The Effects of Rosemary Extract (Rosemaria officinalis) as a Feed Additive on Growth and Whole-body Composition of the African Catfish (Clarias gariepinus (Burchell, 1822))

Abstract

A preliminary study was conducted to evaluate the effect of the Rosemary extract (Rosemaria officinalis) on growth performance, feed utilization and body composition of the African catfish (Clarias gariepinus, Burchell, 1822). Fish with an average body weight of 10.59±0.31 g were fed with different concentrations (0, 0.25 and 0.5 %) of Rosemary extract at dietary for 60 days. At the end of experiment, the highest values of weight gain, specific growth rate and food conversion rate were 17.23±0.08 g, 1.93±0.07 and 1.16±0.06 at 0.5% Rosemary extract dosage group respectively. The highest survival rates were 100% at 0.25% Rosemary extract dosage groups. No significant differences were shown in whole body protein and lipid content among the dietary treatments. These results indicate that treatment of Rosemary extract has positive effect on growth in African catfish with no apparent effects on health status.

Effects of rosemary extract supplementation in feed on growth performance, meat quality, serum biochemistry, antioxidant capacity, and immune function of meat ducks

“…Because rosemary is a common, available, and non-toxic herb, RE shows great potential as food and animal feed additives ( Oluwatuyi et al, 2004 ). Previous papers showed inconsistent effects of dietary RE on animals’ growth performances depending on animal species and concentrations of RE supplementations ( Turan and Yiğitarslan, 2016 ; Yildirim et al, 2018 ). Nonetheless, dietary RE could decrease lipid peroxidation and alleviate oxidative damage in animals, showing a solid antioxidative effect ( Yildirim et al, 2018 ; Yang et al, 2021 ).…”

“…Similary, Kıvrak and Didinen (2017) stated that rosemary oil did not positively affected on rainbow trout growth. In contrast, Turan and Yiğitaslan (2016) reported rosemary extract has positive effect on growth in African catfish with no apparent effects on health status. This difference between the findings might be due to the use different fish species in different experiments.…”

“…In the limited number of researches carried out with the aim of determining the opportunity of using plants and the active agents they contain in the cultivation, it has been reported that plant extracts added to the feed and water enhance the feed consumption, feed conversion, and growth and carcass quality (Simsek et al, 2005;Immanuel et al, 2009;Oskoii et al, 2012). Several studies have reported that oral administration of fig extract in Paralichthys olivaceus (Cho, 2011), and Paralichthys olivaceus (Lee et al, 2015) and rosemary extract in African catfish (Turan and Yiğitaslan, 2016) improved growth performance.…”

Efficacy of vitamin E with or without probiotic, astaxanthin or rosemary extract on growth performance, survival, haematological parameters, antioxidant activity and liver enzymes in rainbow trout ( Oncorhynchus mykiss )

“…Decreased values of Teri‐methylamine‐nitrogen (TMA‐N) and Total volatile base‐nitrogen (TVB‐N) have been reported in fried Escolar ( Lipidocybium flavobrunium ) fish fillet by rosemary extract, which resulted in retardation of oxidative changes in frozen fillets (Sarabi et al, 2017). Growth promotion of tilapia ( Oreochromis mossambicus ) and African catfish ( Clarias gariepinus ) fed diets containing rosemary extract have been also reported (Turan & Yiğitaslan, 2016; Yilmaz et al, 2011). These researchers suggested that such occurrence could be a result of enhancing digestibility and utilization efficiency of nutrients by dietary rosemary extract.…”
