1. A strain of meningococci obtained directly from the spinal fluid of a patient has been propagated in serial passage in 10 to 12 day old chick embryos without change in its essential characteristics. 2. The chick embryo is susceptible to infection with the meningococcus, and, depending on its stage of development, reacts to the infection with more or less specific lesions. 3. In chick embryos...

Stocks of three Indian Chandipura virus (CHPV) isolates; one isolate from an adult febrile case in 1965 from Chandipura town, Maharashtra, and two isolates from two pediatric encephalitis cases from Andhra Pradesh, 2003 were inoculated in 10-day-old chick embryos by allantoic route. All three virus isolates replicated in chick embryos showing titre of log 10(12) to log 10(13) EID50. The results...

Aqueous extracts of 11-day-old chick embryos enhance the growth of tubercle bacilli in oleic acid-albumin media. These extracts also increase the tendency of virulent strains to exhibit the serpentine pattern of growth and confer this property on avirulent variants which normally grow unoriented in clumps. Growth in the presence of chick embryo extract slightly increases the virulence of the vi...

the purpose of this study was to investigate the relationship of maternal breeding values of the weight of day-old chick chicks in a commercial broiler line with egg traits including yolk fatty acids. maternal breeding values of 63 hens of known pedigree were estimated through an animal model, containing direct additive genetic effect, maternal additive genetic effect, maternal common environme...

Quality meat-type chickens refer to color-feathered and slow-growing chickens, are developed from local breeds and taste better than fast-growing broilers. Due to the lovely appearance and wonderful taste, quality chickens are considered as alternatives to fast-growing broilers in some regions of the world, such as in Europe and East Asia, and the output of quality chicken meat is rising each y...

objective(s): this study aimed to find out whether the chick cardiomyocyte micromass (mm) system could be employed to predict the teratogenecity of common environmental factors. different multivitamins and over the counter drugs were used in this study.   materials and methods: white leghorn 5-day-old embryo hearts were dissected and trypsinized to produce a cardiomyocyte cell suspension in dul...

Abstract The purpose of this research was to examine the impact varying doses ginger powder on broiler productivity. There were 180 commercial strain Ross 308 day old chicks utilized in experiment, and each chick weighed allocated randomly among four treatments. Three different treatments tested, with a replication 15 chicks. diet supplemented 0.5, 1.0 2.0g/kg powder, respectively, as control. ...

The study was carried out to determine the effects of the parental age and egg weight of Japanese quail on the weight of one day old chick, fertility and hatchability of incubated eggs. Three hundred and sixty Japanese quail eggs were obtained from 22 and 36 weeks old quails. The eggs were weighed and grouped into 2 categories: Light (7.5-9.5g) and Heavy (9.6 – 12g). The weight of the chicks we...

The total iron content of an egg of average size is about 0.8 to 1.0 mg. of Fe. Both the poultryman and the consumer are interested in the possibility of increasing the amount of iron above this figure. The poultryman is devoting his efforts to the production of eggs which contain the maximum amounts of the essential elements and compounds needed for the development of strong and sturdy chicks....

A study of the activity and distribution of glutamic dehydrogenase in various tissues of the developing chick embryo has recently been made (Solomon, 1957). It was found that glutamic dehydrogenase showed marked fluctuations of activity in certain tissues at various stages of development. However, as only relatively low amounts of the enzyme were found in all tissues of the chick embryo and fow...
