1980 journal article
Ovulation rate, embryo survival and ovarian sensitivity to gonadotrophins in mice selected for litter size and body weight
Journal of Reproduction & Fertility, 59(2), 329.
MeSH headings : Animals; Body Weight; Chorionic Gonadotropin / pharmacology; Female; Fetal Death; Follicle Stimulating Hormone / pharmacology; Gonadotropins / pharmacology; Litter Size; Male; Mice; Mice, Inbred ICR; Ovary / drug effects; Ovulation; Pregnancy; Selection, Genetic
TL;DR:
Single trait selection of mice for either large body size or large litter size resulted in an increased ovulation rate because of possible enhanced ovarian sensitivity to gonadotrophins and there was no difference in pre-implantation embryonic survival in either of the selected lines.

GENETIC-RESISTANCE OF CHICKENS TO AFLATOXIN ASSESSED WITH ORGAN-CULTURE TECHNIQUES
AVIAN DISEASES, 24(2), 415–422.
TL;DR:
A chick tracheal-organ-culture model system was used to evaluate the sensitivity of various strains of chickens to aflatoxin B1, with male chicks more resistant than female chicks and within-category strains and sex differed significantly in sensitivity to damage by a flatoxin.

INFLUENCE OF EARLY-PREGNANCY ON REPRODUCTIVE RATE IN LINES OF MICE SELECTED FOR LITTER SIZE
THEORETICAL AND APPLIED GENETICS, 57(5), 209–220.
TL;DR:
The influence of male-induced early puberty on female reproductive rate was determined in three lines of mice differing in litter size and body weight, suggesting that the physiological state of the very young female was not optimum for normal pregnancy.

MeSH headings : Animal Nutritional Physiological Phenomena; Animals; Body Weight; Female; Litter Size; Male; Mice / genetics; Mice / growth & development; Mice / physiology; Postnatal Care / veterinary; Pregnancy; Reproduction
TL;DR:
The established genetic differences in litter size among lines due to selection were considerably larger than the maternal environmental effect due to postnatal litter size.

EPISODIC FLUCTUATION OF TOTAL ESTROGENS IN PERIPHERAL-BLOOD OF BULLS - EFFECTS OF ESTRADIOL-17-BETA ON LH AND TESTOSTERONE SECRETION
BIOLOGY OF REPRODUCTION, 23(5), 1029–1037.
MeSH headings : Animals; Cattle; Estradiol / pharmacology; Estrogens / blood; Glucocorticoids / blood; Kinetics; Luteinizing Hormone / blood; Male; Testosterone / blood
TL;DR:
E can be included with LH, T, and CC as hormones whose peripheral concentrations fluctuate in an episodic manner and administration of pharmacological levels of E2 can result in an acute increase in levels of circulating LH and T.

MeSH headings : Animals; Breeding; Cattle / genetics; Cattle / growth & development; Female; Hybrid Vigor; Male
TL;DR:
Means of crossbreds generally exceeded means of parental breeds, especially body weight, and heterosis for weight increased with age through 18 mo and declined by 30 mo of age.

OVULATION, OVARIAN-FUNCTION, AND REPRODUCTIVE-PERFORMANCE AFTER TREATMENTS WITH GNRH IN POSTPARTUM SUCKLED COWS
THERIOGENOLOGY, 13(2), 171–181.
TL;DR:
Two experiments were conducted to determine whether treatments with gonadotropin releasing hormone (GnRH) during the early postpartum period in suckled cows would induce ovulation and initiate regular estrous cycles.

EFFECT OF LITTER SIZE AT BIRTH ON LACTATION IN MICE
JOURNAL OF ANIMAL SCIENCE, 50(4), 680–688.
MeSH headings : Animals; Animals, Newborn / growth & development; Body Weight; Female; Lactation; Litter Size; Mice / growth & development; Pregnancy
TL;DR:
The data provide no evidence to support the hypothesis that increased fetal number or mass results in a greater lactational output by the dam, and multiple regression analyses indicated that dam body weight at parturition consistently accounted for more of the variation in 12-day litter weight than litter size.
