed &amp;gt;8 h NP, grass hay and water were offered ad libitum, 150 g/d of a supplement (12% CP), and mineral blocks. Weekly weights were used to determine ADG. Lambs were slaughtered at 22 (SW1) or 35 kg (SM2) to determine HCY and CCY, and WSC and DTC yield as % of cold carcass weight. Performance data was analyzed as a randomized experimental (CRD) design over time. Carcass and cut yields data were analyzed as a CRD with 6 replicates per treatment. Lambs fed during 238-d had similar ADG than those fed 154-d (68.14 vs.47.74 g/d). SW1 and SW2 had similar percentages of HCY (35.21 vs. 38.14) and CCY (34.48 vs. 37.40). The WSC as % of cold carcass weight, N (6.43 vs. 7.06), SL (29.95 vs. 30.20), RIB (16.10 vs. 16.95), LN (10.84 vs. 11.33) and LG (36.51 vs. 34.44) were similar for SW1 and SW2. Yield of SCH and SH was lower (P &amp;lt; 0.05) for SW1 (15.80 and 8.11) than SW2 (23.00 and 9.11), but FCH (8.49 vs. 8.57), RS (6.89 vs. 7.00) and BL (36.52 vs 34.45) were similar. In summary, lambs slaughtered at 35 kg improved the retail cut yield, but did not influence ADG, HCY, CCY, and WCY compared to lighter lambs.

Carcass and meat characteristics of Dorper x Santa Ines lambs finished in pasture, silvopastoral system, and feedlot

The objective of this work was to evaluate the quantitative and qualitative characteristics of carcass and meat of Dorper x Santa Ines crossbred lambs finished in a silvopastoral system, pasture or feedlot. Twenty-four non-castrated male lambs were used (8 animals in each production system). The experimental design was completely randomized, with three production systems and eight replications. The production systems were: pasture of Megathyrsus maximus cv. Aruana, without shading + feed supplementation (Pasture); pasture of Megathyrsus maximus cv. Aruana, with natural shading provided by the native laurel tree (Cordia trichotoma) + feed supplementation (Silvopastoral) and feedlot. The cold carcass weight, empty body weight, cold carcass yield, fat color, fat consistency and carcass compactness index showed significant differences (P &lt; 0.05) between production systems, with higher values observed in the feedlot. The shoulder weight and the percentage of shoulder components (bones, muscle, fat and others), did not significantly differ (P &gt; 0.05) between production systems. The pasture silvopastoral systems presented similar results and also, when contrasted with the feedlot system, did not influence the parameters related to meat. Feedlot provided better quantitative and qualitative characteristics to the lambs’ carcassess.

Efecto de la raza sobre la calidad de la canal y de la carne en corderos Pampinta y su cruza con Hampshire Down

Crossbreeding is an important tool to improve sheep meat production. The objective of the present work was to evaluate the characteristics of the carcass and meat of Pampinta lambs and their cross with Hampshire Down. For the study, 23 whole male lambs were used, 11 of the Pampinta breed and 12 Pampinta crosses with Hampshire Down. The lambs were checked healthily and weighed weekly. At the mother’s foot they grazed on triticale (Triticosecale aestivum; L.) greens with vetch (Vicia sativa). They were weaned with an average weight of 20.2 (4.22) kg live weight (LW) and a WC of 2.5 on average (scale from 1 to 5). They entered a pen in a single group for 84 days. On the day of slaughter, the PV Pampinta 37.25 (1.76) kg was recorded; Hampshire Down 37.25 (1.81) kg, hot carcass weight; shaping and fattening; the fat (pelvic-renal) for the category of more than 13 kg of carcass; hot runner pH; LC and LP; AG and AT and compactness indices calculated from morphometric measurements and weight. After 12 h of maturation, PCE and pH were measured and EGD was determined in longissimus thorasis muscle; thickness of the subcutaneous tissue at the GR point; AOB; FC with the Warner-Bratzler shear; CRA and PPC. The animals were classified according to the letters S, E, U, R, O and P; according to great muscular development up to a marked muscular deficiency, and 5 degrees were stipulated for the completion, from the lack of fat coverage to the excessive presence. There was no effect of breed (P = 0.05) on all carcass characteristics. Analysis of variance (ANOVA) was used for data analysis. These results reflect differences in the conformation of the carcass.of the carcass.
