AI Article Synopsis

  • Antibiotic growth promoters in poultry were banned due to serious side effects, leading to the exploration of leek leaf extract (LLE) as an alternative growth promoter and feed additive.
  • In a study with 250 broilers fed varying amounts of LLE for 42 days, results indicated that LLE significantly improved growth performance and carcass characteristics while positively affecting serum biochemical parameters.
  • The highest inclusion of LLE (0.2%) resulted in the best growth rates and economic benefits, increasing net profit and overall efficiency compared to control groups.

Article Abstract

Antibiotic growth promoters have been used to improve growth and feed conversion in the poultry industry for a long time; however, they were banned because of several life-threatening side effects in animals, poultry, and humans. This work was carried out to investigate the effect of leek () leaf extract (LLE) as a non-traditional growth promoter and feed additive on growth performance, carcass characteristics, serum biochemical parameters, and economic efficiency of broilers. Hubbard unsexed 1-day-old broilers ( = 250) were fed with diets supplemented with LLE for 42 days. The experimental chicks were randomly assigned to one of the five treatment groups varying in LLE quantity in diets: 0% (control), 0.05, 0.1, 0.15, and 0.2%, with five replicates per treatment (50 chicks/treatment or 10 chicks/replicate). Results showed that LLE supplementation improved ( < 0.05) different growth performance parameters. Furthermore, dietary LLE not only decreased serum total cholesterol, triglyceride, low-density lipoprotein, and glucose levels but also increased serum high-density lipoprotein level compared to the control diet. The weight percentages of dressing ( = 0.022) and liver ( = 0.041) showed a marked increase after the addition of LLE. Return, net profit, and collective efficiency measures were increased ( = 0.001) in all LLE groups compared with the control group. Broilers that fed on diets containing 0.2% LLE showed the highest growth and economic efficiency. It could be concluded that supplementation with LLE in broilers has growth-promoting effects, improved biochemical parameters, carcass quality, and promoted economic efficiency through maximizing both return and net profit.
