The present study aimed to investigate the effects of different risk factors on stillbirth piglets born from oxytocin-assisted parturitions.Data were collected a total 1121 74 Landrace x Yorkshire crossbred sows herd. Logistic regression models used determine associations between and including parity (1, 2, 3-5, 6-10), gestation length (GL) (112-113, 114-116, 117-119 days), litter size, birth order (BO), sex, interval (BI), cumulative farrowing duration, weight (BW), crown rump length, BW...
The effects of second litter syndrome (SLS) on subsequent reproductive performance remain poorly understood. This study examined the impact SLS parameters such as piglets born alive (PBA), accumulative number PBA (APBA), farrowing interval (FI), and risk decreased (DPBA) up to parity 5.
In recent decades, pig production has focused on increasing birth litter size (Koketsu et al., 2017).However, large positively correlates with long farrowing duration and increases stillbirth rate (Fahmy Friend, 1981;Borges
Background and Aim: Dystocia in swine can increase the stillbirth rate; however, its importance pig-breeding systems has been underestimated. Until now, few studies have investigated dystocia associated risk factors. Therefore, this study, we aimed to evaluate effects of various factors on swine. Materials Methods: Out 5,557 piglets, included 4,997 piglets analysis study. The dependent variable was dystocia, which recorded when a birth interval exceeded 45 min or obstetric assistance...
Stillbirth causes considerable loss to the pig farming industry. Methods aimed at reducing stillbirth should base on understanding of risk factors for intrapartum because it accounts 75% all stillbirths. Unfortunately, few studies have differentiated between and prepartum stillbirths leading inadequate information about sole stillbirth. This study investigated piglet's stillbirth.Data 1527 piglets born from 103 sows in one herd were recorded. Generalized linear mixed models used determine...
The information about risk factors for a high stillbirth rate in piglets is inadequate. Therefore, this study was conducted to determine important an extremely commercial pig farm Vietnam.This included 628 and 45 Landrace × Yorkshire sows. Data including parity number, gestation length (GL), litter size (LS), piglet's gender, stillbirth, birth order, interval (BI), cumulative farrowing duration (CFD), weight (BW), crown-rump (CRL), body mass index, ponderal index (PI) were collected. To deal...
Recent studies have shown that probiotic supplementation during late gestation exerts some beneficial effects on reproductive performance of the sows. This study aimed to investigate Bacillus subtilis QST 713 in gilts different criteria. A total 94 Camborough-48 at day 85 were randomly allocated into 2 groups: (1) control diet; (2) diet + 4 × 108 CFU per day. Gilts supplemented until farrowing. At farrowing, litter size, number piglets born alive, stillbirths, mummies, birth weight,...
Modern pig farming worldwide has been facing substantial economic loss due to perinatal mortality which is mainly associated with the farrowing process.Therefore, present study aimed identify factors affecting duration in natural sows intensive indoor conditions.In total, 210 4 commercial farms were included study.The association between potential risk and was analyzed by using general linear models.Two final models demonstrated that number of total born piglets, stillborn mummified litter...
Few studies have investigated risk factors for dystocia in swine, although this birthing abnormality can compromise welfare of both sows and piglets by increasing stillbirth rate decreasing sow productivity. This study aimed to determine associated with at piglet level cloprostenol-induced farrowings. A event was recorded when a birth interval exceeded 45 min or manual extraction applied. Data were collected from 898 born 77 Landrace × Yorkshire crossbred sows, which induced farrowing on day...
Previous findings regarding the effects of farrowing induction on characteristics sows are controversial. This study aimed to investigate following characteristics: (1) Proportion that farrowed during working hours, (2) stillbirth rate, (3) number stillbirths per farrow, (4) dystocia rate (5) (the proportion farrowings had at least one event), (6) events duration, (7) birth interval, and (8) weight.Thirty-eight Landrace x Yorkshire were randomly allocated into two groups; control group...
Probiotics are used at different stages of gestation to promote reproductive performance in sows. This study investigated the effect
The present study aimed at examining the association between different risk factors and intrapartum stillbirth in piglets born from cloprostenol-induced farrowing sows. This enrolled 898 within 77 Landrace x Yorkshire sows subjected to induction using cloprostenol day 114 of gestation. Generalized Linear Mixed Models were used determine important indicators for piglet level. Investigated included parity, gestation length, litter size, birth order, piglets' gender, interval, cumulative...
Oxytocin is commonly used to shorten farrowing duration in sows. Therefore, determining the optimal time for this application necessary. This study investigated effects of oxytocin administration at different points during parturition on stillbirth rate, birth interval and determine moment crated The information 1914 piglets born after was collected. three studied parameters groups were compared. results showed that rate minimized when 5th before 8th piglets. shortest piglet 9th piglet. 6th...
Prolonged farrowing duration increases stillbirth in piglets and affects maternal health leading to a decrease the reproductive performance of sow. The present study aimed predict postpartum vaginal discharge (PVD, day) sows. Data were collected from 204 mixed parity Landrace X Yorkshire sows swine farm Bacninh province, Vietnam. Parity, gestation length, litter size, number dead-born (NDB), (FD, h), manual extraction (ME) recorded. Postpartum was monitored twice day until no detected two...
The present study aimed to investigate factors influencing the prolonged birth interval in swine, defined as a longer than 30 minutes. In total, 3380 piglets born from 239 Landrace x Yorkshire sows 5 farms North of Vietnam were included this study. dependent variable was interval, and independent variables parity, gestation length, litter size, relative order, crown-rump weight, body-mass index, ponderal piglet’s gender, dead-born piglet, oxytocin use. Important for determined by using...
