infectious agents cause disease in virtually any susceptible hosts. in the poultry production and medicine, pathogens were eliminated from a line of a breeder by injection of antibiotics into hatching eggs. there is little information available describing the safety of the folate antimetabolite/sulfonamide class of antibiotics on the game birds embryonated eggs. the objective of this study was ...

The present trial was conducted to investigate the effect of using bay leaf powder and its oil on male semen characteristics, female reproductive traits, plasma hormonal alteration hatchability local quails. results were summarized uses different levels (Laurel nobilis L.) as feed additives in quail diets significantly (P≤0.05) higher body weight, testis relative gonadosomatic index, size area ...

A study was carried out to examine the hatchability of guinea fowls eggs and performance of keets under the traditional extensive system. A short questionnaire to ascertain production scope and management practices were administered to a total of ten farmers; five farmers from each of two communities, using purposive sampling. In order to establish some actual production indices, data was colle...

Two peaks of embryo mortality have been identified during incubation of chicken eggs (the first and the final phases of incubation), and both are linked to egg turning. Turning in the first week enables proper formation of extra-embryonic membrane and in the final week avoids embryo malpositioning. The hatchability of the eggs, however, may depend on physiological parameters (e.g., hormone leve...

The present acute shortage of eggs for donation cannot be overcome unless adequate guidelines are set to alleviate the anxieties regarding payments, in cash or kind, to donors. The current Human Fertilisation and Embryology Authority (HFEA) guidelines do not allow direct payment to donors but accept the provision of lower cost or free in vitro fertilization (IVF) treatment to women in recogniti...

Biological control is considered one of the most used alternative measures to combat helminths relevance in veterinary medicine and public health. Among these parasites, Toxocara canis stands out for its high prevalence worldwide distribution, addition being main cause visceral larva migrans man. The present work aimed fungus Pochonia chlamydosporia (isolate Pc-10) on eggs T. canis. In order do...

objective: fungal agents cause disease in virtually any susceptible hosts. in the poultry production and medicine, pathogens were eliminated from a line of a breeder by injection of antifungals into hatching eggs. there is little information available describing the safety of the antifungal drugs on the birds embryonated eggs. the objective of this study was to investigate the efficiency of the...

objective: in recent years, antiviral drugs have been used widely in the glob to prevent and treat viral diseases. they injected into eggs to eliminate pathogens and prevent of egg transmission of disease, but the adverse effects of drugs have always been a major concern. there is little information available about the safety of antiviral drugs in the embryonated eggs of birds. the objective of...

EFFECT OF EGG STORAGE CONDITIONS ON THE HATCHABILITY AND CHICK QUALITY DUCKS This study was conducted at the French Group Company Al-Sadat City in Menoufia Governorate to investigate effect of different pre-incubation egg storage period on weight loss, hatchability, hatch window, duckling quality, immunity, and its body weight.  384 fertile eggs were collected from 200 females Pekin ducks (Ana...
