Abstract
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. These samples were taken at two distinct time intervals: right after farrowing (0 h) and 6 h later. The colostrum samples were classified according to the sows' parity numbers, with 33 samples originating from primiparous sows and 67 from multiparous ones. Additionally, the number of live-born piglets were categorized into three groups: 7-13, 14-17 and ≥ 18 piglets per litter. Moreover, the samples were categorized based on the use of carbetocin during the birthing process, with 34 sows experiencing natural farrowing and 66 sows receiving carbetocin. The sow's BCS was assessed through visual evaluation and palpation. The piglet colostrum consumption and the amount of colostrum produced by the sows were determined. The concentrations of IgG and IgA were determined by using the enzyme-linked immunosorbent assay (ELISA) technique. On average, the colostrum production averaged 5.5 ± 1.7 kg, with IgG and IgA concentrations averaging 54.9 ± 24.6 mg/ml and 7.6 ± 3.5 mg/ml, respectively. Primiparous sows exhibited a significant 25.2% decrease in IgG concentration within 6 h of parturition (P < 0.05), whereas no such decline was observed in multiparous sows. Furthermore, multiparous sows displayed higher colostrum yields (6.2 ± 1.5 kg and 4.3 ± 1.5 kg, respectively, P < 0.001) and IgA concentrations compared to primiparous sows (8.3 ± 3.8 mg/ml and 6.3 ± 2.6 mg/ml, respectively, P = 0.002). Furthermore, a positive correlation was observed between IgA concentrations in colostrum and the sow's BCS at both the 0-h and 6-h post-farrowing time points (r = 0.425, P = 0.002 and r = 0.315, P = 0.031, respectively). The administration of carbetocin did not yield a significant impact on the concentrations of IgG and IgA in the sows' colostrum (P > 0.05). In conclusion, during the initial 6 h after birth, colostrum IgA levels remained stable, whereas there was a noticeable decline in IgG levels, particularly among primiparous sows. The production volume of colostrum and the concentration of IgA in sows within tropical conditions were influenced by both parity number and body condition score.
