Carcass characteristics of 3673 steers and heifers born over a 6-yr period from 1973 to 1978 at Brandon, Manitoba (farm conditions) and Manyberries, Alberta (range conditions) were compared. Calves weaned at Manyberries were fed and evaluated at Lacombe, Alberta. The progeny produced were out of 10 specific F1 crosses of dam mated to bulls of the Charolais (C), Simmental (S), Limousin (L) and Chianina (Chi) breeds. Dam crosses included the Hereford × Angus (HA) and crosses sired by C, S and L sires out of H, A and Shorthorn (N) dams. The progeny from SN dams (Brandon) and the three S-cross dams (Lacombe) had the highest carcass weight per day of age and the progeny from LH dams (Brandon) and L dams (Lacombe) the lowest and equal to progeny from HA dams. The progeny from LN dams (Brandon) and the three L-cross dams (Lacombe) had the highest dressing percentage and the progeny from the SH dams the lowest and equal to the HA progeny. The progeny from HA dams at both locations had greater levels of average rib fat than progeny from the exotic-cross dams. At both locations, the largest rib eye area/wt (cm2/kg) was recorded by progeny from the LA dams and the smallest by progeny from the SN and CN dams and they did not differ from the HA progeny. The progeny from all exotic-cross dams at both locations recorded a higher proportion of round than progeny from the HA dams with the highest proportions being recorded by the progeny from LH dams (Brandon) and progeny from CH, CN and SN dams (Lacombe). The progeny from HA dams (Lacombe) exceeded the progeny from all exotic-cross dams in the proportion of long loin while the progeny from HA dams (Brandon) exceeded the progeny from CA, CN and SN dams. In percentage of lean in the round, the progeny from CN, SH and SN dams (Brandon) and SN dams (Lacombe) were the lowest and equal to progeny from the HA dams. The progeny from HA dams at both locations generally had the lowest percentage of bone in the long loin with progeny from the SN dams (Brandon) and progeny from CH dams (Lacombe) recording the highest percentage. The progeny from the SN and CH dams (Brandon) and the progeny from the SH and SN dams (Lacombe) recorded the highest percentage bone in the round with the progeny from CA, CN and LN dams (Brandon) and progeny from CA, SA, LH and LN dams (Lacombe) the lowest and equal to the progeny from HA dams. The progeny from exotic cross dams at both locations exceeded the progeny from HA dams in percentage lean per day of age for the combined trait long loin and round. The progeny from L-cross dams (Lacombe) had the highest lean-to-bone ratio of the combined trait long loin and round with the progeny from HA dams intermediate and equal to the progeny from the other dam crosses. At Brandon, the progeny from the LA dams had the highest lean-to-bone ratio with the progeny from the CH, CA, CN, SA and LH the lowest and equal to the HA progeny. Dam by year, dam by sex, year by sex and the genetic interaction involving breed of sire and breed of dam were not statistically significant. Key words: Cattle, breeds, carcass, cuts, composition

Carcass characteristics of 3673 steers and heifers born over a 6-yr period 1973–1978 at Brandon, Manitoba (farm conditions) and Manyberries, Alberta (range conditions) were compared. Calves weaned at Manyberries were fed and evaluated at Lacombe. The progeny were out of 10 specific F1 crosses of dams mated to bulls of the Charolais (C), Simmental (S), Limousin (L) and Chianina (Chi) breeds. Dam crosses included the Hereford × Angus (HA) and crosses sired by C, S and L sires out of H, A and Shorthorn (N) dams. Breed of sire of dam effects indicated that progeny from S cross cows generally had the heaviest carcasses S = C > L, the greatest carcass weight per day of age S = C > L, the highest percentage of dissected bone of the round S > C > L and rib S > C = L, the highest proportions of brisket S > L > C and flank S > L = C, and carried more kidney fat (percent liveweight) S > C = L and average rib fat S > C = L. Progeny from Limousin and Charolais cross cows had the highest dressing percentage [Formula: see text] and rib eye area/100 kg carcass wieght L > C > S while those from Limousin cross cows had the highest proportion of long loin and the combined lean cuts (rib, round and long loin) a higher percentage of dissected lean in the round L > C > S and the highest lean-to-bone ratio L > C > S. Progeny from dams of Shorthorn breeding generally had the heaviest carcasses, the greatest carcass weight per day of age, the highest percentage kidney fat and at Brandon the greatest proportions of plate and brisket. Hereford cross dams consistently produced progeny with the highest percentage head H = A > N, hide [Formula: see text], feet H > A = N, percentage bone in the long loin [Formula: see text], round [Formula: see text], and rib [Formula: see text], and the highest percentage lean in the long loin H > N (Brandon) and chuck H > N (Brandon). The progeny from Angus cross dams carried the greatest average rib fat [Formula: see text], had the greatest rib eye area/100 kg carcass weight [Formula: see text], the highest percentage lean in the round [Formula: see text], and the highest lean to bone ratio A > H = N.

