Abstract

Achkakanova, E., Penchev, I. G. & Georgieva, S. (2024). Effect of birth type on meat quality in Ile-de-France lambs. Bulg. J. Agric. Sci., 30(3), 515–522

The aim of the present study was to investigate the influence of the factor “birth type” in lambs on the performance of the meat obtained from them. The studied lambs were of the Ile de France breed and were divided into two groups: the first group is Single and the second group – Multiple. The lambs were slaughtered at 120 days of age, with 4 lambs from each group slaughtered. Samples were taken at 24 hours post mortem from the following muscles: m. longissimus thoracis et lumborum (LTL), m. iliopsoas (IP) and m. semimembranous (SM). The research of the samples for the chemical composition and technological qualities of the meat was carried out 48 h post mortem, stored at 4°C. Regarding the total chemical composition of the meat, no significant difference was observed between the two study groups. There was also no significant difference between the groups in terms of technological qualities (pH value, color, roasting losses, brittleness). Only a significant difference (p < 0.01) was found in the indicator of water-holding capacity between the groups in the studied LTL and IP muscles.
