“…However, a er reaching 100 days of age in all groups of lambs a decrease in growth was monitored. This fact can be explained by weaning of lambs and the gradual deterioration of the pasture quality while the above mentioned result is consistent with conclusions published by Simeonov et al (2014). In conclusion to the evaluation of growth it must be noted that the highest daily gains for the whole period of the experiment were found out in S 50 T 50 and S 75 T 25.…”

“…The growth is aff ected by many factors where the most important are the breed, nutrition, sex, litter size, management, health and age of mothers. The eff ect of sheep genotype on growth was evaluated by Burke et al (2003), Kremer et al (2004) and Simeonov et al (2014). Also a carcass value of lambs is aff ected by a great number of diff erent factors where the most important are the breed, nutrition, sex, management and health.…”

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.

“…The weaning weight of lambs born from sheep with twins or singletons did not differ (P > 0.05). Lambs born in doubling birth weaned later 23.1 d (doubling birth) versus 20.6 d (no doubling birth) (Simeonov et al, 2014). Twins are born smaller than singletons, this has been assumed to be secondary to limited nutrient supply in late gestation.…”

“…Factors, such as the type of birth, the sex of the lamb and the age of the ewe at lambing, may affect the require development of lambs (Carneiro et al, 2007). The difference in live weight is largely related to sex and type of birth (Simeonov et al, 2014). During the first 14 days of the suckling period the growth of lambs depended mainly on the amount of suckled milk.…”

The aim of the present study was to analyze live weight and growth data of live weight at birth to 24.5-25.5 kg in weaned Dorper crossbred lambs. A total of 93 Dorper crossbred born lambs (½ Dorper + ½ Santa Inês) were evaluated, with percentage of 17.7 double (twin couple = 21%, twin with only females = 50%, twin with only males 29%). The sex of the lamb influenced (P < 0.05) the live weight at birth total (LWB total) and live weight at birth average (LWB average) , the male lambs had in both characteristics superior values. No differences (P > 0.05) were found for the age at weaning (AW), live weight at birth total (LWW total ) and live weight at weaning average (LWW average ) . For the type of birth all characteristics were significant (P < 0.05). For doubling birth the characteristics LWB total , AW and LWW total had higher values

“…There are a number of factors, whether external or internal, which effect carcass value and meat quality. Out of internal influences, breed plays a significant role according to Dobeš et al (2007), Simeonov et al (2014), Turner et al (2014), Souza et al (2016), Komprda et al (2012) and Jandasek et al (2014). The aim of this study was to evaluate the effect of the breed and line on slaughter value and quality of lamb meat.…”

The aim of our experiment was to evaluate to what degree carcass value and quality of lamb meat are effected by selected breeds (Zwartbles, Suffolk, Romney Marsh) and lines (Zbyšek, Ztepl, Záblesk, Ewebank Armani, President, Romeo, Avatar). Suffolk breed rams were found to have (p ≤ 0.05) the lowest weight at slaughter (37.47 ± 4.10 kg) and also carcass weight (15.23 ± 1.78 kg). Romney Marsh's carcasses had a significantly higher degree of fat cover (3.6 ± 0.4), kidney fat ratio was 0.78 ± 0.17 % and the percentage of fat from the right leg was 2.50 ± 0.61 %. The conclusively (p ≤ 0.01) highest ratio of the right leg was recorded in the Suffolk breed (17.00 ± 0.79 %). The highest ratio of the leg of carcass among the lines was found in the President line (17.53 ± 0.66 %). Meat of the Suffolk line had the significantly (p ≤ 0.01) highest ratio of dry matter, intramuscular fat, protein and ash. Among the lines, this trend was similar in favor of the Suffolk's line. The Zwartbles breed had the lowest (p ≤ 0.01) ratio of fat and dry matter in the meat. The value of pH, lightness (L* = 51.55 ± 1.66) and color spectrum b* (13.12 ± 0.46) of meat was conclusively (p ≤ 0.01) the highest in the Zwartbles breed, while the redness indicator (7.56 ± 1.45) was conclusively the lowest for this breed. Statistically (p ≤ 0.01), the meat of the Suffolk breed had the most potent red color (a* = 11.87 ± 1.24) and the highest water-holding capacity (81.57 ± 1.87).
