this study was conducted to investigate the effect of supplementation different levels of pomegranate seed pulp (psp) on performance and blood parameters in laying hens. a total of 96 layers hens (hy-line w-36) at 24 week of age were randomly assigned into 4 treatments including 0 (control), 5, 10 and 15% of psp, with 4 replicates containing 6 layers in each. results showed no significant effec...

introduction: diagnosing and treating diseases associated with amyloid fibers remain a great challenge despite of intensive research carried out. one important approach in the development of therapeutics is the use of herbal extracts which are rich in aromatic small molecules. cinnamomum verum extract (ce) contains proanthocyanidin and cinnamaldehyde, which have been suggested to be capable of ...

A (3 x 3) factorial arrangement was used in a completely randomized design to study the effect of early nutrition of pullet on subsequent egg production and quality. Three levels of protein and three levels of energy during stages of pullet growth (starter 0-6 wk, grower 7-12 wk and developer 13-18 wk of age) and their effect on laying performance (22-36 wk of age) were evaluated. In all phases...

The objectives of this study were 1) to compute appropriate mathematical curves that describe the daily production process by the input variables daily feed consumption, water consumption, ambient temperature, and output variables hen-day egg production, egg weight, second grade eggs, floor eggs, cumulative mortality, body weight, and flock uniformity; and 2) to obtain insights into the daily v...

The egg production sector is in a transitional period with regard to the permitted housing systems, i.e. rearing conventional cages under certain conditions complete ban of any form cage system. changes were caused by concern for layer wellfare but expected effects on productivity as well. aim research was determine floor space allowance and non-cage systems feather score laying hens three ages...

As an integral part of the Coalition for Sustainable Egg Supply (CSES) Project, this study simultaneously monitored air emissions of 3 commercially operated egg production systems at the house level and associated manure storage over 2 single-cycle flocks (18 to 78 wk of age). The 3 housing systems were 1) a conventional cage house (CC) with a 200,000-hen capacity (6 hens in a cage at a stockin...

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...

Herein, we present a one pot microwave assisted facile synthesis of highly water-soluble carbon dots and explore their inhibitory effect towards amyloid fibrillation or anti-amyloidogenic properties using Hen Egg...

one hundred forty-four 26-wk-old white hy-line layers (w-36) were fed commercial diets containing 0, 1.5, 3 and 5% surplus date for three period of 28 days each to study the effects of dietary surplus date on hen performance (egg production, egg weight, egg mass, feed intake, feed conversion ratio ‘fcr’ and body weight gain) and egg quality parameters (haugh unit score, yolk colour index, yolk ...
