Growth Performance, Carcass Characteristics and Intestinal Microflora of Broiler Chickens Fed Diets Containing Carum copticum Essential Oil
We evaluated the effects of dietary Carum copticum essential oil (CCEO) on growth performance, carcass characteristics and intestinal microflora of broiler chickens. A total of 240 Cobb broiler chickens were allocated to five dietary treatments, each with four replicates of 12 birds. Dietary treatments were prepared by formulating a corn-soybean meal-based diet free of antibiotics (Control) and...
متن کاملProductive performance and histological features of intestinal mucosa of broiler chickens fed different dietary protein levels.
To evaluate the effect of decreasing dietary protein on growth performance, carcass traits, and intestinal mucosal morphometry, 180 female Hubbard strain broiler chickens were divided into 3 groups and fed 3 isoenergetic diets ad libitum from 14 d of age until slaughter age (49 d). The treatments varied according to 3 protein levels: high-protein diet (HiP, 22.5% CP, DM basis), medium-protein d...

The study was conducted to determine the effects of dietary supplementation rosemary aromatic plant, rosemary volatile oil and α-tocopherol acetate (Vitamin E) on serum variables of broilers fed on maize-soybean meal based diets. Eight hundred 1-d-old Ross-308 male chickens were weighed and randomly divided into 1 control and 7 experimental groups each with 10 replicates of 10 birds. There were...
متن کاملGrowth performance of broiler chickens fed diets containing shea nut (Vitellaria paradoxa, Gaertn.) meal fermented with Aspergillus niger.
Shea nut meal is a by-product of the shea fat industry in West Africa. The objective was to determine the effect of shea nut meal fermentation using Aspergillus niger on growth performance of broiler chickens. An expeller shea nut meal was fermented in a closed plastic container for 8 d after the addition of 0.25 g of A. niger spores per kg of shea nut meal in 2 parts of water. Each of the 2 sh...
