Background & Aim: Medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.This experiment was conducted to investigate the effects of milk thistle (MT) and thyme seeds (TS) on the performance in broilers. Experimental: In this study, 160 one-day-old (Ross 308) male broiler chicks were divided randomly into four major groups with 4 replicates b...

this study was conducted to evaluate the relative bioavailability value of mn proteinate and mn oxide in broiler chicks. a total of 432 day-old cobb 500 commercial male broiler chicks were randomly distributed into nine treatments with eight replicate pens of six chicks each. in a completely randomized design experiment with a 2×4 factorial arrangement of two manganese sources (proteinate and r...

The aim of this study was to investigate the effect of commercial herbal and chemical medicines on growth performance, serum lipids, intestinal selected bacterial population and intestinal morphology of broiler chickens. In this study, 450 day-old female broiler chickens (Arian strain) were divided into 10 treatments with three replicates of 15 chicks per replicate. On day 14 of the experiment,...

This study was conducted to investigate the effect of supplementation different levels of pomegranate seed pulp (PSP) on performance and blood parameters in laying hens. A total of 96 layers hens (Hy-line W-36) at 24 week of age were randomly assigned into 4 treatments including 0 (control), 5, 10 and 15% of PSP, with 4 replicates containing 6 layers in each. Results showed no significant effec...

this study was carried out to investigate the effects of medicinal plants, prebiotic and probiotic as alternatives to antibiotics on the growth performance, intestinal morphology and ileal digestibility of nutrients in broilers. a total of 288 one- day-old broiler chicks (cobb 500) were randomly assigned to 6 treatments and 4 replicates with 12 chicks per each replicate in a completely randomiz...

An experiment was conducted to study the effects of an emulsifier (glycerol polyethylene glycol ricinoleate: GPGR) and different sources of fat on the performance of Khaki Campbell ducks. Ducks were assigned into five groups with three replicates (10 ducks/replicate) in each group. Treatments were a control diet (C1: without added oil and emulsifier), control diet added with 2% soybean oil (C2)...

Forty growing ram lambs (Lori-Bakhtiari breed) averaging 28 kg (±1.5) were allocated in this study to evaluate the optimal dietary energy density in a lamb fattening enterprise in Iran. The feed intake (FI), body weight (BW), gain to feed ratio (G:F) and carcass characteristics were studied. Four treatments differed in metabolizable energy content (ME) as follow; 2, 2.3, 2.6 and 2.9 Mcal/kg for...
