Serum progesterone, enzymes, and electrolytes of hens laying a low or high incidence of shell-less eggs. 1983

D A Roland, and D N Marple, and R N Brewer, and P A Teer, and F J Hoerr

Three experiments were conducted to determine possible differences in serum progesterone, enzymes, and electrolytes between hens laying a high or low incidence of shell-less (SL) eggs. Blood was taken at time of oviposition and at 6, 12, 18, and 25 hr later, irrespective of the stage of the sequence. The results indicated no significant differences in average serum progesterone between hens laying a high or low incidence of SL eggs. In general, the patterns of serum progesterone in relation to time of oviposition was similar for each type. No significant differences were observed in serum phosphorus, magnesium, glutamate pyruvate transaminase, or alkaline phosphatase between hens laying a high or low incidence of SL eggs. It was concluded that the production of SL eggs is not related to abnormal serum progesterone, alkaline phosphatase, glutamate pyruvate transaminase, magnesium, or phosphorus levels.

UI	MeSH Term	Description	Entries
D008274	Magnesium	A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
D010058	Oviposition	The process of laying or shedding fully developed eggs (OVA) from the female body. The term is usually used for certain INSECTS or FISHES with an organ called ovipositor where eggs are stored or deposited before expulsion from the body.	Larviposition,Larvipositions,Ovipositions
D010063	Ovum	A mature haploid female germ cell extruded from the OVARY at OVULATION.	Egg,Egg, Unfertilized,Ova,Eggs, Unfertilized,Unfertilized Egg,Unfertilized Eggs
D010758	Phosphorus	A non-metal element that has the atomic symbol P, atomic number 15, and atomic weight 31. It is an essential element that takes part in a broad variety of biochemical reactions.

D011201	Poultry Diseases	Diseases of birds which are raised as a source of meat or eggs for human consumption and are usually found in barnyards, hatcheries, etc. The concept is differentiated from BIRD DISEASES which is for diseases of birds not considered poultry and usually found in zoos, parks, and the wild.

D011374	Progesterone	The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.

D002645	Chickens	Common name for the species Gallus gallus, the domestic fowl, in the family Phasianidae, order GALLIFORMES. It is descended from the red jungle fowl of SOUTHEAST ASIA.	Gallus gallus,Gallus domesticus,Gallus gallus domesticus,Chicken

D004573	Electrolytes	Substances that dissociate into two or more ions, to some extent, in water. Solutions of electrolytes thus conduct an electric current and can be decomposed by it (ELECTROLYSIS). (Grant & Hackh's Chemical Dictionary, 5th ed)	Electrolyte
