“…Lower colostrum yield has been reported in sows with two or more obstetrical interventions (Machado, Otto, Bernardi, Wentz, & Bortolozzo, 2016). Longer farrowing length is associated with larger litters and higher number of obstetric interventions at birth (Mellagi, Heim, Bernardi, Bortolozzo, & Wentz, 2009). The fact that the litter size and the percentage of sows with two or more obstetrical interventions did not differ between Control and Induced groups probably also explains why colostrum production was not affected by the farrowing induction.…”

The consumption of colostrum at a low level can compromise the survival and growth of piglets. Therefore, this study aimed to evaluate the effect of farrowing induction on colostrum yield, IgG concentration and the survival and performance of piglets until the weaning. Sows of parity 3 to 7 were assigned into two groups: Control (n = 48), sows with spontaneous farrowing; and induction (n = 48), sows induced to farrow on day 114 of gestation with a PGF analogue. Colostrum and blood samples were collected from the sows, at farrowing and 24 hr later. Blood samples from the piglets were collected at 24 hr after birth. The performance of the piglets was evaluated in a subsample of 28 litters from each group. All piglets were weighed at 7, 14 and 20 days of age. The farrowing length, the number of piglets born alive, stillborn piglets, weight at birth, litter weight at birth and colostrum yield were not significantly affected (p > .05) by farrowing induction. There was no difference between the groups (p > .05) in the percentage of sows with obstetric interventions. Serum IgG concentration, in both sows and piglets, and colostrum IgG concentration were similar between the groups (p > .05). Furthermore, survival rate, piglet weight and litter weight at 7, 14 and 20 days of age were also similar between the groups (p > .05). Therefore, it can be concluded that the farrowing induction performed on day 114 of gestation does not affect the colostrum yield, the IgG concentration in colostrum and serum of piglets, and the litter performance until the weaning.

“…O percentual de primíparas submetidas à intervenção manual no parto foi de 7,6%, próximo dos 10% que SOBESTIANSKY et al, (2001) consideram que a taxa de palpação genital deve ficar, a fim de evitar intervenções desnecessárias, mas diferente dos resultados encontrados por MELLAGI et al, (2009) onde foi encontrado um percentual de 20,6% e de 22,8% observado em estudo realizado por BORGES et al, (2005), ambos efetuados em granjas brasileiras.…”

“…Parity may impact the number of live births, and farrowings of first-parity sows are usually smaller than those of older sows (Bianchi et al 2010). According to Mellagi et al (2009), primiparous sows have longer labor and a higher number of stillbirths during manual obstetric intervention. Since the groups were formed based on sows being diagnosed with UTI and that a higher prevalence of the disease was found in the group whose parity was <6 (50%), it was observed that older breeders are more prone to having UTI, as described by Sobestiansky et al (1999).…”

Correlation between urinary tract infection and reproductive performance of sows

et al. 2018

This study aimed to assess the prevalence and influence of urinary tract infection on the reproductive performance of sows. The animals underwent urine tests using reagent strips and diagnosed as positive or negative. They were then divided into two groups of 30 positive and 30 negative sows for urinary tract infection. Each sow was considered an experimental unit and was followed from labor to weaning. The animals were assessed for their reproductive performance (labor duration, number of live births, mummified piglets, and stillbirths, and postpartum diseases). After weaning, the weaning-estrus interval and rate of return to estrus were assessed. A thermographic camera was used to identify hyperthermia of the mammary system and its relation with the onset of urinary tract infections. The prevalence of urinary tract infection in prepartum sows was 41.1%. Urinary tract infection does not impact labor duration, number of live births, mummified piglets, and stillbirths, number of sows culled, weaning-estrus interval, or return to estrus after insemination. However, it was considered a predisposing factor for the occurrence of postpartum vaginal discharge. There is no correlation between the occurrence of urinary tract infection and mammary system temperature in sows.
