The quality of the day-old broiler chick is foremost in the minds of many poultry managers. From fertilised ovum to the placement at the broiler farm, some factors such as the characteristics of the incubating eggs, the egg holding conditions, the incubation conditions and the conditions that exist between hatching and placement at the farm and their interactions may affect chick quality. It ma...

Hind guts of 9i-day mouse embryos were transplanted into the posterior part of the coelomic cavity of 2|-day chick embryos. The hosts were sacrificed after 1-7 days and the mouse primordial germ cells (PGCs) in the graft and in the surrounding host tissues were searched for by means of the histochemical technique for alkaline phosphatase. Altogether 94 grafts were examined. During the first 3 d...

a 3 × 3 factorial experiment with three levels of fennel extract (fe) (0, 50, and 100 mg/kg of diet) and three levels of added vitamin d3 (vit d3) (0, 3500 and 4200 iu/kg of diet), was carried out to evaluate reproductive performanceand immune response of post molted broiler breeders(76-84 weeks).broiler breeders were weighed at 10 week after molting (74 weeks) then randomly distributed into 36...

The modern broiler and breeder are performing at levels never seen before. In order to multiply by 15x (or more) their bodyweight in just four weeks, they do not have the time to correct the effects of nutritional deficiencies. In a recently published paper coming from the University of Alberta, the effect of genetic selection was studied using unselected strains from 1957, 1978 and a 2005 comm...

Myopia is characterized by an increase in axial length of the eye, but the reasons for the axial elongation are still unknown. Higher intraocular pressure (IOP) has been associated with myopia and could be involved in eye enlargement. The purpose of this study was to investigate the effect of intraocular pressure on the geometry of the chick eye and to investigate whether an increase in IOP cou...

The study aimed to investigate the effect of in ovo (IO) leptin injection on yolk sac concentration, embryo development, blood lipid metabolism, and biochemical parameters broiler chicks during early post-hatching period. Hatching eggs were weighed placed an incubator with 100 eggs/4 replications/group. groups were: non-injected group (C); 3 injected μl phosphate buffer solution (PBS); 0.5 (L0....

The Livestock Product Processing Technology Laboratory is one of the centers practicum, research or community service activities at Banyuwangi State Polytechnic where it has a hatchery machine with capacity 500 grains, been modified so that temperature and humidity can be controlled properly, but still some disadvantages. In addition to frequent errors in heater, system used uses an on/off cont...

three hundred and sixty male day- old ross 308 broiler chicks were randomly assigned to four dietary treatments in order to evaluate the effect of propolis as growth promoter on the performance and the immune response of the broiler chicks to the nd vaccine. each treatment contained three replicates of 30 chicks. dietary treatments were as follow: a corn - soy meal diet (control diet).control d...

A study was conducted to evaluate the production and hatching performances of hilly chickens naked neck (NN) at areas Naikhongchari regional station research farm Bangladesh Livestock Research Institute (BLRI). The experimental were reared in an open-sided poultry house under intensive management system for a period 18 month. birds allowed take feed clean drinking water ad libitum. Data on prod...