The growth and carcass characteristics of first-cross Border Leicester x Merino ram, cryptorchid and wether lambs were compared over a range of slaughter weights (35-55 kg). Lambs were offered feed ad libitum after weaning. The growth rate of wether lambs (221 g/day) was less (P< 0.01) than that of rams and cryptorchids (308 and 280 g/day respectively, P = 0.076). The dressed carcasses of the wether lambs were approximately 2 percentage units heavier than those of the ram and cryptorchids, but this difference was partly due to the weight of the testes. Across all sex groups, dressing percentage increased by 0.46 percentage units per kg increase in carcass weight. The carcasses of rams and cryptorchid lambs tended to be leaner than those of wethers. Fat score distributions, based on export standards, were such that wethers scored higher (fatter) than rams and cryptorchids (P< 0.05). There was a significant sexx carcass weight interaction with GR tissue depths. Above 17 kg carcass weight, tissue depth of wether lambs was greater than those of the other sex types. Of 12 families assessing consumer acceptability (taste, smell, size, fatness and tenderness) of leg roasts, the majority showed no preference for any of the sexes.

Carcass characteristics of 3673 steers and heifers born over a 6-yr period (1973–1978) at Brandon, Manitoba (farm conditions) and Manyberries, Alberta (range conditions) were compared. Calves weaned at Manyberries were fed and evaluated at Lacombe. The progeny produced were out of 10 specific F1 crosses of dams mated to bulls of the Charolais (C), Simmental (S), Limousin (L) and Chianina (Chi) breeds. Dam crosses included the Hereford × Angus (HA) and crosses sired by C, S and L sires out of H, A and Shorthorn (N) dams. Terminal sire breed differences in the paired comparisons involving progeny of the Chi (the comparisons with maximum degrees of freedom) indicated that their carcass weight per day of age averaged 1.1% greater than C, 3.6% greater than S and 6.4% greater than L at both locations [Formula: see text]. Simmental progeny had significantly heavier (P = 0.0001) hide weights as a percentage of liveweight and significantly lower (P = 0.0001) dressing percentages than the progeny from C, L and Chi sires. Limousin and Chi-sired progeny had the lowest percentage of hide weight and the highest dressing percentage. Limousin progeny averaged 5.2% greater rib eye area/wt (cm2/kg) than Chi progeny P = 0.0001). Chianina progeny had the lowest proportions (percent of hot carcass weight) of long loin, rib, brisket and flank and the highest proportions of round and the combined trait of rib, round and long loin (P < 0.05). Chianina progeny had the highest percentage of lean in the rib, chuck and long loin while L-sired progeny had the highest percentage lean in the round. Chianina progeny had the highest and L progeny the lowest percentage bone in the rib, chuck, round and long loin. Limousin progeny had the highest lean:bone ratios but least percent lean per day of age at the long loin and round. At both locations significant terminal sire breed by year interactions were observed for all traits. The interactions of breed of dam by year, by sex, and by breed of sire and the interaction of year by sex were nonsignificant. Key words: Cattle, breeds, carcass, cuts, composition

