- Abstract
The experiment was to study the effect of plant essential oil and propolis extract compound on growth performance, slaughter performance and meat quality of white feather broilers. 960 one-day-old white feather broilers were selected and randomly divided into four groups, with 12 replicates in each group and 20 replicates in each group. The broilers in control group (group A) were fed with basal diet, the broilers in experimental group (group B, group C and group D) were fed with basal diets supplemented with 100, 200 and 300 g/t complex of plant essential oil and propolis extract, respectively. The experiment period was 42 d. The results showed that compared with control group, EPI index of broilers in group D was significantly increased (P<0.05), the value of broilers in group B and group C was increased, but the difference was not significant (P>0.05). Compared with control group, the slaughter percentage of broilers in group C and group D was significantly increased (P<0.05), the abdominal fat percentage was significantly decreased (P<0.05), eviscerated rate of broilers in group D was significantly increased (P<0.05), and liver fat rate was significantly decreased (P<0.05). The fat and protein content in breast muscle of broilers in group D were significantly increased (P<0.05), and the cooking loss in leg muscle was significantly decreased (P<0.05). The experiment indicates that plant essential oil and compound propolis extract as white broilers feed additive can obviously improve the EPI value chamber, slaughter rate and total net rate, decrease the rate of abdominal fat and liver fat rate, improve broilers breast meat protein content and fat content, reduce the cooking loss of meat broilers legs, can significantly improve enwrapped broilers growth performance, slaughter performance and meat quality.
