The aim of this study was to investigate of beef breeds - Hereford (HE), Charolais (CH) Limousine (LI), Simmental (SM), Belgian Blue (BB) and Salers (SA) - of the bulls, which are used for dairy cows and heifers insemination, influence on male sex offspring carcass weight and yield. In this article, for analysis were used of all in 7 months in one slaughterhouse slaughtered bulls 12-30 months of age data. Of these 689 crossbreeds, whose cow was dairy and bull was beef breed. For this study was used only crossbreeds (689 bulls) data. This is the thirty-six (36) bull offspring from 546 farms. Bulls were divided into groups according to age during slaughter (12-18 months, 18-24 months, 24-30 months). Studies have shown, that the father's breed at different growth periods had a different effect on carcass traits of crossbreeds. Therefore, the crossbreeding use on purpose to improve dairy breeds offspring carcass characteristics, it is necessary to carefully choose the right breed for crossbreeding, bearing in mind, what age of the offspring will be slaughtered.

A total of one hundred and twelve day-old broiler chicks (Amo strains) were used to evaluate carcass traits fed with diets containing graded levels of treated sesame waste and its appropriate level of inclusion in the diet. The experimental birds were randomly allocated to four dietary treatments of 28 birds per treatment and each treatment was replicated four times with seven birds per pen. Results obtained showed that there were significant (P<0.05) differences in terms of weight (g), pluck weight (g), carcass weight (g), intestinal weight (g) and liver weight (%). Non-significant (P<0.05) difference were observed in terms of intestinal length (cm), wing weight (g), thigh weight (g), head & legs (%), gizzard (%), lungs (%), heart (%) liver (%), kidney (%) and spleen (%).

Growing Period

In 1984–1985 and 1985–1986 groups of 136 and 127 male calves were used to assess the effects of multiple implants (Ralgro and Steeroid), castration time (early and late) and castration method (surgical and chemical) on growth to weaning and feedlot performance and carcass characteristics. Ralgro increased calf rate of gain to weaning (P < 0.05) and adjusted weaning weight (P < 0.01) but did not affect rate of gain during the feedlot period. Although Ralgro increased (P < 0.001) weight at slaughter, it took longer (P < 0.05) for implanted cattle to reach Canada A1 than unimplanted cattle. Steeroid did not affect rate of gain to weaning but did increase (P < 0.05) adjusted weaning weight. Steeroid increased (P < 0.05) rate of gain relative to unimplanted cattle during the growing period in the feedlot and cattle implanted four times from birth to slaughter gained more (P < 0.05) than cattle implanted twice (birth and weaning). For the entire feedlot period, bulls receiving Steeroid gained faster (P < 0.05) than unimplanted bulls with no difference (P > 0.05) between implant groups (two or four implants). Ralgro implants increased (P < 0.05) carcass weight, rib-eye area and cutability while Steeroid increased (P < 0.05) only carcass weight. However, when rib-eye area was adjusted for carcass weight, the effect of Ralgro was not significant (P > 0.05). Bulls had greater (P < 0.05) shipping weight, carcass weight, rib-eye area, dressing percent and cutability than steers. Age at castration (early or late) had no effect on feedlot performance or carcass traits while method of castration (surgical or chemical) had some effects (P < 0.05) on ADG, liveweight, carcass weight and rib-eye area.

Abstract The objective of the present research was to study the potential for improvement of growth and carcass traits through Simmental (Si) × beef breed crossbreeding compared to purebred Si bulls in Finnish beef cattle population. The data collected from Finnish slaughterhouses included observations of 6 224 purebred Si bulls plus Si × beef breed crosses. For estimating valuable cuttings, a separate dataset including in total 314 bulls was also collected. The estimated average daily carcass gain of the purebred Si bulls was 686 g/d and it improved by 3 and 6% with Si×Blonde d’Aquitaine and Si×Charolais crossbreds, respectively. Carcass conformation improved by using Blonde d’Aquitaine, Limousin and Charolais crossbreeding compared to the pure Si bulls. Si×British breed crossbreds (Angus and Hereford) had poorer carcass gain and produced poorer conformed carcasses compared to purebred Si bulls. Furthermore, the yield of subcutaneous fat was higher in the Si×Angus and Si×Hereford bulls than in the purebred Si bulls.

Liveweight and carcass traits of 3-way Africander (A) x Simmental (S) x Hereford (H) crossbreds and purebred Herefords were monitored predominately on native pastures at Dirranbandi, Queensland, for 2 calf crops over 6 years. The relative breed compositions of the crossbreds were A4S2H2, A4S 1 H3 and A4H4. The mean liveweight of the A4S2H2 cattle ranked highest from about 250 days post-weaning to slaughter (520 days post-weaning) for steers, and at first joining for heifers (560 days post-weaning). Differences in liveweight were not significant at all times. The A4S2H2 and A4SlH3 steers had the highest (P<0.05) post-weaning average daily gains. Differences in weaning weight between crossbreds were carried through to slaughter for steers and to joining for heifers. The A4S2H2 steers had the highest (P<0.05) mean final liveweight (433 kg) and mean carcass weight (232 kg). There was no difference in carcass weight between the other crossbreds and Herefords. Fat depth at the P8 rump site of A4H4 crossbreds (8.5 mm) was higher (P<0.05) than that of Herefords (5.5 mm) and other crossbreds. Dressing percentages were similar for all breed types. The A4S2H2 maiden heifers had higher (P<0.05) liveweights at first joining (369 kg) than the A4S1H3 (353 kg) and A4H4 (337 kg) heifers. These data show that beef producers in southwestern Queensland can increase carcass weights with A4S2H2 crossbreds and produce carcasses that primarily meet the Korean-EC market and the requirements of domestic supermarket outlets.

