Effect of supplementation of Satureja essential oils in drinking water on immune performance of broiler chickens reared under heat stress

Abstract

Phytogenic feed additives, also called as phytobiotics or botanicals, are plant-derived compounds added into diets to enhance the productivity of poultry. This study was conducted to investigate the effect of administration of Satureja khuzestanica essential oils (SKEO) through drinking water on immune performance of broiler chicken using 720 one-day-old Arian chicks. The birds were raised under standard production practices up to 42 days of age. The birds continuously received drinking water treated with Tween 80 (Cont+; 500 ppm) or SKEO at 0 (Cont-), 200, 300, 400 and 500 ppm. The mean hemagglutinin inhibition (HI) antibody titer was not significantly different among the treatments at 15, 21, 28 and 35 days of age (P>0.05). No significant differences were pointed out for relative weight of spleen, bursa and thymus at 21 days. Thymus weight reduced for the birds that received treated water but a difference was only significant for 400 ppm SKEO. The mean hetrophyle lymphocyte ratio was not significantly differing among the treatments. It is concluded that supplementation of broiler chicken drinking water with S. khuzestanica essential oils has no favorite impact on immune response of heat stressed broiler chicken.

Effects of oral administration of various essential oils on blood metabolites, intestine development, microbial enumeration and meat quality in broilers

“…In other studies, aldehydes extracted from essential oils suppressed TNF-α secretions in mice (Chao et al, 2008), and the essential oils of Cryptomeria japonica and Artemisia fukudo had a similar suppressive result (Yoon et al,2009;Yoon et al, 2010), which is in line with the results of the present study that carvacrol, thyme, or oregano, to some degree, inhibited TNF-α secretion, but not statistically significant (P>0.05). In short, essential oils improved immunity to a certain degree in the present study, in agreement with previous research (Parvar et al, 2013). It could be that the essential oils have an anti-inflammatory effect.…”

Effect of the addition of essential fatty acid mixture to the drinking water of the heat stress broilers on adipokine (Apelin, BDNF) response, histopathologic findings in liver and intestines, and some blood parameters

“…In the studies made on the effects of EOM (Eucalyptus globulus Labill, Thymus vulgaris, Cymbopogon nardus ve Syzgium aromaticum) mixture on the plants, they were reported to have antioxidant (Vollmayr et al 2001), anti-microbial (Karpouhtsis et al 1998;Dorman and Deans 2000;Ultee et al 2002), antiinflammatory (Bishop 1995;Guimarães et al 2013), anti-viral (Al-Ja'fari et al, 2011Silva et al 2011), antitumoral (Al-Ja'fari et al, 2011, anti-fungal (Fu et al 2007;Monzote et al 2007), antiparasitic (Chowdhury et al 2018) and positive effects on growth performance by having effects on intestinal villuses via digestional enzymes (Jang et al 2007). In addition, positive effects of Essantial oil supplementation in broiler chickens exposed to heat stress has been confirmed by other authors (Parvar et al, 2013;Gopi et al, 2014;Akbarian et al 2015;Petrolli et al, 2019).…”

Effect of Pidotimod, Astragalus and Eachnicea on Immune Response and Growth Performance of Broiler Chicks

“…Thus, led to a significant increase in the humoral antibody titers against the ND virus, they activate the immune system [60]. On the other hand, the phytobiotic failed to create a significant improvement in the humeral immunity of broiler chicks [61][62][63].…”
