The research investigates the effects of prolonged storage of hatching eggs on eggshell conductance (G) and embryonic metabolism of Ross 308 broiler breeder eggs. Hatching eggs were collected, weighed and stored for 10 days. After 10 days, a second group of eggs was collected as in the first, weighed and stored for additional 4 days to set up two pre-incubation storage treatments (4 days and 14...

The objective of this study was to compare the effects of feed supplementation of laying hens with manganese from its inorganic and organic sources on performance and some parameters of egg quality. Ninety-six hens at 20 weeks of age were randomly allocated to 4 dietary treatments, each consisting of 6 replicates (4 birds per replicate). The control group was fed unsupplemented basal diet (BD) ...

objective: both the length of extra-alveolar time and type of storage media are significant factors that can affect the long-term prognosis of replanted teeth. this study aims to compare propolis 50%, propolis 10%, hank’s balanced salt solution (hbss), milk and egg white on periodontal ligament (pdl) cell survival for different time points. materials and methods: in this in vitro experimental s...

In animal tissues the virus of herpes simplex is very stable and can be preserved at refrigerator temperature or in the frozen state for many months. Egg-adapted herpes virus, on the other hand, is said to be relatively unstable so that it cannot be satisfactorily preserved and stored (Scott, 1948a,b). Two recent standard texts on viruses state that "egg virus appears harder to keep, very littl...

A novel approach was used to evaluate the distribution of sperm in the oviduct of turkey hens inseminated before or after the onset of egg production. Prior to insemination, sperm were stained with the nuclear fluorescent stain bisbenzimide. Sperm distribution in the sperm storage tubules (SST) of the uterovaginal junction and the infundibular tubular glands was determined by use of simultaneou...

Poultry production at all scales of operation is wholly dependent on the supply of day-old chicks. Fertility and hatchability are two major parameters that highly influence the supply of day-old chicks. Fertility refers to the percentage of incubated eggs that are fertile while hatchability is the percentage of fertile eggs that hatch. It is therefore important to understand the factors that in...

background: tooth avulsion is one of the most severe dental traumas which most often occur in children. when immediate replantation is not possible, storage in a proper media may lead to a prolonged survival rate. aloe vera is a cactus like plant with green, tapered leaves that are filled with a transparent viscous gel. this medicinal plant has significant anti-inflammatory, antioxidant, antiba...
