Popis:The effect of yeast culture and cell wall supplementation during the prepartum period in mares on colostrum quality, passive immunity transfer, and foal growth was evaluated. The experiment was conducted in an equine production system in western Costa Rica. Twenty Purebred Spanish mares were assigned to one of two treatments, with a total of 10 replicates each: an unsupplemented control and supplementation with 30 g of a commercial product during the 30 days prior to the estimated foaling date. After foaling, colostrum samples were collected using modified syringes, and the total immunoglobulin concentration in the colostrum was evaluated using an equine colostrometer. Blood samples were taken from foals 24 hours after birth to determine immunoglobulin G (IgG) concentration, and foal growth was assessed until day 45. No significant differences (p > 0.05) were found in colostrum immunoglobulin concentrations between treatments (equine colostrometer: 1.07 ± 0.006 and 1.08 ± 0.006; handheld refractometer: 25.20 ± 1.63 degrees Brix and 25.30 ± 1.62 degrees Brix,  for the control and supplemented groups, respectively). Significant differences (p < 0.05) were found for immunoglobulin G concentration in foal blood serum (2548.95 ± 234.39 mg/dl and 1403.43 ± 234.39 mg/dl, for the control and supplemented groups, respectively). No significant differences (p > 0.05) were found in body weight at the different evaluation time points or in average daily gain of the foals between treatments. It is concluded that, under the conditions of this study, supplementation with cell walls and yeast cultures in prepartum mares had no effect on colostrum quality or on foal growth but did affect the concentration of immunoglobulin G in foal serum.
