Summary: | The aim of this research was to investigate the production traits,
blood metabolic profile and fatty acids of meat and tallow in
response to the partial replacement of soybean meal with peas in lambs' feed. The research was conducted on 30 Merinolandschaf
lambs of 90 days' age over 30 days. Lambs were fed with feed mixture (1000 g day<sup>−1</sup> lamb<sup>−1</sup>). In the control group protein
supplement was soybean meal (SC), while in the experimental groups soybean meal was partially replaced with 13 % peas (P13) and
26 % peas (P26). In the haematological parameters of lambs' blood, concentrations of minerals (Ca, P, Mg and Fe) and
biochemical parameters (urea, glucose, total protein, albumin, globulins, cholesterol, HDL, LDL, triglyceride,
<i>β</i>-hydroxybutyrate and non-esterified fatty acids) as well as enzyme activity (ALT, AST, ALP, GGT and CK) were determined. After
slaughter, carcass development was measured. Samples of m. semimembranosus and tallow were taken in which
concentrations of fatty acids were analysed. Values of meat pH and colour were taken 45 min 24 h post mortem, and
water-holding capacity was calculated. By analysing the production properties of lamb, we found that slaughtering characteristics of lamb
carcasses, haematological and most of the biochemical indicators did not differ. Urea concentrations were reduced in the blood of
lambs in P13 and P26. Concentration of C18:2 n-6 increased in tallow of lambs of group SC compared to group P26 of lambs. The
above-mentioned results indicate the possibility of partial replacement of soybean meal with peas in lambs' diets in organic farming without
changes in production. |
