The influence of parity, body condition, litter size and carbetocin administration on colostrum production and immunoglobulin levels in highly productive sows within a tropical environment.

The aim of this study was to explore the factors contributing to colostrum production and the levels of colostrum immunoglobulins (IgG and IgA) in contemporary highly productive sows within a tropical climate. We focused on variables such as parity number, litter size, sow body condition score (BCS), the timing of sample collection following the commencement of farrowing and the use of carbetocin during the birthing process. A total of 100 colostrum samples were collected from a group of 50 Danish Landrace × Yorkshire crossbred sows.

Impact of sow parity on yield and composition of colostrum and milk in Danish Landrace × Yorkshire crossbred sows.

The present study aims to characterize the colostrum, milk yield and composition and to determine whether sow parity would influence yield and composition of colostrum and milk in Danish Landrace × Yorkshire crossbred sows. The data were collected from sow parity numbers 1 (n = 27), 2-4 (n = 48) and 5-6 (n = 30) from Danish Landrace × Yorkshire crossbred sows reared in a commercial swine herd in Thailand. The piglets were weighed on day 0 (<1 h), 1 (24 h), 3, 10 and 17 after birth to determine the colostrum and milk yields of the sows using a prediction equation.
