background: asthma is a chronic inflammatory disorder of the airways. the available treatment options have major limitations owing to low efficacy, associated adverse events and compliance issues. therefore, the health burden of bronchial asthma is increasing globally at an alarming rate, providing a strong impetus for the development of new therapeutics. myrica sapida is known traditionally in...

An experiment was conducted to determine whether egg quality during the late stage of egg production can be improved by using diets that are effective in reducing egg size. The experiment was conducted in completely randomized design with six treatment groups and four replicates each with ten hens from 94 to 106 wk of age. Three 28-d periods used for different dietary factors including: 1) Cont...

Researchers are trying to boost the immune system of poultry birds through use natural immune-stimulants including bee venom. There is a scarcity in literature about venom for ovo injection studies. The aim this study investigate effect two levels freeze-dried (BV) (10 and 20 µg/egg) into eggs Alexandria breeder hens at 18-day incubation on hatchability percentage, hatching weight per egg weigh...

this experiment was conducted to evaluate the effects of different levels of biohebal® feed supplement on performance, egg traits, blood biochemical and immunity parameters of laying hens. experiment was conducted in a completely randomized design with 144 of hy- line (w36) laying hens from 23 to 34 weeks of age in 4 treatment and 3 replicate (with 12 bird in each replicate) and included: contr...

this trial was conducted to evaluate the effects of different dietary factors that affect egg cholesterol concentration in laying hens of 56 to 70 weeks of age. three hundred and ninety six hy-line w36 laying hens were subjected to 11 experimental treatments, each treatment consisting of 4 replicates, each replicate of 9 hens. dietary treatments included the control, made up of corn plus soy me...

The extent of urea denaturation depends on the concentration of protein and urea and also on the temperature of the solution. Egg albumin solutions (0.9 per cent) are not denatured by 20 per cent urea, denature slowly with 25 per cent urea, and denature rapidly with 35 per cent urea at room temperature. At a higher temperature 30 per cent urea is rapidly effective. Denaturation of the egg album...

METAPHOSPHORIC acid is considered to be a protein-precipitating reagent. Pohl [1889], Lorenz [1890], and Fuld [1902] analysed precipitates obtained from proteins with metaphosphoric acid. Their results did not lead to any important interpretation because at that time the knowledge of protein chemistry was not yet sufficiently developed. In 1935 Schofield gave theoretical reasons for assuming a ...
