Multi-omics analysis reveals Parabacteroides distasonis and Kineothrix alysoides as potential key bacterial species associated with anemia in sows [PDF]
Background Sow anemia has been reported to be associated with reduced reproductive performance. Additionally, anemia may alter gut microbiota composition.

Reducing dietary crude protein for gestating and lactating sows reduces daily nitrogen retention, but reproductive performance is not impacted by diet protein concentration [PDF]
Background Soybean meal (SBM) is a primary protein source in swine diets, but partial replacement with crystalline amino acids (AA) is commonly used to reduce dietary protein. Adequate dietary protein and energy are essential to support fetal development,

Unraveling the relationship between the vaginal microbiome and return to estrus in post-weaning sows [PDF]
Background Return to estrus in post-weaning sows has a significant impact on reproduction performance. Changes in sex hormone levels influence the composition of the vaginal microbiota in sows.

A pilot study on differential expression of microRNAs in the ventromedial prefrontal cortex and serum of sows in activity restricted crates or activity free pens [PDF]
Objective Physical activity restriction in sows may lead to behavioral abnormalities and affective disorders. However, the psychophysiological state of these sows is still unclear.

Activated crystalline silicon dioxide mitigates weight loss in lactating sows
This study investigated activated crystalline silicon dioxide (SIL) supplementation in late pregnancy and lactating sows on reproductive parameters as well as the performance of suckling piglets. Eighty sows were assigned to two groups: control (CON, n =

Of a total of 31,766 pregnancies 465 abortions were reported, in average 1.46 %. By comparison of the frequency of abortion at different times of the year a significantly higher percentage of abortion was found in sows inseminated during the summer months. No significant difference was found between 68 boars as to the frequency of abortion.

Nurse sow strategies in the domestic pig: I. Consequences for selected measures of sow welfare
Management strategies are needed to optimise the number of piglets weaned from hyper-prolific sows. Nurse sow strategies involve transferring supernumerary new-born piglets onto a sow whose own piglets are either weaned or fostered onto another sow. Such

Effect of feeding on reproductive performance of Cajamarca creole sows over two first reproductive cycles [PDF]
An experiment was conducted to evaluate the effects feeding in Cajamarca Black Creole sows on reproductive performance. Sows (24 nulliparous) were assigned randomly within to 2 treatments and maintained on these treatments for up to 2 reproductive cycles.
