A combination of garlic oil and cooked chilli oil could be effective and efficient for pigeon production

Abstract

This study was conducted to investigate whether the combination of garlic oil and cooked chilli oil is worth using for pigeon production in the context of a total ban on antibiotics in feed additives in China. Two hundred female white king pigeons aged 23 days were randomly divided into five groups with ten replicates (four birds each). In the 47 days trial, the control group was fed with a basal diet, treatment groups were given a basal diet supplemented with 20 mg/kg neomycin sulphate or 2 g/kg corresponding oil (garlic oil or cooked chilli oil or their mixture) respectively. The mixed oil showed obvious antibacterial activity against gram‐positive bacterium and its minimal bactericidal concentration against St. aureus, Salmonella and Escherichia coli were all no more than 1.0 mg/ml. In the feeding experiment, pigeons feed with garlic oil with strong bacteriostatic activity had lower FCR and better protein metabolism, and chilli oil showed strong effects of promoting feed intake and weight gain on pigeons but increased serum glucose and lipid content. Compared with the control and the antibiotic group, the mixed oil got increased growth performance, less drip loss of meat, better protein metabolism promoting, and more complete intestinal structure of pigeon. In addition, the breast meat in the mixed oil group had higher total points in the sensory test. The mixed oil combined the strong bacteriostasis of garlic oil with the feeding promotion effect of cooked chilli oil, it improved the comprehensive performance of pigeons and had the feasibility to be popularized as a non‐antibiotic strategy in pigeon production.

Determination of Antibacterial Activity of St. John's Wort (Hypericum perforatum L.) Oil, Nigella Sativa Oil, Clove (Eugenia caryophyllata) Oil, Orange Peel (Citrus sinensis) and Garlic (Allium sativa) Oil Against Microorganisms Isolated From Clinical Samples

“…Gentamicin (10 μg/mL) was used as a positive. Zone diameters were measured after 24 hours of incubation [20][21][22][23][24] .…”

“…The last well without growth was determined as the Minimum Inhibition Concentration (MIC) value. The antibacterial effect of plant extracts was tested by minimum inhibitor concentrations (MIC) against ten control bacterial strains Gentamicin was used to control the study [20][21][22][23][24] .…”
