this study was conducted to compare the effect of various commercial in-feed disinfectants on layer performance, intestinal microflora, and egg cholesterol. one hundred and eight layer hens (lsl, 24 wks of age) were divided into six groups consisting: control, formaycin-200 ppm, formalin-200 ppm, and nanosilver in feed-15 ppm or drinking water-7.5 ppm. there were no differences between experime...

This experiment was conducted, during a seven-week period to investigate, the effects of using various levels of garlic cloves and turmeric rhizome powders, on laying hens’ performance, egg quality characteristics and cholesterol content in yolk. Two hundred and sixteen, 27-weeks old Novogen white laying hens were assigned randomly into nine treatments with eight replicates of three birds each....

Objective: The experiment was conducted to evaluate the effect of different levels of germinated barley on performance and egg quality in laying hen. Methods: One hundred and twenty laying hens, 44-weeks old, Lohmann LSL hens were used in this experiment. Birds were assigned randomly to the groups, each of which consisted of 20 birds (4 replicate cages each containing 5 birds). The experiment w...

This study was conducted to evaluate the effects of dietary supplement-ation of rosemary essential oils (REO) and zinc (as zinc sulfate) on performance, egg quality traits, and some serum biochemical metabolites of laying hens. A total of 144 44-weeks-old Lohmann LSL-Lite laying hens were randomly allocated into four treatments, each comprising six replicates of six birds. The first group was s...

The substitution effect of noug (Guzoitia abyssinica) seed cake with samma (Urtica simensis) leaf meal (SLM) was investigated on egg production and egg quality parameters in commercial layer hens. Five treatment (T) diets were formulated to contain SLM at 0% (T1), 3% (T2), 6% (T3), 9% (T4) and 12% (T5) by substituting noug seed cake. One-hundred fifty Isa Brown layer pullets w...

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 ...

this study was conducted to investigate the effects of using gracilariopsis persica in layer diet on performance, egg quality and lipids of blood serum of layer hens. one-hundred hy-line w-36 hens were allocated to five dietary treatments (experimental diets containing 0, 5, 10, 15 and 20 percent seaweed) and five replicates and four birds in each for 12 week period (23-34 week of age). the res...
