MeSH headings : Animals; Caseins / analysis; Cattle; Chymosin; Dairying; Genetic Variation; Italy; Milk / chemistry; Milk / standards
TL;DR: This study suggests that selection for RCT and a30 should not be performed on correlated traits such as SCS or CAS but on direct measures because the ability of milk to coagulate is improved through the causal effect that the former play on the latter, rather than from a common source of genetic variation.

Genetic parameters for fertility of dairy heifers and cows at different parities and relationships with production traits in first lactation

MeSH headings : Animals; Cattle / genetics; Cattle / physiology; Female; Fertility / genetics; Fertility / physiology; Lactation / genetics; Lactation / physiology; Models, Genetic; Parity; Pregnancy; Quantitative Trait, Heritable
TL;DR: The result indicates that fertility in heifers is a different trait than fertility in lactating cows, and hence it cannot be used as robust indicator of cow fertility, and milk yield depends on both pMY and LL, and, as such, is a cause and consequence of (in)fertility. (via Semantic Scholar)
