Informal care is a vital pillar of the British welfare state. A well-known fact in the small economic literature on informal care is the apparent negative relation between care responsibilities and labour market participation. Yet, caring and labour market participation may be endogenous. Using an instrumental variable approach and panel data techniques and employing data from the British House...
Life history traits such as fecundity are important to evolution because they make up components of lifetime fitness. Due to their polygenic architectures, such traits are difficult to investigate with genetic mapping. Therefore, little is known about their molecular basis. One possible way toward finding the underlying genes is to map intermediary molecular phenotypes, such as gene expression ...
The aim of this study was to evaluate the effects of dietary vitamin E on reproductive and productive parameters in Japanese quails. A total number of 240 female and 80 male Japanese quail were divided into five treatments with four replications in a completely randomized design. Experimental diets were zero control, 30, 60, 120 and 240 mg kg-1 of vitamin E. Fertility and total hatch...
This experiment was performed to evaluate the effect of in ovo injection carbohydrates, antioxidants, and their combination into stored incubating eggs. To conduct this research, 600 hatching eggs were selected for amniotic (on 17.5th embryonic day) from laying hens Cobb 500 strain after 14 days storage, hatching, they distributed a rearing period 5 treatments replicates completely randomised d...
Poultry is one of the most important subsectors livestock, supplying a cheap source good quality animal protein in form meat and eggs. This study was conducted to assess egg fertility, hatchability parameters indigenous chickens Hulla, Aleta Wondo Dale districts, representing highland, midland lowland agroecologies, respectively. Six kebeles (two from each district) were purposively selected ba...
egg drop syndrome (eds) is caused by a hemagglutinating adenovirus which has become a major cause of lost egg production and sever economic losses in breeder and layer chicken flocks throughout the world. a pcr assay was optimized for detection of eds virus in inoculated allantoic fluids (afs) of duck and chicken emberyonated eggs. two strains of eds viruses were propagated in allantoic cavity ...
ABSTRACT Background and Objectives: Cryptosporidium parvum is a coccidian protozoan that causes diarrhea in immunocompromised humans and newborn animals. The severity of the disease depends on the immunological status of the affected. Cryptosporiosis can have lethal effects on immunocompromised individuals such as AIDS patients. About 10% of...
This research is about manufacture nanopowder Bioceramics from local materials used Ball Milling for biomedical applications. Source materials for the manufacture of medicines are plants, animal tissues, microbial structures and engineering biomaterial. The form of raw material medicines is a powder before mixed. In the case of medicines, research is to find sources of biomedical materials that...
The present study was conducted to determine the external and internal egg quality of Isa Brown (Gallus gallus domesticus) chicken and Japanese quails (Coturnix coturnix japonica) as affected by storage time under room temperature in the hot weather conditions of Nigeria. Parameters evaluated included egg weight, albumen and yolk indices. For each species, a total number of twenty freshly laid ...
