Summary An experiment was conducted to examine the effect of microbial phytase associated with different nonphytate phosphorus (NPP) levels on performance and egg quality parameters of laying quails from 8-16 weeks of age. A total of 196 Japanese...... Mehr Effects of different angled perches on leg disorders in broilers Summary Perching behavior is common in birds, however, perches are not provided in commercial broiler flocks. The main purpose of this study was to determine the relationship between incidence of leg deformations and various perch uses in litterand...... Mehr Effect of treated field pea ( Pisum sativum L. cv Spirale ) as substitute for soybean extracted meal in a wheat middlings-based diet on egg production and quality of early laying brown hens Summary This study was designed to establish the effect on laying performance and egg quality resulting from substitution of soybean meal with dehulled-micronized peas ( L. cv Spirale ) in the diet of early phase brown laying hens. Isa Brown...... Mehr Stunning effectiveness of broiler chickens using a two-phase stunner: pulsed direct current followed by sine wave alternating current Summary Stunning efficiency of male and female broiler chickens was analysed in response to the two-phase Simmons step-up stunner. In Phase I, a pulsed DC of 550 Hz is appliedin a shallow waterbath. This is immediately followed by Phase II,...... Mehr Fractional apoB-VLDL hepatic synthesis rate in Muscovy and Pekin ducks fed ad libitum Summary Muscovy duck has a higher ability to develop hepatic steatosis than Pekin duck. This could result from a lower ability of liver to secrete lipids and lipoproteins. To test this hypothesis, we measured the liver apoB-VLDL secretion in...... Mehr Effects of dietary energy density and coarsely ground maize supplementation on growth performance, carcass traits and meat quality of capons Summary This research study was carried out to evaluate the effects of feeding diets containing two levels of metabolizable energy and the effects of adding ground maize in the last month of fattening on capon growth and carcass characteristics....... Mehr Effects of Euphorbia hirta and virginiamycin supplementation tothe diet on performance, digestibility, and intestinal microflora population in broiler chickens Summary This experiment was conducted to investigate the effects of supplementing various dosages of powderon performance, digestibility, and ileal microflora populationin broiler chickens. E. hirta was supplemented at inclusion rates of 2.5...... Mehr Experimental studies on the effects of different litter moisture contents and exposure time to wet litter on development and severity of foot pad dermatitis in young fattening turkeys Summary This experimental study aimed to find out the critical moisture content of litter which results in higher development and severity of FPD in young fattening turkeys. Four groups of two weeks old ♀ turkeys were reared on dry wood...... Mehr A proposal to apply operative temperature for the evaluation of thermal conditions in the broiler living zone Summary The paper presents results of temperature measurements at the level of birds’ heads, at the level of bedding under the birds, and in areas not occupied by birds, as well as measurements of optimal air temperature and the distribution of the...... Mehr Relationships between feather score and egg production and feed consumption of different layer hybrids kept in conventional cages Summary This study assessed feather scores, egg production and feed consumption of three local and two imported layer breeds. The relationships between feather score and egg production and feed consumption were evaluated for the total study...... Mehr Egg quality of three laying hen genotypes kept in conventional cages and on litter Summary The effects of housing system (conventional cages, litter), genotype (ISA Brown, Hisex Brown and Moravia BSL) and age on egg quality parameters were evaluated. Eggs were sampled three times in the laying period at the age 20 to 24 weeks, 38...... Mehr
