“…The average CW values in our case correspond to [10,21,22]; however, these are significantly lower than [20] and, conversely, higher than [23]. Similar values were found in the case of average BW values [10], while higher values for the Czech Fleckvieh breed are registered in [7,8]; however, lower values have also been recorded [16]. Higher CDG or comparable values are demonstrated in [1,9,20] or [21].…”

The goal of this study was to analyze the genetic and environmental factors of selected meat yield indicators in Fleckvieh cattle in the Czech Republic, through the application of station (S) and field (F) testing methods. Data collected from fattened bulls were analyzed for F (n = 9378) and for S (n = 6346). In the F method and the S method, the values of the main meat yield indicators were as follows: carcass weight 402.91 kg (F), 339.37 kg (S); carcass daily gain 626.05 g/day (F), 609.74 g/day (S); SEUROP carcass classification 2.73 (F), 2.19 (S). Environmental factors were found to have a significant impact on the selected meat yield indicators; their heritability ranged from 0.14 (SEUROP classification) to 0.33 (dressing percentage). The genetic trend was significantly positive only in relation to those meat yield traits, which had a positive link to the size or weight of the animal. The genetic correlation between observations obtained in the S and F methods of testing was very high in relation to the carcass daily gain (0.8351) and carcass weight (0.8244), while slightly lower correlations were calculated for the SEUROP classification. A genetic evaluation of the degree of fatness is not routinely performed in Fleckvieh populations, and the newly established heritability for this trait ranges between 0.17–0.20. The genetic correlation between beef yield indicators and the exterior trait of muscularity was also established, and shows a strong link to the net daily gain, the SEUROP classification and body weight (0.79–0.97). The aim of the study was to evaluate the genetic and environmental effects on meat yield and also estimate genetic parameters for new traits. We can also state, based on the results, that a strong positive genetic trend is confirmed, especially in traits related to the size or weight of animals. This result can be used in breeding programs of dual-purpose cattle, where we can genetically improve the meat and milk yield through the body size.

“…At the start (3.3-3.8 months old), the liveweight of the C steers was 25 kg higher than for D steers, and at slaughter this breed difference had increased to 42 kg across the two feed intensities. This result was a surprisingly low increase in difference compared to that in previous studies [14][15][16]37]. However, those studies generally used higher feed intensities, even compared with the production system with a moderately high feed intensity (H) strategy in the present study.…”

“…The superiority of dairy × beef crossbreeds compared to pure-bred dairy cattle has been established in previous studies, but mainly in intensive rearing conditions [14][15][16]. Eriksson et al [17] show that the breed effect of using beef breed sires for dairy cows is greater in intensive than extensive production systems, as the genetic potential of the beef breed can be utilized in the former.…”

This study compared animal performance and carcass characteristics in steers born to a dairy breed dam and a dairy or beef breed sire allocated to one out of two production systems, both including grazing semi-natural pastures during summer. Spring-born groups comprising 16 purebred dairy (D) steers and 16 dairy × Charolais crossbreeds (C) were allocated to moderately high indoor feed intensity with slaughter at 21 months of age (H), while two corresponding autumn-born groups of 16 D and 16 C animals were allocated to low indoor feed intensity with slaughter at 28 months of age (L). The animals were mainly fed grass-clover silage while housed. The H steers grazed semi-natural pastures for one summer, whereas the L steers grazed semi-natural pastures for two summers. From weaning to slaughter, liveweight gain was 0.94 and 0.77 kg day−1 for H and L steers, respectively (p < 0.0001), with no breed effect on weight gain. However, C carcasses had a higher weight, conformation score, and proportion of high-valued retail cuts than D carcasses (p ≤ 0.004). Moreover, conformation differed more between LC and LD than between HC and HD. From this study on forage and pasture-based beef production, we concluded that breed had no effect on the performance of living animals, but that dairy × beef crossbred steers produced heavier and higher-quality carcasses than pure-bred dairy steers.

“…The content of water in them decreases and the amount of contractile (actin, myosin) or respiratory proteins (myoglobin) increases depending on the type of cultivation. Meat is defined as animal muscle tissue, which consists of transversely striped muscle fibers, connective (collagen and elastic fibers) and adipose tissue (Romanova, 2016;Vestergaard et al, 2019).…”

The regularities of the post-embryonic development of farm animals have been studied by numerous researchers. Their ontogenesis is a result of the complex interaction of animal genotype with those conditions of the external environment in which their hereditary basis is realized. In Russia, the stable keeping system of the cattle is highly relevant as many farms do not have large areas allocated for natural pastures. Therefore, a task has been set to study the growth, development and beef productivity of Limousine cattle in the age aspect under stabling conditions, namely, bulls from the birth to meat production and heifers from birth to first-calf heifers. The object of research was purebred bulls and heifers of Limousine breed, which are grown on the territory of the Central Chernozem area of the Russian Federation. It has been established that intensive use of Limousine cattle contributes to the rapid increase of high-quality beef. The performed studies showed that Limousine bulls and heifers demonstrate essential differences in growth intensity. In main age periods, bulls outnumbered heifers by 160.2 kg in live weight and 451.6 grams in average daily growth and also proved to be more stress-resistant to changes in external conditions. When estimating beef productivity, limousine bulls are characterized by a rather high live weight of 688.7 kg. The slaughter yield of 20 monthly bulls was 63.2%.
