This study was carried out to investigate the egg production performance and egg quality characteristics of the indigenous ‎chickens reared in rural areas of two different climates of Isfahan province. Totally, 2160 indigenous chickens were studied in ‎this research. Two dominant climatic regions (cold and ‎hot) were determined for Isfahan province. In each climate, two towns and three villages...

this experiment was conducted to evaluate the effect of increasing levels of alfalfa leaf meal (alm) on egg production, egg traits and blood parameters of laying hens with 144 hy-line (w36) laying hens from 65-75 weeks of age in 4 treatments, 3 replicates and 12 hens in each replicate in a completely randomized design. experimental groups included: 1) control group, 2) group with 1% of alm, 3) ...

this experiment was conducted to evaluation the effects of different levels of untreated and treated green grape leaf with urea on performance, egg quality traits and blood parameters of laying hens. in this experiment 192 hy-line (w-36) laying hens, 35 to 46 wk of age were divided in to 4 treatments with 4 replicates (12 birds per replicate) in a completely randomized design experiment. the tr...

an experiment was conducted to investigate the effects of using different levels of red pepper powder (rp) and marigold flower powder (mf) on egg production, egg yolk color andsome blood metabolites in laying hens. ninety, 103-weeks old laying hens were divided into 5 treatments groups of 6 birds in each cage with 3 replicates in a completely randomized design. the birds were fed a corn-soybean...

the present research was designed to examine the genetic analysis of egg weight, egg yolk weight and egg albumen weight of bovan neva black laying hens at 25, 51 and 72 weeks. for this purpose, thirty birds were selected from the layer flock in the babcock university teaching and research farm. they were individually housed in separate labeled battery cage. a total of thirty eggs were collected...