The aim of this study was to evaluate growth ability (weight, daily weight gains) and selected carcass characteristics during fattening period of Wagyu × Aberdeen Angus crossbred steers (F1). A total of 72 animals were evaluated over a period of 4 years. The observed animals were monitored from rearing (8 months) to slaughter (30 months). Statistical evaluation was performed by SAS 9.3 (GLM procedure); variables were corrected for effects of the year, season of birth and sire effect. Sire effect proved to be the most significant in our evaluation. Offsprings sired by Bull 1 had significantly (P < 0.05) better growth ability than offsprings of other two tested bulls. Slaughter analysis of tested steers showed, that mean value of dressing percentage was 55.61 %. Significantly highest dressing percentage was found for Bull 1 offsprings (56.72 %, P < 0.05). The average carcass weight of tested steers was 443.46 kg and the highest carcass weight was again achieved by offsprings of Bull 1 (486.39 kg; P < 0.05). Average value of beef marbling score was 5.21. Slaughter analyses of carcass cuts (cut‑out, round, chuck, rump, tenderloin, shank, flank) and tallow showed that average weight of these lean cuts was 127.32 kg and tallow content was 39.31 kg at average. The highest values of these parameters were observed in offspring of bulls Bull 1 (P < 0.05).

The aim of our study was to assess the dynamics of the characteristics in pig carcasses as affected by the season and year of slaughter. A total of 106 027 carcasses of growing-finishing pigs of commercial production, slaughtered in the same abattoir in 2014 and 2015 were included in the study. The carcasses were classified using UltraFOM 200 device, as the characteristics controlled were back-fat thickness at two locations and the depth of m. Longissimus dorsi. These measurements were used to further determine the lean meat percentage. The results of the study showed significant differences in the dynamics of changes of carcass characteristics during the seasons and the years. The highest lean meat percentage was found in summer (56.48%), followed by spring (56.34%), autumn (56.29%) and winter (56.10%). On the other hand, the pigs slaughtered in winter displayed highest carcass weight and back-fat thickness at both locations.

Abstract The objective of this study was to evaluate the optimal time to reimplant following an initial implant on performance and carcass characteristics when steers were fed for 180 d. Crossbred steers (n = 800; initial BW = 330 ± 25 kg) were utilized in a generalized randomized block design and assigned randomly to pen, and pen assigned randomly to one of five treatments. Treatments included 5 different days on terminal (DOT) implant (160, 120, 100, 80 or 40 DOT). All steers were given an initial implant (80 mg trenbolone acetate (TBA) + 16 mg estradiol; Revalor-IS) on d 1. Terminal implant consisted of 200 mg TBA + 20 mg estradiol (Revalor-200). Dry matter intake was the least for 40 DOT (P ≤ 0.04), with no differences between the other treatments (P ≥ 0.11). Carcass-adjusted final BW responded quadratically (P = 0.03) with 100 DOT having the greatest final BW but was not different from 120 DOT (P = 0.82). Carcass-adjusted ADG and G:F responded quadratically (P = 0.02 and P < 0.01, respectively). When solved for the first derivative, carcass-adjusted ADG and G:F were maximized at 99 and 87 DOT, respectively. However, there was less than a 2% difference in carcass-adjusted ADG and G:F between 80 and 120 DOT. Hot carcass weight responded quadratically (P = 0.03), with the greatest HCW at 100 DOT. Solving for the first derivative, HCW was optimized at 104 DOT. There were no differences in back fat, marbling, or yield grade (P ≥ 0.27). Overall, administering an initial implant followed by a terminal implant 85 to 105 d prior to harvest increased gain, efficiency, and HCW in steers when fed for 180 d. Minimal changes in performance and carcass characteristics when steers are reimplanted 80 to 120 d prior to harvest suggests flexibility in reimplanting windows.

