Evaluation of the effect of breed and line on slaughter value and quality of lamb meat

Original language description

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 LESS-THAN OR EQUAL TO 0.05) the lowest weight at slaughter (37.47 +- 4.10 kg) and also carcass weight (15.23 +- 1.78 kg). Romney Marsh&apos;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 LESS-THAN OR EQUAL TO 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 LESS-THAN OR EQUAL TO 0.01) highest ratio of dry matter, intramuscular fat, protein and ash. Among the lines, this trend was similar in favor of the Suffolk&apos;s line. The Zwartbles breed had the lowest (p LESS-THAN OR EQUAL TO 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 LESS-THAN OR EQUAL TO 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 LESS-THAN OR EQUAL TO 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).
