Piperine as a phytogenic additive in broiler diets

Abstract

-The objective of this work was to determine the effect of piperine as a phytogenic additive in chicken broiler diet. Seven-day-old male chicks were randomly allocated in four experimental treatments (n = 24), with four replicates (n = 6). The piperine was added to diets at concentrations of 0, 60, 120, and 180 mg kg -1 for 35 consecutive days. The following were evaluated: biochemical, hematological and histopathological parameters; performance and carcass yield. Histomorphometric analyses were also carried out. The addition of 120 and 180 mg kg -1 of piperine did not alter broiler body weight and feed conversion, whereas 60 mg kg -1 of piperine interfered positively in both parameters from 36 to 42 days of age and significantly increased the absorption surface of the duodenum and the ileum. No macroscopic alteration in organ size and color was observed in the broilers fed diets with the evaluated concentrations of piperine. The supplementation of 120 and 180 mg kg -1 of piperine is toxic to liver tissue and reduces the absorption surface of the jejune. The diet supplemented with 60 mg kg -1 of piperine is safe.Index terms: Piper nigrum, performance, phytogenic additive, sanitation. Piperina como suplemento fitogênico na dieta de frangos de corteResumo -O objetivo deste trabalho foi determinar o efeito da piperina, como suplemento fitogênico, na dieta de frangos de corte. Pintos com sete dias de idade foram distribuídos aleatoriamente em quatro tratamentos (n = 24), com quatro repetições (n = 6). A piperina foi adicionada na ração nas concentrações de 0, 60, 120 e 180 mg kg

Antigenotoxic Effect of Piperine in Broiler Chickens Intoxicated with Aflatoxin B1

“…These effects were not found in animals treated with piperine [44]. Cardoso et al [31] evaluated the effect of piperine in different concentrations (60, 120, and 180 mg·kg −1 ) for 35 consecutive days and the best and least toxic concentration was 60 mg·kg −1 . …”

“…First the piperine was solubilized in soy oil and then added to the feed with the other ingredients which were described by Cardoso et al [31]. …”

“…The aflatoxin was given to broilers which were weighed daily. The doses of piperine and AFB1 used were in accordance with Cardoso et al [31,44]. …”

“…In addition, piperine may be found in all parts of the plant [26]. Recent studies have shown that the consumption of piperine is relatively safe, with low toxicity to cells of mammals and avian species [27,28,29,30,31]. Piperine has several biological and pharmacological properties, such as insecticidal [32], antiparasitic [33], antipyretic, analgesic, anti-inflammatory [34], and antioxidant activities [35,36].…”

Use of black pepper, cinnamon and turmeric as feed additives in the poultry industry

“…Kitikar and Basu (1996) reported that its rhizome can be used as a calming agent, a diuretic, a hepatoprotectant and in the treatment of urinary tract and skin diseases such as scabies, leech bites and bruises. Cardoso et al (2012) reported that in the finisher period from 36 to 42 days of age, the broilers receiving a dietary supplement with 60 mg/kg of piperine showed better weight gain and feed conversion rate (P<0.05).
