This study examined the effect of rapid cooling with air and CO2 on shell egg quality over 14 wk. The 240 fresh eggs were initially heated to 47 C for 24 h in an incubator, cooled using rapid air cooling or CO2 cooling, and then stored in air or CO2 in 250-mL jars for 14 wk. The CO2 levels were recorded of the jar atmosphere, of the egg air cell, and of the egg albumen. The Haugh units of each ...

In a 2  3  2 factorial arrangement, 144, fifty–four-week-old laying hens, in 12 treatments with 12 replicates for each treatment, received one of 12 diets based on maize or wheat containing three levels of dried tomato pomace (DTP: 0, 50 and 100 g/kg) as a substitute for wheat bran, and two levels of pigment (0 and 900 mg/kg), for 9 weeks. Weight gain (WG), egg production (EP), egg weight (EW...

in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...

The aim of the study was to evaluate effects on exterior and interior egg quality and sensory characteristics of eggs from hens fed diets with admixtures of 3.5 or 7.0% of mussel meal or 20% wheat-distillers dried grains with solubles (DDGS). The mussel meal diets followed organic standards, whereas the DDGS diet was formulated for hens in conventional production. Standard diets, one organic an...
