Effects of dried Portulaca oleracea supplementation to the laying hen diet on productive performance, egg physical traits, fatty acid composition, and cholesterol content | Antonella Dalle Zotte, Gianluca Pranzo Agricultural Journals

This study was to investigate the relationship between chick weight in growing period and laying performance of Korean native chicken (KNC) breeders. We measured body weights 1,384 KNC breeders at 1-140 days age two-week intervals. The first egg laying, hen-day hen-housed production, were investigated. Correlation coefficients production traits analyzed. results showed that correlation signific...

in this experiment, the effects of fennel and thyme extracts with and without flaxseed were investigated on performance and egg quality of leghorn-type laying hens (hy-line w-36). 200 laying hens from 26 to 38 weeks of age were assigned to five dietary treatments with five replications. the treatment groups were: 1) control (a diet without any additives); 2) control diet plus fennel (40 mg/kg f...

this study aimed to decrease the cholesterol content of egg yolk of laying hens through inclusion of barley malt rootlets in the diets. forty-two, 54-week-old, lohman laying hens were fed for a 12 weeks laying period on 3 iso-caloric and iso-nitrogenous diets contained 0 (control), 25.5 or 51.1g barley malt rootlets/kg. inclusion of barley malt rootlets at 25.5 or 51.1g/kg diet significantly de...

the effect of yeast culture (saccharomyces cerevisiae) supplementation on laying hen diets was tested against flavomycin supplementation during 12 weeks, using 112 brown bovans laying hens, 52 week-old, divided into 7 equal groups fed on a basal diet containing 18.8% crude protein and 2810 kcal/kg me (metabolizable energy) feed. three groups were supplemented with 3 different levels of commerci...

Optimization of carnosine and anserine extraction from chicken breast was performed using response surface methodology (RSM) to obtain the maximized physiological activities for anti-glycation and anti-oxidation. The optimum extraction conditions were water extraction for 1.6 h in the case of the 20-wk laying hen muscle and water extraction for 2.12 h in the case of 90-wk laying hen muscle. Hig...

The objective of the present study is to research the effect of dietary vitamin E (Vit E) on laying performance, lipid peroxidation and antioxidative status in laying hens under experimentally induced oxidative stress conditions via Dexamethasone (DEX) administration. A total of 60 Egyptian local strain (Gimmizah) laying hens at 36 weeks of age were housed in individual cages in an open-sided b...

a study was conducted to evaluate the effects of two laying systems (floor versus cage) on egg production, egg quality, and microbial safety. one hundred and eighty 42 wk old laying hens were separated into two groups of 90 hens each, and housed in laying cages and a floor laying system. eggs from the hens were collected for 2 weeks, and hen-day egg production, egg quality (whole egg, albumen, ...
