EFFECTS OF PREGNANT MARE SERUM GONADOTROPIN ON REPRODUCTION IN 4 GENOTYPES OF GILTS

JOURNAL OF ANIMAL BREEDING AND GENETICS, 110(5), 363–373.

By: D. Lubritz n, E. Eisen n & O. Robison n

TL;DR: The increase in ovulation rate and number of embryos generated by PMSG seems to be negated by fetal losses occurring both before and after 40 d of gestation. (via Semantic Scholar)

1991 journal article

EFFECT OF SELECTION FOR LITTER SIZE AND BODY-WEIGHT ON HORMONE-INDUCED OVULATION RATE IN MICE

JOURNAL OF ANIMAL SCIENCE, 69(11), 4299–4305.

By: D. Lubritz n, E. Eisen n & O. Robison n

author keywords: SELECTION; OVULATION RATE; SUPEROVULATION; MICE
MeSH headings : Analysis of Variance; Animals; Body Weight / genetics; Breeding; Female; Least-Squares Analysis; Litter Size / genetics; Mice / genetics; Mice / growth & development; Mice / physiology; Ovulation / genetics
TL;DR: Genetic differences in natural vs hormone-induced ovulation rates were compared in immature female mice from five lines that had undergone long-term single-trait and antagonistic index selection for litter size and 6-wk BW to indicate significant differences among lines in ovarian response to exogenous hormones.

1991 journal article

Genetic parameters for testosterone production in boars

Journal of Animal Science, 69(8), 3220.

By: D. Lubritz n, B. Johnson  n & O. Robison n

MeSH headings : Adipose Tissue / anatomy & histology; Animals; Birth Weight / genetics; Breeding; Gonadotropin-Releasing Hormone / pharmacology; Male; Regression Analysis; Swine / genetics; Swine / physiology; Testis / anatomy & histology; Testis / metabolism; Testosterone / blood; Testosterone / metabolism; Weight Gain / genetics
TL;DR: This study suggests that testes measurements are good predictors of both basal and challenge testosterone levels, and selection for increased testis size or increased testosterone levels would be expected to enhance growth. (via Semantic Scholar)

1989 journal article

Age of cow and age of dam effects on milk production of Hereford cows

Journal of Animal Science, 67(10), 2544.

By: D. Lubritz n, K. Forrest n & O. Robison n

MeSH headings : Age Factors; Animals; Birth Weight; Cattle / physiology; Female; Lactation; Pregnancy; Regression Analysis; Weaning
TL;DR: It appears that age of dam should be considered in evaluation of cow performance, as a lasting detrimental effect of older cows on lactation yield of daughters is suggested. (via Semantic Scholar)