The objective of the present study was to determine growth and carcass traits of beef breed bulls and heifers in the Finnish beef cattle population. The data collected from Finnish slaughterhouses included observations of 6323 and 2385 Hereford (bulls and heifers, respectively), 4421 and 1794 Charolais, 4335 and 1951 Limousin, 4068 and 1692 Aberdeen Angus, 2151 and 774 Simmental, 344 and 147 Blonde d’Aquitaine animals. For estimating valuable cuttings, a separate dataset including in total 1112 bulls and 260 heifers was also collected. Significant breed differences were observed in growth performance, carcass traits and retail product yield. The later maturing, Continental beef breeds seem to reach higher carcass gains, produce less fat and have more valuable cuts than the earlier maturing British beef breeds. The later maturing beef breeds tend to have carcass traits that suit well in the Finnish beef production system.

The influence of breed of sire on carcass traits was examined by studying data collected on 134 steers produced by mating Shorthorn cows with Shorthorn, Angus, Hereford, and Charolais bulls. The steers were fed out in two groups: one group was slaughtered at 18 to 23 months as they reached a live weight of 900–1000 lb and the other group at approximately 30 months of age. In each group the steers sired by Charolais bulls gained more rapidly, possessed more bone, produced heavier carcass weight, and showed largest eye muscle measurements. There were no appreciable differences among the crosses within the sire groups represented by the British breeds except that Hereford × Shorthorn surpassed Angus × Shorthorn and Shorthorn in growth rate significantly and for a slight superiority in marbling for the Angus compared with the Shorthorn.

Crossing of Friesian-Holstein dairy cows with beef breed bulls is widely practised. Recently the Italian Piemontese and Romagnola beef breeds have been imported into Ireland, but they have not been evaluated. The objective of this study was to compare the progeny of these breeds and Friesians for carcass traits. General productivity traits have been reported elsewhere (Keane, 2001).

Abstract The objective of this study was to compare feedlot performance and carcass traits between two implant programs in heifers harvested at 3 different days on feed (DOF; 179, 200, or 221 d). Crossbred beef heifers (n = 3,084; 291 + 3.9 kg) were used in a 2×3 factorial arrangement of treatments in a randomized complete block design. Revalor-IH (80 mg TBA and 8 mg E2) was administered on arrival followed by Revalor-200 (200 mg TBA and 20 mg E2) 94 d before harvest (IH/200) or Revalor-XH (80 mg TBA and 8 mg E2, uncoated; 120 mg TBA and 12 mg E2, coated) was administered on arrival (XH). No implant × DOF interaction was detected (P ≥ 0.09) for any parameter. Heifers subjected to IH/200 had greater (P ≤ 0.01) final BW, ADG (P &lt; 0.01) and G:F (P = 0.01). As DOF increased, BW increased (P ≤ 0.01) while ADG (P&lt;0.01) and G:F (P ≤ 0.01) decreased. Hot carcass weight was greater (P = 0.01) for IH/200 compared with XH (367 vs. 361 kg, respectively). Heifers receiving XH had greater marbling scores (P = 0.02; 582 vs. 568) and BF (P = 0.01; 1.78 vs 1.70 cm) compared with IH/200 while re-implanted heifers had increased (P = 0.01) REA (86.5 vs. 83.2 cm2). Heifers implanted with XH tended to be fatter than those implanted with IH/200 having a greater (P = 0.01) proportion of USDA Prime and fewer (P&lt;0.01) USDA Select. Increasing DOF increased (P ≤ 0.03) HCW, DP, BF, REA, marbling, and proportion of USDA Prime carcasses. Growth performance and HCW were increased for IH/200 compared with XH heifers. Increasing DOF resulted in poorer ADG and G:F but increased HCW.

Abstract In order to maintain consumer acceptance of lamb meat, producers are aiming to produce leaner lambs through breeding for certain carcass characteristics. The Texel breed is known for its superior muscling phenotype due to a myostatin mutation. Because of this mutation, Texel and Texel cross lambs have been shown to have improved carcass lean with less fat in various locations throughout the carcass. The objective of this study was to observe the impacts of different sire and dam breeds on carcass composition. Lambs (n = 41) were produced by mating two dam breeds (Southdown or Suffolk) and two sire breeds (Southdown or Texel). Lambs were harvested and a hot carcass weight was obtained. At 24 h postmortem, a chilled carcass weight was taken, and each carcass was split in half. The left side of the carcass was cut into the four primal cuts and scanned using a DXA. The right half was used for standard carcass variables. After DXA scans, each primal was weighed and the major muscles were dissected from the primal cuts and weighed. Subsamples of muscles were used for total lipid analysis and Warner-Bratzler Shear Force testing. DXA scans showed a difference in the primal cut mass (P = 0.0207) with the Suffolk-Texel cross having the highest average primal cut mass at 12.52 kg. Southdown-Southdown lambs had the highest fat percentage (dam P = 0.0398; sire P = 0.0116). Dam breed had a more significant effect on muscle toughness (P &lt; 0.0035). Southdown sired lambs had a higher SFA (P = 0.0046) and MUFA (P &lt; .0001) but Texel sired lambs had a higher overall fatty acid ratio (P &lt; .0001). On average, the Suffolk-Texel cross was shown to have heavier average weight for the primal cuts in the rack and leg, which are where some of the more profitable cuts of meat are located.
