Abstract

To explore the effect of fixed-time artificial insemination (FTAI) on earlier embryonic development and fertility of gilts, in experiment 1, totally 43 gilts (Jinwu pig) were randomly divided into control (n=24) and FTAI groups (n=19). The control group were natural estrus, and performed artificial ...

Abstract

A synthetic progestin altrenogest (ALT) is used to synchronize the estrus cycle of swine for fixed-time artificial insemination (AI) and has been shown to improve follicular development and reproductive performances in post-weaning sows. However, the effects of ALT treatment on reproductive tracts, ...

Abstract

Context: Smallholder pig production systems in the north-eastern region of India are characterised by inefficiency due to use of unselected local pigs, and multiple breeding constraints such as paucity of superior germplasm, high mating costs, and poor access to artificial insemination (AI)....

Abstract

Objective: Insemination with spermatozoa, seminal plasma and extender, cause a rapid inflammatory response in pig endometrium, characterized by an influx of neutrophils into the uterus. The transient inflammatory response to semen involves cytokine induction. Potential functions for Interleukin-23...

Abstract

To determine effects of timed artificial insemination (TAI) hormonal treatments on reproductive performance of gilts/sows and explore molecular mechanisms, gilts (TAI: 90; Control:149; Total: 239) and sows (TAI: 370; Control: 492) were utilized. Results indicated the estrus/farrowing rate and...

Abstract

Background: Identification of relevant in vivo biomarkers for fertility remains a challenge for the livestock industry. Concentrations of the small peptide hormone oxytocin (OXT), involved in male reproductive function and present in the seminal plasma (SP) of several species could be a robust one. ...

Abstract

Retained cytoplasmic droplets (CD) are the most frequent sperm abnormality in boar semen. A high incidence of CD is associated with subfertility, but the underlaying reasons are not well understood. The storage of extended semen might augment the adverse effects of CD on essential steps towards...

Abstract

This study aimed to identify risk factors affecting PBW, high CVPBW and the occurrence of IUGR piglets in 12 commercial Danish herds with hyperprolific sows using free-access stalls, floor or electronic sow feeding systems in the gestation unit. The following factors were investigated: the duration ...

Abstract

Changes in sperm morphology have an impact on the fertility of swine reproducers, with losses in the productive indexes, constituting one of the causes of discarding males. In this context, the objective was to identify more frequent abnormalities in semen samples from boars that failed, at an...

Abstract

This study aimed to evaluate boar sperm characteristics and proteins, in relation to their importance regarding in vivo fertility. Sixty-five ejaculates were used and 468 sows (parity ≥ 2) were inseminated. Sperm CASA kinetics, morphology, viability, DNA fragmentation, mitochondrial membrane...
