Microencapsulated carvacrol and cinnamaldehyde replace growth-promoting antibiotics: Effect on performance and meat quality in broiler chickens

Abstract

The aim was to evaluate the use of mixture of microencapsulated carvacrol and cinnamaldehyde as a replacement for growth-promoting antibiotics in broiler diets on performance, intestinal quality, organ development, carcass yields and cuts, and meat quality. In the trial were used 600 male chicks, allocated in a completely randomized design, with fi ve treatments and eight replicates of 15 birds, reared up to 41 days of age. The treatments were: Negative Control (NC), Positive Control (PC) 30 mg/kg of virginiamycin, NC+100 mg/kg of essential oils, NC+200 mg/kg of essential oils and NC+400 mg/kg of essential oils. Essential oils were composed by a micro-encapsulated blend, with of 60% cinnamaldehyde, 30% carvacrol and 10% carrier. Birds received essential oils achieved performance equivalent to those birds received PC diets, having better development than NC broilers. No differences were found on relative organ weight, intestinal mucosa and meat quality parameters, however, higher villus:cript ratio was found in PC, NC+200 and NC+400 groups. Meat crude protein and yellowness were infl uenced by inclusion of carvacrol and cinnamaldehyde. It was concluded microencapsulated carvacrol and cinnamaldehyde can replace growth-promoting antibiotic in broiler diets, ensuring performance, intestinal integrity and broiler meat quality.

The TRPA1 Agonist Cinnamaldehyde Induces the Secretion of HCO3− by the Porcine Colon

“…As outlined in the introduction, TRPA1 agonists are emerging as promising pharmacological tools in the modulation of intestinal function in health and disease [ 20 , 32 ]. Despite this, only a handful of studies have systematically investigated the interaction of TPRA1 agonists with native gastrointestinal epithelia [ 14 , 16 , 39 , 45 ].…”

“…In farm animals, modulators of TRP channels in general and of TRPA1 in particular are increasingly being added to the feed of livestock as an alternative to antibiotic growth enhancers [ 31 , 32 ]. This is particularly important during weaning, during which young animals that have previously obtained readily digestible milk from their mothers are switched to diets rich in plant fiber.…”

Thymol and carvacrol supplementation in poultry health and performance

“…Bossetti et al. ( 2020 ) obtained the pH between 5.84 and 5.98 at 4 h after slaughter, explaining the values slightly above the desired parameters. pH values after 24 h of slaughter above 6.2 can be indicative of dark, firm, dry meat due to the retention of large amounts of water, affecting shelf life.…”

“…Bosetti et al. ( 2020 ) represented that the inclusion of carvacrol in broiler diets did not influence the lightness parameters and the redness of the chicken meat; however, chickens that received 100 and 200‐mg/kg essential oils differed from the others, presenting higher yellowness. This higher value observed breast meat may be explained by the greater body development of the chickens; however, this compromises the aesthetic quality of the marketed product (Kuttappan et al., 2013 ) and may also be related to a myopathy called white striping.…”

Avaliação da utilização de fitogênicos em combinação ou não com leveduras em substituição a antibióticos para frangos de corte

“…A primeira alternativa a ser proposta na presente pesquisa é a utilização de moléculas fitogênicas, oriundas do orégano (carvacrol) e da canela (cinnamaldeído), todas com ampla descrição na literatura dos seus efeitos antimicrobianos (Bosetti et al, 2020). Adicionalmente, outra alternativa disponível e com efeitos semelhantes aos promotores de crescimento é adição de leveduras nos alimentos.…”
