Effect of emulsifier-based lipid and calcium silicate on chicken broiler productivity, digestive processes and meat quality

The feeding test was performed on 1-35 days old broiler chickens line combination ROSS 308. 750 broiler chickens were divided into three groups of 250 chickens in each group with five replicates of each group. The first group is the control group and the rest are the subject research groups. From day 1 to day 35, the chickens were fed a standard compound feed (control group) supplemented with different emulsifiers: 0.05 %. „Lysoforte Extend“(I experimental group), 0.05 %. „Lipidol Ultra“(II experimental group).Analysed fed of groups supplemented with different emulsifiers: 0.05 %. „Lysoforte Extend“ and 0.05 %. „Lipidol Ultra“ feed had no significant effect on the weight of broiler chickens. Conversion of feeding for both tests groups were increased by 4-5 %. The conservation of broiler chickens during the whole trial period was 99.2 – 99.6 %. Dry matter of litter of both tests groups was increased (p>0.05). Meat loss in boiled chicken breasts decreased I experimental group 4.41 % (p>0.05) and II experimental group 5.43 % (p>0.05), luminosity of meat decreased by 5.61 (p0.05). I subject group chicken thighs kept 3 months in -180C resulted in increase of capric acid concentration by 0.24% (p0.05) and II research group resulted with decrease of 0.23 μmol/kg (p>0.05). After 3 months of keeping II subject research group the amount of MDA increased by 0,8 μmol/kg (p>0.05). MDA in chicken broiler thighs of I subject research group decreased by 0.12 μmol/kg (p>0.05) and after 3 months MDA amount in chicken tighs dereased from 0.19 μmol/kg(p>0.05) in I subject research group to 0.23 μmol/kg (p0.05), although in the chicken thigh of II subject research group it was 15% (p>0.05) larger comparing with control group indicators
