Management and Production Factors Influencing Immunoglobulin G1 Concentration in Colostrum from Holstein Cows
Open accessAbstract
Immunoglobulin G1 concentration was measured in 919 first milking colostrums from Holstein cows during a 4-yr period on a commercial dairy farm. Sources of variation analyzed for effect on colostral IgG1 concentration were season of calving, lactation number, dry period length, intercalving interval, complete lactation milk and fat production, weight of first milking colostrum, and time from calving to first milking. Weight of first milking colostrum was the variable most highly correlated (negatively) with colostral IgG1 concentration (r = -.29). Weight of first milking colostrum and lactation number of the cow were the most significant discriminators between colostrum of low and high IgG1 concentration. The implications of these results for colostrum feeding management are discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
