EVALUATION OF MATING SYSTEMS INVOLVING 5 BREEDS FOR INTEGRATED BEEF-PRODUCTION SYSTEMS .4. ACCOUNTING FOR VARIABILITY AND GENETIC TRENDS
JOURNAL OF ANIMAL SCIENCE, 71(3), 587–594.
author keywords: BEEF CATTLE; CROSSBREEDING; SIMULATION; EFFICIENCY
MeSH headings : Animals; Body Weight / genetics; Breeding / economics; Cattle / genetics; Cattle / growth & development; Computer Simulation; Efficiency; Female; Genetic Variation; Male; Meat / standards; Models, Biological; Sex Characteristics
TL;DR:
Computer models were used to simulate integrated cow-calf-feedlot production systems and accounting for genetic trends and variation for weights caused breeds to be ranked differently when evaluated at low Choice.

EVALUATION OF MATING SYSTEMS INVOLVING 5 BREEDS FOR INTEGRATED BEEF-PRODUCTION SYSTEMS .2. FEEDLOT SEGMENT
JOURNAL OF ANIMAL SCIENCE, 70(3), 700–713.
author keywords: BEEF CATTLE; CROSSBREEDING; FEEDLOTS; SIMULATION; EFFICIENCY
MeSH headings : Adipose Tissue / growth & development; Animal Feed; Animal Husbandry / economics; Animals; Breeding; Cattle / genetics; Cattle / growth & development; Computer Simulation; Costs and Cost Analysis; Crosses, Genetic; Energy Intake; Energy Metabolism; Female; Hybrid Vigor; Male; Meat / standards; Models, Biological; Weight Gain
TL;DR:
Computer models were used to simulate the feedlot segment of an integrated beef production system and found that British breed combinations were most efficient at a fat-constant end point for megacalories of ME per kilogram of gain and input costs per carcass value.

1992 journal article
EVALUATION OF MATING SYSTEMS INVOLVING 5 BREEDS FOR INTEGRATED BEEF-PRODUCTION SYSTEMS .3. INTEGRATED SYSTEM
JOURNAL OF ANIMAL SCIENCE, 70(3), 714–722.
author keywords: BEEF CATTLE; CROSSBREEDING; SIMULATION; EFFICIENCY
MeSH headings : Animal Husbandry / economics; Animals; Body Weight; Breeding; Cattle / genetics; Cattle / growth & development; Computer Simulation; Crosses, Genetic; Female; Male; Models, Biological
TL;DR:
Crossbred combinations involving British (A or H) and Continental (C or S) breeds were more efficient than other crossbred combinations at all end points; however, choosing specific breed combinations for integrated systems depends on slaughter end points, market end points (weight vs lean), and measures of efficiency (weight, lean, or value basis).

1992 journal article
Evaluation of mating systems involving five breeds for integrated beef production systems: I. Cow-calf segment
Journal of Animal Science, 70(3), 689.
MeSH headings : Animal Husbandry / economics; Animals; Birth Weight / genetics; Body Weight / genetics; Breeding; Cattle / genetics; Cattle / growth & development; Cattle / physiology; Cattle Diseases / genetics; Computer Simulation; Costs and Cost Analysis; Crosses, Genetic; Dystocia / genetics; Dystocia / veterinary; Energy Intake; Energy Metabolism; Female; Fertility / genetics; Hybrid Vigor; Lactation / genetics; Male; Models, Biological; Pregnancy; Reproduction / genetics
TL;DR:
Deterministic computer models were used to simulate the cow-calf segment of an integrated production system andCrossbred combinations containing Angus and Hereford ranked more biologically and economically efficient than other breed combinations, whereas Continental purebreds ranked more economically efficient.

Evaluation of crossbreeding systems for small beef herds: II. Two-sire systems
Journal of Animal Science, 67(1), 40.
MeSH headings : Animal Husbandry / methods; Animals; Breeding; Cattle / genetics; Crosses, Genetic; Evaluation Studies as Topic; Female; Hybrid Vigor; Insemination, Artificial / veterinary; Male; Models, Biological
TL;DR:
Increasing the complexity of the system did not provide important improvements in traits measured and no differences were found between corresponding natural-service and AI systems for weights sold and incomes.
