EFFECT OF FEEDING FAT AND ALTERING WEANING SCHEDULE ON REBREEDING IN PRIMIPAROUS SOWS
JOURNAL OF ANIMAL SCIENCE, 56(1), 21–29.
MeSH headings : Animals; Body Weight; Dietary Fats / administration & dosage; Estrus; Female; Lactation; Pregnancy; Reproduction; Seasons; Swine / physiology; Weaning
TL;DR:
Early weaning of heaviest pigs may improve reproductive performance of primiparous sows in summer and winter, while supplementing lactation diets with fat may improve performance in summer, when weaning-to-estrus interval is longer than in winter.

A COMPARISON OF EXACT AND SEQUENTIAL-METHODS IN MULTISTAGE INDEX SELECTION
THEORETICAL AND APPLIED GENETICS, 66(1), 23–28.
TL;DR:
On a percentage basis, errors in actual percent selected and under-estimation of genetic gain increased with selection intensity while overestimation decreased, and the types of errors which occur and their magnitude depend on the intensity of first stage selection.

Characterization of summer infertility of sows in large confinement units
Theriogenology, 20(1), 133.
TL;DR:
Overall, reproductive performance varied among farm units, was lower in primiparous than in multiparous sows and was reduced during June through October, and the two-way interactions among farm unit, parity and month weaned all affected weaning-to-estrus interval.

JOURNAL OF ANIMAL SCIENCE, 56(4), 820–828.
TL;DR:
Four generations of selection for litter size, 13-wk weight and an index combining litter size and13-wk body weight were conducted in a guinea pig population formed by intercrossing several local lines from different areas of Peru.

SELECTION IN GUINEA-PIGS .1. ESTIMATION OF PHENOTYPIC AND GENETIC-PARAMETERS FOR LITTER SIZE AND BODY-WEIGHT
JOURNAL OF ANIMAL SCIENCE, 56(4), 814–819.
MeSH headings : Analysis of Variance; Animals; Body Weight; Female; Guinea Pigs / genetics; Guinea Pigs / physiology; Litter Size; Male; Phenotype; Pregnancy; Selection, Genetic
TL;DR:
Data on 202 sires, 718 dams and 3,192 progeny from a selection experiment were used to estimate phenotypic and genetic parameters for litter size and body weight in guinea pigs and results agreed very well with realized heritabilities and genetic correlations obtained from selection.

It is suggested that crossbreeding boars were more sexually active than purebred boars, perhaps due to an advanced physiological or behavioral stage.
