“…Between the 100 th and the 200 th day, the growth intensity of lambs decreased, however the lambs of the breed Ch were still characterized by higher (p < 0.05) daily gains (234.50 ± 71.2 g. da y−1 ) than the lambs of the SF breed (181.50 ± 38.4 g. da y−1 ). Petr et al (2009) also observed significant (p < 0.05) differences between mean daily gains in the same sheep breeds. An interesting finding is the change of growth intensity in both breeds in the interval from 200 to 300 days of age, when the growth accelerated in the SF breed (243.40 g/day) and decreased in the Ch breed (132.30 g/day).…”

The aim of the study was to evaluate the influence of breed (Suffolk, Charollais), sex (ram, ewes) and litter size (singles, twins, triplets) on the growth ability of lambs from birth to 300 days of age. Insignificantly higher (p > 0.05) birth weight (4.47 ± 1.07 kg), weight in 30 days (13,87 ± 3.28 kg), 100 days (36.51 ± 5.80 kg) and 300 days (79.00 ± 13.64 kg) was found in the lambs of the Suffolk breed. Higher birth weight was also associated with larger body dimensions in the Suffolk breed (height at withers 42.43 cm, diagonal length of body 43.60 cm). In 100 days, the lambs of Charollais were slightly bigger, in 300 days the height at withers and the diagonal length of body were nearly the same in both breeds. Higher growth intensity was recorded in rams (DG0−300: Ram = 239.87 g. day−1, Ewe = 221.67 g. day−1). With regard to the litter size, higher growth intensity was found in singles (234.77 g. day-1) when compared to lambs from twins (226.10 g. day−1) or triplets (225.63 g. day−1).

“…The genotype had no signifi cant eff ect on most of the monitored growth parameters. In contrast, Shaker et al (2002) and Burke et al (2003) reported a signifi cant eff ect of this factor on growth while Petr et al (2009) discovered signifi cant eff ect of this factor on LW 0 and DG 0-100 only. In terms of the individual genotypes the LW 0 ranged from 3.51 to 4.19 kg, while the lowest was found out in S 100 and the highest in S 50 T 50.…”

The aim of the study was to evaluate the eff ect of a genotype on growth and basic carcass characteristics in male lambs. The experiment was carried out at an organic farm in Proseč and four diff erent genotypes were included in the experiment: Šumavská sheep (S) 100, n = 8; S 50 Texel (T) 50, n = 11; T 75 S 25, n = 13 and S 75 T 25, n = 11. The genotype had no signifi cant eff ect on most of the monitored growth parameters. The highest daily gain (DG) in the interval from birth to 100 days of age was found out in S 75 T 25 (327 g) but the highest DG from birth until the end of the experiment was found in S 50 T 50 (199 g). By contrast, the lowest DGs in both above mentioned intervals were found out in S 100 (265 and 147 g, respectively). With regards to basic carcass characteristics, the genotype had a signifi cant eff ect only on proportion of kidney. The highest carcass yield (44.80%) was found in S 50 T 50 and the lowest (37.66%) in S 100. The best conformation score was found in S 75 T 25 (3.18) and the lowest fatness score in S 50 T 50. To conclude, it is possible to state that use of the Texel rams in crossing with the Šumavská ewes had a positive eff ect on both growth and basic carcass characteristics.

“…Texel lambs weighed an average of 28.388 kg over the five years evaluated. Lower weight (26.95 ± 1.21 kg) was published by Petr et al (2009). In Suffolk, the weight of non-inbred lambs was significantly higher compared to inbred lambs, as was the case with Texel lambs.…”

The aim of this study was to present the trend of inbreeding and to estimate the effect of inbreeding on the growth ability of lambs in the three most common sire breeds in the Czech Republic: Suffolk (SF; n = 49 345), Charollais (CH; n = 14 189) and Texel (T; n = 10 481). The growth ability of lambs was evaluated between 2000 and 2019 based on the weight at 100 days of age. The average inbreeding coefficient for Suffolk, Charollais and Texel was 0.013, 0.012 and 0.011, respectively. The average number of known generations was 5.260 for Suffolk, 3.355 for Charollais and 3.709 for Texel. To evaluate growth ability, lambs were divided into four groups according to the inbreeding coefficient (F = 0.00, 0.00 < F ≤ 0.062 5, 0.062 5 < F ≤ 0.125, F > 0.125). The results of this study show the negative effect of inbreeding on the growth ability of lambs was significant (P < 0.05). The regression coefficients of the weight for Suffolk, Charollais and Texel lambs for a change of 1% in inbreeding were estimated to be –0.028, –0.053 and –0.048, respectively.
