Pumpkin and garden cress seed oils as feed additives to improve the physiological and productive traits of laying hens

This study aimed to investigate the effects of adding pumpkin (PK) and garden cress (GC) seed oils laying diets, as nutraceuticals, on physiological productive performance layers. A total 360 hens, at 24 weeks age, were randomly equally assigned into four groups nine replicates each (10 birds/replicate). The 1st group was fed basal diet served a control. 2nd, 3rd, 4th diets supplemented with 0.5% PK oil, GC 0.25% oil + respectively. experiment lasted eight weeks. According results, (0.5%) oils, well their combination (PK CG 0.25%), had significant positive (p ≤ 0.05) several biochemical parameters, such cholesterol triglycerides, some traits, egg production mass hens. They also positively affected birds’ blood antioxidant superoxide dismutase (SOD) Malondialdehyde (MDA), improved immunological response globulin, lymphocytes, heterophils. Additionally, they enhanced yolk fatty acids, oleic linoleic. Therefore, we recommend natural feed additives, either separately or in (0.25%+0.25%), improve functions traits birds.
