an experiment was carried out to estimate growth parameters of broiler chickens received artichoke extract in their drinking water using gompertz non-linear model and to compare gompertz non-linear regression equation and artificial neural network modeling in terms of their ability to predict body weight of broiler chicks at day 42 of age. a total number of 250 one- day- old ross 308 broiler ch...

effects of post-hatch fasting (phf) and subcutaneous injection of ca-gluconate (ca-g) on productive performance, immune response and mortality of broiler chicks were investigated using 640 one-day-old ross 308 chicks in a 5×2 factorial experiment with five phf levels (zero, 12, 24, 36 and 48 h) and two ca-g injection levels (zero and 0.7 ml) in a completely randomized block design in four repli...

the current study was conducted to evaluate effects of sequential or wet feeding programs subsequent to and early meal feeding regime on performance, carcass characteristics and humoral immunity in broiler chicks. 192 ross 308 chicks (seven-day old) were allocated to four treatments at four replicates (12 chicks per plot) based on a completely randomized design. treatments were included: contro...

in order to investigate antioxidant and antimicrobial effects of pomegranate peel powder (ppp), this research was conducted as completely randomized design arranged in a 2 × 2 factorial experiment using pomegranate peel powder (0 and 2 percent) and soybean oil (so, zero and six percent in growing period; zero and eight percent in finishing period). one hundred and sixty 11-day-old ross 308 broi...

The experiment was performed with a total of 180 day-old, ROSS 308 combination, meat-type hybrid chickens that were divided according to sex into the control group (C1 and C2 with 30 and 30 , respectively) and two experimental groups: GLY-P1 and P2 with pure glycerol (30 and 30 ), and GLY-R1 and R2 with raw glycerol (30 and 30 ). The chickens received three feeding mixtures during the experimen...

This study was conducted to evaluate the relative bioavailability (RBV) of 25-hydroxycholecalciferol (25-OH-D3) to cholecalciferol (vitamin D3) in 1- to 21-d-old broiler chickens fed with calcium (Ca)- and phosphorus (P)-deficient diets. On the day of hatch, 450 female Ross 308 broiler chickens were assigned to nine treatments, with five replicates of ten birds each. The basal diet contained 0....

This study was organized to examine the effects of use rainwater lost from roofs as water source for broilers on performance and some basic carcass meat quality parameters.
 In research, day old 96 Ross 308 broiler chicks were used. experiment, birds separated two treatment groups given distributed 4 pens under-ground kept in other research house. Performance criteria analyzed with mixed g...

Little is known about the ranging behaviour of chickens. Understanding ranging behaviour is required to improve management and shed and range design to ensure optimal ranging opportunities. Using Radio Frequency Identification technology, we tracked 300 individual broiler chickens in each of four mixed sex ROSS 308 flocks on one commercial farm across two seasons. Ranging behaviour was tracked ...

The goal of this study was to investigate the effects Lactobacillus plantarum (L. plantarum) supplementation on growth performance, nutrient digestibility, gas emission, excreta microbiota, and meat quality in broilers. A total two hundred eighty-eight, one-day-old Ross-308 chicks (mixed sex) were randomly allocated one treatments with eight replicated cages (18 per cage). For a period 35 days,...
