Use of lactation curves for analysis of milk production data.
Nonlinear equations were compared with categorical analysis to account for DIM effects on milk production. Five different models for lactation curves were evaluated. Derived from a multiphasic lactation curve, the selected lactation curve appeared to result in random residuals and performed more consistently than the multiphasic curve. Residuals from the fitting of lactation curves were then us...
متن کاملHeritability Estimates for First Lactation Milk Yield of Registered and Nonregistered Holstein Cows
Heritabilities of milk yield and fat test were estimated from first lactation records of 196,672 Holstein daughterdam pairs separately for registered and nonregistered cows for four milk yield groups and by years of freshening of the daughter. The model included herdseason and sire of the daughter. Heritability estimates were similar for registered and nonregistered cows averaging about .33 for...
متن کاملShort communication: Projecting milk yield using best prediction and the MilkBot lactation model.
The accuracy and precision of 3 lactation models was estimated by summarizing means and variability in projection error for next-test milk and actual 305-d milk yield (M305) for 50-d intervals in a large Dairy Herd Improvement Association data set. Lactations were grouped by breed (Holstein, Jersey, and crossbred) and parity (first vs. later). A smaller, single-herd data set with both Dairy Her...
متن کاملCubic-spline interpolation to estimate effects of inbreeding on milk yield in first lactation Holstein cows
Milk yield records (305d, 2X, actual milk yield) of 123,639 registered first lactation Holstein cows were used to compare linear regression (y = β(0) + β(1)X + e), quadratic regression, (y = β(0) + β(1)X + β(2)X(2) + e) cubic regression (y = β(0) + β(1)X + β(2)X(2) + β(3)X(3) +e) and fixed factor models, with cubic-spline interpolation models, for estimating the effects of inbreeding on milk yi...
متن کاملFine Mapping of Milk Yield Qtl on Chromosomes 6 and 20 in German Holstein Population Using Microsatellite Markers
In German Holstein population a very signifi cant QTL with effects on milk yield trait (MY) was mapped on chromosome 6 and 20 to the interval BM143–ILSTS97 and AGLA29–ILSTS72, respectively. Where, three markers BM143, FBN13 and ILSTS97 on chromosome 6 and two markers AGLA29 and ILSTS72 on chromosome 20 were associated with highly signifi cant effects (P<0.01) for milk yield. Findings from this ...
