Malnutrition remains a leading contributor to the morbidity and mortality of children under the age of five worldwide. However, the underlying mechanisms are not well understood necessitating an appropriate animal model to answer fundamental questions and conduct translational research into optimal interventions. One potential intervention is milk from(More)
Colostral administration practices on dairy farms have significantly improved over the last 15-20 years resulting in prevalence of calves ingesting insufficient colostrum decreasing from 35-40% to 19%. Despite these improvements, the serum immunoglobulin G (IgG) concentration of ≥ 1000 g/dl and serum total protein (TP) concentrations of ≥ 5. 2 g/dl are(More)
In calves, passive immunity of immunoglobulins can be acquired through ingestion of colostrum or colostrum replacers. Plasma can been used to supplement immunoglobulins in healthy or sick calves. Serum half-life of colostral derived immuglobulin G (IgG) is estimated to be 20 days. Half-life of IgG is important in determining response to antigens and timing(More)
OBJECTIVE timely initiation of antenatal care (i.e. within the first trimester) is associated with attendance of the full recommended regimen of antenatal visits. This study assessed social and behavioural factors that affect timely initiation of antenatal care in Kigali, Rwanda from the perspective of health facility professionals. DESIGN health facility(More)
OBJECTIVE To compare the apparent efficiency of absorption of IgG and failure of passive transfer of immunity rates between calves fed colostrum by nipple bottle (NB) and oroesophageal tubing (OET). DESIGN Randomized controlled study. ANIMALS 26 Holstein bull calves (age, 4 to 8 hours). PROCEDURES Calves were randomly assigned to receive colostrum by(More)
BACKGROUND Estimation of the quantity of colostral IgG or serum IgG absorbed following ingestion of colostrum by calves is essential for monitoring the effectiveness of colostrum feeding practices on dairy farms. Milk total solids concentrations determination is a critical part of quality assessment of nonsaleable whole milk prior to feeding to calves. To(More)
