Identifying early indicator traits for sow longevity using a linear-threshold model in Thai Large White and Landrace females [PDF]
Animal Bioscience, 2021 Objective The objective of the study was to investigate the possibility of utilizing an early litter size trait as an indirect selection trait for longevity and to estimate genetic parameters between sow stayability and litter size at different parities ...

Genetic Parameters of Bovine Serum Immunoglobulins
Journal of Dairy Science, 1985 Radial immunodiffusion techniques were used to determine serum concentrations of immunoglobulins G1, G2, M, and A in 1,293 daughters of 282 Holstein-Friesian sires from 31 herds in southwestern Ontario, Canada. Mean serum immunoglobulin concentrations (mg/100 ml) were 2,163, 2,409, 531, and 107 for immunoglobulins G1, G2, M, and A, respectively.
