Efficacy of Tulsi (Ocimum Sanctum) Plant Powder on Health, Growth and Carcass Traits of Japanese Quail (Coturnix Japonica)

Modulation of growth performance, gut morphometry, and cecal microbiota in broilers by clove (Syzygium aromaticum) and tulsi (Ocimum sanctum) supplementation

“…We also observed an improved feed conversion ratio in the treatment groups where clove and tulsi were supplemented at 0.5 to 1% and 2 to 3%, respectively. This finding is similar to the previous reports ( Cabuk et al., 2014 ; Al-Mufarrej et al, 2019 ; Arif et al, 2022 ; Naeem et al, 2022 ). Clove has potential antimicrobial and antioxidant properties ( Batiha et al, 2020 ).…”

“…However, the level of feed intake is quite dose-dependent as the feed intake was found to be decreased at the higher dose of clove (1.5%) and tulsi (4%). A similar finding was also reported in some of the previous studies ( Mustafa, 2016 ; Al-Mufarrej et al, 2019 ; Naeem et al, 2022 ). The reduced feed intake at the high dose of clove (1.5%) and tulsi (4%) might be due to the reduced palatability because of the presence of a high amount of eugenol which decreases gut motility ( Daniel et al, 2009 ).…”

“…The body weight gain in the experimental broilers showed a linear relationship with feed consumption. Clove and tulsi are frequently used as growth promoters ( Agostini et al, 2012 ; Naeem et al, 2022 ). Dietary supplementation of clove oil to the broilers improves their weight gain ( Mustafa, 2016 ).…”

“…This finding is similar to Al-Mufarrej et al (2019) , who reported a gradual decrease in body weight gain when the dose of clove is 2% or more. Supplementation of 0.5 to 1.5% tulsi increases feed intake, body weight gain, and ultimately the growth performance of poultry ( Vasanthakumar et al 2013 ; Naeem et al, 2022 ). Clove buds comprise a high amount of saponin ( Chaudhary et al, 2018 ).…”
