Passive transfer of colostral immunoglobulins has long been accepted as imperative to
optimal calf health. Many factors, including timing of colostrum ingestion, the method and …

The newborn calf is dependent upon colostrum for disease resistance because the
separation of maternal and fetal blood supplies prevents the in utero transfer of immune …

Refractometry using a Brix refractometer has been proposed as a means to estimate IgG
concentration in bovine maternal colostrum (MC). The refractometer has advantages over …

Acquisition of high quality colostrum is an important factor influencing neonatal calf health.
Many methods have been used to assess the Ig concentration of colostrum; however …

The objectives of this study were to determine the immunoglobulin G (IgG) content of
colostrum on Alberta dairy farms and to determine which on-farm tool, the colostrometer or …

In colostrum collected 0–80h postpartum the contents of immunoglobulins (Igs), transforming
growth factor beta-2 (TGF-β2), insulin-like growth factor-1 (IGF-1) and growth hormone (GH) …

Background Changes in colostrum composition of Egyptian buffaloes and Holstein cows
collected at calving, 6, 12, 24, 48, 72, 96, 120 h and after 14 days of parturition were studied …

The immunoprotective properties of bovine milk immunoglobulin G (IgG) have led to a recent
proliferation of nutritional products incorporating this protein. It has therefore become critical …

The objectives of this study were to identify factors associated with colostral specific gravity
in dairy cows, as measured by a commercially available hydrometer (Colostrometer) …

Forty-five Holstein calves were fed milk replacers containing either antibiotics [MRA
(oxytetracycline at 138 mg/kg and neomycin at 276mg/kg), n= 22)] or Enteroguard [MRE, a …
