The effect of different levels of propolis in diets on performance, gastrointestinal morphology and some blood parameters in broiler chickens

Abstract

SummaryShaddel-Tili, A., B. Eshratkhan, H. Kouzehgari & M. Ghasemi-Sadabadi, 2017. The effect of different levels of propolis in diets on performance, gastrointestinal morphology and some blood parameters in broiler chickens. Bulg. J. Vet. Med., 20, No 3,[215][216][217][218][219][220][221][222][223][224] A study was conducted to determine the effect of different levels of propolis in diets on performance, carcass characteristics, gastrointestinal morphology and some blood parameters in broiler chickens. A total of 224 one day-old Ross 308 chicks were randomly allocated to one of the 16 floor pens in a completely randomised design (four treatments, four replicate groups, 14 chicks in each group). Dietary treatments consisted of 4 different levels of propolis powder including zero (control), 500, 1500, 2000 ppm in the diet throughout the entire experimental period (42 days). The feed was offered ad libitum. All the chickens were grown up in the same environmental and management conditions. Body weight gain, food intake and feed conversion ratio were measured at the end of each period, also, the production index was calculated at 42 days of age. At the end of experimental period, two chicks from each pen were selected and after blood sample collection were slaughtered and dissected manually. Haematological and biochemical parameters as well as carcass characteristics, gastrointestinal morphology were determined. The use of 2000 parts per million propolis powder in diet improved body weight gain, feed intake, feed conversion ratio and production index at all experimental periods (P<0.05). High dietary levels of propolis powder in diets increased the relative weight of crop, thighs and length of gizzard compared to other treatments, and decreased the relative weight of livers of broiler chickens (P<0.05). PCV and heterophil counts were significantly increased (P<0.05). It is suggested that the supplementation of propolis powder to poultry diets had a positive effect on growth performance, carcass characteristics and blood parameters.

Recent Advances in Role of Propolis as Natural Additive in Poultry Nutrition

“…10, 0. 15, 0.20, 0.25, 0.5, 1.5 and 2.0 g/kg diet (Shalmany & Shivazad, 2006;Shaddel-Tili et al, 2016). Similar results have been reported in other poultry species.…”

“…Similarly, Çetin et al (2010) documented a slight increase in haematocrit and haemoglobin values in laying hens receiving 3.0 g/kg of propolis. In broiler chicken, packed cell volume and heterophil counts significantly increased at a dose of 2.0 g propolis/kg diet (Shaddel-Tili et al, 2016). Abdel-Rahman & Mosaad (2013) found that ducks fed propolis diets had much higher haemoglobin con-centrations than the control, but the packed cell volume was not affected.…”

Single or combined effects of dietary supplemental vitamin C and ethanol extracts of propolis on productive traits, egg quality and some blood biochemical parameters of laying hens

“…Flavonoids are one of the components which are known to be responsible for the biological activities of propolis (Galal et al 2008). Propolis may exert multiple positive effects on human and animal health (Shaddel-Tili et al 2017). Besides, immunomodulatory effects of propolis have been determined (Burdock 1998).…”

The Use 3 of Banana Peel Meal (Musa paradisiaca) as Substitution of Corn in the Diets on Performance and Carcass Production of Hybrid Ducks

“…The process of absorption that occurs in the body of the livestock is influenced by the age, so that the feed given to livestock should be adjusted to the age of the livestock. The use of different feed ingredients with certain treatments causes differences in body weight gain in broiler chickens (Shaddel-Tili et al, 2016).…”
