The aim of this work was to evaluate growth potential of Blue‑Grey cattle in Czech conditions as the compare its growth traits to initial population. Suitability of specific conditions was evaluated based on growth ability and daily weight gains (DWG). Tested breeds included Shorthorn, Galloway and their crossbred variation called Blue‑Grey cattle. A total of 428 animals were evaluated over a period from 2010 until 2016. Birth weight, live weight at 120, 210 and 365 days of age was monitored for each animal. Also, DWG at 120, 210 and 365 days of age was part of the evaluation. Mixed model (SAS 9.3) was used for statistical evaluation. The influence of sex on growth ability was significantly (P < 0.05) in favour of bulls throughout the evaluated period. Purebred Shorthorns achieved highest weights (from + 2.5 for birth weight to +82.65 kg in weight at 365 days of age) (P < 0.05) and DWG (from + 147.26 g to + 300.37 g (P < 0.05) compare to purebred Galloway throughout the evaluated period. Weight and DWG of Blue‑Greys were significantly better in comparison with Galloway and were more comparable with Shorthorns. Therefore, growth ability was improved mainly by addition of Shorthorn blood. Good growth ability of Blue‑Greys combined with better environmental endurance from Galloway blood makes them well suited for use in organic farming conditions of Czechia.
