“…Previously Chambaz et al (2003) and Török et al (2009) confirmed that Angus had similar growth rate to Charolais and Simmental breeds. Bartoň et al (2007a) reported similar daily gain for Czech Fleckvieh (1 356 g/day) and Charolais (1 441 g/day). At the same time German Simmental reached the slaughter weight of 620 kg at a significantly younger age than the German Holstein bulls .…”

The objective of the trial is to compare fattening performance, slaughter results and meat quality of bulls from international cattle breeds with local Hungarian breeds fattened under the same conditions. Altogether 62 growing bulls -Angus, Charolais, Holstein, Hungarian Grey, Hungarian Simmental, Charolais × Hungarian Grey -were fattened in small groups. The daily gain varied from 897 (Hungarian Grey) to 1 240 g/day (Angus). In general, the lower gain value is caused by the semi-intensive fattening system with low concentrate supplementation. The slaughter weight showed a similar tendency as final weight, there was a significant difference between Angus and Hungarian Grey. The killing out of Charolais (59.50 %), Angus (56.80 %) and Hungarian Simmental (57.84 %) was significantly higher than Hungarian Grey (55.13 %) and Holstein (55.03 %). Due to Charolais crossing the dressing percentage of Hungarian Grey was developed by about 1.5 %.The EU conformation scores of Charolais (9.50) and Hungarian Simmental (9.33) and the fatness scores of Angus (8.33) and Charolais × Hungarian Grey (7.33) were significantly higher than that of the other genotypes. The tissue composition of dissected carcass as well as ribs joint composition determined by X-ray computerised tomography method showed the lean meat of Hungarian Simmental and bone proportions of Holstein to be the highest, whilst Angus had the highest fat content. Charolais und Hungarian Simmental had significant higher longissimus muscle area in ribs joint compared to Angus, Holstein and Charolais × Hungarian Grey. Angus and Hungarian Grey had the highest intramuscular fat level of the three examined muscles.

“…According to Bartoň et al (2006), purebred Charolais and Simmental bulls were characterised by significantly higher dressing percentage and content of prime cuts in the carcass compared with Hereford bulls; however, the rib-eye area was similar. Crossbred Charolais × Czech Fleckvieh bulls had s similar slaughter value compared to purebred Charolais bulls, according to Bartoň et al (2007). Positive heterosis for carcass weight was found in numerous studies (Hedrick et al, 1975;Koch et al, 1983;Neville et al, 1984).…”

The analysis comprised purebred Charolais bull calves (CH) and crossbred bull calves born from Hereford (CH × HE) and Simmental (CH × SI) cows. Body weights and daily gains were measured in subsequent periods of the experiment and the post-slaughter evaluation was carried out. Carcass lean weight and dressing percentage were evaluated, as well as the lean content of five prime cuts. Total weight of the five prime cuts was measured and its share in the half-carcass weight was determined. The rib-eye area was also measured. The CH × SI crossbreds reached significantly higher body weights at weaning, 210-day body weights and weights at finishing, as well as significantly higher daily gains in all the periods (P < 0.05, P < 0.01) and were characterized by the heaviest carcasses and most cuts, particularly the round. The crossbreds had the highest total weight of five prime cuts and total lean weight, highest weight of the round and lean weight in the round. Other relationships were found analyzing the share of each cut in the carcass. The share of tenderloin and rump in the carcass of CH × SI was significantly lower compared to the purebred bulls (P < 0.01) and CH × HE (P < 0.05). They also had a significantly lower share of the shoulder, shank and shin, as compared to the other groups, as well as a significantly higher (P < 0.05) share of the neck, as compared to the purebred bulls. The purebred bulls also achieved good results and had the highest share of the prime cuts and the largest mean rib-eye area.

“…The growth ability of cattle is commonly judged for genetic purposes or nutritional experiments by body weights at different ages or by average daily gains over specific periods of time (Bartoň et al, 2007). Multi-Trait Animal Models (MT) with traits defined at the specific age of animals (BIF, 1996) are currently used for genetic evaluation.…”

Daily gains of 8 243 dual-purpose bulls from 100 to 400 days of age during the years 1971 to 2007 were analyzed by random regression models. Orthogonal Legendre polynomials (LP) of degree 4 were applied to daily gains calculated at 30-day intervals over the test period. Fixed curves were estimated within the station-year-season of birth. The models also included a fixed station-year-season of weighing, animal additive genetic effects and animal permanent environmental effects. The peak daily gain was attained between 230 and 280 days of age, which corresponded to the period of the lowest variance in daily gains. Heritability estimates of daily gain were in the range of 0.014 to 0.043. The reliability of composite trait -cumulative gains over the entire period was 0.87. Genetic correlations between gains at different ages were high for adjacent ages and decreased with increasing difference in ages. Correlations of permanent environmental effects were high for adjacent ages, but became negative for ages that were far apart, indicating the possibility of compensatory growth. The phenotypic correlations were close to zero. The correlations for cumulative daily gains were higher than those for individual daily gains.
