Effect of Using Garlic on the Economical and Physiological Characteristics of Broiler Chickens

Abstract

The aim of this investigation was to evaluate the beneficial effects of garlic powder as a phytogenic supplement on broilers chickens' performance. The assumption that garlic could improve some economic and performance characteristics of broiler chickens (i.e. body weight, feed intake, water intake, feed conversion ratio, feeding cost, carcass yield and mortality rate) was tested. A total of 400 one-day-old chicks of mixed sex (Hybrid) were weighed and randomly assigned to four treatment groups, each with 4 replicate pens of 25 chicks. The dietary treatments included the basal diet (control), control + 2.5 kg /ton Garlic, or control + 5 kg /ton Garlic or 7.5 kg /ton Garlic as powder. The results of the study revealed that incorporation of garlic powder in broiler diets as feed additive significantly enhanced growth, economic and productive performance of these chickens. Physiological measurements (body weight, weight gains, feed intake, feed conversion ratio, carcass weight and internal organs) showed better performance of garlic treated chickens compared with control group under same rearing system. The results similarly showed lower susceptibility to diseases and medicament treatment consequently; lower mortality rate compared to control groups. Furthermore, blood and meat analysis showed lower cholesterol, Triglyceride, LDL, and, HDL levels compared with control group. The study concluded that Garlic can be effectively used in broilers feeding to replace antibiotic as growth promoter.

Effect of Supplementation Garlic (Allium sativum) by Various Processing on Performances of Broiler

“…These findings are consistent with those of [19]. Similarly, when comparing the birds-fed garlic powder diets to the control group, [7] found that feed intake was considerably (P<0.05) more excellent in the birds-provided garlic powder diets. Garlic powder supplementation enhances feed intake, most likely due to the associated flavor element.…”

“…Allicin can be used as a natural antibiotic since it is more effective than penicillin and tetracycline at eliminating pathogenic bacteria [6]. Garlic has been utilized to promote growth by improving poultry performance [7].…”

Supplementing Garlic Nanohydrogel Optimized Growth, Gastrointestinal Integrity and Economics and Ameliorated Necrotic Enteritis in Broiler Chickens Using a Clostridium perfringens Challenge Model

“…A previous study showed that supplementation of garlic to broilers' diets improved their immune systems and digestion efficiency due to the abundance of bioactive compounds of garlic, namely, alliin, daily lsulphide and allicin [41]. Additionally, improvement in weight gain and better FCR of broiler chickens following the dietary supplementation of garlic can be attributed to allicin-active ingredients that promote the beneficial microflora in the gut, thereby improving the digestion efficiency and enhancing the energy utilization [42,43]. Peinado et al [44] found that the compounds obtained from garlic had increased digestibility and activities of intestinal mucosal enzymes, confirming their application as alternatives to antibiotics in broiler nutrition.…”

Effect of Feed Additives Supplementation on the Growth Performance, Gastrointestinal Tract Characteristics, and Carcass Composition in Turkey Hens

“…However, the antibacterial activity of garlic essential oil on Gram-positive bacteria ( Listeria innocua and Staphylococcus aureus ) was much higher than that of Gram-negative bacteria ( Escherichia coli and Pseudomonas aeruginosa ) [ 44 ]. Studies by Massad et al [ 45 ] and Gbenda et al [ 46 ] recorded a favourable effect of the garlic extract preparation on the birds’ weight gain and fattening grade. An improved weight gain and carcass quality and decreased mortality rates of slaughtered chickens after using a garlic preparation in the amount of 1–2.25 mL/kg feed were corroborated by Brzóska [ 40 ].…”
