Campylobacter coli is an important species involved in human cases of enteritis, and chickens are carriers of the pathogen mainly in developing country. The current study aimed to evaluate the transmission of C. coli and its pathogenic effects in chicken embryos. Breeder hens were inoculated intra-esophageally with C. coli isolated from chickens, and their eggs and embryos were analyzed for the...

Embryo and hatchling survival diminish as turkey breeder hens age. Recent data indicated that a chelated calcium proteinate (CCP) additive given to turkey breeder hens improved embryo survival as hens aged but did not affect shell thickness. We hypothesized that the mechanism by which this occurred may be by improved functional shell quality and its consequent effect on cardiac physiology. To t...

Avian mycoplasmosis is an important disease of poultry of great economic importance. It is caused by four (4) pathogenic mycoplasma species namely Mycoplasma gallisepticum, Mycoplasma synoviae, Mycoplasma meleagridis and Mycoplasma iowae; although other Mycoplasma species have also been incriminated in the disease. The disease causes cough, rales, ocular and nasal discharges, decreased feed int...

Genetic selection in primary broiler breeders may modify skeletal structure, possibly impeding semen transfer, and could alter the size and degree of fluctuating asymmetry (FA) of bilateral traits associated with fertility. Hence, we hypothesized specific morphometric traits could predict differential fertility. Sixty primary broiler breeder males from Strains A and B (n = 30/strain) were indiv...

Analysis of field data collected over several years in three poultry housing systems (narrow caged-layer houses, high-rise caged-layer houses, and broiler-breeder layer houses) indicated that the baited jug-trap was a reliable method of sampling house flies, Musca domestica L.; sticky ribbons provided additional information on two other fly species. Relative frequency of house fly capture indic...

An assessment of the thermal control mechanisms applicable to solid breeder blanket designs under ITER-like operating conditions is presented in this paper. Four cases are considered: a helium gap; a sintered block Be region; a sintered block Be region with a metallic felt at the Be-clad interface; and a Be packed bed region. For these cases, typical operating conditions are explored to determi...

increase in feed intake of broiler breeder hens, results to incidence of metabolic and hormonal changes and finally leads to poor reproductive performance. an experiment was conducted to evaluate responses of feed-satiated and feed-restricted laying breeder hens to daily injection of an acute dose of progesterone (p4). a total of 64 cobb 500 hens were fed either restricted or ad libitum from 27...

This study aimed to prove that giving hCG injection at the time of artificial insemination and five days afterartificial in dairy cows with repeat breeder can cause pregnancy. employed 30 dairycows breeder. All samples were divided into two treatments, P1 using adose 100 IU given intramuscularly P2 a dose of100 after insemination. The results analyzed Chi-Square test. Analysis showed all treatm...

Ideally, the ITER base blanket would provide the necessary tritium for the reactor to be self-sufficient during operation, while having minimal impact on the overall reactor cost, reliability and safety. A solid breeder blanket has been developed in the CDA phase in an attempt to achieve such objectives. The reference solid breeder base blanket configurations at the end of the CDA phase has man...
