Abstract

Goat milk coagulation properties (gMCP) are important trait for the cheesemaking industry but are rarely included in national breeding programs. In the present study, we monitored goat milk quality traits and gMCP of Slovenian Alpine goats within a single flock (N = 77), reared in the same common environment over three-year period. In addition, using pedigree data, we looked for correlations among dams, daughters (N = 32 pairs) and gMCP. Traditional gMCP measurements were introduced into a 4-parameter curd firmness over time (CF$_t$) model. Several gMCP parameters were associated with parity and stage of lactation. Most notably, estimated rennet coagulation time (RCT$_{eq}$), curd firmness at 15 (a$_{15eq}$) and 20 min (a$_{20eq}$) after rennet addition were strongly correlated between dams and their daughters. These results support further research of genetic parameters for gMCP and the inclusion of breeding value predictions for gMCP in national breeding programs.