Clover Content

Lambs from the Poll Dorset x (Border Leicester x Merino) cross were raised from a late lambing in 1983 (a year when pastures grew unchecked and had high clover content) and 1984 (a year with intermittent dry periods and a low clover content in pastures). Multivariate repeated measures analyses were used to compare growth rates for rams, wethers and ewes within 2 periods of growth in 1983, and 4 in 1984. In all stages rams grew significantly faster than wethers and ewes, whereas wether growth rate exceeded that of ewes in only 3 stages. In general, when pasture availability and quality was high, rams grew faster than wethers by 0.3 kg/week and ewes by 0.5 kg/week. The rams grew 0.16 kg/week faster when pasture availability was limiting for a period in winter but lost significant (P<0.01) body condition, whilst ewes maintained both weight and condition. When good quality feed was again available, rams gained more weight than wethers, as did wethers compared with ewes, while rams and wethers gained more condition than ewes. Carcass weight and fatness, measured either as indicators of fat (GR measurement or fat score) or as total subcutaneous fat, could be predicted from assessments made on live lambs. Full liveweight, sex and year explained 41% of variation in GR, 48% in fat score and 79% in subcutaneous fat. Condition score, sex and year explained 45% of variation in GR, 52% in fat score and 57% in subcutaneous fat. Full liveweight, condition score, sex and year explained 80% of the variation in subcutaneous fat, 47% in GR and 57% in fat score. An interaction of sex with full liveweight in predicting carcass weight and subcutaneous fat indicated that as carcass size increased, the sex of the lamb became an increasingly important consideration when assessing characteristics important in describing lamb carcasses. Dressing percentage decreased by 0.08/kg as liveweight increased. This result was consistent over the 2 years, with opportunities for error being assessed and eliminated in the second year. Notwithstanding that this was an unimportant loss in real terms, published information showed an increase in dressing percentage with liveweight.

The present study was conducted to determine the slaughter and carcass traits of male lambs of the Akkaraman (A), Morkaraman (M), Awassi (IW), Karayaka (KR), Kıvırcık (KV) and Middle Anatolian Merino (MAM) sheep breeds. Fattening of all lambs started when they were at 90 days at weaning and finished when they reached bodyweight of 40 kg. The cold dressing percentage of lambs of A, M, and IW breeds were significantly lower than those of KV, KR and MAM. Fat depth and muscle area were significantly greater in KV and MAM lambs than those of the other breeds. There were significant differences among breeds in shoulder, leg and lean weights. Weights of back loin in KV and MAM lambs were significantly greater than those of the other breeds. The highest values for carcass fleshiness were obtained in MAM and IW lambs, but they had a significantly lower carcass fatness score. There were significant differences among the breeds in carcass compactness and leg conformation. The results of the present study indicated that A and MAM breeds could be recommended for desirable carcass characteristics.Keywords: Carcass cuts, indigenous sheep breed, intensive lamb finishing, meat formation, SEUROP classification

Data on 42 halothane-sensitive pigs (HSL, nn-genotype), 169 Lacombe pigs (LAC, NN-genotype), 41 crossbred pigs (XBD, Nn-genotype), and 72 Yorkshire pigs (YRK, NN-genotype) representing 145 gilts and 179 castrates, were obtained over the liveweight range from 74.0 to 134.5 kg (average 105 kg) to examine the effect of genotype, gender and slaughter weight on the composition of the four lean cuts (ham, loin, picnic and butt). Gilts had a greater proportion of dissectible lean from lean cuts than castrates (557 ± 2.8 vs. 525 ± 2.6 g kg−1). The HSL pigs had the highest and LAC pigs the lowest commercial dressing percentage, increasing respectively from 85.3 to 86.0% and 79.7 kg to 82.6% as slaughter weight increased from 80 to 130 kg. Corresponding figures for XBD and YRK pigs, were 82.5 to 85.4 and 80.6 to 84.6%, respectively. Dissectible lean from lean cuts from 65-kg carcasses was 606, 525, 536 and 575 g kg−1 for HSL, XBD, LAC and YRK pigs, respectively. Corresponding figures for 85-kg and 105-kg carcasses were 574, 525, 515, and 555 g kg−1 and 542, 525, 494, and 535 g kg−1, respectively from HSL, XBD, LAC and YRK pigs. LAC and YRK pigs, each with exclusively NN-genotypes but differing in composition of lean cuts, maintained their relative differences in composition over the weight range studied. Heterogeneity of slopes for changes in proportion of lean in the lean cuts with increasing weight among the HSL, XBD and LAC pigs implied a genotype × weight interaction that could best by explained by an apparent increase in the dominance of the halothane gene with increasing carcass weight.
