“…A host of factors is thought to contribute to the problem. These include bacterial infection of the udder (e.g., Ross et al, 1981), metabolic disturbances resulting in low blood glucose levels (e.g., Ringarp, 1960), hormonal imbalances (Gooneratne et al, 1982), high ambient temperatures (Fraser, 1970), and various features of management and nutrition (Bäckström et al, 1984, reviewed by Martin andMcDowell, 1975).…”

Daily water intake was monitored for 40 sows during 5 days before and 14 days after farrowing. Intake averaged 9-12 l day-1 before farrowing, dropped to a mean of 6 l on the day of farrowing and increased gradually over 4 days to a plateau of ~14 l day-1. Sows varied greatly in the degree of reduction in intake during the day of farrowing and the first 3 days of lactation, and those sows with low water intake on these days had low average weight gains by the piglets in the same period. Most of the piglet deaths in the study (14 of 19) occurred in the 10 litters whose dam consumed ≤ 6 l day-1 of water from Day 0 to 3 of lactation. Monitoring of 14 sows by time-lapse video recording showed that gross physical activity (percentage of time standing and sitting) varied greatly among sows during the first 3 days after farrowing, with the less active sows having significantly lower water intake. We suggest that some sows are excessively lethargic in the first days after farrowing and fail to consume adequate water, and that this could contribute to low milk production in early lactation.

“…Composition quality of colostrum depends on many different factors relating to the dam, including nutrition (Noblet and Etienne, 1986;Gö ransson, 1990;Migdal, 1991), genetics (Fahmy, 1972;Zou et al, 1992), body condition at parturition (Klaver et al, 1981), health status (Gooneratne et al, 1982) and age. The composition of colostrum has been studied (Darragh and Moughan, 1998) and is known to vary considerably between animals for the reasons stated above.…”

Improving immune status in neonates is crucial to health and production. Gut active carbohydrates (GAC) have been associated with increasing immunoglobin levels and immonucompetence development in mammals. The objective of the following studies was to evaluate whether GAC (mannan-oligosaccharides) applied orally to progeny immediately following parturition, improved blood plasma immunoglobulin (Ig) type G concentrations in piglets and calves. Three trials were conducted comparing control groups with those receiving GAC orally. The first two trials used piglets that were monitored for blood IgG at 2 days of age and for changes in body weight (BW), and the third trial monitored calf IgG from birth to 21 days of age. Piglets in the experimental group received 0.75 g GAC in 10 ml saline at birth and 24 h of age. The calf trial compared the control group against calves that received 22.5 g GAC mixed into 4.5 l of colostrum (to give 5 g/l) in the first 24 h after parturition. Blood serum samples were taken at 2 days post partum in piglets, and at several time points from 6 h to 21 days of age in calves, and were analysed for IgG levels by radial immunodiffusion. In the first piglet trial, significantly higher levels (32%) of IgG were observed for piglets fed GAC ( P , 0.001), and in the second, IgG concentration was elevated by 23% ( P , 0.01) and BW increased by 9% ( P 5 0.023) with GAC supplementation. Significant improvements for calves were recorded at all time points in those fed GAC ( P , 0.05), with an increase in serum IgG observed after the first day, which was maintained throughout the sampling period, resulting in a difference of 39% at the end of the trial (21 d). These findings form a basis for further studies, which are required to investigate possible modes of action involved in enhancing blood immunoglobulin concentrations in young animals, and the longer-term effects this may have on the development of the immune response.

“…Considering that the digestibility obtained in this study was an apparent value, the true digestibility of proteins and DM in porcine colostrum would be essentially 100%. Nutrient composition of sow's colostrum can be influenced by several factors, including variation among sows, varying disease status, genetic difference, dietary regimen, and sow's body fat content (Perrin, 1955;Gooneratne et al, 1982;Zou et al, 1992;King et al, 1993;Jackson et al, 1995;Klaver et al, 1981). In addition, the techniques for collecting the colostrum from the various mammary glands could affect the composition of colostrum or sow milks.…”
