CORRELATED RESPONSES IN GROWTH AND BODY-COMPOSITION OF REPLICATED SINGLE-TRAIT AND INDEX SELECTED LINES OF MICE

THEORETICAL AND APPLIED GENETICS, 49(3), 133–144.

By: E. Eisen n & T. Bandy n

TL;DR: In agreement with theory, antagonistic index selection generally yielded smaller genetic responses than single trait selection in lines of mice selected in the following ways: W+Tio, increased six-week body weight (WT6); W ° Ti+, increasedSix-week tail length (TL6); W+Ti−, increased WT6 and decreased TL6; W−Ti+, decreased WT7; M16, increased three-to six- weeks postweaning gain (PWG); and (via Semantic Scholar)

BODY-COMPOSITION AND ENERGETIC EFFICIENCY IN 2 LINES OF MICE SELECTED FOR RAPID GROWTH-RATE AND THEIR F1 CROSSES

THEORETICAL AND APPLIED GENETICS, 49(1), 21–34.

By: E. Eisen n, H. Bakker n & J. Nagai n

TL;DR: Partitioning of correlated response differences between M16 and H6 into average direct and average maternal genetic effects indicated that average direct genetic effects, favoring M16, were responsible for the major difference between the selected populations. (via Semantic Scholar)

REPRODUCTIVE-PERFORMANCE OF BRACON-HEBETOR (HYMENOPTERA-BRACONIDAE) FEMALES WITH MORE OR FEWER THAN NORMAL NUMBER OF OVARIOLES

ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA, 70(4), 577–582.

By: R. Petters n & D. Grosch n

TL;DR: Wasps with fewer than 4 ovarioles produced proportionately fewer eggs than their “normal” 4-ovariole sisters, and in females with 5–9 ovariolaes, egg production did not increase significantly, suggesting the supply of vitellogenic materials is a limiting factor. (via Semantic Scholar)

MANAGING REPRODUCTION IN DAIRY-CATTLE .3. CHANGES IN CULLING PATTERNS WITH INCREASED REPRODUCTION

JOURNAL OF DAIRY SCIENCE, 60(7), 1125–1132.

By: L. Brannen n, L. Ulberg n & R. Zimbelman*

TL;DR: Overall the progestogen system for managing reproduction shifted cause of culling from reproduction to milk production and culling for mastitis or poor udder increased slightly. (via Semantic Scholar)
