EFFICACY OF FERTILIZATION IN ARTIFICIALLY INSEMINATED TURKEY HENS
POULTRY SCIENCE, 68(5), 724–729.
MeSH headings : Animals; Female; Fertilization; Insemination, Artificial / economics; Insemination, Artificial / methods; Insemination, Artificial / veterinary; Male; Phenotype; Sperm Count / veterinary; Time Factors; Turkeys / physiology
TL;DR:
Gradually increasing weekly inseminated numbers of spermatozoa from 50 to 200 million viable cells/hen as the hens age results in nearly equivalent fertility to that resulting from insemination by 200 million cells each week, which represents a savings of 1.4 billion spermatozosa/hen over a 20-wk laying period.

MAGNESIUM, CALCIUM, AND PHOSPHORUS-CONTENT OF SHELLS FROM HATCHING AND NONHATCHING TURKEY EGGS
POULTRY SCIENCE, 64(5), 1020–1027.
MeSH headings : Animals; Calcium / analysis; Calcium Chloride / pharmacology; Egg Shell / analysis; Embryo, Nonmammalian / drug effects; Embryo, Nonmammalian / physiology; Magnesium / analysis; Magnesium / pharmacology; Magnesium Chloride; Phosphorus / analysis; Turkeys / embryology
TL;DR:
It was concluded that the mineral content of turkey eggshells may influence embryo physiology and hatchability and exogenous calcium at the time of setting significantly depressed hatchability.

VITAL GAS-EXCHANGE AND HATCHABILITY OF TURKEY EGGS AT HIGH-ALTITUDE
POULTRY SCIENCE, 63(7), 1350–1356.
MeSH headings : Altitude; Animals; Diffusion; Egg Shell / ultrastructure; Embryo, Nonmammalian / drug effects; Oxygen / pharmacology; Turkeys / embryology; Turkeys / physiology
TL;DR:
Eggshell cuticle removal from eggshells incubated in oxygen supplemented incubators at high altitudes significantly reduced late embryonic mortality and may be more advantageous to hatchability at high altitude than oxygen supplementation.

CHARACTERIZATION OF INCUBATIONAL EGG WEIGHT LOSSES IN 3 TYPES OF TURKEYS
POULTRY SCIENCE, 61(5), 848–854.
TL;DR:
Increases in preincubation egg weight, egg surface area, and their resulting increased incubational egg weight losses occurred principally during the first 10 weeks of the egg production period in both LW1 and SW1 hens’ eggs.

TURKEY EGG WEIGHT LOSSES AND EMBRYONIC MORTALITY DURING INCUBATION
POULTRY SCIENCE, 61(6), 1209–1213.
TL;DR:
It was concluded that gaseous conductance of some turkey eggshells is insufficient to meet embryonic demands late in incubation.

EFFECT OF INSEMINATION INTERVALS ON OVIDUCAL SPERM STORAGE IN TURKEYS
POULTRY SCIENCE, 60(9), 2150–2156.
MeSH headings : Animals; Breeding; Female; Fertility; Insemination, Artificial / veterinary; Male; Oviducts / physiology; Phenotype; Sperm Capacitation; Turkeys / genetics; Turkeys / physiology
TL;DR:
It is suggested that sperm storage glands fill and empty at the same rates early and late in a breeding cycle, but fewer glands contain spermatozoa in the latter part of the season, resulting in a decreased fertility.
