Extract

An adequate intake of colostrum by the newborn piglet allows the piglet to acquire passive immunity and develop active immunity. However there is relatively little information on the composition of colostrum from sows of modern genotypes. The purpose of the study was therefore to investigate the changes in IgG concentration of colostrum and the uptake of colostrum by piglets.

A total of 9 muciparous sows (Newsham - Large White x Landrace) were observed whilst farrowing naturally. Colostrum was sampled, without using oxytocin, at 0, 3, 6, 9, 12, 15, 18, 21 and 24 h post partum from the anterior, middle and rear thirds of the udder and frozen at -20 °C. Colostrum intake was measured as soon as piglets began to suckle after being born, by removing three piglets/sow from the sow and weighing the piglets before and after a period of suckling, the mean weight change over eight consecutive weighings (corrected for urinary losses) being taken as colostrum intake. Piglets were observed to determine on which udder section the piglet was suckling. IgG concentration was measured using an ELISA technique (Varley et al, 1985). Statistical analysis was carried out using analysis of variance.
